Rotomolding And Injection Molding Process Of PE Gas Pipe

Rotomolding and injection molding process of PE gas pipe

PE gas pipes are used a lot in daily life and have a wide range of application fields. The product knowledge about this material must be something that everyone is not particularly familiar with. The rotomolding and injection molding process of PE gas pipes, let’s have a brief understanding:

The rotomolding and injection molding process of PE gas pipe is that the material using this processing method is generally crushed into powder material, which is melted and flowed in the thermal cycle.

The comparative test of the wear resistance of large-diameter PE pipe HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transportation, HDPE pipes have better wear resistance than steel pipes, which means that HDPE pipes have a longer service life and better economy.

Rotomolding uses two types of PE: general-purpose and cross-linkable. The product has high impact and small warpage, and its melt index is generally in the range of 3-8. Higher MI grades are generally not suitable because they do not have the impact and environmental stress crack resistance expected of rotomolded products. HDPE has countless applications, ranging from reusable thin-walled beverage cups to 5-gsl cans, which consume 1/5 of domestically produced HDPE. Injection molding grades generally have a melt index of 5-10. There are grades with toughness and lower fluidity and higher fluidity grades with processability.

The introduction in the above article is about the introduction of the rotomolding and injection molding process of the PE gas pipe. The use of a product should be based on the product knowledge of the product, so as to avoid problems in the use process and do not know how to solve it, so the operators and manufacturers When using a product, we must pay attention to understanding the process and knowledge of the product. The steel mesh skeleton pipe polyethylene composite pipe is a mesh skeleton formed by spirally winding high-strength steel wire left and right as the reinforcement, high-density polyethylene (HDPE) as the matrix, and the steel wire skeleton is combined with the high-performance HDPE modified bonding resin. A new type of pipe in which the inner and outer layers of high-density polyethylene are tightly connected together.

The pe gas pipe is polymerized by monomer ethylene. Due to the different polymerization reaction conditions such as pressure and temperature during polymerization, resins of different densities can be obtained. Therefore, there are high-density polyethylene, medium-density polyethylene and low-density polyethylene. Of points. When processing different types of PE pipes, according to the different application conditions, choose the corresponding resin grades, and the requirements for extruders and molds are also different. PE drainage pipe polyethylene PE pipe due to its unique advantages is widely used in building water supply, building drainage, buried drainage pipe, building heating, gas transmission pipe, electrical and telecommunications protection casing, industrial pipe, agricultural pipe, etc. . It is mainly used in the fields of urban water supply, urban gas supply and farmland irrigation
