The importance of hydroxypropyl methylcellulose in building dry powder additives

Speaking of hydroxypropyl methylcellulose, perhaps the general public do not know what it is, but for the construction industry, most of the first-line construction workers are quite clear.

The main function of hydroxypropyl methyl cellulose in dry building powder additives is to thicken and retain water. Although the cellulose added in dry building powder is not a lot, it only accounts for about four thousandths, but its role is comparative Importantly, the thickening and water-retaining effects of hydroxypropyl methylcellulose can enable workers to construct well during construction, and at the same time can appropriately increase the tensile strength and shear strength, greatly improve the construction effect, and enhance Improve work efficiency.
