HPMC manufacturer-How to Choose Hydroxypropyl Methylcellulose for Construction Glue?
The problem of building glue stratification is a problem encountered by customers. The construction glue stratification should consider the problem of raw materials. The main reason for building glue stratification is the incompatibility of hydroxypropyl methyl cellulose (HPMC) and polyvinyl alcohol (PVA) Caused; Secondly because the stirring time is not enough; and the thickening performance of the construction glue is not good.
In construction glue, instant hydroxypropyl methyl cellulose HPMC must be used, because hydroxypropyl methyl cellulose HPMC is only dispersed in water without real dissolution. About 6-7 minutes, the viscosity of the liquid gradually increased, forming a transparent viscous colloid. Hot-dissolving products, when encountering cold water, can be quickly dispersed in hot water and disappear in hot water. When the temperature drops to a certain temperature, the viscosity slowly appears until a transparent viscous colloid is formed. The recommended dosage of hydroxypropyl methylcellulose HPMC in construction glue is 2-4kg.
SLEOCHEM HPMC, also instant hydroxypropyl methylcellulose HPMC has stable chemical properties, mildew resistance and good water retention in construction glue, and is not affected by pH changes. The viscosity can be used from 100,000 S to 200,000 S. However, in production, the higher the viscosity, the better. The viscosity is inversely proportional to the bond strength. The higher the viscosity, the smaller the strength. Generally, the viscosity of 200,000 S is appropriate.
