Yuav ua li cas yog nickel hlau melted?
Melting ntawm nickel hlau yog hais txog cov txheej txheem ntawm cua sov nickel hlau saum toj no nws melting point kom yaj nws mus rau hauv cov kua daim ntawv. Nickel yog cov khoom siv hlau nrog cov ntawv thov tseem ceeb thiab cov txheej txheem melting tseem ceeb heev. Txoj kev melting ntawm nickel hlau yuav tau piav qhia hauv qab no.
Ua ntej, kev npaj. Ua ntej nickel hlau melting, koj yuav tsum tau npaj cov khoom siv thiab cov khoom siv raw. Thawj yog los npaj cov nickel hlau thiab cov cuab yeej melting, xws li rauv, crucible, melting point meter thiab lwm yam. Qhov thib ob yog los npaj cov kua dej thiab cov pa tiv thaiv, flux tuaj yeem pab tshem tawm cov oxides ntawm cov nickel hlau, cov roj tiv thaiv tuaj yeem tiv thaiv cov nickel hlau los ntawm oxidation. Qhov kawg yog ua tib zoo saib xyuas kev nyab xeeb, thaum ua haujlwm, peb yuav tsum ua txoj haujlwm zoo ntawm kev tiv thaiv kom tsis txhob muaj xwm txheej.
Tom ntej no, kev ua haujlwm melting. Muab cov nickel xaim npaj rau hauv lub crucible, thiab tom qab ntawd raws li lub melting point ntawm nickel hlau, qhov kub yuav maj mam nce mus txog rau thaum lub nickel hlau yog melted tag nrho rau hauv lub xeev cov kua. Nyob rau hauv cov txheej txheem no, nws yog ib qho tsim nyog yuav tsum ua kom lub qhov cub kub kom ruaj khov thiab tswj cov melting ceev kom tsis txhob overheating los yog tsis zoo kub tswj, uas ua rau muaj kev hloov nyob rau hauv cov muaj pes tsawg leeg ntawm cov nickel hlau los yog oxidation.
Tom qab ntawd, tshem tawm impurities. Thaum cov hlau nickel melted rau hauv cov kua hauv lub xeev, nws tuaj yeem pab tshem tawm cov oxides thiab lwm yam impurities nyob rau saum npoo ntawm cov hlau nickel los ntawm kev ntxiv cov yaj. Lub flux yuav muaj tshuaj lom neeg cov tshuaj tiv thaiv nrog cov oxides, ua rau cov oxides yaj rau ntawm cov nickel hlau thiab ces muab tshem tawm ntawm lub crucible nrog rau cov kua nickel hlau. Cov txheej txheem no yuav tsum muaj kev tswj xyuas zoo ntawm kev xaiv thiab sib ntxiv ntawm cov yaj kom tsis txhob muaj qhov cuam tshuam ntawm cov yaj ntau dhau, nrog rau kev tswj xyuas lub sijhawm thiab qhov kub thiab txias kom ntseeg tau qhov zoo ntawm cov hlau nickel.
Thaum kawg, txias thiab kho. Thaum lub lag luam ntawm melting npib tsib xee hlau thiab tshem tawm impurities tiav, nws yog tsim nyog los cia cov nickel hlau txias rau chav tsev kub, thiab ces tsim cov khoom nickel. Lub sijhawm no, cov hlau nickel tuaj yeem ua tiav raws li qhov xav tau, xws li dov, kos duab thiab lwm yam. Nyob rau tib lub sijhawm, cov khoom siv melting kuj yuav tsum tau muab ntxuav thiab khaws cia rau kev siv tom ntej.
Zuag qhia tag nrho, nickel hlau melting yog txheej txheem nyuaj uas yuav tsum tau ua tib zoo saib xyuas cov txheej txheem melting thiab ua tib zoo saib xyuas kev nyab xeeb thiab kev tswj xyuas kom tau txais cov khoom zoo nickel hlau. Los ntawm kev tshawb fawb thiab kev siv thev naus laus zis, cov khoom siv nickel hlau tuaj yeem tsim kom tau raws li cov kev xav tau sib txawv, muab cov khoom siv hlau tseem ceeb rau kev txhim kho thiab kev siv ntau yam kev lag luam.
