Speaking Xi'an plastic bucket We are no strangers, no matter we are filled with oil or water, we have performed very well. In some families, they also buy plastic buckets to hold water, which is very convenient to use. In some liquid production plants, the use of plastic buckets is even more necessary, such as industrial detergent, chemical plants and other places. In fact, the plastic buckets we usually see are very useful, and seldom deform. So when what happens, the plastic bucket in Xi'an will deform? Now let's get to know it with Xiao Bian.
After long-term use, Plastic water storage tank It is easy to deform when contacting, holding or approaching high temperature objects. There are usually two reasons for plastic cylinder deformation: melting and creep.
Plastic barrel melting is a qualitative change that occurs when the temperature approaches or exceeds the melting point of plastic under the influence of high temperature. There are also many kinds of plastics. Plastic is a kind of material with resin as the main component, which can be molded into a certain shape at a certain temperature and pressure, and maintain a certain shape at room temperature. There are many kinds of plastics and many classification methods, which are generally divided into thermoplastics and thermosets. Thermoplastic refers to materials that can soften or even melt and flow within a certain temperature range, and can be solidified into certain shapes after cooling, such as PE, PP, PVC, PS, PA, PC, etc., accounting for more than 95% of the total amount of plastics. Thermosetting plastic refers to the chemical change of resin during heating, which changes from linear polymer structure to blocky polymer structure. After that, it will not melt when heated and will not dissolve in organic solvents, such as phenolic plastic, urea formaldehyde plastic, epoxy resin, unsaturated polyester, etc. Thermoplastics can be divided into two categories according to their properties: ordinary plastics and engineering plastics. The same kind of plastic can be divided into homopolymer and copolymer. According to the use and processing method, the same kind of plastic resin can be divided into injection molding grade, extrusion grade, film grade, pipe grade, medium blow molding (blow molding) grade, etc. In order to accurately and conveniently select the resin brand, it is also called wire and cable material bottle grade material, washing machine inner barrel and other special materials.
In the creep process of Xi'an plastic bucket, the stress generated in the solidification process is slowly released with aging. The short-term deformation is affected by temperature change. Molecular segments receive energy to produce creep. Long term deformation is affected by aging, chain breakage, energy and other factors.
Plastic buckets made of different materials have different molding and high temperature resistance, so some plastic buckets are suitable for use in low temperature environments, while others have no problems in high temperature environments
