HPMC for Tile Adhesive contains cement, sand, limestone and other additives to increase the adhesion of ceramic tile. Tile adhesive is a new type of modern decorative material used to paste ceramic tiles, face tiles, floor tiles and other decorative materials. There are many kinds of additives in ceramic tile adhesive, but usually cellulose ether additives are added to ceramic tile adhesive to improve water retention, thickening effect and open time.
Before using HPMC tile adhesive, prepare the adhesive powder with water at the ratio of 1:0.25-0.3. After the adhesive is completely dry and stirred well, it can be constructed, and the position of the tiles can be adjusted within the permitted operation time (filled in about 24 hours, and heavy objects should be prevented from pressing on the surface of the tiles within 24 hours).
HPMC (new generation methylcellulose) is a commonly used adhesive additive and is widely evaluated in tile adhesives. The following are several major applications of HPMC in ceramic tile adhesives:
1. Moisture conditioner: HPMC has excellent water solubility and water retention properties, which can adjust the moisture content in tile adhesive and control the viscosity and fluidity of the adhesive. By adjusting the amount of HPMC added, the appropriate viscosity of the tile adhesive can be achieved, making it easy to construct and apply.
2. Improve bond strength: HPMC can increase the bonding strength and adhesion of tile adhesive. It forms a sticky film in the glue, which can effectively bond the contact surface between the ceramic tile and the base layer, and provides good bonding performance to prevent the ceramic tile from hollowing or falling off.
3. Slip resistance: Because HPMC has higher viscosity and adhesion, it can increase slip resistance in tile adhesives and provide better construction performance. This ensures the tiles remain stable during installation, reducing slippage and the need for adjustments.
4. Crack resistance: HPMC can also increase the flexibility and elasticity of tile adhesive and improve its crack resistance. This is important to prevent the tile adhesive from cracking and breaking under stress or temperature changes, ensuring the durability and durability of the tile installation.
HPMC cellulose has a variety of properties such as thickening, water retention, dispersion, emulsification, film-forming, adhesion, gelling, adsorption, etc. HPMC has good effect in tile adhesion, which can improve the anti-slip, water retention, open time, viscosity and strength of the tile adhesive. Due to the high water resistance of hydroxypropylmethylcellulose, there is no need to pre-soak or wet the tiles and substrates, which significantly improves bond strength. The slurry can be applied for a longer period of time with easy and uniform application. Fine texture and good anti-slip performance.HPMC has the functions of thickening, bonding, dispersing, emulsifying, PH stabilizing, film-forming, suspending, adsorption, gelation, surface activation, water retention and protection of colloid.
1. Enhance the water retention properties, prolong the working time.
2. Improve the bonding strength of tile adhesive.
3. Improve the flexibility and deformation ability of caulking material.
4. It can enhance the anti-flowing and hanging property of tile adhesive.
5, good bonding strength, regardless of thickness, low shrinkage, tiles will not crack or fall under pressure.
6. The mortar has better ductility and flexibility, making the construction easier and the work more efficient.
In general, the application of HPMC for tile adhesives mainly includes adjusting moisture content, improving bonding strength, increasing slip resistance and improving crack resistance. It plays an important functional and technological role in the ceramic tile installation process, improving the performance and construction quality of ceramic tile adhesive.
