為此筆者認為固相混合使hdpe晶粒尺寸變小,結晶度增大,使得異相成核的晶粒增多,參與導電的炭黑粒子數量減少:熔混卻使炭黑粒子表面被覆一層絕緣膜:這都將導致材料的導電性明顯變差,同時兩種混合還會造成炭黑結構的破壞,皆使得材料的導電性明顯變差。Hebei jingniu is a high - tech enterprise that specialises in the development and production of rolling crystallised glass, on - line coated float glass, crystal nucleus material and jade crystallised stone
