3.3 Girazi reborosilicate rakakwirira kusvika panguva ino ndiro rakanyanya kunaka pasi rose rinogona kushandiswa kugadzira midziyo yemakemikari inouraya utachiona, pombi inokwana uye chiridzwa chegirazi chinoshandiswa mulabhu.3.3 high borosilicate girazi ipfupi kune borosilicate girazi ine kuwedzera coefficient pa (3.3±0.1) × 10-6/K-1, inotariswa sePyex girazi pasi rose.

Zvisungo zvepasi rose chiyero IS03587: girazi rekuisa uye girazi rekuisa rinoshandiswa kune makemikari zvinoshandiswa zvinofanirwa kutora 3.3 yakakwirira borosilicate girazi.

Girazi pombi uye zvivakwa muNantong Sanjing Kambani zvese zvinotora chiyero chepasi rose 3.3 borosilicate girazi rekugadzira nekugadzira.

Kupisa-kudzivisa kunaka

Girazi haina kunaka conductor uye brittle zvinhu, asi 3.3 borosilicate girazi rakasiyana kune ayo emakemikari zvikamu zvine 12.7% yeB2O3 iyo inovandudza zvakanyanya kugadzikana kwayo kwekupisa.

IS03587 tsanangudzo:

Pamusoro pegirazi reborosilicate rine dhayamita <Φ100mm, kupisa kwayo-kudzivisa kupisa hakuna kupfuura 120℃;

Kune yakakwira borosilicate girazi ine dhayamita> Φ100mm, tembiricha yayo yekudzivirira kupisa haina kukwira kupfuura 110 ℃.

Pasi pekumanikidzwa nguva dzose (20 ℃-100 ℃)

Heat transfer property

Avhareji yekupisa conduction: (20-100℃) λ = 1.2Wm-1K-1

Avhareji yekupisa chaiyo: Cp=0.98Jg-1K-1
