PVC hose reinforced plastic, plastic hoses, PVC hoses, simple plastic materials related knowledge introduction
Applications: plastic hose is usually used as suction and delivery pipe is particularly suitable for solids such as dust and fiber suction, gaseous and liquid media, industrial dust and suction equipment, air conditioning and ventilation systems dedicated hose, as an anti-wear protection tube.
Properties: Internal smooth, good alkali metals and acidity can, good chemical resistance, good UV and ozone resistance, bending radius is small, gas and liquid does not leak;
Structure: hard plastic spiral wall cladding, pipe wall smooth;
Ingredients: wall: soft PVC, spiral wire: Hard PVC;
Temperature range: about -5 掳 C to 80 掳 C;
Color: gray (standard), customers can special order other colors;
    PVC hose reinforced plastic, plastic hoses, PVC hoses
Simple plastic-related knowledge introduction:
Advantages of plastic
1, most of the plastic of the corrosion resistance, strong acids, alkali reaction does not.
2, low-cost plastic.
3, durable, waterproof, lightweight.
4, easy to be molded into different shapes.
5, is a good insulator.
6, the plastic can be used in the preparation of fuel oil and fuel gas, which can reduce oil consumption.
Plastics and other materials compare <1> resistance to chemical attack, it is widely used in building materials industry. <2> shiny, partially transparent or translucent <3> mostly good insulator <4> light weight and strong <5> process easy mass production, cheap <6> versatile, multi-utility, easy coloring, part of the high temperature
Material Description:
PVC is actually a vinyl polymeric material, the material is a non-crystalline materials. PVC material in actual use, often by adding stabilizers, lubricants, auxiliary processing agents, pigments, impact agents and other additives. 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.
Polypropylene (PP plastic) is another fine nylon resin varieties Following the development, it is a high-density, non-linear polymer side chain, high crystallinity will, with excellent overall performance. When uncolored white translucent, waxy; lighter than polyethylene. Transparency is also better than the polyethylene, rigid than polyethylene.
PE plastic namely polyethylene plastic, corrosion resistance, electrical insulation (especially high-frequency insulation), the mortgage is suitable for the production of polyethylene corrosion-resistant parts and insulating parts; suitable for production of high-pressure polyethylene films; UHMWPE suitable for production of shock absorption, abrasion resistance and transmission parts.
ABS resin (acrylonitrile - styrene - butadiene copolymers, ABS Acrylonitrile Butadiene Styrene is the first letter of the acronym) is a high strength, good toughness, easy molding of thermoplastic polymer materials. Because of its high strength, corrosion resistance, high temperature, so often used in the manufacture of plastic instruments.
PE plastic namely polyethylene plastic, corrosion resistance, electrical insulation (especially high-frequency insulation), the mortgage is suitable for the production of polyethylene corrosion-resistant parts and insulating parts; suitable for production of high-pressure polyethylene films; UHMWPE suitable for production of shock absorption, abrasion resistance and transmission parts.
PS plastic (polystyrene) English name: Polystyrene weight: 1.05 grams / cubic centimeter molding shrinkage: 0.6-0.8% molding temperature: 170-250 鈩 drying conditions, material properties: electrical insulation (especially high-frequency insulation) fine, colorless, transparent, light transmittance after the plexiglass, colored water resistance, good chemical stability, strength in general, but the crisp, easy to produce brittle fracture stress, impatience benzene gasoline and other organic solvents. suitable for production insulating transparent pieces, decorative pieces and chemical equipment, optical instruments and other parts.
Forming properties: 1. amorphous material, moisture absorption is small, does not have to fully dry, not easily broken, but the thermal expansion coefficient, easy to produce stress, good liquidity, available screw or plunger-type injection molding machine. 2. suitably high melt temperature, high mold temperature, low injection pressure, injection time extend help to reduce stress, prevent shrinkage. Deformation. 3. Available in various forms gates, gate and plastic parts arc connection, in order to avoid place plastic parts damaged gate. Drafts of large, top out evenly. plastic uniform thickness, preferably without the inserts, if any inserts should be preheated.
