Plastic pipe as an important part of chemical building materials, with its superior performance rigid pvc plastic sheeting, hygiene, environmental protection, low power consumption and other widely accepted by the majority of users, mainly UPVC drainage pipe, UPVC pipe, aluminum-plastic composite pipe pvc plastic board supply, polyethylene (PE) water pipe these types. Plastic pipe is made of high-tech composite construction chemicals, building materials and chemical after following the steel, timber, cement, contemporary new fourth category of new building materials. Chemical building materials in our country has made considerable progress in the rapid development, especially the widespread use of new environmentally friendly plastic pipe, setting off a sound alternative to traditional building materials revolution. Plastic pipe has a water loss due to a small, energy, materials, ecological protection, convenience and other advantages completion pvc plastic board manufacturers, widely used in building water supply and drainage, urban drainage and gas pipes and other fields, has become the new century, the main force of urban construction pipeline . PVC for most inorganic acids and bases are stable, heat is not dissolved but is divided interpreted hydrogen chloride. Azeotroped with potassium hydroxide to obtain a brown insoluble unsaturated products. PVC solubility and molecular size and polymerization methods. Generally the solubility of the polymer with increasing molecular weight decreases, the solubility of the resin emulsion method than the difference in the resin suspension. It can be dissolved in ketones (such as methyl hexyl ketone, cyclohexanone), aromatic solvents (e.g. toluene, xylene), dimethylformamide, tetrahydrofuran. Polyvinyl chloride resin at room temperature is almost insoluble plasticizer, significant swelling at high temperatures, even to dissolve. PVC material is not easily flammable, high strength, resistance to climate variability and excellent geometric stability. PVC oxidant, reductant and acid has a very strong resistance. However, it can be concentrated oxidizing acids such as sulfuric acid, concentrated nitric acid corrosion and does not apply to contact with aromatic hydrocarbons, chlorinated hydrocarbons occasions.
