Hypromellose-masonry mortar enhances the adhesion to the surface of the masonry and the water holding capacity, thus increasing the strength of the mortar. Improved lubricity and plasticity leading to improved construction performance, easier application, time savings, and improved cost-effectiveness.
Hypromellose-good water retention of sheet joint fillers can prolong cooling time and improve work efficiency. High lubricity makes application easier and smoother. Also improve the anti-shrinkage and anti-cracking, effectively improve the surface quality. Provides a smooth and uniform texture, and makes the bonding surface stronger.
Hypromellose-cement-based plastering improves uniformity, makes plastering easier to apply, and improves resistance to vertical flow. Enhance fluidity and pumpability to improve efficiency. The utility model has the advantages of high water retention, prolonging the working time of the mortar, improving the working efficiency, and contributing to the formation of high mechanical strength of the mortar during the solidification period. In addition, the air infiltration can be controlled, thus eliminating the micro-cracks of the coating, forming an ideal smooth surface.
HPMC-- plaster, plaster and gypsum products
Improve uniformity, make the plaster more easily coated, while improving the ability to resist vertical flow to enhance liquidity and pumping. So as to improve work efficiency. It also has the advantage of high water retention, can extend the working time of mortar, and produce high mechanical strength during solidification. By controlling the consistency of the mortar uniform, the formation of high-quality surface coating.
Hypromellose -- water-based paints and paint removers extend the shelf life by preventing solid precipitation. It is compatible with other components and has high biostability. The rapid dissolution without agglomerates helps to simplify the mixing process. Provides favourable mobility, including low splashing and good leveling to ensure good Surface finish and prevent paint drooping. Enhance the viscosity of water-based paint remover and organic solvent paint remover, so that paint remover will not flow out of the surface of the workpiece.
Hypromellose-ceramic tile adhesives make it easy to mix dry mix ingredients without creating clumps, thus saving working time and improving workability and reducing costs by making it faster and more efficient to apply. The efficiency of sticking bricks is improved by cooling time. Achieve adhesion effect. Self-leveling hypromellose provide viscosity and can be used as an anti-sedimentation additive. Improve mobility and pumpability, thereby improving the efficiency of floor laying. Control water retention, thereby greatly reducing cracking and shrinkage.
Hypromellose-formed concrete sheets enhance the processability of the extruded product, providing high bond strength and lubricity. Improve wet strength and sheet adhesion after extrusion.
Factors that affect water retention of hypromellose HPMC products
The water retention of hypromellose HPMC products is often affected by the following factors:
1.Cellulose ether HPMC homogeneously reacted with HPMC, methoxy, hydroxypropyl homogeneously distributed, high water retention rate.
2.Cellulose ether HPMC thermogel temperature, thermogel temperature, high water retention rate, on the contrary, low water retention rate.
3.When the viscosity of cellulose ether HPMC increased, the water retention rate also increased, and when the viscosity reached a certain degree, the water retention rate increased gradually.
4.The more the cellulose ether HPMC was added, the higher the water-holding rate was, and the better the water-holding effect was. In the range of 0.25-0.6% , the water retention rate increased rapidly with the increase of the addition amount.
