Solar backsheet film coating machine

Solar cell backsheet is also called solar cell backsheet film, photovoltaic backsheet, photovoltaic backsheet film, and solar backsheet.
It is widely used in solar cell (photovoltaic) components. It is located on the back of the solar panel. It protects the solar cell components from water vapor erosion in outdoor environments, blocks oxygen and prevents internal oxidation of the components. It has reliable insulation, water resistance, and aging resistance. High and low temperature resistance, corrosion resistance. It can reflect sunlight and improve component conversion efficiency; it has high infrared reflectivity and can reduce component temperature.
Classification of photovoltaic backsheet
1. Glue-coated composite backsheet film
The fluorine film or EVA film is compounded on both sides of the PET polyester film to form a three-layer structure.
2. Coating back sheet film
The PET polyester film is coated with fluororesin on both sides and dried to solidify into a film.
3. There are also a few manufacturers that use the cross-linking reaction method to react with cross-linking agents on both sides of PET to produce composite films or EVA films.

Electronic grade protective film coating machine

Scope of use of PET protective film: suitable for all types of screen protection, protection of computer keyboards during the production process, and protection with low static electricity requirements on the surface. LCD, LCM screen surface protection and anti-seismic protection, applied to the surface protection of electronic screens, instrument surfaces, automobile instruments, casings, etc., optical sheets, optical resin plates, etc.
This coating equipment uses micro-concave MG (or direct scraping COMMA or squeeze Slot-die) to coat the adhesive (pressure-sensitive adhesive PSA or silicone Silica gel) on the surface of the PET film. After hot air drying, UV curing, and then composite protection Film or direct winding mechanical equipment;

Base material: rigid PVC (0.15~0.4mm)
This coating equipment is a mechanical equipment that coats PVDC aqueous solution on the surface of the hard PVC film with a mesh (or extrusion slot-die), dries with IR and hot air, and then directly winds up or winds up the composite aluminized film;

Silicone cloth coating machine, silicone heat sink calendering machine

Thermal conductive silicone cloth equipment (WS-TB-13-01)
Thermal conductive silicone cloth is a silicone polymer elastomer reinforced with glass fiber or BOPI film as the base material. It is also called thermally conductive silicone cloth and tear-resistant silicone cloth. This silicone cloth can effectively reduce the heat dissipation of electronic components. Thermal resistance between devices and electrical insulation, high dielectric strength, good thermal conductivity, high chemical resistance, can withstand high voltage and short circuit caused by metal parts puncture, it is a replacement for traditional mica and Silicone grease is an excellent thermal conductive insulating material.
Common colors are white and pink. The thickness ranges from 0.18mm/0.23mm/0.28mm. It is used for filling between the heat source and the heat dissipation module or shell, and for insulation filling between the live heating element and the shell.
Thermal conductive silicone sheet equipment (WS-TB-13-02)
Thermal conductive silicone sheet is a thermal conductive medium material synthesized through a special process using silica gel as the base material, adding various auxiliary materials such as metal oxides, and is specially produced for the design and production of heat transfer using gaps. It can fill gaps and complete heating parts. The heat transfer between the heat dissipation part and the heat dissipation part also plays the role of insulation, shock absorption, sealing, etc., which can meet the design requirements of miniaturization and ultra-thin equipment. It is very technological and usable, and has a wide thickness range. An excellent thermally conductive filling material. Thermal conductive silicone sheets can be divided into ordinary thermally conductive silicone sheets, strong adhesive thermally conductive silicone sheets, silicone tape-backed thermally conductive silicone sheets, and glass fiber thermally conductive silicone sheets in the middle. At present, the thermal conductivity of domestic thermal silica gel sheets ranges from 0.8W/M.K~8.0W/M.K.
Used for control motherboards of electronic and electrical products, pads and foot pads inside and outside motors, electronic and electrical appliances, automotive machinery, computer hosts, laptops, DVDs, VCDs and any materials that require filling and cooling modules.
