The coating of mavara-akavharwa nealuminium coils rakakamurwa kuita: polyester-yakavharwa nealuminium coil (PE), fluorocarbon-yakavharwa aluminium coils (PVDF). Iyo polyester yekuputira inogadzirwa nekubheka pamusoro pearuminiyamu ndiro kwenguva yakawanda inogona kuumba yakasimba yakanamatira inoenderera Solid mafirimu ane inodzivirira yekushongedza zvimiro.. Iri anti-UV coating. Iyo polyester resin inogadzirwa neyepamusoro molecular polymer ine ester bond mumaketani makuru, uye alkyd resin inowedzerwa. Iyo ultraviolet absorber inogona kukamurwa kuita matt uye yakakwira-gloss akateedzana zvichienderana nekupenya. Inogona kupa zvigadzirwa zvealuminium zvine mavara ane mavara akapfuma, kupenya kwakanaka uye kutsetseka, pamwe chete nepamusoro pekugadzirwa uye kunzwa, uye inogona zvakare kuwedzera pfungwa yekuisa uye matatu-dimensionality. Inogona kuchengetedza zvinhu zviri pachena kumhepo uye kurwiswa nemwaranzi ye ultraviolet, mhepo, mvura, chando nechando; nekuda kwekusiyana kwekushisa, freeze-thaw cycles, gasi rinoparadza uye ma microorganisms, kupfeka kunogona kuita basa rekudzivirira. Kunyanya yakakodzera kushongedza kwemukati uye mabhodhi ekushambadza.
Fluorocarbon Coated Prepainted Aluminium Coil (PVDF)
Fluorocarbon coatings iPVDF resin, kunyanya zvichireva vinylidene fluoride homopolymers kana copolymers yevinylidene fluoride uye zvimwe zvidiki zvefluorine-ine vinyl monomers.. Iyo kemikari chimiro cheiyo hydrofluoric acid base material inosungirirwa nefluorine/carbon bonds. Iko kugadzikana uye kusimba kweichi chimiro chemakemikari inoita kuti zvimiro zvemuviri zvefluorocarbon coatings zvisiyane neakajairwa machira.. Pamusoro peiyo abrasion kuramba uye kukanganisa kupikisa maererano nema mechanical properties, ine kuita kwakanakisa, kunyanya mumamiriro ekunze akaoma uye munzvimbo, inoratidza kuramba kwenguva refu kupera uye kushorwa kweUV. Mushure mekupisa-kupisa kubika kugadzira firimu, iyo molecular structure yejasi yakasimba uye ine kurwisana kwemamiriro ekunze.
Fluorocarbon coatings inogona kukamurwa kuita echinyakare fluorocarbon coatings uye nano-fluorocarbon coatings zvinoenderana nepamusoro firimu kuumbwa chimiro.. . Vagadziri vehuputi vanovimbisa hupenyu hwesevhisi yejasi kutanga kubva 10 makore, 15 makore kupfuura 20 makore. General coatings akaedzwa uye akaenzaniswa. Iwo masampula akavharidzirwa akaoneswa kune kupisa kwezuva muFlorida, USA, uye kuratidzwa kune yakaoma nharaunda yemhepo yakanyoro uye ine munyu 12 makore, iyo yakanyatsoratidza kugadzikana uye kusimba kwe fluorocarbon coatings. The performance is 30 uye 80 yakakwira kupfuura mamwe machira maviri, uye iyo fluorocarbon coating inovimbisa kushandiswa munzvimbo dzakasiyana dzakaoma.
