Artificial colors of sand

Artificial colors of sand is the color selection of quartz sand processing through multi-channel processes rounded, rounded particles after chemical treatment and then by high temperature sintering. Artificial sand make up the color of natural sand color is not bright color and less variety and other shortcomings, solid color, durable. Granule color multi-stage filter, in order to ensure uniform grading, packing density increases, anti-stress.
Features:
1, a variety of particle size uniform, rounded particles, can be arbitrarily graded
2, rich colors, beautiful lasting.
3, with a variety of resins and insoluble.
performance:
1, roundness: round-shaped particles of 6%, 4% shaped particles
2, hardness: Mineral Mohs hardness: 6.5 to 7.0
3, specific gravity: true specific gravity: 2650 kg / m3; bulk specific gravity: 1524 ~ 1588 kg / m3
4, cleanliness: impurities ≤1%
5, porosity: ≤23.8%
6, Acid: 10% HCl solution soak 8 hours, no change in color
7, Alkali resistance: 10% NaOH solution soak 8 hours, no change in color
8, resistance to chemical solvents: xylene solution soak for 24 hours, no change in color
9, hot water resistance: 90 ℃ hot water soak 8 hours, no change in color
use:
Artificial colors of sand is mainly used for various types of color epoxy floor, lacquer, all kinds of architectural coatings, sandstone plate, ABS modified felt, waterproofing membrane, handicrafts and so on, it colorful, weather resistance, wear acid base, non-slip, seamless, high-grade appearance.

Influence of sepiolite fiber on insulation materials properties

Fire engineering often add a lot of additives to improve the insulation materials properties, to improve the construction and use quality of insulation material. Sepiolite fiber is a commonly used additive.
A small amount of sepiolite fiber has little effect on the thermal conductivity. The thermal conductivity without sepiolite fiber is 0.078 W/MK. When the content of sepiolite fiber is 6%, the thermal conductivity increases to 0.079 W/MK. But when the content is more than 6%, the thermal conductivity increases more. This is because the sepiolite fiber content is too large, the fresh slurry fluidity decreases too much, resulting in glass beads in the mixing process easily broken, so that the volume of inorganic insulation mortar shrinkage, closed voids reduce , thereby increasing the Thermal Conductivity.

Compressive and flexural strength and  bond strength of insulation materials all increased with the increasing of sepiolite fiber content. And the strengthening effect of sepiolite fiber on flexural strength and bond strength is better than compressive strength. When the content of sepiolite fiber is 2%, the flexural strength increases by 33.9%, the bond strength increases by 9.1%, and the compressive strength increases by only 2.9%. hen the content is 6%, the flexural strength increases 62.3% and the compressive strength increases 18.2%. This is because that sepiolite fibers can be scattered in the clutter of insulation materials, playing as a "skeleton" support, increase the compressive strength of insulation materials and bond strength. The addition of fiber is particularly effective in bending and bonding strength, which can significantly improve the anti-cracking properties of insulation materials. 

In the construction, In the construction, the number of additives is small but the impact on the material is significant. the use of appropriate additives to improve the quality of construction can achieve a multiplier effect.

What is Kaolin?

Kaolin also called china clay, soft white clay that is an essential ingredient in the manufacture of china and percelain and is widely used in the making of paper, rubber, paint, and many other products. Kaolin is named after the hill in China (Kao-ling) from which it was mined for centuries. Samples of kaolin were first sent to Europe by a French Jesuit missionary around 1700 as examples of the materials used by the Chinese in the manufacture of porcelain.

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.
