① Hand polishing tools. Manual polishing mainly involves using sandcloth to wrap wooden blocks (rubber blocks) or water sandpaper to wrap wooden blocks (rubber blocks) for polishing. Wood block sanding cloth is mainly used for dry grinding of putty layer, while water sanding paper wrapped rubber block is mainly suitable for water grinding of fine putty and intermediate coating paint film. When using manual polishing tools, they are usually paired with tools such as a scraper, brush, and cotton yarn. If dry grinding putty, the burrs on the surface of the putty layer can be removed with a scraper first, and the rough scratches can be smoothed before polishing.
Dry grinding has a lot of dust, while water grinding has no dust, high efficiency, and good quality. Therefore, water grinding should be advocated Mechanical polishing tools. Mechanical grinding tools include pneumatic grinding machines, electric grinding machines, etc. The pneumatic ash grinder has high efficiency, good quality, and safe use. Currently, there are domestic pneumatic ash grinder varieties such as F66, F32, N3, M2, etc., which are favored by users. Electric ash grinding machines have low noise, light vibration, less dust flying, and higher quality than pneumatic ash grinding machines.
PC resin is used in car lighting systems, instrument panel systems, and interior decoration systems, as front lampshades, reinforced front and rear fenders, reflective frames, door frame covers, operating rod covers, choke plates, PC is used as junction boxes, sockets, plugs and sleeves, gaskets, television conversion devices, communication cable connections under telephone line brackets, switch boxes, telephone exchanges, distribution panel components, relay housings, etc, PC can be used as low load parts for household electrical motors, vacuum cleaners, hair washers, coffee machines, toasters, power tool handles, various gears, worm gears, shaft sleeves, guide gauges, and refrigerator shelves.
Dalian metal plastic coating PC is a storage medium for optical discs. PC bottles (containers) are transparent, lightweight, and have good impact resistance. They can withstand washing with a certain amount of high-temperature corrosive solution and are used as recyclable bottles (containers). PC and PC alloys can be used for accounting racks, casings and auxiliary equipment, as well as printer parts. Modified PC is resistant to high-energy radiation sterilization, steaming and baking disinfection, and can be used for blood sampling instruments, blood oxygenators, surgical instruments, kidney dialyzers, etc. PC can be used as a helmet and safety helmet, protective mask, sunglasses, and sports goggles. PC film is widely used for printing charts, pharmaceutical packaging, and film commutators.
