耐火金云母帶是以優(yōu)質(zhì)金云母紙為基材，以無堿玻璃纖維布或薄膜作為增強(qiáng)材料,經(jīng)耐高溫有機(jī)硅樹脂粘合,高溫恒速烘烤干燥后，經(jīng)專用切割機(jī)切割加工成卷材
The refractory gold mica belt is made of high quality gold mica paper as the base material and alkali free glass fiber cloth or film as the strengthening material. It is bonded with high temperature silicone resin, baked and dried at high temperature and constant speed, and then cut and processed into coil by special cutting machine
