Pneumatic valve piece stick it remove the problems in maintenance

in pneumatic valve maintenance job, have met adhesive residue removal, stick to remove it. Adhesive is convenient, remove is difficult. Here are water, boiled, grilled method, chemical method and machining method to remove the glue, glue and clear. , water leaching water dissolves some dope, for this kind of adhesive bonding parts or clean up this kind of glue, can be soaked in water to remove or clear the parts, until the dope solution, stick it out. This kind of glue,, JQ, etc. , boiled, low molecular weight epoxy resin, such as,,,,, and other types of adhesives with ethylenediamine and PVC amine as fixative for cold curing adhesive, available in boiling water for about 10 minutes, depending on the size of workpiece, adjust water time, adhesive heated to soften, place the sticky it apart. , fire, use the heat such as stupid dipotassium anhydride curing agent, epoxy resin or other heat resistance performance in ℃ or so of the adhesive, with boiled method can't be remove, fire method can be used to soften its heating and hot cleaning residue or strike with a tool to pry open joints quickly. Note in this way can't heating temperature is too high, in order to avoid bonding parts heat annealing or burning. , chemical processing method using some adhesive acid-proof, alkali resistance, solvent resistance and other properties, the glue or to remove the parts or components, put in chemicals, to clear the residual gum or remove the adhesive joint. Such as inorganic limb roasted doesn't work, it is not alkali resistance, can lye to soak glue line, stick to it release, solvent adhesive, solvent resistance, such as polyvinyl chloride (PVC), poly (ethylene stupid is soluble in acetone. , mechanical processing method using the method such as grinding, disorderly, vehicles, drilling can clear, remove the joint.
