Product Introduction
Hydroxypropyl methyl cellulose ether is a non-ionic cellulose ether made from high molecular material refined cotton by a series of etherification. It is an odorless, non-toxic white powder that swells into a clarified or slightly turbid colloidal solution in cold water. It has the characteristics of thickening, dispersion, emulsification, film formation, suspension, adsorption, surface activity, water retention and colloidal protection.
Hydroxypropyl methyl cellulose ether has the following properties:
A water retention - enhance water retention, improve cement, gypsum building materials dry too fast and insufficient moisture caused by poor hardening, cracking and other phenomena;
B Operability - enhance the plasticity of mortar and improve the operability of construction. Improve work efficiency;
C cohesiveness - due to the improved plasticity of mortar, it can better bond the substrate and the bonded material;
D Skid resistance - due to its thickening effect, it can prevent the slippage of mortar and adhesives during construction

1, YOUWEI cellulose ether in the application of ceramic tile glue system
Cement-based tile glue is a binder that binds tile glue to various substrates. Cellulose ether is an essential component in the formula of tile glue. Whether it is basic tile glue or high-quality tile glue, cellulose ether plays an important role.
The role of YOUWEI cellulose ether in tile glue:
1, cellulose ether can greatly improve the water retention capacity of ceramic tile binder, inhibit the significant loss of water to the highly absorbent ceramic tile and substrate, so that the ceramic tile glue has enough water for cement hydration hardening, thereby improving the bond strength.
2, extend the opening time to ensure that the water is firmly locked in a certain period of time, so that the tile glue keeps the surface wet for a long time, so that there is a long enough tile adjustment time.
3, anti-flow hanging, cellulose ether can provide a certain basic anti-slip property for tile glue, highly modified cellulose ether can significantly improve the anti-slip property of tile glue.
4, suitable wettability, so that the tile glue is easy to construction and effective bonding.
5, high temperature resistance, so that the viscosity of the tile glue remains stable at high temperatures. The viscosity of cellulose ether decreases gradually with the increase of temperature until it suddenly loses viscosity when it reaches a certain temperature. This process is reversible. The loss of viscosity means that the water retention of cellulose ether is reduced and the adjustment time is shortened.
YOUWEI cellulose recommended application in ceramic tile adhesive system products are UHK75M, UHK100M,UHK200M

2, tile sealant
The role of cellulose ether in tile caulking agent is to make the mortar evenly mixed, reduce bleeding, provide suitable construction consistency, reduce the risk of cracking, control the time of water loss and hardening, etc.
According to the construction environment and application of ceramic tile sealant, the selection of different types of cellulose ether can provide sufficient flexibility for the development of ceramic tile sealant products.
Product recommendation: YOUWEI cellulose 4000 or 7000 viscosity cellulose is generally recommended.

4. Putty powder
Putty is a thin layer, finely levelled batch-scrape plastering material that has been used in Asia for more than 30 years for the decoration of buildings
Both sexual and functional aspects play a very important role.
Putty is a thin layer, finely levelled batch-scrape plastering material that has been used in Asia for more than 30 years for the decoration of buildings
Both sexual and functional aspects play a very important role.
The interior and exterior walls of the building usually have three layers: substrate wall (brick, cut, concrete or leveling mortar), putty layer and coating layer, due to the difference in its deformation coefficient, when the ambient temperature changes, this will inevitably cause stress concentration, which requires the putty layer with its own elasticity to assume the task of eliminating stress concentration, so as to resist the base micro-cracking or coating layer peeling. The putty with good performance can not only make the wall achieve a smooth and seamless effect, but also make a variety of shapes to achieve the concept of the designer.
YOUWEI cellulose ether provides the putty with enough operable time, construction performance and water retention, and guarantees the putty against the base surface
Wettability, smoothness and recoating performance; The presence of cellulose ether makes the putty easy to be molded on various base surfaces
Reason.
