Borosilicate iav tau tau txais cov xim rau nws lub purported reciority ntau dua iav ntim hauv cov tshuaj pleev ib ce thiab ntau lwm cov ntawv thov. Tab sis puas yog nws tiag tiag?
Hauv tsab xov xwm no, peb tshem tawm mus rau hauv cov Cheebtsam, Cov yam ntxwv, Cov txiaj ntsig ntau ntawm cov iav, thiab sib txawv hom borosilicate iav kom muab qhov tseeb ntawm cov teeb meem no.
Dab tsi yog borosilicate iav?
Lub borosilicate iav yog tsim los ntawm 2 lub ntsiab xyaw: silica thiab boron. Silica lub suab me me yog qhov siab heev (1730 ° C), kom ua cov khoom siv no tau ua tiav ntawm qhov kub thiab li txuag hluav taws xob, lwm cov khoom siv tau ntxiv. Tsis tas li, lwm cov stabilizers (alkaline oxides, alumina, thiab alkaline oxides) tau ntxiv rau ntxiv dag zog rau lub zog, uas muab nws zoo heev cov khoom.
Qhov muaj pes tsawg leeg ntawm borosilicate iav 70% silica (tseem ceeb ntawm cov calkaline (stabilizers) los ntawm lwm yam alkalas (stabilizers) los ntawm lwm albosilicature
yam Iav zoo heev cov tshuaj kuj: tsis muaj tshuaj lom neeg ruaj khov thiab lub zog nyob hauv ib puag ncig corrosive. Kev kub siab kuj: Zoo heev tiv taus rau cov cua sov thiab cov thermal gradients, thiab tsis muaj cua sov nthuav dav. Zoo heev txhua yam muaj zog: zoo heev hnav- thiab kos-resistant, uas txhim khu kev qha lub zog thiab muaj peev xwm tiv thaiv cov neeg kho tshuab thauj. Siab pob tshab: kom ntseeg tau zoo heev thiab distortion-dawb teeb tau sib kis tau ntau yam tsis tshua muaj kev kub ntxhov heev. Hom borosilicate iav
borosilicate iav los nyob rau hauv ntau hom nyob rau hauv ntau hom nyob ntawm ntau hom nyob ntawm cov ntsiab lus boron oxide, uas cuam tshuam rau nws cov khoom. Cov hom no muaj xws li:
cov borosilicate iav: hom no muaj feem pua qis dua ntawm cov oxide feem ntau, feem ntau yog kwv yees li ntawm 5% mus rau 10%. Nws muaj qhov nruab nrab thermal poob siab thiab feem ntau siv nyob rau hauv cov khoom hauv tsev xws li cookware thiab ntxuav. Nruab nrab borosilicate iav: nrog lub coron oxide cov ntsiab lus los ntawm 10%, nruab nrab borosilicate iav kuj muab piv rau qhov qis borosilicate variant. Nws pom cov ntawv thov hauv kev kuaj thiab chaw teeb tsa uas yuav tsum muaj lub zog ntev dua. High borosilicate iav: High borosilicate iav muaj feem pua siab ntawm cov neeg hauv qab oxide ntau tshaj plaws, feem ntau tau tshaj 13%. Qhov kev khav theeb no zoo tshaj qhov tsis txaus siab thiab siv cov tshuaj kom haum, ua kom haum rau cov ntawv thov thiab cov khoom siv iav thiab kev ua haujlwm siab optics. Xaus lus xaus
rau hauv xaus, Borosilicate iav muaj ob peb qhov zoo dua iav, suav nrog cov cua sov tshiab, nrog rau kev ua haujlwm ruaj khov. Thaum borosilicate iav yuav tuaj ntawm tus nqi ntau dua, nws qhov kev ua tau zoo dua thiab kev ncua sij hawm ua pov thawj kev nqis peev, tshwj xeeb hauv kev ntim kom haum.
