Usually in the selection of extraction paper, the first thing to look at the outer packaging of extraction paper, if extraction paper is a professional manufacturer, the outer packaging marked with production date, storage period and so on, it shows that extraction paper belongs to the reliable extraction paper, we can try to buy, nature in the selection of extraction paper must also look at the raw materials of extraction paper.
01 Because the raw materials of pumping paper are especially complicated, and we can directly buy the original ecological pulp of pumping paper when selecting pumping paper, after all, this pumping paper does not add other residue, relative meticulous, but the pure wood paddle pumping paper may be waste recycling, there will be small black spots in the process of use.
02 When choosing paper, we should also be efficient according to the way of touch, and choose a better paper to feel good. But we are not very good in the application of paper to touch up, the texture is hard, more loose, friction will have pain.
03 Better extraction paper chemical fiber is very long, flexibility is good, expansion tension is relatively large, and elastic, generally not easy to be pulled off. However, poor extraction paper will generally react, so when we choose extraction paper, it is best not to choose that kind of very easy to break extraction paper.
04 Pumping paper in the process of use should also closely observe the lighting condition, generally use pumping paper to carry out burning better pumping paper is light gray, but the quality is not very good pumping paper is white or black gray, in addition, you can also see the fineness of pumping paper.
