Specifications
Appearance: white or almost white fibrous or granular powder
Stability: solid is flammable and incompatible with strong oxidant.
Particle size; 100 mesh pass rate is greater than 98.5%; The passing rate of 80 meshes is 100%. The particle size of special specification is 40-60 meshes.
Carbonization temperature: 280-300 ℃
Apparent density: 0.25-0.70g/cm3 (usually about 0.5g/cm3), specific gravity 1.26-1.31.
Discoloration temperature: 190-200 ℃
Surface tension: 42-56dyne/cm in 2% aqueous solution
Solubility: soluble in water and some solvents, such as ethanol/water, propanol/water, etc. in proper proportion. The aqueous solution has surface activity. High transparency and stable
performance. The gel temperature of products of different specifications is different, and the solubility changes with viscosity. The lower the viscosity, the greater the solubility. The
performance of HPMC of different specifications is different, and the dissolution of HPMC in water is not affected by pH value.
With the decrease of methoxy content, the increase of gel point, the decrease of water solubility and the decrease of surface activity of HPMC.
HPMC also has the characteristics of thickening ability, salt resistance, low ash powder, pH stability, water retention, dimensional stability, excellent film-forming property, and extensive enzyme
resistance, dispersibility and cohesiveness.
It is 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
industry, ceramics, paper making, leather, medicine, food, cosmetics and other industries.
Main purpose
1. Construction industry: As a water retaining agent and retarder of cement mortar, the mortar has pumping property. Plaster mortar, gypsum material, putty powder or other building materials as
the adhesive to improve the smearability and prolong the operation time. It can be used to paste ceramic tile, marble, plastic decoration, paste reinforcing agent, and reduce cement consumption.
The water retention property of HPMC makes the slurry not crack due to too fast drying after application, and enhances the strength after hardening.
2. Ceramic manufacturing industry: widely used as adhesive in ceramic product manufacturing.
3. Paint industry: As a thickener, dispersant and stabilizer in the paint 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 mold release agent, softener, lubricant, etc.
6. PVC: used as dispersant in PVC production, it is the main auxiliary agent for suspension polymerization to prepare PVC.
7. Pharmaceutical industry: coating materials; Membrane material; Controlled speed polymer material of sustained release preparation; Stabilizer; Suspension aids; Tablet adhesive; Tackifier
8. Others: It is also widely used in leather, paper products, fruit and vegetable preservation and textile industries.
