Cov Xwm Txheej Nyuaj: Kev Xeb Hnyav thiab Kev Pheej Hmoo Siab ntawm Kev Thaiv
Hauv ib lub chaw ua lag luam tshuaj lom neeg loj hauv Sab Hnub Tuaj Suav teb, lub chaw ua khoom siv raw cov khoom siv rov qab ua kua qaub ua ntej lub twj tso kua mis feem ntau ua tsis tiav. Cov khoom nruab nrab yog dilute hydrochloric acid uas muaj me ntsis ntawm cov xeb me me thiab cov khoom siv ntsev ntsev. Cov xwm txheej ua haujlwm tau piav qhia los ntawmxeb heevthiabyooj yim crystallization. Phab ntsa sab hauv ntawm lub lim dej carbon steel qub qub tau xeb heev, thiab lub lim dej feem ntau raug txhaws nrog cov ntsev siv lead ua. Nws yuav tsum tau kaw kom hloov pauv txhua ob lub lis piam, ua rau cov nqi kho mob siab thiab cuam tshuam rau kev tsim khoom tas mus li.
Kev kho kom raug: Ob qho kev txhawb zog ntawm cov ntaub ntawv thiab cov qauv
Rau qhov chaw muaj xeb heev no, es tsis txhob hloov mus siv cov hlau tsis xeb tag nrho (uas yuav kim heev), peb tau kho ib qho kev daws teeb meem rau tus neeg siv khoom, uas muaj lub cev tseem ceeb carbon steel nrog lub txheej sab hauv tshwj xeeb rau kev tiv thaiv xeb.
Cov ntaub thaiv tshwj xeeb tiv thaiv xeb: Ntawm phab ntsa sab hauv ntawm cov lim hlau carbon thiab qhov chaw ntawm lub pob tawb lim, cov txheej txheem sintered spraying PTFE (polytetrafluoroethylene) tau txais yuav. Cov txheej txheem no tuaj yeem tiv thaiv cov xov xwm corrosive kom tsis txhob sib cuag nrog cov hlau carbon substrate, tiv taus hydrochloric acid corrosion, thiab tib lub sijhawm muaj qhov chaw du, uas txo qhov adhesion thiab scaling ntawm cov ntsev siv lead ua.
Kev tsim qauv txhawb nqaYuav kom daws tau qhov teeb meem ntawm kev thaiv, peb tau tsim lub pob tawb lim nrog lub hauv qab conical loj thiab lub cev loj, thiab kuj tau nthuav dav thaj chaw ntws thiab txuas ntxiv lub voj voog lim dej zoo.
Kev sib npaug ntawm kev lag luam: Thaum ua kom ntseeg tau tias muaj kev tiv thaiv xeb, kev daws teeb meem ntawm kev siv cov hlau carbon substrate nrog PTFE txheej ua rau txo nqi kwv yees li 40% piv rau kev siv cov hlau tsis xeb 316L tiav. Qhov no muab rau cov neeg siv khoom nrog kev xaiv pheej yig heev.
Cov txiaj ntsig ntawm daim ntawv thov: Los ntawm cov khoom siv tau mus rau cov khoom ruaj khov
- Kev ncua sijhawm ntev ntawm lub neejLub voj voog hloov lim tau ncua ntxiv los ntawm 2 lub lis piam mus rau ntau tshaj 6 lub hlis, thiab tus nqi ntawm cov khoom seem thiab kev tswj hwm tau raug txo qis heev.
- Cov nqi kho tau raug txo qis: kev kaw tsis tau npaj tseg vim yog qhov xau xeb thiab kev saib xyuas cov kav dej tau raug tshem tawm tag nrho.
- Kev lav phib xaub ntawm kev tsim khoom: Qhov kev ruaj khov ntawm kev ua haujlwm ntawm ntu no tau raug txhim kho zoo heev, ua rau nws yog ib qho kev daws teeb meem rau cov neeg siv khoom hauv kev lim cov xov xwm corrosive.
Cov lus tawm tswv yim los ntawm cov neeg siv khoom: "Tus nqi ntawm kev siv cov hlau carbon zoo ib yam li cov hlau tsis xeb uas tiv taus xeb. Cov kev daws teeb meem no daws tau peb cov teeb meem thiab qhia txog lub zog ntawm kev xaiv thiab tsim qauv tshaj lij."
