Key Points For Production Of Best Quartz Stone Slabs

The selection of raw materials is one of the key points for the production of the best quartz stone slabs. In order to produce qualified and durable quartz stone slabs, Before purchasing the raw materials, try to find a supplier with a good reputation and credit. Quartz stone slab production requires raw materials that include resin, quartz sand powder, glass, color paste, curing agent, and coupling agent.

Resin:

Full name: unsaturated polyester resin;
Polymer solid content: over 65%;
Resin viscosity: 850–1200 MPa (adjust resin viscosity according to temperature);
Resin heating peak temperature: :160 °C to 170 °C;
Appearance: special resin for quartz stone, colorless, no impurities, translucent liquid.

Production of quartz stone slabs: key points is the raw and auxiliary materials.

Quartz Powder:

Fineness requirement: 240–400 mesh;
Whiteness requirements: 95 degrees above(Use resin and quartz powder to make a paste; requiring white, translucent, black, yellow is unqualified.)
Sio2 content: 98% above.

Quartz Sand:

Uniform particles, no impurities, no foreign bodies, and can not contain iron;
4–120 mesh particles and no wind-fossil particles.

Glasses:

Transparent glass, requiring no shredded paper, debris or other miscellaneous glass particles;
Mirror glass. It is required not to fade, gray and white bottoms can be uniform.

Color Paste:

It is required to use the color paste directly, because the color powder can not be completely dispersed, which will lead to a slab color difference.

Curing Agent:

Medium-temperature curing agent: tert-butyl diethyl caproate peroxide (OT);
Room temperature initiator: methyl ethyl ketone peroxide accelerator: cobalt naphthenate
