3.3 Iglasi yeborosilicate ephezulu ngoku sesona sisixhobo sifanelekileyo ehlabathini esinokusetyenziswa ukwenza izixhobo zekhemikhali zokubulala iintsholongwane, ukufakela imibhobho kunye nesixhobo seglasi esisetyenziswa elebhu.I-3.3 iglasi ye-borosilicate ephezulu imfutshane kwiglasi ye-borosilicate ene-coefficient yokwandisa (3.3±0.1)×10-6 / K-1, ibhekiswa njengeglasi yePyex kumazwe ngamazwe.

Imimiselo yomgangatho wamazwe ngamazwe we-IS03587: ukufakwa kweglasi kunye nokufakwa kweglasi esetyenziselwa izinto zekhemikhali kufuneka kuthathe i-3.3 yeglasi ye-borosilicate ephezulu.

Umbhobho weglasi kunye nezibonelelo kwiNkampani yaseNantong Sanjing zonke zamkela umgangatho wamazwe ngamazwe we-3.3 yeglasi ye-borosilicate yokuvelisa kunye nokwenza.

Umgangatho wokumelana nobushushu

I-Glass i-conductor ehluphekileyo kunye ne-brittle material, kodwa i-3.3 yeglasi ye-borosilicate ihluke kumacandelo ayo ekhemikhali iqulethe i-12.7% ye-B2O3 ephucula kakhulu ukuzinza kwayo kwe-thermal.

IS03587 imilinganiselo:

Kwiglasi ephezulu ye-borosilicate enobubanzi <Φ100mm, ubushushu bayo bokumelana nobushushu abukho ngaphezu kwe-120℃;

Kwiglasi ephezulu ye-borosilicate enobubanzi> Φ100mm, ubushushu bayo bokumelana nobushushu abukho ngaphezu kwe-110℃.

Phantsi koxinzelelo rhoqo (20℃-100℃)

Ipropati yokutshintshwa kobushushu

Umyinge wokuqhuba ubushushu: (20-100℃）λ = 1.2Wm-1K-1

Umyinge wobushushu obuthile: Cp=0.98Jg-1K-1
