3. Siv cov duab uas xav tau
(1) iav raj molding: cov iav kua yog rub mus rau hauv lub raj los ntawm lub raj rub lub tshuab, uas tuaj yeem ua los ntawm kev kos duab ntsug lossis kab rov tav.
(2) iav pas nrig molding: Cov iav kua feem ntau yog ua rau hauv pas nrig los ntawm kev tuag-casting los yog rub txoj kev.
4. Anneal
Moulded iav raj / pas nrig yog annealed kom tshem tawm cov kev ntxhov siab sab hauv thiab txhim kho nws lub zog thiab ruaj khov.
III. Daim ntawv thov teb ntawm siab boron silicon iav raj / pas nrig
1. Kev tsim teeb pom kev zoo
Nws yog feem ntau siv los tsim cov khoom siv hluav taws xob kub-tiv taus, teeb, thiab lwm yam, xws li halogen teeb, hnub ci teeb, thiab lwm yam.
2. Kev lag luam tshuaj
Nws yog siv los ua cov tshuaj tiv thaiv cov thawv, cov kav dej, thiab lwm yam vim nws cov tshuaj tiv thaiv corrosion zoo dua.
3. Kev ntsuas
Tsim cov khoom iav rau cov ntsuas kub, ntsuas ntsuas siab thiab lwm yam cuab yeej.
4. Kev lag luam hnub ci zog
Nws yog dav siv nyob rau hauv lub collectors ntawm hnub ci dej rhaub.
5. Cov khoom siv hauv tsev
Xws li cov khob dej kub-resistant, teapots, thiab lwm yam.
IV. Qhov teeb meem kev lag luam tam sim no thiab kev loj hlob zoo ntawm siab boron silicon iav raj / pas nrig
1. Kev ua lag luam tam sim no
Tam sim no, kev lag luam thov rau high-boron silicon iav raj / pas nrig txuas ntxiv mus, tshwj xeeb tshaj yog nyob rau hauv kev lag luam ntawm lub zog tshiab, hluav taws xob thiab tshuaj lom neeg kev lag luam. Nyob rau tib lub sijhawm, kev sib tw ua lag luam tau nce zuj zus, thiab cov tuam txhab tsim khoom txuas ntxiv txhim kho cov khoom zoo thiab kev ua tau zoo kom tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv.
2. txoj kev loj hlob
(1) Kev tsim kho thev naus laus zis: txuas ntxiv txhim kho cov txheej txheem tsim khoom, txhim kho cov khoom zoo thiab kev ua tau zoo, thiab txo cov nqi tsim khoom.
(2) Daim ntawv thov nthuav dav: Nrog rau txoj kev loj hlob ntawm kev lag luam tawm tshiab, daim ntawv thov teb ntawm siab borosilicate iav raj / pas nrig yuav raug nthuav dav ntxiv, xws li daim ntawv thov hauv semiconductors, aerospace thiab lwm yam.
(3) Kev tiv thaiv ib puag ncig ntsuab: xyuam xim rau kev tiv thaiv ib puag ncig thiab kev tsim kho kom ruaj khov ntawm cov txheej txheem tsim khoom, thiab txhim kho ntau cov khoom siv hluav taws xob thiab cov khoom lag luam.
V. Cov qauv zoo thiab cov qauv kev sim siab borosilicate iav raj / pas nrig
1. Cov qauv zoo
Nws feem ntau suav nrog cov cim qhia ntawm qhov zoo nkauj (xws li qhov chaw tiaj tus, npuas, impurities, thiab lwm yam), qhov tseeb qhov tseeb, lub cev muaj zog (xws li kub tsis kam, tshuaj lom neeg ruaj khov, lub zog txhua yam, thiab lwm yam).
2. Txoj kev kuaj xyuas
(1) Kev kuaj pom qhov tshwm sim: tshawb xyuas qhov tsis xws luag los ntawm kev soj ntsuam qhov muag liab qab lossis nrog kev pab ntawm lub tshuab tsom iav thiab lwm yam cuab yeej.
(2) Kev ntsuas qhov loj me: Siv cov calipers, micrometers thiab lwm yam cuab yeej los ntsuas qhov tseeb.
(3) Kev ntsuas kub tsis kam: siv cov ntsuas kub kub thiab lwm yam khoom siv rau kev ntsuas kub.
(4) Kev ntsuas tshuaj lom neeg ruaj khov: tsau cov qauv hauv cov kua qaub thiab alkali tshuaj xyuas nws cov corrosion.
