長效型防靜電EVA泡棉
長效型防靜電EVA泡棉產品
緩沖抗震，靜電瞬間釋放，性能持久穩定
工藝簡介：
該產品為半開孔性海棉，系在雙分組EVA海綿的成型后，采用特殊工藝浸漬導電涂料，從而使其具備導電性能。其工藝流程可分為：
1、 聚醚型EVA海綿發泡生產；按工藝要求控制泡孔和密度；
2、 將前述海綿爆破除膜，使其成為開孔性海綿；
3、 將前述開孔性海綿浸漬到點涂料，干燥。
產品規則：
1、常規尺寸：
2.0m*1.0m*50mm\2.0m*1.0m*30mm\2.0m*1.0m*10mm\2.0m*0.5m*50mm\2.0m*0.5m*30mm\2.0m*0.5m*10mm
2、其他厚度如：15mm、20mm、25mm等需定制，交貨周期為20天。
Brief instruction of technique:
It is semi-instruction sponge, also the EVA sponge has mold, it uses special technique infuse conductive dope, and then can have conductive capability.
The technique procedure:
1. made the EVA sponge sparkle, the bore and density can be controlled as request.
2. blow up the bore and make it uncork sponge.
3. infuse and dryness.
Product dimension:
1. common dimension : 2.0m*1.0m*50mm\2.0m*1.0m*30mm\2.0m*1.0m*10mm\2.0m*0.5m*50mm\2.0m*0.5m*30mm\2.0m*0.5m*10mm
2. others like thickness of 15mm,20mm,25mm and etc, the delivery day is 20 days.
