Umphantsi wokuzipholisha we-marine anti-fouling coating
Ingcaciso yeMveliso
Ipeyinti ye-self-polishing antifouling yimveliso ekhethekileyo yokugqoka. Ikakhulu ifumana ukusabela kweekhemikhali kumphezulu wengubo. Njengoko inqanawa ihamba emanzini, i-coating iyacotha kwaye ilungelelanise ipolishi kwaye inyibilike ngokwayo. Olu phawu lwenza ukuba umphezulu wenqanawa uhlale ucocekile kwaye unqanda ngokufanelekileyo izinto eziphila elwandle ezifana noonokrwece kunye nealgae ekubeni zincamathele kumkhumbi.
Umgaqo ochasene ne-anti-fouling yepeyinti e-self-polishing antifouling isekelwe kubume bayo beekhemikhali ezizodwa. Iqulethe ezinye iipholima ezisebenza nge-hydrolyzable kunye nezongezo eziyityhefu yebhayoloji. Kummandla wamanzi olwandle, iipholima ziya kuthi kancinane zibene-hydrolyze, ngokuqhubekekayo zihlaziya umphezulu wepeyinti yokungangcolisi, ngelixa izongezo eziyityhefu yebhayoloji zinokunqanda ukuncamathela kwezinto eziphila elwandle kumphezulu osandula ukuvela.
- Xa kuthelekiswa neepeyinti ezinqanda ukungcoliseka, iipeyinti ezizipholisha ngokwazo zineengenelo eziphawulekayo. Emva kokuba iipeyinti zesiNtu ezichasayo zisetyenzisiwe kangangexesha elithile, impembelelo yokuchasana iya kuhla ngokuthe ngcembe, kwaye ukuphinda kusetyenziswe rhoqo kuyafuneka. Oku akudli nje ixesha elininzi kunye neendleko kodwa kusenokuba nefuthe elithile kokusingqongileyo. Ngokwahlukileyo koko, iipeyinti ezizipholisha ngokwazo zinokuthi gqolo zisebenzise impembelelo yazo yokuchasa ixesha elide, zinciphisa ukuphindaphindeka kokugcinwa kwenqanawa okomileyo kunye nokuphinda kusetyenziswe.
- Kwiinkqubo ezisebenzayo, iipeyinti ezizipholishayo ezizicolisisayo zisetyenziswa ngokubanzi kwiintlobo ngeentlobo zeenqanawa, kubandakanywa iinqanawa zabarhwebi, iinqanawa zemfazwe, kunye neeyachts. Kwiinqanawa zabarhwebi, ukugcina i-hull icocekile kunokunciphisa ukuxhathisa ukuhamba kunye nokuphucula ukusebenza kakuhle kwamafutha, ngaloo ndlela kugcinwe iindleko zokusebenza. Kwiinqanawa zemfazwe, ukusebenza kakuhle kokuchasana nokungcola kunceda ukuqinisekisa isantya sokuhamba ngenqanawa kunye nokushukuma kunye nokuphucula ukusebenza kakuhle kokulwa. Kwiiyachts, inokugcina inkangeleko ye-hull ikwimeko entle ngamaxesha onke kwaye iphucule i-aesthetics.
- Ngeemfuno ezingqongqo zokukhuselwa kokusingqongileyo, iipeyinti ezizipholishayo zokuzipholisha nazo zihlala ziphuhla kwaye zivelisa izinto ezintsha. Abasebenzi be-R & D bazibophelele ekunciphiseni ukusetyenziswa kwezongezo ezinobuthi be-biologically kubo ngelixa bephucula ukusebenza kwepeyinti echasene ne-antifouling ukuze bafezekise umphumo ongcono wokusingqongileyo kunye nokusebenza kakuhle kwe-antifouling. Ezinye iipeyinti ezizicocisayo zokuzipholisha zisebenzisa i-nanotechnology ukukhulisa isakhono sazo sokungangcolisi kunye nokusebenza ngokuzipholisha ngokuguqula ubume bemikroskopu yotyatyazo. Kwixesha elizayo, iipeyinti ezizipholishayo ezingazingcolisiyo kulindeleke ukuba zidlale indima enkulu kwinkalo yobunjineli bolwandle kwaye zinike inkxaso eyomeleleyo kuphuhliso loshishino lwaselwandle.
Iimpawu eziphambili
Thintela izinto eziphila elwandle ezenzakaleni ezantsi enqanaweni, ugcine umzantsi ucocekile; Yenza ngokuzenzekelayo kwaye ngokukhawuleza ukwenza ukugulisa ukunciphisa uburhabaxa bomzantsi wenqanawa, kunye nesiphumo esihle sokunciphisa ukutsala; Ayinazitshabalalisi ezisekwe kwi-organotin, kwaye ayinabungozi kwimo engqongileyo yaselwandle.
indawo yesicelo
Isetyenziselwa iindawo ezingaphantsi kwamanzi zomzantsi wenqanawa kunye nezakhiwo zaselwandle, zithintela izinto eziphilayo zaselwandle ukuba zinamathele. Ingasetyenziswa njengepeyinti yokulungisa i-anti-fouling kumzantsi weenqanawa ezibandakanyeka kuhambo lwehlabathi kunye nokuhamba kwexesha elifutshane.

IiMfuno zobuGcisa
- Unyango lomphezulu: Yonke imiphezulu kufuneka icoceke, yome kwaye ingangcoliseki. Kufuneka zivavanywe kwaye ziphathwe ngokuhambelana ne-ISO8504.
- Imiphezulu eqatywe ngepeyinti: Icoca, yomile kwaye ingaguquki. Nceda uqhagamshelane nesebe lobugcisa beziko lethu.
- Ukulungiswa: Iindawo ezinomhlwa, ziphathwa yijethi yamanzi e-ultra-high-high-pressure ukuya kwinqanaba le-WJ2 (NACENo.5/SSPC Sp12) okanye ngokucoca izixhobo zamandla, ubuncinane i-St2 level.
- Eminye imiphezulu: Le mveliso isetyenziselwa ezinye ii-substrates. Nceda uqhagamshelane nesebe lobugcisa beziko lethu.
- Iipeyinti ezihambelanayo emva kwesicelo: I-water-based, i-alcohol-soluble zinc silicate series primers, i-epoxy zinc-rich rich primers, unyango olusezantsi lwe-anti-rust primers, ukususwa okukhethekileyo kwe-rust kunye ne-anti-rust paints, i-phosphate zinc primers, i-epoxy iron oxide zinc anti-rust paints, njl.
- Iipeyinti ezihambelanayo zasemva kwesicelo: Akukho.
- Iimeko zokwakha: Ubushushu bendawo engaphantsi komhlaba kufuneka bungabikho ngaphantsi kwe-0℃, kwaye ubuncinci bube yi-3℃ ngaphezu kobushushu bomoya womoya (iqondo lobushushu kunye nokufuma okunxulumeneyo kufuneka kulinganiswe kufutshane nendawo engaphantsi komhlaba). Ngokuqhelekileyo, umoya omhle uyafuneka ukuqinisekisa ukomisa okuqhelekileyo kwepeyinti.
- Iindlela zokwakha: Ukupeyinta ukutshiza: Ukutshiza okungenamoya okanye ukutshiza ngomoya. Kucetyiswa ukuba usebenzise isitshizi esingenamoya soxinzelelo oluphezulu. Xa usebenzisa ukutshiza ngoncedo lomoya, ingqalelo kufuneka ihlawulwe ekulungiseni i-viscosity yepeyinti kunye noxinzelelo lomoya. Isixa esincinci akufanele sidlule i-10%, ngaphandle koko kuya kuchaphazela ukusebenza kwengubo.
- Ipeyinti yebrashi: Kucetyiswa ukuba kusetyenziswe kwi-pre-coating kunye nepeyinti yendawo encinci, kodwa kufuneka ifikelele kubukhulu obuchaziweyo befilimu eyomileyo.
Amanqaku eNgqwalasela
Le ngubo iqulethe i-pigment particles, ngoko kufuneka ixutywe kakuhle kwaye ixutywe ngaphambi kokusetyenziswa. Ubunzima befilimu yepeyinti echasayo inefuthe elibalulekileyo kwimpembelelo yokuchasana. Ngoko ke, inani leengubo zokugqoka alikwazi ukuncitshiswa kwaye i-solvent ayifanele yongezwe ngokungaqhelekanga ukuqinisekisa ubuninzi befilimu yepeyinti. Impilo noKhuseleko: Nceda uqaphele iimpawu ezilumkisayo kwisikhongozeli sokupakisha. Sebenzisa kwindawo enomoya owaneleyo. Musa ukuphefumlela inkungu yepeyinti kwaye ugweme ukudibana kwesikhumba. Ukuba ipeyinti itshiza esikhumbeni, ngokukhawuleza uhlambulule nge-arhente yokucoca efanelekileyo, isepha kunye namanzi. Ukuba itshiza emehlweni, hlambulula ngamanzi amaninzi kwaye ufune unyango ngokukhawuleza.
