Tus qauv rau cov tshuaj iav fwj yog ib ceg tseem ceeb ntawm cov txheej txheem rau cov khoom ntim tshuaj.Vim lub fact tias cov tshuaj iav fwj yuav tsum tau kev sib cuag ncaj qha nrog cov tshuaj thiab ib co yuav tsum tau mus rau lub sij hawm cia ntawm cov tshuaj, qhov zoo ntawm cov tshuaj iav fwj ncaj qha cuam tshuam rau cov tshuaj zoo thiab muaj feem xyuam rau tus kheej noj qab haus huv thiab kev nyab xeeb.Yog li tus qauv rau cov iav fwj tshuaj muaj qhov tshwj xeeb thiab nruj, uas tuaj yeem ua tiav raws li hauv qab no:
Relatively systematic thiab kev nthuav dav, txhim khu kev xaiv ntawm cov qauv khoom thiab kov yeej cov lag luam ntawm cov qauv ntawm cov khoom
Lub hauv paus ntsiab lus ntawm kev teeb tsa cov qauv sib txawv rau tib yam khoom raws li cov ntaub ntawv sib txawv tau txiav txim siab los ntawm cov qauv tshiab tau nthuav dav heev ntawm cov qauv kev pab cuam, txhim kho kev siv tau thiab kev xaiv ntawm ntau yam tshuaj tshiab thiab cov tshuaj tshwj xeeb rau cov khoom siv iav sib txawv thiab cov khoom ua tau zoo, thiab hloov pauv. tus txheeb ze lag ntawm cov qauv khoom lag luam hauv kev tsim khoom.
Piv txwv li, ntawm 8 cov tshuaj iav lub raj mis cov khoom siv los ntawm tus qauv tshiab, txhua yam khoom tau muab faib ua 3 pawg raws li cov khoom siv thiab kev ua haujlwm.Thawj qeb yog borosilicate iav, qeb thib ob yog iav borosilicate tsawg, thiab qeb thib peb yog sodium calcium iav.Txawm hais tias qee yam khoom lag luam nrog qee yam khoom siv tseem tsis tau tsim, cov qauv rau cov khoom lag luam no tau qhia, daws qhov teeb meem ntawm kev lag luam hauv kev teeb tsa cov qauv tom qab cov khoom feem ntau tsim.Ntau hom tshuaj uas muaj qib sib txawv, kev ua tau zoo, kev siv, thiab ntau npaum li cas cov ntaub ntawv muaj qhov hloov tau yooj yim dua thiab xaiv qhov loj dua rau cov khoom thiab cov qauv ua los ntawm cov khoom sib txawv.
Daim ntawv thov ntawm cov tshuaj iav raj mis qauv
Cov txheej txheem txheej txheem ntawm ntsug thiab kab rov tav interweaving ntawm ntau yam khoom thiab cov ntaub ntawv muab lub hauv paus txaus thiab tej yam kev mob rau kev xaiv ntawm scientific, tsim nyog, thiab haum iav ntim rau ntau yam tshuaj.Kev xaiv thiab siv cov tshuaj iav fwj rau ntau hom tshuaj uas muaj ntau hom tshuaj, cov khoom, thiab qib yuav tsum ua raws li cov hauv qab no:
tshuaj stability
Cov ntsiab cai ntawm kev ruaj ntseg tshuaj zoo thiab tsim nyog
Cov thawv iav siv los tuav ntau hom tshuaj yuav tsum muaj kev sib raug zoo nrog cov tshuaj, uas yog, kom ntseeg tau tias cov khoom siv tshuaj ntawm cov iav ntim tsis ruaj khov thaum lub sijhawm tsim khoom, khaws cia, thiab siv tshuaj, thiab qee yam khoom ntawm lawv tau raug tshuaj lom neeg. cov tshuaj tiv thaiv uas yuav ua rau kev hloov tshuaj los yog ua tsis tiav.Piv txwv li, cov tshuaj siv high-end xws li kev npaj ntshav thiab tshuaj tiv thaiv yuav tsum xaiv cov iav ntim uas ua los ntawm borosilicate iav.Ntau hom kev txhaj tshuaj muaj zog acid thiab alkali dej formulations, tshwj xeeb tshaj yog muaj zog alkali dej txhaj tshuaj formulations, yuav tsum tau xaiv iav ntim los ntawm borosilicate iav.Kev siv dav siv qis borosilicate iav ampoules hauv Suav teb rau kev npaj cov tshuaj txhaj dej tsis haum, thiab cov khoom siv iav no yuav tsum tau maj mam hloov mus rau 5 0 iav cov ntaub ntawv hloov mus sai sai nrog cov qauv thoob ntiaj teb, xyuas kom meej tias cov tshuaj nws muaj tsis tev. tawm, ua turbid, los yog deteriorate thaum siv.
Kev siv cov iav borosilicate tsawg lossis nruab nrab sodium calcium iav tseem tuaj yeem ua tau raws li cov kev xav tau ntawm kev ruaj ntseg tshuaj rau kev txhaj tshuaj, kev tswj qhov ncauj, thiab tshuaj infusion loj.Lub degree ntawm corrosion ntawm cov tshuaj nyob rau hauv iav yog feem ntau ntau dua nyob rau hauv cov kua ntau tshaj nyob rau hauv cov khib nyiab, thiab nyob rau hauv alkalinity tshaj acidity, tshwj xeeb tshaj yog nyob rau hauv muaj zog alkaline dej formulations, uas yuav tsum tau ntau dua chemical zog ntawm cov tshuaj iav fwj.
Resistance rau thermal shock
Zoo thiab haum rau qhov kub thiab txias hloov tam sim ntawd
Cov tshuaj sib txawv ntawm cov tshuaj yuav tsum tau kub kom qhuav, tshuaj tua kab mob thiab ua kom tsis muaj menyuam, lossis cov txheej txheem qis-kub khov-drying hauv kev tsim khoom, uas yuav tsum tau ntim cov iav kom muaj qhov zoo thiab tsim nyog rau qhov kub thiab txias tsis muaj tawg.Qhov kev tiv thaiv ntawm iav rau qhov kub thiab txias yog feem ntau cuam tshuam nrog nws coefficient ntawm thermal expansion.Qhov qis dua qhov coefficient ntawm thermal expansion, lub zog nws muaj peev xwm tiv taus qhov kub thiab txias.Piv txwv li, ntau hom tshuaj tiv thaiv qib siab, biologics, thiab lyophilized formulations feem ntau yuav tsum xaiv 3 3 borosilicate iav los yog 5 Borosilicate iav.Tsawg borosilicate iav uas tsim nyob rau hauv ntau ntau nyob rau hauv Tuam Tshoj yog nquag mus tawg thiab lub raj mis bottoming thaum raug kub hloov pauv.Muaj kev txhim kho tseem ceeb hauv Suav teb 3. 3% borosilicate iav, uas yog tshwj xeeb tshaj yog haum rau khov-drying formulations vim nws tsis kam mus rau kub tam sim ntawd hloov yog zoo dua 5 Borosilicate iav.
