hpmc manufacturer-What items can 100,000 viscosity hydroxypropyl methylcellulose be used for?

Dry quickly. This is mainly the amount of ash calcium powder (too large, can appropriately reduce the amount of ash calcium powder in the putty formula) and the water retention rate of HPMC, and the drying degree of the wall.

In the putty powder, HPMC plays three roles of thickening, water retention and construction. Do not participate in any reaction.

Methyl cellulose ether can make the ash (mortar) slurry material obtain suitable water retention and consistency, and effectively improve the workability of the plastering material; at the same time, it can gradually release the water over a long period of time, thereby Ensure the combination of ash (mortar) and base.

In the recent research on the composition of the internal wall insulation mortar, it is not difficult to find that there is a kind of hpmc that is very common in our lives. Let’s not look at its economic benefits for the time being. First of all, this type of raw material for internal wall insulation mortar has the effect of strengthening the product. So what is hpmc and what is the working principle of product response:

The viscosity of aqueous solution of hydroxypropyl methyl cellulose is mainly affected by the degree of product polymerization, concentration of product in aqueous solution, shear rate and solution temperature. The viscosity of aqueous solution increases with the increase of product polymerization degree and concentration, and decreases with the increase of shear rate and solution temperature.Salt and safe insecticides can also be added to obtain better viscosity characteristics and application performance. Users should consider the actual situation and economy to choose hydroxypropyl methyl cellulose viscosity specifications and addition.

HPMC is a type of non-ionic cellulose ether, white powder appearance, odorless and tasteless, soluble in water and most polar organic solvents. Its water solution has a surface activity, high transparency, stable performance.

HPMC is odorless, tasteless,non-toxic cellulose ethers produce from natural high molecular cellulose through series of chemical processing and achieved.It is white powder with good water solubility. It has thickening, adhesion ,dispersing, emulsifying, film, suspended, adsorption, gel, and protective colloid properties of surface activity and maintain moisture function properties ect.

Cellulose HPMC is widely used in construction materials, coatings, synthetic resins, ceramics, medicine, food, textile, agriculture, cosmetics, tobacco and other industries. HPMC can be divided into construction grade, food grade and medical grade according to its usage.
