    Zhengmeihao introduced Canada's new high-strength wear-resistant and corrosion-resistant material-polyurethane elastomer. It can withstand the corrosion of acid, alkali, oil, water and other media with a PH value of 3-11, excellent corrosion resistance, high resistance to salt spray corrosion, and good freeze resistance; and it has high toughness, easy construction, hardening, and high strength. , Good plasticity, resistance to bending fatigue and contact fatigue, high dynamic load performance, non-adhesion, high strength, wear resistance, corrosion resistance, self-lubrication, etc. At the same time, spray-type polyurethane elastomers are not easy to age, low friction, and a wide range of hardness ( From Shaw A30 to Shaw D90 can maintain high elasticity).
    Spray type polyurethane spray equipment elastomer is a mature process technology, which can be widely used in sewage treatment, mining, port, power, coal and other complex conditions to enhance the wear resistance and corrosion resistance of new types of polymer polymers. Damage to anti-corrosive materials. Spray-type polyurethane has excellent wear resistance, corrosion resistance, impact resistance, salt spray corrosion resistance, aging resistance, flexible elasticity, strong adhesion and other properties; in the immersed state, the wear resistance is 8 times that of hard alloy steel, which is 7 times of vulcanized rubber, 3 times of ultra-high molecular polyethylene; and has strong adhesion properties. Different primers and adhesives can be configured according to different substrates. It can be used for all metal and non-metal substrates. Find matching primers and adhesives; construction is also very convenient: just normal temperature, not sensitive to moisture and temperature; no pollution to the environment, no volatile organic compounds (VOCs), a new type of environmental protection Material; fast curing at room temperature, no catalyst; beautiful color, good reproducibility of the prototype, continuous and dense coating, no joints, no pinholes, excellent UV resistance.
    Solvent type polyurethane spray products
    The product system can be regarded as a whole composed of two components, component A is a synthetic resin or equivalent, and component B is a curing agent.
    For those who want to use spray polyurethane but are not willing to invest heavily in using 100% solid polyurethane, the Normank solvent-based polyurethane spray product line is an ideal choice. This product can be used on low cost (US $ 200-US $ 300) gravity spray gun or airless electric spray gun.
    The advantage of this solvent-based product is that it can be sprayed on product parts that are relatively small and difficult to cover the entire surface with large sprays, such as vibrating feeders, small-caliber pipes, elbows, pumps, and impellers.
    100% solid based polyurethane spray products
    The two-component 100% solid-based, shrink-resistant polyurethane repair material exists in the form of cement and is packaged in a can or other convenient field-use packaging method. For products with elastic properties such as rubber, polyurethane linings, conveyor belts, pulley insulation, etc., the repair of damaged parts has achieved remarkable results. Polyurethane repair material belongs to room temperature curing, solvent-free polyether adhesive type; it has the characteristics of fast curing speed, simple operation, easy use, good filling, non-toxic and tasteless, medium resistance, aging resistance, high bonding strength, high insulation strength, etc. ; After curing, it has high toughness, wear resistance, corrosion resistance, impact resistance and cavitation resistance.
    Polyurethane repair material
    Polyurethane repair materials can be painted into coatings of any thickness after mixing and mixing. Because the materials do not have volatile components, the coatings will not shrink. The cured surface can be machined or polished to a smoother surface. These characteristics make it easier to obtain a consistent and smooth repair effect on the surface of the original substrate when surface repairing is carried out with a polyurethane repair material.
    Polyurethane repair materials can be used to solve the repair problems of many elastomers. They can be used for the repair of rubber products, steel cores and ordinary conveyor belts. , Repair of edge wear, surface perforation and joint sealing; bonding, insulation sealing and repair of cables, rubber linings, tires, rubber impellers, rubber rollers and other rubber products; it can also be used for cavitation resistance and anti-cavitation Preparation of impact-resistant and wear-resistant rubber lining coating.
