Dispersible latex powder product identification method

December 3, 2021by admin0

Customers of redispersible latex powder do not know how to distinguish the quality of redispersible latex powder. Below, our company will share the three distinguishing methods with you. I hope to help you:
1. Dissolution: Take a certain amount of rubber powder and dissolve it in 5 times the mass of water, stir it and let it stand for 5 minutes and observe it. In principle, the less insoluble matter precipitated to the bottom layer, the better the quality of the rubber powder.
2. Film formation: take a certain amount of rubber powder, dissolve it in 2 times the water, stir it and let it stand for 2 minutes, stir again, and pour the solution on a flat clean glass, the glass is ventilated and shaded. After being fully dried, take it off and observe the polymer film that has been taken off. The transparency is high and the quality is good. Then pull moderately, good elasticity and good quality. Then cut the film into strips, soak in water, and observe after 1 day, the quality of the less dissolved in water is good.
3. Ash content: Take a certain amount of rubber powder, weigh it, place it in a metal container, heat it up to about 500 degrees, cool it to room temperature after 500 degrees of high temperature burn, and weigh it again. The light weight is good.
