Zinc oxide has different functions in different industrial fields. For example, it has a coloring effect in styrene-butadiene rubber. Used in laminated glass to improve clarity and chroma. Application in rubber can improve high temperature aging resistance. Besides, zinc oxide brings convenience to our daily life. Adding zinc oxide to the sole increases the strength of the sole. It also has more features, which is a huge convenience for everyone. But what should I do if there are impurities in zinc oxide when it is used? At this time, we must do everything possible to remove it.
Our products also have a Foaming Agent, which is generally used to block the gaps of doors and windows, and connect the gaps of doors and windows through its filling function to achieve a sealing effect; the color Masterbatch Foaming Agent is the matrix of the color masterbatch. The special color masterbatch generally uses the same resin as the product resin as the carrier, and the two have the best compatibility; there is also a Powdered Foaming Agent, principle and application. Adding some fillers to plastics can improve certain properties of plastics. , more suitable for some special purposes; there are also Plastic Foaming Agent, which are used to disperse liquids on the surface of solid particles to form stable foams. We have a large inventory, if you want to know more, please contact us, we will be happy to help you!
1. The first step to remove iron impurities is to filter while hot, otherwise zinc sulfate will crystallize out into the sludge, reducing the output rate.
2. Use a high-temperature oven to dry out the internal structure. The fundamental reason is to remove the carboxyl group in the organic compound.
3. Be sure to make zinc oxide react with sulfuric acid to form zinc sulfate, so as not to introduce a new impurity, and at the same time, it can more completely remove the crystal water in the compound.
By adopting the above method, the impurities in zinc oxide can be completely cleaned, and the quality of zinc oxide can be improved, making it stronger to meet the requirements of industrial production, completing resource recycling, and increasing economic benefits, thereby reducing the impact on nature. damage of environment.
