Kuwedzera corrosion-protection coatings uye chisimbiso matanho anogona kudiwa kune yakakwirira-sarufa marasha kana mapurojekiti emahombekombe.
Ndeapi Mapurojekiti Anofanirwa Kufunga Yakavharirwa Marasha Kuchengetera?
Sarudzo yacho inowanzoenderana nezvinhu zvitatu zvinoti: mari yekushanda kwepagore, mutengo wemarasha nemhando, uye zvinodiwa nemitemo uye kuwanikwa kwevhu.
Nekuita kwakaderera-kuburikidza, nguva yekubhadhara inogona kuwedzera kupfuura makore gumi, zvichiita kuti dura rakavhurika rine guruva-kudzvinyirira zvikirini sarudzo ine musoro.
Pamitengo yemarasha akakwira kana mhando dzemarasha anopisa, nzvimbo yakavharirwa inogona kupa hupfumi hwakawanda. Munzvimbo dzine hanya nenharaunda, zviteshi kana nzvimbo dzine ivhu shoma, yakavharirwa haisi sarudzo yehupfumi chete - inogona kunge iri chinodikanwa chekubvumidzwa kweprojekiti kana kuenderera mberi nekushanda.
Kana zvingangoita zviviri zvezvinhu zvitatu izvi zvichifarira kuvharirwa, kugoneka kuri pamutemo uye kuongorora mutengo kwakakodzera kuitwa.
Mibvunzo Inowanzo bvunzwa
Q1: Chivakwa chemarasha chakavharirwa zvizere chinodhura zvakadini?
Pachimiro chesimbi chine mavara-akavharwa simbi machira, inofungidzirwa mutengo mukuru wekuvaka i $63–92/m². Izvi hazvibatanidzi stacking uye kudzoreredza midziyo, kurapwa kwenheyo uye masisitimu ekudzivirira moto. Mutengo chaiwo wepurojekiti unofanirwa kuverengerwa zvichienderana nekureba, kureba kwemaeves, mamiriro epasi uye zvimwe zvinodikanwa zveprojekiti.
Q2: Ndeipi yakanyanya hupfumi: dome rekuchengetera marasha kana kureba rakavharirwa shedhi?
Kune imwechete yekuchengetedza huwandu, denderedzwa dome rinowanzo shandisa simbi shoma pachikamu chepasi uye inoda pasi shoma. Zvisineyi, kana mabatirwo akaitwa zvinhu achida longitudinal stockyard ine portal-type reclaimer uye maconveyor akareba, dome rinogona kunge risingaenderani nehurongwa hwekushandisa. Iyo barrel-vault chimiro kana truss system inogona kuzove yakakosha.
Q3: Chivakwa chakavharirwa zvizere chekuchengetera marasha chinosangana nezvinodiwa zvekudzora guruva here?
Kwete. Yakazara yakavharwa ndiyo huru yekudzora chiyero, asi kufefetedza, mhute-kudzvinyirira masisitimu uye manejimendi ekushanda zvichiri kudikanwa.
Kuunganidza gasi uye kuputika kweguruva remarasha kunofanirawo kudzivirirwa mukati mechivakwa. Yakakodzera mhepo yekufefetera uye gasi yekutarisa masisitimu angave akadikanwa, nepo kurodha uye kurodha mapoinzi achiri kuda kudzvanywa kweguruva. Enclosure haibvisi kudiwa kwemaitiro ekudzora.
Q4: Yadhi yemarasha iripo yakavhurika inogona kuvharirwa pasina kumisa mabasa?
Kuvaka kwakapetwa kunogona kuita kuti izvi zvigoneke. Imba yezvitoro inogona kukamurwa kuita zvikamu, chimwe chikamu chakavharirwa nepo chimwe chichienderera mberi chichishanda, chichitsigirwa nekubata zvinhu zvenguva pfupi uye gadziriro dzokutama.
Iyi nzira inoda danho rekuvaka uye kuchengetwa kwemarasha kwenguva pfupi kuti zvipinzwe mukugadzira kubva pakutanga.
Q5: Inguva yakareba sei furemu yenzvimbo inogona kuramba yakachengetedzwa kubva mukuora?
Zvivako zvekuchengetera marasha zvinogona kuoneswa zviri pakati nepakati kune zvinosvibisa zvakanyanya. Nekupisa-kunyura kwakanangidzirwa kweinenge 85 μm uye kugara uchiongorora, dhizaini yehupenyu hwemakore makumi maviri nemashanu inogona kutariswa, zvichienderana nemamiriro ezvinhu chaiwo uye kutsanangurwa kweprojekiti. Ongorora kudzikira kwekupfeka kwega kwega 2-3 makore seyakakurudzirwa kugadzirisa nguva. Kana inopfuura 70% ye zinc coating yakadyiwa, kudzokorora kunofanirwa kutariswa zvichitevera kuongororwa kwehunyanzvi.
