Product Description
Physical and chemical properties:
1. Appearance: White or off-white power.
2. Particle: 100 mesh passing than 98.5%, More than 80 mesh by 100%.
3. Carbonization temperature: 280-300 degrees Celsius.
4. Apparent density: 0.25-0.70 / cm3 (usually in 0.5 g/cm3), a proportion of 1.26-1.31.
5. Color temperature: 190-200 º C
6. Surface tension: 2% peroxide solutions are 42-56dyn/cm
7. Dissolves in the water and the partial resolvers, such as appropriate amount of ethanol / water, two chlorine ethane etc...Aqueous solution has surface activity. The transparency is high, performance is steady, different products of the specification congeal glue temperature differently. Solubility with viscosity, change, 15th, the viscosity is the lower, the solubility is the heavier, different performance their, HPMC of specification, have certain difference, HPMC dissolving among water, influenced by pH.
8. HPMC reduces, congeals with first oxygen base content the glue is lighted and risen, solubility of water drops, the surface activity drops too.
9. HPMC also increases thick ability, able to bear salt low gray powder, pH stability, water-retaining property, becoming membrane, and able to bear characteristics such as enzyme nature, dispersiveness and cohesiveness, etc. Ing extensive fine.
Main use:
Product this industry magnitudes of HPMC, main use whether polyvinyl chloride make dispersant produce, suspend and get main auxiliary which prepares PVC together. In addition, in other petrochemical industry, coating, building materials, divided by paint pharmaceutical, agricultural chemicals, do thickening agent, stabilizer, emulsifier, excipient, water retaining agent, becoming pharmaceutical of membrane etc. In production such as printing ink, textile printing and dyeing, pottery, papermaking, cosmetics. The application in synthetic resin, but make the products obtained have particles whole, loose and looking at the specific gravity suitably rules, the characteristic such as being of good performance of processing, thus basically replaced gelatin and polyvinyl alcohol and made dispersants. In addition, while the industry of the building constructs, used mainly for building a wall, the plaster is glossed over, the filleting is waited for mechanizedly while constructing; Especially in ornamental construction, it is ornamental to use as pasting ceramic tile, marble, plastics, it is high to paste the intensity, can also reduce cement consumption. Used and made thickening agent in the coating trade, can enable and pursue layer bright and finely and smoothly, does not take off the powder, improve and flow flat performance, etc...Uses in whitewashing the gypsum, the caking gypsum, the caulked joint gypsum, in the water resistant putty the branch obviously enhances its water retention property, the cohesional strength and so on
Dissolving methods:
1. Fetch the required hot water, put into container and heat the above, join this product under stiring slowly gradually, the cellulose originally floats on the surface of water, but dispersed gradually, form the even slurry, cool solutions under stiring.
2. Either heat the hot water of 1/3 or 2/3 to 85 ---The above, add the cellulose, get the thick liquid material of hot water, and then add the cold water of surplus quantity, keep stiring, cool the mixture got.
3. After surface treatment's product, may join in cold water under the agitation to dissolve directly, after the available ammonia water or the tax cut adjust pH-10, the product will dissolve rapidly, forms the solution.
