Physical and chemical properties
Appearance: white or off-white fibrous or granular powder
Stability: The solid is flammable and incompatible with strong oxidants.
Particle size; 100 mesh pass rate is greater than 98.5%; 80 mesh pass rate is 100%. The particle size of special specifications is 40-60 mesh.
Carbonization temperature: 280-300℃
Apparent density: 0.25-0.70g/cm3 (usually around 0.5g/cm3), specific gravity 1.26-1.31.
Discoloration temperature: 190-200℃
Surface tension: 2% aqueous solution is 42-56dyne/cm
Solubility: soluble in water and some solvents, such as appropriate proportion of ethanol/water, propanol/water, etc. Aqueous solutions are surface active. High transparency and stable performance. Different specifications of products have different gel temperatures, and solubility changes with viscosity. The lower the viscosity, the greater the solubility. Different specifications of HPMC have different properties. The dissolution of HPMC in water is not affected by pH value.
With the decrease of methoxy group content, the increase of gel point, the decrease of water solubility, and the decrease of surface activity of HPMC.
HPMC also has thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film-forming properties, and a wide range of enzyme resistance, dispersibility and cohesiveness.
25kg/ drum or as per customers ' requirements .
Used as thickener, dispersant, binder, excipient, oil-resistant coating, filler, emulsifier and stabilizer in the textile industry. It is also widely used in synthetic resin, petrochemical, ceramics, paper, leather, medicine, food and cosmetics industries.
The main purpose
1. Construction industry: As a water-retaining agent and retarder for cement mortar, it makes the mortar pumpable. Used as a binder in plastering paste, gypsum, putty powder or other building materials to improve spreadability and prolong operation time. It is used as a paste for ceramic tile, marble, plastic decoration, as a paste enhancer, and it can also reduce the amount of cement. The water retention of HPMC can prevent the slurry from cracking due to drying too fast after application, and enhance the strength after hardening.
2. Ceramic manufacturing: widely used as a binder in the manufacture of ceramic products.
3. Coating industry: As a thickener, dispersant and stabilizer in the coating industry, it has good compatibility in water or organic solvents. as a paint remover.
4. Ink printing: as a thickener, dispersant and stabilizer in the ink industry, it has good compatibility in water or organic solvents.
5. Plastic: used as molding release agent, softener, lubricant, etc.
6. Polyvinyl chloride: It is used as a dispersant in the production of polyvinyl chloride, and it is the main auxiliary agent for the preparation of PVC by suspension polymerization.
7. Pharmaceutical industry: coating materials; film materials; rate-controlling polymer materials for sustained-release preparations; stabilizers; suspending agents; tablet binders; tackifiers
8. Others: It is also widely used in leather, paper product industry, fruit and vegetable preservation and textile industry.
