管式電爐裝配石英玻璃管實驗一定要注意管口是否退火燒口處理
新聞分類:  技術資訊    瀏覽:2493    日期:2021/05/16    
使用石英管一定要特別注意研究使用過程中有3種石英玻璃材質,1、透明石英玻璃管2、彩色石英玻璃管3、濾紫外石英玻璃管。石英管熱處理中耐腐蝕效果和耐高溫效果熱處理穩定性非常好,電絕緣性能凸出,所以用于半導體、電光源、冶金、建材、化學實驗、機械配備多種領域。石英玻璃管高透光和石英法蘭,操作石英管深加工大型設備,針對細管短管的石英玻璃珠進行切割操作,石英管退火燒口、封底圓弧封底石英產品加工制作生產。

 
  石英管缺點是容易破碎如果生產工藝不好也會出現氣泡線等物理破損現象,拿放時一定注意磕碰導致石英管的破損,切割管口平整度對使用有很大的影響,管口邊緣處理一定要處理好不能有凹凸不平的豁口現象,所以要退火燒口處理,使其邊緣成圓弧狀態不割手,光滑度高這樣在管式電爐熱處理過程中會更好的耐高溫不容易炸裂。耐熱性雖好但一定要注意石英管的膨脹系數以免發生爆裂意外?;A的日常維護清理清潔工作要保持好,這樣會增強石英玻璃管的使用壽命。

石英玻璃管的熱膨脹系數小,但是石英玻璃管溫度達到1090攝氏度左右時,將其放入常溫的水池也是可以的并不會使其炸裂的現象發生。石英管的電阻值經過測算是普通玻璃的近萬倍絕緣性能表現非常出色,石英管是一種比較的玻璃制品,而對于絕大多數玻璃物品來說都有一定的透明使用性能,石英管的性能還在于紫外線到紅外線的整個光譜波段也可以保持非常好的透光性能這就是它的魅力所在。
