Kev sib cuag ncaj qha tuaj yeem ua rau kub hnyiab tau yooj yim. Nws yog qhov yuav tsum tau hnav khaub ncaws tiv thaiv, hnab looj tes tiv thaiv thiab tsom iav thoob plaws hauv cov txheej txheem, thiab ua kom qhov chaw ua haujlwm muaj cua zoo kom tiv thaiv kev sib sau ua ke ntawm cov pa phem acid hauv qhov chaw kaw. Hauv qab no yog kev piav qhia txog kev siv thiab koob tshuaj raws li ntau qhov xwm txheej, nrog rau kev hloov kho yooj yim rau cov piv thiab cov nqi dilution hauv kev siv hauv kev lag luam.
Kev tshem tawm xeb hlau:Npaj ib qho kev daws teeb meem nrog qhov concentration ntawm 8%–12% (ua kom muaj zog dua hauv qhov chaw alkaline kub heev). Yaj 800 g txog 1.2 kg ntawm oxalic acid hmoov lossis cov siv lead ua rau hauv txhua 10 kg dej huv. Tsuag cov tshuaj ob zaug rau ntawm qhov chaw ntawm cov khoom siv loj lossis cov kav dej kom tau txiaj ntsig ruaj khov, nrog rau lub sijhawm teb ib zaug li 15 feeb. Tom qab so, yaug nrog dej huv kom txog thaum tsis muaj zog kom tiv thaiv cov kua qaub seem los ntawm cov khoom xeb.
Cov khoom siv pabcuam luam ntawv thiab zas xim: Cov kauj ruam yaj yog qhov tseem ceeb heev. Nyob rau hauv qhov siab ib txwm thiab qhov kub siab (80 ° C–100 ° C), siv 15 L ntawm cov kua qaub oxalic (3% concentration) rau ib lub cubic meter ntawm cov ntaub. Muab cov ntaub tso rau hauv cov khoom siv nruas kom txog thaum cov tshuaj nkag mus rau hauv cov fibers, tom qab ntawd kho rau 8-12 feeb. Saib xyuas qhov tsis zoo thiab cov ntaub hloov pauv hauv lub sijhawm tiag tiag.
Rau kev siv hauv tsev neeg, cov tshuaj yuav tsum tau txo kom tsawg dua kom tsis txhob muaj kev pheej hmoo rau kev noj qab haus huv:
Yuav ntxuav cov vuas chav dej, siv cov tshuaj uas muaj 1%–1.5%. Feem ntau, yaj 40–60 g ntawm cov oxalic acid blocks rau hauv 2 L dej huv, cia nws nyob rau ntawm qhov chaw tsis pub dhau 3 feeb, tom qab ntawd txhuam nrog txhuam tawv.
Rau cov kab xeb tawv ncauj ntawm cov vuas hauv pem teb uas muaj thaj chaw me me, ncaj qha thov cov tshuaj pleev kom npog cov cim thiab yaug nrog dej huv hauv 5 feeb.
Nco ntsoov tias tom qab ntxuav nrog oxalic acid, feem ntau yuav muaj txheej roj nplaum rau ntawm cov pobzeb, ua rau pom tsis meej. Nws raug nquahu kom siv cov tshuaj txhuam hniav lossis dej xab npum nruab nrab kom ua rau cov pobzeb du.
