Hav nyob ntawd! Raws li tus neeg muag khoom ntawm Graphite Stoppers, Kuv feem ntau tau nug txog hluav taws xob tiv thaiv ntawm cov khoom me me no. Yog li, cia peb dhia dej mus rau hauv thiab tawg nws.
Ua ntej tshaj, Graphite Stoppers yog dab tsi? Zoo, lawv yog ib qho tseem ceeb hauv ib pawg ntawm cov ntawv thov kev lag luam, tshwj xeeb tshaj yog hauv cov hlau smelting. Lawv tau siv los tswj cov dej ntws ntawm cov hlau molten, ua kom cov txheej txheem du thiab meej. Tab sis thaum nws los txog rau hluav taws xob tiv thaiv, qhov ntawd yog tag nrho lwm qhov kev ua si.
Graphite, feem ntau, muaj qee qhov zoo nkauj zoo nkauj. Nws yog ib daim ntawv ntawm carbon, thiab nws cov qauv atomic muab nws cov yam ntxwv tshwj xeeb. Ib qho ntawm cov no yog nws muaj peev xwm tiv taus qhov kub thiab txias. Qhov tseeb, graphite tuaj yeem tswj qhov kub txog li 3000℃hauv qhov chaw tsis muaj zog. Qhov siab - kub tsis kam no yog ze rau nws cov hluav taws xob tiv thaiv.
Thaum peb tham txog hluav taws xob, peb feem ntau yog xa mus rau ionizing hluav taws xob, xws li gamma rays thiab neutrons. Cov hom hluav taws xob no tuaj yeem ua rau muaj kev puas tsuaj rau cov ntaub ntawv los ntawm knocking atoms tawm ntawm qhov chaw, tsim kev puas tsuaj rau cov qauv siv lead ua. Tab sis graphite muaj cov qauv ruaj khov uas tuaj yeem zam tau qhov ncaj ncees ntawm qhov kev tsim txom no.
Cov hluav taws xob tiv thaiv ntawm graphite los ntawm nws cov khoom muaj zog covalent bonds ntawm carbon atoms. Cov ntawv cog lus no nyuaj rau kev tawg, txawm tias nyob rau hauv lub siab ntawm - hluav taws xob hluav taws xob. Thaum hluav taws xob hits graphite stopper, lub zog yog absorbed thiab dissipated los ntawm tus txheej txheem hu ua inelastic scattering. Qhov no txhais tau hais tias es tsis txhob ua kev puas tsuaj mus tas li rau cov qauv graphite, lub zog tau nthuav tawm thiab tso tawm raws li cua sov.
Hauv kev lag luam chaw, hluav taws xob tsis kam ntawm Graphite Stoppers yog qhov tseem ceeb. Piv txwv li, nyob rau hauv nuclear fais fab nroj tsuag, qhov twg cov hluav taws xob theem siab heev, graphite Cheebtsam yog siv vim hais tias ntawm lawv muaj peev xwm tiv taus hluav taws xob tsis tau poob lawv cov qauv kev ncaj ncees. Ib yam li ntawd, nyob rau hauv cov txheej txheem hlau smelting uas koom nrog hluav taws xob - emitting qhov chaw, Graphite Stoppers tuaj yeem ua kom muaj kev nyab xeeb thiab ua haujlwm ntawm kev ua haujlwm.
Tam sim no, cia peb tham txog yuav ua li cas peb Graphite Stoppers raug tsim. Peb siv siab - cov ntaub ntawv zoo graphite uas tau ua tib zoo xaiv rau lawv cov hluav taws xob hluav taws xob - resistant zog. Peb cov txheej txheem tsim khoom suav nrog kev ua haujlwm zoo los xyuas kom meej tias txhua tus nres ua tau raws li cov qauv nruj tshaj plaws. Qhov kev mloog rau kev nthuav dav no txhais tau tias peb cov Graphite Stoppers tsis yog tsuas yog muaj hluav taws xob zoo heev tab sis kuj muaj lub neej ua haujlwm ntev.
Ntxiv nrog rau kev tiv thaiv hluav taws xob, peb Graphite Stoppers kuj muaj lwm yam txiaj ntsig. Lawv muaj thermal expansion tsawg, uas txhais tau tias lawv yuav tsis tawg los yog warp nyob rau hauv siab - kub tej yam kev mob. Qhov no yog ib qho tseem ceeb vim hais tias nyob rau hauv ntau cov txheej txheem kev lag luam, qhov kub thiab txias tuaj yeem hloov pauv sai, thiab lub stopper uas tsis tuaj yeem tswj cov kev hloov pauv no tuaj yeem ua rau xau lossis lwm yam teeb meem.
Lwm qhov zoo ntawm peb cov Graphite Stoppers yog lawv cov tshuaj lom neeg ruaj khov. Lawv tiv taus corrosion los ntawm ntau cov tshuaj, uas yog ib qho loj ntxiv nyob rau hauv ib puag ncig uas muaj corrosive tshuaj. Qhov tshuaj lom neeg ruaj khov no tseem ua rau lawv cov kev ua haujlwm tag nrho thiab kev tiv thaiv hluav taws xob, vim tias nws tiv thaiv kev tsim ntawm cov chaw tsis muaj zog hauv cov khoom uas tuaj yeem ua kom yooj yim dua los ntawm hluav taws xob.
Yog tias koj nyob hauv kev ua lag luam rau Graphite Stoppers lossis lwm yam khoom siv graphite, peb tau txais koj them. Peb kuj muab ntau yam khoom muaj feem xyuam, xws li Graphite Crystallizer, Graphite Tube, thiab Graphite Degassing Rotor. Cov khoom no yog tsim los nrog tib lub siab - cov qauv zoo thiab hluav taws xob - resistant zog raws li peb cov Graphite Stoppers.
Graphite Crystallizer yog siv rau hauv cov hlau smelting los tswj cov txheej txheem solidification ntawm molten hlau. Nws cov hluav taws xob tiv thaiv kom ntseeg tau tias nws tuaj yeem ua haujlwm nyab xeeb hauv ib puag ncig uas muaj hluav taws xob tam sim no. Graphite Tube yog lwm qhov tseem ceeb, feem ntau siv los thauj cov hlau molten. Nws muaj peev xwm tiv taus hluav taws xob ua rau nws muaj kev ntseeg siab rau ntau daim ntawv thov kev lag luam. Thiab Graphite Degassing Rotor yog siv los tshem tawm cov pa roj los ntawm cov hlau molten, thiab nws cov hluav taws xob tiv thaiv yuav pab tswj nws cov kev ua tau zoo dhau sijhawm.
Yog tias koj xav paub ntxiv txog peb Graphite Stoppers lossis ib qho ntawm peb cov khoom lag luam, tsis txhob yig tiv tauj. Peb ib txwm zoo siab los teb koj cov lus nug thiab muab cov ntaub ntawv ntxiv rau koj. Txawm hais tias koj nyob hauv kev lag luam nuclear, hlau smelting, lossis lwm qhov chaw uas yuav tsum muaj hluav taws xob - cov khoom graphite resistant, peb tuaj yeem muab cov kev daws teeb meem rau koj.
Yog li, yog tias koj tab tom nrhiav rau siab - zoo, hluav taws xob - resistant Graphite Stoppers thiab lwm yam khoom, saib tsis muaj ntxiv. Hu rau peb hnub no los pib sib tham txog koj qhov kev xav tau tshwj xeeb. Peb cia siab tias peb cov khoom yuav ua tau raws li koj xav tau thiab tshaj qhov koj xav tau.
