                矽烷交聯聚乙烯絕緣料

                Silane cross-linked polyethylene insulation material

                矽烷交聯聚乙烯絕緣料
                特點及用途
                l 一步法:設備帶著那群玄仙回去告訴冷光投入小,操作簡單,成本低,保質期達1年。產品被使用時溫度控制要求小唯嚴格,操作工藝要求高。
                l 二步法:設備五帝投入大,成本高,保質期達半年。產品被使用時溫度易直接籠罩在整個千仞星控制,開線速度』快,質量穩定性好(主要表現在電纜的外觀質量及熱收縮指標上)。
                l 用途:用作0.6~10Kv中、低壓電力電纜、架空人手實在是太多了電纜的絕緣層。
                 
                包好裝運輸及貯存
                包裝:鋁塑復合防潮包裝25公斤/袋(二步法料內含小袋包裝催化母料B);
                運輸:小心輕放,以防破包;
                貯存:產品吸潮性強,打開包裝後應立即使@ 用,不必進一旁行預幹燥;產品∴未用完,需密封,後續使用間隔時間不宜過長不知道是對是錯啊,否則會影響擠出外觀。
                 
                執行標準:JB/T10437-2004。
                 
                Silane cross-linked polyethylene insulation material
                Feature and Usage
                l One-step method: the equipment investment is less, the operation is simple, the cost is low, and the quality guarantee period is up to 1 year. Temperature control when the product is used. Strict requirements and high operating process requirements.
                l Two-step method: the equipment investment is large, the cost is high,  the quality guarantee period is up to  half a year. The temperature is easy to be controlled when the product is used, and setting-out speed is fast and the quality stability is good (mainly shown on the appearance quality and thermal shrinkage index of cable).
                l Purpose: used as the insulation layer of  0.6 ~ 10KV medium and low-voltage power cable and overhead cable

                Packaging, transportation and storage
                Packaging: aluminum-plastic composite dampproof package: 25kg/ bag (in two-step method, catalytic masterbatch B with small bag packing is contained inside the material ); 
                 
                Transportation: Handle with care to avoid breaking the bag;

                Storage: the moisture absorption property of product is strong, the product shall be used immediately after opening the packaging, and the pre-drying is not necessary; If the product is not used completely, it is required to be sealed, and the  time interval for subsequent use should not be too long; otherwise, the extrusion appearance will be affected.
