frp pipe synopsis:
Polyvinyl chloride (PVC) is a kind of non-toxic, non-odorous white powder. Its chemical stability high, with good plasticity. Besides the minority organic solvent outside, under normal temperature resistant to any concentration of hydrochloric acid, less than 90% of sulfuric acid, nitric acid and 50-60% of 20% the following caustic soda, also quite stable for salts, PVC thermal stability and resistance to light the gender is poorer, in 140 degrees Celsius above, you may start decomposing and produce hydrogen gas, cause PVC discoloration. PVC of excellent electrical insulation, generally not burn up in flames can burn and produce hydrogen gas, but leave from extinguish fire namely, is one kind of "self-extinguishing RTV silicone compound", "difficult to burn sex" material. Based on the above characteristics, PVC mainly for the production of profiles, profile and tubing fitting, plank, sheet, cable sheath, hard or soft tube, blood transfusion equipment and film, etc.
PVC characteristic and molding character
Proportion: 138 g/cubic centimeters, molding shrinkage: 0.6-1.5%, molding temperature: 160-190 °C.
Features: mechanical performance, excellent electrical performance, acidproof alkali very strong, chemistry stability is good, but softening point low. Suitable for making thin plate, electric wire and cable insulating layer, seals, etc.
Forming features:
1 amorphous materials, moisture absorption small, poor liquidity. In order to improve the liquidity bubble, plastic, and prevent the occurrence of being dry. Mould gating system appropriate coarse short, sprue section should be big, can not have blind Angle. Mould should cooling, chromium plated.
2 due to its corrosive and liquidity characteristics, had better use special equipment and tooling. All products must according to need to join different kinds and number of additives.
3 extremely easy decomposition, in 200 degrees temperature and steel, copper contact easier to decompose, decomposition escaping from corrosion. Irritant fumes. Molding temperature range.
4 adopts screw injection machine nozzle, aperture appropriate big, just blind Angle stagnation expected. Okay, if have with insert insert should be preheated.
PVC range of applications
1 building drainage use rigid PVC pipe and fittings
Building drainage use rigid PVC pipe, tube things a PVL resin as main raw materials, join specialty auxiliaries in the Canon pipe-maling machine, extrusion and injection molding and into.
characteristics
    (1) physical excellent performance. UPVC pipe, tube corrosion resistance, impact resistance and high strength, fluid resistance small, not fouling, inside sleek, not easy jams, and achieve building materials flame retardant performance requirements, ageing resistance and long service life. Indoor and buried service life can be up to 50 years, outdoor use 50 years.
    (2) kind of lightweight, convenient transportation, storage and installation, help to accelerate the progress of the projects and reduce the construction cost.
    (3) save construction cost use UPVC pipes, fittings than use the same specifications of cast iron pipe system cost low, and facilitate maintenance.
use
Applicable to within the building drainage system, in consideration of the tubing linear.thermal heat resistant and conditions can also be used for industrial drainage system, in °C below 60 temperature can use continuously? °C below in 80 can intermittent use.
2 water use rigid PVC plastic pipe and fittings
Water use rigid PVC plastic pipes and pipe is food sanitation PVC resin as main raw materials, join non-toxic specialty auxiliaries, by mixing plasticizing, extrusion, or injection into. The product conforms to the national water hygiene standards, using by interpolation cementation, the elastic sealing ring, metal variable joint etc connection.
characteristics
    (1) physical excellent performance, UPVC water-supply pipe, tube anti-impact intensity is high, the surface is smooth, fluid resistance small, emptying ability for same type steel tube, and not easily 120% scaling, long-term use of water conveyance ability not decreased.
    (2) corrosion resistance, rusty, not by the soil and water erosion sexual and physical function and corrosion damage, general life in 50 years.
    (3) small coefficient of thermal conductivity, winter use the difficult DongLie.
    (4) light weight, convenient transportation, storage and installation, labor efficiency high, help to accelerate the progress of the projects and reduce the construction cost.
use
Mainly used for residential interior supply system, instead of traditional iron pipe and fittings, and can be used in drainage, sewage forhandling corrosive fluid system. Can also be used to transfer temperature in 45 °C below the building (overhead) or direct buried the pipes
