Indlela ukususa nokugqwala kusuka metal ekhaya

Ngendlu wabheka ezikhangayo futhi njalo ukudala umkhathi samaholide, it ngokuphelele konke kumelwe sibe bahle. ukunakekelwa ngokukhethekile liyadingeka ukuze anakekele Ukuvikelwa zokuhlobisa kanye eliphezulu izakhi ngensimbi. upende Modern ngokuba metal kuyosiza kule. Ngakho, uma sizibuza ukuthi ukususa nokugqwala kusuka metal, khona-ke konke kuzoba lolu daba.

Yini idili?

Ekuphileni kwethu kwansuku zonke futhi ukwakhiwa yesimanje isebenzisa omningi ezakhiwe ngensimbi, okumele avikelwe ngokucophelela emiphumeleni izici kwezemvelo okunomthelela omubi kakhulu, okuholela ukugqwala - nokucekelwa metal kubangelwa izinqubo electrochemical namakhemikhali. Ngokuhamba kwesikhathi, ukugqwala kubangela ukwehla kwe-amandla imikhiqizo metal nokubhujiswa kwabo, kancane kancane balahlekelwa ukubukeka kwabo futhi ulahlekelwe izinga yabo kwesakhiwo. Corrosion izinqubo zenzeka ngamazinga angefani kuye ngokuthi izimo umkhiqizo isetshenziswa ngaphansi kwazo. Njengoba aluqede ngokuphelele imiphumela asemkhathini isakhiwo metal cishe kungenakwenzeka, ngakho ongaphambili inkinga yokuvikela. Kuphakathi kukhona umbuzo: kanjani ukususa nokugqwala kusuka metal?

Indlela elula yokuphuma

Ngo umkhuba, ngokuphindiwe sifakazelwe ukuthi yimuphi izakhiwo metal indlela elula ukuvikela ngokulisebenzisa uyinki okhethekile. Uma kuqhathaniswa nezinye izinto izinhlobo ezinengilazi okuvikela upende has eziningi eziwusizo: ukudlala futhi okusezingeni eliphezulu sebethule isilinganiso, ikhono ukwakha enamathela umbala oyifunayo. Izimo zethu zihluke kakhulu iphuzu elibalulekile siphathelene kungenzeka kucutshungulwa isizinda takhiwo ukumisa eziyinkimbinkimbi futhi usayizi esikhulu. Ngokusetshenziswa upende yesimanje kanye namathuluzi, ungakwazi kwamandla silondoloze imikhiqizo metal zisesimweni esihle. Esimeni semakhaya ukunakekelwa kahle ungakwazi ukubala iminyaka yesevisi.

Nokho, noma kunjalo, ngaphambi yokudweba kuyadingeka ukuqeda imithelela ukugqwala izinqubo, okungase uqale kahle. Ngakho-ke kuphakamisa umbuzo wokuthi indlela ukususa nokugqwala kusuka metal?

substrate ukulungiselela

Njengoba ebusweni metal edingekayo ukususa upende omdala, i-adhesion upende besiyikhwalithi kangcono. In the isinyathelo esilandelayo udinga ukuhlanza ebusweni ezingcolisa ezihlukahlukene, kanye nokugqwala, okungase sezivele ziyavela lapho. Inqubo uhlanzekile kungaba amakhemikhali, ezishisayo noma mechanical. Uma uqhubeka ukhulume kanjani ukususa nokugqwala kusuka metal ekhaya, kufanele sicabangele ngayinye yalezi zinkulumo.

Indlela yokuqala kuhilela ukusetshenziswa ane-alikhali yokuhlanza izingoma noma kumakhemikhali awuketshezi okusebenzayo compounds ahlukahlukene organic. Yilokho kuyokusiza ukuba sinqume ukuthi ukususa nokugqwala kusuka metal esebenzisa amakhemikhali. Ngu athutha bamukele ukuqonda Luhambo materials olwalwenza, kungaba ingxenyenamba, esihlabathini, ingxube amanzi nenhlabathi, lokukhuhla , nezinye, amathuluzi akhethekile - grinders, emabhulashini, imimese nokunye. Ngu le ndlela-ke kutholakala iyunifomu bahlanza ebusweni maholoholo ukuthi singase sinyuse degree of adhesion kuya ifilimu upende.

I ezishisayo Luhambo indlela kuhilela hot air isibhamu noma ilangabi ithoshi acetylene.

ukucutshungulwa

Ngakho lapho sekumcacela kuwe kanjani ukususa nokugqwala kusuka metal, sekuyisikhathi ukhulume olunye ukwelashwa surface. Ngemva wokuhlanza, kufanele isethwe le nqubo elandelayo wokulungiselela - priming futhi Shpatlevanie. Ukusebenza lokuqala wenziwa ukwakha isibopho ngokwanele phakathi komhlaba zaveza kwezinye izingqimba upende. Priming futhi inikeza ngezinga eliphezulu ukumelana ukugqwala metal ligamanxa ikhule ezimbotsheni nezinye zamehlo. Ngakho, uma kakade baqonde indlela ukususa nokugqwala kusuka metal phambi imidwebo, okungukuthi ukuthi priming inqubo elilandelayo ngemuva nje nakacedza umsebenti ku wokuhlanza ebusweni. It lisetshenziswa ebusweni ungqimba ezondile isakhiwo ekhethekile ebizwa ngokuthi i-primer.

zinhlobo ukwakheka

Ngakho, uma uyazibuza kanjani ukususa nokugqwala ensimbini we imoto, kwenziwa ukuthi kukhona Rust, ngempela elula ngendlela yokuhlakanipha. Lokhu kungenxa ukungabi nakwenzeka kwento ukususwa ephelele imikhiqizo ukugqwala abobunjwa eyinkimbinkimbi noma ibe yinkimbinkimbi. Ukusebenzisa ukwakhiwa okunjalo kungenzeka emva ukususwa mechanical ungqimba phezulu nokugqwala olubheka alengayo kakhulu. Njengengxenye yalezi kwenziwa kukhona modifiers ethize ukuguqula oxide yensimbi kusimo esisha - adhesion Friend kwamanzi metal. compounds okunjalo ingangqubuzani ukumelana ukugqwala bese enamathela adhesion. Ngokuvamile modifiers kukhona amagama ahlobene of wali band acid, kanye ezinye tannins.

Esigabeni esilandelayo

Ngemva kokuphothulwa isikhathi priming iza isinyathelo esilandelayo - shpatlevanija. Le ndlela yakhelwe imifantu uphawu, ebusweni ukuqondanisa, lidlulisele homogeneity s. Putty - ingxube ehlanganisa plasticizer, yamathebhu, isibopho kanye izithasiselo ezithile.

Shpatlevanie ingxube lingathengiswa ku ezomile noma ngomumo-kuya-sidle fomu. Ngokuvamile ekhiqizwa isicelo putty ukuze ebusweni by spatula futhi phambili yokululama yayo. Lapho base esehlanjululwe ngokuphelele, primed kanye isivalo, usungaqala fafaza upende ukuthi uqedela.

phezu upende ebusweni metal singasetshenziswa ngu emabhulashini, ezinamasondo noma izifutho. Isibalo enamathela izingqimba incike opacity yayo. Ngakho manje wena nje kuphela ukwazi ukuthi ukususa nokugqwala kusuka metal, kodwa futhi ukuthi kufanele uzivikele kanjani kuye, sezinkinga ezinjalo akazange kuphakama esikhathini esizayo.
