China HPMC Manufacturer

Hydroxypropyl Methylcellulose (HPMC) is a versatile polymer derived from cellulose. It is a non-ionic, water-soluble compound that is commonly used in various industries, including construction, pharmaceuticals, cosmetics, and food.

Function of HPMC: HPMC serves several functions due to its unique properties. Some key functions of HPMC include:

1. Thickening Agent: HPMC can increase the viscosity of liquid formulations, making it useful in applications where thickening is required.

2. Water Retention: HPMC has excellent water retention capabilities, allowing it to hold water in construction materials for an extended period. This property is crucial in preventing premature drying and improving workability.

3. Binding Agent: HPMC acts as a binder in construction materials, providing cohesion and enhancing the strength of the final product.

4. Film Formation: HPMC can form a thin, flexible film when dried. This property is utilized in coatings and adhesives.

5. Improved Workability: By controlling the hydration rate of cement and gypsum-based products, HPMC improves the workability and extends the open time, providing more convenience during construction applications.

HPMC in Construction Materials: In the construction industry, HPMC is widely used in various materials, such as mortars, tile adhesives, renders, gypsum-based products, and cement-based plasters. Here are some reasons why HPMC is used in construction materials:

1. Enhanced Workability: HPMC improves the consistency, flow, and spreadability of construction mixtures, making them easier to handle and apply.

2. Water Retention: HPMC's water retention properties allow for better hydration of cement and gypsum, reducing cracking, shrinkage, and improving overall durability.

3. Adhesion and Cohesion: HPMC acts as a binding agent, improving the adhesion between the construction material and the substrate, as well as enhancing the cohesion within the material itself.

4. Anti-Sagging and Anti-Slipping: HPMC's thickening properties help prevent sagging or sliding of vertically applied materials, such as tile adhesives or renders.
    

In the construction ,There are different usage. hpmc for tile adhesive ,Wall Putty , tile grout , plaster , gypsum , dry mortar , crack filler , tile glue , self-sevelling On the mortar , tile adhesive . generally there are some problems as below . Hollow drum Delamination Explode dust Crack

HPMC in the wall putty

1) Wall Putty powder dries quickly When it is mixed, the putty powder dries quickly, and it is difficult for workers to construct The putty powder loses water quickly after scraping by workers, and the putty powder cannot be properly compressed or dries too fast after construction.
2) The putty layer is scraped and rolled, and the skin is rolled in batches The base surface is too dry The temperature at the construction site is too high.
3) The wall putty has many bubble The air is too humid
4) The wall putty Powder drop and delamination After it is completed ,it is dry . The powder will fall off when touched by hand, and in serious cases, there will be peeling between the front and rear putty or between the putty and the substrate. The wall putty is applied at high temperature and ,the moisture evaporates quickly . There is not enough moisture to solidify, so it is easy to depowder
5). Cracking Cracks in the putty layer Single batch scraping is too thick, The important thing is to dry too fast, The drying speed of the surface layer and the inner layer is different, of course, there are many kinds of cracks.
