Iglasi ye-borosilicate ephezulu, luhlobo lokunyuka kwamaxabiso aphantsi, ukumelana nobushushu obuphezulu, amandla aphezulu, ubunzima obuphezulu, ukuhanjiswa kokukhanya okuphezulu kunye ne-High Chemical ukuzinza kwezinto ezikhethekileyo zeglasi, xa kuthelekiswa neglasi eqhelekileyo, imiphumo engeyiyo inetyhefu, iipropati zayo zomatshini, ukuzinza kwe-thermal. , ukumelana namanzi, ukuxhathisa kwealkali, ukuxhathisa kwe-asidi kunye nezinye iipropati zanda kakhulu, ezinokuthi zisetyenziswe ngokubanzi kwishishini lemichiza, i-aerospace, umkhosi, iintsapho, izibhedlele kunye nezinye iindawo, zingenziwa zibe izibane, i-tableware, i-scaleplate, i-telescope, umngxuma wokuqwalasela. umatshini wokuhlamba, i-oven microwave tray, izifudumezi zamanzi elanga kunye nezinye iimveliso, zinexabiso elihle lokunyusa kunye neenzuzo zentlalo, olu hlobo lweglasi kwilizwe lethu lushishino lwezinto ezisisiseko lutshintsho olutsha.
I-coefficient yokwandiswa komgca weglasi ephezulu ye-borosilicate yi-3.3 x 0.1 × 10-6 / K.Luhlobo lweglasi kunye ne-sodium oxide (Na2O), i-boron oxide (B2O2) kunye ne-silicon dioxide (SIO2) njengamacandelo asisiseko.Umxholo we-borosilicate kwicandelo leglasi liphezulu, ngokulandelanayo: i-boron: 12.5 ~ 13.5%; i-silicon: 78 ~ 80%, ngoko olu hlobo lweglasi lubizwa ngokuba yiglasi ephezulu ye-borosilicate
Iglasi ephezulu ye-borosilicate yenziwe ngokusebenzisa ipropathi yokuqhuba iglasi kwiqondo lokushisa eliphezulu, ukunyibilikisa iglasi ngokufudumeza ngaphakathi kweglasi, kwaye icutshungulwe bubuchwepheshe bemveliso obuphambili.Isetyenziselwa i-oven microwave.,ifestile yokujonga umatshini wokuhlamba isilinda njl njl. iti yeti ekwaziyo ukumelana nobushushu kunye necup yeti.
Iimpawu zomzimba kunye neekhemikhali zeglasi ephezulu ye-borosilicate zezi zilandelayo:
Isilicon＞80%
Ubushushu bobunzima bungama-520℃
Ubushushu be-Anealing yi-560℃
Ubushushu obuthambileyo bungama-820℃
Ubushushu bokulungisa (104DPAS) yi-1220℃
I-coefficient yokwandisa i-Thermal (20-300 ° C) 3.3 × 10-6K-1, ngoko ke ukupholisa ngokukhawuleza kunye nokumelana nokushisa ngokukhawuleza kuphezulu.
Ukunyamezela ukushisa: 270 degrees
Ubuninzi (20℃)
Ixesha lokuposa: Aug-20-2020
