Thaum siv cov pa hluav taws xob liab liab, koj yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:
Kev ntxuav thiab kev npaj: ua ntej siv cov roj cua kub taub hau, saum npoo ntawm cov yeeb nkab hlau yuav tsum tau ntxuav thiab huv si. Tom qab ntawd degrease cov yeeb nkab hlau thiab muab tso rau hauv cov kua degreasing nrog tus nqi ntawm 13 rau tsis pub tsawg tshaj li ib nrab ib teev. Tom qab degreasing, ntxuav nrog dej huv thiab tom qab ntawd pickle. Tus nqi ntawm tus nqi ntawm cov kua uas tuaj yeem yog li ntawm 3 thiab lub sijhawm kho mob tsis pub tshaj 10 feeb. Thaum kawg, kev kho cov xim dub ua. Tus lej pH ntawm lub pas dej ua pa ua pa yog nruab nrab ntawm 2-4. Lub sijhawm kho yog li 10 feeb. Nws yuav tsum tau ntxuav tom qab blackening.
Kev txhim kho thiab kho: lub tshuab ua kom lub tshuab cua tooj liab yuav tsum tau muab tso rau kom ntseeg tau tias qhov chaw ua kom sov tau muab raus hauv cov kua lossis cov khib nyiab hlau. Kev nchuav hluav taws xob. Yog tias ntsuas lossis cov pa roj carbon nyob ntawm cov yeeb nkab lub cev, nws yuav tsum tau ntxuav kom tsis txhob cuam tshuam rau cov nyhuv kub dissipation nyhuv thiab lub neej pabcuam.
Kev tu thiab saib xyuas: thaum siv, nws yog qhov tsim nyog yuav tsum tsis tu ncua ntxuav cov hmoov av nyob rau saum npoo ntawm tooj liab cov yeeb nkab kom tswj nws cov nyhuv kub dissipation nyhuv. Hmoov tsis zoo rau cov cua sov dissipation thiab volatilization ntawm cov kav dej tshav kub, yog li lawv yuav tsum tau ntxuav kom huv tsis tu ncua, tshwj xeeb tshaj yog nyob hauv ib puag ncig hnyav. Muaj feem xyuam nrog cov xwm txheej thiab cov kev txwv: tooj liab cov tso tsheb hlau luam yeeb, tso tsheb hlau luam, acid thiab alkali tso tsheb hlau luam thiab lwm yam khoom siv alkali. Lawv muaj cov yam ntxwv ntawm cov qauv yooj yim, muaj zog dua, muaj kev nyab xeeb thiab kev ntseeg tau yooj yim, thiab lub neej ntev. Txawm li cas los xij, Flattening thiab dabtsi yog khoov yuav muaj kev tsis zoo rau kev ua haujlwm ntawm cov kav kub, koj yuav tsum tau them sai sai rau kev cuam tshuam ntawm cov kev cuam tshuam ntawm cov haujlwm no.
