Munguva yakareba-nzvimbo dzekunze dzinoshanda, kunyanya pasi pemamiriro ezvinhu akaoma semunyu womugungwa, kusvibiswa kweindasitiri, kunaya kweasidhi, tembiricha yakakwira uye hunyoro, uye kutonhora kwakadzikama-kunonyungudika, majoko ejoko anowanzoita ngura, kuonda, kuonda, kutsemuka, uye kunyange kutsemuka, zvinokanganisa zvakananga kuchengetedzeka kwemagetsi, uye kuchengetedzeka kwehupenyu hwetambo. Naizvozvo, tinosarudza majoko anoshingirira mukuora, anogona kuramba asina ngura-asina{4}}asina kukundikana-mahara, uye -akatyoka{7}}asina makore 30 kusvika 50 pasi pemhoteredzo inotyisa. Kusaita ngura hakungokonzerwi nekuvharika kwekuvharika, asi kuti igadziriro yakakwana ye{11}}matanho ekuora zvichienderana nesainzi yezvekushandisa, misimboti yemagetsi, tekinoroji yeinjiniya, uye magadzirirwo akakwenenzverwa. Kusaora kwayo kunobva kunzira ina: dziviriro, cathodic sacrificial protection, passivation self-healing protection, uye optimized structural anti{14}}corrosion. Mahwendefa ejoko anoiswa pamhepo yakashama kwenguva yakareba, achitarisana nezvinhu zvinoparadza zvakawanda, zvinosanganisira kupfapfaidza kwemunyu, kukoromoka kwemaindasitiri, kunyorova, kukwira bhasikoro, ultraviolet mwaranzi, uye jecha neguruva abrasion. Pasina marata ejoko asingadziviriri, kugadzikiswa kunodiwa panguva-kushandiswa kwenguva refu, zvichiwedzera mari yekushandisa.
Kugadzirisa kugona kunowanzo chiyero chekuyera simba rose remutengesi wejoko risingaparare uye chinhu chakakosha chinotariswa nevashandisi vekunze pakusarudza shamwari. Kubva pamaonero echigadzirwa, mahwendefa ejoko anoratidza dhizaini yakapusa, inochinjika yekuumba maitiro, inodzoreka yekugadzira kutenderera, uye yakakwirira kusarudzwa, inobvumira kugadzirwa kwakagadziridzwa kunoenderana nedhirowa yemushandisi, zviyero, uye mamiriro ekushanda.
Zvimiro zvezvimiro ndizvo zvinogara zvichigadziriswa nevashandisi vekumhiri kwemakungwa, zvichinyatso tarisa kana ndiro yejoko isingadziviriri inogona kuiswa zvakanaka, ingave kugovera kwekushushikana kune musoro, uye kana ichienderana nemasystem aripo. Kugadzirisa kunogoneka kune chimiro, kupatsanura gomba, dhayamita yegomba, ukobvu hweplate, uye hukuru hwese. Uyezve, isu tinokwanisa kukwidziridza chimiro, kusanganisira madhizaini asina makona akapinza kana maburrs, uye neshanduko dzakatenderedzwa kudzikisa kushushikana, kunatsiridza kuramba kuneta, uye kudzivirira kuunganidzwa kwemvura, kuunganidza guruva, uye crevice corrosion.
Mapurojekiti akasiyana ane zvakasiyana zvinodiwa zvesimba remakanika, kutyora mutoro, uye chengetedzo chinhu chegora rinodzivirira majoko; saka, kugadzirisa kunogonekawo, kusanganisira kutyora mutoro, kuchengetedza chinhu, uye giredhi resimba, kusangana nezvinodiwa zvemamiriro ekushanda akasiyana.
Zvishandiso ndizvo zvakare musimboti wejoko ndiro. Kusimba kwegoho, kusimba, kurebesa, kuderera-kusimba kwekushisa, kusimba, uye kufambirana nemagetsi zvinogona kugadzirwa. Ehe, kana mune zvimwe zvamunoda, ndapota inzwa wakasununguka kutibata uye tichakupa imwe-imwe mira, mhinduro inogoneka.
Iyo corrosion inodzivirira yejoko rekudzivirira kwehuori kunobva kune yayo corrosion yekudzivirira nzira, iyo musimboti ndeyekuparadzanisa iyo substrate kubva kune inoora nharaunda.
Cathodic chibayiro chekudzivirira
Munzvimbo yesimbi yekuita, zinc ine yakanyanya kukwirira kemikari kuita kupfuura iron. Kana anti-corrosion layer iine makwara madiki, kukuvara, kana maburi, simbi inobuda pachena. Panguva ino, zinc inova anode uye iron inova cathode. Mupfunga wemvura uye pfapfaidzo yemunyu zvinoumba electrolyte. Zinc inonyanya kusvibiswa, kunyungudutswa, uye kupedzwa, nepo simbi isina kupera zvachose, haina ngura, uye haina kurasika. Mune mamwe mazwi, kunyangwe iyo pamusoro peiyo inodzivirira yejoko ndiro ine zvidiki zvikwekwe kana kukuvadzwa kwekudhumhana, simbi yemukati ichiri yakachengetedzwa uye haiite ngura.
Kuzvidzivirira{0}kuzviporesa
Mushure mekunge zinc layer yaitwa oxidized mumhepo, inokurumidza kuumba gobvu, -isina conductive, mvura-isinganyunguriki, uye yakagadzikana basic zinc carbonate passivation film. Iri firimu rekufambisa rinobva ranyatsovhara nzvimbo inoitika ngura, kudzivirira okisijeni nehunyoro kubva mukuenderera mberi kupinda, uye kumisa ngura otomatiki. Iyo simbi isina tsvina yejoko ndiro inotsamira pachromium kugadzira chromium oxide passivation firimu. Kana yakweshwa, inobva yaita neoxygen kuti imutsiridze uye nekupora payo-nekusingaperi, ichiramba yakagadzikana kunyangwe munzvimbo dzakanyanyisa.
Structural corrosion protection optimization
Iyo ndiro yejoko ine nzvimbo yakatsetseka uye isina makona akafa. Panguva yekushandiswa, inodzivirira kunyudzwa mumvura kwenguva refu, kuunganidzwa kweguruva uye kunwa mwando, kukoromoka kwemukororo, uye kumucheto kwakapinza uye makona zvinoita kuti pave negomba, kukuvadzwa kwependi, uye kuora mwoyo. Kunyanya kana uchitumira kunze, chamfering, polishing, uye deburring inoitwa kubvisa ngura kubva muchimiro. Maweld and spliced parts are high{{4}nzvimbo dzine njodzi yekuora. Panguva yekugadzirwa, chero zvinhu zvinokuvadza zvinofanira kudzivirirwa.
