Indlela yokufaka kahle ukugqwala emotweni ngezandla zakho
Okuqukethwe
Ukulungisa indawo encane (indawo egqwalile), ibhethri elilodwa “lomunwe” lanele. Kodwa qiniseka ukuthi uthatha i-saline, lapho umzimba wenziwa cishe i-zinc eyi-100%.
I-galvanizing imoto yenziwa ukuze kuvikelwe umzimba ekugqwaleni futhi kususwe izindawo ezigqwalile. Ungathenga ukwakheka okukhethekile noma usebenzise i-asidi nebhethri. Ake sithole indlela yokwenza ukugqwala kwemoto ngokwakho.
Indlela yokwenza ukugqwala emotweni ngokwakho
Ukuzigaxa umzimba wemoto, kusetshenziswa izindlela ezimbili:
- I-Galvanic. Ukuxhumana kugxilwe ebusweni bemoto kusetshenziswa i-electrochemistry.
- Kuyabanda. I-ejenti equkethe i-zinc isetshenziselwa ukugqwala komzimba okugqwalile.
Indlela yokuqala iyathandeka, ngoba i-zinc yakha ifilimu eminyene kakhulu kuphela ngaphansi kwethonya likagesi. I-Cold galvanizing kulula ukuyifeza, kodwa kamuva umzimba awuzinzile ekulimaleni komshini.
Egaraji kunzima kakhulu ukubuyisela ngokuphelele umzimba wemoto ngezandla zakho. Ezikhathini eziningi, indawo eyonakele ifakwa uthayela endaweni. Ngokuvamile, ama-threshold, ama-fenders emoto, i-bottom, ama-arch amasondo noma ukulimala kwamaphuzu kuyacutshungulwa.
I-Zinc isetshenziselwa ukubuyisela umzimba, ngoba ayibizi, ayigqwali futhi ihlala isikhathi eside.

Izigaba zomsebenzi nezinto zokwakha
Gcoba kuphela egalaji elinomoya omuhle, noma ngaphandle kangcono. Ukuze usebenzise indlela ye-galvanic engabizi kakhulu, uzodinga:
- ibhethri njengomthombo we-zinc;
- ucezu loboya bekotini noma i-cotton pad;
- i-tape kagesi kanye nocezu locingo olune "ngwenya";
- i-orthophosphoric acid;
- noma iyiphi i-metal degreaser;
- i-soda.
Ukulungisa indawo encane (indawo egqwalile), ibhethri elilodwa “lomunwe” lanele. Kodwa qiniseka ukuthi uthatha i-saline, lapho umzimba wenziwa cishe i-zinc eyi-100%.
Yonke inqubo yokukhipha indawo encane yokugqwala ithatha isigamu sehora:
- Susa ifilimu ebhethri, susa induku yegraphite nazo zonke izinto zangaphakathi.
- Ohlangothini oluhle, vunguza ucingo futhi uluvikele ngeteyipu kagesi.
- Vala isiphetho sebhethri ngoboya bekotini bese upheqa itheyiphu futhi.
- Xhuma "ingwenya" ngakolunye uhlangothi lwentambo kumatheminali ebhethri lemoto.
- Nciphisa indawo ephathwayo.
- Gcoba uboya bekotini kahle nge-asidi bese uncike ekugqwaleni. Uzobona ngokushesha ukuthi ukusabela kuqhubeka kanjani.
Ngesikhathi sokukhwabanisa, kwakhiwa umbhangqwana we-galvanic, lapho i-zinc esebenzayo yakha ifilimu eliminyene phezulu. Monisa uboya bekotini nge-asidi kaningi ngangokunokwenzeka ukuze ungqimba lube lukhulu.
Kuvame ukubuyekezwa ezinkundleni ukuthi akudingekile ukuhlanza ukugqwala. Yebo, yena ngokwakhe uzohamba ngokoqobo ngemva kwemizuzu emibili yokuchayeka ensimbi egqwalile. Kodwa kulokhu, i-zinc coating izolala kabi.
I-Acid yokugcoba imoto
I-Phosphoric acid ifaneleka kakhulu ekugayeleni. Isebenza njenge-electrolyte, ibhekana ne-rust deposits, i-oxides futhi ivimbele ukwakheka kwabo okulandelayo.
Uma ucubungula indawo enkulu yomzimba, khona-ke ukusheshisa inqubo, ungancibilikisa ishidi le-zinc elinesisindo esingu-100 g ku-100 ml we-asidi.
Amaphutha Angenzeka Lapho Ufaka Ukugqwala
Ngaphansi kwazo zonke izimo ze-galvanizing, kwakhiwa ifilimu ehlala isikhathi eside e-silvery ngaphezulu. Uma eba mnyama:
- noma akuvamile ukucwilisa ibhola likakotini ku-asidi;
- noma ilethe uhlangothi olunegethivu lwebhethri eduze kakhulu nebhethri.
Elinye iphutha ukukhohlwa ukwehlisa insimbi ngaphambi kwenqubo. I-Zinc isazokwenza ifilimu, kodwa ingase ihlehle ngemva konyaka. Ukwehlisa amafutha kukhulisa impilo yomzimba futhi kuvimbela ukugqwala lapho kucwecwa upende.
