sandpaper in the process of applying

Consumers have had to use sandpaper to sand paper will look at the use of the process easy to attack defects into two categories: First, abrasive own quality not good, two is the use of defective, select sanding roll  Carbon absurd road or equipment problems caused problems. So for this kind of question how we should deal with it?
Some type surface when machining, bending or uneven workpiece, often very soft belt hope to use. When the belt is very brittle, easily make the results not satisfactory abrasive. Belt brittle reason, in addition to soft music is not good, then there are the weather is too boring. Treatment approach is to belt it before use, try not to open the package, to prevent excessive boring, a premise, then should be placed in 15-200C, relative mini flap disc  humidity 50-60% of the cases among the belt is less brittle.
The first task is this: the belt of Burkina surface slope on the steel plate, vertical reciprocating gentle rub, rub a soft finish bias will tend to use the same belt, another way to end up and down gentle rub, can be reached tender objectives. Of course, in the production of mechanical belt Roll soft song has been carried out, this approach only  as a abrasive paper sheet  temporary remedy.Large rear Disposal: emery cloth roll out from the boring room after after disposal to go through a series of talent into the conversion process. Large rear cover themselves after curing, storage, humidifiers, soft music and so on. Disposal Through these processes, the function and quality of abrasive ability to reach the intended purpose.
