Recently, the Provincial Department of Finance, the Provincial Department of Science and Technology, and the Provincial Intellectual Property Office jointly issued 2012 annual funding to apply for a special fund for foreign patents. Jiashan County, Zhejiang Changsheng Sliding Bearing Co., Ltd. was granted lead-free self-lubricating bearings and its production methods (PCT/ CN2008/071081) Canadian Patent Application Funding. It is understood that a lead-free self-lubricating bearing and its manufacturing methods overcome the disadvantages of the friction bearing plastic layers of composite bearings that are not suitable for use in machinery manufacturing industries such as automobiles, food, pharmaceuticals, home appliances, offices, and beverages. The utility model has the advantages of simple structure, good use effect, long service life, simple and reasonable manufacturing process and the like.
PPGI/PPGL(prepainted galvanized steel /prepainted galvalume steel )is also known as pre-coated steel,color coated steel, coil coated steel, color coated steel,pre pianted steel sheet,The PPGI steel coil/sheet made of cold-rolled steel sheet and galvanized steel sheet, subjected to surface pretreatment (degreasing, cleaning, chemical conversion treatment), coated in a continuous manner, and baked and cooled to form a product. Coated steel has light weight, beautiful appearance and good anti-corrosion performance, and can be directly processed.
Color coated steel coil is mainly divided into three parts: construction, household appliances and transportation. Building is generally used to build the roof, wall and door of industrial and commercial buildings such as steel structure workshop, airport,warehouse and freezer. Household appliances are used in the production of refrigerators and large air conditioning systems, freezers, toasters, furniture, etc. Transportation industry is mainly used for oil pan, automobile interior parts, etc.
PPGI is a product made of cold-rolled steel coil and (aluminum) Galvanized Steel Coil after surface chemical treatment, coating (roll coating) or composite organic film (PVC film, etc.), and then baking and curing. This product is produced by the manufacturer in coils on the continuous production line, so it is also called prepainted steel coil. It not only has the properties of high mechanical strength and easy forming of steel materials, but also has good decoration and corrosion resistance of coating materials.
