Description
Technical field
The utility model relates to the technical field of paint spraying, is a kind of repairing pin for teflon coatings specifically.
Background technology
Teflon coating is the fluorine coating taking polytetrafluoroethylene (PTFE) as matrix resin, and English name is Teflon, is conventionally referred to as again Teflon, the rich dragon of iron, Teflon, teflon etc. (being all the transliteration of Teflon).Teflon coating is a kind of unique high-performance coating, combine heat resistance, chemical inertness and excellent insulation stability and low frictional properties, have the comprehensive advantage that other coating cannot contend with, the flexibility of its application makes it can be used for nearly all shape and big or small product.
Teflon is divided into PTFE, FEP, several fundamental types of PFA, ETFE: PTFE(polytetrafluoroethylene (PTFE)) non-viscous paint can be 260 DEG C of uses continuously, there is maximum operation (service) temperature 290-300 DEG C, extremely low coefficient of friction, good wearability and fabulous chemical stability.FEP(fluorinated ethylene propylene copolymer) non-viscous paint when baking melt-flow form nonporous film, there is remarkable chemical stability, fabulous sticky characteristic, maximum operation (service) temperature is 200 DEG C.PFA(crosses fluoroalkyl compound) non-viscous paint the same with FEP when baking melt-flow form nonporous film.The advantage of PFA is to have 260 DEG C of higher continuous serviceability temperatures, and the strong and unyielding degree that tool is stronger is particularly suitable for using antiseized under hot conditions and chemical resistance use field.ETFE is the copolymer of a kind of ethene and tetrafluoroethene, and this resin is the most tough and tensile fluoropolymer polymer, can form the coating that a layer height is durable, has remarkable chemical resistance, and can continuous operation at 150 DEG C.
After Teflon application, there is following characteristic: 1, viscosity not: nearly all material is not bonding with Teflon film.Very thin film also demonstrates well not adhesion property.2, heat resistance: Teflon film has good heat-resisting and low temperature tolerance characteristics.Short time can be high temperature resistant to 300 DEG C, generally between 240 DEG C ~ 260 DEG C, can use continuously, has significant heat endurance, and it can work and not embrittlement under cryogenic temperature, does not at high temperature melt.3, sliding: Teflon film has lower coefficient of friction.When load is slided, coefficient of friction changes, but numerical value is only between 0.05-0.15.4, moisture resistance: Teflon film without water stained on its surface and oil, when production operation, be also difficult for being stained with solution, as be stained with a small amount of dirt, simple wiping can be removed.Downtime is short, saves man-hour and can increase work efficiency.5, mar proof: under high capacity, there is good anti-wear performance.Under certain load, possesses wear-resistant and inadhesive two-fold advantage.6, corrosion resistance: Teflon is corroded by medicine hardly, can protect part to avoid suffering the chemical attack of any kind.That Teflon is widely used in is high temperature resistant, require to do the industry of viscosity.
The application of Teflon coating is divided into the dispersion coating coating process of wet type and the powder paint coating method of dry type conventionally.The coating process of dispersion coating is coating material to be evenly distributed in solvent form dispersion liquid (solid matter is mixed in liquid), and this mixture is by pressure-air atomization and be sprayed at surface of the work.The coating material using in powder paint coating method is ultrafine solid particle form, avoid using solvent, thereby the Divergent Phenomenon occurring while avoiding coating to adhere to is attached on workpiece micro mist shape coating granule, subsequently, the micro mist of coating melting in baker.
And there is unavoidably leak source in Teflon coating in coating process, in prior art, repair leak source and conventionally have following technical scheme: a kind of scheme is that powder is coated on glass plate by the mode of electrostatic spraying, coating after moulding is being separated with glass plate, and cut into strip and block, use the patch of above-mentioned strip and block to repair leak source, adopt the coating flatness after this scheme is repaired poor, and complex steps; Another kind of scheme is to use heat gun to concentrate heating to leak source position, when the coating of leak source is during in the hot state of height, use naked hand to dip powder and be coated in rapidly leak source, conventionally dipping and apply This move will repeat ten to 20 times, this method for repairing and mending can be controlled adhering to accurately of powder, coating protection after repairing is maintained an equal level whole, but workman's hand is easily burned in mending course, and puts on uncontrollable powder amount and the mending course of dipping in after the gloves of protective.
Summary of the invention
It is a kind of repairing pin for teflon coatings specifically that the technical problems to be solved in the utility model is to provide.
The technical scheme that the utility model is taked for the technical problem existing in solution known technology is:
The repairing pin of teflon coatings of the present utility model, comprise and form the shank of repairing pin main body, one end of shank forms sharp-pointed needle point, and the other end of shank is set to powder spoon.
The utility model can also adopt following technical measures:
Described powder spoon is semi-surrounding structure, forms in the inside of powder spoon wall the space that holds powder, and the opening of powder spoon is arranged near on the powder spoon wall of shank one side, and powder spoon wall inner side is cambered surface with outer surface.
The opening direction of described powder spoon and shank are acute angle between the direction of the place of needle point; Shank is crossing with the outside cambered surface of powder spoon wall to the extended line of powder spoon direction.
Shank, needle point and the powder spoon of described repairing pin are structure as a whole.
