Selection of HPMC viscosity when producing putty powder dry-mixed mortar?
Methyl cellulose MC and hydroxypropyl methyl cellulose (HPMC) have stable chemical properties, mildew resistance, and the best water retention effects, and are not affected by changes in pH value. It is not that the higher the viscosity, the better. The viscosity is inversely proportional to the ...Read more -
Classification and characteristics of construction grade cellulose
(Methyl chloride) (MC) Molecular formula \[C6H7O2(OH)3-h(OCH3)n1] x Refined cotton is treated with alkali, and methyl chloride is used as etherification agent. After a series of reactions, cellulose ether treatment is carried out. Generally, the degree of substitution is 1.6~2.0, and the degree o...Read more -
Can hydroxypropyl methylcellulose be used as construction glue?
First of all, the grade of construction glue should take into account the raw materials. The main reason for the layering of construction glue is the incompatibility between acrylic emulsion and hydroxypropyl methylcellulose (HPMC). Secondly, due to insufficient mixing time; there is also poor th...Read more -
