What are the functions and maintenance methods of automotive adhesives?
The adhesive polymer material for soil, some will have to add a certain amount of solvent, to achieve curing rely on chemical reactions or physical effects, these binders in the storage process will occur slowly. Therefore, the adhesive has a certain storage period, and the storage conditions, such as temperature, humidity, ventilation and other related. In order to ensure that the adhesive in the prescribed period of performance basically unchanged, it is necessary to pay strict attention to the storage of adhesive method. For different kinds of adhesives, because of their different nature, the storage conditions are not the same.
The role of adhesives for automobiles is to repair the damaged parts of the car and to make permanent permanent adjustments in the repair of the car to fill the dent in the car body. Including car repair, car body structure, power system, operating system four kinds of rubber species.
Several commonly used adhesive storage notes are as follows;1. The epoxy resin adhesive should be stored in ventilated, dry, cool and room temperature environment for a period of six months to one year.2, phenolic resin adhesive should be installed in sealed containers, stored in a cool place far from the fire, for a period of six months to L years.3, polyisocyanate glue liquid should be packed in brown bottle, avoid light and low temperature storage, can't use metal container, can't use rubber and cork stopper. And to prevent water entering, otherwise it will polymerize modification; prepolymer polyurethane adhesive to avoid low-temperature storage, to prevent condensation, the first component can be stored for a period of 2 years, their components must pay attention to moisture, and avoid moisture or other active hydrogen containing substances in contact for a period of six months to 1 years.4, urea formaldehyde resin adhesive storage temperature should be as low as possible. If add 5% methanol Oh, improve storage stability.5, neoprene adhesive containers, sealing good. Room temperature storage, not too high temperature (>30 degrees Celsius) or too low (<5 degrees Celsius), away from the fire source. Storage period is 3 - June.6, a- cyanoacrylate adhesive should be in place of reservoir seal, low temperature, dry, cool place, a period of 1 years. A glass bottle holds longer than a plastic bottle.
