Polyvinyl chloride PVC is the biggest characteristic of flame retardant, so is widely used in fire protection applications.But the polyvinyl chloride PVC in the process of combustion will release hydrogen chloride and other toxic gases, such as dioxin.

Polyvinyl chloride PVC combustion can be divided into two steps.In 240 C to 340 C before burning decomposition of hydrogen chloride gas and alkadiene contain a double bond, and then in 400-470 C carbon burning.


~~~~~Several kinds of common PVCpipes:~~~~~
1. PVC Water Pipe:
Overview:
PVC water pipe is health grade PVC resin as the main raw material, adding quantitative stabilizer, lubricant, filler, toner, etc., the plastic extruder extrusion molding and injection molding machine, through cooling and solidifying, finalize the design, testing, packaging process to produce a kind of water supply pipe.

Specifications:
PVCpipe size has 20,25,32,40,50,63,75,90,110,125,140,160,180,200,225,250,280,315,355,400,450,500,630,720,800etc.

For PVC hoses - as the nominal pressure, pressure of said expressed in Mpa.Nominal pressure regulation is 0.63 Mpa, 0.8 Mpa, 1.0 Mpa, 1.25 Mpa, 1.6 Mpa, etc.

Minimum diameter of the pipe for each pressure area: 0.63 Mpa pipes, the minimum diameter is 63 mm, manage the minimum diameter of 50 mm 0.8 Mpa, 1.0 Mpa pipes, the minimum diameter of 40 mm, 1.25 Mpa pipes, the minimum diameter is 32 mm, 1.6 Mpa pipes, the minimum diameter of 20 mm and 25 mm.Pipe length is 4 m, 6 m, 8 m.

PVC formability:
1. Amorphous materials, hygroscopicity, liquidity is poor, in order to improve the liquidity, prevent bubbles and appropriate drying in advance.

2. Easy to decompose, especially at high temperature in contact with the steel and copper are more likely to break down decomposition temperature 200 degrees c .Molding temperature range is small, must be strictly controlled temperature for the material.

3. Use of screw injection machine and direct the nozzle aperture should be larger, in case of blind Angle hysteresis material.

4. Mould gating system should be thick, the appropriate gate section, mould should be cooling, mould temperature 30 to 60 degrees, the material temperature 160-190.
