Iziguquli zokugqwala i-Hi-Gear
Okuqukethwe
Ukwakhiwa
Isenzo esifanayo siyadingeka kunoma yisiphi isiguquli sokugqwala: ngokusebenzisa i-asidi equkethwe emkhiqizweni, ukugqwala okungaphezulu kufanele kuguqulwe kube usawoti ongancibiliki. Lo sawoti, ohlelweni lokumiswa kwemvelo, uphenduka ube yi-primer efanelekile njengesisekelo sokudweba okungaphezulu okulandelayo. Ezinye izingxenye yilezi:
- ama-corrosion inhibitors.
- Amagwebu asiza ukususwa kwezinsalela zokugqwala.
- Izincibilikisi.
- ukwakheka kwezinzisi.
Abakhiqizi bethula izinhlobo ezahlukene zama-asidi ekwakhiweni kweziguquli zokugqwala. Ikakhulukazi, abaguquli bokugqwala Fenom, Tsinkar aqukethe hydrochloric acid. Isebenza kakhulu, kodwa idinga ukususwa okwengeziwe ngemva kokufakwa phezulu. Uma kungenjalo, ama-acids angena kalula emifantwini nasemigodini, edala umonakalo ezindaweni "ezinempilo" zokugqoka.
Iziguquli zokugqwala ezivela ku-Hi-Gear zisebenza ngendlela ehlukile. Ziqukethe i-phosphoric acid engasebenzi kancane, esebenza kancane, kodwa wonke umsebenzi olandelayo ungenziwa nganoma yisiphi isikhathi. Lokhu kushintshwa kokusebenza kunomthelela ekuguquleni ukugqwala okuphelele nokunamathela kwenhlabathi ku-substrate.
Izinhlobo ezidume kakhulu zokuguqula ukugqwala i-Hi-Gear
Izingoma ezine ezaziwa kakhulu yimikhiqizo ethi NO RUST, eqokiwe HG5718, HG5719, HG40 kanye ne-HG5721. Umehluko phakathi kwabo umi kanje:
- I-HG5718 isebenza kumgomo wokunamathela, okhuthaza ukuguqulwa kokugqwala ukusuka phezulu kuye ekujuleni. Ithuluzi linezici ezingenawo amanzi, ngemva kokumisa lakha ifilimu eqinile. Ngokweqile, imoto ayikwazi ngisho nokupenda (noma kunjalo, ngemuva kokucubungula, ubuso bomzimba buba mnyama grey);
- I-HG5719 isebenza ngobumnene, futhi isetshenziswa ezingqimbeni eziningana (kodwa zingabi ngaphezu kwezintathu). Ukudweba ngemva kokulungela kuyimpoqo, nakuba ukugqoka okuqediwe, ngenxa yokugxila okuphezulu kwezingxenye, kubonakala ngokunyuka kokumelana nemiphumela yamakhemikhali asebenzayo;
- I-HG5721 ne-HG40 yilokho okubizwa ngokuthi iziguquli zokungena. Zisetshenziswa ngokuqina okuphawulekayo kwamabala okugqwala, ine (ngokungafani ne-Tsinkar) umphumela ongangeni manzi, kodwa idinga ukudweba kwendawo ngokushesha ngemva kokuba ifilimu yomile.
Lonke uhla lwemikhiqizo eklanyelwe ukuguqula ukugqwala kumkhiqizo we-Hi-Gear lusebenza kahle ezingeni lokushisa elilinganiselwe - ukusuka ku-10 kuye ku-30 °C. Lokhu kungenxa yezakhiwo ze-physicochemical ze-phosphoric acid. Emazingeni okushisa aphezulu, ingakwazi ukusebenzisana ngenkuthalo notshwala, futhi emazingeni okushisa aphansi ilahlekelwa amandla ayo okugqwala.
Imiyalo yokusetshenziswa
Indawo okumele ihlanzwe kumele ihlanzwe kahle ingagqwali. Ukuhlanza ngemishini kusetshenziswa ngamabhulashi ensimbi (amabala amancane okugqwala angasuswa futhi nge-sandpaper enamahhadla).
Ngemuva kokugubha kakhulu i-can, i-ejenti iqondiswe ensimbi ukusuka ebangeni le-150 ... 200 mm. Ngesikhathi esifanayo, bazama ukuvimbela izimali ukuthi zingangeni ezindaweni ezingonakalisiwe. Ukucubungula ngesikhawu se-20 ... imizuzu engu-30 kufanele kuphindwe. Kusukela kumpendulo yomsebenzisi, kulandela ukuthi ngebanga elikhulayo, ukusetshenziswa kwezimali okungenakukhiqiza kuyakhuphuka. Ukucaciswa okubalulekile, ngoba izindleko zazo zonke iziguquli zokugqwala ezivela ku-Hi-Gear ziphakeme ngokuphawulekayo kune-Tsinkar efanayo.
Ngemuva kokumisa okuphelele (kwenzeka ngokwesilinganiso ngemva kwemizuzu engama-30), indawo engaphezulu ingapendwa: ifilimu eyenziwe yi-hygroscopic futhi ibambe upende kahle. Lapho becubungula, bazama ukuhambisa ithini ngokulinganayo ngangokunokwenzeka; uma ama-smudges enza, kufanele asuswe ngokushesha usebenzisa i-ethyl alcohol.
