Hydroxypropyl methylcellulose is a nonionic cellulose ether prepared by a series of chemical processing using pure cotton as a raw material. Mainly used in the construction industry: water-resistant putty powder, putty paste, steel putty, paint glue and masonry mortar, dry powder insulation mortar and other dry powder building materials. Hydroxypropyl methylcellulose(HPMC) has good water retention [...]
The formula and process of the new gypsum mortar As we all know, the use of mortar insulation material in construction can improve the thermal insulation performance of external wall insulation layer, reduce indoor heat loss, and avoid the phenomenon of unequal heating among users, so it has been widely used in construction. Moreover, the [...]

Hydroxypropyl methylcellulose HPMC is refined from cotton by alkalization, and propylene oxide and methyl chloride are used as etherifying agents to form a nonionic cellulose mixed ether through a series of reactions. Hydroxypropyl methylcellulose is a nonionic cellulose ether that has a white appearance and is odorless and tasteless. The degree of substitution is generally [...]
Different dry powder mortar products have different performance requirements, and the dispersible polymer powder is required to provide suitable performance. Our products are mainly used in the combination of tile adhesive and exterior wall insulation system mortar and external wall flexible putty. 1 Dispersible polymer powder used in tile adhesive Tile adhesive is a cement-based [...]
The relationship between water retention and viscosity of hydroxypropyl methylcellulose is not a proportional relationship within a certain viscosity range, but also depends on the practical application of the product. Relatively speaking, when hydroxypropylmethylcellulose has a viscosity of more than 100,000, the difference in water retention between 100,000 viscosity and 200,000 viscosity is not large. [...]
Cellulose ether products applied to ceramic tile adhesive As a functional decorative material, ceramic tiles have been widely used all over the world. How to stick such durable materials to make them safe and durable has always been a concern. The emergence of tile adhesives To some extent, the reliability of the tile paste is [...]
Dry powder mortar, also known as mortar dry powder (mixed) material, refers to a granular or powdery mixture of fine aggregates, cemented materials and additives which are produced by professional manufacturers and dried and sieved in a certain proportion. It is transported to the construction site in the form of bags or bulk, and the [...]
Cellulose ether is a multi - purpose additive that can be used in cement products. Cellulose ether (abbreviated as CE, the abbreviation of Cellulose Ether) is formed by etherification of cellulose or one or more etherifying agents and dry grinding. Cellulose ethers can be divided into ionic and nonionic types. Among them, nonionic cellulose ethers [...]
The cellulose ether is a polymer compound having an ether structure made of cellulose, and each glucosyl ring in the cellulose macromolecule contains three hydroxyl groups, a primary hydroxyl group on the sixth carbon atom, and a second or three carbon atoms. The secondary hydroxyl group, the hydrogen in the hydroxyl group is substituted with [...]
Hydroxypropyl methylcellulose HPMC is a nonionic cellulose alkyl or hydroxyalkyl mixed ether obtained by a process of alkalizing, etherification, neutralization and water washing. Hydroxypropyl methylcellulose HPMC has good dispersing, emulsifying, thickening, bonding, water retention and gel retention properties, as well as adhesion, thickening and film forming properties. It can be widely used in petrochemical, construction, [...]
Hpmc can be used in putty powder,there are mainly four types of putty cracks. Insulation cracks: Generally, irregular cracks are common. It is caused by many reasons such as shrinkage deformation of benzene board, mesh cloth, mortar, and incorrect construction. The solution should be based on the size and distribution of the crack. If it [...]
The nature of cellulose Cellulose is a macromolecular polysaccharide composed of D-1 glucose, which is composed of β-1,4 glycosidic bonds, and has a molecular weight of about 50,000 to 2,500,000, which is equivalent to 300 to 15,000 glucosyl groups. The formula can be written as (C6H10O5)n. It is the main component of vascular plants, lichens [...]
1, methyl cellulose (MC) (1) Methylcellulose is soluble in cold water, and it is difficult to dissolve in hot water. The aqueous solution is very stable in the range of pH=3~12. It has good compatibility with starch, guar gum and many other surfactants. When the temperature reaches the gelation temperature, a gelation phenomenon occurs. After [...]
1. What is masonry mortar? What materials do masonry mortars consist of? A: The mortar that bonds bricks, stones, blocks, etc. into a masonry is called masonry mortar. The material composition of the masonry mortar: cement, other cementitious materials (such as lime paste, clay paste, hydroxypropyl methylcellulose, etc.), fine aggregate and water. 2. What should [...]
