Kev ntxuav nyiaj npib nyiaj yog ib txoj hauv kev ntawm kev tshem tawm cov plua plav, plua plav, lossis hlau oxidation los ntawm nws cov nplaim, thiab muaj ob peb txoj hauv kev huv rau cov nyiaj npib nyiaj kom zoo thiab yooj yim.
Tsim nyog
- - Cov txhuam muag muag lossis txhuam;
- - ammonia;
- - ci dej qab zib;
- - Tshuaj txhuam hniav;
- - 10% daws ntawm Trilon B;
- - ntxhua khaub ncaws;
- - kua txiv qaub;
- - txhais tau tias kev siv tshuaj hauv tsev nrog hydrochloric lossis oxalic acid (piv txwv li Silit thiab Silit Bang).
Cov Lus Qhia
Kauj ruam 1
Yog tias cov nyiaj npib nyiaj tsuas kis tau yooj yim nrog cov plua plav lossis av, nws yuav tsum tau muab yaug hauv cov dej sov uas siv tus txhuam muag los yog txhuam hniav yooj yim.
Kauj ruam 2
Txog cov nyiaj npib, yuav tsum paub qhov zoo ntawm cov nyiaj npib. Cov kev ua kom huv yuav nyob ntawm tus qauv.
Kauj ruam 3
Koj tuaj yeem ntxuav qhov nyiaj npib-theem zoo nrog qhov khoob ntawm ammonia - nws muag hauv txhua lub tsev muag tshuaj -, ci dej qab zib thiab tshuaj txhuam hniav. Cov sib xyaw no yuav tsum tau ua kua thiab tsis muaj qhov nyuaj lossis abrasive hais. Nws yog qhov zoo dua los siv cov tshuaj txhuam hniav ntawm kev lag luam hauv tsev, vim tias nws muaj cov tshuaj silicon oxide, nws tsis tawm qhov khawb me me, tsis zoo li calcium carbonate uas muaj nyob hauv cov tshuaj txhuam hniav txawv teb chaws.
Kauj ruam 4
Kev daws teeb meem 10% ntawm Trilon B yog qhov tsim nyog los ntxuav tu npib nyiaj tsawg. Nws yuav tsum muaj txhuam nrog txhuam muag muag thiab txhuam me ntsis, tom qab ntawd yaug cov kis nrog dej ntws thiab qhuav.
Kauj ruam 5
Lwm txoj hauv kev zoo los ntxuav cov nyiaj npib nyiaj tsawg yog nqus cov npib hauv dej sov thiab diluted khaub ncaws ntxhua khaub ncaws lossis kua txiv qaub. Hauv qhov no, cov nyiaj npib yuav tsum muab raus tag nrho hauv cov tshuaj siv. Lawv yuav tsum tsis txhob nkag hauv huab cua. Npib yuav tsum tau ntxeev nyob rau hauv ntau qhov kev daws teeb meem.
Kauj Ruam 6
Qhov yooj yim txoj kev los tiv thaiv oxides yog rub lawv nrog ci dej qab zib. Cov dej qab zib ci yuav tsum tau me ntsis moistened nrog dej thiab rubbed on lub npib nyiaj kom tshem tawm cov oxides.
Kauj Ruam 7
Qee tus numismatists siv tshuaj lom neeg hauv tsev nrog hydrochloric lossis oxalic acid. Cov khoom lag luam yaj tawm oxides hauv ob peb feeb, tab sis kuj rhuav tshem cov patina tsaus, ua rau cov npib ci.
Kauj ruam 8
Thaum ntxuav cov nyiaj npib, koj siv tsis tau:
1. Cov tshuaj daws cov ntsiab lus ntawm sulfuric, acetic, hydrochloric lossis nitric acids. Lawv yaj lub npov nyiaj ntawm npib;
2. Kev tsim kho cov tawv nqaij. Lawv tshem cov patina thiab minting ntawm npib;
3. Ib txoj kev ntsuas kub sib txawv, thaum cov nyiaj npib yog kub dua li hluav taws, thiab tom qab ntawd nws tau quenched hauv dej txias. Qhov no ua rau poob patina rau ntawm npib;
4. Cov txhuam nrog cov hlau txhuam. Lawv tshem tus qauv ntawm lub npib thiab "patina".
