Making artificial stone how to do it
Mixing of raw materials
① artificial marble raw material mixing of various materials according to the proportion of the design directly into the vacuum mixer, and then the binder (cement or resin) pre-mixed into a paste, into the vacuum mixer stir and vacuum.
② people make granite raw material mixing two different colors of raw materials were put into the two groups of planetary mixer, pre-mixing evenly, and then the two colors of the material scattered on the rotating disc. Forming a clear two layers, and then a certain height drop unloading to the conveyor belt, resulting in the appropriate mixture of two materials, and finally sent to the vacuum mixer to mix a vacuum can be.
In order to realistic imitation of natural granite, but also in the mix with several colors of stone.
Raw material preparation and ingredients
① the stone block, gravel, coarse marble powder by design ratio device hopper, weighing the belt with weighing ingredients.
② the marble powder, fine powder stored in the vertical warehouse, to the provisions of the quality sent to the mixer.
③ white cement stored in a vertical warehouse, said the scheduled quality, open the gate into the mixer.
④ resin into the resin tank, the use of quantitative injection into the mixer.
⑤ catalyst, accelerator, defoamer were stored in stainless steel containers, according to the need to use a quantitative pump into the proportion of the mixer.
⑥ pigment with a special container by design crushing, weighing and pre-mixing into the mixer.
⑦ If you use cement as a binder should be prepared when the water, electronic control of pneumatic valve control of water (the rest with ① ~ ⑥).
Processing of sheet metal
The method and natural stone processing methods, also need to go through cutting, grinding, polishing, protection and other processes. In order to improve the quality of synthetic stone, the need to cut the board surface of the mortar, in order to achieve smooth and smooth, mainly in a mixture of resin and calcium powder on the stone surface, it is important to note that the difference between the color as much as possible, after hardening Polished can be, the final cut edge, chamfer, acceptance.
Synthetic stone
In a vacuum under pressure, vibration, so that the air as much as possible to discharge, and then into the mold pressure, vibration, vacuum in the vacuum chamber, after a certain period of time, mold car out of the vacuum chamber, for conservation. Resin (organic synthetic stone) generally need to conservation 7d, cement (inorganic synthetic stone) need to conservation 7d (20 ℃); natural conservation needs 15d. After the demolition of the mold, sawing processing.
