Analysis: granite on how to clean paint or paint

Paint or paint dripping on the granite, in addition to adhering to its surface, there are still some shallow penetration into the stone surface. Cleaning before the first blade with a thin strip of pollution on the surface layer of stone, and then use the selected cleaning agent started cleaning. The choice of cleaning agent, if you have previous experience of cleaning the same or similar, then you can go directly to select your experience and use the appropriate cleaning agent. Otherwise, you have to try to make the appropriate selection and trial, but avoid the abuse and the use of chaos.

Sandstone general, the majority of organic pigments for paints and cleaning solvents are more sensitive to agents, but try to choose some volatility for a long time to dissolve in water or solvent cleaning agents. When used under the circumstances, or wipe or immersion. For the removal of paint or paint on the wall, due to liquid cleaning agent flows easily in the facade, will have to clear the way through the applicator, or use some cream and cleaning agents. But no matter the kind of cleaning agents or methods used, the best in small areas prior trial, in determining the amount of after effects and widespread use.

Need to pay attention to what the use of natural stone

Natural stone, with its solemn, natural charm, has always been one of the designers like to use the materials. However, the trend of promoting environmental protection in recent years, it seems that allowing consumers prohibitive. In fact, as long as the scientific use of stone is not so terrible.

Natural stone has a certain degree of radioactivity, therefore, consumer choice, do be careful, when used to science. Below, a brief selection and use of natural stone three issues need attention.

First, the pre-selection methods and criteria to master. Stone at the level of radiation is divided into A, B, C categories, according to regulations, only the A class can be used for home decoration. Marble and granite stone are mainly two types of radiation are generally lower than marble granite, most can be used for interior decoration, and extensive use of granite should not be in the room, especially not in the bedroom, the elderly, children, the use of countertop . According to the test, put different colors of the stone of its choice of red, green or red blotches with granite varieties.

Second, the purchase invoice to sign a contract. Contracts and invoices is an important guarantee of rights, consumers should ask the seller expressly in the contract, the product name, size, grade, quantity and price, and require a clear by what standards for testing. Can ask the seller to provide the best products, proof of compliance by the legal department as the inspection reports or products of radioactive certificate. Conditions permit, it is best to test the samples for testing departments. Now, appearing on the market the so-called "international A-class", "super" in stone, some manufacturers are misleading consumers, a practice that consumers should pay attention to prevention.

Third, to be taken after the laying of diluted pollution. Harmful only 3.2 days half-life of radon, indoor radon concentration 20 minutes after the open doors and windows can be reduced to -30 minutes after the outdoor levels. Therefore, the simplest way is to enhance ventilation. Best to just renovate the room to detect substandard if the test can be used to reduce radiation lead-free paint or install shield to prevent the release of radon from building materials. If the radioactive targets too high, the stone must be replaced immediately.

Analysis: Conservation of artificial stone countertops to be "carrot and stick"

Currently the mainstream in the market is divided into three man-made stone countertops: artificial quartz stone countertop, pure and composite acrylic table acrylic table. According to press the investigation, the three tops, the former sales staff is often referred to as quartz stone countertops, the latter two are often called artificial stone countertops. In the above table, the product performance are quite different.

Many consumers in the choice of the cabinet table, the more like the use of artificial stone, because the ability of its shape, the overall cost cheaper than natural stone. However, artificial stone products on the market the quality of good and bad, consumers are often puzzled. In addition, some consumers ignore the latter part of the artificial stone care and maintenance, not knowing that the life extension of artificial stone countertops are also essential.

Artificial stone countertops, "bully"

Artificial stone countertops crack is found difficult to remedy, the most important is to understand the characteristics of artificial stone, artificial stone countertops to extend the service life, maintenance is the key.

According to report, is currently the mainstream in the market is divided into three man-made stone countertops: artificial quartz stone countertops, pure and composite acrylic table acrylic table. According to press the investigation, the three tops, the former sales staff is often referred to as quartz Slate countertops, the latter two are often called artificial stone countertops. In the above table, the product performance are quite different.

Sales in the cabinet table for many years, said Zhang Zhiyuan, quartz stone countertops main component is silicon dioxide, the highest hardness of this type of table, so the possibility of a fracture is very small, but also more wear-resistant.

Zhang Zhiyuan acrylic knife in the composite sample scratched several times, the sample had a white scratch. Compared with quartz stone countertops, less wear resistance of acrylic products, acrylic products, especially the compound, "compound from the resin + acrylic + acrylic masterbatch composition, it is far from pure resistant acrylic products mill, "said Zhang Zhiyuan this outspoken.

Decision quality acrylic content

"Artificial stone countertops abrasion, strong factor is that the content of acrylic." EU to send cabinet shop salesman Shilihe Ma indicated that the general content of artificial stone acrylic 40% to 45 % between the most stable, which is the industry known as pure acrylic, it's the most superior overall performance.

Pure acrylic products currently on the market to import brands. Mr Ma also said that "as long as aluminum hydroxide, to ensure the materials used, not mixed with calcium carbonate, we can guarantee the hardness between the pure acrylic products of natural stone and hard wood between the crack is not easy."

Zhang Zhiyuan reminded, in the purchase of artificial composite acrylic stone, you need to carefully consult the vendors for the data, with particular attention to resin content, table manufacturers to reduce production costs, often by increasing the acrylic resin content and lower levels, in which case, the table is not wearable, more importantly, this approach likely to cause aging and yellowing of the table.

■ Diagnosis

Chopping vegetables at the table cracks

Problem Diagnosis: 1, probably because the cabinet table are caused Shouli Bu. When the installation is usually not reinforced table pad section, and vegetable pad location article is not just in part. Therefore, this is more like a vegetable in the air, if the hardness of artificial stone countertops is not high enough, long time it will simply force in the formation of cracks in parts. Many cabinet plant protection measures for the central table is not enough to become a crack spread of the central table of the "disastrous." 2, man-made causes of the possibility of cracks in the smallest cabinet, unless the course was particularly hard on the table chop chop things.

Article pad cracks at the table

Problem Diagnosis: 1, plate material or the pad itself, a problem section, if the relatively poor use of timber, tank seepage or leakage, such cases will certainly pad expansion, this expansion led to the table cracking. 2, the expansion joints in the table is not enough to stay the case, thermal expansion and contraction occurs due to climate reasons, but also easily lead to cracking of the table. 3, the cabinet table below does not pad the entire board, or a cushion pad may be a result of uneven cracking.

Crack between the sink and stove tops

Problem Diagnosis: 1, the opening may cause improper cracking, either sink or stove hole, should be curved around it, after opening, should also be installed around the floor plate in the hole to increase the loading capacity; 2 , in the "L" shaped and "U"-shaped table, if the cabinet installation is not flat, sinking deformation of the late cabinet, easily lead to cracks in the corner of the table.

Cone Crusher card machine how to do?

Cone crusher in the foreign body can not break through the crushing chamber overload the machine or for some reason, the cone crusher spring safety system to achieve insurance, cone crusher port of Sandstone increases. Foreign matter from the exhaust cone crusher chamber, such as foreign body stuck in the row of clean ore chamber system can be used to make row of ore continues to increase, the foreign body discharge cone crusher chamber.

Cone crusher in the spring under the effect of discharge port automatically reset, cone crusher machine to resume normal work. Crushing cavity surface covered with wear-resistant high manganese steel liner. Population size of discharge using hydraulic or manual adjustment.

Cone crusher work, the rotation of the motor through the pulley or coupling, cone crusher, cone crusher cone shaft and the Department of dynamic force in the eccentric sleeve around a fixed point for the rotation a week pendulum movement. So that the crushing cone near the broken wall sometimes and sometimes put to leave the solid-mounted in the adjustment of the rolling acetabular wall surface, so that ore constantly under attack in the crushing cavity, squeezing and bending role in crushing ore achieved. Bevel gear drive motor through the eccentric rotation, the broken cone pendulum movement for the spin. Cone sometimes broken and sometimes left near the fixed cone, complete crushing and nesting.

Support the connection sleeve and the frame body pressed by spring, when the broken piece of metal into the Slate and other objects can not be broken, the spring deformation is generated, discharged foreign body, to achieve the insurance, to prevent damage to the machine.

Crusher Precautions during use

Jaw crusher in the installation process, often fail due to operator error or debugging of the production process Slate planted hidden dangers.

How jaw crusher installation is correct?

First, cracker no-load test

1; Jaw Crusher 2 hours continuous operation, the bearing temperature must not exceed 30 ℃.

2; Jaw Crusher all fasteners should be firm, not loosening.

3; flywheel, tank rounds and smooth running.

4; jaw broken machine parts without all the friction and abrasion, debris and grinding out the phenomenon, no unusual sound.

5; Jaw Crusher discharge opening of the adjusting device should be able to ensure that the adjustment range of discharge opening.

Second, cracker-load test

1; crushing machine cycle or may not have a significant impact, crash.

2; Max feed size should meet the design requirements.

3; continuous operation 8h, bearing temperature must not exceed 30 ℃.

4; crusher capacity and product size should meet the design requirements.

5; adjust the seat and seat rack ear was not significantly rocky ledge.

Third, cracker preparation before use

1; double-check is good, the thrust plate connections have enough grease.

2; carefully check all fasteners are tightened.

3; double-check the drive belt is good. If there is insecurity, should be replaced, when the drive belt or pulley when there is oil, oil rag and wipe applications.

4; check the protective device is good. Found that insecurity, should be immediately removed.

5; check whether the ore crushing cavity or debris. If ore or debris, you must clean up to ensure that the crusher cavity start.

6; check whether the bolts from the top to return, whether the compression gasket set, T-shaped bolts are tightened.

Fourth, jaw crusher items checked before starting

1; upon inspection, proved that conditions are normal parts of the machine, before starting.

2; jaw broken machine to allow only the case in the no-load starting.

3; start, you must use the tone or signal prior warning.

4; starts, if there is not normal, they should stop immediately. Not to be identified and excluded from normal circumstances, be re-starting the crusher.

V. cracker production use

1; jaw crusher normal operation only after the feed production.

2; to be broken by adding the material should be evenly crusher cavity, lateral feeding should be avoided or filled with feeding, so as not to overload or under unilateral overload.

3; normal working hours, bearing in temperature should not exceed 30 ℃, the maximum temperature not exceeding 70 ℃. Over the temperature should immediately stop and identify the cause and to be eliminated.

4; parking, you should first stop feeding until the crushing cavity material is fully discharged only after the power off.

5; broken when the material as a result of crushing cavity caused by parking congestion, immediately turn off the power to stop running, clean up the broken cavity material, before re-starting.

6; jaw plate one end of the wear and tear, you can turn around to use.

7; jaw broken machine to use for some time, should re-tighten the adapter sleeve, adapter sleeve to prevent loosening of the damage to the machine.

No matter how much any machine is not the workload, with emphasis on maintenance. Properly maintained equipment will play his greatest efficiency. Jaw crusher relatively small parts are easily marble, pay attention to the matters to eradicate broken material produced during the operation of machinery in the major incident.

How to stone waxing is better?

With the stone in the extensive use of people's lives, people living in the stone has become a beautiful landscape. Stone as a relatively high-end building materials, daily maintenance is extremely important. The right stone conservation in order to better show the stone's quality and beauty. Conservation of stone, stone waxing also major problem. This article introduces you to the specific stone waxing program.

(A), stone floor cleaning Sandstone

Stone ground clean and bright, cloth wax evenly, no stains.

(B), stone floor cleaning, waxing, polishing and maintenance procedures

1, from the wax:

Tools and materials: brush machine with water tanks, washing scouring needle seat with a black brush (brown, red, scouring brush), suction machine, suction skin scraping wax from the water.

(1) to open the machine to the work site, set a good washing needle seat, and even scouring brush;

(2) Install a water tank with good water from the wax;

(3) pressing the power switch on the fuselage, so the chassis driven scouring brush needle seat rotation.

Note: When the handle up, the body moves to the right; the handle down, body to the left;

(4) pressing the lever will play a tank of water evenly rub the wax on the ground;

(5) control of the machine direction, from left to right, back and forth 2 or 3 times;

(6) of the alternating up and down about 10 cm;

(7) has been completed, with a suction machine to suck water from the wax;

(8) corner position with long-handled brush drag wiping hands twice;

(9) twice with water;

(10) to be carried out after the ground dried wax.

2, waxing:

Tools and materials: wax off the tractor, mop bucket, squeeze water heater, the end of wax, face wax.

(1) to drag down the wax off the wax caps in the rack;

(2) the saturated wax tractors;

(3) pressing the water heater on the tractor to the trailer on the folder until the wax does not drip;

(2) the body flat, pull the handle to control the dial up, so dial with scouring brush close to the ground;

(3) When power switch, the dial to 1000 r / min, then polishing the floor;

(4) polishing can not walk too fast, should be maintained at 50 m / min speed.

(5) to be overlap between lines 1 / 3, so as to avoid leakage of polishing.

Note:

A, Slate objects around the use of the machine;

B, you must use three power outlet, there must be ground or leakage protection, inspection machine, unplug after use;

Do you know what errors you stone care?

A: Do not free the wax. All types of wax on the market more than a water-based wax, stearic acid wax, wax oil, acrylic wax and so on. These are basically wax material containing acid and alkali. Not only will plug the pores of stone breath, but also the formation of wax coated with dust and dirt contamination, resulting in the phenomenon of the yellow stone surface. However, if the flow of pedestrians and goods, the place to be on the high frequency of wax, then consult a professional maintenance company to granite the use of wax and maintenance.

Second: Do not mess with the non-neutral detergent. For the sake of fast cleaning, general cleaning agents contain acid-base properties, it is unknown if prolonged use of detergent ingredients, will make the stone surface luster lost, and because of the residual non-neutral agent is the main cause of stone disease in the future produce .

III: long-term coverage is not carpet, debris. In order to maintain smooth breathing stone, should avoid carpet in the stone and debris covering the surface of the long-term, otherwise stone pores under the moisture can not evaporate. The stone due to excessive moisture, water content increased annoying stone disease arising from issues such as you must carpeting, piled debris, please do not forget to always change.

Fourth: To thoroughly clean clean. Whether in hard granite texture (hardness HRs88-1114-7) or the soft texture of the marble (hardness HRs46-773-5) are intolerant wind and sand and soil particles in the long-term devastation. Therefore, when the use of either electrostatic precipitator and dust mop thoroughly and cleaning work to do. Entry into the commercial space dust is best to place the pad, had brought the shoes involved in the sand filter is best started after the change into slippers home and reduce dust and sand the surface of the opportunity to wear the stone.

Five: To regular maintenance to maintain luster. Dust alone, cleaning can not be sustained to maintain the brilliant luster of stone refundable. Therefore, please be sure to regularly send professional companies to do maintenance and regeneration of gloss maintenance, such as: use of crystal liquid to the marble surface recrystallization, or use polishing powder for marble or granite surface regeneration gloss, or use polishing powder for marble or flowers regeneration gloss stone surface, or use the permeability of the protective agent such as gloss. Holding on to your stone can be as good as new.

Six: To immediately clear the pollution. All stones are pores with a natural, pollution (oil, tea, coffee, cola, soy sauce, ink, etc.) can easily penetrate into the stone house along the pores, the formation of unwanted stains, so be sure to select the good quality of stone facilities for special protective agent to prevent pollution source pollution in Stone. Impossible to know all the protectants are long-term denial of pollution hundred percent, so once back in the stone on the pollution sources must be immediately clear, to prevent infiltration of the pores within the stone.

Seven: To always maintain a dry and ventilated. Fear of too much humidity stone. Stone will produce water vapor hydration, hydrolysis and carbonate effects, resulting in water spots, bleaching, weathering, erosion, rust, yellow and other diseases, destroy the stone. Therefore, installation of a stone to be always kept dry and ventilated.

Eight: To regularly applied for protective treatment. Long life to protect the stone, blocking the penetration of water and pollution, must be on a regular basis (as the best quality of stone types and Protectant is a 1 - 3 years to do 1 - 2 in this treatment) facilities for protective treatment.

Protective agent must pay special attention to quality. After applications must be able to maintain the stone's Limestone and water resistance, stain resistance. Protective agent of unknown origin must not be used to avoid not only reach the protective effect, but increased the stone maintenance problems.
