Sib tsoo thiab xuab zeb daim kom txog thaum koj tau tshem ib qho thiab txhua qhov ua tiav. Koj yuav tsum pom tsuas yog cov hlau liab qab.
Kauj Ruam 2. Xaum tawm ib qho av
Yog tias muaj cov qhov hauv hlau, qhov no yog lub sijhawm los daws lawv. Siv koj lub tshuab ziab khaub ncaws los yog lub tshuab ziab khaub ncaws kom coj cov hlau nyob ib puag ncig lub qhov. Qhov no yuav ua rau cov hlau du thiab ua rau koj ua tiav zoo dua.
Kauj Ruam 3. Tsis txhob looj hnab looj tes
Hnab looj tes yuav tsis tsuas yog tiv thaiv koj txhais tes, tab sis lawv tseem yuav tiv thaiv cov hlau los ntawm koj txhais tes. Koj txhais tes yuav tso roj rau ntawm cov hlau uas cuam tshuam nrog cov txheej txheem bluing. Hnav cov hnab looj nitrile lossis hnab looj tes kom cov roj no tsis txhob ncav cuag cov hlau.
Kauj Ruam 4. Ntxuav cov hlau
Ntxuav cov hlau nrog cawv. Tom qab ntawd koj yuav tsum ua raws li kev ntxuav nws nrog cov ciab thiab cov roj tshem tawm (cov organic hnyav). Thaum kawg, siv daim ntaub mos muag los txhuam cov hlau.
Txoj Kev 2 ntawm 4: Txias Txias
Kauj Ruam 1. Thov tshuaj bluing

Txoj Kev 3 ntawm 4: Kub Kub
Kauj Ruam 1. Txhuam daim hauv dej txias
Muab cov khoom tso rau hauv dej txias thiab txhuam nrog cov ntaub plaub los yog cov ntaub qhwv. Qhov no yuav tsim qhov khawb me me rau qhov kev daws teeb meem bluing kom ua raws. Qhov no yuav tsum tau ua tom qab ib qho kev ua tiav raug tshem tawm thiab cov hlau tau raug ntxuav.
Kauj Ruam 2. Raus dej rau hauv daim ntsev
Kev daws teeb meem yog ua los ntawm cov poov tshuaj nitrite thiab sodium hydroxide yaj rau hauv dej. Kev daws yog rhaub kom kwv yees li 275 ° F (135 ° C). Koj yuav tsum tawm ntawm qhov chaw raus dej rau 15-30 feeb.
Kauj Ruam 3. Yaug daim hauv dej txias
Thaum koj tshem daim los ntawm qhov sib tov, muab nws tam sim rau hauv dej txias. Qhov no yuav ua rau cov hlau cog lus thiab xauv qhov ua tiav. Tsis txhob txhuam cov hlau dua.
Kauj Ruam 4. Yaug daim hauv dej npau
Boil dej dawb (tsis muaj ntsev). Muab cov hlau tso rau hauv cov dej npau. Qhov no yog theem kawg hauv txheej txheem bluing.
Kauj Ruam 5. Thov dej tshem cov roj
Tshem tawm cov dej los ntawm cov hlau yog qhov tseem ceeb. Muab qee cov dej tshem tawm cov roj rau ntawm daim ntaub mos muag thiab txhuam nws mus rau hauv cov hlau. Nws tseem yuav tawm ib txheej tiv thaiv cov hlau.
Txoj Kev 4 ntawm 4: Bluing Lwm Txoj Kev
Kauj Ruam 1. Rust xiav cov khoom qub
Rust bluing yog txheej txheem txheej hlau hauv cov kua qaub. Feem ntau, siv nitric acid lossis hydrochloric acid. Qhov no tso cai rau ib feem kom xeb tsis xwm yeem. Tom qab ntawd, koj txhuam cov xeb tawm thiab rov ua cov txheej txheem kom txog thaum cov xim xav tau ua tiav. Koj tuaj yeem ua qhov no hauv lub thawv loj lossis vat uas tiv taus cov kua qaub.
Kauj Ruam 2. Fume xiav rau qhov ua kom tiav
Fume bluing zoo ib yam li xeb xeb, tab sis nws tsim kom muaj xeb ntau dua. Ib feem tau muab tso rau hauv lub thawv cua txias thiab ib qho nitric acid lossis hydrochloric acid (gas) tau tso rau hauv chav. Cov pa ua rau tsis sib xws. Ib lub thawv ntim cua txias yuav ua haujlwm, tsuav nws tsis tuaj yeem raug corroded los ntawm cov kua qaub.
Kauj Ruam 3. Sim niter bluing
Niter bluing yog daim ntawv kub tshaj plaws ntawm bluing. Hauv qhov no, koj noj cov poov tshuaj nitrate ntsev thiab sodium hydroxide ntsev thiab yaj lawv (700 ° F (371 ° C).
Kauj Ruam 4. Hu rau tus kws tshaj lij
