The preferred high-quality cellulose glue manufacturer

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 characteristics and use: in the mortar for participating hydroxypropyl methylcellulose, so fresh mortar introduced a certain amount of thin, uniform, stable bubbles, because the balls effect, the mortar has excellent workability, cut shortening and cracking mortar and mortar travel yield. Hydroxypropyl methyl cellulose have cited qigong used, adding hydroxypropyl methylcellulose hours, thinking content, viscosity (viscosity is too high will affect the construction), cited gas. Suitable selection of different mortar hydroxypropylmethylcellulose.
