1. The quality of hydroxypropyl methylcellulose produced in horizontal and vertical kettles

Soluble in water and some organic solvents

It is soluble in cold water, and its maximum concentration is only determined by viscosity. The solubility changes with viscosity. The lower the viscosity, the greater the solubility.

Regarding the gel temperature of hydroxypropyl methyl cellulose HPMC, many users seldom pay attention to the problem of hydroxypropyl methyl cellulose gel temperature. Nowadays, hydroxypropyl methyl cellulose is generally distinguished by viscosity, but for For some special environments and special industries, it is not enough to reflect the viscosity of the product. The following briefly introduces the gel temperature of hydroxypropyl methylcellulose.

The role of hydroxypropyl methyl cellulose in the construction industry The role of hydroxypropyl methyl cellulose in the dispersion and mixing of building materials 1. The dry blend formula containing hydroxypropyl methyl cellulose can be easily mixed with water .

Hydroxypropyl Methylcellulose and Methylcellulose are water-soluble ethers with excellent performance, suitable for building coatings as retarders, water-retaining agents, thickeners and binders. HPMC and MC have already been used in plaster, cement, lime and mortar.

The instant hydroxypropyl methylcellulose is designed by SLEO chemical to be converted into water-based or water-based products. The surface of the cellulose fan is treated with glyoxal at a certain temperature and PH value. The surface of the gold star is treated by this treatment. The hydroxypropyl methyl cellulose is dispersed in the cold water of ZTE without swelling and viscosity, which delays the swelling.

Cement mortar: improve the dispersibility of cement and sand, greatly improve the plasticity and water retention of mortar, and improve the strength of cement.
HPMC used in Tile adhesive: to improve the plasticity, water retention and glue relay of ceramic tile mortar, to prevent powder.
Coating of fireproof materials such as asbestos: as suspension agent, fluidity improver, and improved adhesive relay on basement.

The production of oil with hydroxypropyl methylcellulose as raw material substrate can realize the utilization of whole sugar, improve the utilization rate of raw materials, reduce the substrate residue in fermentation broth, and reduce the cost of wastewater treatment. This characteristic of hydroxypropyl methylcellulose is conducive to the optimization of batch, feed-batch and continuous fermentation processes, avoiding a series of problems such as controlling medium composition and dilution rate, and is also conducive to regulating the fermentation process.

Hydroxypropyl methyl cellulose in dry mortar (mortar), the addition of cellulose ether is very low, but it can significantly improve the performance of wet mortar. Mortar is the main additive that affects construction performance. The redispersible latex powder product is a water-soluble white or almost white flowable powder, a copolymer of ethylene and vinyl acetate, and polyvinyl alcohol as a protective colloid.
