Latest hydroxypropyl methyl cellulose ether manufacturers offer

Hydroxypropyl methylcellulose function and parameters: whether the use of HPMC, viscosity measurement, still functions are soluble in water to show later carried out. And as many commodities demand may also increase the demand on water it is not the same. Not the same as the viscosity of hydroxypropyl methylcellulose dissolved in water the speed respectively, the case of water-soluble ensuing not the same, the higher the viscosity the higher the concentration the higher the viscosity, the concentration of even minor changes viscosity changes also make immeasurable. The hydroxypropyl methyl cellulose dissolved in water in some function back is that it can not be ignored as the effect of increasing agent, such as its water retention in the mortar. Hydroxypropyl methyl cellulose, methyl cellulose Introduction (MC), hydroxypropyl methyl cellulose (HPMC), hydroxyethyl methyl cellulose (HEMC) is a natural polymer materials (refined cotton) for information After a series of chemical processing and the obtained non-ionic cellulose ethers, they have a water-soluble, water retention, nonionic, PH value stable, surface active, reversible condensate temperature, glue, adhesive film-forming properties, lubricity , mildew resistance and other features. It is widely used in construction materials, paints, synthetic resin, ceramics, pharmaceuticals, video, textiles, agriculture, makeup, tobacco and other operations. Hydroxypropyl methyl cellulose and useful features: 1, while adhering mortar activity is (165 ± 5) mm, hydroxypropyl methyl cellulose polymer powder dosage add significantly increased water-cement ratio of mortar, And when HEMC polymer content of not more than 3%, with the addition of its content, the gradual reduction of water-cement ratio, when the polymer content of 4% to 7%, the modified mortar foundation in the same water-cement ratio. 2, hydroxypropyl methyl cellulose polymer powder dosage at the 0 to 0.7%, significantly delayed the time modified cement mortar cohesion; while the polymer content of less than 4%, with the addition of its content, moment slightly modified mortar cohesion extends content at 4% -7%, modified mortar cohesion moments foundation unchanged. 3, re-mixed, when the polymer dosage constant, M add content can significantly extend the time modified mortar cohesion. And when hydroxyethyl cellulose content unchanged, not when the polymer content, from the moment the effect of extending the mortar cohesion; polymer content is large, compared with polymer modified mortar cohesion moments when a slightly smaller dosage shortened.
