Construction chemical knowledge and information

Hydroxypropyl methyl cellulose in the construction of building materials lax and mixing 1. Hydroxypropyl methyl cellulose dry mix formulations can be easily mixed with water.2. Be nimble to get the required consistency.3. Cellulose ether dissolves more quickly and without lumps.Hydroxypropyl methyl

Causes of exterior wall insulation falling off:1. Basic structural factors.At the joints between concrete beams and columns and masonry, the thermal insulation damage caused by masonry deformation is easy to occur in the outer wall of frame structure.The scaffold hole is not built solid, forming the

HPMC can be divided into instant type and hot soluble type, instant type products, in cold water quickly dispersed, disappear in the water, at this time the liquid has no viscosity, because HPMC is just dispersed in the water, no real solution.About 2 minutes, the viscosity of the liquid gradually i

Two dissolution methods of HPMCPowder mixing method: the HPMC powder and a large number of other powdery material ingredients, fully mixed with a blender, after adding water to dissolve, then the HPMC can be dissolved at this time, without agglomeration, because each tiny little corner, only a littl

Hydroxypropyl methyl cellulose (HPMC)Hydroxypropyl methyl cellulose is in recent years production, dosage are rapidly increasing cellulose varieties.It is made of refined cotton after alkali treatment, with propylene oxide and chloroform as etherifying agent, through a series of reactions and made o
