Hydroxypropyl methyl cellulose functions and parameters: instead of a characteristic group characteristics of the so-called groups, mainly refers to hydroxypropyl methylcellulose in place group volume or size. Instead of the base of the volume, the more easy to make macromolecular chains separated by spacer molecules increases, hydrogen reduction, instead of dissolving the desired reduced accordingly. On the contrary, if the volume of the smaller group HPMC instead, want to give the desired solubility, the demand for more instead, that the higher the substitution degree hydroxypropyl methylcellulose demand. Because cellulose occurs when replaced along with Vice reaction occurs and follow DS increased, Vice reaction also increases, and therefore a corresponding increase in cost of repercussions reagents. Therefore, that the use of a large group of hydroxypropyl methylcellulose instead of to some cheap. However, it should be noted that in place of the low, easy to cause instead of uniform. Hydroxypropyl methyl cellulose, hydroxypropyl methyl cellulose is modified About a promising commodity, hydroxypropyl methyl cellulose water heating pasting monotonous damage sieved to obtain a variety of degenerative hydroxypropyl methyl cellulose, such as hydroxypropylmethyl cellulose, dextrin, hydroxypropylmethyl cellulose acidified, basified hydroxypropylmethyl cellulose, hydroxypropylmethyl cellulose oxidized, cationic hydroxypropyl methyl cellulose, hydroxypropyl methyl cellulose esterification, carboxymethyl of hydroxypropyl methyl cellulose, hydroxypropyl methyl cellulose and cross-linked graft copolymer hydroxypropyl methyl cellulose, etc., to habits It is not the same need for the construction of the construction process. Hydroxypropyl methyl cellulose can be applied to the food industry: food thickener and stable agents, children nutritious food materials; feed industry: As fish feed binder. Hydroxypropyl methyl cellulose and useful features: held hydroxypropyl methyl cellulose certain amount of mixing water have some time to continue to meet the advance of cement hydration, traveling mortar adhesion to the substrate in the mortar. Water retention function to a large extent the impact of mortar dissolved by the time, hydroxypropyl methyl cellulose thinner to dissolve faster on water conservation function also faster. Mechanization construction, because time reasons, the selection of hydroxypropyl methyl cellulose powder must be finer. About manual plastering, fine powder on it. Hydroxypropyl methyl cellulose in water solubility and temperature are dependent on the degree of etherification, outside temperature add, reduce water retention; the higher the degree of etherification, hydroxypropyl methyl cellulose ether water retention as possible.
