Calcium hydroxide metamorphism

Introduction: calcium hydroxide may deteriorate after long-term storage What about the deterioration of calcium hydroxide? Let the small editor of Baibai safety net lead you to learn more about it! With the continuous progress and development of society, China's demand for the use of calcium hydroxide is not short to expand More and more factories and enterprises select calcium hydroxide with good quality through restructuring However, when using calcium hydroxide without attention, it will cause calcium hydroxide metamorphosis How about calcium hydroxide? Baibai safety net and you to understand it! The results show that: 1 The thermal decomposition or thermal crosslinking of Jiangxi calcium hydroxide can be caused by temperature marching temperature But the fundamental role of heat is still activation It is a common aging phenomenon that the rate of oxygen relaxation and activation oxidation reaction, and then the rate of calcium hydroxide oxidation reaction is accelerated 2 The oxygen stored in the air for a long time reacts with the rubber molecules in Fujian calcium hydroxide, and the molecular chains crack or cross-linking excessively, which results in the change of rubber function Oxidation is one of the important reasons for rubber aging In addition, the chemical active oxygen of ozone and ozone in the air is much higher and more damaging It also cracks the molecular chain, but the effect of ozone on calcium hydroxide varies with the deformation of rubber When it is used as a rubber reinforcing agent for deformation, cracks with the direction of stress action straight appear, which is called "ozone cracking" The chemical reaction between carbon dioxide and calcium hydroxide in the air is also one of the important killers of calcium hydroxide metamorphosis 3 The shorter the light wave is, the greater the energy is It is the ultraviolet with high energy that damages the calcium hydroxide in Jiangsu Province In addition to the cracking and cross-linking of rubber molecular chain directly caused by ultraviolet, calcium hydroxide broke free radicals due to absorption of light energy, which initiated and accelerated the reaction process of oxidation chain The external light plays the role of heating Another characteristic of light action is that it mainly grows on the surface of oak For the specimen with high glue content, there will be Network Cracks on both sides, which is called "light outer layer crack" The above is the answer about the deterioration of calcium hydroxide provided by Baibai safety net I hope my article will let you have a clearer understanding of this problem!
