Kuwononga zachilengedwe zam'madzi kumatha kuwononga zida zauinjiniya zam'madzi, kuchepetsa moyo wantchito wazinthu, ndikuwononga kwambiri zachuma komanso ngozi zoopsa.Kugwiritsa ntchito zokutira zotsutsa ndi njira yothetsera vutoli.Pamene mayiko padziko lonse lapansi akuyang'ana kwambiri chitetezo cha chilengedwe, nthawi yoletsa kuletsa kugwiritsa ntchito organotin antifouling agents yakhala nthawi yotsimikizika.Kupanga zida zatsopano komanso zogwira ntchito zowononga tizilombo toyambitsa matenda komanso kugwiritsa ntchito mankhwala oletsa tizilombo toyambitsa matenda a nano-level akhala chinthu chofunika kwambiri kwa akatswiri ofufuza utoto wapanyanja m'mayiko osiyanasiyana.

 1) Titaniyamu mndandanda nano anticorrosive ❖ kuyanika

 a) Nano zipangizo monganano titanium dioxidendinano zinc oxidezomwe zimagwiritsidwa ntchito mu titaniyamu nano anticorrosive zokutira zitha kugwiritsidwa ntchito ngati antibacterial agents omwe alibe poizoni m'thupi la munthu, amakhala ndi antibacterial osiyanasiyana osiyanasiyana, komanso amakhala ndi kukhazikika kwabwino kwamatenthedwe.Zida zopanda zitsulo ndi zokutira zomwe zimagwiritsidwa ntchito m'mabwalo a sitima zapamadzi nthawi zambiri zimakhala ndi chinyezi komanso malo ang'onoang'ono m'malo omwe amaipitsidwa mosavuta, makamaka m'madera otentha komanso otentha a m'nyanja, ndipo amakhudzidwa kwambiri ndi kukula kwa nkhungu ndi kuipitsa.The antibacterial zotsatira za nanomaterials angagwiritsidwe ntchito kukonzekera zatsopano ndi kothandiza antibacterial ndi antifungal zipangizo ndi zokutira mu kanyumba.

 b) Nano titaniyamu ufa ngati chodzaza inorganic amatha kukonza makina ndi kukana dzimbiri kwa epoxy resin.Ufa wa nano-titaniyamu womwe umagwiritsidwa ntchito poyesera uli ndi tinthu tating'ono tochepera 100nm.Zotsatira zoyesa zikuwonetsa kuti kukana kwa dzimbiri kwa epoxy-modified nano-titanium powder coating ndi polyamide-modified nano-titanium powder coating zasinthidwa ndi 1-2 Magnitude.Konzani kusintha kwa epoxy resin ndi kubalalitsidwa.Onjezani 1% yosinthidwa nano titaniyamu ufa ku epoxy resin kuti mupeze zosinthidwa za nano titaniyamu ufa.Zotsatira za mayeso a EIS zikuwonetsa kuti impedance modulus ya otsika pafupipafupi kumapeto kwa zokutira imakhalabe pa 10-9Ω.cm ~ 2 pambuyo pa kumizidwa kwa 1200h.Ndi maoda a 3 apamwamba kuposa epoxy varnish.

 2) Nano zinc oxide

 Nano-ZnO ndi chinthu chokhala ndi zinthu zambiri zabwino kwambiri ndipo chagwiritsidwa ntchito kwambiri m'magawo ambiri.Ili ndi antibacterial properties motsutsana ndi mabakiteriya.Titanate coupling agent HW201 itha kugwiritsidwa ntchito kusinthira pamwamba pa nano-ZnO.Zosinthidwa za nano-matadium zimagwiritsidwa ntchito ngati zodzaza mu epoxy resin coating system kukonza mitundu itatu ya zokutira za nano-marine antifouling zokhala ndi bakiteriya.Kupyolera mu kafukufuku, apeza kuti dispersibility wa kusinthidwa nano-ZnO, CNT ndi graphene wakhala kwambiri bwino.

 3) ma nanomatadium opangidwa ndi kaboni

      Mpweya wa carbon nanotubes (CNT)ndi graphene, monga zinthu akutuluka carbon-based, ndi katundu kwambiri, si poizoni, ndipo saipitsa chilengedwe.Onse CNT ndi graphene ndi bactericidal katundu, ndipo CNT akhoza kuchepetsa enieni pamwamba mphamvu ❖ kuyanika.Gwiritsani ntchito silane coupling agent KH602 kuti musinthe pamwamba pa CNT ndi graphene kuti apititse patsogolo kukhazikika kwawo komanso kufalikira mu makina opaka.Zida zosinthidwazo zidagwiritsidwa ntchito ngati zodzaza kuti ziphatikizidwe mu makina opaka utomoni wa epoxy kukonza mitundu itatu ya zokutira za nano-Marine antifouling zokhala ndi bactericidal effect.Kupyolera mu kafukufuku, apeza kuti dispersibility wa kusinthidwa nano-ZnO, CNT ndi graphene wakhala kwambiri bwino.

4) Anticorrosive ndi antibacterial chipolopolo pachimake nanomaterials

Kugwiritsa ntchito antibacterial katundu wapamwamba kwambiri wa siliva ndi mawonekedwe a porous chipolopolo cha silika, kamangidwe ndi kamangidwe ka pachimake-chipolopolo chopangidwa nano Ag-SiO2;kafukufuku pamaziko ake bactericidal kinetics, bactericidal limagwirira ndi ntchito odana dzimbiri, pakati pa siliva pachimake kukula ndi 20nm, makulidwe a nano-silika chipolopolo wosanjikiza pafupifupi 20-30nm, zotsatira antibacterial ndi zoonekeratu. mtengo wogwira ntchito ndi wapamwamba.

 5) Nano cuprous oxide antifouling zakuthupi

      Cuprous oxide CU2Ondi antifouling wothandizira ndi mbiri yaitali ntchito.Kutulutsa kwa nano-size cuprous oxide ndikokhazikika, komwe kumatha kupititsa patsogolo ntchito ya antifouling ya zokutira.Ndi zokutira zabwino zotsutsana ndi dzimbiri za zombo.Akatswiri ena amaneneratu kuti nano cuprous oxide akhoza Kuchita zochizira organic zoipitsa chilengedwe.
