Performance of construction grade HPMC powder in construction industry:
1) Construction grade HPMC powder is an important component of building mortar. Its high water holding capacity can make the cement fully hydrated, significantly increase the bond strength, properly improve the tensile elongation and shear strength, greatly improve the construction effect and work efficiency.
2) Construction grade HPMC powder mainly plays the role of water retention, adhesion and lubrication in putty powder to avoid cracks and dehydration caused by rapid water loss, enhance the adhesion of putty, reduce the sagging phenomenon in construction, and make the construction more smooth.
3) Construction grade HPMC powder plays the role of water retaining and lubrication in gypsum series products. At the same time, it has a certain retarding effect, which solves the problems of bulging and initial strength not reaching in the construction process, and can extend the working time.
4) Construction grade HPMC powder is mainly used as thickener in the interfacial agent, which can improve the tensile strength and shear strength, improve the surface coating, enhance the adhesion and bond strength.
5) Construction grade HPMC powder has the function of bonding and increasing the strength of the external thermal insulation mortar, which makes the mortar easier to be coated, improves the work efficiency, and has the function of anti vertical flow. The higher water retention performance can extend the working time of the mortar, improve the anti shrinkage and anti cracking performance, improve the surface quality, and improve the bonding strength.
