In the use of construction materials, Hydroxypropyl Methylcellulose is a common additive for construction materials. Hydroxypropyl methylcellulose is widely used in industry and has different types, hydroxypropyl methylcellulose can be divided into cold water instant type and hot melt type.
HPMC Cellulose can be used in putty powder, mortar, liquid glue, liquid paint and daily chemical products. Hot melt HPMC is usually used in dry powder products and mixed directly with dry powder for uniform application, such as putty powder and mortar. Hydroxypropyl methylcellulose can be widely used to improve the performance of cement, gypsum and other hydrated building materials. In cement-based mortars, it improves water retention, extends correction time and open time, and reduces flow suspension.
Hydroxypropyl methylcellulose can be used in the mixing and construction of building materials, and dry-mix formulations can be mixed quickly with water to quickly obtain the desired consistency. Cellulose ethers dissolve more quickly and without agglomeration. Propyl methyl cellulose can be mixed with dry powders in construction materials. It has cold water dispersion properties that suspend solid particles well and make the mixture finer and more homogeneous. In addition, it enhances lubricity and plasticity, increases workability, and makes product construction easier. Enhanced water retention and longer working time help prevent vertical flow of mortar and tiles, prolong cooling time and improve work efficiency.
Hydroxypropyl methylcellulose improves the bond strength of tile adhesive, improves the crack resistance of mortar and board joints, not only improves the air content in mortar, but also greatly reduces the possibility of cracking, it also improves the appearance of the product and can enhance the anti-sagging property of tile adhesive.
We believe that the role of hydroxypropyl methyl cellulose in construction materials has been understood, in addition the company also provides Construction Hpmc, if you need, please feel free to contact us
