Hydroxypropyl methylcellulose is often used in various industries. Although many people do not understand it very well, it does affect various industries. In the construction process of the construction industry, it is usually mainly used for wall building and stucco decoration, Caulking and other mechanical construction fields, especially in decorative construction, it is often used for tiling, marble, and some plastic decorations. It has a high degree of adhesion and can reduce the amount of cement used. It is used in the coating industry, mainly used as a thickener, can make the layer fine and bright, not easy to remove powder, improve leveling performance, etc., especially for the application in the field of building self-leveling mortar.

The self-leveling sand award is mainly a special dry-mixed mortar product with leveling and self-compacting functions. Its self-compacting and self-leveling capabilities are very important for achieving a seamless and smooth ground layer. For good self-leveling products, first It must have suitable operational performance, and be able to maintain its overall leveling performance and self-healing ability within the construction time. In this way, this requires the mortar to fully ensure its stability and uniformity within this period of time. Secondly, the mortar must have a certain strength, which includes the bearing capacity and the bonding force to the base surface. These are the basic conditions for the normal application of self-leveling materials, and the realization of these properties of self-leveling requires hydroxypropyl the addition of methyl cellulose ether can thicken and increase viscosity, and also has the characteristics of high water retention and prolonging the construction time.

The higher the viscosity of hydroxypropyl methylcellulose, the better the viscosity of the modified cement-based material, but if the viscosity is too high, it will affect the fluidity and operability of the material. In addition, the thickening effect of hydroxypropyl methylcellulose can also increase the water demand of cement-based materials, thereby increasing the yield of mortar. Self-leveling mortar and self-compacting concrete, which require high fluidity, require low viscosity of hydroxypropyl methylcellulose. The low-viscosity cellulose ether can play a good suspending effect, prevent the slurry from settling, and also has a bleeding function, which can ensure that it will not affect the flow effect of the self-leveling mortar material, is easy to construct, and has high water retention The characteristics can make the surface effect after leveling better, reduce the shrinkage of mortar, and avoid peeling cracks and so on.

Hydroxypropyl methylcellulose is widely used in various building materials. When used in self-leveling mortar, it has the following characteristics:

1. High water retention performance can prolong the operation time of self-leveling mortar, improve the durability of mortar, increase its bonding strength, and excellent wet bonding performance can reduce landing ash.

2. Strong compatibility, suitable for all kinds of building materials, self-leveling mortar, reducing sinking time, reducing its drying shrinkage rate, and avoiding problems such as cracking and drumming of walls and floors.

3. Prevent bleeding, it can play a better role in the suspension, prevent the slurry from sedimentation and better bleeding performance.

4. Maintain good flow performance, the low viscosity of hydroxypropyl methylcellulose will not affect the flow of slurry, easy construction, specific good water retention performance, can produce a good surface effect after self-leveling, and avoid cracking in the case of drums, the stable bonding performance of cellulose ether fully guarantees good fluidity and self-leveling ability. Controlling the water retention rate can make it solidify quickly and reduce shrinkage and cracking.
