制藥級軟管:制藥軟管，食品級硅膠管能被氫氟酸腐蝕么

　　制藥級軟管:制藥軟管，食品級硅膠管能被氫氟酸腐蝕么   來格雷特給大家講講吧

　　會的(de)(de)。含硅(gui)化學品無論無機(ji)的(de)(de)二氧化硅(gui)還(huan)是有機(ji)硅(gui)橡膠都不要接觸HF及(ji)含氟(fu)化合物溶液，它(ta)們對硅(gui)元(yuan)素(su)均具有侵蝕性(xing)，厚一點(dian)的(de)(de)硅(gui)膠管抵抗(kang)時間(jian)還(huan)長一點(dian)薄的(de)(de)容(rong)易透，請酌情參考(kao)。

　　制藥級(ji)軟管:解密食品(pin)級(ji)PU軟管和工業(ye)級(ji)PU軟管的區別

　　所謂“食品(pin)級”是對滿(man)足食品(pin)安(an)全(quan)國家標準的一種俗稱。實際(ji)上是不存(cun)在這么個(ge)級別的。

　　任何制(zhi)品，要冠以“食品級”，除了本身的各種要求外，還必須(xu)額外滿足(zu)食品安全國(guo)家(jia)標(biao)準的要求。

　　對于塑(su)料樹脂類產品，要(yao)成為“食品級(ji)”必須滿足以(yi)下標(biao)準：

　　《食(shi)品(pin)安(an)全國家標準食(shi)品(pin)接觸用(yong)塑料樹脂》

　　《食品安全國家標準食品接觸用塑料(liao)材料(liao)及制(zhi)品》
