Colour coated board ndeye yakasvibira uye ine hushamwari hwekuvakisa.Nzira yekuisarudza nemazvo, kuishandisa zvine musoro, uye kugadzirisa hupenyu hwayo hwesevhisi ndiyo inonyanya kunetsa kune varidzi uye vavaki veinjiniya.Baosteel, sechinhu chakazara chesimbi chirimwa, ine ruzivo rwakapfuma mukugadzira uye kushandiswa kwemavara akavharwa mahwendefa.Iyo "Scientific Material Selection" module inopa kurudziro pfupi uye sumo kune vashandisi pakusarudza uye kushandiswa kwemavara akavharwa mahwendefa.
Sarudzo chaiyo yemavara akaputirwa mapaneru anofanirwa kufunga nezve yakasikwa nharaunda, nharaunda yekushandisa, dhizaini hupenyu, uye chimiro chechimiro chechivako, kuitira kuti usarudze rudzi rwesimbi, dhizaini, bhandi, uye coating inofanana nayo.Vagadziri vezvivakwa, varidzi veinjiniya, uye ma processor anofunga nezve kuchengetedzwa kwekuita (kukanganisa kupikisa, seismic kuramba, moto kuramba, mhepo inomanikidza kuramba, chando kuramba), kuita kwekugara (kusapinda mvura, kuvharira ruzha, kuvharira), kusimba (kuramba kusvibiswa, kusimba, kuchengetedza chitarisiko) , uye hupfumi (mutengo wakaderera, kugadzirisa nyore, kugadzirisa kuri nyore, uye kutsiva nyore) kwezvivakwa.Kune vatengesi vemavara akavharwa mahwendefa esimbi, zvivakwa izvi zvinofanirwa kushandurwa kuita mavara akavharidzirwa simbi ndiro zvivakwa nesimbi zvigayo uye zvakavimbiswa.Izvo zvinodikanwa zvekushanda kwemavara akavharidzirwa mahwendefa esimbi anonyanya zvinosanganisira michina yemidziyo (simba rekusimba, simba regoho, kurebesa), kuita kwekuvhara (rudzi rwekuputira, ukobvu hwekuputira, uye kunamatira kwekupfeka), uye kuita kwekuvhara (rudzi rwekupfeka, ruvara, gloss). , durability, processability, etc.).Pakati pazvo, kuramba kwemhepo, kuramba kwemhepo, kuramba kwechando, kuramba kwekudengenyeka kwenyika, nezvimwe zvese zvine chekuita nemagetsi emidziyo, uyezve, zvine hukama kune waveform, ukobvu, span, uye nzvimbo yemarata ane mavara ane mavara. .Kana mahwendefa esimbi ane mavara akakodzera akasarudzwa uye akasanganiswa neakakodzera profiled simbi dhizaini dhizaini, haingogone kusangana nekuchengetedza kwezvivakwa asiwo kuderedza mari yeinjiniya.Kusimba, kuita kwekugadzirisa, uye kuchengetedzwa kwechitarisiko kwezvinhu zvinonyanya kutariswa nekusimba kwemachira uye machira.
Coating zvakasiyana-siyana
Parizvino, mhando dzemachira anoshandiswa kune mavara akavharidzirwa simbi mahwendefa anosanganisira polyester coating (PE), fluorocarbon coating (PVDF), silicon modified coating (SMP), high weather resistance coating (HDP), acrylic acid coating, polyurethane coating (PU) , plastiki sol coating (PVC), nezvimwewo.
Yakajairika polyester (PE, Polyester)
PE coating ine yakanaka kunamatira kune zvinhu, uye mavara akavharidzirwa simbi mahwendefa ari nyore kugadzira uye kuumba, anodhura-zvinoshanda, uye ane akawanda ezvigadzirwa.Pane zvakawanda zvingasarudzwa zvemavara uye gloss.Pasi pekutarisa zvakananga kune zvakajairwa zvakatipoteredza, hupenyu hwayo hunopesana nekuora hunogona kusvika kumakore 7-8.Nekudaro, munzvimbo dzeindasitiri kana nzvimbo dzakasvibiswa zvakanyanya, hupenyu hwayo hwebasa huchadzikiswa.Nekudaro, machira epolyester haana kunaka kune UV kuramba uye firimu poda kuramba.Naizvozvo, kushandiswa kwePE machira kuchiri kudikanwa kushomeka, uye anowanzo shandiswa munzvimbo dzine kushomeka kwemhepo kusvibiswa kana zvigadzirwa zvinoda kuumbwa kwakawanda uye kugadzirisa.
Silicone Yakagadziridzwa Polyester (SMP)
Nekuda kwekuvapo kweanoshanda mapoka - OH/- COOH mupolyester, zviri nyore kuita nemamwe mapolymer uye zvinhu.Kuti uvandudze kupikisa kwezuva uye pulverization yePE, silicone resin ine yakanakisa kuchengetedza kwemavara uye kupisa kwekudzivirira inoshandiswa pakuita denaturation.The denaturation reshiyo nePE inogona kuva pakati pe5% ne50%.SMP inopa kusimba kuri nani kwemahwendefa esimbi, nehupenyu hwekuramba hwekuora hunosvika makore gumi kusvika gumi nemaviri.Ehezve, mutengo wayo wakakwira zvakare kupfuura iwo wePE, Zvisinei, nekuda kwekusagutsikana kunamatira uye kugadzirisa formability yeSilicone resin kune zvinhu, SMP mavara akavharidzirwa simbi mahwendefa haakodzere mamiriro anoda akawanda maitiro ekuumba, uye anonyanya kushandiswa kuvaka matenga nemadziro ekunze.
High weather resistant polyester (HDP, High durable polyester)
Nezve zvikanganiso zvePE neSMP, kambani yeBritish HYDRA (yava kuwanikwa neBASF) nekambani yekuSweden BECKER yakagadzira HDP polyester coatings mukutanga kwa2000 iyo inogona kuwana 60-80% yemamiriro ekunze kuramba kune PVDF machira, uye ari pamusoro kune akajairwa silicon akagadziridzwa polyester machira. .Kuramba kwavo kwekunze kwekunze kunosvika makore gumi nemashanu.Yakakwira mamiriro ekunze inodzivirira polyester resin inogadzirwa uchishandisa monomers ine cyclohexane chimiro kuti uwane chiyero pakati pekushanduka, kuramba mamiriro ekunze, uye mutengo.Inonhuhwirira yemahara polyols uye asidhi inoshandiswa kuderedza kunyura kweUV mwenje neresin, kuwana yakakwirira yemamiriro ekunze kuramba kwejasi.Kuwedzerwa kwema ultraviolet absorbers uye steric hindrance amines (HALS) mufomu yekuputira inovandudza kumira kwemamiriro ekunze kwefirimu repende.Yakakwira yemamiriro ekunze inodzivirira polyester coil coil yakazivikanwa nemusika kunze kwenyika, uye mutengo wayo wakanyanya kunaka.
PVC Plastisol
PVC resin ine mvura yakanaka inodzivirira uye inodzivirira kemikari, uye inowanzoputirwa nepamusoro-soro, nehupamhi hwekuputira hwe 100-300 μ Pakati pe m, inogona kupa yakapfava PVC kupfekedza kana mwenje embossing kurapwa se embossing coating;Nekuda kwekuti PVC coating is thermoplastic resin ine yakakwirira firimu ukobvu, inogona kupa chengetedzo yakanaka yemarata esimbi.Asi PVC ine kusimba kushoma kupisa.Mumazuva ekutanga, yaishandiswa zvakanyanya muEurope, asi nekuda kwekushomeka kwayo kwezvakatipoteredza zvimiro, parizvino iri kushandiswa zvishoma uye zvishoma.
PVDF fluorocarbon
Nekuda kwesimba rakasimba rekubatanidza pakati pemakemikari zvisungo zvePVDF, iyo coating ine yakanakisa corrosion kuramba uye kuchengetedza kwemavara.Ndicho chigadzirwa chepamusoro-soro muindasitiri yekuvaka ruvara rwakavharwa simbi ndiro coating, ine hombe molecular huremu uye yakatwasuka bond chimiro.Naizvozvo, kunze kwekupokana kwemakemikari, mechanical properties, UV resistance, uye kupisa kupisa zvakakoshawo
Pakusarudzwa kweprimer, pane zvinhu zviviri zvakakosha.Imwe ndeyekutarisa kunamatira pakati peprimer uye topcoat, pamwe neiyo substrate.Imwe yacho ndeyokuti primer inopa yakawanda yekudzivirira kwehurosi yejasi.Kubva pakuona uku, epoxy resin ndiyo yakanakisa sarudzo.Kana uchifunga kuchinjika uye UV kuramba, polyurethane primer inogona zvakare kusarudzwa.
Kune yekumashure yekupfekedza, yakanyanya kurongeka sarudzo ndeyekusarudza maviri akaturikidzana chimiro, iyo imwe layer yeback primer uye imwe layer yeback topcoat, kana iyo ruvara yakavharwa simbi ndiro iri mune imwechete bhodhi state.Iyo yekutanga uye yepamberi ndeyemhando dzakasiyana, uye jasi repamusoro rinofanira kunge rakajeka (senge chena) polyester.Kana iyo ruvara yakavharwa simbi ndiro iri mune inoumbwa kana sandwich mamiriro, zvakakwana kuti uise layer ye epoxy resin ine yakanakisa adhesion uye corrosion kuramba kumashure.
Parizvino, kune akawanda anoshanda mavara akavharidzirwa mahwendefa esimbi, akadai se antibacterial color coating, anti-static color coating, thermal insulation color coating, self-cleaning color coating, etc. Kugadzirwa kwezvigadzirwa izvi kune chinangwa chekuzadzisa zvinodiwa vashandisi, asi dzimwe nguva hazvigoneke kudzikamisa kumwe kuita kwezvigadzirwa zvine mavara.Naizvozvo, kana vashandisi vakasarudza inoshanda mavara akavharwa simbi mahwendefa, ivo vanofanirwa kuve vakajeka nezve zvavanoda zvechokwadi.
