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 popülerle?tirilmesi
Hidroksipropil metilselüloz HPMC, bir dizi kimyasal i?lem yoluyla do?al polimer malzeme selülozdan yap?lan iyonik olmayan bir selüloz eterdir. So?uk suda ?i?en, berrak veya hafif puslu bir kolloidal ??zeltiye d?nü?en kokusuz, tats?z ve toksik olmayan beyaz bir tozdur. Kal?nla?t?rma, ba?lama, da??...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 -
Introduction to Hydroxypropyl Methyl Cellulose
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 -
Talking about the application of hydroxypropyl methyl cellulose in machine spray mortar?
With the wide use of mortar, the quality and stability of mortar can be well guaranteed. However, since the dry-mixed mortar is directly processed and produced by the factory, the price will be higher in terms of raw materials. If we continue to use manual plastering on site, it will not be compe...Read more -
The importance of hydroxypropyl methylcellulose (HPMC) for water retention in mortar!
Why is the requirement for water retention in mortar so high, and what are the outstanding advantages of mortar with good water retention? Let me introduce to you the importance of water retention in mortar! The need for water retention Water retention of mortar refers to the ability of mortar to...Read more -
The role of hydroxyethyl cellulose (HEC) in coatings!
Hydroxyethyl cellulose (HEC), a white or light yellow, odorless, non-toxic fibrous or powdery solid, prepared by etherification of alkaline cellulose and ethylene oxide (or chlorohydrin), belonging to the genus Nonionic soluble cellulose ethers. Because HEC has good properties of thickening, susp...Read more -
Choose hydroxypropyl methylcellulose, you know?
What is the difference between hydroxypropyl methylcellulose (HPMC) with or without S? 1. HPMC is divided into instant type and rapid dispersion type HPMC fast dispersing type is suffixed with the letter S. During the production process, glyoxal should be added. HPMC instant type does not add any...Read more -
Classification and use of hydroxypropyl methylcellulose
Low viscosity: 400 is mainly used for self-leveling mortar, but generally imported. Reason: The viscosity is low, although the water retention is poor, but the leveling is good, and the mortar density is high. Medium and low viscosity: 20000-40000 is mainly used for tile adhesive, caulking agent,...Read more -
