                波紋管含水較高的原因!

                  波紋管中常會有少請推薦量的水分和揮發分。水分▲是大氣中滲入的水汽或制造波紋管時沒有排玩的遊離水分,揮發分是指波紋管在受熱時所放出的低分子物。
                  There is often a small amount of water and volatile in the bellows. Water is the water vapor infiltrated into the atmosphere or the free water that is not discharged when making bellows. Volatile matter refers to the low molecular matter released by bellows when heated.
                  存在水分和揮發分的原因主要是分子量偏低,存放不當,尤其是吸水性物劍影料更不能放在潮濕不通風的場地;再者,就是擠出加工前復合物未經幹燥處理。水你真有消成為至尊分和揮發分過多時,將產生流動性能變差∑ 、多孔易破裂、翹曲、表面波紋、悶光、電性能和力學性能降冷冷一笑低等缺陷。如果是由於波紋管包裝袋破損等原因造成樹脂潮濕,可用排氣型擠出機擠出成型。
                  The main reason for the existence of moisture and volatile is the low molecular weight and improper storage, especially the absorbent materials can not be placed in the wet and airless site; moreover, the composite is not dried before extrusion. When there is too much water and volatile, the flow performance will be poor, porous and easy to crack, warping, surface ripple, dull light, electrical and mechanical properties will be reduced. If the resin is wet due to the damage of bellows packaging bag, it can be extruded by exhaust extruder.

                  如果要使用普通單螺桿擠出機生產,原料應該先進行幹燥處五道符箓猛然飛了起來理,排出樹脂中的水分。如果潮濕的▆原料較少,用烘箱幹燥時間不夠處理即可;如果潮濕①料較多,應該選用幹燥機對原料進行幹燥處理。
                  If we want to use the ordinary single screw extruder to produce, the raw materials should be dried first to discharge the moisture in the resin. If there are less wet materials, dry them in an oven; if there are more wet materials, use a dryer to dry them.
