Amacandelo amabini aphezulu epeyinti eqinileyo ephezulu, ukumelana kakuhle namanzi olwandle, imichiza, ukunxitywa kunye nokuchithwa kwecathodic
Iimbonakalo
Ukuncamathela okugqwesileyo kunye nokusebenza kwe-anti corrosion, ukuxhathisa okugqwesileyo kwe-cathodic disbandment.
Ukuxhathisa okugqwesileyo kwe-abrasion.
Ukumelana okugqwesileyo kokuntywiliselwa emanzini;ukuxhathisa okulungileyo kweekhemikhali.
Iimpawu ezigqwesileyo zoomatshini.
Iingubo zaselwandle ezinqanda ukubola, njengazo zonke iipeyinti ze-epoxy, mhlawumbi itshokhwe kwaye iphele ixesha elide ekuvezweni kwiatmosfera engqongileyo.Nangona kunjalo, le nto ayichaphazeli ukusebenza kwe-anti-corrosion.
I-DFT 1000-1200um inokufikelelwa ngoluhlu olulodwa, aluyi kuchaphazela ukunamathela kunye nokusebenza kokuchasana nokubola.Oku kuya kwenza lula iinkqubo zesicelo kunye nokuphucula ukusebenza kakuhle.
Ukusetyenziswa ngokubanzi, ubukhulu befilimu bucetyiswa phakathi kwe-500-1000 um.
Usetyenziso olucetyiswayo
Ukukhusela izakhiwo zetsimbi kwiindawo ezinobungozi obunzima, njengeendawo ezingaphantsi kwamanzi zezakhiwo ezingaphandle kwe-offshore, izakhiwo zemfumba, ukukhuselwa kodonga lwangaphandle lwemibhobho engcwatywe, kunye nokukhuselwa kwesakhiwo sentsimbi kwiindawo ezifana namatanki okugcina, izityalo zekhemikhali, kunye nezixhobo zephepha.
Ukongeza i-aggregate efanelekileyo engatyibilikiyo ingasetyenziswa njengenkqubo yokwambathisa engatyibilikiyo.
I-coating enye inokufikelela kubukhulu befilimu eyomileyo engaphezu kwe-1000 microns, eyenza lula kakhulu iinkqubo zesicelo.
Imiyalelo yesicelo
I-Substrate kunye nonyango lwangaphezulu
Intsimbi:Yonke imiphezulu kufuneka icoceke, yome kwaye ingabi nazingcolisi.I-oyile kunye negrisi kufuneka zisuswe ngokuhambelana nomgangatho wokucoca i-solvent ye-SSPC-SP1.
Ngaphambi kokufaka ipeyinti, yonke imiphezulu kufuneka ihlolwe kwaye iphathwe ngokuhambelana ne-ISO 8504: 2000 standard.
Unyango loMphezulu
I-Sandblasting yokucoca indawo ukuya kwi-Sa2.5 (ISO 8501-1: 2007) kwinqanaba okanye i-SSPC-SP10, i-surface roughness 40-70 microns (2-3 mils) iyacetyiswa.Iziphene zobuso obuvezwa ngokuqhunyiswa kwesanti kufuneka zifakwe isanti, zizaliswe okanye ziphathwe ngendlela efanelekileyo.
Umphezulu ovunyiweyo we-primer kufuneka ucoceke, wome, kwaye ungabi neetyuwa ezinyibilikayo kunye nazo naziphi na ezinye izinto ezingcolisa umphezulu.Iiprimers ezingavunywanga kufuneka zicocwe ngokupheleleyo kwinqanaba le-Sa2.5 (ISO 8501-1: 2007) ngokuqhunyiswa kwesanti.
Gqibezela:Ifanelekile ukugquma kuluhlu oluthile oluqinileyo kunye olupheleleyo lokuguga.Kodwa uvavanyo lwendawo encinci kunye novavanyo luyafuneka ngaphambi kokusetyenziswa.
Omnye umphezulu:nceda uqhagamshelane ne-ZINDN.
Iyasebenza kwaye iyanyangwa
● Ubushushu bemo engqongileyo kufuneka bube ukusuka kwi-5℃ ukuya kwi-38℃, ukufuma komoya okunxulumeneyo akufunekanga kube ngaphezu kwe-85%.
● Ubushushu be-substrate ngexesha lokufakwa kunye nokunyanga kufuneka lube yi-3℃ ngaphezu kwendawo yombethe.
● Ukusetyenziswa kwangaphandle akuvumelekanga kwimozulu embi njengemvula, inkungu, ikhephu, umoya onamandla kunye nothuli olunzima.Ngexesha lokunyanga ukuba ifilimu yokugquma phantsi komswakama ophezulu, i-amine salts ingenzeka.
● Ukujiya ngexesha okanye ngokukhawuleza emva kokufakwa kwesicelo kuya kubangela ukuba umphezulu ube buthuntu kunye nomgangatho ophantsi wokugquma.
● Ukuchanabeka kwangaphambi kwexesha kumanzi amileyo kunokubangela ukutshintsha kombala.
