Iphansi elizipholishayo le-marine anti-fouling coating
Incazelo Yomkhiqizo
Upende wokuzipholisha owenziwe nge-antifouling ungumkhiqizo okhethekile wokuhlanganisa. Ngokuyinhloko ibhekana nokusabela kwamakhemikhali ebusweni be-coating. Njengoba umkhumbi uhamba emanzini, ukugqoka kuzopholisha kancane futhi ngokulinganayo futhi kuncibilike ngokwawo. Lesi sici senza ingaphezulu lomkhumbi lihlale lihlanzekile futhi livimbela ngokuphumelelayo izinto eziphilayo zasolwandle njenge-shellfish nolwelwe ekunamatheleni kumkhumbi.
Umgomo ovimbela ukungcoliswa kopende ozipholishayo usekelwe ekwakhekeni kwawo kwamakhemikhali okuyingqayizivele. Iqukethe amanye ama-polymers ane-hydrolyzable kanye nezithasiselo ezinobuthi be-biologically. Emvelweni wamanzi olwandle, ama-polymer kancane kancane azoshintsha i-hydrolyze, ngokuqhubekayo enze kabusha ingaphezulu likapende ongangcolisi, kuyilapho izithasiselo ezinobuthi bebhayoloji zingavimbela ukunamathiselwa kwezinto eziphilayo zasolwandle endaweni esanda kuvezwa.
- Uma kuqhathaniswa nopende bendabuko abanqanda ukungcola, upende ozipholishayo unezinzuzo eziphawulekayo. Ngemva kokusetshenziswa kopende bendabuko bokuvimbela ukungcola isikhathi esithile, umphumela wokuqeda ukungcola uzokwehla kancane kancane, futhi ukuphinda kusetshenziswe njalo kuyadingeka. Lokhu akudli nje kuphela isikhathi esiningi nezindleko kodwa kungase kube nomthelela othile endaweni ezungezile. Ngokuphambene, opende abazipholishayo abangangcolisi bangaqhubeka nokusebenza isikhathi eside, benciphisa imvamisa yokugcinwa komkhumbi okomile nokusetshenziswa kabusha.
- Ekusetshenzisweni okungokoqobo, opende abazipholishayo basetshenziswa kakhulu ezinhlotsheni ezihlukahlukene zemikhumbi, okuhlanganisa imikhumbi yabahwebi, imikhumbi yempi, nezikebhe. Emikhumbi yabathengisi, ukugcina isikebhe sihlanzekile kunganciphisa ukumelana noseyili futhi kuthuthukise ukusebenza kahle kukaphethiloli, ngaleyo ndlela konga izindleko zokusebenza. Emikhumbini yempi, ukusebenza kahle kokuvikela umkhumbi kusiza ukuqinisekisa isivinini sokuhamba nokunyakaza komkhumbi futhi kuthuthukisa ukusebenza kahle kokulwa. Kuma-yachts, ingagcina ukubukeka kwe-hull isesimweni esihle ngaso sonke isikhathi futhi ithuthukise ubuhle.
- Ngokukhula kwezidingo eziqinile zokuvikela imvelo, opende abazipholishayo nabo bahlala bethuthuka futhi benza izinto ezintsha. Abasebenzi bakwa-R & D bazibophezele ekwehliseni ukusetshenziswa kwezithasiselo ezinobuthi be-biologically kubo kuyilapho bethuthukisa ukusebenza kukapende ongangcolisi ukuze bathole umphumela wokungangcolisi imvelo kakhudlwana nosebenza ngempumelelo. Abanye opende abasha abazipholishayo abazipholishayo basebenzisa ubuchwepheshe be-nanotechnology ukuze bathuthukise ikhono labo lokungangcolisi kanye nokusebenza kokuzipholisha ngokushintsha ukwakheka kwe-microscopic yokunamathela. Ngokuzayo, opende abazipholishayo abazipholishayo kulindeleke ukuthi badlale indima enkulu emkhakheni wobunjiniyela basolwandle futhi banikeze ukwesekwa okuqinile ekuthuthukisweni kwemboni yasolwandle.
Izici eziyinhloko
Vimbela izinto eziphilayo zasolwandle ukuthi zingabangeli umonakalo ngaphansi komkhumbi, ugcine okungaphansi kuhlanzekile; Yenza ukupholishwa ngokuzenzakalela nangokushesha ukuze unciphise ukuhwalala kwephansi lomkhumbi, ngomphumela omuhle wokunciphisa ukudonsa; Ayiqukethe izibulala-zinambuzane ezisekelwe ku-organotin, futhi ayinangozi endaweni yasolwandle.
indawo yohlelo lokusebenza
Isetshenziselwa izingxenye ezingaphansi kwamanzi ngaphansi komkhumbi kanye nezakhiwo zasolwandle, ivimbela izinto eziphilayo zasolwandle ukuthi zinganamatheli. Ingasetshenziswa njengopende wokulungisa omelene nokungcoliswa phansi kwemikhumbi esebenza ngokuzulazula komhlaba wonke kanye ne-berthing yesikhashana.

Izidingo Zobuchwepheshe
- Ukwelashwa okungaphezulu: Zonke izindawo kufanele zihlanzeke, zome futhi zingangcoli. Kufanele zihlolwe futhi ziphathwe ngokuhambisana ne-ISO8504.
- Izindawo ezimbozwe ngopende: Izimbozo ezihlanzekile, ezomile neziqinile. Sicela uxhumane nomnyango wezobuchwepheshe wesikhungo sethu.
- Ukunakekela: Izindawo ezigqwalile, eziphathwa ngejethi lamanzi elinomfutho ophezulu kakhulu ukuya ezingeni le-WJ2 (NACENo.5/SSPC Sp12) noma ngokuhlanza amathuluzi kagesi, okungenani ileveli ye-St2.
- Ezinye izindawo: Lo mkhiqizo usetshenziselwa amanye ama-substrates. Sicela uxhumane nomnyango wezobuchwepheshe wesikhungo sethu.
- Opende abahambisanayo bangemva kokufaka isicelo: Iziqalo zochungechunge lwezinki ezincibilika emanzini, ezincibilika emanzini, iziqalo ezinothe nge-epoxy zinc, iziqalo zokulwa nokugqwala kwendawo ephansi, ukukhishwa okukhethekile kokugqwala kanye nopende bokugqwala, iziqalo ze-phosphate zinc, opende be-epoxy iron oxide zinc anti-rust, njll.
- Amapende afanayo angemuva kwesicelo: Abekho.
- Izimo zokwakha: Izinga lokushisa elingaphansi komhlaba akufanele libe ngaphansi kuka-0℃, futhi okungenani libe ngu-3℃ ngaphezu kwezinga lokushisa lendawo yamazolo (izinga lokushisa kanye nomswakama ohlobene kufanele kukalwe eduze nendawo engaphansi). Ngokuvamile, umoya omuhle uyadingeka ukuze kuqinisekiswe ukomiswa okuvamile kopende.
- Izindlela zokwakha: Fafaza ukupenda: Ukufafaza okungenamoya noma ukufutha ngomoya. Kunconywa ukusebenzisa isifutho esingenamoya esinomfutho ophezulu. Uma usebenzisa isifutho esisizwa umoya, ukunakwa kufanele kukhokhwe ekulungiseni i-viscosity kapende nokucindezela komoya. Inani le-thinner akufanele lidlule i-10%, ngaphandle kwalokho lizothinta ukusebenza kokugqoka.
- Ukudweba kwebhulashi: Kunconywa ukuthi kusetshenziswe ku-pre-coating kanye nomdwebo wendawo encane, kodwa kufanele kufinyelele ubukhulu befilimu eyomile ecacisiwe.
Amanothi Okunakwa
Le ngxube iqukethe izinhlayiya ze-pigment, ngakho-ke kufanele ixutshwe kahle futhi inyakaze ngaphambi kokusetshenziswa. Ugqinsi lwefilimu kapende elimelene nokungcoliswa kunomthelela obalulekile kumphumela wokulwa nokungcolisa. Ngakho-ke, inani lezendlalelo zokugqoka alikwazi ukuncishiswa futhi i-solvent akufanele ifakwe ngokungahleliwe ukuze kuqinisekiswe ubukhulu befilimu yepende. Impilo Nokuphepha: Sicela unake izimpawu eziyisixwayiso esitsheni sokupakisha. Sebenzisa endaweni enomoya omuhle. Ungahogeli inkungu kapende futhi ugweme ukuthintana kwesikhumba. Uma upende usakazeka esikhumbeni, hlambulula ngokushesha nge-ejenti yokuhlanza efanelekile, insipho namanzi. Uma sichaphazela emehlweni, hlambulula ngamanzi amaningi futhi ufune ukwelashwa ngokushesha.
