Qhov tshwm sim tshwm sim ntawm cov pa luam yeeb dawb yog ib qho tshwm sim ntawm kev fab tshuaj. Cov tshwm sim sab saum toj ntawm txoj kab sim thaum ua haujlwm hauv chaw kuaj, nws qhia tias koj tau ua tiav kev sib txuam nrog tshuaj. Cov pa luam yeeb dawb nyob rau theem ua rau cov neeg tuaj saib tsis txaus ntseeg, tab sis yog tias nws los ntawm cov pa ntawm lub tsheb, lub sijhawm tau los xyuas qhov xwm txheej ntawm koj tus "plaub-wheeled phooj ywg".

Cov Lus Qhia
Kauj ruam 1
Koj tuaj yeem npaj qhov kev sib ntsib ntawm kev siv tshuaj lom neeg nrog cov tsos ntawm cov pa luam yeeb dawb hauv tsev. Muaj tseeb, qee qhov kev sim tau muab coj mus ua haujlwm sab nraum zoo lossis hauv qhov chaw muaj cua zoo, vim tias qhov tshuaj tiv thaiv ua rau cov tshuaj tsis yog cov txiaj ntsig zoo tshaj rau kev noj qab haus huv. Tso cov pa roj carbonate rau hauv ib lub hwj tshuaj. Nov yog qhov feem ntau cov potash uas koj tuaj yeem nrhiav ntawm cov khw muag khoom vaj khoom tsev. Tom qab sau tus txheem ntawm cov hwj nrog hydrochloric acid, koj yuav pom tuab dawb haus luam yeeb. Ib qho tshuaj tiv thaiv muaj tshwm sim, qhov tshwm sim ntawm cov pa dej uas tso tawm sai, uas yog pa luam yeeb dawb.

Tshem tawm cov dej khov qhuav hauv lub tub yees. Nws yog qhov tsim nyog rau kev paub dhau los uas muaj rau txhua tus neeg tiag tiag thiab dhau ntawm, muaj kev nyab xeeb kiag li. Tso dej siv ntawm tus kais dej tshaj plaws rau hauv lub khob. Zoo dua, tau kawg, siv cov distilled, tab sis nws kuj tsis tuaj yeem nyob ntawm tes. Tso cov dej khov rau hauv dej. Cov pa luam yeeb dawb yuav vau tam sim ntawd thiab sib zog heev. Hauv qhov no, nws yog dej vapor.
Kauj ruam 4
Kev sim nrog berthollet ntsev yog qhov zoo tshaj plaws ua rau sab nraum zoov. Txhawm rau ua kom muaj qhov ua kom yuam kev zoo sab hauv tsev, koj xav tau lub ntsej muag zoo. Nqa ammonia, naphthalene, berthollet ntsev thiab hluav ncaig hauv qhov sib piv ntawm 5: 2: 2: 1 thiab taws nws. Qhov muaj pes tsawg leeg nws tus kheej yuav tsis hlawv. Koj yuav xaus nrog cov tuab dawb haus luam yeeb yam tsis muaj hluav taws kub. Nws tsw tsw qab heev.
Kauj ruam 5
Cov pa luam yeeb dawb uas tsis muaj hluav taws tuaj yeem ua tiav nrog cov roj av paraffin thiab chromium oxide. Qhuav ib daig ntawm lub tswm ciab rau ntawm cov nplais ceramic. Sab saum toj nws nrog ntsuab chromium oxide hmoov. Nqa cov "magic wand", uas yog, phim. Yuav tsis muaj hluav taws, tab sis yuav muaj ntau ntawm cov pa luam yeeb dawb. Hauv qhov no, nws muaj cov lus me me ntawm paraffin.
Kauj Ruam 6
Yog tias pa luam yeeb dawb tawm ntawm lub yeeb nkab ntawm lub tsheb thaum lub caij ntuj sov thaum sov ua kom sov, txhua yam zoo. Thaum lub tshuab tso pa tseem tsis tau sov, cov dej muaj nyob hauv huab cua ua ntej tso thiab pib yaj. Ntxiv mus, qis dua huab cua kub, lub ncu tuab dua yuav ua.
Kauj Ruam 7
Cov pa luam yeeb dawb los ntawm cov pa hluav taws xob tuaj yeem tshwm sim nyob rau lub caij sov, thiab lub sijhawm ntawd thaum lub tshuab zoo li sov. Qhov no txhais tau tias coolant tau nkag mus rau hauv cov thooj voos kheej kheej. Cov sib xyaw ua ke ntawm cov kua no txiav txim siab tias cov pa khov tuab npaum li cas. Nco ntsoov tias cov roj tawm ua kua tseem tuaj yeem tsim cov pa luam yeeb dawb. Txhawm rau txiav txim siab qhov muaj pes tsawg leeg ntawm cov pa luam yeeb, tuav ib daim ntawv ze ntawm cov yeeb nkab tso pa. Nws yog txaus kom npog lub qhov rau ob peb feeb. Yog tias cov pa tawm hauv cov yeeb nkab, cov dej ntws tawm yuav tshwm rau ntawm daim ntawv, uas yuav yaj tau sai heev. Tseeb tiag, cov roj yuav ua rau lub nplooj tawv. Nyob rau hauv txhua rooj plaub, cov tsos ntawm cov pa luam yeeb dawb hauv huab cua sov thiab nrog lub cav sov qhia tias nws yog qhov yuav tsum tau los soj ntsuam qee cov kab ke tsheb.
