Qhov tseeb txoj hauv kev kom ncua lub neej kev pab cuam ntawm quartz raj
(1) Kev kho mob nruj.Yog hais tias ib qho me me ntawm alkali hlau xws li sodium thiab potassium thiab lawv cov tebchaw muaj paug rau ntawm lub khob quartz, lawv yuav dhau los ua crystal nuclei thaum siv kub thiab yuav sai sai crystallize, ua rau devitrification.Yog li ntawd, ua ntej siv, nco ntsoov soak lub quartz raj hauv 5-20% hydrofluoric acid rau 5-10 feeb, ces ntxuav nws nrog dej deionized, thiab thaum kawg so nws nrog degreasing gauze thiab qhuav nws.Lub qhov cub lub raj tom qab ziab yog nruj me ntsis txwv.Kov ncaj qha nrog koj txhais tes.
(2) Kub pretreatment.Thaum lub qhov cub tawg tshiab tau qhib los yog hloov nrog lub qhov cub tshiab, nws yuav tsum raug rau qhov kub thiab txias pretreatment.
(3) Thov xyuam xim tshwj xeeb rau 573″C.573 * C yog qhov hloov pauv siv lead ua ntawm quartz.Txawm hais tias nws yog cua sov los yog txias, nws yuav tsum dhau qhov ntsuas kub sai sai.
(5) Thaum lub raj quartz tsis ua haujlwm, qhov kub thiab txias yuav tsum tau qis, tab sis nws yuav tsum tsis txhob qis dua 800 ° C.
(6) Sim zam kom tsis txhob muaj cua sov thiab txias.Txawm hais tias quartz iav muaj qhov zoo thermal stability, opaque quartz iav los yog pob tshab quartz iav nrog lub thickness ntau dua 5 hli yuav ua rau tawg thaum kub hloov ntau dhau.Tshwj xeeb tshaj yog cov cuab yeej loj quartz iav nrog cov txheej txheem nyuaj feem ntau muaj kev ntxhov siab sab hauv, uas yooj yim dua yog tias nws tawg, ceev faj thaum siv nws.
(7) Txhawb nqa tag nrho thiab tig siv.Kub kub deformation ntawm quartz iav yog inevitable.Cov neeg siv yuav tsum tau them sai sai rau txo tus nqi ntawm deformation.Kev teeb tsa ntawm lub tsho tiv thaiv kev sib tsoo cua sov lub tes tsho tuaj yeem txo qhov kub thiab txias deformation ntawm quartz raj, thiab kev txhawb nqa tag nrho raws li qhov ntev ntawm lub raj quartz tuaj yeem txuas ntxiv kev pab cuam lub neej ntawm quartz raj los ntawm 2 ~ 3 zaug.Thaum lub quartz raj undergoes me ntsis dabtsi yog khoov deformation.Lub quartz raj tuaj yeem tig 180 *.Thaum lub quartz raj dhau elliptical deformation, lub pob zeb tuaj yeem ua tau
British tube tig 90 *, uas tuaj yeem txuas nws lub neej kev pabcuam.
