Isingeniso:
I-Roller Coating isibe yindlela ekhethwayo yokufaka izigqoko kumakhoyili we-aluminium ngenxa yokusebenza kwayo kanye nokusebenza kahle. Ngokufunwa okwandayo kwemikhiqizo ye-aluminium esezingeni eliphakeme futhi eqinile, i-roller coating isibe inqubo ebalulekile embonini ye-aluminium. Kodwa-ke, ukuze uzuze imiphumela oyifunayo, kubalulekile ukuqonda izidingo ezithile zokusebenza kwe-roller coating. Kule bhulogi, sizokwelulela ezimfuneko zokusebenza ezisemqoka ama-roller coating agezeli kufanele afeze, agxile ekuboneni nasekuveleni izakhiwo, ukwelashwa okusheshayo, izici zokuhlobisa, kanye nokumelana nesimo sezulu.
1. I-viscosity efanelekile kanye nezakhiwo ezinhle kakhulu:
Inqubo ye-Roller Coating ifaka ukufundwa kwebhande okusheshayo, ukuhlanganiswa kwe-roller, ukubhaka okuphezulu okushisa okuphezulu, nokupholisa okusheshayo. Ukuqinisekisa izakhiwo ezisezingeni elifanele, kubalulekile ukuze i-roller ye-coating isebenzise inani elanele lopende ezintweni ze-aluminium. Ngakho-ke, izigqoko zokugoqwa kwe-roller coating kumele zibe nokubonakala okufanelekile kanye nezakhiwo ezinhle kakhulu. I-viscosity ye-coating kufanele yenziwe ngokucophelela ukuvumela uhlelo lokusebenza olulula ngenkathi kugcinwa amandla alo okulinganisa ngokulinganayo endaweni ye-aluminium. Ukuthola ibhalansi efanelekile ye-viscosity kubalulekile ekuvikeleni izindaba ezinjengokuqina kokuhlanganiswa okungekho emthethweni, ama-streaks, nemiphumela ye-orange peec.
2. Ukwelapha okusheshayo:
Ngenxa yesimo esisheshayo se-Roller Coating Proating Lines, i-Purling esheshayo isidingo esibucayi se-roller coating coatings. Ngaphandle kokuxhaswa kanye nobude obulinganiselwe be-oveni yokubhaka, isikhathi esitholakalayo sopende sokwelashwa sincishiswa kakhulu. I-Paints esetshenziswe ku-roller coating kumele yenzelwe ukwelapha kungakapheli isikhathi esifushane, mhlawumbe ngaphansi kwemizuzwana engama-60. Ngaphezu kwalokho, inqubo yokulapha kufanele igcine upende ngaphansi kokushisa kwamakhoyili ka-260°C ukuvikela impahla ekuguqukeni noma kwezinye izindlela ezingezinhle. Ukukhetha okulungile kwe-solvent kuyadingeka ukufezekisa ukwelashwa okusheshayo ngaphandle kokuyekethisa ubuqotho be-coating, ukugwema izindaba ezijwayelekile njengokuthi bubbling, ama-mainholes, kanye nokunciphisa izinga.
3. Izici zokuhlobisa:
Ngaphandle kwezindawo ezisebenzayo, izigqoko zokuhlanganisa ze-roller kumele futhi zihlangabezane nezidingo zokuhlobisa. I-Polyester Paint ivame ukwanele ukufeza ukubukeka okufiselekayo ngohlelo lokusebenza olulodwa. Kodwa-ke, lapho usebenzisa i-Fluorocarbon Coating, i-primer ne-topcoat iyadingeka ukuthola imiphumela yokuhlobisa efanele. I-Primer kufanele ibe nokumelana nokukhulumisana okuhle kakhulu nokunamathelisa kuzo zombili i-substrate kanye ne-topcoat, kuyilapho i-topcoat kufanele ibonise amandla amahle okuhlamba kanye nezakhiwo zokuhlobisa. Ijazi elilodwa le-Primer elilandelwa ijazi elilodwa le-topcoat lingaholela ekubonakaleni okuhle okuhlangabezana nakho zombili izidingo zobuhle nezisebenzayo.
4. Ukumelana Nesimo Sezulu:
Imidwebo ye-roller coating kufanele ikhombise ukumelana kwesimo sezulu okuhlukile, ikakhulukazi uma isetshenziswa kumikhiqizo yangaphandle ye-aluminium. I-PVDF Fluococarbon Broorangs isetshenziselwa ukuhlinzeka ngokusebenza okuphelele okuphikisana nezici ezinjengokuqina, imvula ye-acid, ukungcoliswa komoya, ukugcwala, amabala emile, nokuma, amabala emile, nokuma, amabala emile, nokuma, amabala amile, amabala amile, amabala amile, amabala amile kanye nokubumba. Ngokuya ngezidingo ezithile zendawo, ezimbili, ezintathu, noma amajazi amane we-PVDF Coating angasetshenziswa. Lokhu kuqinisekisa ukuvikelwa okuhlala isikhathi eside kanye nokuqina okuphezulu, okuvumela ikhoyili ye-aluminium ehlanganisiwe ukumelana nezimo zemvelo ezinzima kakhulu.
Isiphetho:
Ekuphetheni, ukuzuza ukusebenza okuhlukile kwe-roller coating ye-aluminium kudinga ukucubungula ngokucophelela ukubonwa kwendawo yokuhlanganisa kanye nokulinganisa izakhiwo, amakhono okuqondisa asheshayo, amandla okuhlobisa, kanye nokumelana kwesimo sezulu. Ngokuqonda nangokunamathela kulezi zidingo zokusebenza, abakhiqizi bangakhiqiza imikhiqizo esezingeni eliphakeme le-aluminium ehlangabezana namazinga afunayo ezimboni ezahlukahlukene. Njengokufunwa kwe-aluminium coils enokwethenjelwa futhi ebonakalayo kuyaqhubeka ukukhula, kubalulekile ukubeka phambili ukukhetha nokusetshenziswa kwezingubo zokugoqa ze-roller coating ezingafeza lezi zidingo ezibalulekile zokusebenza.
