[0002] Polyurethane was first developed by German scientists in the 1930s. They synthesized a new material by polycondensing liquid isocyanate and liquid polyether or glycol polyester. The fluid raw material of polyurethane is stored in a cylinder, which facilitates the storage and transportation of polyurethane raw materials. With the rapid development of my country's polyurethane industry in recent years, polyurethane raw materials have been widely used in home appliances, automobiles, and thermal insulation building materials industries. The transportation, storage, environmental protection, and usage costs of polyurethane raw materials have become topics of common concern in the industry.
