In earlier years, polypropylene fiber lifting belt belongs to one of the most professional lifting belt in China, with extremely high acid and alkali, but with the development of science and technology, the emergence of the polyester fiber lifting belt pull polypropylene lifting belt down from the altar, is famous for its high strength and high load, became widely popular lifting products at present, and has instead of the metal hook.
So the polypropylene lifting belt really fell apart? It is not true that polypropylene lifting belt with a very high acid and alkaline resistance, still has a bright performance in their own work field, which is incomparable to polyester lifting belt. Especially in the face of alkaline environment lifting operations.
Although polypropylene production technology level is relatively backward, the industry generally believes that the strength of polyester is greater than polypropylene. In fact, polypropylene in the use of advanced equipment, technology, determined by its structural properties, after many times of drafting, get very close molecular structure, strength is better than polyester. Dacron has good acid resistance, but poor alkaline resistance. Weak alkali can decompose it, so it is not suitable for use in any possible alkaline environment.
It can be seen that polyester lifting belt is excellent, but it is not all-powerful, and polypropylene lifting belt although has come down the altar, but in some special environment lifting operations, it is still an irreplaceable member.
