纸张压纹辊01
1、石
1, stone roller
石辊为优质天然花岗石或人造石组成。由于其表面共有无数微孔,使纸页易于从其表面脱开。天然花岗石抗弯强度差,不宜作下压辊,以免压断,也不宜过冷、过热或局部受热,否则会使辊面爆裂,表面不能接触强酸、强碱以免破坏表面光泽度。
The stone roller is made of high quality natural granite or artificial stone. Because of its numerous pores, the surface of the paper is easily removed from its surface. The bending strength of natural granite is poor, it should not be used as a lower pressure roller so as not to break down, it should not be overcooled, overheated or partially heated, otherwise the roll surface will burst, and the surface can not contact strong acid and strong alkali to prevent surface gloss.
石辊与轴的结合是用两个左右旋向不同的螺母锁紧,在花岗石体与轴之间用水泥填塞或粘上。每一个石辊都有一定运转方向,使用时必须检查制造厂规定的转动方向与实际运动方向是否相符。
The combination of the stone roller and the shaft is locked by two left and right rotating nuts, and cement is filled or glued between the granite body and the shaft. Each stone roller has a certain direction of operation. When used, it must check whether the direction of rotation specified by the manufacturer is consistent with the actual direction of movement.
2、铜辊

真空引纸辊、光泽辊等采用磷青铜制造。由于铜质辊面硬度低,不耐磨、钢度较差。因
