Ubhidekile malunga neStructure Anti-Corrosion? Iinketho ezisemgangathweni kunye neziKhokelo zokuKhetha

Isakhiwo sentsimbiI-anti-corrosion ibalulekile ekwandiseni ubomi benkonzo yezakhiwo. Izikimu zokukhusela umhlwa ziyahluka ngokwendalo eyahlukeneyo kunye neendawo zenkonzo. Uphononongo olubanzi luya kwenziwa kumalungiselelo omphezulu kunye nemilinganiselo yokunqanda ukuthotywa kweendleko zokuqala zokwakha kunye nokwandisa ubomi besakhiwo.

Zonke iintlobo zezakhiwo zixhomekeke kwimpembelelo yeendawo ezinobungozi, ezihlelwe kwiindidi ezahlukeneyo zokubola ngokusekelwe kwiimeko zenkonzo.

Iindlela ezahlukeneyo zokunqanda umhlwa ziya kukhethwa ukuze zimelane nemo engqongileyo enomhlwa. Kungakhathaliseki ukuba yiyiphi isisombululo esamkelweyo, ukulungiswa komphezulu kubeka isiseko sokukhusela i-corrosion kwaye inquma ukuba i-coating yokukhusela inokwenza njengoko kuyilwe. Ngokuqhelekileyo, ukutshatyalaliswa kwesanti okanye ukudubula kusetyenziselwa ukukhutshwa komhlwa kweeworkshops zesakhiwo sensimbi, kunye nenqanaba lokucoceka elincinci le-Sa2.5, elichazwe njengokucoca ngokucokisekileyo kakhulu. Ukongezelela, umgangatho wokuqala wokugqwala we-substrates wensimbi uya kuqwalaselwa. Imathiriyeli ekrwada engenako ukukhawulelana nomgangatho ofunekayo nasemva kokuba unyango olungaphezulu luya kutshintshwa okanye ilahlwe.

Ekugqityweni kokulungiswa komphezulu, inyathelo elilandelayo kukukhetha inkqubo yokunqanda ukubola. Ukutshiza ipeyinti kunye ne-hot-dip galvanizing zizisombululo ezimbini eziphambili. Ngaphandle koko, iindlela ezininzi ezivunyiweyo zokulwa nomhlwa zamkelwa ngokubanzi kwiiprojekthi ezisebenzayo: 

(1) I-Weathering steel ilungisa imiba ye-corrosion, esebenza kwinxalenye yangaphandleizakhiwo zentsimbi, kodwa kunye neentsilelo zeendleko eziphezulu kunye nenkangeleko embi. 

(2) Ukutshiza nge-Thermal (i-aluminiyam yokutshiza / ukutshiza i-zinc) ihambisa umsebenzi olinganayo ne-hot-dip galvanizing kwaye ibonakalisa ukuguquguquka okungcono kwimilinganiselo yecandelo, ilungele amalungu entsimbi ekhethekileyo kunye neendawo ezinobungozi kakhulu.

(3) Ukukhuselwa kweCathodic kuxhomekeke kwimigaqo ye-electrochemical anti-corrosion, esetyenziswa kakhulu kwizakhiwo zetsimbi ezifakwe ngaphantsi kwamanzi okanye zingcwatywe phantsi komhlaba. Iinkqubo ezintsha zokukhusela ezihlanganisiweyo zisebenza njengezinye iindlela ezizezinye ngaphaya kwezisombululo eziqhelekileyo, ezifana ne-anti-corrosion edibeneyo kunye neengubo ezinokumelana nomlilo kunye ne-graphene enzima yokukhusela i-corrosion.

Multi-Layer Spray Coating System

Inkqubo yokutshiza i-anti-corrosion system yakha i-multi-layer yokukhusela i-multi-layer kwi-party surfaces enemisebenzi ehlukeneyo, eyona nto ihlulwe ibe ngamacandelo amathathu: i-primer, i-coat ephakathi kunye ne-topcoat. I-primer isebenzela ukunamathela kunye nokukhuselwa komhlwa. I-epoxy zinc-rich primer enomxholo we-zinc engekho ngaphantsi kwe-70% isetyenziswa ngokuqhelekileyo. I-Inorganic zinc-rich primer yenye enye, kodwa ubukhulu bayo befilimu eyomileyo bufuna ulawulo olungqongqo. I-epoxy micaceous iron oxide intermediate coat ifakwa kumaleko aphakathi, kunye ne-aliphatic polyurethane topcoat okanye ifluorocarbon topcoat yamkelwa njengedyasi yokugqiba. Zonke iinkqubo zenkqubo yokutshiza ziya kugqitywa kumzi-mveliso ofanayo ukuze kuqinisekiswe umsebenzi ozinzileyo kunye nokusebenza okuthembekileyo kokuchasana nomhlwa.

Ukugalela

I-galvanizing ihlulwe ibe yi-galvanizing eshushu-dip kunye ne-electro-galvanizing (i-galvanizing eqhelekileyo). I-Hot-dip galvanizing (igama elipheleleyo: i-hot-dip galvanization) yenza ukugquma kwe-zinc ekhuselayo ngokuntywilisela intsimbi kwibhafu ye-zinc etyhidiweyo. Ibonisa umaleko oshinyeneyo we-zinc ukusuka kwi-65μm ukuya kwi-200μm. Ngokumelana nokugqwesa okugqwesileyo, ubomi benkonzo ende, ukubambelela ngokuqinileyo kunye nenkqubo elula, inobunewunewu bembonakalo ephakathi kwaye ifanelekile kumacandelo amakhulu olwakhiwo. Electro-galvanizing deposits zinc coating ngokusekelwe kumgaqo electrolysis. I-zinc layer yayo incinci, ngokuqhelekileyo i-20μm ukuya kwi-30μm. Iqhayisa ngesiphumo esihle sokuhombisa kodwa inkqubo yemveliso entsonkothileyo, esebenzayo kwiindawo ezincinci ezichanekileyo okanye izakhiwo ezifuna ukhuseleko oluchasene nokubola.

Ukhuseleko lomhlwa kwiiiworkshops zentsimbiiqala ngokuqinisekisa udidi lwe-corrosion yendawo yokusebenza, ukugqiba ukulungiswa komphezulu ofanelekileyo kunye nokukhetha isisombululo esifanelekileyo sokuchasana ne-corrosion. Njengomenzi wesakhiwo sentsimbi yobuchwephesha, i-EHSS inobunzulu obunzulu bazo zonke iinkqubo ezichasene ne-corrosion kwaye inokukunceda ekukhetheni iindleko zokonga kunye neenkqubo zokukhusela i-corrosion ephezulu.
