Applications of HPMC Joint Filler
December 27th 2024
In industrial applications, there are many points of attention in the storage and use of redispersible latex powder. Shijiazhuang latex powder wholesalers come to share with you the following information on this aspect:
The redispersible latex powder mortar forms a film on the cavities and the surface, and the polymer film will not disperse twice after encountering water, which prevents the invasion of water and improves the impermeability. Special redispersible latex powder with hydrophobic effect, better hydrophobic effect. There are currently many rubber powder manufacturers on the market. In addition to foreign brands, there are still many domestic manufacturers producing, and even foreign manufacturers are also building factories and putting into production in China.
The product should be stored in a cool and dry place. The recommended period of use is 12 months. Please use it as soon as possible in summer. If stored in high temperature and humidity conditions, it will increase the chance of agglomeration. After opening the bag, please use it at once as much as possible, otherwise the bag should be sealed to avoid absorbing moisture from the air. A layer of hydrophilic material is wrapped on the surface of the redispersible latex powder particles. Most of the protective colloids of the redispersible latex powder are polyvinyl alcohol. Redispersible latex powder can be divided into styrene-butadiene copolymer, tertiary carbonate ethylene copolymer, ethylene-acetic acid acetic acid copolymer, etc., and on this basis, adding vinyl laurate and silicone to improve performance. Different modification measures make the redispersible latex powder have different properties such as water resistance, alkali resistance, weather resistance and flexibility.
