Special specifications particle size of 40 to 60 mesh. 3, carbonization temperature: 280-300 ℃ 4, depending on the density: 0.25-0.70g / cm (typically 0.5g / cm or so), the proportion of 1.26-1.31. 5, color temperature: 190-200 ℃ 6, the surface tension: 2% aqueous solution of 42-56dyn / cm 7, Solubility: soluble in water and some of the solvent, such as an appropriate proportion of ethanol / water, propanol / water. Aqueous solution with surfactant. High transparency, stable performance, different specifications of different gelling temperature, solubility with viscosity changes, the lower the viscosity, the greater the solubility of different performance specifications HPMC have some differences, HPMC dissolved in water pH value is not affected. 8, HPMC with a methoxy content reduction, the gel point increases, the water solubility of the drop, a surfactant is also decreased. 9, HPMC also has thickening ability, low ash, salt, pH stability, retention, dimensional stability, excellent film-forming properties, as well as a wide range of anti-enzyme, dispersion and adhesion characteristics. Formula: C12H20O10 Molecular Weight: 324.2848 CAS no: 9004-65 Introduction 1. Purpose Construction: aquasorb as cement mortar, mortar with a retarder pumping. In the plaster slurry, gypsum material, putty powder or other building materials as a binder to improve spreadability and extend the operating time. Used as a stick tiles, marble, plastic decoration, paste enhancer can also reduce the amount of cement. HPMC water retention will not make the paste dries too fast and cracks in the painting, and enhance strength after hardening. 2. ceramics industry: the manufacture of ceramic products are widely used as a binder. 3. paint industry: in the paint industry as thickeners, dispersants and stabilizers in water or an organic solvent having good compatibility. As a paint remover. 4. Printing ink: the ink industry as thickeners, dispersants and stabilizers in water or an organic solvent having good compatibility. 5. Plastic: for forming mold release agents, softeners, lubricants. 6. PVC: PVC production as dispersant, suspension polymerization system was prepared mainly of PVC additives. 7. Other: This product is also widely used in leather, paper products, fresh fruits and vegetables, and textiles. 8. pharmaceutical industry: the coating material; membranes; sustained-release formulations speed control polymer material; stabilizer; suspending agent; tablet binder; thickening agent
