Product Description and Application 產品描述和用途
Irradiation cross-linkable flame-retardant automotive cable compounds which are produced with mixing, plasticizing and pelletizing process, regards polyolefin resin as the basic raw material, adds flame-retardant, antioxidant and sensabilizer. The highest working temperature are respectively 125℃and 150℃. The cables with it can meet ISO 6722 and DIN 72551 Standards. These products are suitable for the extruding insulation layers of 0.35 square meters and above of automotive cables.
輻照交聯阻燃汽車線料以聚烯烴樹脂為主要原料,加入阻燃劑,抗氧劑,助交聯劑,經混煉、塑化、造粒而得,最高工作溫度分別為125℃和150℃。制成電線后可以滿足ISO6722,DIN 72551標準,適用于0.35以上平方汽車線擠出絕緣層。
 
 
Processing Indicator加工工藝
General PVC or PE extruder is possible for the production of it. Recommend screw extruder with L/D≥25. It is better to put one 80 mesh filter on the position of screen while extruding. Temperatrue range changes according to different conditions of extruding equipment. Below temperature is just for boot debugging.
本產品可采用普通PVC或PE擠出機進行生產,建議螺桿長徑比L/D≥25,擠出過程中可在網板放置一層80目濾網。下列各溫度可作為開機調試的參考:

Conductor preheated to 110 ℃, and warm bath temperature about 40~60℃
導體預熱至110℃,溫水槽溫度40~60℃左右。
 
Irradiation Process輻照工藝
Irradiation dose of irradiation cross-linkable polyolefin automotive cables compound should be given according to thermal strength requirements (note: different accelerators with the same irradiation dose will cause different thermal strength values). The thermal strength should be controlled between 20%-40%. Generally speaking, the more bigger conductor, the larger irradiation dose amount.
輻照交聯型聚烯烴汽車線的輻照劑量應根據應以熱延伸達到要求為準(不同單位加速器按同一輻照劑量,其熱延伸值不一樣),本產品熱延伸需控制在20%~40%范圍內,導體越大,輻照劑量應適當的提高。
Attentions 注意事項:
1)The compound should be dried before using if the package is broken. Once package is open, recommend to run out within 12 hours.
原料破包需烘干后才能使用,材料一經開封,建議12小時之內用完。
2)Please ensure the screw, barrel , hopper are thoroughly cleaned before operation. Avoid bringing impurities while processing.
加工前確保螺桿、機筒、加料斗徹底清理干凈,加工過程中嚴禁帶入雜質。
3)If you need a faster extrusion. Please accelerate screw speed gradually to avoid inadequate plasticizing which may cause rough surface of the cables.
如果要快速擠出時,請慢慢逐漸加快螺桿轉速,以免塑化不良,電纜表面毛糙。
