Kodi Mukusokonezedwa ndi Chitsulo Chotsutsana ndi Corrosion? Zosankha Zokhazikika & Malangizo Osankha

Kapangidwe kachitsuloanti-corrosion ndiyofunikira kuti muwonjezere moyo wautumiki wa nyumba. Njira zodzitetezera ku dzimbiri zimasiyana malinga ndi malo osiyanasiyana achilengedwe komanso ntchito. Kuunikira mwatsatanetsatane kudzachitidwa pokonzekera pamwamba ndi njira zotsutsana ndi dzimbiri kuti achepetse ndalama zoyamba zomanga ndikutalikitsa moyo wa nyumbayo.

Mitundu yonse ya nyumba zimakhudzidwa ndi kukhudzidwa kwa malo owononga, omwe amagawidwa m'magulu osiyanasiyana a dzimbiri kutengera momwe amagwirira ntchito.

Mitundu yosiyanasiyana yolimbana ndi dzimbiri idzasankhidwa kuti ithane ndi madera osiyanasiyana owononga. Ziribe kanthu kuti njira yothetsera vutoli ndi yotani, kukonzekera pamwamba kumayala maziko a chitetezo cha dzimbiri ndikuwonetsetsa ngati zokutira zotetezazo zingakhoze kuchita monga momwe zinapangidwira. Nthawi zambiri, kuphulika kwa mchenga kapena kuphulitsa kuwombera kumagwiritsidwa ntchito pochotsa dzimbiri pamisonkhano yamapangidwe azitsulo, ndi ukhondo wocheperako wa Sa2.5, womwe umatanthauzidwa ngati kuyeretsa mozama kwambiri. Kuphatikiza apo, gawo loyambirira la dzimbiri la magawo azitsulo liyenera kuganiziridwa. Zida zopangira zomwe sizingakwaniritse mulingo wofunikira ngakhale pambuyo pa chithandizo chapamwamba zidzasinthidwa kapena kutayidwa.

Mukamaliza kukonzekera pamwamba, chotsatira ndicho kusankha anti-corrosion system. Kupopera mbewu mankhwalawa ndi kuthira madzi otentha ndi njira ziwiri zazikulu zothetsera. Kupatula apo, njira zingapo zotsimikizirika zolimbana ndi dzimbiri zimatengedwa kwambiri pama projekiti othandiza: 

(1) Chitsulo chanyengo chimathetsa vuto la dzimbiri, lomwe limagwira ntchito panjazitsulo zomangamanga, komabe ndi zovuta za kukwera mtengo ndi maonekedwe oipa. 

(2) Kupopera mbewu kwa matenthedwe (kupopera mankhwala kwa aluminiyamu / kupopera zinki) kumapereka magwiridwe antchito ofanana ndi kuthirira kotentha komanso kumathandizira kusinthasintha kwa magawo, abwino kwa mamembala apadera achitsulo komanso malo owononga kwambiri.

(3) Chitetezo cha Cathodic chimadalira mfundo za electrochemical anti-corrosion, zomwe zimagwiritsidwa ntchito pazitsulo zazitsulo zomizidwa pansi pa madzi kapena zokwiriridwa pansi. Njira zodzitetezera zopangira zinthu zatsopano zimakhala ngati njira zina zopitilira njira zanthawi zonse, monga zokutira zothana ndi dzimbiri komanso zokutira zosagwira moto ndi zokutira za graphene heavy-duty anti-corrosion.

Multi-Layer Spray Coating System

Dongosolo la kupopera mbewu mankhwalawa anti-corrosion dongosolo lazitsulo limamanga zokutira zodzitchinjiriza zamitundu yambiri pazigawo zokhala ndi ntchito zosiyanitsidwa, zomwe zimagawika m'magulu atatu: primer, malaya apakati ndi topcoat. The primer imagwira ntchito yomatira komanso kuteteza dzimbiri. Epoxy zinc primer yokhala ndi zinc zosachepera 70% imagwiritsidwa ntchito kwambiri. Inorganic zinc wolemera primer ndi njira ina, koma youma filimu makulidwe amafuna kulamulira kwambiri. Chovala chapakati cha epoxy micaceous iron oxide chimayikidwa pakatikati, ndipo aliphatic polyurethane topcoat kapena fluorocarbon topcoat amatengedwa ngati malaya omaliza. Njira zonse zopopera mbewu mankhwalawa ziyenera kumalizidwa mufakitale imodzi kuti zitsimikizire kukhazikika kokhazikika komanso magwiridwe antchito odalirika oletsa dzimbiri.

Galvanizing imagawidwa mu kutentha-kuviika galvanizing ndi electro-galvanizing (wamba galvanizing). Dip galvanizing (dzina lonse: galvanization yotentha) imapanga zokutira zoteteza za zinki pomiza chitsulo mu bafa losungunuka la zinki. Imakhala ndi wosanjikiza wa zinc kuyambira 65μm mpaka 200μm. Ndi kukana kwamphamvu kwa dzimbiri, moyo wautali wautumiki, kumamatira kolimba komanso njira yosavuta, imakhala ndi vuto la mawonekedwe apakati ndipo ndi yoyenera pazigawo zazikuluzikulu zamapangidwe. Electro-galvanizing deposits zinki zokutira kutengera mfundo ya electrolysis. Zinc wosanjikiza wake ndi woonda, nthawi zambiri 20μm mpaka 30μm. Imakhala ndi zokongoletsa zabwino koma zovuta kupanga, zomwe zimagwira ntchito pazigawo zing'onozing'ono zolondola kapena zomangira zomwe zimafunikira chitetezo cha anti-corrosion.

Chitetezo cha corrosion kwazitsulo kapangidwe misonkhanoimayamba ndikutsimikizira gulu la dzimbiri la malo ogwirira ntchito, kumaliza kukonzekera koyenera pamwamba ndikusankha njira yoyenera yolimbana ndi dzimbiri. Monga katswiri wopanga zitsulo, EHSS ili ndi luso lakuya la njira zonse zotsutsana ndi dzimbiri ndipo ikhoza kukuthandizani posankha njira zochepetsera komanso zoteteza kwambiri ku dzimbiri.
