The principle of mechanical repair adhesive
« on: »
Adhesive has a special function and practical value,road leveling equipment motor grader for sale  in the construction machinery repair is widely used. The world is suitable for different uses of more than 10,000 kinds of adhesives, the choice of adhesive, according to the following four indicators.
 (1) resistance to media performance. Air, water, oil, acid, etc. collectively referred to as a variety of adhesives, most of the best anti-air media properties,fixing potholes in asphalt driveway the adhesive in the air the highest bonding strength. And in different properties of gas or annoying medium in the adhesive force is different, and even the work process of the angle of the individual is mainly air, water, oil and acid. When using adhesives, you should select the adhesive that uses the media.
 (2) Adhesive strength, per 1cm2 of the bonding surface, in the normal temperature and air medium in the destructive force known as the bonding strength,track shoes for asphalt paver  said MPa. Adhesive strength and sub-tensile strength, shear strength, torsional shear strength and stripping strong length, respectively, refers to the bonding force in the direction of the different stress strength. Select the adhesive, should be based on the location of mechanical parts and the feelings of misunderstanding to choose the appropriate strength of glue.
(3) temperature resistance, that is fully cured after the adhesive layer can withstand the temperature range, such as a temperature -60oC-120oC,chinese famous large asphalt paver  that is, the stick and can be in the range of -60oC to 120oC, beyond this limit, bonding The force dropped significantly. Engineering machinery in the air-cooled engine, the body temperature up to 130oC. Hydraulic oil temperature up to 120oC, select the adhesive must be in the kind of adhesive can withstand the temperature range.
