Iipleyiti yentsimbi enombalakwimo engqongileyo ye-atmospheri bachanabeke kukukhanya kwelanga, umoya, isanti, imvula, ikhephu, iqabaka nombethe, kunye nokutshintsha kobushushu kunye nokufuma unyaka wonke.Ezi zizinto zonke ezibangela ukuba iithayile zetsimbi zombala zidle.Ngoko bakhuselwa njani?
1. Thermal spray aluminiyam composite ukutyabeka
Le yindlela ehlala ixesha elide yokunqanda umhlwa esebenza njenge galvanizing yediphu eshushu.Indlela ekhethekileyo kukuqala nge-sandblast kwaye ususe umhlwa kumphezulu wezixhobo zentsimbi ukuveza ukukhazimla kwesinyithi kunye nokurhaxa umphezulu.Emva koko sebenzisa i-acetylene-oksijeni ilangatye ukunyibilikisa i-aluminiyam yocingo oluqhubekayo, kwaye usebenzise umoya ocinezelweyo ukuwuvuthela phezu kwendawo yentsimbi ukwenza i-aluminiyam yokutshiza yobusi.Ekugqibeleni, i-capillary pores izaliswe ngepeyinti efana ne-epoxy resin okanye ipeyinti ye-neoprene ukwenza i-coating composite.Le ndlela ayinakusetyenziswa eludongeni lwangaphakathi lwamacandelo e-tubular, ngoko ke zombini iziphelo zamacandelo e-tubular kufuneka zitywinwe ngomoya ukuze udonga lwangaphakathi lungayi kugqwala.
2. Indlela yokwaleka
Iipropathi zokunqanda ukubola kweendlela zokwaleka ngokuqhelekileyo azikho zilungileyo njengeendlela zokunqanda ukubola kwexesha elide.Ngoko ke, zininzi izakhiwo zentsimbi zangaphakathi okanye izakhiwo zentsimbi zangaphandle ekulula ukuzikhusela.Inyathelo lokuqala ekwakhiweni kwendlela yokwaleka kukususa umhlwa.Ukwaleka okugqwesileyo kuxhomekeke ekususweni komhlwa ngokucokisekileyo.Ke ngoko, iileyiti ezinemfuno ephezulu zisebenzisa i-sandblasting kunye nokudutyulwa kokudubula ukususa umhlwa, ukuveza ukukhazimla kwesinyithi, kwaye kususe onke amabala erusi kunye ne-oyile.Iingubo ezifakwe kwisiza zinokususwa ngesandla.Ukukhethwa kwengubo kufuneka kuthathelwe ingqalelo indawo engqongileyo.Iingubo ezihlukeneyo zineemeko ezahlukeneyo zokunyamezela kwiimeko ezahlukeneyo zokubola.Iingubo ngokubanzi ziquka i-primer kunye ne-topcoat.I-primer iqulethe umgubo ongaphezulu kunye nesiseko esincinci.Ifilimu irhabaxa, incamathele ngamandla kwintsimbi, kwaye incamathele kakuhle kwidyasi yangaphezulu.I-topcoat inezinto ezininzi ezisisiseko kwaye ifilimu iyakhazimula, enokukhusela i-primer kwi-corrosion ye-atmospheric kunye nokumelana nesimo sezulu.
Kukho imibuzo malunga nokuhambelana kweengubo ezahlukeneyo.Xa ukhetha iingubo ezahlukeneyo ngaphambi nangemva, kufuneka ubeke ingqalelo ukuhambelana kwazo.Ukwaleka kufuneka kusetyenziswe ngobushushu obufanelekileyo kunye nokufuma.Indawo yokwakhiwa kwengubo kufuneka ibe nothuli oluncinci kwaye akufanele kubekho ukuxinana kumphezulu wamacandelo.Musa ukubeka imvula kwiiyure ezi-4 emva kokupeyinta.Ukugquma ngokuqhelekileyo kwenziwa amaxesha ama-4 ukuya kuma-5.Ubunzima obupheleleyo befilimu yepeyinti eyomileyo yi-150μm kwiiprojekthi zangaphandle kunye ne-125μm kwiiprojekthi zangaphakathi, kunye nephutha elivumelekileyo le-25μm.Elwandle okanye elwandle okanye kwindawo enomhlwa kakhulu, ubukhulu obupheleleyo befilimu yepeyinti eyomileyo inokunyuswa ukuya kwi-200 ~ 220μm.
3. Indlela yokukhusela yeCathodic
Ukufakela isinyithi esicacileyo ngakumbi kumphezulu wesakhiwo sentsimbi sithatha indawo ye-corrosion yentsimbi.Ngokuqhelekileyo isetyenziswa phantsi kwamanzi okanye izakhiwo ezingaphantsi komhlaba.Iithayile zetsimbi zombala ziyimveliso eneendleko kakhulu.Nangona utyalo-mali lokuqala lwenkunzi lunokubonakala luncinci, ngokweendleko zokusetyenziswa kwexesha elide, luyonga iindleko kuba imveliso inobomi obude benkonzo kwaye akukho ziko.Kukho imeko yokutshintshwa.Kithina, igcina umsebenzi, umzamo kunye nemali.
Ndiyathemba ukuba eli nqaku liluncedo kuwe.Nceda uvale le webhusayithi ukuze ufumane iindaba ezihlaziyiweyo.
