In mortar, redispersible polymer powder can improve the engineering construction characteristics of rubber powder, improve the fluidity of rubber powder, improve thixotropy and sag resistance, improve the cohesive force of rubber powder, improve water-solubility, and increase the time when it is opened to the outside world. between. After the cement mortar is dried and solidified, it can increase the compressive strength, increase the tensile strength, reduce the elastic mold, and improve the specificity. redispersible polymer powder has good film-forming adhesion, and its application can be seen in construction and decoration projects.
The resin rubber powder latex film has a self-pulling structure, which can release the supporting force to the joint with the cement mortar anchor. According to this internal strength, the cement mortar is maintained in general and the cohesion of the cement mortar team is improved. The existence of high elastic polymer improves the ductility and ductility of cement mortar. The principle of increasing yield stress and ineffective compressive strength is as follows: When the force is released, the micro-cracks will delay the time until the in-situ stress expands due to the increase in ductility and ductility. In addition to this, the interlaced polymer regions also have a blocking effect on the micro-cracks combined by the cracks. Therefore, the dispersed natural latex powder can increase the ineffective stress and ineffective strain of the raw material. The polymer film in the polymer modified material cement mortar is a key hazard to the hardened cement mortar. Dispersion of dispersible polymer powders plays another leading role at the page, which is to improve the adhesion of the raw materials in contact.
The vast majority of dispersible polymer powders that people generally see in construction are milky white, although some other shades may appear. The composition of redispersible latex powder is mainly composed of high polymer epoxy resin preservative (internal and external) maintenance colloid solution and resistance agent. Among them, the high polymer epoxy resin is located in the key position of the rubber powder particles and is the key component of the dispersible polymer powder.
The dispersible polymer powder does not need tap water in storage and transportation, which can save the transportation cost of engineering building modules and make transportation convenient and fast. The redispersible natural latex powder manufactured by the cement mortar factory has a long shelf life and can be stored for a long time without worrying about ultra-low temperature freezing and convenient storage. Each bag of dispersible polymer powder is relatively small in volume, light in weight, and easy to use.
