Audited Supplier Hydroxypropyl methylcellulose, also known as hypromellose, cellulose ether HPMC. In the coating, printing and dyeing industry, it has the characteristics of toughness and flexibility.
About coating printing and dyeing process:
The coating process is a process of spraying liquid on the substrate.
Coating:
A method of coating a paste polymer, molten polymer or polymer melt on paper, cloth, or plastic film to prepare a composite material (film).
Use:
Building anti-corrosion, insulation, decoration, etc.
Many advantages of adding HPMC to the coating process:
01.
HPMC can be mixed with commonly used textile sizing agents and modifiers, so that it can be used in warp sizing and fabric glazing trees.
02.
HPMC can also be dissolved in the dispersant of polyethylene powder and can be used for the thermoplastic setting of fabrics.
03.
Treating polyester fiber with HPMC light alkali aqueous solution, after a short time of heat treatment (>120ºC and <polyester melting point), can give the fabric a silky feel.

What are the main raw materials of HPMC?
Answer: The main raw materials are refined cotton, methyl chloride, and propylene oxide, followed by other raw materials, such as caustic soda, acid, toluene, isopropanol and so on.
Features.
01.
After adding HPMC, the raw material is easy and smooth when hanging, can be molded at one time, and has plasticity.
02.
After adding HPMC, increase the bonding strength between the gypsum base and the base layer.
03.
After adding HPMC, excellent wet bonding performance, reducing floor dust.
04.
After HPMC is added, the settling time of gypsum is reduced, the drying shrinkage rate is reduced, and the wall is not easy to hollow and crack.
Application test of HPMC in construction gypsum:
1. Strength test:
After testing, gypsum-based hydroxypropyl methylcellulose has excellent tensile bonding strength and compressive strength.
2. Coating rate test:
The gypsum base coating rate refers to the result obtained by measuring the wet bulk density of the gypsum base. One ton of gypsum-based products constructs a wall area of 10mm thick.
The use of hydroxypropyl methylcellulose products can greatly increase the coating rate, can cover more areas, can reduce labor intensity, save materials, and improve economic benefits.
Learn more about the role of HPMC.
01.
HPMC has stable performance and strong water absorption, which can effectively control water content and moisture.
02.
Keep the base material in a wet state for a long time.
03.
It has a larger hydration volume in colloidal materials and is used as a thickener.
04.
The polymer can affect the particle flocculation state of the base material, thereby affecting the structure and rheology of the base material.
