Ib hom khoom caustic soda (sodium hydroxide) khoom, tshuaj formula: NaOH. Raws li qhov loj me, nws tuaj yeem muab faib ua coarse-grained alkali thiab particulate alkali, ntawm cov particle loj ntawm particulate alkali yog li ntawm 0.7mm, thiab cov duab zoo ib yam li ntxuav hmoov. Ntawm cov khoom alkalis, caustic soda thiab caustic soda yog siv ntau thiab siv cov dej qab zib caustic, thaum caustic soda zoo dua li caustic soda, tab sis cov txheej txheem ntawm caustic soda yog qhov nyuaj thiab nyuaj tshaj li caustic soda. Yog li ntawd, tus nqi ntawm caustic soda yog ib txwm siab dua li ntawm caustic soda.
Ntxiv nrog rau kev siv hauv kev lag luam thiab kev tsim kho kev lag luam, flake alkali kuj tseem siv tau los ua tus neeg saib xyuas kom ntxuav cov roj, thiab cov nyhuv yog pom tseeb. Ib lub hood xav tau 100 grams caustic soda, siv lub tais yas uas tuaj yeem tuav lub log cua, sau ib nrab ntawm cov dej kub, thiab ntxiv cov dej qab zib caustic los ua potion. Tom qab ntawd tshem tawm cov cua log, muab tso rau hauv potion thiab tsau rau tsib los yog rau feeb, thiab tig nws mus rau soaking. Los ntawm soaking, yuav luag tag nrho cov roj yog poob, thiab ces yaug nrog dej huv, uas yog, huv si.
Tom qab cov cua tshuab ntxuav, cov dej lye siv tau tuaj yeem ntxuav lub tshuab tshuab: muab cov hnab looj tes roj hmab, siv cov pob steel, rub lub thawv tshuab, thiab tom qab ntawd so nrog cov ntaub qhwv qhuav. Lub lim yuav tsum tau tsau rau hauv potion rau ib pliag, thiab tom qab ntawd txhuam nrog txhuam hniav. Tom qab ntawd, cov rags thiab cov pob hlau tau muab pov rau hauv potion npaj nrog caustic soda rau ib pliag, thiab muab tso rau hauv dej huv, thiab lawv zoo li tshiab dua.
