Kusho zokususa nokugqwala kusuka metal: izindlela eziyisisekelo futhi izinto

nokugqwala Ngokuthi livela phezu kwensimbi nabo umoya namanzi-oxide. Ukuthola ku yensimbi, steel, nethusi, nokunye. N. Izinto izindawo abomvu, kufanele kuthathwe izinyathelo ngokushesha. Iqiniso liwukuthi i-okuqhubekayo namachibi inqubo iyashesha kakhulu. Ngenhlanhla, izindlela ekususeni nokugqwala ensimbi, kunezindlela eziningi. Ubuchwepheshe ikakhulukazi lincike ohlotsheni surface ziphathwe, kanye nezinga lesion t. D.

Izindlela eyinhloko ukususwa

Ukuze ekwelapheni surface metal kusuka ukugqwala ingasetshenziswa:

• lokukhuhla, ibhulashi noma sokuprakthiza nge umlomo wombhobho efanayo;
• izindlela ezikhethekile zokususa nokugqwala kusuka metal (unamathisele, spray, uketshezi).

Njenganoma iyiphi enye i-nitrous ungqimba kalula neutralized ezonakalisayo acid. Ngakho-ke, leso sidakamizwa iqukethe cishe nganoma iyiphi indlela zokususa nokugqwala kusuka metal.

Icubungula athutha

Le nqubo Kungcono ukusebenzisa ukususa ukugqwala ukubonakaliswa nge esipara kokuba endaweni enkulu. I metal kulokhu pre bahlanza ngokucophelela ngokudlulisa. Khona-ke amabala abomvu ziyasuswa usebenzisa sokuprakthiza eline ibhulashi noma isondo athile.

Le nqubo yokwelapha kumele kwenziwe ngaphambi metal okumsulwa. Ezindaweni akude ukuthomba isuswe ngumuntu nazhdachki.

Ukususwa nokuthenga chemical izindlela

Izitolo ukwakhiwa senzelwe wokuhlanza izinsimbi ngokumelene nokugqwala, ingasetshenziswa ezimweni eziningi ezahlukahlukene. Nokho, ngokuvamile zonke izinhlobo nokunamathisela liquid ukuthola uma kunesidingo yokusingatha izinto elincane ukuma eziyinkimbinkimbi. Uma usebenzisa amathuluzi anjenge sokuzivivinya, futhi isicelo kumele kube njengoba ngokucophelela. Njengoba zonke ayinhlama anticorrosion futhi uketshezi aqukethe acid, ukugwema kubo ku yomzimba kuyinto engathandeki kakhulu.

Lapho efeza umsebenzi wokulungisa kanye nokwakhiwa kwemisebenzi kufanele futhi usebenzise noma iyiphi i-ejenti zamakhemikhali zokususa nokugqwala kusuka metal. Ngaphambi yokudweba zonke izinhlobo emgwaqweni futhi itholakala ezindaweni ezinomswakama kwezakhiwo aphathwa kufanele kube impoqo. Sebenzisa ezinengilazi ngaphandle pre-yokuhlanza evele kuleli cala zimane lutho. Ngisho ngempela qhubeka ngaphansi upende namachibi inqubo.

Indlela electrochemical

Le nqubo kufanelekile yokuhlanza cishe kunoma iyiphi izinto eziyinsimbi. Ukuze kususwe nokugqwala ngale ndlela kudingeka umthombo samanje, futhi i-electrolyte. Kugcine batheleka sifakwe ebhakedeni. Kukhona futhi abeke isihloko ezidinga ukwelashwa. Okulandelayo, electrolyte ixhunyiwe oxhumana omuhle kanye metal - ezimbi (ukuze akusho mbeni ketshezi).

Ngemva voltage in the ibhakede iqala ukusabela electrochemical, umphumela lapho siba oxide legatsha futhi sebethule yayo phansi.

Indlela ukuhlanza nokugqwala kusuka umzimba imoto

izindawo Red ezivela metal izingxenye umshini, ehlanzekile indlu kufanele ibe ngokushesha ngangokunokwenzeka. abashayeli abaningi bazi ukuthi khona nokugqwala phezu bodywork imoto inani layo kuyehla mayelana into 2-3. Esikhundleni konakalisa ukugqwala ngokuningiliziwe eqolo.

Ukuhlanzwa izinqubo zomzimba imoto , kukhona eziningana. Ezimweni eziningi, le njongo ke ithengiswe uketshezi oluqinile kanzulu zokususa nokugqwala kusuka metal.

Ngezinye izikhathi umzimba ezilimele ndawo selashwe alulaze orthophosphoric acid. Enye indlela enhle yokusiza abantu bahlukane nazo izindawo abomvu phezu izimoto ukusebenzisa ingxube esekelwe zinc nosawoti. Kulokhu, lisebenzisa inqubo electrochemical ngoba sokuhlanzwa, kodwa yebo, ngaphandle kokusebenzisa bomkhumbi. Ingxube lasetshenziswa isilonda ngendwangu phezu electrode. Ngaphezu kwalokho, umyalo wokugcina ixhunywe ibhethri.

Ukuqhathanisa izindlela ekususeni imoto nokugqwala metal (uthenge)

Zonke izinhlobo ukwakhiwa eklanyelwe ulwe ukugqwala, namuhla emakethe ziningi. Ukuze ekucubunguleni izingxenye ezinkulu imoto - umzimba noma injini, isibonelo, evame ukusetshenziswa izindlela "deoxy". ingxenye yayo oyinhloko i surfactant acid.

Ngaphezu kwalokho, ukubuyekezwa omuhle kakhulu lapho futhi uketshezi "Antirzhavchina NEOMID 570". It angasetshenziswa ukwelapha umzimba noma injini. Dumisani yindlela ekususeni nokugqwala kusuka metal izimoto, phakathi kwezinye izinto, futhi ngenxa yokuthi usebenzisa zingase zihlanzwe hhayi kuphela ukukhanya entsha, kodwa futhi amabala inveterate. Kulo mBhalo it is isetshenziswa ebusweni noma bagxila ewuketshezi, noma alulaze, kodwa izingqimba eziningana. Isigamu sehora ngemva kwengoma ukwelashwa kufanele wageza off ngamanzi.

Ngisho umphumela evelele lapho wokuhlanza izingxenye auto ingatholakala kusetshenziswa ikhambi yasekhaya zokususa nokugqwala kusuka metal "Tsinkar". Ngemva ukwelashwa ngalezi zithako eshiya phezu kuhlanganiswe ifilimu zokuzivikela. Lokho "Tsinkar" namuhla angabhekwa okungcono ukugqwala inhibitor ngenxa metal evele.

Small-chrome izingxenye izimoto zivamise nahlanza usebenzisa-non woketshezi, ukunamathisela ekhethekile. Kuhle kakhulu le njongo, isibonelo, efanelekayo Metall basePoland "Avtosol". Lokhu nokunamathisela sisetshenziswa ku ngendwangu, okwathi ngemva kwalokho nto wagcoba kuze ephelele oxide ukususwa.

Ukuhlanza izitsha

Nganoma iyiphi indlela zokususa nokugqwala kusuka metal imoto ngokuvamile yakhiwa nenani elikhulu kakhulu acid. Ngakho-ke, ukwelapha izinto ezisetshenziswa ekuphileni kwansuku zonke, kubalulekile ukusebenzisa wonke amanye, kwakheka izakhi ezibanga ingozi ngaphezulu. On ukudayiswa namuhla phakathi eziklanyelwe lolu injongo izifutho futhi uketshezi. Abakwazi kalula bahlanza nokucwila steel, i-chrome ekhishini amasethi, izitsha nokunye. D.

zithandwa kakhulu besifazane kuyinto, isibonelo, kusho zokususa nokugqwala kusuka "Adrilan" metal. Ukwahlulela ukubuyekezwa, ukususa amabala oxide kusukela evele ezahlukene ukusetshenziswa yayo kungaba cishe ngaphandle zingaphazamisi. Kulokhu, sebenzisa "Adrilan" bavunyelwe ukuhlanza, hhayi kuphela metal, kodwa evele futhi enamelled. Idumela elihle kakhulu phakathi besifazane futhi usebenzise ezifana converters of nokugqwala, njengoba "Omega-1», AVS Avk futhi Runway.

izindlela Traditional emzabalazweni

Manje ake sibheke ezinye izindlela ngokurhaba ukususa nokugqwala kusuka metal ekhaya ngeke ivumelane engcono. Kulokhu, ngenhlanhla zingasebenzisa amasu ahlukene. Ngakho, ukuze bahlanze steel nensimbi izinto evame ukusetshenziswa kakhulu soda. Kule kufanele wenze slurry ewugqinsi (ngokungeza amanzi) kanye gcoba ubuso bayo. Ngemva cishe isigamu sehora ukusula into ziphathwe esintamo ibhulashi noma ngocingo uvolo yokugeza izitsha.

Ngaphezu soda, ukuhlanza metal evele ngokumelene ukugqwala ingaphinda isetshenziswe:

• Isoso. It isetshenziswa endaweni ethintekile, bese ukusula owomile ebusweni isilonda ngendwangu ehlanzekile.
• Kalamula. Leli thuluzi zisebenzisa kanye isoso.
• A ingxube uviniga nosawoti. Ukusebenzisa slurry enjalo kungaba zisuswe ngisho ngempela nokugqwala amabala ubudala.
• ucwecwe Baking. Idinga ukuba namandla ukuze akuqede ibhola basihlikihle ibala.

Futhi, uma uthanda, ungasebenzisa zamanani aphansi kusho zokususa nokugqwala kusuka metal ekhaya, njengoba exutshwe indawo usawoti yashizi amazambane.

Kwenzeka ukuthi izindawo abomvu avele hhayi kuphela steel esitsheni, kodwa futhi phezu yensimbi yokusakaza. Kulokhu, lo ukwelashwa surface livamise ukusetjenziselwa amafutha zemifino. Khangela, basibekele odongeni inkatho yensimbi pan, bese batheleka yamanzi ngase ngiyibeka phezu komlilo. Ukuze ususe nokugqwala kusuka yensimbi ngokuphelele, abilayo ngokuvamile okuphindaphindiwe kabili.

Indlela yokusingatha amathuluzi

Yokuhlanza izindawo abomvu ngokuvamile kudingeka futhi okulima ahlukahlukene. Futhi-ke, abanikazi abaningi emaxhaphozini izindlu unesithakazelo, lokho kusho zokususa nokugqwala kusuka metal singasetshenziswa kuleli cala?

Kukholakala ukuthi amabhowudu, impintshisi, izimfoloko, ukucisha nokunye. E. engcono elula indlela ukusingatha diesel. Ukuze wenze lokhu, mane nje uthele amafutha kwezinye izikhundla, base bemehlisa amathuluzi. Ngemva kwamahora ambalwa yokusungula athathe, kahle wagcoba ngendwangu futhi ngamanzi.

Ukucubungula izinsimbi non-ayoni

Brass, njengoba steel kusuka ukugqwala is best bahlanza uviniga ingxube (120 g) nosawoti (1 h / l). Slurry ngakho-ke kuyadingeka ukuze ungeze ngofulawa omncane. Ngemuva kwemizuzu engu-30, unama metal isetshenziswa isidingo hashaza ngamanzi afudumele.

Aluminium nokugqwala lula angabacwasi ukuhlanza ngokusebenzisa "Alka-Seltzer." ithebhulethi Kutholiwe ukuncibilikisa emanzini noma isiphi isitsha bese uphonsa ukuba uketshezi abadinga imishanguzo tesifundvo.

Indlela yokuvimbela ukugqwala

Hlanza ezindaweni ezithintekile of nokugqwala on insimbi kungaba ngezindlela eziningi. Uma inqubo uye asikabi babi kakhulu, ukwenza kanjalo kwakungeke kube nzima kakhulu. Nokho, kulula, yebo, ukuvimbela ukubukeka sufaka oxide. Ukuze aphonse Insimbi, steel, i-aluminiyamu nokunye. E. Kwamanzi akusho oxidize, kufanele nigcine izimiso ezimbili ezilula. Gcina lezi zinto zidinga ukuba ome. Ngemva ukusetshenziswa, kungakhathaliseki ukuthi kufanele kahle bahlanza.
