Wakavhiringika Nezve Simbi Chimiro Anti-Corrosion? Zvakajairika Sarudzo & Sarudzo Mazano

Simbi chimiroanti-corrosion yakakosha kuwedzera hupenyu hwesevhisi yezvivakwa. Corrosion dziviriro zvirongwa zvinosiyana zvichienderana nenzvimbo dzakasiyana dzechisikigo uye sevhisi. Kuongorora kwakadzama kuchaitwa kune ese ari maviri kugadzirira kwepamusoro uye anti-corrosion matanho ekudzikisa ekutanga mari yekuvaka uye kuwedzera hupenyu hwechivako.

Mhando dzese dzezvivakwa dzinoenderana nekukanganiswa kwenzvimbo dzinoora, izvo zvinoiswa muzvikamu zvakasiyana zvekuora zvichienderana nemamiriro ebasa.

Zvirongwa zvakasiyana zve-anti-corrosion zvichasarudzwa kuti zvigadzirise nzvimbo dzakasiyana-siyana dzinoparadza. Hazvina mhosva kuti mhinduro ipi inogamuchirwa, kugadzirira kwepamusoro kunoisa hwaro hwekudzivirirwa kwekuora uye inotarisa kana iyo yekudzivirira inogona kuita seyakagadzirirwa. Kazhinji, kuputika kwejecha kana kuputika kwepfuti kunoshandiswa pakubvisa ngura yemashopu ekugadzira simbi, ine hutsanana hushoma hwegiredhi reSa2.5, inotsanangurwa seyakanyanya kuputika kuchenesa. Mukuwedzera, iyo yekutanga ngura yegiredhi yesimbi substrates inofanira kuverengerwa. Raw zvinhu zvisingagone kuzadzisa chiyero chinodiwa kunyangwe mushure mekurapwa kwepamusoro zvichatsiviwa kana kuraswa.

Paunenge wapedza kugadzirira kwepamusoro, danho rinotevera nderekusarudza iyo anti-corrosion system. Kumwaya pendi uye kupisa-dip galvanizing ndiwo maviri makuru mhinduro. Kunze kwezvo, nzira dzinoverengeka dzakaratidzwa dzakakura dzinopesana necorrosion dzinogamuchirwa zvakanyanya mumapurojekiti anoshanda: 

(1) Weeathering simbi inogadzirisa nyaya dzekuora, inoshanda kune chikamu chekunzezvivakwa zvesimbi, asi nezvinonetsa zvekudhura zvakanyanya uye kutaridzika zvakanaka. 

(2) Thermal spraying (aluminium spraying / zinc spraying) inopa kushanda kwakaenzana nekupisa-dip galvanizing uye inoratidzira zvirinani kuchinjika kune zvikamu zvezvikamu, zvakanakira nhengo dzakakosha dzesimbi uye nharaunda dzinoparadza zvakanyanya.

(3) Dziviriro yeCathodic inotsamira pane electrochemical anti-corrosion misimboti, inonyanya kushandiswa kune zvivakwa zvesimbi zvakanyudzwa pasi pemvura kana kuvigwa pasi pevhu. Magadzirirwo edziviriro anoumbwa anoumbwa anoshanda sedzimwe sarudzo dzinopfuura dzakajairwa mhinduro, dzakadai seyakasanganiswa anti-corrosion uye inodzivirirwa nemoto coatings uye graphene heavy-duty anti-corrosion coatings.

Multi-Layer Spray Coating System

Iyo spray coating anti-corrosion system yezvimiro zvesimbi inovaka akawanda-layer ekudzivirira machira pane echikamu nzvimbo ane mabasa akasiyana, ayo anonyanya kukamurwa kuita matatu akaturikidzana: primer, yepakati jasi uye topcoat. Iyo primer inoshandira kunamatira uye kudzivirira ngura. Epoxy zinc-rich primer ine zinc content isingasviki 70% inowanzoshandiswa. Inorganic zinc-rich primer ndiyo imwe nzira, asi iyo yakaoma firimu ukobvu inoda kudzora kwakasimba. Epoxy micaceous iron oxide yepakati jasi inoshandiswa kune yepakati layer, uye aliphatic polyurethane topcoat kana fluorocarbon topcoat inogamuchirwa sejasi rekupedzisa. Ese maitirwo emushonga wekupfapfaidza achapedzwa mufekitari imwe chete kuti ive nechokwadi chekugadzirwa kwakadzikama uye kuita kwakavimbika kwekudzivirira-kuora.

Galvanizing

Galvanizing inokamurwa kuita inopisa-dip galvanizing uye electro-galvanizing (yakajairika galvanizing). Kupisa-dip galvanizing (zita rizere: hot-dip galvanization) inodzivirira zinc coating nekunyudza simbi mubhavhu rezinc rakanyungudutswa. Iyo inoratidzira gobvu zinc layer kubva pa65μm kusvika 200μm. Iine corrosion yakasarudzika kuramba, hupenyu hurefu hwesevhisi, kunamatira kwakasimba uye yakapusa maitiro, ine dhizaini yekutaridzika kwepakati uye inokodzera mahombe-akaumbwa zvimiro. Electro-galvanizing deposits zinc coating based on electrolysis principle. Zinc layer yaro yakatetepa, kazhinji 20μm kusvika 30μm. Iyo inozvirumbidza yakanaka yekushongedza mhedzisiro asi yakaoma kugadzirwa, iyo inoshanda kune diki diki zvidimbu kana zvimiro zvinoda mwenje anti-corrosion dziviriro.

Corrosion protection yesimbi chimiro workshopsinotanga nekusimbisa chikamu chekuora chenzvimbo yekushanda, kupedzisa kugadzirira kwepamusoro kwepamusoro uye kusarudza yakakodzera anti-corrosion solution. Semugadziri wesimbi ane hunyanzvi, EHSS ine humbowo hwakadzama hwezvese anti-corrosion maitiro uye inogona kukubatsira mukusarudza inochengetedza mutengo uye yakakwirira-inoshanda kudzivirira ngura.
