PVC(Polyvinylchloride,PVC)Profile Polyvinylchloride,the main ingredients of PVC,bright color,corrosion-resistant,durable,plasticizers,anti-aging agent of some toxic auxiliary materials in the manufacturing process to enhance its resistanceheat resistance,toughness,ductility,its products generally do not store food and medicine.
PVC is the favorite in today's world,is quite popular and is also widely used as a synthetic material.The second highest global use in a variety of synthetic materials.According to statistics,in the year 1995 alone,the production of PVC in Europe there are about five million tons,while its consumption was 5.3 million tons.PVC production and consumption in Germany,an average of 1.4 million tons.PVC is a growth rate of 4%in the worldwide production and application.PVC growth rate in Southeast Asia particularly significant,thanks to the Southeast Asian countries have pressing needs of infrastructure construction.Can produce a three-dimensional table mask material,PVC is the most suitable material.The PVC(polyvinyl chloride),monomer structure Simple as CH2=CHClpvc PVC material is highly versatile,with good processing performance,low manufacturing costs,resistance to corrosion,insulation,and other good features,mainly for the production of:Puri text pvc card;pvc OEM;of pvc wire;pvc curtain;pvc coated welded wire mesh;pvc foam board,pvc ceiling,pvc pipes,pvc baseboard and threading pipe,cable insulation,plastic doors and windows,plastic bags and other aspects.Can be seen everywhere in our areas of daily life PVC products.PVC is used to make all kinds of imitation leather for bags,sports products,such as basketball,football and rugby.Can also be used for making uniforms and special protective equipment belt.
PVC pipe production line
(1),the raw materials are mixed:the PVC stabilizers,plasticizers,antioxidants and other excipients,such as,in proportion,process successively added to the high-speed mixer,so that the material was allowed to warm to the setting process temperature since the friction materials and machinery,and then cold mixing machine the material was dropped to 40-50 degrees;This may be added to the hopper of the extruder.
(2),the extruder section:The machine is equipped with a dosing device,so that the extrusion amount and the feeding amount can be matched,ensuring products stable extrusion.Due to the characteristics of the conical screw,the feed section has a larger diameter,the heat transfer area and a shear rate of the material is relatively large,beneficial material plasticization,the screw diameter of the metering section is small,reducing the heat transfer area and on the melt shear rate,so that the melt can be extruded at the lower temperature.Rotation of the screw in the machine barrel,the PVC compound plasticized push the nose,so as to achieve compaction,melting and kneading a homogenizer;and achieve the purpose of the exhaust gas,dehydration.The feeding device and screw drive unit using VVVF synchronous speed.
(3),an extrusion die head portion:by compaction,melting and kneading the homogenized PVC subsequent material pushed by the screw die,the extrusion die is a pipe molding related construction member.
(4),vacuum sizing tank stereotypes for pipes,cooling,vacuum sizing tank is equipped with vacuum system and water circulation system for shaping and cooling,stainless steel cabinet,circulating water spray cooling,before and after vacuum sizing tank is equipped with a mobile device left and right,high and low regulation manual device.
(5)tractor for Wooden Flooring Production Line continuous,automatic pipe cools and hardens lead out from the head office,frequency control.
(6),the cutting machine:automatically cut according to the requirements of the length of the control by the travel switch,and delay the turning frame,the implementation of the water production,the cutting machine to be the permanent employment Wood and Plastic Extrusion Line switching signal for command to complete the cutting of the whole process in the cutting process,and The pipe running in sync,the cutting process is completed by the electric and pneumatic drive,the cutting machine is equipped with a suction device,the cutting debris generated in a timely manner sucked out,and recovered.
(7),tilter,stirring up action by the cylinder is controlled by the gas path to achieve turn feed erected a limit devices,cutting saws cut pipe,tubing continue to transport by the delay,the cylinder into the working to achieve turn material action,reached unloading purposes.By the delay for a few seconds after the discharge is automatically reset to wait for the next cycle.
