True mica powder and False mica powder? How to identify it?

Actually, it's easy to identify mica powder. There are three methods as follows:

1,We often receive the reaction from customers that the whiteness of mica powder is 90 or so. Under normal circumstances, the whiteness of mica powder is generally not high, only about 75%. If it's doped with other fillers such as calcium carbonate, talc and so on, whiteness will be greatly improved.

2,Mica powder is a sheet structure. Taking a beaker, adding 100ml  pure water and stirring with a glass rod, you can see the suspension of mica powder is very good. Other fillers' suspension including transparent powder, talc and calcium carbonate is belower than mica powder.

3,Painting a little on the wrist, there is a little pearl effect. MIca powder is widely used in cosmetics, coatings, plastics and rubber. If the purchase of mica powder's pearl effect is poor or without any pearlescent effect, this should be noted.

What is cobblestone and What is used for?

Pebbles as a kind of natural stone, taken from the crustal movement experienced by the thousands of years ago after an ancient riverbed gravel ridges produce mountains, experiencing the impact of flash floods, water removal process of continuous extrusion, friction. Tens of thousands of years of tremendous evolution, they tormented waves of water will sport collision friction is lost gravel irregular edges, and they are buried in silt an underground millions of years of silence. Cobblestone main chemical composition is silicon dioxide, followed by small amounts of iron oxides and trace amounts of manganese, copper, aluminum, magnesium and other elements and compounds. They themselves have different colors, such as crimson by iron, copper blue by purple by manganese, yellow translucent stone colloidal silica marrow, emerald color with green mineral, etc; Because these ions dissolved dioxide pigment silicon hydrothermal different in type and content, thus showing shades, shades of ever-changing colors, the pebbles showing a black, white, yellow, red, dark green, schungite other colors.

Cobblestone uses: Pebbles are widely used in public buildings, villas, garden buildings, paved roads, parks rockery, bonsai filling materials, garden art and other senior superstructure. Carry forward the ancient oriental culture, but also reflects the Western classical, elegant, return to basics style. Applies to: hotels, commercial buildings, exhibition halls, gardens, swimming pools, sidewalks, garden trails, walls and other landscape construction. Highlighting the harmony, upscale, elegant color.

Cobblestone also water purification, sewage treatment, electricity, garden items such projects to provide high-quality materials. Also ceramics, precision casting, paper, sprayed grinding, chemicals, silicon, national defense, such as raw and auxiliary materials.

Pebbles Material: 95% silica (SiO2).

Cobblestone Performance parameters: surface finish 98%, the compressive strength at 600 Kg / M2 more.

Rock slice with high quality

Natural rock film is an important raw material production of granite products such as paint, the ore by crushing, grinding, winnowing, grading, packaging, and other procedures from processing. Colors are black, yellow, green, brown, silver and so on. It is a kind of decorative materials, color retention, water resistance, simulation of strong and has excellent resistance groups and the cold, hot is not sticky, cold not crisp, rich colors, bright, plasticity, production lacquer, excellent partner granite paint, interior wall paint, three-dimensional strong new decorative materials.
Natural Flake color is very natural, and natural granite, marble color matching is harmonization. Section of natural granite, marble contains a small amount of natural rock piece.
Natural rock sheet has good abrasion resistance, mixed with the lacquer does not fade, not powder, with superior water resistance, weather resistance, with all kinds of water-based lacquer coating closely without affecting the original characteristics.
In recent years, the rapid development of the natural rock piece, because of its excellent performance, and lower prices, "lacquer, rock-chip paint, paint granite, artificial stone, decorative panels, interior and exterior paint, epoxy floor paint" and other products have been wide range of applications.
My company's main piece of rock color: gold, silver and white, black, green, red copper, brown. Products are graded and ungraded two standards.
Product Specifications Classification:
0.5-1mm (20-40 mesh), 1-2mm (12-20 mesh), 2-4mm (8-12 mesh), 4-6mm (3-5 mesh), 6-8mm (2-3 mesh)
Coloring Flake
Coloring sheet rock can compensate for the lack of natural rock chip color. Vivid colors, superior three-dimensional, aesthetics, environmental protection, and good color retention, water resistance, weather resistance. According to user needs, any color.
