What is the difference between the thin and medium hair of a roller brush?
Roller brushes are very commonly used decoration tools and are used to roll paint.
The main differences between the fine hair and the medium hair of the roller brush are as follows:
1. First of all, from the appearance, the length of the hair is different, and the medium hair is a little longer than the fine hair.
2. Secondly, the effects of these two paintings are different. The paint surface after the fine-bristle roller brushing will be more uniform and smooth. The important thing is that there is no bumpiness; but the medium-bristle roller has a little bit after brushing. Concave and convex, not as good as fine hair.
For fine-bristle roller brushing, the flatness requirements for the wall surface will be higher, and the putty should be shaved better, if the wall is uneven, the phenomenon of rolling brush failure will occur. However, the medium-bristle roller brush does not have certain requirements for the wall surface, and it will be used more widely than the fine-bristle.
Both the Swedish roller brush holder and the American roller brush holder are used for the installation of the straight-through roller brush head. Compared with the American type, the rib structure is eliminated. The back end of the roller brush holder is used to limit the movement of the back cap. Both sides of the front cap are dotted. It is used to control the axial shaking amount of the drum, and the control method of radial shaking amount is the same as the American style. The Swedish brush holder presses against the inner wall of the brush head by the elasticity of the front cap.
