Detailed Product Description: | The reason is difficult to stick PTFE, mainly the following reasons: First, low surface energy, the critical surface tension is generally only 31 to 34 dyne / cm. Due to the low surface energy, contact angle, adhesives can not be fully customized wet PTFE Teflon plate and pipe rods, which are not well adhered to the PTFE; second, the degree of crystallinity, good chemical stability, swelling and dissolution of PTFE difficulties better than a non-crystalline polymer, when the adhesive coated PTFE surface, difficult to place into a chain polymer molecular chain diffusion and entanglement each domain, can not form a strong adhesion; third, PTFE structure is highly symmetrical, also belong to the non-polar polymers. The PTFE surface of the adhesive is adsorbed by van der Waals forces (intermolecular forces) caused by van der Waals forces comprising orienting force, induced force and dispersion forces. For non-polar polymer surface, do not have to form an alignment force and the force induced conditions, but can only form a weak dispersion forces PTFE plate tetrafluoroethylene rods tetrafluoroethylene units, and thus the adhesion is poor performance. Polytetrafluoroethylene [PTFE tetrafluoride, F4] is one of the best corrosion resistant materials in the world today, so too "plastic" reputation. Teflon is a tetrafluoroethylene polymer tetrafluoroethylene membrane PTFE gasket price, the abbreviation of PTFE, trade name "Teflon." PTFE is widely used in a variety of anti-acid and organic solvents need a place, which itself is not toxic to people, but one of the raw materials used in the production process of ammonium perfluorooctanoate (PFOA) is considered likely to have carcinogenic effects. Long-term work at a temperature of + 250 ℃ to -180 ℃ under, in addition to the molten metal and liquid sodium fluoride, the ability of all other chemicals. Teflon plate processing | tetrafluoroethylene | Tianjin Three by Three Plastic Co., Ltd. of Tianjin. Three Plastic Co., Ltd. Tianjin (www.tjzsxszp.com) strong, credible, in Tianjin plastic plate (sheet, section), rods and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead the Tianjin three and you work into the brilliant, for a better future! |
