Ikhambi elingcono kakhulu le nokugqwala on metal: i Uhlolojikelele, izici zohlelo lokusebenza, abakhiqizi kanye nokubuyekeza

Corrosion metal - inqubo yamakhemikhali, eletha eziningi izinkinga, ngoba nokugqwala kungase kuvele iyiphi indawo metal. Indlela yokubhekana naso, futhi kungakhathaliseki ukuthi kukhona ikhambi kuhle nokugqwala on metal? Zama ukuqonda izimbangela nemiphumela.

Yiziphi izindlela?

Lapho ukugqwala we ebusweni metal uqala oxidize whereupon kokubhujiswa kwalo kwenzeka. Hhayi ukuqaphela kulezi zinkanyezi akunakwenzeka, njengoba ebusweni embozwe ngokushesha izindawo konsundu. Ungazama ukubhekana nokugqwala athutha, ie ngu ukugaya endaweni ethintekile ngosizo lamadiski ekhethekile noma lokukhuhla. Yiqiniso, lokhu akulona kuyithuluzi eliphumelela kakhulu ngokumelene nokugqwala on metal, futhi nge nengcindezi enamandla kungalimaza endaweni ngayo. Yingakho ochwepheshe ukweluleka ukusebenzisa chemical compounds akusiza ukuthi balahle nkinga, ekuvimbeleni ivela khona kungenzeka esikhathini esizayo.

izindlela amakhemikhali

Indlela ephumelela kunazo ukubhekana nokugqwala - zisebenzisa ezihlukahlukene zamakhemikhali ukuthi babhekane ngokuphumelelayo ngisho kanzima ukuze afinyelele izindawo umzimba imoto noma ezinye ebusweni metal. Noma yimuphi esebenzisa nokugqwala phezu kwensimbi sisetshenziswa thize:

• kuqala degreased ebusweni;
• kwenziwe yayo ukucutshungulwa ekhethekile izakhiwo;
• ebusweni is wageza izikhathi eziningana;
• kwenziwe izinga omiswe.

Sisebenzisa Converter nokugqwala

Omunye ethandwa kakhulu imishini ekhethekile angabhekana ukugqwala metal - lokhu Converter. Kuyinto kwakwakhe oguqula imikhiqizo ukugqwala e ifilimu zokuzivikela, okubonakala phezu ukuphathwa ngayo has amandla okuhle. Ngokusho ukubuyekezwa, converters ngokwanele umnotho futhi ezihamba kahle nangokuthula. Ngaphezu kwalokho, zingabantu elula, njengoba zikhishwa ngesimo ukumiswa, emulsions noma izixazululo.

ngezimpawu ezinjalo ezazisetshenziswa nokugqwala on enhle metal ngoba kucutshungulwa isizinda izakhiwo kwanoma yiluphi uhlobo, kodwa ngaphansi kombandela owodwa - nokugqwala ungqimba akufanele uzoba mkhulu microns angaphezu kwangu-100. Baningi Izibuyekezo ezinhle mayelana omoya, okuncike kukhona izinto ifilimu ukwakha. Ngaphezu kwalokho, e Ukwakheka kwabo kukhona inhibitors, zombala, biocides, okuyinto ndawonye ukwandisa esivikelo enamathela izici. Ukusebenza kwale izingoma wenziwa ebusweni kuphela walungisa ngokucophelela nge powdery prepurified futhi luyimbudumbudu nokugqwala izingqimba engenhla.

"Tsinkar"

ithuluzi elihle kakhulu ukuba ulwe nokugqwala, ngokubona labo wabhekana inkinga ka ukugqwala komzimba yemoto. Ezicashile "Tsinkarya" ayizakhi esekelwe zinc kanye manganese. Ukusebenzisa ithuluzi nokugqwala on metal, ungakha enamathela ovikelayo phezu impahla esebenzayo. Lokhu ukulungiselela kuyahluka nomthelela ukusebenza ngoba Ukwakheka olinganiselayo. Njengoba abasebenzisi ethi, "Tsinkar" Kulula ukuba sibhekane ngokuphumelelayo ukucutshungulwa zonke evele lensimbi kuyo okudingekile ukususa umonakalo ukugqwala futhi abavikele emiphumeleni nesimo sezulu. Phakathi izinzuzo zikukhombisa kalula ukusebenza ukwakheka, ukuguqulwa nokugqwala, okungase ngisho ukupenda. Phakathi nemiphumela ethile engathandeki embalwa edlule, baningi gxila izindleko ezeqile, ubuthi kanye nesidingo umsebenzi olunembile.

kwenziwa

Libuye libe yindlela ethandwayo ka nokugqwala chemical ku metal. Ukuze ekwelapheni metal evele, ungasebenzisa omningi kwenziwa. Zingaba phosphating, passivating, nangokuvikela, futhi oguqula projection. Phakathi ethandwa kakhulu phakathi abathengi izingoma yilezi ezilandelayo:

1. EVA 0112 (TU 6-10-1234-79). Lokhu Ukwakheka primer yakhiwa wali band acid, esebenza kahle, ikakhulukazi uma sisetshenziswa ndawonye zaveza yayo nge resin epoxy e kwengoma. Ukuze uthuthukise ukusebenza ukwakheka, ungakwazi ukwengeza benzidine noma barium yombala carbonate.
2. EP-0180 (TU 6-10-1658-82). Lokhu primer ilungele ukusetshenziswa ezindaweni lapho ukugqwala kuyinto engalingani. Njengoba abasebenzisi, kwakhiwa uma usebenzisa zithako is phezu ifilimu okuyinto ingaba njengesihluthulelo enamathela self-ultraviolet.
3. EVA-01, ISG (TU 81-05-121-79). Lokhu Ukwakheka is ithunyelwa inombolo enkulu zokuguqulwa, ngamunye ephethe laqanjwa ekhethekile. Ngakho, EVA-07, ISG olumelana umswakama kanye izici zokwakheka komuntu, futhi EVA-016-ISG anezakhi eliyingqayizivele zokuzivikela.
4. Umlungisi MS-0152 sakhiwe fillers ahlukahlukene, zombala, kumakhemikhali awuketshezi. Lena Ikhambi elingcono kakhulu le ukugqwala phezu kwensimbi, engasetshenziswa ngaphansi kwamazinga okushisa aphansi. Ngokwe-nokubuyekezwa, lawa iyindlela enhle ukusetshenziswa self, ngoba ziyasiza futhi uyisithelo esiyisimanga.

Izici isicelo

Nganoma iyiphi indlela uyakwazi ukulondoloza ebusweni metal kusuka ukugqwala kwakufanele sisetshenziswe ngokufanele. Ukuze wenze lokhu, kudingeka uqale kahle ukuhlanza ebusweni kusukela izintuli nokungcola. Uma kusetshenzisiwe ungene Converter ebusweni nokugqwala usebenzisa ibhulashi noma isifutho. Manje kudingeka ulinde kuze sesomile - ekamelweni lokushisa, kuthatha amahora ambalwa. Ngemuva omiswe kufanele ahlaziye endaweni efanele futhi, uma kunesidingo, ukucubungula kabusha Converter yayo.

Indlela ukususa nokugqwala kusuka emotweni?

Ezindaweni eziningi ukugqwala zenzeka emzimbeni imoto. Abakwazi ukuhamba ngoba indawo ukunqotshwa nokugqwala luyokhula kuphela, futhi kusukela iphuzu yobuhle buka, lokhu akulona ikhambi esifanele. Yingakho abaningi uzama ukulondoloza imoto yakho usebenzisa ithuluzi obalulekile kusuka ngomhla ka nokugqwala on metal. Auto emva ukwelashwa okunjalo kungase uthole ngisho the look wokuqala, ikakhulukazi uma ukhetha ngokuhlakanipha izingoma for Umdwebo okwalandela.

Okuchaza ungakwazi enyula bonke khondo of ukugqwala, siye echazwe ngenhla. Into esemqoka - ukuthobela imithetho yokuphepha. Futhi kuhlanganisa nokusetshenziswa amagilavu, buso kanye izibuko, izinga okusezingeni amboze kwemoto, ngakho-ke wasala iminonjana converters futhi kwenziwa. Yiqiniso, ungazama ukubhekana endaweni ethintekile nje umkhiqizo - uviniga, baking soda, kalamula, kodwa lezi zindlela ungasindisi ekhaya kusuka kabusha namachibi.

Ngakho-ke Kungcono ukuthenga ithuluzi ekhethekile zokususa nokugqwala kusuka metal ukuze ubhekane ngokuphumelelayo nalesi umonakalo ngokuyimpumelelo. Okungcono nakakhulu, zisebenze amasevisi ezikhethekile lapho lo msebenzi ngeke ukubhekana kangcono ngisho.
