With the rapid development of the global building decoration industry, quartz stone plate, as a new type of environmental protection material, has been widely used in the market because of its high hardness, wear resistance, strong pollution resistance and other characteristics. This paper will deeply explore the production process of quartz stone plate and its environmental protection trend, to provide a valuable reference for people inside and outside the industry.

Overview of the production process of quartz stone plate

Quartz stone plate is a new type of stone synthesized by more than 90% quartz crystal plus resin and other trace elements. The production process mainly includes raw material procurement, material selection, batching, mixing, cloth, vacuum high-frequency vibration plate, heating curing, fixed thickness, polishing, inspection and packaging and other links.

1. Raw material procurement

The main raw materials of quartz stone plate include resin, quartz sand, glass, curing agent and auxiliary agent. The procurement of these raw materials needs strict control to ensure the quality and stability of raw materials.

2. Material selection and ingredients

The material selection process is mainly through manual selection or color sorting machine, iron removal equipment to remove impurities in the quartz sand, iron filings, etc., to ensure the purity of the quartz stone plate. The blending is to load the screened raw materials into the mixer in a certain proportion and mix them fully to eliminate the problems of material color difference and uneven particles.

3. Stir with fabric

The mixing process is to grind and disperse the pigment with resin, quartz sand, quartz powder and additives for full mixing to ensure the uniform combination of materials. The cloth is to mix the mixed material through the conveyor belt, into the cloth car, and then the material is evenly distributed into the mold by the cloth car.

4. Vacuum high frequency vibration pressure plate

After the cloth is completed, the material is transported to the vacuum vibration press, and the vibration is pressed under the vacuum condition of close to -0.1MPa to ensure that the table is dense without pores. In 2010, Saiyuan world's first air spring pressurized press, the structure is more simple and reasonable, greatly reducing mechanical failure. The main parts of the press are cast steel parts, which can effectively improve the mechanical strength and service life. The vacuum box of the press adopts a special structure, greatly shortening the vacuum time, stable and efficient operation of the equipment, effectively ensuring the flatness of the plate, uniform texture, high density, high hardness, no porosity.

5. Heat curing

After the pressing is completed, the raw embryo plate enters the curing furnace for curing under the condition of 80-90℃ to improve the strength of the plate and prevent deformation.

6. Thickness and polishing

The cured sheet is treated with a fixed thickness after cooling, and then it is continuously polished from coarse to fine through more than 20 processes to ensure the gloss of the surface of the sheet. Saiyuan automatic polishing machine is equipped with electronic late abrasive detection system, which can automatically alarm and remind the operator to replace the abrasive when the corresponding abrasive is used up. The intelligent degree is high, the large-size touch screen is used, and the parameter adjustment is more convenient.

7. Inspection and packaging

Finally, the appearance, size and partial performance of the plate are inspected according to quality standards to prevent unqualified products from flowing out. The qualified products are sprayed, coated with protective film and packaged, and sold all over the country.
