Chromium(III) sulfate usually refers to the inorganic compounds with the formula Cr2(SO4)3.x(H2O), where x can range from 0 to 18. Additionally, ill-defined but commercially important "basic chromium sulfates" are known. These salts are usually either violet or green solids that are soluble in water. It is commonly used in tanning leather. Basic Chrome Sulphate,Basic Chrome Sulfate for Tannery,Tanning Agent Basic Chrome Sulfate HENAN JINHE INDUSTRY CO.,LTD , https://www.hnchromiumoxidegreen.com
Eps cement sandwich panel lightweight external wall
Eps cement sandwich panel is a kind of lightweight energy saving wall material, which used cement calcium silicate or reinforced calcium silicate board as face panel, filled with cement, eps polystyrene foam particles and forming by one time compound.
Our advantage;
1. Energy saving and environment friendly
The EPS grain used in the core of the sandwich wall panel has good heat preservation function, can adjust the indoor temperature at a constant range, can save the energy used for air conditioning and heating. Victor stone EPS cement Sandwich wall panel is a perfect material to build thermally insulated wall.
2. Light weight and quakeproof
The weight of Victor stone EPS sandwich panel is only 1/10 of the traditional brick, it can allow you to build higher buildings and it will save 2/3 cost on foundation, beam, column structure. The panel-column connection has good Seismic performance, the index come up to 8.5. It can also apply to soft geology areas' buildings.
3. Fireproof
Tested by the National Research Center of Testing Techniques for Building Materials, Victor stone EPS Sandwich panels' fire resistance duration is 4 hours, Class A1 non-combustible.
4. Sound instulation
The EPS Polystyrene grain inside the core of the Victor stone Sandwich panel has good sound insulation and sound-absorption performance.
5. Waterproof and dampproof
Tests prove that the water containers made by Victor stone panel without plastering can hold water without leaking.
6. Increase the usable area, reduce the construction cost
Victor stone panel is thinner than the traditional blocks, it can increase the saleable area by 8~10%, save construction space and reduce the cost.
7short construction period, higt efficiency
Victor stone panels can be cut and drilled, uses dry way construction. Acheived the assembly installation, the speed is 6~7 times faster than the traditional wet way construction, greatly reduce the construction period.
Since 33% of the anion charges are due to hydroxy ions the basicity is 33% (but in tanning jargon it is known as 33% reduced). Products with higher basicities, e.g. 42% or 50% may be obtained by the addition of sodium carbonate, these are often used in combination with Sodium Formate. The sodium sulfate is often left in the technical product since it is inert with respect to the tanning process. It is important to fully reduce the hexavalent chromium to trivalent since the hexavalent is more likely to cause health problems for tanners and leather consumers.
