Qhov sib txawv tseem ceeb ntawm Gooch crucible thiab sintered iav crucible yog tias Gooch crucibles tuaj yeem tiv taus qhov kub siab tshaj li sintered iav crucibles.
Gooch crucible thiab sintered iav crucible yog cov khoom siv pom peb tuaj yeem siv hauv chav kuaj rau cov txheej txheem tshuaj xyuas. Gooch crucible yog ib hom khoom siv pom uas tuaj yeem tiv taus qhov kub thiab txias. Sintered iav crucible yog ib hom khoom pom ua los ntawm Pyrex iav.
Gooch Crucible yog dab tsi?
Gooch crucible yog ib hom khoom pom peb tuaj yeem siv hauv chav kuaj. Cov cuab yeej no tau muaj npe tom qab Frank Austin Gooch. Peb tuaj yeem muab nws lub npe Gooch lim thiab. Gooch crucible muaj txiaj ntsig zoo rau kev sau cov dej nag ncaj qha rau hauv lub nkoj uas peb tuaj yeem cia cov nag lossis daus qhuav, ua kom nws cov tshauv thiab ntsuas qhov hnyav ntawm cov qauv ntsuas los ntawm kev ntsuas gravimetric.
Keeb kwm, cov cuab yeej no tau tsim los ua tus qauv platinum crucible hauv cov chaw sim, thiab nws muaj lub hauv paus perforated. Lub hauv paus perforated no yog qhov tseem ceeb hauv kev tso cov asbestos pulp los ntawm lim lev. Tom qab ntawd, lub crucible tau rhuab nyob rau hauv ib lub qhov cub nyob rau hauv thiaj li yuav cia lub pulp qhuav kom txog thaum nws tau ib tug tas li qhov hnyav uas peb yuav ntsuas. Lub crucible no tuaj yeem raug kub siab rau ziab cov lim, thiab peb tuaj yeem oxidize cov ntsiab lus hauv crucible los yog ua kom cov filtrate ua nws cov tshauv uas muaj qhov hnyav tsawg. Txawm li cas los xij, kev siv platinum yog kim; Yog li, cov khoom ntawm Gooch crucible tau hloov nrog cov plooj (porcelain) xyoo 1882.
Nyob rau hauv qee qhov crucibles, muaj asbestos ob txheej txheej uas cais lawv los ntawm cov phaj porcelain perforated. Tsis tas li ntawd, qee qhov Gooch crucibles muaj inorganic fibers xws li iav nyob rau hauv qhov chaw ntawm asbestos. Gooch crucibles ua los ntawm borosilicate iav thiab fritted iav puag kuj muaj niaj hnub no. Platinum Gooch crucibles kuj pab hauv cov ntawv thov tseem ceeb xws li tuav cov ntaub ntawv corrosive. Hauv cov ntawv thov no, peb tsis tuaj yeem siv cov plooj (porcelain). Txawm li cas los xij, Gooch crucible ua los ntawm cov plooj (porcelain) txaus rau ashing cov khoom ntawm qhov kub thiab txias, thiab cov crucibles ua los ntawm borosilicate yog txaus rau ziab cov khoom.
Sintered iav Crucible yog dab tsi
Sintered iav crucible yog ib hom khoom pom ua los ntawm Pyrex iav. Pyrex iav yog hom iav resistant zoo heev. Nws yog haum nrog sintered av iav, lim disc ntawm ib tug me me deb ntawm qhov qis kawg. Feem ntau, cov cuab yeej no muaj txiaj ntsig zoo hauv kev sau cov nag lossis daus uas yuav tsum tau ziab.
Ntxiv mus, cov iav crucibles no muaj ntau qib ntawm porosity thiaj li haum rau precipitates ntawm ntau qhov sib txawv. Muaj ob hom loj xws li G3 thiab G4; G3 muaj txiaj ntsig zoo rau feem ntau cov dej nag, qhov G4 tseem ceeb hauv kev lim ob peb hom precipitate. Cov hom crucible no tsis tuaj yeem tiv taus qhov kub siab tshaj 400 degrees Celsius.
Tsis tas li ntawd, peb tsis tuaj yeem siv lub iav sintered crucible ncaj qha rau ntawm nplaim taws. Yog li ntawd, cov precipitate nyob rau hauv lub sintered iav crucible yog qhuav ntawm kub xws li ntawm 110 mus rau 120 degrees Celsius nyob rau hauv ib tug hluav taws xob qhov cub.
Qhov txawv ntawm Gooch Crucible thiab Sintered iav Crucible yog dab tsi?
Gooch crucible thiab sintered iav crucible yog cov khoom siv pom uas peb tuaj yeem siv hauv chav kuaj rau cov txheej txheem tshuaj xyuas. Gooch crucible yog ua los ntawm cov plooj (porcelain), hos sintered iav crucible yog ua los ntawm Pyrex iav. Qhov sib txawv tseem ceeb ntawm Gooch crucible thiab sintered iav crucible yog Gooch crucibles tuaj yeem tiv taus kub heev thaum sintered iav crucibles tsis tuaj yeem tiv taus qhov kub siab tshaj 400 Celsius degrees.
Cov duab hauv qab no qhia qhov sib txawv ntawm Gooch crucible thiab sintered iav crucible hauv daim ntawv tabular.
Summary – Gooch Crucible vs Sintered Glass Crucible
Gooch crucible yog ib hom khoom pom uas peb tuaj yeem siv hauv chav kuaj. Sintered iav crucible yog ib hom khoom pom ua los ntawm Pyrex iav. Qhov sib txawv tseem ceeb ntawm Gooch crucible thiab sintered iav crucible yog tias Gooch crucibles tuaj yeem tiv taus qhov kub thiab txias thaum sintered iav crucibles tsis tuaj yeem tiv taus qhov kub siab tshaj 400 degrees Celsius.
