Polyurethane products are a series of products produced by people on the market with polyurethane as the basic raw material. It is mainly used in large-scale heavy industrial production enterprises such as mines, coal washing plants, power plants, and iron and steel plants. The polyurethane products produced mainly include polyurethane screens and plates, and polyurethane cyclones. Compared with other rubber and nylon products, it has the characteristics of abrasion resistance, hydrolysis resistance and high temperature resistance.
Composition and characteristics of polyurethane products The high-strength and rigid polyurethane foam cold insulation pipe bracket is made of multifunctional organic isocyanate and mixed polyether polyol as the main raw materials. In the presence of catalysts and various special additives, they interact and undergo complex chemical reactions. Rigid polyurethane foam prepared by reaction? In the production process of the product, due to the selection of specific polyurethane raw materials with greater functionality, and the scientific selection of screening aid materials and material ratios, the compressive strength and physical and chemical properties of the product are effectively improved. The cold-insulation pipe bracket products produced can fully meet the requirements of the application process.
Tested by relevant authoritative departments, all indicators have reached or exceeded the technical level of similar foreign products. Polyurethane products have the following advantages: High density, according to different applications, the density can be adjusted between 200~500kg/cubic. The compressive strength is high, up to 4-20MPa. The thermal conductivity is 0.052. Low thermal conductivity, low moisture permeability, low water absorption, meeting the requirements of cold storage. Does it have excellent chemical properties such as water-resistant solution stability, anti-aging, acid and alkali resistance? It is not easy to burn, and its flame retardancy meets the national safety requirements for density; -The density of the -165°-180° pipe seat is between 300-500. Insulation thickness 100mm
General advantages and characteristics of polyurethane products:
1. Good wear resistance: polyurethane products have excellent wear resistance
2. Wide range of hardness: The hardness of polyurethane products is about Shore A10-D80, while the hardness of ordinary rubber is generally Shore A60-100. It is worth noting that the polyurethane elastomer can have an elongation of 400-800% within such a hardness range. The maximum hardness of natural rubber at an elongation of 550 is Shore A70.
3. Polyurethane products have high strength and high elongation.
4. Excellent oil resistance: The oil resistance of polyurethane products is better than that of cyanide rubber; the aging resistance is better than natural rubber and other synthetic rubbers; in terms of resistance to hydrolysis and corrosion by acid and alkali solutions, polyether PUR is better than polyester PUR.
5. Polyurethane products have excellent characteristics such as light weight, high strength, heat insulation, sound insulation, flame retardant, cold resistance, corrosion resistance, no water absorption, simple and quick construction, etc., and have become thermal insulation materials in industrial sectors such as construction, transportation, petroleum, and chemical industries. , Electricity, refrigeration, etc., waterproof plugging, sealing and other indispensable materials.
