PE gas pipe rotomolding and injection molding process

PE gas pipe in the life of many uses now, a wide range of applications, product knowledge about this material must not be particularly familiar with the PE gas pipe rotomolding and injection molding process, a simple understanding:

PE gas pipe rotomolding and injection molding process is the use of this processing method of the material is generally crushed into powder material, so that it melts and flows in the thermal cycle.

Large diameter pe pipe HDPE pipe and steel pipe abrasion resistance comparison test shows that the abrasion resistance of HDPE pipe is 4 times that of steel pipe. In the field of slurry transportation, compared with steel pipe, HDPE pipe has better abrasion resistance, which means that HDPE pipe has a longer service life and better economy.

Rotomolding uses two types of PE: general purpose and cross-linkable. Products with high impact and low warpage generally have a melt index range of 3-8. Higher MI grades are generally not suitable because they do not have the impact and resistance to environmental stress cracking that is desired in rotomolded products. hdpe has countless applications ranging from reusable thin-walled beverage cups to 5-gsl cans, and consumes 1/5th of the hdpe produced domestically. Injection molding grades generally have a melt index of 5 to 10, and there are lower fluidity grades with toughness and higher fluidity grades with processability.

The above text is about PE gas pipe rotomolding and injection molding process, the use of a product should be based on product knowledge to use, so as to avoid problems in the use of the process do not know how to solve, so operators and manufacturers in the use of a product must pay attention to understand the product process and knowledge. Wire mesh skeleton pipe polyethylene composite pipe is a high-strength steel wire around the spiral winding molding mesh skeleton as a reinforcing body, to high-density polyethylene (HDPE) as a substrate, and high-performance HDPE modified binder resin will be the steel wire skeleton and the inner and outer layers of high-density polyethylene is closely linked together in a new type of pipe.

PE gas pipe by the monomer ethylene polymerization, due to different conditions of polymerization reaction in the polymerization due to pressure, temperature, etc., can be derived from different density of the resin, and thus there are high-density polyethylene, medium-density polyethylene and low-density polyethylene points. In the processing of different types of PE pipe, according to the different conditions of its application, the selection of the corresponding resin grade, while the requirements of the extruder and molds are also different. pe drainage pipe polyethylene PE pipe because of its own unique advantages are widely used in building water supply, building drainage, buried drainage pipe, building heating, gas transmission, electrician and telecommunication protection casing, industrial pipe, agricultural pipe and so on. It is mainly used in the fields of urban water supply, city gas supply and farmland irrigation.
