Redispersible latex powder is the main additive of the new material cement dry powder mortar. It has been widely used in exterior wall insulation, coatings, floor mortars, polymer cement-based waterproof coatings and various building materials. As redispersible latex powder is a process in which emulsion is dried to produce latex powder,

The water retention of dry mortar refers to the ability of the mortar to retain and lock moisture. The higher the viscosity of hydroxypropyl methyl cellulose ether, the better the water retention. Since the cellulose structure contains hydroxyl and ether bonds, the oxygen atoms on the hydroxyl and ether bond groups associate with water molecules to form hydrogen bonds, so that free water becomes bound water,

Hydroxypropyl methyl cellulose HPMC is used as a dispersant, thickener and binder in construction treatment, and is mainly used in the molding of cement mortar and gypsum products. It is used in cement mortar to increase its adhesion, reduce flocculation, improve viscosity and shrinkage, and have water retention. Reduce the moisture loss and strength of the concrete surface, prevent cracks and weathering of water-soluble salts;

The special latex powder for tile adhesive is a new type of tile adhesive made by using cement as a gelling agent, adding high molecular polymers and inorganic powders as water-retaining agents and adhesives. It can also be applied to thin tiles. Layer bonding.

Redispersible latex powder is a powder binder made from a special polymer emulsion spray-dried. This powder can be quickly redispersed to form an emulsion after contact with water, and has the same properties as the initial emulsion. Therefore, the emulsion used for the production of redispersible latex powder should also have the following special properties compared with ordinary emulsions directly used for adhesives:

Putty powder is mainly divided into gypsum-based putty powder, lime-calcium-based putty powder and cement-based putty powder according to the main raw materials. What is the difference between these three types of putty powder? How do we choose the appropriate type of putty powder in practical applications?

Cellulose ether is mainly used to retain water and increase smoothness. It can solve the doubts about drum cracking and initial strength during the construction process. Cellulose ether mainly plays the role of water retention, adhesion and smoothing.

Application of redispersible latex powder
1. Self-leveling floor paint in cement mortar: the matching property, bending strength and cohesiveness of the elastic mold of cement mortar. Improve the wear resistance and adhesive compressive strength and cohesion of cement mortar.

When you produce and use putty, there will be various problems. Today we are talking to you that after you mix the putty powder with water, when you stir it with an electric drill, the putty will become thinner and the water will separate. Seriously, the root cause of this problem is the hydroxypropyl methyl cellulose added in the putty powder. Let us understand the principle of action together.
