Qhov teeb meem ntawm lub ntsiab lus yog deb ntawm kaw. Nws yuav nyuaj rau yog qhov zoo yog tias nyob hauv cov khw muag cov hniav nyiaj hniav kub es tsis txhob siv cov khoom kim kub uas lawv xav kom koj xaum koj qhov cuav tseeb. Nws tsis yog qhov kev txaus siab ntawm qhov cov hlau tsis muaj lub tsheb tawg lossis cov khoom qub puas tau tsim los?
Cov Lus Qhia
Kauj ruam 1
Ntawm no, piv txwv li, yog yuav ua li cas lub tooj liab nyob rau hauv ib qho alloy yog txiav txim siab. Thov ib qho poob ntawm nitric acid tov (1: 1) rau cov hlau huv. Raws li qhov tshwm sim, cov roj yuav pib hloov zuj zuj. Tom qab ob peb lub vib nas this, blot qhov poob nrog cov ntawv lim, tom qab ntawd tuav nws hla lub hwj uas qhov cov tshuaj ammonia nyob hauv. Lub tooj liab yuav cuam tshuam los ntawm dyeing qhov stain ib qho xiav xiav tob.

Thiab ntawm no yog yuav ua li cas paub qhov txawv tooj ntawm tooj dag. Muab ib daim hlau hlaws lossis sawdust tso rau hauv lub beaker nrog 10 ml ntawm ib qho kev tov (1: 1) ntawm nitric acid thiab npog nws nrog iav. Tos me ntsis rau cov hlau kom yaj kom yaj, thiab tom qab ntawd ua kom sov cov kua uas ua tiav rau yuav luag rhaub rau 10-12 feeb. Ntub dej dawb yuav ua rau koj nco qab txog tooj dag, thiab ib tus neeg ua ci nrog tooj dag yuav ua kom pob tshab.

Koj tuaj yeem txheeb xyuas nickel nyob rau ntau qhov zoo ib yam li tooj liab. Thov ib qho kev poob ntawm nitric acid tov (1: 1) rau saum npoo hlau thiab tos li 10-15 feeb. Blot qhov poob nrog cov ntawv lim thiab tom qab ntawd tuav nws tshaj concentrated ammonia vapor. Txog ntawm lub ntsej muag tsaus nti, tso ib 1% daws ntawm dimethylglyoxin hauv cawv.
Kauj ruam 4
Nickel yuav "teeb liab" koj nrog nws tus xeeb ceem xim liab. Cov hmoov txhuas tuaj yeem txiav txim siab siv cov muaju ntawm chromic acid thiab ib tee dej ntawm txias acetic acid tso rau ntawm nws, thiab ib feeb tom qab - poob dej. Yog tias koj pom lub caij nplooj zeeg daj, paub tias nws yog lead txhuas.
Kauj ruam 5
Txhawm rau kom tsis txhob kub siab rau kub, piv txwv li, nrog tooj dag, thov ib qho kev daws ntawm nitric acid (1: 1) rau saum npoo. Yog tias tsis muaj qhov tshuaj tiv thaiv, xav txog koj tus kheej muaj hmoo - cov ntsiab lus kub hauv cov hlau ntau dhau 25%.
Kauj Ruam 6
Kev txiav txim siab qhov muaj hlau kuj yooj yim. Nqa ib daim ntawv ntawm hlau thiab kub nws hauv hydrochloric acid. Yog tias qhov txiaj ntsig yog qhov zoo, cov ntsiab lus ntawm lub hwj yuav tsum tig daj. Yog tias koj muaj qhov tsis txaus ntseeg nrog chemistry, muab cov hlau nplaum tsis tu ncua. Nco ntsoov tias tag nrho cov hlau ferrous alloys tau nyiam rau nws.
