The basic method of preparation of artificial marble

Synthetic stone (artificial marble) used in the production of more classes of calcium minerals are calcite, quartz stone (artificial quartz stone) is the mineral silica, both of vacuum, vibration, and three mechanical compression force and the adhesive force of the chemical synthesis of condensation products for the architectural decoration. With the choice of the crystal mineral, stone size gradation, color matching, fabric mode, secondary staining and molding changes in the way, can be synthesized to produce quality products and variety of color changes. Currently, the industry of stone to say that "there is a market and due to profit", quartz stone is a "less hardness and density."

In response, this paper folding barrier and vibration is the basic method of production of synthetic stone point, the specific materials used to the large size of mineral crystals, glass beads and expanded in three areas of nano materials, vibration and electromagnetic vibration of layered The formation mechanism and preparation of synthetic stone and preparation texture hole program were discussed.

    At present, most of the production of synthetic stone artificial stone enterprises in the production process for the jade, rare granite, marble, beautiful pattern, color and beautiful mineral crystal river pebbles, large flowers are still using the existing products of the post Stone molding process, the limitations of its stone size can produce color concrete under the effect of the class. Glass beads and nano-materials have been widely used in construction and other fields, will be applied to the wall stone decoration of its production expansion may be valuable to try. Large size glass beads of crystal light minerals and wall panels forming the two products are not hard-pressed without the technical requirements, can use two kinds of forces and vibration and vacuum pumping system for vacuum and release the vacuum force to separate need to study the problem of its formation. Stacked stone base is derived from the ancient method of aggregation, its deep knowledge and understanding, and then with the current process of vibration dense abstract comparison, different but not difficult to find the combined and have the same density with the truth. Synthetic stone patterns existing configuration confined within the mixing in the twin-shaft mixer color process method, whether it is the spray after the mixing, or the reunification of the two kinds of color material mixing body, although the effect of a certain color , but its color has not extended fabric link is extremely favorable for further study.

    First, the large size of the base using the combination of mineral crystals

    The existing vertical twin-shaft mixer with cloth bucket machine stone structure, only appropriate to choose the maximum size of stone 12cm, the dosage can only be limited to about 40%, and therefore constitute a barrier stack of stones close pattern is not possible. For has through sexual and hidden flash and natural texture Crystalline crystal mineral size Only and its has fragmentation large and mix closer their mutual or artistic until tie high ornamental and market value. The texture also has a block in their degree and form can be displayed when, if hard to be broken into small pieces is actually a man-made destruction.

    Barrier layer vibration and the process by cascading approach is to suppress the overall mixing and strong links to cancel the two molding process, only the lower part of vacuum pumping system and the level of vibration and some of its blocks to complete the cycle of the molding. Its technical characteristics are: the choice of base material to be transparent or the basis for the selection of good-looking, and its fragmentation is generally more than 20cm, and hand apparatus for its rough shaping, during which the body can be expected carry out its part of the artistic carving and modeling ; ingredients are filled between the base material and binder, can be about 10% of the unsaturated resin and stone powder mixture is thick and shaped, and filled with jade and other high-grade stone, the formula can still be used to man-made with jade paste into the body, it fills the gap with the same transparency; as the base material of the barrier stack of mineral crystals, subject to the laws of formal beauty, the general, plastic, choice and assembly of the layer stack technique, during which a balanced changes in virtual and real, scattered and overall contact order; layer of vacuum pumping system and the lower part of vibration to time with the cooperation relations between the two, especially the release of the vacuum generated by the impact of unexpected density effects arising . Colorful pebbles is a very good base material, it moves through rivers, erosion and wear and tear of having "old" style, and then with the same rounded body is a small sand particles (Yellow sand) with the use of layered vibration molding process can produce simple results.

    Second, the vibration of quartz stone to further explore forming

    Mineral quartz (SiO2) often develop into single crystal and the formation of druse, containing small dispersed gaseous or liquid substance is milky white, shiny glass crystal face, fracture for the oil sheen, no cleavage, hardness 7, the relative density of 2.65. Way in its use of compression-based broken into small particles, because of its significant edges and creating a greater coefficient of friction.

That no cleavage and a greater coefficient of friction of stone tablets and powder mixture formed so dense point is to overcome the friction coefficient and the formation of closely stacked micro base. The current structure of sheet molding machine is characterized by: a pressure trough (head) vertical interspersed within the structure of the vacuum hood is bound to bear the resulting negative pressure vacuum compression force of about 500KN; vacuum cover and the pressure head form of the vertical sliding Even in the 5 +5 group of vibrators is not easy to pressure head torsion vibration; vibration still use a larger cylinder or hydraulic pressing force to suppress the formation of the exciting force is much smaller than the cylinder pressure and vacuum pull and three of the transmission system and a serious weight problem.

    Theories we can see from the vibration, the vibrating force and the eccentric rotational speed proportional to the square of its amplitude with the pressure head and the weight of the transmission system and the applied pressure is inversely proportional. It can be seen with the cylinder pressure is a conceptual error suppression methods. The lack of amplitude and swing, and then in frequently difficult to improve conditions, to make it to 2.5g/cm3 quartz plate forming the density is not possible. Is reluctant to use this yet to be improved reliability and performance of the quartz plate production machine, must pay 2 percent more than the amount of molding resin material body is often formed into a group of problems, the distributor is difficult to uniaxial These resin particles crushing dough mixing, it can only use the screen and the hand were the crushing treatment. In fact, the existence of blocks forming most of the excitation frequency is also the problem of insufficient, 4200r/min generated by the maximum speed is very strongly felt. Fortunately, forming blocks can increase the pressure of the process of rubbing back and forth movements to feed the body with extra calcium powder with a liquid way to be filled.

    Circular rubbing pressure mode of vibration characteristics of electromagnetic vibration. With six groups and coordination of special magnet structure and enhance its vibration and pressure with a compression spring (board) composed of vibration system, in its 0-f0 of the frequency adjustment to its current six-beat pulse cycle control, can pressure to quickly produce a 6 × f0 (50Hz) frequency superposition, and in its high-frequency vibration to quickly swing the same time, it is fast and without rubbing hard-pressed pressure molding the vibration mode.
