The main components of PVC drainage pipe are polyvinyl chloride, calcium powder, stabilizer, stearic acid, paraffin, CPE, etc. Bright color, corrosion resistance, firm and durable, due to the addition of some toxic auxiliary materials such as plasticizers and anti-aging agents to enhance its heat resistance, toughness, ductility, etc., so its products generally do not store food and medicine . It is a kind of synthetic material that is well-loved, popular and widely used in the world today. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, PVC production in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, the production and consumption of PVC averages 1.4 million tons. PVC is being produced and applied worldwide with a growth rate of 4%. In recent years, the growth rate of PVC in Southeast Asia has been particularly remarkable, thanks to the urgent need for infrastructure construction in Southeast Asian countries. Mainly used for production: Prewin pvc cards; pvc OEM; pvc wire; pvc curtains; pvc coated welded wire mesh; pvc foam board, pvc ceiling, pvc water pipe, pvc skirting, etc. Plastic doors and windows, plastic bags, etc. PVC products can be found everywhere in our daily life. PVC is used to make all kinds of imitation leather, used for luggage, sports products, such as basketball, football and rugby.

Process flow of PVC drainage pipe machine / PVC pipe production line
PVC drainage pipe production process raw material + auxiliary preparation → mixing → conveying and feeding → forced feeding → conical twin screw extruder → extrusion die → sizing sleeve → spray vacuum setting box → immersion cooling water tank → ink printing machine → Crawler Traction Machine → Knife Lifting Cutting Machine → Pipe Stacking Rack → Product Inspection and Packaging
PVC drainage pipe machine / PVC pipe production line equipment function
(1) Raw material mixing: PVC stabilizer, plasticizer, antioxidant and other auxiliary materials are added to the high-speed mixer according to the proportion and process, and the material is heated to the set process temperature by self-friction of the material and the machine, and then The material is reduced to 40-50 degrees by the cold mixer; so it can be added to the hopper of the extruder. (2) Extruder part: This machine is equipped with a quantitative feeding device, so that the amount of extrusion and the amount of feeding can be matched to ensure stable extrusion of products. Due to the characteristics of the conical screw, the feeding section has a larger diameter, and the heat transfer area and shear speed of the material are relatively large, which is beneficial to the plasticization of the material. The small diameter of the metering section screw reduces the heat transfer area and the melt. The shear rate allows the melt to be extruded at a lower temperature. When the screw rotates in the barrel, the PVC mixture is plasticized and pushed to the head, so as to achieve compaction, melting, mixing and homogenization; and to achieve the purpose of exhaust and dehydration. The feeding device and screw drive device adopt frequency conversion speed regulation, which can achieve synchronous speed regulation (3). Extrusion die head part: PVC after compaction, melting, mixing and homogenization, and subsequent materials are pushed to the die head by the screw and extruded The die head is a key component of tube forming.

   (4) Vacuum shaping water tank is used for shaping and cooling of pipes. The vacuum shaping water tank is equipped with a vacuum system and water circulation system for shaping and cooling. The stainless steel tank is equipped with circulating water spray cooling. Left and right, height adjustment manual device.

   (5) The traction machine is used to continuously and automatically lead the cooled and hardened pipe material from the machine head, and the frequency conversion is used to adjust the speed.

   (6) Cutting machine: After the stroke switch is controlled according to the required length, automatic cutting is performed, and the overturning is delayed, and flow production is carried out. The cutting machine takes the fixed length switch signal as the instruction to complete the entire cutting process. The operation of the pipe is kept synchronized, and the cutting process is completed by electric and pneumatic drives. The cutting machine is equipped with a dust suction device to suck out the debris generated by the cutting in time and recycle it.

   (7) The material turning action of the material turning frame is realized by pneumatic cylinder control. The material turning frame is equipped with a limit device. After the cutting saw cuts the pipe, the pipe continues to be conveyed. After a delay, the cylinder enters the work to realize the turning Feeding action to achieve the purpose of unloading. After unloading, it will automatically reset after a delay of several seconds, waiting for the next cycle.
PVC pipe use
(1) PVC pipe means that the main raw material for making the pipe is PVC resin powder. The types of PVC pipes are generally divided according to the use of pipes: drain pipes, water supply pipes, wire pipes, cable sheath pipes ... Because the raw material formula is different, the pressure resistance of various types of pipes The indicators are different. PVC water supply pipes and water supply fittings are used in water supply projects of buildings. PVC drain pipe is used for sewage ...

How to distinguish the quality of PVC pipes

   (1) First look at the surface finish and whiteness.

   (2) Throwing the sample, the person who is easy to break is generally a high-calcium product, of course, if it meets your requirements, the price is ok.

   (3) Take the sample and step on the edge of the pipe with your feet to see if it can crack or the elongation at break after cracking.

   (4) The weather resistance is quite troublesome. The most direct way is to get high temperature and high heat, which takes time to test.
