APPLICATION METHOD AND FUNCTION OF HYDROXYPROPYL METHYL CELLULOSE IN BUILDING MATERIALS

Application method and function of hydroxypropyl methyl cellulose in building materials
The application method and function of hydroxypropyl methyl cellulose HPMC in various building materials.

1. Use in putty
In the putty powder, HPMC plays the three major roles of thickening, water retention and construction.
Thickener: Cellulose thickener plays a suspending role to keep the solution uniform and up and down to prevent sagging.
Construction: HPMC has a lubricating effect and can make the putty powder have good construction performance.
2. Application of cement mortar
The mortar without water-retaining thickener has higher compressive strength, but its water-retaining performance, cohesive performance, softness is poor, bleeding is large, and the operating feel is poor, so it cannot be used basically. Therefore, the water-retaining thickening material is expected An indispensable ingredient for mixing mortar. Under normal circumstances, adding hydroxypropyl methylcellulose or methyl cellulose to the mortar, the water retention rate can reach more than 85%. The method used in the mortar is to mix the dry powder and add water. Cement with high water retention properties can be filled with water, the bonding strength is significantly improved, and the tensile and shear strength can be appropriately increased, which greatly improves the work efficiency.
3, the application of ceramic tile bonding
Hydroxypropyl methylcellulose tile adhesive can save tile pre-foaming water;
The specifications are pasted and firmly;
The posting technical requirements for employees are relatively low;
There is no need to fix with cross plastic clips at all, the paste will not fall off, and the bonding is firm;
There is no excess mud in the cracks of the bricks, which can avoid the surface pollution of the bricks;
Several tiles can be pasted together, not like a single piece of cement mortar.
4, the application of caulking and caulking agent
Adding cellulose ether can make the edge bonding performance good, the shrinkage rate is low, and the wear resistance is strong, so as to protect the base material from mechanical damage, and avoid the adverse effect of water infiltration on the overall structure.

HYDROXYPROPYL METHYL CELLULOSE HPMC IN BUILDING MATERIALS

Hydroxypropyl methylcellulose(HPMC) is a nonionic cellulose ether prepared by a series of chemical processing using natural polymer material cellulose as a raw material. They are an odorless, odorless, non-toxic white powder that swells in cold water into a clear or slightly turbid colloidal solution. It has the characteristics of thickening, bonding, dispersing, emulsifying, film forming, suspension, adsorption, gelation, surface activity, moisture retention and protective colloid. Hydroxypropyl methylcellulose, methyl cellulose can be used in construction materials, coatings industry, synthetic resin, ceramic industry, medicine, food, textile, agriculture, daily chemical and other industries.
Hydroxypropyl methylcellulose (HPMC) Chemical equation:
[C6H7O2(OH)3-m-n(OCH3)m(OCH2CH(OH)CH3)n]x

The main application of hydroxypropyl methylcellulose HPMC in building materials:
1. Cement based plaster

10. Ready-mixed mortar
HPMC products for ready-mixed mortar are better than ordinary products in the ready-mixed mortar, ensuring that the inorganic cementing material is fully hydrated, significantly preventing the bond strength from being caused by excessive drying, and Crack caused by drying shrinkage. HPMC also has a certain venting effect. The HPMC product for premixed mortar has a proper amount of venting, uniformity and small bubbles, which can improve the strength and smearing of the ready-mixed mortar. The HPMC product specially used for ready-mixed mortar has a certain retarding effect, which can extend the opening time of the ready-mixed mortar and reduce the construction difficulty.

Main Characteristic Of Hydroxyethyl Methylcellulose

What is hydroxyethyl methylcellulose (HEMC)?

Hydroxyethyl methyl cellulose (HEMC) is also named as methyl hydroxyethyl cellulose (MHEC). It is a white, grayish-white, or yellowish-white granules.

It is a non-ionic cellulose ether derived from the addition of ethylene oxide to methylcellulose. It is produced from a natural renewable polymer such as wood pulp or cotton.HEMC can be used as a highly efficient water retention agent, adhesives and film-forming agent, stabilizer, etc.It is widely used in different industrial applications such as oil drilling, construction, and building, paint and coating, pharmaceutical, etc.HEMC can be modified according to customers’ requirement and still have its good anti-sagging property and good workability after modification.
