The necessity of adding hydroxypropyl methylcellulose (HPMC) to mortar and gypsum-based products!
In cement mortar and gypsum-based slurry, hydroxypropyl methylcellulose mainly plays the role of water retention and thickening, which can effectively improve the cohesion and sag resistance of the slurry. Factors such as air temperature, temperature and wind pressure will affect the evaporation ...Read more -
The main uses and differences of hydroxypropyl methylcellulose HPMC and hydroxyethyl cellulose HEC
There are industrial monosodium glutamate, carboxymethyl cellulose, hydroxypropyl methyl cellulose, and hydroxyethyl cellulose, which are the most used. Among the three types of cellulose, the most difficult to distinguish is hydroxypropyl methylcellulose and hydroxyethyl cellulose. Let us distin...Read more -
Hydroxypropyl methylcellulose use classification?
Hydroxypropyl methylcellulose is divided into two types: ordinary hot-melt type and cold-water instant type. Hydroxypropyl methylcellulose uses 1. Gypsum series In gypsum series products, cellulose ethers are mainly used to retain water and increase smoothness. Together they provide some relief. ...Read more -
Hydroxypropyl methylcellulose HPMC
Hydroxypropyl methyl cellulose, also known as hypromellose, cellulose hydroxypropyl methyl ether, is obtained by selecting highly pure cotton cellulose as raw material and specially etherified under alkaline conditions. Widely used in construction, chemical, pharmaceutical and other industries. c...Read more -
What factors affect the water retention of hydroxypropyl methylcellulose
The higher the viscosity of hydroxypropyl methylcellulose, the better the water retention performance. Viscosity is an important parameter of HPMC performance. At present, different HPMC manufacturers use different methods and instruments to measure the viscosity of HPMC. The main methods are Haa...Read more -
Popularization of hydroxypropyl methylcellulose HPMC knowledge
Hydroxypropyl methylcellulose HPMC is a non-ionic cellulose ether made from natural polymer material cellulose through a series of chemical processing. They are an odorless, tasteless and nontoxic white powder that swells in cold water to a clear or slightly hazy colloidal solution. It has the pr...Read more -
Hidroksipropil metilselüloz HPMC bilgisinin popülerleştirilmesi
Hidroksipropil metilselüloz HPMC, bir dizi kimyasal işlem yoluyla doğal polimer malzeme selülozdan yapılan iyonik olmayan bir selüloz eterdir. Soğuk suda şişen, berrak veya hafif puslu bir kolloidal çözeltiye dönüşen kokusuz, tatsız ve toksik olmayan beyaz bir tozdur. Kalınlaştırma, bağlama, dağı...Read more -
The synthetic method of hydroxypropyl methylcellulose
Generally, in the synthesis of hydroxypropyl methylcellulose, the refined cotton cellulose is treated with alkali solution at 35-40°C for half an hour, squeezed, the cellulose is pulverized, and appropriately aged at 35°C, so that the obtained alkali fibers are averagely polymerized degree is wit...Read more -

Appearance and properties: white or off-white fibrous or granular powder Density: 1.39 g/cm3 Solubility: almost insoluble in absolute ethanol, ether, acetone; swelling into a clear or slightly cloudy colloidal solution in cold water Stability: The solid is flammable and incompatible with strong o...Read more -
Factors Affecting the Viscosity Production of Hydroxypropyl Methylcellulose
The viscosity index of hydroxypropyl methylcellulose is a very important index. The viscosity does not represent the purity. The viscosity of cellulose HPMC depends on the production process. Different use environments should choose cellulose HPMC with different viscosities, not the higher the vi...Read more -
Relationship between Viscosity and Temperature of Hydroxypropyl Methylcellulose (HPMC)
(1) Determination of viscosity: The dried product is prepared into an aqueous solution with a weight concentration of 2 °C, and is measured by an NDJ-1 type rotational viscometer; (2) The appearance of the product is powder, and the instant product is suffixed with “s” in the brand na...Read more
