Ko simbi yakavharwa ndiro inoita sei anti-corrosion? Ruvara rwakavharwa simbi ndiro, inozivikanwawo seruvara yakavharwa simbi ndiro, mhedzisiro yekubatanidzwa kwekuita kwekupotera, pre-kurapwa layer, primer, uye topcoat. Isu tinozvidaidza kuti "ina mune imwe anti-corrosion system yevara yakashongedzwa simbi ndiro". Yedu ruvara yakashongedzwa bhodhi inogadzirwa nemhando dzakasiyana dzemachira uye yakaputirwa kuburikidza ne5 zvikamu uye makumi mana nemasere maitiro, ane yakanakisa anti rust zvivakwa.
Corrosion resistance uye inogara kwenguva refu inopera.
Tinowana sei anti-corrosion yemavara akaputirwa simbi mahwendefa? Ruvara rwakavharwa simbi ndiro, inozivikanwawo seruvara yakavharwa simbi ndiro, mhedzisiro yekubatanidzwa kwekuita kwekupotera, pre-kurapwa layer, primer, uye topcoat. Isu tinozvidaidza kuti "ina mune imwe anti-corrosion system yevara yakashongedzwa simbi ndiro".
Iko kupfekedzwa kwemavara simbi ndiro inoita basa rekuzvipira rinopesana nekuora. Zvichitaurwa zviri nyore, inowedzera hupenyu hwesevhisi yeplate yesimbi nekuramba ichidya iyo yekupfeka kwayo. Ehe, mhando, hunhu, uye ukobvu hwekuputira zvinhu zvakakosha mukureba kwekuputira nguva yekushandisa. Ruvara rwedu rwakavharwa mahwendefa esimbi anonyanya kushandisa galvanized, aluminium zingi, galvanized aluminum magnesium uye mamwe mahwendefa esimbi akavharidzirwa kubva kumiti mikuru yesimbi yepamba, ine simba repamusoro uye zvirinani kuramba ngura.
Ngatitaure nezve pre-kurapwa layer zvakare. Ichi chikamu chakakosha cheanti-corrosion yemavara esimbi mahwendefa, ayo anowanzo furatirwa. Iyo pre-atreatment layer, inozivikanwawo se passivation layer, inoda kushandiswa kwepassivation mhinduro senge phosphate kana chromate kupfuudza iyo substrate nzvimbo isati yaiswa ruvara. Izvi hazvisi kungowedzera kusungirirwa kwekuputira, asiwo kunobata basa mukudzivisa kuora. Tsvagiridzo yakaratidza kuti mune yekusarerekera munyu kupfapfaidza kuramba kuyedza kwemarata akavharidzirwa mavara, mupiro weiyo pre-kurapwa layer yemhando inosvika pamusoro pe60%.
Ngatitaure nezve yekutanga zvakare. Kune rumwe rutivi, iyo primer inoita basa mukuwedzera kusungirirwa kwejasi. Mushure mokunge firimu yepende inopindirana, haigoni kubvisa kubva pakuputira, kudzivirira kuputika uye kuvharwa kwekuputira. Kune rimwe divi, nekuda kwekuvapo kwekunonoka-kuburitsa pigments senge chromates mune primer, inogona kupfuudza iyo anode uye nekuvandudza kusimba kwekupotera kwejasi.
Pakupedzisira, ngatitaure nezve topcoat. Kuwedzera kune aesthetics, topcoat inonyanya kushanda kuvhara chiedza chezuva uye kudzivirira UV kukuvadzwa pakuputira. Mushure mekunge topcoat yasvika pane imwe gobvu, inogona kuderedza chizvarwa che micropores, nekudaro ichidzivirira kupinda kweiyo inoparadza midhiya, ichidzikisa mvura uye oksijeni permeability yejasi, uye kudzivirira coating corosion. Kupokana kweUV uye kuwanda kwemajasi akasiyana anosiyana, uye kune imwechete mhando yekupfekedza, ukobvu hwefirimu repende chinhu chakakosha chinokanganisa ngura. Mabhodhi edu akavharwa nemavara anogadzirwa nekusarudza mhando dzakasiyana dzemachira akaporeswa pakupisa kwepamusoro, zvichikonzera kukwirira kwekudzivirira kwecorrosion uye kunogara kwenguva refu anti fading performance.
