Hydroxypropyl methyl cellulose for wall spraying!

Hydroxypropylmethylcellulose products specifically designed for construction are widely used to improve the performance of hydraulic building materials, such as cement and gypsum. In cement-based mortar, it can improve water retention, extend correction time and opening time, and reduce sagging.

a. Water retention

Building specific hydroxypropyl methyl cellulose prevents water from seeping into walls. An appropriate amount of water remains in the mortar, allowing the cement to hydrate for a longer time. The water retention is directly proportional to the viscosity of the cellulose ether solution in the mortar. The higher the viscosity, the better the water retention. Once water molecules increase, their water retention decreases. Because for the same amount of building specific hydroxypropyl methyl cellulose solution, an increase in water content means a decrease in viscosity. The improvement of water retention can lead to an extension of the curing time of the mortar being constructed.

b. Improving construction performance

The application of hydroxypropyl methylcellulose HPMC can improve the workability of mortar.

c. Lubrication capacity

All air entraining agents have the function of wetting agents because they reduce surface tension and help disperse fine powder in mortar when mixed with water.

d. Anti sagging

Good anti flow and sagging mortar means that there is no risk of sagging or downward flow during construction in thick layers. The resistance to sagging can be improved by building specific hydroxypropyl methyl cellulose. The construction specific hydroxypropyl methyl cellulose produced by Shandong Chuangyao Company can provide mortar with good resistance to sagging.

e. Bubble content

High bubble content leads to better mortar yield and workability, reducing the formation of cracks. It also reduces the strength value and exhibits a phenomenon of "liquefaction". The bubble content usually depends on the stirring time.

Advantages of hydroxypropyl methyl cellulose in building material construction:

Hydroxypropylmethylcellulose has unique properties in the application of building materials, from mixing to dispersion to construction, as follows:

Compounding and configuration:

1. Easy to mix with dry powder formula.

2. It has the characteristic of cold water dispersion.

3. Effectively suspend solid particles, making the mixture smoother and more uniform.

Dispersion and mixing:

1. A dry mix formula containing hydroxypropyl methylcellulose can be easily mixed with water.

2. Quickly obtain the required consistency.

3. Cellulose ether dissolves faster and has no clumps.

Online construction:

1. Improving lubricity and plasticity to enhance processability makes product construction more convenient and efficient.

2. Enhance water retention characteristics and extend working time.

3. Helps to prevent sagging of mortar, mortar, and tiles. Prolonged cooling time and improved work efficiency.

Finished product performance and appearance:

1. Improve the bonding strength of ceramic tile adhesives.

2. Enhance the anti cracking shrinkage and anti cracking strength of mortar and board joint fillers.

3. Improve the air content in the mortar, greatly reducing the possibility of cracks.

4. Improve the appearance of the finished product.

5. It can enhance the anti sagging performance of ceramic tile adhesives.

Chuangyao hydroxypropyl methyl cellulose (HPMC) is a non-ionic cellulose ether prepared from pure cotton through a series of chemical processes. Hydroxypropylmethylcellulose (HPMC) is a odorless, odorless, and non-toxic white powder that can dissolve in cold water to form a transparent viscous solution. It has properties such as thickening, adhesion, dispersion, emulsification, film formation, suspension, adsorption, gelation, surface activity, water retention, and protective colloid.

Chuangyao hydroxypropyl methyl cellulose is produced and sold by our factory as a whole, using pure cotton as the raw material, with favorable prices, good product stability, and high cost-effectiveness. At present, it has been sold throughout the country and has been recognized by a large number of users.
