Qhov txawv ntawm Soda txiv qaub iav thiab siab Borosilicate iav
May 31, 2023
Soda-lime iav thiab siab borosilicate iav yog ob hom iav uas muaj qhov sib txawv ntawm lawv cov muaj pes tsawg leeg thiab cov khoom.
Soda-lime iav, tseem hu ua dej qab zib-lime-silica iav, yog hom iav siv ntau tshaj plaws hauv cov khoom siv niaj hnub xws li qhov rais, lub raj mis, thiab cov tais diav. Nws yog tsim los ntawm melting ib tug ua ke ntawm soda tshauv, limestone, thiab xuab zeb nyob rau hauv ib tug kub kub. Hom iav no tsis muaj qhov ruaj khov thiab lub zog ntawm lwm hom iav, tab sis nws yog pheej yig thiab yooj yim los tsim.
High borosilicate iav, ntawm qhov tod tes, yog ib hom iav tshwj xeeb uas paub txog nws qhov tshwj xeeb kub tsis kam thiab tshuaj lom neeg ruaj khov. Nws yog tsim los ntawm kev sib xyaw ua ke ntawm boron oxide, silica, thiab lwm yam minerals ntawm qhov kub siab tshaj li dej qab zib-lime iav. Qhov sib ntxiv ntawm boron oxide rau cov iav sib tov muab nws cov thermal expansion coefficient ntau dua, ua rau nws tiv taus thermal shock thiab kev puas tsuaj tshwm sim los ntawm qhov kub thiab txias.
Lwm qhov sib txawv ntawm cov iav dej qab zib thiab cov iav borosilicate siab suav nrog lawv qhov ntsuas qhov ntsuas thiab qhov ceev. High borosilicate iav muaj qhov siab dua qhov ntsuas siab dua li cov iav dej qab zib, uas txhais tau hais tias nws khoov lub teeb sib txawv thiab pom meej dua thiab ci dua. Nws kuj muaj qhov ntom ntom dua li cov iav dej qab zib, uas ua rau nws sib zog dua thiab tiv taus kev tawg.
Zuag qhia tag nrho, qhov sib txawv tseem ceeb ntawm cov iav dej qab zib thiab cov iav borosilicate siab yog lawv cov muaj pes tsawg leeg thiab cov khoom, nrog cov iav borosilicate siab yog hom iav tshwj xeeb thiab ruaj khov uas feem ntau siv hauv cov khoom siv hauv chav kuaj, cov khoom siv ua noj, thiab lwm yam kev ua haujlwm siab. .
