Polyurethane products are a series of products which are produced with polyurethane as the basic raw material in the market. They are mainly used in large-scale heavy industry factories such as mines, coal washery, power plants and steel mills. The polyurethane products produced mainly include polyurethane sieve plates, sheets, polyurethane cyclones, etc. Compared with other rubber and nylon products, they are more wear-resistant, hydrolysis-resistant and high temperature-resistant. Characteristic.
The product composition and characteristics of high strength rigid polyurethane foam cold pipe support is a rigid polyurethane foam made of multifunctional organic isocyanates and mixed polyether polyols under the condition of catalyst and various special additives. The polyurethane foam is produced by complex chemical reaction. The crushing strength of the product was effectively improved by using ester raw materials and scientific selection of screening auxiliaries and their proportions. The physical and chemical properties of the refrigeration tube bracket products can fully meet the requirements of the application process. By testing by the relevant authorities, the indexes have reached or exceeded the technical level of the same kind of products abroad.
Its products have the following advantages:
High density, can be adjusted according to different applications, density 200-500 kg/cubic? High compression strength, up to 4-20 MPa? Thermal conductivity 0.052. Low thermal conductivity, low moisture permeability, low water absorption, meet the requirements of cooling? Good performance of chemical drugs such as hydrolysis stability, aging resistance, acid and alkali resistance? Not easy to burn, flame retardant to meet the requirements of national security density; 165-180 degree tube The bulk density ranges from 300 to 500. The thickness of insulation layer is 100 mm.
