LDPE, Also known as high-density polyethylene, it generally refers to plastic packaging film. For example: packaging bag liner film, food packaging film, daily necessities packaging film, plastic greenhouse film. This type of film is mostly in its original color, and there are also light blue and gray black options. It is best to separate the color […]

Characteristics of HDPE pipe production line The PE pipe production line is designed with a spiral die for HDPE and PP large-diameter thick walled pipes. This die has the characteristics of low melt temperature, good mixing performance, low mold cavity pressure, and stable production The PE pipe production line adopts proprietary technology for sizing and

Introduction of each part of the PVC pipe production line (1) Raw material mixing: It is the process of adding PVC stabilizers, plasticizers, soothing reactants and other auxiliary materials into a high-speed mixer in proportion and sequence according to the process. The materials are heated to the set process temperature through self friction between the

The usage methods of different plastic extruders are generally different, but the normal shutdown operation is still similar. We will briefly compile a document on the normal shutdown sequence of conventional twin-screw plastic extruders, as follows: Firstly, we need to stop feeding the plastic extruder. Conventional twin-screw plastic extruders have a feeding machine or feeding

There are many production methods for plastic granulation nowadays, among which the extruder water-cooled strip granulation production line is a relatively common production method. Our company has prepared some technology for you so that everyone can quickly identify and implement simple abnormalities and countermeasures when using a water-cooled strip granulation line, in order to quickly

(1) The outer surface of plastic pipes is rough Adjust the process temperature: reduce the cooling water temperature, and the suitable cooling water temperature for P pipe is 20-25 ℃; Check the waterway for blockages or insufficient water pressure; Check if the heating coils such as the barrel and head are damaged; Adjust the inlet flow

4. Start up production A. When heating each section, it should be heated in stages, that is, first heating the temperature of each section to 120 ℃, holding it constant for 30 minutes, then heating it to 160 ℃, holding it constant for 15 minutes, and heating it to the process temperature. B. After the

1.Extrusion principle The plastic processing industry is a highly comprehensive and technological industry. It involves aspects such as polymer chemistry, polymer physics, interface theory, plastic machinery, plastic processing molds, formula design principles, and process control. The extrusion theory mainly studies the movement and variation patterns of plastics in an extruder. The relationship between the three

To gain a deeper understanding of PVC pipes, we can delve into their material characteristics and advantages in detail   Material characteristics: Lightweight The lightweight material of PVC pipes makes the handling and loading and unloading process very convenient, which can greatly reduce transportation costs and installation construction intensity Excellent chemical resistance: PVC pipes have

HDPE, it is an abbreviation for high-density polyethylene, also known as low-pressure polyethylene. It is a thermoplastic resin with high crystallinity and a semitransparent non-polar surface. In terms of physical properties, its operating temperature can reach 100℃ and melting temperature can reach 120-160℃. It has good heat and cold resistance, as well as high rigidity
