Why do nitrile products factories use defoaming agents?
1、 Foam problems in the production of nitrile products Stirring and mixing process: During the production process, nitrile rubber needs to be mixed with other ingredients (such as vulcanizers, fillers, plasticizers, etc.). During this process, due to the stirring and mixing operations, air is introduced and foam is formed. Pouring and molding process: During the pouring and molding process of nitrile rubber products, if the foam is not eliminated in time, holes or bubbles will be left in the product, affecting the density and strength of the product. Effect of surfactants: Some chemical additives used in the production process may contain surfactants, which can reduce the surface tension of liquids, leading to the formation of foam. Temperature and pressure changes: In high-temperature and high-pressure environments, air or other gases in nitrile rubber may expand and form foam.
2、 The purpose of using defoaming agents is to improve product quality: Defoaming agents can reduce or eliminate foam generated during the production process and avoid bubbles or holes in the product, thereby improving product quality and consistency. Improved production efficiency: Reducing foam can speed up the production process, reduce downtime and cleanup caused by foam, and improve overall production efficiency. Optimize process conditions: Defoaming agents help maintain the stability and reliability of the production process and avoid fluctuations in process parameters caused by foam problems. Reduce costs: By reducing foam, you can reduce the waste of raw materials and reduce production costs.
3、 Methods of using defoaming agent 1. Direct addition: Add defoaming agent directly during the mixing or stirring process. 2. Pre-mixing: Pre-mix the defoaming agent with certain components before adding it to the nitrile rubber. 3. Spray addition: Defoamer is added by spraying in specific process steps.
