Take sufficient amount of redispersible latex powder and melt it in 5 times of water, mix it well and leave it for 5 minutes and then close the inspection. In principle, the smaller the inadmissible material settled to the bottom layer, the higher the quality of the redispersible latex powder. This is a simple and easy way.
The operation method of dispersible emulsion powder is film forming method:
Take a certain quality of redispersible latex powder, melt it in 2 times of water, mix it well and leave it for 2 minutes, mix it well again, pour the solution on a piece of clean glass, which is placed in the back shade of air circulation. Allow to dry sufficiently and then remove. Check the removed polymer film. Good quality with high transparency. The film is then pulled appropriately and the elasticity is good. The film is cut into strips, soaked in water, and then inspected after 1 day, and the one with less water melting is of good quality. This type of way is more factual.
Redispersible emulsion powder can increase the dense fusion of cement mortar particles and polymer film with each other. The adhesion is enhanced by filling with redispersible emulsion powder. Relatively enhance the ability of mortar to accept tangential stress, prompting the wear rate to be reduced, the wear resistance to be enhanced, and the service life of mortar to be extended by Ting.
Redispersible emulsion powder enhances freeze-thaw stability Reasonable prevention of material cracking, the plasticity of its thermoplastic resin, redispersible emulsion powder. It can overcome the damage of thermal expansion and contraction brought by temperature change on cement mortar material. It can overcome the shortcomings of dry shrinkage deformation and easy cracking of cement mortar, and make the material flexible, thus enhancing the durability and stability of the material.
