In the middle and late 1990s, after some domestic enterprises introduced advanced rotomolding equipment and technology from abroad, they began a large-scale industrial production in the true sense. At present, domestic enterprises have been able to prepare large-scale plastic products such as chemical storage tanks with a container volume of over 20,000 L and high-speed plastic yachts. In recent years, China's rotomolding industry has developed rapidly. There are nearly 100 rotomolding manufacturers in various parts of the country. These manufacturers produce more and more rotomolded PE storage tank products, and the application fields are more and more extensive. However, compared with the advanced level of foreign developed countries, the gap is still very obvious.
In the early 1990s, more than 5,000 rotomolding products were registered in the Rotomolding Association of the United States, and there are only more than 40 kinds in China. The rotomolding products of foreign countries have involved more than 30 industries, and China's rotomolding PE storage. Can products only involve more than ten industries. In terms of rotomolding raw materials, at present, in the domestic rotomolding products, the rotomolding of polyethylene and its composite materials on the market accounts for about 75% of the total rotomolding products, and more than 99% of the rotomolding products are PE, of which 95% is also a rotomolding grade LLDPE that is very suitable for rotational molding, while the proportion of foreign rotomolded polyethylene materials is roughly: 65% for LLDPE, 2% for XHDPE (crosslinked polyethylene), 10% for HDPE, LDPE It is 5%.
In order to adapt to the increasing variety of rotomolded PE storage tanks, the scientific and technological content of rotomolded products has been continuously improved, and the demand for rotomolded products in various industries has been increasing. This is largely due to the establishment of the China Plastics Processing Industry Association. Plastic professional committee. The company aims to exchange the production technology and experience of rotomolding process, digest and absorb foreign advanced technology and equipment, strengthen technical cooperation, promote the development of rotomolding process technology, processing equipment and molds in China, and develop rotomolding special materials and products.
