Isingeniso Sezobuchwepheshe
3.3 Ingilazi ephezulu ye-borosilicate iyimpahla ekahle kakhulu emhlabeni engasetshenziselwa ukwenza izinto ezisetshenziswa ngamakhemikhali ezibulala amagciwane, ukufaka amapayipi kanye nezisetshenziswa zengilazi ezisetshenziswa elebhu.Ingilazi engu-3.3 ephezulu ye-borosilicate imfushane kungilazi ye-borosilicate ene-coefficient yokwandisa ku-(3.3±0.1)×10-6/K-1, ibhekiswa njengengilazi ye-Pyex emhlabeni jikelele.
Imibandela yezinga lamazwe ngamazwe IS03587: ukufaka ingilazi nokufakwa kwengilazi okusetshenziselwa izinto zamakhemikhali kufanele kuthathe ingilazi engu-3.3 ephezulu ye-borosilicate.
Ipayipi lengilazi kanye nezinsiza eNantong Sanjing Company zonke zamukela ingilazi ye-borosilicate ejwayelekile yamazwe ngamazwe engu-3.3 yokukhiqiza nokukhiqiza.
Ikhwalithi yokumelana nokushisa
Ingilazi iwumqhubi ompofu kanye nezinto eziphukayo, kodwa ingilazi engu-3.3 ye-borosilicate ihlukile ngenxa yezingxenye zayo zamakhemikhali iqukethe u-12.7% we-B2O3 othuthukisa kakhulu ukuqina kwayo okushisayo.
Imifanekiso ye-IS03587
Ngengilazi ephezulu ye-borosilicate enobubanzi <Φ100mm, izinga lokushisa layo elimelana nokushisa alikho ngaphezu kuka-120℃;
Ngengilazi ephezulu ye-borosilicate enobubanzi > Φ100mm, izinga lokushisa layo elimelana nokushisa alikho ngaphezu kuka-110℃.
Ngaphansi kwengcindezi engaguquki (20℃-100℃)
Impahla yokudlulisa ukushisa
Isilinganiso sokwenziwa kokushisa: (20-100℃) λ = 1.2Wm-1K-1
Isilinganiso sokushisa okuthile: Cp=0.98Jg-1K-1
