Tam sim no, hom thiab cov kev siv ntawm cov khoom siv iav tau dav thiab dav, thiab qee cov khoom iav tuaj yeem siv ncaj qha los ua cov tais diav.Txawm li cas los xij, vim qee cov neeg siv khoom tsis nkag siab txog cov khoom siv tshwj xeeb thiab kev siv cov khoom siv iav, lawv tau yuav thiab siv los ntawm kev yuam kev, thiab qee cov khoom iav tau tawg thiab ua rau tib neeg raug mob.
Tam sim no, cov iav iav uas cov neeg siv khoom feem ntau tuaj rau hauv lub neej hauv tsev feem ntau suav nrog peb pawg: iav zoo tib yam, iav tempered thiab iav kub-resistant.Cov iav tsis tuaj yeem siv rau hauv qhov chaw siv cov cua kub kub (qhov cub, microwave qhov cub);Tempered iav yog ib qho kev txhim kho cov khoom uas yog tempered los ntawm zoo tib yam dej qab zib txiv qaub iav los txhim kho cov neeg kho tshuab kev cuam tshuam, kev txhim kho ntawm nws thermal shock kuj yog txwv;Feem ntau ntawm cov iav kub-resistant yog nyob rau hauv borosilicate iav series, tab sis kuj suav nrog microcrystalline iav thiab lwm yam.Vim muaj cov tshuaj sib txawv, cov qauv kuj txawv ntawm cov iav zoo tib yam lossis cov iav tempered, borosilicate iav muaj cov thermal expansion coefficient me me, thiab muaj qhov kub thiab txias tsis kam.Nws yog qhov tsim nyog rau siv los ua lub thawv ntim khoom noj hauv chav ua noj thiab tuaj yeem tso ncaj qha rau hauv lub qhov cub microwave thiab qhov cub.
Cov khoom siv hauv chav ua noj kub-resistant iav feem ntau suav nrog cov khoom siv hluav taws xob kub-resistant, cov khoom siv hluav taws kub-tiv thaiv cov khoom siv tshiab thiab cov khoom siv ua noj, uas tuaj yeem muab faib ua qhov qhib hluav taws thiab hluav taws kub.Thaum tshav kub kub-resistant iav nrog ultra-low expansion coefficient, xws li microcrystalline iav, muaj lub thermal shock zog txog li 400 ° C.Cov saum toj no yog tsuas yog siv rau ncaj qha qhib nplaim taws cua sov, ua noj thiab withstanding ntse cua sov thiab txias.Cov khoom iav rau qhov hluav taws kub tsaus muaj lub zog thermal poob siab ntawm 120 saum toj no ℃, nws yog tsuas yog siv rau cua sov thiab ua noj ua haus lub sij hawm tsis ncaj qha qhib nplaim taws, xws li qhov cub thiab microwave ncu.Nws kuj yog ib qho khoom siv iav uas tiv taus cua sov hauv khw, xws li iav borosilicate.Txawm li cas los xij, tam sim no, daim ntawv lo ntawm cov khoom iav hauv kev ua lag luam tsis meej, thiab qee tus tswv lag luam kuj txhais tau tias yuav ua rau lub tswv yim tsis meej thiab nthuav cov haujlwm ntawm cov iav tempered zoo tib yam thiab txawm tias iav zoo tib yam.Yog li, Tuam Tshoj Consumers Association ceeb toom cov neeg siv khoom kom xyuam xim:
1. Cov iav tsis tuaj yeem siv rau hauv qhov chaw cua sov thiab ua noj ua haus, xws li tsis siv hauv qhov cub thiab microwave ncu, tempered iav uas tsis homogenized, xws li hauv qhov cub, kev siv microwave ncu yuav ua rau muaj kev pheej hmoo ntawm kev tawg thiab raug mob. (tam sim no "homogenized" tempered iav feem ntau yog siv rau kev lag luam, xws li iav tsheb, lub qhov rooj thiab qhov rais, rooj tog, thiab lwm yam).
2. Tam sim no, tsis muaj qhov hu ua tempered iav khoom los yog tempered heat-resistant iav khoom nyob rau hauv lub lag luam.Cov neeg siv khoom yuav tsum tsis txhob yuam kev thaum yuav khoom.
3. Thaum tshav kub kub-resistant iav khoom yuav tsum tau affixed nrog coj cov ntawv, qhia txog kev siv kub, siv ntau yam, thiab lwm yam. Tam sim no, borosilicate iav yog feem ntau ntawm cov iav kub-resistant, thaum microcrystalline iav muaj cua sov.
4. Kub-resistant iav khoom yog tau los ntawm annealing thiab txias, nrog zoo thermal stability, siab kub-resistant tam sim ntawd hloov kub, nyuaj ntau lawm thiab siab raug nqi.Yog tias cov neeg siv khoom pom cov khoom lag luam nrog cov iav nominal tshav kub tab sis tus nqi qis thaum yuav khoom, lawv yuav tsum xav txog lawv qhov tseeb.
