Ukuhlangabezana neemfuno ezithile zeeprojekthi ezahlukeneyo, sibonelela ngobugcisa obahlukeneyo bokwambathisa obulungelelaniswe neemeko zemozulu zalapha ekhaya kunye neemfuno zentengiso. Sinikezela ngonyango olulungiselelwe umphezulu kuzo zonke iimveliso zethu, ngokusekwe kukhetho lwabathengi, ngelixa sikwabonelela ngeengcebiso zobuchwephesha.
Anodizing vs. Powder Coating
Itheyibhile ilandelayo ibonisa uthelekiso oluthe ngqo phakathi kwe-anodizing kunye ne-powder coatings njengeenkqubo zokugqiba umphezulu.
| Anodizing | Powder Coating |
| Inokuba bhityile kakhulu, oku kuthetha ukuba utshintsho oluncinci kakhulu kwimilinganiselo yenxalenye. | Unokufezekisa iidyasi ezishinyeneyo, kodwa kunzima kakhulu ukufumana umaleko omncinci. |
| Uluhlu olukhulu lwemibala yentsimbi, enemiphetho egudileyo. | Iindidi ezingaqhelekanga zemibala kunye nemibala zinokufezekiswa. |
| Ngokurisayikilishwa okufanelekileyo kwe-electrolyte, i-anodizing ihambelana kakhulu nokusingqongileyo. | Akukho zinyibilikisi zibandakanyekayo kwinkqubo, nto leyo eyenza ukuba ikhuseleke kakhulu kokusingqongileyo. |
| Ukunxiba okugqwesileyo, ukukrwela, kunye nokumelana nomhlwa. | Ukumelana nokugqwesa okulungileyo ukuba umphezulu ufana kwaye ungonakaliswa. Iyakwazi ukunxiba kunye nokukrwela ngokulula kune-anodizing. |
| Ukumelana nokuncipha kombala okoko nje idayi ekhethiweyo inokumelana ne-UV efanelekileyo kwisicelo kwaye itywinwe ngokufanelekileyo. | Ixhathisa kakhulu ekuphelelweni kombala, nokuba ibekwe kwisibane se-UV. |
| Yenza umphezulu we-aluminiyam ngombane ungaqhubeki. | Enye i-conductivity yombane kwi-coating kodwa ingekho kakuhle njenge-aluminium engenanto. |
| Ingaba yinkqubo ebiza kakhulu. | Ixabisa ngakumbi kune-anodizing. |
I-aluminiyam ngokwendalo iphuhlisa umaleko obhityileyo we-oxide kumphezulu wayo xa ivezwe emoyeni. Lo maleko we-oxide awusebenzi, oku kuthetha ukuba awusasebenzi kunye nokusingqongileyo - kwaye ukhusela isinyithi esiseleyo kwizinto.
Anodizing
I-Anodizing lunyango lomphezulu lwamalungu e-aluminiyam athatha ithuba lomaleko we-oxide ngokuwujiya. Amagcisa athatha isiqwenga se-aluminium, njengenxalenye ekhutshiweyo, ayifake kwibhafu ye-electrolytic, kwaye aqhube umsinga wombane ngayo.
Ngokusebenzisa i-aluminium njenge-anode kwisekethe, inkqubo ye-oxidation iyenzeka kumphezulu wesinyithi. Idala umaleko weoksidi ojiyileyo kunalowo wendalo.
Ukugquma umgubo
Ukufakwa kwepowder yolunye uhlobo lwenkqubo yokugqiba esetyenziswa kwiintlobo ezininzi zeemveliso zetsimbi. Le nkqubo iphumela kwinqanaba elikhuselayo kunye nokuhlobisa kumphezulu wemveliso ephathwayo.
Ngokungafaniyo nezinye izicelo zokugquma (umzekelo, ukupeyinta), ukugquma komgubo yinkqubo yokufaka eyomileyo. Akukho zinyibilikisi zisetyenziswayo, ukwenza ukugquma komgubo kube yindlela ehambelana nokusingqongileyo kunolunye unyango lokugqiba.
Emva kokucoca inxalenye, uchwepheshe usebenzisa i powder ngoncedo lwesibhamu sokutshiza. Lo mpu usebenzisa intlawulo embi ye-electrostatic kumgubo, eyenza ukuba itsaleleke kwinxalenye yentsimbi esekelwe phantsi. Umgubo uhlala uncanyathiselwe kwinto ngelixa uphiliswa kwi-oveni, ukuguqula idyasi yomgubo ibe yiyunifomu, umaleko oqinileyo.
Iingubo zePVDF
Iingubo ze-PVDF zifanelekile phakathi kweentsapho ze-fluorocarbon zeplastiki, ezenza iibhondi ezizinzile kakhulu ngokwekhemikhali kunye ne-thermal. Oku kwenza ukuba ezinye zezinto eziguquguqukayo zokwaleka ze-PVDF zikwazi ukuhlangabezana ngokuthe gqolo okanye zigqithe kwiimfuno ezingqongqo (ezifana ne-AAMA 2605) ngokuphela okuncinci ixesha elide. Usenokuba uyazibuza ukuba ezi ngubo zifakwa njani.
Inkqubo yesicelo sePVDF
Iingubo ze-PVDF ze-aluminiyam zisetyenziswa kwindawo yokupeyinta ngompu wokutshiza olwelo. La manyathelo alandelayo achaza inkqubo epheleleyo yokugqiba umgangatho ophezulu we-PVDF yokwambathisa:
- Ukulungiswa komphezulu– Naluphi na ukwambatha olukumgangatho ophezulu lufuna ukulungiswa kakuhle komphezulu. I-PVDF efanelekileyo yokunamathela kwi-coating ifuna ukucocwa, ukucocwa, kunye ne-deoxidizing (ukususa umhlwa) umphezulu we-aluminium. Iingubo eziphezulu ze-PVDF ke zifuna ukusetyenziswa kwe-chrome-based conversion coating ukuba isetyenziswe phambi kwe-primer.
- Iprimer- I-primer iyazinzisa ngokufanelekileyo kwaye ikhusela ubuso besinyithi ngelixa iphucula ukunamathela kwi-coating top.
- PVDF Top Coating- Umbala we-pigment particles zongezwa kunye nokusetyenziswa kwengubo ephezulu. Ingubo ephezulu isebenza ukubonelela ngokuchasana nomonakalo ukusuka ekukhanyeni kwelanga kunye namanzi, kunye nokunyuka kokuxhatshazwa kwe-abrasion. Ukwaleka kufuneka kuphiliswe emva kweli nyathelo. Umphezulu wokwaleka lolona maleko ngqindilili kwinkqubo yokwambathisa yePVDF.
- I-PVDF ecacileyo yoKutyabeka- Kwinkqubo yokugqoka i-PVDF ye-3-layer, i-layer yokugqibela yi-coat ecacileyo, enika ukhuseleko olongezelelweyo kwindalo kwaye ivumela umbala we-topcoat ngaphandle kokuwubonakalisa umonakalo. Lo maleko wokugquma kufuneka unyangwe.
Ukuba kuyimfuneko kwizicelo ezithile, i-2-coat okanye i-4-coat process ingasetyenziswa endaweni ye-3-coat method echazwe ngasentla.
IiNzuzo eziPhambili zokuSebenzisa iPVDF yoKutyabeka
- Ikhuseleke ngakumbi kokusingqongileyo kuneengubo zokudipha, eziqulethe iikhompawundi eziguquguqukayo eziphilayo (VOCs)
- Ukumelana nokukhanya kwelanga
- Ukuxhathisa kwi-corrosion kunye ne-chalking
- Ukumelana nokunxiba kunye nokukrazula
- Igcina umbala ophezulu wokungaguquguquki (uxhathisa ukubuna)
- Ukuxhathisa okuphezulu kwiikhemikhali kunye nongcoliseko
- Ihlala ixesha elide kunye nokugcinwa okuncinci
Ukuthelekisa iPVDF kunye nePowder Coatings
Owona mahluko uphambili phakathi kwePVDF yokwambathisa kunye nomgubo wokutyabeka kukuba iPVDF ityabeka:
- Sebenzisa ipeyinti yolwelo emodareyithiweyo, ngelixa umgubo wokwaleka usebenzisa umgubo ofakwe kwi-electrostatically
- Zincinci kuneengubo zomgubo
- Inokunyangwa kwiqondo lobushushu begumbi, ngelixa umgubo kufuneka ubhakwe
- Ziyakwazi ukumelana nokukhanya kwelanga (imitha ye-UV), ngelixa iingubo zomgubo ziya kuphela ngokuhamba kwexesha ukuba zibonakalisiwe
- Inokuba nesiphelo sematte kuphela, ngelixa iingubo zomgubo zinokuza kuluhlu olupheleleyo lwemibala kunye nokugqitywa
- Zixabisa kakhulu kuneengubo zomgubo, ezinexabiso eliphantsi kwaye zinokonga iindleko ezongezelelweyo ngokuphinda usebenzise umgubo otshizwe ngaphezulu.
Ngaba kufuneka Ndinxibe iAluminiyam yeZakhiwo ngePVDF?
Inokuxhomekeka kwizicelo zakho ezichanekileyo kodwa ukuba ufuna ukuhlala ixesha elide, ukumelana nokusingqongileyo, kunye nemveliso ye-aluminium ehlala ixesha elide okanye eqengqelekayo, iingubo ze-PVDF zingakulungela.
