Zibo Hanxiang Ultrafine Calcium Hydroxide has low wholesale price
When using ultra-fine calcium hydroxide, we found that this material will aging after long-term use. At this time, how do we deal with it? What methods can prevent the ultrafine calcium hydroxide from aging? 1. Increasing the temperature can cause thermal cracking or cross-linking of ultrafine calcium hydroxide, but the basic role of heat is still activation, increasing the rate of oxygen diffusion and activating the oxidation reaction, thereby accelerating the oxidation reaction rate of ultrafine calcium hydroxide. It is a common aging phenomenon-thermal oxygen aging. 2. Ozone's chemical active oxygen is much higher and more destructive. It also breaks the molecular chain, but the effect of ozone on this product varies with the deformation of the rubber. It is used as a rubber reinforcement for deformation. When acting with stress ...
