Ukuvikelwa Corrosion: incazelo, izici, imibono kanye nokubuyekeza

Ukuvikelwa izinto ezifweni nokugqwala isilinganiso saziso ngaphambi ukwethulwa kwetakhiwo, izingxenye ngabanye ukusebenza. Kutfutfukiswa ukugqwala ivame metal evele hhayi kuphela, kodwa futhi kubathinta kabi property izinto ezizungezile - plastic noma ukhuni. indlela Ngokuvamile, at the stage of prefabrication akhethiwe ngawo isivikelo esinjalo ngeke abulawe. futhi kungenzeka kwakhiwa igobolondo Anticorrosive endaweni yasekhaya ngokusebenzisa amathuluzi akhethekile.

ulwazi olujwayelekile mayelana rustproofing

Iningi Ukuvikelwa izimali ukugqwala isetshenziswa yendwangu, okuyinto kwakha enamathela amelana ukuthuthukiswa izinqubo ezimbi. Ngokuvamile, ukucutshungulwa enjalo wadalula izihloko kanye nezakhiwo zazo eduze baxhumane umswakama, futhi amakhemikhali inhlabathi. Ngokuvamile, isivikelo ukugqwala kuyinto Amatebhe. Lokho ngaphezu nokuvimbela okufanayo nokugqwala enamathela kungaba ngcono izimfanelo nangokuvikela into futhi, ukuqinisekisa umphumela umsindo ukunciphisa.

naphakathi ngamunye inezingozi zayo isinyathelo futhi abhidlizwa ngesikhathi operation. Lokhu ehilelekile ukunikeza ubuchwepheshe enkulu ekukhethweni kuka-indlela yokwelapha. Ngaphezu kwalokho, Ukuvikelwa ukugqwala kungaba uqobo kube esebenzayo chemical izidakamizwa. Ukuze ngezinto ezihlukahlukene futhi Alloys akhethiwe elihle kunawo kusukela iphuzu Ngenxa imiphumela mutual ezinengilazi zokuzivikela.

Izici izindlela okuvikela nokugqwala

Sebenza nge ingxenye metal ekusebenziseni ezinengilazi zokuzivikela zidinga ukulungiselela kahle. Ngokuvamile, imisebenzi esemqoka ukubhekana nalesi sigaba esithile. Ngaphezu kwalokho, ngokungafani nezinye amasu izinto ukucubungula ukwakha isizinda ukubiya ukuze nokugqwala ngokuvamile kuhilela ukusetshenziswa kwakwakhe ezengeziwe. Ngakho, ngisho nasezimweni eyinkimbinkimbi wakhiwa Ukuvikelwa ukugqwala umphumela ukwahlukanisa kagesi.

Ukusetshenziswa eqondile izinhlobo ezahlukene ukuvikelwa ukugqwala nalo kunqunywa kwenkululeko into target. Uma uhlela ukuba asebenzise i-design ngaphanzi komhlaba, njengoba kunjalo egijima amanzi noma igesi ngezidingo, zokupheka achazwayo ezinengilazi multilayer, futhi nikela sithuthukiswe Ukuvikelwa lokukhanda. Okunye izimfuneko izinto mbeni umoya namanzi. Kulokhu, ukunakwa ikhokhelwa ukuvikela ukwahlukanisa yokulwa umswakama, umusi kanye frost. Kuze kube yimanje, i-izingoma kunezelwa izithasiselo ezifanele futhi plasticizers.

Ziningi izindlela esingazisebenzisa

Indlela yendabuko ukuvikela metal kusuka ukugqwala kubhekwa isicelo of ezinengilazi, ekuvimbeleni inqubo rusting. Kungenzeka amalungiselelo ezivamile izingoma zokuhlobisa ephinde ukwenza umsebenzi ngenxa yobuhle. izindlela Okuningi eyinkimbinkimbi yokuvikela - kuyinto ukwelashwa ezishisayo kanye doping. Kulezi zindlela, indaba ngokwayo siyashintsha isakhiwo ungqimba engenhla.

Ngokwesibonelo, alloying metal Alloys ivumela ukudluliswa kusuka asebenzayo esimweni yekwentiwa. Ngakho-ke, izinto Ukuvikelwa ukugqwala ngokwemvelo kwakhiwa ifilimu, okuyinto isithiyo phambi rusting ku isizinda ukwelashwa electrochemical. Le ndlela yokuthi hhayi kuphela isebenza ngempumelelo nensimbi kalula buqeda izinsimbi, kodwa futhi ngensimbi engagqwali izinto steel okungase zikhubazekile ezindaweni onakalisayo.

Uphenyo ukuvikelwa upende of izinsimbi

Lena yindlela ethandwa kakhulu ukuvikela metal kusuka ukugqwala. Inani layo ngoba ukuyikhokhela, a ukusebenza kuqhathaniswa okusezingeni eliphezulu nakalula. Noma kunjalo, ukuvikela ukugqwala eside upende kuzibonakalisa hhayi indlela engcono kakhulu. Njengoba abasebenzisi iphathwa kule design imfashini, ukubala on ephelele ngabodwa umsebenzi-akhawunti kungekho isikhathi esingaphezu kweminyaka engamashumi 7-8. Ngaphezu kwalokho, enamathela has ukuvuselela njalo futhi abuyisele ama-yendwangu target.

Kunezinye nemibi eziphawula abasebenzisi anti-ukugqwala upende ukwakhiwa. Ngokwesibonelo, kwezithibelo ukusetshenziswa. inketho okunjalo akudingekile ukwandisa ipayipi wenziwe ngaphansi kwamanzi noma phansi. Uma ukuvikelwa ukugqwala kufanele ube neminyaka engaphezu kwengu-10 ngaphandle isibuyekezo, kunengqondo ukusebenzisa ezinye izindlela.

Uphenyo Electroplating

Le ndlela kusebenza futhi bendabuko. Ubizwa kaningi lisetshenziswe umkhakha futhi embonini yezokwakha. Ngokusho kochwepheshe abaningi, iyona engcono kunazo inketho kwaqanjwa ukucutshungulwa, adizayinelwe ukusebenza yesikhathi eside. It ngempumelelo ivikela metal kusuka ukugqwala nezinye izinqubo nokucekelwa. Kodwa kufanele sikhumbule futhi ukuthi ukuvikelwa ukugqwala izakhiwo by Electroplating kuyabiza, kudinga a professional approach ukuqaliswa kanye lulodwa operation isikhathi.

Empeleni, le ndlela yokukhuluma galvanizing, nakho kufaka ukulungisa owandulelayo ebusweni metal. Amalungu waphawula ubunkimbinkimbi ehilelekile ekwenzeni sandblasting kanye etching. Endaweni yasekhaya ukusebenzisa le ndlela ngeke usebenze. Nakuba Plating is NEMPUMELELO okuningi ke kuzibonakalisa ukusebenza kuka upende amathuluzi.

Izibuyekezo yokuvikela ezishisayo

Lena ngenye indlela sokukhomba sokulungiswa isakhiwo impahla bonyana batshidze molecule. Thermal Ukuvikelwa ukugqwala of amapayipi, ngokwesibonelo, ivumela nje kuphela ukuvikela metal kusuka ukugqwala, kodwa futhi ukususa voltage design, uma itholakala ngomshoshaphansi.

Ngokwe-abasebenzisi yaleli su, liveza izindawo okusezingeni eliphezulu nesivikelo saKhe izimo zokusebenza ezinzima ngendlela exakile. Nokho, ukucutshungulwa ezinjalo ezingase zithathwe kuphela ngokusebenzisa imishini ekhethekile ezimbonini. Kuhhonela kokudubula chamber kanye izinqubo cryogenic iyabiza, echaza ukuthandwa eliphansi ngalesi sivikelo.
