Ubungakanani besicelo
Ifanelekile kunyango lokuchasana ne-corrosion yecala langaphakathi le-flue.Uhlobo I ilungele unyango anti-umhlwa kumphezulu ukudibana ngqo nerhasi flue, kunye umda ukumelana nobushushu 250℃ kunye sulfuric acid ukuthotywa ukuxhathisa umda yoxinaniso 40%.
Imiyalelo yesicelo
I-Substrate esebenzayo kunye noNyango loMphezulu
I-1, unyango lwe-Steel substrate: ukuqhunyiswa kwesanti okanye ukudutyulwa kokudubula ukususa umhlwa ukuya kwinqanaba le-Sa2.5, uburhabaxa 40 ~ 70um, ukunyusa ukunamathela kwengubo kunye ne-substrate.
2, Xa usebenzisa, xuba icandelo A kuqala, emva koko yongeza i-ejenti yokunyanga icandelo B ngokulinganayo, xuba ngokulinganayo, gcina ixesha lokungeniswa kwemizuzu eyi-15 ~ 30, lungisa i-viscosity yesicelo kunyeinani elifanelekileyookhethekileyo obhityileyo ngokweendlela zokusetyenziswa.
Iindlela zokusetyenziswa
1, Isitshizi esingenamoya, isitshizi somoya okanye irola
I-brush kunye ne-roller yokugqoka inconywa kuphela ngengubo yomgca, ukugquma kwendawo encinci okanye uthinte phezulu.
I-2, Ubunzima befilimu eyomileyo ecetyiswayo: 300um, umaleko omnye wokugquma malunga ne-100um.
I-3, Ngenxa yokuba indawo enobungozi inzima kakhulu, kwaye i-coating elahlekileyo iya kubangela ukuba insimbi idle ngokukhawuleza, ukunciphisa ubomi benkonzo.
ngenxa yokusetyenziswa kwendawo engcolileyo yefilimu yokugqoka ibe yomelele kakhulu, ukuvuza kuya kwenza i-coating corrode ngokukhawuleza kwaye inciphise ubomi benkonzo.
Desulfurization & denitrification isixhobo yangaphakathi imiyalelo isicelo eludongeni
Unyango lomphezulu
I-oyile okanye igrisi kufuneka isuswe ngokwemigangatho ye-SSPC-SP-1 yokucoca i-solvent.
Kunconywa ukutshiza ukuphatha ubuso bentsimbi kwi-Sa21/2 (ISO8501-1: 2007) okanye umgangatho we-SSPC-SP10.
Ukuba i-oxidation iyenzeka kumphezulu emva kokutshiza kwaye ngaphambi kokupeyinta le mveliso, ke umphezulu kufuneka uhlaziywe kwakhona.Hlangana nemigangatho ebonakalayo echaziweyo.Iziphene zobuso obuvezwayo ngexesha lokutshiza kufuneka zifakwe isanti, zizaliswe, okanye ziphathwe ngokufanelekileyo.Uburhabaxa bomphezulu obucetyiswayo bungama-40 ukuya kuma-70μm.Amanzi aphantsi anyangwa ngokuqhunyiswa kwesanti okanye ngokuqhushumba kwembumbulu kufuneka aqaliswe kwiiyure ezi-4.
Ukuba i-substrate ayiphathwanga kwinqanaba elifunekayo, liya kubangela ukubuya kwe-rust, ifilimu yepeyinti ye-flaking, iziphene zefilimu yepeyinti ngexesha lokwakhiwa, njl.
Umyalelo wokusetyenziswa
Ukuxuba: Imveliso ihlanganiswe ngamacandelo amabini, iQela A kunye neQela B. Umlinganiselo uhambelana nenkcazo yemveliso okanye ileyibhile kwi-barrel yokupakisha.Xuba icandelo le-A kakuhle kunye nesixhumi samandla kuqala, uze udibanise icandelo le-B ngokulinganayo kwaye uvuselele kakuhle.Yongeza inani elifanelekileyo le-epoxy thinner, i-dilution ratio ye-5 ~ 20%.
Emva kokuba ipeyinti ixutywe kwaye ixutywe kakuhle, yiyeke ivuthwe i-10 ~ 20 imizuzu ngaphambi kokuba ifakwe.Ixesha lokuvuthwa kunye nexesha elisebenzayo liya kufinyezwa njengoko ubushushu buphakama.Ipeyinti emiselweyo kufuneka isetyenziswe ngaphakathi kwexesha elisemthethweni.Ipeyinti edlula ixesha elimiselweyo kufuneka ilahlwe yinkunkuma kwaye akufanele isetyenziswe kwakhona.

Iindlela zokusetyenziswa
Ukutshiza okungenamoya kuyacetyiswa kulwakhiwo lwendawo enkulu, ukutshiza umoya, ukubrasha okanye ukugquma ngerola nako kungasetyenziswa.Ukuba ukutshiza kusetyenzisiwe, i-weld seams kunye neekona kufuneka zipeyintwe kwangaphambili, ngaphandle koko, kuya kubangela ukumanzisa okungahambi kakuhle kwepeyinti kwi-substrate, ukuvuza, okanye ifilimu yepeyinti ebhityileyo, okubangela ukurusa kunye nokuxobula ifilimu yepeyinti.
Ukunqumama xa usebenza: Musa ukushiya ipeyinti kwiityhubhu, imipu, okanye izixhobo zokutshiza.Gubha zonke izixhobo ngokucokisekileyo nge-thinner.Ipeyinti akufanele iphinde ivalwe emva kokuxuba.Ukuba umsebenzi unqunyanyisiwe ixesha elide, kucetyiswa ukuba usebenzise ipeyinti entsha edibeneyo xa uqalisa umsebenzi.
Ukulumkela
Le mveliso i-anti-corrosion i-coating ekhethekileyo yodonga lwangaphakathi lwe-desulfurization kunye nesixhobo se-denitrification, umgangatho ongezantsi luhlobo olulodwa, olunokumelana nokunyuka kwe-abrasion, ukuxhathisa okulungileyo kwe-asidi (i-40% ye-asidi ye-sulfuric), kunye nokumelana nokutshintsha kobushushu obuhle.Ngethuba lokwakha, isibhamu sokutshiza, ibhakethi yepeyinti, ibrashi yokupenda, kunye ne-roller akufanele ixutywe, kwaye izinto ezipeyintiweyo ngale mveliso akufanele zingcoliswe kunye nezinye iipende eziqhelekileyo.
Ukuhlolwa kwefilimu yokugubungela
a.Ibrashi, i-rolling, okanye isitshizi kufuneka igalelwe ngokulinganayo, kungabikho kuvuza.
b.Ukutshekisha ukutyeba: emva koluhlu ngalunye lwepeyinti, jonga ubukhulu, emva kokuba yonke ipeyinti ijonge ubukhulu bepeyinti yepeyinti, amanqaku okulinganisa ngokweemitha ezili-15 zesikwere, i-90% (okanye i-80%) yamanqaku alinganisiweyo kufuneka ukufikelela kwixabiso elichaziweyo lokutyeba, kwaye ubukhulu obungafikeleli kwixabiso elichaziweyo abuyi kuba ngaphantsi kwe-90% (okanye i-80%) yexabiso elichaziweyo, kungenjalo ipeyinti kufuneka iphindwe.
c.Ubunzima obupheleleyo bengubo kunye nenani leendlela zokugubungela kufuneka zihlangabezane neemfuno zoyilo;umphezulu kufuneka ugudiswe kwaye ungabi namanqaku, uhambelana nombala, ngaphandle kwemingxuma, amaqamza, ageleza ezantsi, kunye nokuqhekeka.
d.Ukuhlolwa kwembonakalo: Emva kokwakhiwa kwepeyinti nganye, inkangeleko kufuneka ihlolwe, ijongwe ngeliso lenyama okanye i-5 yeglasi yokukhulisa amaxesha, kunye nemingxuma, iintanda, ukukrazula, ukuvuza kwepeyinti kunye nokuvuza kwepeyinti kufuneka kulungiswe okanye kupeyintwe kwakhona, kunye nenani elincinci lokulenga. kuvunyelwe ukubakho.Iimfuno ezithile zomgangatho wokugquma zezi zilandelayo:
| Izinto zokuhlola | Iimfuno zomgangatho | Iindlela zokuhlola |
| Ukukrazula, ukuvuza kwebrashi, i-pan rust, kunye nokungena komzantsi | Ayivumelekanga | Ukuhlolwa okubonakalayo |
| Umngxuma wokuqhafaza | Ayivumelekanga | 5 ~ 10x ulwandiso |
| Ulusu oluqukuqelayo, olushwabeneyo | Ayivumelekanga | Ukuhlolwa okubonakalayo |
| Ukomisa ubukhulu befilimu | Akukho ngaphantsi kobukhulu boyilo | Imilinganiselo yeMagnetic Ukutyeba |
Imiqathango yesicelo kunye nezithintelo
Ubushushu be-Ambient kunye ne-substrate:5-40℃;
Isiqulatho samanzi kwi-substrate:<4%<br/>Ukufuma komoya okufanelekileyo:Ukufuma okuhambelanayo ukuya kuthi ga kwi-80%, imvula, inkungu, kunye neentsuku zekhephu azinakwakhiwa.
Indawo yombethe:Ubushushu bomphezulu we-substrate bungaphezulu kwe-3℃ ngaphezu kwendawo yombethe.
Ukuba yakhiwe phantsi kwendawo engahambelani neemeko zokwakha, i-coating iya kudibanisa kwaye yenza ifilimu yepeyinti iqhakaze, i-blister, kunye nezinye iziphene.
Le mveliso ayichasananga nokukhanya kwe-ultraviolet, ngoko kuyacetyiswa kwiindawo zangaphakathi.
Amanyathelo okhuseleko
Le mveliso kufuneka isetyenziswe kwindawo yokuvelisa ngabaqhubi beengcali zokupeyinta phantsi kwesi sikhokelo somyalelo, iphepha ledatha yokhuseleko lwezinto eziphathekayo, kunye nemiyalelo kwisitya sokupakisha.Ukuba olu xwebhu lweDatha yoKhuseleko lweMathiriyeli (MSDS) alufundwanga;le mveliso akufanele isetyenziswe.
Konke ukutyabeka kunye nokusetyenziswa kwale mveliso kufuneka kwenziwe phantsi kwayo yonke impilo yesizwe efanelekileyo, ukhuseleko, kunye nemigangatho kunye nemimiselo yokusingqongileyo.
Ukuba i-welding okanye ukusika i-flame kufuneka kuqhutywe kwintsimbi ehlanganiswe nale mveliso, uthuli luya kukhutshwa, kwaye ngoko ke izixhobo ezifanelekileyo zokukhusela zomntu kunye nokukhupha umoya owaneleyo wendawo kuyadingeka.
Ugcino
Ingagcinwa kangangeenyanga ezili-12 ubuncinane kwiqondo lobushushu elingama-25°C.
Emva koko kufuneka ihlolwe kwakhona ngaphambi kokusetyenziswa.Gcina kwindawo eyomileyo, enomthunzi, kude nobushushu kunye nemithombo yomlilo.
Isibhengezo
Ulwazi olunikelwe kule ncwadana lusekelwe kwilabhoratri yethu kunye namava asebenzayo kwaye kujongwe njengereferensi kubathengi bethu.Ekubeni iimeko zokusetyenziswa kwemveliso zingaphaya kwamandla ethu, sinika kuphela isiqinisekiso somgangatho wemveliso ngokwayo.
