Iav tau siv dav hauv lub sijhawm niaj hnub no thiab ib txwm yog cov khoom lag luam nrog kev lag luam loj. Los ntawm kev siv cov kev kho mob tshwj xeeb, peb tuaj yeem siv tag nrho cov yam ntxwv ntawm cov iav, thiab tuaj yeem ua rau nws qhov tsis xws luag, tsis raug rau lub ntuj tsim ntawm iav. Piv txwv li, laminated iav tuaj yeem tsis tsuas yog insulated, tab sis kuj cov khib nyiab yuav tsis txaws thiab ua mob rau tib neeg, muaj kev nyab xeeb thiab txhim khu kev qha. Tom ntej no, peb yuav qhia txog cov txheej txheem ntawm cov iav iav uas feem ntau siv hauv chav kuaj, thiab piav qhia txog hom tshuaj iav iav.
Ua ntej, hom tshuaj iav iav
Burner yog lub iav ntsuas uas tuaj yeem siv los ua kom sov cov tshuaj lom neeg. Cov khoom siv feem ntau nruj. Nws yuav tsum tau ua los ntawm cov khoom siv tawv 95 lossis GG-17 siab silicon boron iav. Nws yog tus cwj pwm los ntawm nyias thiab niaj hnub, thiab nws yog resistant rau quenching thiab kub.
Burners feem ntau xa mus rau beakers, conical (daim duab peb sab) flasks, peb (ib zaug, ob, plaub) puag ncig hauv qab flasks, ca hauv qab flasks, xeem raj, condensers (spherical, serpentine, ncaj, cua, thiab lwm yam), distillation hau, Fractionation taub hau , fractionation kem, rectification kem.
Cov cuab yeej ntsuas yog cov khoom siv iav nrog cov nplais meej thiab siv los ntsuas qhov muaj peev xwm. Cov khoom siv tuaj yeem ua los ntawm 75 cov ntaub ntawv, thiab nws cov qauv ntsuas zoo yog ntsuas qhov tseeb thiab ntsuas qhov tseeb.
Kev ntsuas ntsuas feem ntau yog xa mus rau ntsuas cov thoob, ntsuas khob, burettes (acid, alkali), pipettes (los yog kawm tiav straws), volumetric flasks, thermometers, hydrometers, qab zib meters, hygrometers, thiab lwm yam.
Lub thawv yog ua los ntawm iav uas muaj tshuaj lom neeg. Feem ntau, cov khoom yog thicker. Hais lus nruj me ntsis, kev xaiv cov khoom yuav tsum tau ua raws li cov tshuaj sodium-base chemical iav frit. Txawm li cas los xij, feem ntau cov tuam ntxhab tam sim no siv iav zoo tib yam. Cov yam ntxwv yog tias phab ntsa yog tuab. Lub thawv feem ntau yog hais txog ntau lub qhov ncauj qhov ncauj fwj, rhawv zeb, lub qhov ncauj hauv qab fwj, tso lub raj mis thiab ntau lub khob iav.
Tsis tas li ntawd, muaj ntau yam funnels (spherical, pear, drip, daim duab peb sab, thiab lwm yam), petri tais diav, tshuab ziab khaub ncaws, tshuab ziab khaub ncaws, tshuab ziab khaub ncaws, roj fwj, hnyav fwj (kho), mortars, iav raj, xuab zeb Core lim, thiab lwm yam. .
Kuj tseem muaj qee qhov me me ntawm cov iav kho qhov muag thiab cov khoom siv quartz iav xws li colorimeter, colorimetric raj, magnifying lens, microscope head.
Qhov tshwj xeeb ntawm cov cuab yeej iav feem ntau yog raws li ntim thiab ntev. Tib hom twj paj nruag yog nyias los ntawm me me mus rau loj. Txawm li cas los xij, vim yog qib kev siv hauv chav kuaj, qhov ntim ntawm 1ml thiab 10000ml, thiab qhov ntev yog feem ntau ntawm 5cm thiab 10000cm. Kev faib cov specifications thiab cov qauv siv lub hauv paus ntsiab lus ntawm halving.
Thib ob, cov txheej txheem tsim cov iav iav feem ntau siv hauv chav kuaj
1 raw khoom pre-processing. Cov khoom siv loj (quartz xuab zeb, dej qab zib tshauv, limestone, feldspar, thiab lwm yam) yog pulverized kom qhuav cov ntaub ntub dej, thiab cov khoom siv hlau uas muaj hlau yog raug tshem tawm cov hlau los xyuas kom zoo ntawm cov iav.
2 batch npaj.
3 yaj. Cov khoom siv iav batch yog rhuab ntawm qhov kub siab (1550 ~ 1600 degrees) nyob rau hauv lub pas dej ua ke los yog lub pas dej rauv los tsim ib lub khob kua uas yog ib yam, tsis muaj npuas thiab ua tau raws li qhov yuav tsum tau molding.
4 ua mold. Cov iav ua kua yog muab tso rau hauv pwm los tsim cov khoom iav ntawm qhov xav tau, xws li lub phaj tiaj tus, ntau yam khoom siv, thiab lwm yam.
5 kev kho cua sov. Los ntawm cov txheej txheem ntawm annealing, quenching, thiab lwm yam, kev ntxhov siab, theem kev sib cais los yog crystallization hauv cov iav raug tshem tawm los yog tsim, thiab cov txheej txheem ntawm lub khob hloov.
