BOBBIN
Material quality：FRP composite pipel
Operation temperature：-20°C~120°C
Technology：After winding and shaping on the mold, it is dried for 48 hours before demolding to form a wool ingredient; Dimensions required for vehicle manufacturing, grinding the outer surface; After dust removal, the surface is sprayed with an anti-static layer that meets the 8th power standard of 10; Air dry naturally.
式样一
该式样因卷绕设备带挡块型顶针较小,需在两端安装端盖(端盖材质:PE 强度高,受外力不易破损)该方案优点是FRP管壁厚可以做到10mm及以内,重量轻，方便拿取。
式样二
该式样因卷绕设备带挡块型顶针较大，两端不好安装端盖。通过增加管壁厚度一般不低于15mm(具体看卷重量、卷筒长度来计算确定)车制斜度增加其顶针和挡块的接触面，从而确保其稳定性。该式样重量较重，一般用于收宽幅收卷,重量1吨以上
式样三
该式样和式样二唯一区别就是缺少挡块(主要还是设备顶针决定的)其它都一样
