JF Hydroxypropyl Methyl Cellulose Powder 3912390000 Product Introduce:
 
Hydroxypropyl methylcellulose, also known as hypromellose, is a non-ionic cellulose mixed ether. It is a semi-synthetic, inactive, viscoelastic polymer, often used as a lubricant in ophthalmology, or as an excipient or excipient in stomatology.
It is soluble in water and some solvents, such as ethanol/water, propanol/water in appropriate proportions. The aqueous solution has surface activity. 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 performances. The dissolution of HPMC in water is not affected by pH.
 

 

 

 
Hydroxypropylmethylcellulose Function:
 
1. Construction industry: As a water-retaining agent and retarder of cement mortar, it makes the mortar pumpable. Used as a binder in plaster, plaster, putty powder or other building materials to improve spreadability and prolong operation time. It can be used to paste ceramic tiles, marble, plastic decoration, paste enhancer, and can also reduce the amount of cement. The water retention properties of HPMC prevent the slurry from cracking due to drying too fast after application, and enhance the strength after hardening.
2. Ceramic manufacturing industry: widely used as a binder in the manufacturing 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. Plastics: used as mold release agents, softeners, lubricants, etc.
6. Polyvinyl chloride: It is used as a dispersant in the production of polyvinyl chloride and 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; viscosity-increasing agents
8. Others: It is also widely used in leather, paper product industry, fruit and vegetable preservation and textile industry.
 
Hydroxypropylmethylcellulose Production Method:
 
The refined cotton cellulose is treated with alkaline solution at 35-40°C for half an hour, squeezed to crush the cellulose, and properly aged at 35°C, so that the average degree of polymerization of the obtained alkaline fiber is within the required range. Put the alkali fiber into the etherification kettle, add propylene oxide and methyl chloride successively, and etherify at 50-80℃ for 5h, the maximum pressure is about 1.8MPa. Then add proper amount of hydrochloric acid and oxalic acid, wash in 90°C hot water to increase the volume. Dehydrate and wash to neutral with a centrifuge. When the water content of the material is less than 60%, it is dried with hot air at 130°C until the water content is less than 5%, and finally smashed through a 20-mesh sieve to obtain the finished product.
