Yuav ua li cas kom paub meej cov av nplaum crucible kos duab fiberglass ntau lawm kab
Cov av nplaumfiberglasscov kab ntau lawm siv cov av nplaum crucible raws li cov hlau kos duab bushing rau kev ua haujlwm ntau lawm, uas yog qhov tseem ceeb sib txawv ntawm platinum crucible hlau kos duab thiab pas dej ua ke hlau kos duab kab ntau lawm. Tab sis rau cov neeg zoo tib yam uas tsis paub ntau txog kev lag luam fiberglass, cov av nplaum crucible hlau kos duab ntau lawm kab yog me ntsis "zoo ib yam" rau lub platinum-hloov crucible hlau kos duab ntau lawm kab, tshwj xeeb tshaj yog rau cov av nplaum crucible hlau kos duab ntau lawm kab nyob rau hauv ntau lawm. Nws yog qhov nyuaj kom paub qhov txawv ntawm platinum-rhodium alloy bushing hauv lub xeev.
Yog li yuav ua li cas kom paub qhov txawv ntawm cov av nplaum crucible hlau cov kab ntau lawm los ntawm platinum-hloov crucible hlau kos duab ntau lawm kab, tuaj yeem txheeb xyuas tau sai ntawm cov hauv qab no:
Ib qho yog saib cov qauv tsim thiab kev txhawb nqa hauv qab ntawm cov hlau kos duab bushing. Platinum-rhodium alloy bushings yog siv rau hauv platinum-hloov crucible hlau kos duab ntau lawm kab. Vim lawv lub neej ua haujlwm ntev, lawv tau nruab nrog bushing cib thiab cov chaw pabcuam xws li cov kav dej txias yog ntsia rau hauv qab ntawm bushings. Cov av nplaum crucible bushing siv nyob rau hauv cov av nplaum crucible hlau kos duab ntau lawm kab feem ntau muaj kev pab cuam lub neej txog ib hnub thiab yuav tsum tau hloov ntau zaus. Yog li ntawd, cov av nplaum crucible bushing yog ib qho yooj yim rau nruab, thiab tsis muaj qhov chaw pabcuam xws li cov kav dej txias rau hauv qab ntawm bushing.
Qhov thib ob yog saib cov qauv ntawm lub qhov cub tawg. Cov hlau kos duab rauv ntawm platinum hloov crucible hlau kos duab ntau lawm kab yog feem ntau ua nrog cov ntaub ntawv refractory, thiab nws cov duab zoo ib yam li lub voos xwmfab. Thaum lub sij hawm tsim khoom, iav pob raw khoom yog ntxiv rau lub melting rauv rau melting thiab homogenizing hlau daim duab. Lub melting rauv ntawm av nplaum crucible hlau kos duab ntau lawm kab yog kuj yooj yim. Feem ntau, refractory bricks los yog av nplaum cib yog piled los ua ib tug melting pas dej ua ke. Sab saum toj yog qhib los pab txhawb qhov sib ntxiv ntawm cov iav tawg thiab lwm yam khoom siv raw, thiab cov kua dej kub kub hauv qab yog pom.
Qhov thib peb yog saib cov khoom siv raw khoom siv. Lub platinum hloov crucible hlau kos duab ntau lawm kab siv iav pob ua raw khoom. Cov av nplaum crucible hlau kos duab ntau lawm kab feem ntau siv khib nyiab cullet li raw khoom, thiab lub Hoobkas cheeb tsam yog feem ntau nruab nrog khib nyiab iav tu khoom. Tau kawg, tseem muaj cov av nplaum crucible ntau lawm kab nrog cov iav pob, tab sis yog tias cov khoom siv raw siv hauv cov kab ntau lawm yog cullet, nws yuav tsum yog cov av nplaum crucible hlau kos duab ntau lawm kab.
Kev tsim thiab siv cov av nplaum fiberglass yuav coj ntau yam kev nyab xeeb, kev tiv thaiv ib puag ncig, thiab teeb meem kev sib raug zoo. Txog rau qhov kawg no, peb yuav tsum tau txiav txim siab txiav txim siab thiab ua tiav theem rov qab tsim muaj peev xwm ntawm cov av nplaum crucible hlau kos duab, tso lub hauv paus ruaj khov rau kev txhim kho zoo ntawm kev lag luam kev hloov pauv.
