Corrugated Plastic Bin is widely used in machinery, automobiles, home appliances, light industry, electronics, and other industries. It is favored by people for its acid and alkali resistance, oil resistance, non-toxic and tasteless characteristics. So what are the requirements for using the turnover box at different temperatures?
1. In the environment of -40~40℃, a high-strength blow molding turnover box is adopted. At present, the high-strength turnover box that is formed by extrusion blow molding is generally blow-molded with HMWHDPE plastic, and its weight average molecular weight reaches about 350,000 to 400,000; Adaptability, can be used stably in the environment of -40~40℃ and is the first choice for high-strength use environment. Due to the high cost of plastic raw materials selected for this high-strength blow-molded tray, the processing technology is difficult, and the product service life is particularly long, which can reach 5 to 10 years. Although the price of a single purchase will be higher, the comprehensive use cost is indeed lower. When high-strength use is required, this high-strength turnover box can be selected.
2. Under the ambient temperature of plus or minus 40 ℃, the turnover box made of polypropylene cannot be used, because polypropylene cannot resist low temperature. In addition, the plastic turnover boxes used on the shelves in the cold storage are preferably double-sided. When the goods are not heavy, you can choose Tian or Sichuan.
3. In the low-temperature environment of minus 30 ℃, select the turnover box made of modified polypropylene or low-pressure high-density polyethylene material. Modified polypropylene is a high-temperature incomplete polymerization product of polyethylene and polypropylene. It has both the willfulness of polyethylene and the low-temperature resistance of polypropylene, stable physical properties, wear resistance, and drop resistance. Large-scale chemical enterprises, low-temperature cold storage, and other environments are generally recommended to use low-pressure high-density polyethylene material for production. The turnover box of this raw material can withstand low temperatures of minus 30 °C.
