Teflon high-temperature cloth or Teflon high-temperature cloth is a kind of fiber cloth made of glass fiber yarn with excellent prepreg performance, using polytetrafluoroethylene (also known as plastic king) moisturizing lotion as raw material. It is a new polymer material with excellent performance and multi-function.
Due to its various excellent characteristics, Teflon high-temperature cloth is widely used in Airlines, paper industry, food, environmental protection, printing and dyeing plants, clothing, chemical plants, laminated glass, pharmaceuticals, electronic equipment, insulation, engineering buildings (ceiling membrane structure engineering needle punched non-woven fabric), sand wheel slice cutting, mechanical equipment and other industries. It can be used for anti-corrosion packaging, lining and gasket, rubber conveyor belt, high-frequency polyimide film, building film materials, insulation materials, conveyor belt of microwave dryer, hose compensator, wear-resistant materials, etc.
Several common problems in identifying the quality of Teflon high temperature cloth adhesive tape:
1. the bright surface mainly depends on the quality of Teflon epoxy resin. For a good adhesive tape, the key is to use imported Teflon. The adhesive tape looks bright and has a strong texture. On the surface, the stronger the texture, the better the quality of the adhesive tape; The pure domestic Teflon coating has no gloss.
2. there is no defect on the surface, which is mainly determined by the production process. Bubbles on the surface. grain. The less the glue marks and various defects, the higher the quality of the tape. Because many of these defects may be immediately reflected in the fabric, more serious fabric damage.
3. there is no scratch on the surface. The bonding machine carries obvious scratches. No matter how big or small, in the whole application process in the future, the service life will be reduced because the scratches are easy to crack. Therefore, high-quality adhesive tapes should not have obvious scratches.
4. whether the joint is flat. The cost-effective seamless splicing tape can not see the connector. The detection method depends on the touch. The more obvious the convex and concave feel, the worse the quality. The seam tape mainly depends on the processing technology of the connector. Only when the pressure is firm can it be considered as clearance. Gently fold the connector to see if it is warped. The adhesive tape can be disconnected from the connector even if it is slightly warped
