Product Details

‌HPMC's role in bonding mortar mainly includes thickening, water retention, bonding and film formation. ‌HPMC, or hydroxypropyl methylcellulose, is a polymer compound widely used in the building materials industry and plays an important role in bonding mortar. Specifically, the role of HPMC includes:

‌Thickening effect‌: HPMC has a long molecular chain and can form a three-dimensional network structure in water, thereby increasing the viscosity of the mortar. This helps to improve the working performance of the mortar, making it more convenient in transportation and construction, while effectively preventing water evaporation.

‌Water retention effect‌: HPMC has excellent water retention properties and can effectively delay the setting time of the mortar. This helps prevent shrinkage cracks in the mortar during transportation and construction and improves the durability of the mortar‌.

‌Bonding effect‌: HPMC has a good bonding effect and can improve the bonding between the mortar and the base layer. This helps prevent the mortar from falling off during construction and improves the adhesion of the mortar.

‌Film-forming effect‌: The film formed by HPMC has good toughness and durability, which can improve the waterproof performance and durability of the mortar.

In summary, HPMC significantly improves the performance of the bonding mortar through its unique physical and chemical properties, and improves the construction effect and durability of the material.

FAQ

What is the main use of 1-Hydroxypropyl methylcellulose (HPMC)?

HPMC is widely used in industries such as construction materials, coatings, synthetic resins, ceramics, pharmaceuticals, food, textiles, agriculture, cosmetics, and tobacco. HPMC can be classified into architectural grade, food grade, and pharmaceutical grade based on its application. Currently, most domestically produced HPMC falls under the architectural grade category. In the architectural grade, a large amount of HPMC is used in putty powder, accounting for approximately 90% of its usage, while the rest is used in cement mortar and adhesives.
