Dzimbiri Protection

mankhwala zitsulo pa nthawi pang'onopang'ono yokutidwa ndi patina dzimbiri. Yomanga anawononga pafupifupi inasanduka fumbi. Kupewa zotsatira sanakuchitireni, muyenera kudziwa zimene dzimbiri zitsulo ndi mmene kuteteza motsutsa izo. Zitsulo pansi pa kudzitsitsa chifukwa kukhudzana ndi chilengedwe kunja, umene uli electrochemically kapena mankhwala. Chemical dzimbiri zikuoneka pa TV sangathe kuchititsa ndi magetsi (mafuta, gasi, alcohols). Iye anaonekera kwa mwamtheradi onse zitsulo. Electrochemical dzimbiri kumachitika chifukwa yatsoka filimu electrolytic zitsulo chifukwa zinthu zachilengedwe. Makamaka, mmene-luso banja mchere ntchito m'misewu m'nyengo yozizira, ndi mafunde yosokera. Njira ndi njira imene amapangidwa dzimbiri, pali zambiri.

Wotchuka kwambiri ndipo yafika ntchito zokutira. Iwo anabwera mu zitsulo ndi mchere sanali zachitsulo. Wamkulu efficacy kupereka zokutira zochokera kulenga bodza ma polima kupanga. Mankwala sanali zachitsulo ❖ kuyanika ndi osiyanasiyana kwambiri. Zikuphatikizapo utoto (mafuta, alkyd ndi enamel) ndi vanishi (nkhuni phula, kupanga phula). Pamene ntchito zimenezi chitetezo dzimbiri amalenga woonda filimu kamodzi zitsulo ku chinyezi ndi zotsatira zachilengedwe. Penti ndi vanishi zosavuta ntchito, angakwanitse. Pa chiyambi cha ntchito m'pofunika kuti mosamalitsa kutsatira sayansi ya ntchito yawo. Tsamba loyamba la pamwamba zitsulo ndi zofunika mu zigawo zingapo bwino kuteteza nyumba chikoka chomwe mumlengalenga.

Zachitsulo zokutira zoletsa kusiyanitsa mitundu iwiri. Woyamba nsembe ❖ kuyanika monga cadmium, nthaka, zitsulo zotayidwa. The chachiwiri - dzimbiri zosagwira ❖ kuyanika mkuwa, siliva, kutsogolera faifi tambala ndi chromium.

Malinga ndi mmene limagwirira kanthu ali dzimbiri chitetezo, ilo likutchedwa cathode kapena anode. Pali zitsulo zokutira, zoletsa ndi electronegativity wamkulu, ndi zokutira kukhala electropositive mkulu. Anode zokutira a mtundu woyamba, cathode - kwa wachiwiri. Ntchito zotayidwa ndi nthaka, monga cathode monga anode zokutira - faifi tambala, mkuwa, tini.

njira zosiyanasiyana kuteteza zitsulo ndi dzimbiri muwone embodiments angapo ❖ kuyanika. Mwachitsanzo, chifukwa ntchito zoletsa mankhwala ntchito njira wokutira zachitsulo nyumba miyala ina: zotayidwa, nthaka.

Ngati kapangidwe zitsulo ali zacita, ndiye thandizani msanga chiwonongeko cha passivating zina ndi zoletsa. Zimathandiza chopinga njira dzimbiri mu zamchere ndi mapangidwe ndale oxidants cholimba monga zamchere lapansi ndi zitsulo soda. Kuteteza zolimba mu analimbitsa simenti, ntchito kashiamu nitrate-nitrite.

Pamene inu tifunika kutetezedwa ku dzimbiri, zikuchitika mchikakamizo cha chilengedwe kunja ndi mpweya mumlengalenga, ntchito zoletsa oyaka, amene ali zipangizo zimene adsorb kuyenda pamwamba zitsulo mpweya kapena Zachepetsedwa adalira kupanga wosanjikiza woonda.
