对于生产多年的PVC软管厂家来说,对软管的制造工艺比较熟悉,但大多数客户并不是很清楚。下面Orientflex软管厂家为大家分享PVC软管的制造工艺。
第 1 步:混合配料
PVC软管生产前,应将各种原料准确称量,按一定顺序放入混料机中。加料顺序为:PVC树脂、增塑剂、稳定剂、润滑剂。当温度达到100-110℃时,即可出料。
Step 2: Extrusion granulation
In this process, the temperature should be well controlled, and the temperature of the material should be controlled at a high point higher than the melting temperature of the material and lower than the extrusion molding temperature, that is, between 155 and 160 °C. The purpose of granulation is to achieve full mixing and initial plasticization. The temperature of each zone of the granulator is as follows, one zone is 80~90°C; the second zone is 130~140°C; the third zone is 140~150°C; the nose is 150~160°C.
Step 3: Extrude Tube Forming
挤出温度稍高。一般来说,管材的透明度与成型温度有关。在一定的温度范围内,高温透明性好,反之亦然。同时,拉拔速度和冷却速度都会影响管材的透明度。牵引速度稍高,冷却速度较快,管材透明度较好。牵引速度一般比挤压速度快10%~15%。PVC软管成型后,需要进行冷却。先在头模上喷冷水,然后进入水槽冷却成型。
