Introduction Of Polyester Film Sandpaper And Pet Film Sanding Disc
1. Production Process
Polyester film sandpaper is a high-performance sandpaper that uses polyester (PET) film as the base material, and goes through processes such as glue coating, abrasive covering, curing, cutting, etc. Its production process is as follows:
(1) Glue coating: The polyester film is cleaned and dried, and then coated with a layer of adhesive, usually phenolic resin or acrylic resin, to enhance the adhesion and water resistance of the film.
(2) Abrasive covering: The glued polyester film is evenly sprinkled with abrasive particles, usually alumina, silicon carbide, diamond, etc., to provide the cutting and wear resistance of the sandpaper.
(3) Curing: The polyester film covered with abrasive is treated by heating, pressure, etc., to form a strong chemical or physical bond between the adhesive and the abrasive, to enhance the stability and durability of the sandpaper.
(4) Cutting: The cured polyester film is cut into different sandpaper products according to the specified size and shape, such as discs, belts, sheets, etc., and different holes and edges are processed according to the needs, to fit different polishing equipment and processes.
2. Product Features
Polyester film sandpaper has the following features:
(1) High strength: Polyester film has high tensile strength and tear resistance, which can withstand high-speed polishing and bending without breaking or deforming.
(2) High transparency: Polyester film has high optical transparency and refractive index, which can clearly display the state and effect of the polished surface, and facilitate the control of the polishing process and quality.
(3) High stability: Polyester film has high temperature resistance and chemical resistance, which can maintain its physical and chemical properties unchanged in high temperature, humidity, acid and alkali and other harsh environments, and not easy to age or discolor.
(4) High efficiency: The abrasive covered on the polyester film has high cutting force and wear resistance, which can quickly remove the material from the polished surface, and maintain its sharpness without dulling, thus improving the polishing efficiency and quality.
(5) Low dust: The adhesive covered on the polyester film can effectively fix the abrasive, reduce the dust generated during the polishing process, thereby reducing the pollution and harm to the environment and human body.
High adaptability: Polyester film has high flexibility and plasticity, which can adapt to different polishing equipment and processes, such as wet polishing, dry polishing, hand polishing, machine polishing, etc., to meet different polishing needs and conditions.
3. Product Applications
Polyester film sandpaper is widely used in various fields, such as:
(1) Automobile manufacturing: Polyester film sandpaper can be used for polishing, buffing, repairing and other processes of automobile surface, to improve the appearance quality and durability of automobile.
(2) Metal processing: Polyester film sandpaper can be used for deburring, rust removal, oil removal, oxide layer removal and other processes of metal materials, to improve the surface quality and performance of metal.
(3) Wood processing: Polyester film sandpaper can be used for sanding, coating, repairing and other processes of wood materials, to improve the surface smoothness and beauty of wood.
(4) Glass processing: Polyester film sandpaper can be used for sanding, cutting, engraving and other processes of glass materials, to improve the surface gloss and transparency of glass.
(5) Plastic processing: Polyester film sandpaper can be used for sanding, cleaning, decontamination and other processes of plastic materials, to improve the surface quality and stain resistance of plastic.
4. Product Advantages and Disadvantages
Compared with other types of sandpaper, polyester film sandpaper has the following advantages and disadvantages:
Advantages
(1) Low cost: Polyester film is a cheap and easy-to-obtain material, so the production cost of polyester film sandpaper is relatively low.
(2) Long life: Polyester film has high durability and stability, so the service life of polyester film sandpaper is relatively long.
(3) Good effect: Polyester film has high transparency and strength, so the polishing effect of polyester film sandpaper is relatively good.
Disadvantages
(4) Prone to static electricity: Polyester film has high static electricity, so polyester film sandpaper is prone to generate static electricity during use, which may affect the polishing effect or damage sensitive electronic equipment.
(5) Prone to soften: Polyester film has low temperature resistance
