Advantages of various roller surface coating in the Bi-oriented Stretch Film

Ceramic coatings

Ceramic coatings include alumina, titania, zirconia, chromium oixde, silicon carbide, silicon nitride, and boron carbide, as well as oxides of many of these materials. It can provide wear protection to guide rollers for films, fibers, paper and cardboard. In recent years, it has also been active in biomaterials. Usually the plasma coatings system to spray ceramic powder material with the temperature range from 18000℃ to 30000℃. Main properties of ceramic coatings include high chemical corrosion resistance, anti-static, excellent wear resistance, mirror surface finished, oxidation resistance, excellent electrical insulation, high hardness. Ceramic coating apply to CFRP, aluminum, steel roller.

Non-stick wear coatings

Use a kind of special polymer combined with metal powder by plasma coatings process which can form dural layer extremely wear resistant and non stick functional surface for hot melt glue. Non-stick wear coatings widely used in adhesive tape, sanitary napkins, diaper, film industry. Non-stick wear coatings main properties include prevent adhesive build-up, web tension control, superior wear proformance, superior anti-corrosion, reduce roller/parts work noise. Non-stick wear coatings apply to CFRP, aluminum, steel roller.

Tef lon coatings

Low friction fluoropolymer with outstanding chemical resistance and weathering resistance. It has excellent electrical insulating properties. It can also solve the contamination problem for ink, plastic, water-based glue. Tef lon coatings main properties include smooth finished surface, low friction, high temperature applications up to 240℃, easy clean. Tef lon coatings apply to CFRP, aluminum, steel roller.

Tungsten carbide coatings

Tungsten carbide hard facing coatings are a kind of coating with high hardness, erosion resistance, excellent wear resistance up to HV 1200. Coatings exhibit a strong metallurgical bond with the substrate. It mostly used in film, paper-making, turbine blade, cardboard industry. Tungsten carbide coatings main properties include excellent corrosion and wear resistance, high hardness, high-conductivity, scratch resistance, impact resistance, heat and oxidation resistance, ultra mirror surface finished Ra 0.02um.

Stainless steel coatings

Stainless steel is an iron-based alloy that contains an appreciable percentage of chromium and nickel. It enhanced surface quality as well as increased corrosion and wear resistance. It mostly used to spray onto CFRP roller surface what can make it like a 'steel roller' with lightweight. Stainless steel coatings main properties include corrosion resistance, durable, hygienic, temperature resistance, mirror surface finished, apply to CFRP roller.
