There are many types of waterproof rollers, and they can be divided into ceramic rollers, cast stone rollers, nylon rollers, steel rollers, pulse-formaldehyde resin rollers, PVC rollers, ultra-high molecular weight polyethylene rollers. Rollers, phenolic resin rollers, glass fiber reinforced plastic rollers, polyurethane rollers, rubber rollers, etc. Among these different rollers, the more significant ones are nylon rollers, steel rollers, and pulse resin rollers.
The waterproof roller is divided by diameter. The roller can be divided into: 108 diameter, 89 diameter, 159 diameter, 133 diameter and 194 diameter. The diameters of rollers with larger specific gravity are 108 diameter, 89 diameter, 159 diameter and 133 diameter. The diameter of the roller is directly related to the length of the roller. If the diameter of the roller is 89, the length of the roller is usually 180mm and the length can reach 1000mm. The diameter of the roller is 108 and the length is 240mm. It is 1200mm; the diameter of the idler is 133, so its length is 375mm, the length is 1600mm, and the diameter of the idler is 159, then its length is 465mm, its length is 1800mm; its diameter is 194, then its length is short It is 600mm and the length is 2200mm.
