Description

一种AB无机纤维芯板加工方法
技术领域
本发明涉及保温板材技术领域，尤其涉及一种AB无机纤维芯板加工方法。
背景技术
通常建筑保温材料保温效果不明显，究其原因，就在于墙体的保温芯板结构设计不合理。目前生产真空绝热保温板的企业选用的芯材有二氧化硅粉，普通硅酸铝板，玻璃纤维棉，选用二氧化硅粉芯材的真空绝热保温板产品芯材不能定性一直处于游离状态，暂时定型就上墙存在很大的不稳定性，一旦漏气便会涨袋脱落裂缝；普通硅酸铝类芯材炸球含量高导热系数差，玻璃纤维棉芯材导热系数好但是没有经过定型，弹性大，制作成真空绝热保温板一旦漏气随即出现1厘米的涨袋，恢复到没有抽真空前的松软状态，二氧化硅粉和玻璃棉芯材做成的板材硬度低。
