physical and chemical properties:
1, appearance: white or white powder.
2, particle size of 100 mesh; pass rate is larger than 98.5%; 80 orders through rate of more than 100%.
3, carbonization temperature: 280-300 degrees
4, apparent density: 0.25-0.70/cm3 (usually around 0.5g/cm3), the proportion of 1.26-1.31.
5, color temperature: 190-200 degrees
6: 2%, the surface tension of water solution is 42-56dyn/cm.
7, soluble in water and some solvents, such as appropriate proportion of ethanol / water, isopropanol / water, three chlorine ethane. Aqueous solution with surface activity. High transparency, stable performance, products of different specifications of different gel temperature, solubility with viscosity change, lower viscosity, the greater the solubility, there are certain differences in different specifications of HPMC performance, HPMC is not affected by the pH effect of solubility in water.
8, HPMC with the methoxyl content decreased, gel point increased, water solubility decreased, surface activity also decreased.
9, HPMC is thickening ability, salt resistance and low ash powder, PH stability, water retention, dimensional stability, excellent film-forming property, and a wide range of enzyme resistance, dispersion and adhesion characteristics.
main purposes:
This product is an industrial grade HPMC, mainly for the purpose of dispersant in the production of PVC suspension polymerization, preparation of PVC main auxiliaries. In addition, in other petrochemical, paint, building materials, paint remover, agricultural chemicals, textile printing and dyeing, printing ink, paper, ceramics, cosmetics and other products for the production of thickener, stabilizer, emulsifier, excipient, water retaining agent, film-forming agent. The application of synthetic resin in hand, we can make the products with regular particles, loose, as the proportion of suitable features such as excellent processing performance, thus basically replaced gelatin and polyvinyl alcohol as dispersing agent. In addition, in the construction industry in the construction process, mainly used for walls, stucco, caulking etc. in the mechanical construction; especially in decorative construction, used as a paste ceramic tile, marble, plastic decoration, high bonding strength, but also can reduce the dosage of cement. Used for thickening agent in the coating industry, the layer is bright and smooth, off powder, improve leveling performance etc..
Application:
1. It can be used in Cosmetics.
2. It can be used in Pharmaceuticals.
dissolution method:
1, take the required amount of hot water into the container is heated to 85 DEG C, gradually add the product slowly stirring, cellulose was floating in the water, but gradually dispersed, forming a homogeneous slurry under stirring cooling solution.
2, or 1/3 or 2/3 will be heated to above 85---, adding cellulose, get hot water slurry, cold water, then add the remaining amount to keep stirring, cooling the mixture into.
packing and storage precautions:
Carton packaging, lined with polyethylene film inside the barrel net weight: 25kg. in storage and transportation to prevent rain and moisture.
All Key Manufacturers and Suppliers of Baoji Guokang have routine inspections to ensure they are in compliance with the standards set in place during the original Supplier Assessment Inspection.
