Hydroxypropyl methylcellulose HPMC manufacturers solve the problem of lamination of building glue

The lamination of building glue is a problem that customers often encounter. To solve the problem of building glue lamination, the first thing is to consider the problem of raw materials. The main reason of building glue lamination is the incompatibility of polyvinyl alcohol (PVA) and hydroxypropyl methyl cellulose (HPMC); the second is that the mixing time is not enough; and the thickening performance of construction glue is not good.

In the construction glue, it is necessary to use the instant hydroxypropyl methyl cellulose (HPMC), because the instant hydroxypropyl methyl cellulose (HPMC) is only dispersed in the water, and there is no real dissolution. It's about two minutes. It's going to be a transparent, viscous liquid. Heat soluble products, when meeting cold water, can disperse rapidly in hot water and disappear in hot water. When the temperature drops to a certain temperature, the viscosity slowly appears until transparent viscous colloid is formed. The recommended tonnage of HPMC in building glue is 2-4kg.

Hydroxypropyl methyl cellulose (HPMC) has stable chemical properties, good mildew proof and water retention effect in building glue, and is not affected by pH value change. The viscosity can be used from 100000 s to 200000 s. However, in production, the higher the viscosity is, the better it is, and the viscosity is inversely proportional to the bonding strength. The higher the viscosity is, the smaller the strength is. Generally, the viscosity of 100000 s is appropriate.
