 As we all know PE sheet and stainless steel are different materials, so how to do the two bonding?

As we all know, PE sheet belongs to one kind of engineering plastic sheet, which can be used in many industries. In order to better ensure its application performance, we need to pay special attention to the selection of raw materials in the production of PE sheet. So what do we need to pay attention to the selection of raw materials for PE sheet?

PE sheet of good performance in a variety of applications will be able to highlight, because PE sheet has good performance so we think of the first application of many times the material is also PE sheet, it can be said that PE sheet has come into our lives, everywhere glow.　　PE sheet points with high toughness, tensile, wear-resistant performance and other characteristics.

  The way to change the oxidation reaction of polyethylene sheet is to add reagents and antioxidants with anti-ultraviolet function, such as ultraviolet absorber or carbon black can significantly improve its resistance to aging changes.    PE sheet is odourless, non-toxic, feels like wax, has excellent low-temperature resistance, is a kind of thermoplastic resin with high crystallinity, but under the action of ultraviolet rays in the atmosphere and sunlight, it will be aged, discoloured, cracked, brittle or chalked, and lose its mechanical properties.    In the mouldin

Polypropylene (PP) is a common plastic material with a variety of uses, mainly including the following aspects:Packaging: polypropylene is widely used in food packaging, pharmaceutical packaging, daily necessities packaging and other fields. For example, polypropylene can be made into food bags, bottles, containers, etc., with good heat resistance and sealing.Textiles: PP Sheet is widely used in the manufacture of various textiles, such as carpets, clothing, household goods and so on.

a, Appearance check    Check the appearance of PE sheet, including such items as: flatness of the sheet, uniformity of colour, surface finish, colour, cutting area, thickness, good quality sheet generally these indicators to a higher level.b, enterprise technology certification    In general, the strength of the more powerful indebtedness table of the enterprise, more have a number of certifications, for example, through the ISO9001 quality system certification, the national industry industry standards, with PE sheet processing equipment, complete physical and chemical test

What Is PP Board？PP board, the full name of polypropylene board, is a semi-crystalline plate, its core raw material is polypropylene resin.The characteristics of this plate are distinctive, it is light, uniform thickness, smooth surface like a mirror, not only high mechanical strength, excellent heat resistance, but also has excellent chemical stability and electrical insulation, and completely non-toxic. It is worth mentioning that compared with PE board, PP board has higher hardness and better melting point.

Food Grade PP Boards are widely used in food processing, packaging and storage due to their good mechanical properties, chemical stability, heat resistance and easy cleaning. Ensuring that the selected food-grade PP sheets are of reliable quality is essential to ensure food safety. Here are some key considerations for judging the quality of food-grade PP sheets:1. Material certificationThe materials used in high-quality Food Grade PP Boards strictly comply with hygiene and safety standards during the production process and are suitable for direct contact with food.

The main reason for the popularity of HDPE sheet is that HDPE sheet has very good abrasion resistance, and the molecular weight is very large, and the material's abrasion resistance and impact resistance are very good. It has good heat and cold resistance, good chemical stability, also has high rigidity and toughness, good mechanical strength. Dielectric properties, resistance to environmental stress cracking is also good. Melting temperature 220~260 C.

PP Board has a wide range of uses, including the following aspects:Industrial field:Chemical industry: Used to make chemical containers, pipes, valves, etc., because of its good corrosion resistance, can withstand the erosion of a variety of chemical substances.For example, in chemical plants, PP boards can be made into storage tanks for strong acids and bases.Electronic industry: It can be used as parts of electronic equipment, such as the backing plate of circuit boards, packaging materials of electronic components, etc.Because it has certain insulation properties, it can ensure the safe ope
