Different types of desiccants have different compositions, and not all desiccants will explode when they encounter water. Sun Chuanqing told reporters that the natural mineral desiccant in Xianbei is actually a montmorillonite desiccant and is a mineral silicate. When it comes in contact with water, water molecules enter the structural space within the solid layer and have strong water absorption. . Montmorillonite desiccant has no obvious reaction with water, and there is no danger of explosion.
According to Sun Chuanqing, the lime desiccant is a lime desiccant whose main component is calcium oxide. When calcium oxide meets water, it will produce a sharp chemical reaction and instantly release a lot of heat. If the amount of lime contained in the plastic bottle is relatively large, the heat generated by the chemical reaction will cause the plastic bottle to rapidly expand. In severe cases, the plastic bottle will burst. Lime desiccant does not explode when it encounters water. It must satisfy two conditions at the same time: one is the confined space, and the second is that the amount of lime is sufficient, the reaction releases enough heat, the temperature reaches a certain value, and the water vapor expands rapidly, making the confined space The pressure increases. The experiment conducted by the reporter did not involve an explosion. It was related to the low amount of lime added and the material of the mineral water bottle.
The reporters found out that the chemical department of Weifang University had experimented with using 6 packages of 90 grams of quicklime desiccant to pour into a bottle containing about 120 milliliters of water, which eventually caused the bottle to explode.
Machining Stainless steel is the use of CNC machining out, including drilling, boring, cutting, turning, screw, etc.. Machining stainless steel commonly used materials: sus303304316.stainless steel has a very high hardness after machining, easy deformation, so in the process of rough machining to eliminate stress, and then finished. Surface treatment is generally passivation, we have specialized laboratories to test products, and ensure that each size to meet the requirements of the drawings, including the machining stainless steel application in various industries: automobile, ship, crane, medical equipment, industrial automation equipment.
Of course,we also accept the custom machining,welcome to contact us.
