Quick Drying Silica Sol For Precision Casting

Supplier From China
Nov-23-16

Model: JW-FD30A

Details:
SIO2 Content: 28-30%
NA2O content: 0.5%
viscosiry: 10
PH value: 9.0-10.5
SP.GR: 1.19-1.21
Particle size(nm): 10-15

Characteristic:
1. Increase the elasticity of coating on the surface with wet strength, reduce or eliminate the surface dry too fast and the cause of crack, peeling of casting structure quality problems.
2. Excellent dehydration performance, easy to form a uniform drying coating.
3. Increase the adhesion of colloidal silica and refractory powder, bond strength and increase pulp and refractory aggregate coated with sex, increase the shell strength, reduce the coating and the shell thickness.
4. Improve the shell permeability. Volatilization roasting make polymer, form fine exhaust passage inside the shell, increase permeability, reduce casting defects such as misrun of thin water even.
5. Shell low residual strength. Polymer volatilization reduced shell, residual strength Yi Qing shell.
6. Low requirements for environment is conducive to the stability of the production process and quality.
7. Rapid drying, the drying time between the layers 1 ~ 2 h.
8. Water-based, environmentally friendly products.
9. Stable performance, long shelf life (1 year).
Application:
Precision casting Industry

We are glad to propose 500 MT of stain less steel mill scale.
Mill scale is formed on the outer surfaces during by the hot rolling lamination of stainless-steel products.

At a visual inspection the material is a hard brittle sand and is mainly composed of iron oxides, mostly ferric, and is bluish black in colour, but it also contains considerable alloying elements such as chromium and nickel.

The recovery ratio after melting in furnace for the most valuable alloy elements is:
- Ni: 3.5 - 4.5%
- Cr: 6-8%


From the chemical and physical analysis performed on the scrap, and according to the European environmental rules, the material has been classified as a special non dangerous waste, listed in green list. In particular the mill scale can be classified as follows:

Waste code: 10 02 10

The material is stored on cemented flooring, and it can be loaded loose in tipper trucks or containers.

Chemical analysis of the material is available on request.

Commodity: Synthetic Cryolite
Formula: Na3AlF6
M.W.: 209.95

Properties: The product is a white crystalline powder or a sandy-size granularity, and a pinkish crystalline powder or a sandy-size granularity as well. Sp.gr.2.953.01g/cm3, melting point about 1000centigrade, specific heat 1.056j/gcentigradeat 18100centigrade. Its slightly soluble in water, but insoluble in anhydrous hydrogen fluoride. The content of its crystal water will be decreased while the increasing of the molecular ratio, therefore its loss on ignition will be also decreased while the increasing of the molecular ratio. After the paste of synthetic cryolite with different molecular ratio dehydrates, the loss on ignition at 800centigrade will appear 10.34%, 6.22% and 2.56% when the molecular ratio reaches 1.74, 2.14 and 2.63 reactively.

Commodity: Calcium chloride
Molecular formula CaCl2
H.S code 28272000

Product feature
Calcium chloride is an inorganic salt, which exists as solid or liquid. Solid calcium chloride is a white, crystal substance in the form of flake, granule, pellet or powder. With different crystallized water contents, it can be dihydrate or anhydrous.

Liquid calcium chloride is a colorless, clear solution. As calcium chloride has such properties as quick dissolving, exothermic ability, attracting moisture from the air and surroundings, dissolving at very low temperature,
