The diameter of the discharge port is mm, and the length of the discharge port is mm.
Melt Index. Extrusion discharge part requirements, discharge port diameter mm; The length of the discharge port is mm; Barrel diameter mm; Barrel length: 152 mm; piston head diameter mm; Piston head length in mm.
The ambient temperature is 10 -40; Ambient relative humidity.
30%-80%; There are no corrosive media around, and it is correctly installed and adjusted to the level on a solid foundation. No strong air convection; There is no vibration and no strong magnetic field interference around.

PE is divided into LDPE (high-pressure polyethylene), HDPE (low-pressure polyethylene), and LLDPE (linear polyethylene).
LDPE is relatively soft, has good toughness, and can blow thick films; HDPE is relatively hard and can be injection molded and made into pipes; LLDPE is mainly blown film.
I don't know much about LCP either, so I can't help you. Please refer to it.

Lipolysis is actually the flow rate of plastic. The higher the lipolysis, the faster the flow rate.
Melt Mass-Flow Rate (MFR, Melt Mass Flow Rate), also known as Melt Index (MI, Melt Index), is the number of grams of melt that flow out of the resin melt through a standard capillary within a certain period of time (generally 10min) in a standardized extrusion plastometer at a certain temperature and pressure, in g 10min.
The melt flow rate is an important reference for the selection of plastic processing materials and grades, which can make the selected raw materials better adapt to the requirements of the processing technology, and improve the reliability and quality of the products.

It is the melt index, which is the melt flow index.
It is an indicator of the processing performance of the plastic, and the high melt index is generally used for injection molding, and the low one is extruded.
Melt index, MI, plastic fluidity index, the higher the value, the better the plastic fluidity.
Generally, the melting index of PP is in the low melt index PP, which can be used to extrude pipes and sheets.
Drawing; Medium melt index PP can be used for injection molding and blown film; High melt index PP can be used for injection molding of large, thin-walled products.

It should be the melt index, that is, the melt index, also known as the melt flow rate, which is an indicator of fluidity, and the larger it is, the better the fluidity.
-
It should be the melt index, that is, the melt flow index, which is an index that reflects the processing performance of plastics.

The diameter of the discharge port is mm, and the length of the discharge port is mm.
The melt index extrudes the discharge part and requires that the diameter of the discharge port is mm; The length of the discharge port is mm; Barrel diameter mm; Barrel length: 152 mm; piston head diameter mm; Piston head length in mm.
The ambient temperature is 10 -40; The relative humidity of the environment is 30%-80%; There are no corrosive media around, and it is correctly installed and adjusted to the level on a solid foundation. No strong air convection; There is no vibration and no strong magnetic field interference around.

Kiss! Hello, happy to answer your <>
Pro-PPR plastic lipolysis is generally the abbreviation of English random copolymer polypropylene (polypropylene-random). It is commonly known as type III polypropylene. PPR pipe is a replacement product of galvanized pipe, UPVC water supply tung fuel pipe, aluminum-plastic pipe, PE pipe, PE-X pipe and PE-RT pipe.
Because it uses random copolymerization technology, the strength and high temperature resistance of polypropylene are well guaranteed, so that it has become the main force of water pipe materials. 1. Health and environmental protection. Polypropylene is an environmentally friendly material that can be used for drinking water transportation.
2. The joint is connected with hot melt, which is integrated into a wheel, 100% leakage, and other materials are connected with wire mouth, which is inferior in impermeability and avoids the toxicity of glue bonding. PPR water pipe, PPR water pipe 3, small transmission resistance. 4. Cheap and moderate.
5. It can be used for 50 years when it is produced and used according to the national standard GB T18742. PPR is the abbreviation of type 3 polypropylene, which adopts the method of hot melt welding, has special welding and cutting tools, and has high reliability. It's also economical.
The insulation performance is also very good, and the pipe wall is also smooth! Generally, ** is 4-8 yuan per meter (4 points). Joints for inner and outer wires are not included.
PPR pipe, officially known as random copolymer polypropylene pipe, is currently the most used water supply pipe in home improvement projects. Hope mine can help you <>
