Kev ua thiab tsim cov txheej txheem ntawm lub raj mis iav

Cov ntaub ntawv tseem ceeb rau kev ua cov iav fwj yog: quartz xuab zeb, dej qab zib tshauv, calcite, limestone. Cov txheej txheem ntawm cov iav fwj feem ntau yog muab faib ua cov khoom siv melting, sib sau, ntug hlawv, thiab quenching.

Cov khoom siv melting: Ntxiv cov ntaub ntawv tsim khoom rau hauv lub qhov cub kom kub melting. Qhov kub hauv qhov cub yog nyob ntawm cov khoom sib txawv, feem ntau nyob ib ncig ntawm 1200-1600 degrees, thiab cov roj yog cov roj hnyav. hluav taws xob thiab lwm yam.

Muaj ob hom rauv lauj kaub: crucible thiab pas dej ua ke kiln. Lub crucible tsuas muaj ib qho chaw nres nkoj, thiab cov chaw noj mov thiab tso tawm yog nyob rau hauv qhov chaw nres nkoj no. Lub pas dej ua ke tej zaum yuav muaj nyias qhov chaw pub noj thiab tso tawm. Lub qhov cub zoo li no tsuas muaj ib qho chaw nres nkoj feem ntau siv thaum hmo ntuj. Kev pub mis yog nqa tawm, thiab tom qab ntawd airtight. Cov khoom siv tshiab tshiab yuav tsum tau yaj rau 8 teev, yog li kev pub mis tsis tuaj yeem nqa tau txhua lub sijhawm, thiab nws feem ntau ntxiv tom qab cov khoom siv lawm. Yog li ntawd, feem ntau ib lub tog raj kheej ntawm cov khoom siv tau rau ib hnub, txog li 600-900 litres.

Moulding: Cov txheej txheem molding muaj xws li tshuab (tshuab tshuab, phau ntawv tshuab), nias, thiab centrifugal rotation.

Cov khoom cua tshuab yog tsim los ntawm huab cua siab, yog li nws muaj kev sib raug zoo nrog qhov loj ntawm huab cua siab. Yog tias huab cua siab dhau lawm, lub hauv qab yuav nyias thiab lub qhov ncauj yog tuab. Tab sis nws ploj lawm. Cov khoom siv tshuab tshuab muaj xws li lub raj mis thiab cov kaus poom.

Nias: Nws yog nias lub puab pwm rau hauv pwm txheej extrude iav frit. Qhov sib txawv ntawm ob lub pwm cuam tshuam rau lub thickness ntawm cov khoom, thiab cov pwm sab hauv yog tswj los ntawm huab cua siab, yog li huab cua ntau dhau tuaj yeem txo qhov sib txawv ntawm ob lub pwm thiab ua rau hauv qab ntawm cov khoom thinner: yog tias huab cua siab. me me heev, qhov opposite yog qhov tseeb. Feem ntau, lub khob ncaj yog nias, tab sis yog tias cov khoom siab dua thiab cov ntug yog nyias, nws feem ntau yog tshuab, thiab qhov thinnest ntawm cov khoom no yog nyob rau hauv nruab nrab, yog li qhov nruab nrab yog yooj yim tawg.

Kev sib hloov centrifugal, pwm yog ntsia rau ntawm lub cev muaj zog, thiab cov khoom pov tseg thiab tsim los ntawm qee qhov ceev ntawm pwm. Yog tias qhov hluav taws xob ceev me me dhau, nws yuav tsis tuaj yeem muab pov tseg, uas yuav ua rau cov khoom tsis tiav. Yog tias qhov ceev yog siab dhau, cov khoom yuav raug muab pov tseg los yog tag nrho cov khoom yuav raug pov mus rau sab sauv, kom lub sab sauv yog tuab thiab hauv qab yog nyias. Feem ntau, txoj kev no yog siv rau cov khoom coiled.

Hlawv ntug: Thaum lub khob iav tsuas yog tawm ntawm cov pwm, lub qhov ncauj dav dav tsis yog du, tab sis nws yuav tsum raug rho tawm ntawm qhov kub thiab siv hluav taws xob ntau dua.
