Brief introduction of nylon brush roller; sanding brush roller is abbreviated as sanding roller. It is configured in the sanding machine to soften the fabric or metal surface. The treated fabric surface has short and even fluff, and the hand feels fine and soft, and it is not easy to produce sand skin. Straight streaks common in hair. Nowadays, there are roughly the following methods for making brush rollers: 1. Direct hair transplanting This is the oldest method, which is to plant abrasive filaments directly on the grinding roller. Although the strength can be very high, the cost of hair transplanting is high, and Partial replacement is not possible, which is an initial reluctant choice. 2. Winding type This is a method of planting wool introduced from abroad. The abrasive wire is made into a metal strip that can be wound, and then wound on a sanding roller. It can be customized according to the length of the sanding roller, but because the abrasive wire is stuck on the metal strip, it will cause the phenomenon of wire drawing (abrasive wire is drawn out), the strength is not high, and only the two ends are fixed after winding, so it is difficult in the middle Do it tightly, if one end is loose, an accident will occur. 3. Although the production process of nylon sleeves is simple, it is also the one with the most problems. The thermal expansion and contraction of nylon will cause the nylon to grow, so that the nylon at the two ends of the roller body will grow out of a sanding roller to withstand the machine; use horse-riding nails for planting The bristles have low strength and are easy to shed hair; the thermal expansion and contraction of nylon will also cause the nylon sleeve to swell and crack and make the entire sanding roller scrap; the strength of nylon is not high, and the planting density cannot be increased. Although many foreign manufacturers also make it, but The most exposed problems are. 4. Aluminum alloy brush roller-The new type of brush roller is the best brush roller. It is made of aluminum alloy barrels, and can be customized to any length of brush roller; the high-strength aluminum alloy substrate can maximize the density of hair transplantation. Moreover, the most cutting-edge hair planting technology is used, which does not shed hair, and will not crack and grow like nylon; the roller body can accurately check the dynamic balance.
