Themtundu zitsulo mbalem'mlengalenga amakumana ndi kuwala kwa dzuwa, mphepo, mchenga, mvula, matalala, chisanu ndi mame, komanso kusintha kwa kutentha ndi chinyezi chaka chonse.Izi ndi zinthu zonse zomwe zimapangitsa kuti matailosi amtundu wachitsulo awonongeke.Ndiye mungawateteze bwanji?
1. Thermal spray aluminium composite ❖ kuyanika
Iyi ndi njira yolimbana ndi dzimbiri yokhalitsa yomwe imagwira ntchito ngati galvanizing ya dip yotentha.Njira yeniyeni ndiyoyamba kuphulika kwa mchenga ndikuchotsa dzimbiri pamwamba pazitsulo zazitsulo kuti ziwonetsere zitsulo zonyezimira ndikugwedeza pamwamba.Kenaka gwiritsani ntchito lawi la acetylene-oksijeni kuti musungunule waya wa aluminiyamu womwe umadyetsedwa mosalekeza, ndipo gwiritsani ntchito mpweya woponderezedwa kuuzira pamwamba pa chitsulocho kuti mupange zokutira zopopera ngati zisa za aluminiyamu.Pomaliza, ma pores a capillary amadzazidwa ndi utoto monga epoxy resin kapena penti ya neoprene kuti apange zokutira zophatikiza.Njirayi siyingagwiritsidwe ntchito pakhoma lamkati la zigawo za tubular, kotero kuti mapeto onse a zigawo za tubular ayenera kukhala otsekedwa ndi mpweya kuti khoma lamkati lisawonongeke.
2. Njira yokutira
Zotsutsana ndi dzimbiri za njira zokutira nthawi zambiri sizikhala zabwino ngati njira zothana ndi dzimbiri zazitali.Choncho, pali zitsulo zambiri zamkati kapena zitsulo zakunja zomwe zimakhala zosavuta kuteteza.Gawo loyamba pomanga njira yokutira ndikuchotsa dzimbiri.Kupaka bwino kumadalira kuchotsa dzimbiri.Choncho, zokutira zofunidwa kwambiri nthawi zambiri zimagwiritsa ntchito sandblasting ndi kuwombera mfuti kuchotsa dzimbiri, kuvumbulutsa kunyezimira kwachitsulo, ndikuchotsa dzimbiri ndi mafuta.Zopaka zomwe zimagwiritsidwa ntchito pamalowo zitha kuchotsedwa ndi manja.Kusankhidwa kwa zokutira kuyenera kuganizira malo ozungulira.Zopaka zosiyanasiyana zimakhala ndi kulolerana kosiyana ndi zikhalidwe zosiyanasiyana za dzimbiri.Zovala nthawi zambiri zimakhala ndi primer ndi topcoat.Choyambira chimakhala ndi ufa wambiri komanso zinthu zochepa zoyambira.Filimuyi ndi yaukali, imamatira mwamphamvu kuchitsulo, ndipo imamatira bwino chovala chapamwamba.Chovala chapamwamba chimakhala ndi zipangizo zambiri zoyambira ndipo filimuyo ndi yonyezimira, yomwe ingateteze chiyambi cha mlengalenga ku dzimbiri komanso kukana nyengo.
Pali mafunso okhudzana ndi kugwirizana kwa zokutira zosiyanasiyana.Posankha zokutira zosiyana musanayambe ndi pambuyo pake, muyenera kumvetsera kugwirizana kwawo.Chophimbacho chiyenera kuikidwa ndi kutentha koyenera ndi chinyezi.Malo omangira zokutira ayenera kukhala ochepa fumbi ndipo pasakhale condensation pamwamba pa zigawo zikuluzikulu.Osawonetsa mvula mkati mwa maola 4 mutatha kujambula.Kupaka nthawi zambiri kumachitika 4 mpaka 5.Makulidwe onse a filimu ya utoto wowuma ndi 150μm pama projekiti akunja ndi 125μm pama projekiti amkati, ndi cholakwika chovomerezeka cha 25μm.M'mphepete mwa nyanja kapena panyanja kapena m'malo owononga kwambiri, makulidwe onse a filimu ya utoto wowuma akhoza kuonjezedwa mpaka 200 ~ 220μm.
3. Njira yachitetezo cha Cathodic
Kulumikiza chitsulo chowoneka bwino kwambiri pamwamba pa chitsulocho kumalowa m'malo mwa chitsulocho.Nthawi zambiri amagwiritsidwa ntchito m'madzi kapena pansi pamadzi.Matailosi achitsulo amtundu ndi okwera mtengo kwambiri.Ngakhale kuti ndalama zoyambira ndalama zoyambira zitha kuwoneka ngati zazing'ono, pankhani ya ndalama zogwiritsira ntchito nthawi yayitali, ndizopulumutsa ndalama chifukwa mankhwalawa amakhala ndi moyo wautali wautumiki ndipo alibe malo.Pali mkhalidwe wolowa m'malo.Kwa ife, zimapulumutsa ntchito, khama ndi ndalama.
Ndikukhulupirira kuti nkhaniyi ndi yothandiza kwa inu.Chonde tsekani tsamba ili kuti mupeze nkhani zatsopano.
