Piav qhia yog cov txheej txheem ntawm txoj kev nrawm, pheej yig thiab muaj kev nyab xeeb rau etch luam tawm lub rooj tsavxwm siv cov cuab yeej muaj nyob ntawm tes - ntsev, hydrogen peroxide thiab citric acid.

Tsim nyog

  • - citric acid - 1 pob ntawv;
  • - hydrogen peroxide 3% - 1 lub raj mis 100 ml;
  • - rooj ntsev - 2 me nyuam diav.

Cov Lus Qhia

Kauj ruam 1

Cia peb nqa lub ntim khoom tsim nyog rau etching lub rooj tsavxwm, kom lub rooj tsavxwm mus rau ntawd. Ntxiv 1 teaspoon ntsev, 30 g ntawm citric acid, ib nrab lub raj mis ntawm hydrogen peroxide. Sib tov kom huv si kom txog thaum cov ntsev thiab cov kua qaub tag yaj rau hauv peroxide. Txoj kev daws teeb meem no yog kev nyab xeeb rau tib neeg - nws tsis xeb ntawm daim tawv nqaij thiab khaub ncaws, tab sis tooj liab lom zoo kawg nkaus.

Peb muab tso rau hauv lub ntim rau ntawm seem ntawm cov ntawv luam Circuit Court nrog cov ciav hlau ua ntawv thov, piv txwv li, los ntawm "laser-ironing" method. Peb tau sib tham txog hom no los npaj pawg thawj coj hauv kev qhia hauv ib qho ntawm cov ntawv sau dhau los.

Kauj ruam 3

Tam sim no peb tos kom txog thaum cov kua qaub etches tsis tiv thaiv thaj chaw ntawm tooj liab. Nyob ntawm qhov tuab ntawm txheej tooj liab, qhov no tuaj yeem siv sijhawm li ib nrab ib teev txog 1.5 teev. Nws yog qhov zoo dua tsis cuam tshuam nrog txoj kev, tab sis tsuas yog kom paub tseeb tias txhua yam yuav mus raws li nws yuav tsum. Tom qab ob peb feeb, koj yuav pom cov seething thiab nquag tsim cov pa npuas nyob rau saum npoo ntawm pawg thawj coj, thiab tom qab 10 feeb kev daws yuav pib tig xiav - ntsuab: nws txhais tau tias tshuaj lom neeg cov tshuaj tiv thaiv mus zoo.

Kauj ruam 4

Thaum lub etching tiav lawm, peb tso cov tshuaj siv thiab coj tawm ntawm lub rooj tsavxwm. Nws raug nquahu kom yaug lub rooj tsavxwm nrog cov tshuaj uas tsis muaj zog ntawm cov kua qaub, thiab tom qab ntawd nrog dej sov. Peb tshem tawm cov lem ntawm lub toner. Nws tseem tsuas yog yuav tsum tau ntiav lub ntsuas phoo tiv tauj thiab daim npav hluav taws xob luam tawm uas siv tau!
