PVC Insulated Pipe Production Line
PVC (full name Polyvinylchlorid), the main component of PVC, in addition to other ingredients to enhance its heat resistance, toughness, ductility, and so on. The top layer of the surface mask is lacquer. The main ingredient in the middle is PVC, and the bottom is the back coated adhesive.
The rubber tube structure is usually divided into the inner layer, the outer layer and the skeleton layer (or the middle layer). The inner layer directly bears the wear and erosion of the transport medium, and the outer rubber layer protects the inner part of the rubber hose from damage and erosion by the external environment. The skeleton layer is the pressure bearing layer of the rubber hose, giving the strength and rigidity of the pipe body. The working pressure of the hose depends on the material and structure of the framework.
The production process of raw material preparation, mixing, + auxiliary conveying, forced feeding, conical twin-screw extruder, extrusion mould, sizing sleeve, spray vacuum setting tank and immersion cooling water tank, ink printing machine, crawler machine, cutter, pipe cutting machine and finished product packaging testing pile frame.
PVC is being produced and applied around the world with a growth rate of 4%. The growth rate of PVC in Southeast Asia is particularly significant, thanks to the urgent need for infrastructure construction in Southeast Asia. In the material that can produce the three-dimensional surface mask.
The essence of PVC insulating pipe is a vacuum plastic film, which is used for surface packaging of various panels. Therefore, it is also known as decorative film and adhesive film, which is applied to many industries, such as building materials, packaging, medicine and many other industries. The building materials industry accounted for the largest proportion, sixty percent, followed by the packaging industry, and a number of other small range of applications.
