【產(chǎn)品說明】
氮化硅保護(hù)管優(yōu)點(diǎn)有高于其他產(chǎn)品的抗折的強(qiáng)度和抗氧化性能。最高使用溫度達(dá)1800℃。另外除了其本身的結(jié)構(gòu)特性,產(chǎn)品還具有良好的耐磨性能和對(duì)金屬溶液的抗腐蝕的性能,所以產(chǎn)品可以直接與鋁鋅銅鎂溶液接觸,不粘鋁陶瓷保護(hù)管已成功用于溫度測量。擁有其他耐火材料所不具備的特性,如高溫抗折,有意的高負(fù)荷載重和耐磨等性能。
【產(chǎn)品特點(diǎn)】
1、 優(yōu)良的抗氧化性能
2、 良好的耐磨性
3、 優(yōu)異的抗腐蝕性
4、 高溫抗折
5、 優(yōu)異的高負(fù)荷載重
6、 不粘鋁液

[product description]
The silicon nitride protective tube has higher bending strength and oxidation resistance than other products. Maximum operating temperature of 1800. Also inaddit-ion to its own structure characteristics, the product also has good wear resistance and on the metal solution corrosion resistant performance, so the product can di-rectly with aluminum, zinc, copper and magnesium solu-tion contact, adhesion of aluminum ceramic protection tube has been successfully used for temperature meas-urement. Have other properties, such as high temperature resistance, high load capacity and wear resistance, etc..
[product features]
1, excellent antionxidant properties
2, good wear resistance
3, the purpose of corrosion resistance
4, high temperature resistance
5, excellent high load
6, non stick aluminum liquid
