Kev Taw Qhia

3.3 High borosilicate iav yog heretofore cov khoom zoo tshaj plaws nyob rau hauv lub ntiaj teb no uas yuav siv tau los ua tshuaj antiseptic khoom, yeeb nkab haum thiab lab-siv iav ntsuas. 3.3 siab borosilicate iav luv luv rau borosilicate iav nrog expansion coefficient ntawm (3.3 ± 0.1) × 10-6 / K-1, nws yog hais raws li Pyex iav thoob ntiaj teb.

Cov kev cai ntawm thoob ntiaj teb tus qauv IS03587: iav haum thiab iav haum siv rau kev siv tshuaj lom neeg yuav tsum tau txais 3.3 siab borosilicate iav.

Cov kav dej iav thiab cov chaw hauv Nantong Sanjing Company txhua tus txais yuav cov qauv thoob ntiaj teb 3.3 borosilicate iav rau kev tsim khoom thiab kev tsim khoom.

Thaum tshav kub kub-tiv taus zoo

Cov iav yog cov khoom siv tsis zoo thiab cov khoom siv tawv tawv, tab sis 3.3 borosilicate iav txawv rau nws cov khoom siv tshuaj muaj 12.7% ntawm B2O3 uas txhim kho nws cov thermal stability.

IS03587 specifications:

Rau siab borosilicate iav nrog txoj kab uas hla < Φ100mm, nws kub-kub tsis kam yog tsis siab tshaj 120 ℃;

Rau siab borosilicate iav nrog txoj kab uas hla> Φ100mm, nws kub-kub tsis kam yog tsis siab tshaj 110 ℃.

Nyob rau hauv qhov siab tsis tu ncua (20 ℃ - 100 ℃)

Thaum tshav kub kub hloov khoom
