Cov iav me nyuam lub raj mis feem ntau yog tsim los ntawm borosilicate iav (tshwj xeeb siab -borosilicate iav) thiab dej qab zib- txiv qaub iav. Borosilicate iav-tshwj xeeb tshaj yog siab-borosilicate ntau yam-boasts ib coefficient ntawm thermal expansion, siab kub tsis kam, superior zog, siab hardness, siab transmittance, thiab tshwj xeeb tshuaj stability; yog li ntawd, nws muaj superior thermal kev ua tau zoo, lub cev durability, thiab kev nyab xeeb. Cov khoom lag luam iav thaum ntxov feem ntau yog ua los ntawm cov dej qab zib-cov kua txiv qaub iav, uas zoo li muaj qhov ntxhib tiav thiab nthuav tawm qhov tsis sib haum xeeb rau kev kub ntxhov tam sim ntawd. Yog li ntawd, cov neeg tsim khoom thiab cov neeg siv khoom tau raug qhia kom xaiv lub khob iav borosilicate thaum twg los tau.
Kev nyab xeeb ntawm iav me nyuam lub raj mis yuav tsum nruj me ntsis ua raws li cov qauv hauv tebchaws uas yuav tsum tau ua. Raws li lub teb chaws tus qauv GB 38995-2020, * Pub mis thiab mis rau cov me nyuam mos thiab cov me nyuam me* (tsim thaum lub Kaum Ib Hlis 1, 2021), lub khob lub cev ntawm tus me nyuam lub raj mis yuav tsum ua kom tau raws li cov kev xav tau ntxiv txog kev tiv thaiv thermal shock, dej tsis kam, qib kev ntxhov siab sab hauv, thiab lub zog ntawm lub zog. Tsis tas li ntawd, cov khoom no yuav tsum ua raws li lwm cov qauv, xws li GB 19778-2005 (* Tso cai txwv rau kev tso tawm cov hmoov lead, Cadmium, Arsenic, thiab Antimony los ntawm iav ntim ntim *) thiab GB 17762-1999 (* Kev nyab xeeb thiab huv si-Requirements for Glass. Muab nws cov tshuaj lom neeg ruaj khov, cov khoom siv iav yog qhov tsis muaj teeb meem ntawm cov organic tshuaj xws li Bisphenol A (BPA).
Lub raj mis me me muaj ntau qhov zoo sib xws: kev ruaj ntseg tshuaj lom neeg; tsis kam mus rau deformation thiab tso tawm cov khoom tsis zoo thaum lub sij hawm siab -kub kom tsis muaj menyuam (sawv kub tshaj 120 degree); thiab siab pob tshab, uas yooj yim saib xyuas cov kua mis ntim thiab mob. Lawv cov npoo sab hauv du tiv thaiv cov kua mis residue buildup, ua rau lawv yooj yim los ntxuav. Tsis tas li ntawd, iav fwj muaj cov thermal conductivity zoo heev, tso cai rau kev ntsuas kub kom raug thaum sov mis.
Hloov pauv, lub khob me nyuam lub raj mis muaj qee qhov tsis zoo: lawv hnyav heev, ua rau lawv tsis yooj yim nqa thiab nyuaj rau cov menyuam mos los tuav nws tus kheej. Ntxiv mus, iav yog qhov tsis yooj yim thiab raug cuam tshuam yog tias poob; Yog li ntawd, cov neeg siv yuav tsum tau siv ceev faj kom tsis txhob poob thaum siv. Rau kev tiv thaiv ntxiv-tshwj xeeb tshaj yog thaum mus ncig- nws raug nquahu kom muab lub raj mis nrog lub tes tsho tiv thaiv silicone los yog nqa mus rau hauv lub hnab ntim khoom uas muaj kev poob siab- absorbing tsim.
Thaum kev yuav khoom, cov neeg siv khoom yuav tsum tau txais cov khoom lag luam nrog daim ntawv pov thawj 3C siv tau los ntawm cov khw muag khoom tau tso cai thiab txheeb xyuas cov qauv siv tshwj xeeb (xws li GB 38995-2020) uas tau qhia rau ntawm daim ntawv lo khoom. Nws kuj raug pom zoo kom xaiv cov fwj uas muaj lub qhov ncauj dav dav, vim qhov no ua kom yooj yim ntxuav. Txawm hais tias cov me nyuam lub raj mis iav tau ruaj khov, nws raug nquahu kom tsis tu ncua tshuaj xyuas lub raj mis lub cev rau cov kab nrib pleb lossis cov cim ntawm hnav. Feem ntau, nws raug nquahu kom hloov lawv li ib xyoos ib zaug; Txawm li cas los xij, yog tias muaj cov kab nrib pleb tshwm, lawv yuav tsum tau hloov tam sim ntawd.
