Usually it is in the selection of pumping paper, the first thing to look at the outer packaging of the pumping paper, if the pumping paper is a professional manufacturer, the outer packaging marked out the production and manufacturing date preservation period and so on, it shows that the pumping paper belongs to the reliable pumping paper, we can try to buy, naturally, in the selection of pumping paper must also look at the raw materials of the pumping paper.
01 because the raw materials of the pumping paper is particularly complicated, and we can directly buy the original ecological pulp of the pumping paper when selecting the pumping paper, ultimately this pumping paper does not add other residues, the relative meticulousness, but pure wood paddle of the pumping paper may be waste recycling, in the process of use will have small black spots.
02 When selecting the pumping paper, also according to the way to feel the touch to efficient, pick a generally better pumping paper feel good texture. But we are applying not so good in the pumping paper feel up, the texture is harder, more loose, rubbing when there will be pain.
03 A good bit of pumping paper chemical fiber degree is very long, good flexibility, expansion force is relatively large, and has the elasticity, generally not easy to be pulled off. However, the poor pumping paper will generally have the opposite force, so we are in the selection of pumping paper, it is best not to pick that type of very easy to break the pumping paper.
04 The drawing paper in the use of the process should also closely observe the ignition condition, generally with the drawing paper to carry out a better burning drawing paper is light gray, but the quality is not very good drawing paper is white or black gray, in addition we can also look at the fineness of the drawing paper.
