I-Garvanization yomzimba wemoto: izindlela zokuvundisa
Ngemuva kokufaka isicelo ebusweni, isifutho somile ngokuphelele kungakapheli imizuzu engama-20-30. Ngokuya ngezimo zokusebenza zomshini kanye nenani lezingqimba ezisetshenzisiwe, ukugqoka kuzovikela umzimba wemoto iminyaka engu-10-50. Ngakho-ke, le ndlela yokwenza i-galvanizing ingabhekwa ngokuphepha njengelula kakhulu futhi elula ukuyisebenzisa.
Ukukhethwa kwezindlela ezithembekile zokuqinisa umzimba wemoto kuyisidingo sokusebenza isikhathi eside kwezimoto. Ukusetshenziswa okufika ngesikhathi komuthi kukuvumela ukuthi ukwandise impilo yesevisi yengxenye ebiza kakhulu yomshini.
Indlela elula nephumelela kakhulu
Kungakhathaliseki ukuthi ikhwalithi yefektri i-galvanizing, inqubo ivikela kahle insimbi kuphela uma umsebenzi wokupenda ungonakalisiwe. Ngisho nama-chips amancane, imihuzuko, inqubo ye-oxidation nokugqwala kwenzeka. Umphumela uba ukugqwala. Ezimweni zokukhiqiza, i-galvanic noma i-hot-dip galvanizing isetshenziswa nezingxenye ezicwiliswe kubhavu we-electrolyte.
Ngesikhathi sokulungiswa kwemoto, akunakwenzeka ukusebenzisa izindlela ezinjalo.
Phakathi kwezinzuzo zokusebenzisa indlela yilezi:
- lula kanye nesivinini sokusebenzisa umuthi emzimbeni wemoto;
- asikho isidingo sokulungiswa kokuqala kokubunjwa - vele ushukumise ithini;
- ukupakisha kuhle ukucubungula izindawo ezincane;
- awekho amathuluzi engeziwe adingekayo wokufaka isicelo.
Ngaphezu kwalokho, kufanele kuqashelwe ukusetshenziswa komnotho kokubunjwa kanye nokunemba kwesicelo, okubalulekile lapho uvikela izindawo ezinama-chips amancane noma imihuzuko.
Izindlela zokuvundisa
Indlela ye-aerosol yokucubungula insimbi iyasebenza. Kodwa-ke, kuphela uma izindlela ezikhethiwe zokugcoba umzimba wemoto zihlangabezana nezidingo eziningi:
- uketshezi luqukethe ngaphezu kwama-94% wento;
- i-powder iqukethe izinhlayiya ezi-oval noma eziyindilinga, ubumsulwa budlula ama-98%;
- inikeza umgoqo kanye nokuvikelwa kwe-cathodic.

Ngemuva kokufaka isicelo ebusweni, isifutho somile ngokuphelele kungakapheli imizuzu engama-20-30. Ngokuya ngezimo zokusebenza zomshini kanye nenani lezingqimba ezisetshenzisiwe, ukugqoka kuzovikela umzimba wemoto iminyaka engu-10-50. Ngakho-ke, le ndlela yokwenza i-galvanizing ingabhekwa ngokuphepha njengelula kakhulu futhi elula ukuyisebenzisa.
Ukucutshungulwa kwensimbi ekhaya
Enye yezindlela eziphumelelayo "zegaraji" kwakuwukusetshenziswa kwesisombululo se-zinc ku-phosphoric acid, namabhethri kasawoti esimweni se-zinc: usayizi uncike endaweni ephathwayo.
Abalungisi batusa ukwenza lokhu okulandelayo:
- Hlanza ingxenye noma ishidi lensimbi ngaphambi kokufaka umkhiqizo, susa ukugqwala.
- Khipha umluko ebhethrini.
- Ngebhande lokunwebeka, lungisa i-cotton pad ngakolunye uhlangothi, ngakolunye - intambo yamandla exhunywe ebhethri yemoto.
- "Minus" xhuma kuleyo ngxenye yemoto.
- "Plus" xhuma kuntambo eya kukesi lebhethri.
- Gcoba i-cotton pad ngesisombululo se-zinc ku-phosphoric acid.
- Ngokuqhubekayo, ngesivinini esifanayo, hambisa ikesi lebhethri ngaphezulu ukuze lilashwe. Kulokhu, uketshezi oluphumayo luzosatshalaliswa ngokulinganayo.
Ukuma, ukubambezeleka endaweni eyodwa kungaholela ekuveleni kokusha, okubuye kudingeke ukuthi kuqedwe. Ngakho-ke ungakwenza ngokwakho ukuvikela izingxenye zensimbi ekugqwaleni ngaphandle kwezindleko zezimali. Naphezu kweqiniso lokuthi le ndlela ibukeka iyingcweti ngandlela-thile, ifakazele ukuthi iyasebenza ekusebenzeni. Ngakho-ke, inketho iyaqhubeka nokusetshenziswa abanikazi bezimoto eMoscow nakwezinye izifunda kanye nezindlela zefekthri zokuqinisa umzimba wemoto.
