Factory-made mortars have been mostly implemented as masonry renderings, fixing tiles, self-levelling floors and so on. When mortar is applied on substrate, water may be absorbed by the substrate. This phenomenon can induce insufficient hydration of cement, and thus decrease mechanical properties of the mortar.
Read MoreThe HPMC mainly plays a role in water retention and thickening, able to effectively improve the bond force and sag resistance of slurry.
Read MoreThere are different types of viscometers used to measure the viscosity of a cellulose ether solution. The widely adopted viscometers are: HoppIer falling ball viscometer, Haake rotation Rheometer and Brookfield rotation viscometer. The viscometer commonly used in China is NDJ series.
Read MoreHydroxy Propyl Methyl Cellulose (HPMC) helps to significantly improve the water-holding capacity of mortar. Just a low level of hydroxy propyl methyl cellulose addition can lead to a significant improvement on the water retention rate of the mortar.

1. Hydroxy Propyl Methyl Cellulose can provide the viscosity and can be used as anti-settling additives.
Read MoreWith the rapid development of the construction industry, people have increasing demands for new building materials. Due to the increase in people’s awareness of environmental protection and the continuous improvement of construction efficiency,
Read MoreThe water putty is divided into two kinds: dry powder putty and putty paste. In the two kinds of putty, the modified methyl cellulose and hydroxypropyl methyl cellulose are generally chosen for use, and the viscosity is the most suitable between 30000-60000cps.
Read MoreIn the dry-mixed mortar, the cellulose ether plays a role in such aspects as water retention, thickening and improving construction performance. Good water retention can avoid the sugaring, dusting and strength decrease of mortar resulting from water shortage and incomplete cement hydration;
Read MoreCellulose ethers are currently the commonly used polymer admixtures of the cement mortar used in construction. Cellulose ethers can be fully dispersed in water to form a transparent viscous liquid. With a small amount (the mass percentage of less than 1%) added to the cement,
