Isingeniso:
I-roller coating sekuyiyona ndlela ekhethwayo yokusebenzisa izimbotshana kumakhoyili e-aluminium ngenxa yokusebenza kahle kwayo nokusebenza kwayo. Ngokukhula kwesidingo semikhiqizo ye-aluminium enombala ophakeme futhi ehlala isikhathi eside, ukufakwa kwama-roller sekuphenduke inqubo ebalulekile embonini ye-aluminium. Kodwa-ke, ukuze uzuze imiphumela oyifunayo, kubalulekile ukuqonda izidingo ezithile zokusebenza ze-roller coating. Kule bhulogi, sizocubungula izidingo ezibalulekile zokusebenza okufanele zifezwe yizingubo zokumboza, sigxile ku-viscosity kanye nezakhiwo zokulinganisa, ukuphulukiswa okusheshayo, izici zokuhlobisa, kanye nokumelana nesimo sezulu.
1. I-viscosity efanele kanye nezakhiwo ezinhle zokulinganisa:
Inqubo yokumboza i-roller ihilela ukuphakelwa kwebhande okusheshayo, ukumbozwa nge-roller, ukubhaka okuphezulu kwezinga lokushisa, nokupholisa ngokushesha. Ukuqinisekisa izakhiwo ezisezingeni elifanele, kubalulekile ukuthi i-roller yokugqoka ifake inani elanele lopende ezintweni ze-aluminium. Ngakho-ke, i-roller coating coating kufanele ibe ne-viscosity efanele kanye nezakhiwo ezinhle zokulinganisa. I-viscosity ye-coating kufanele yenziwe ngokucophelela ukuvumela ukusetshenziswa okulula ngenkathi igcina ikhono layo lokukala ngokulinganayo endaweni ye-aluminium. Ukufinyelela ibhalansi ye-viscosity efanele kubalulekile ekuvimbeleni izinkinga ezifana nokushuba okungalingani, ama-streaks, nemiphumela yekhasi elolintshi.
2. Ukwelashwa ngokushesha:
Ngenxa yemvelo esheshayo yemigqa yokukhiqiza i-roller coating, ukuphulukiswa okusheshayo kuyisidingo esibalulekile sezingubo zokumboza ama-roller. Ngaphandle kokusekelwa kanye nobude obulinganiselwe behhavini yokubhaka, isikhathi esitholakalayo sokuthi upende welashwe sincishiswe kakhulu. Opende abasetshenziswa ekuhlanganisweni kwe-roller kufanele bakhiwe ukuze belaphe phakathi nesikhashana esifushane, okungcono kakhulu ngaphansi kwamasekhondi angu-60. Ukwengeza, inqubo yokwelapha kufanele igcine upende ungaphansi kwezinga lokushisa lekhoyili elingu-260°C ukuvimbela okokusebenza ekuguquguqukeni noma okunye ukusabela okungekuhle. Ukukhetha okuncibilikisayo okulungile kuyadingeka ukuze kutholakale ukwelashwa ngokushesha ngaphandle kokulimaza ubuqotho be-coating, ukugwema izinkinga ezivamile ezifana nokubhamuza, ama-pinnholes, nokungalinganisi kahle.
3. Izici zokuhlobisa:
Ngaphandle kwezakhiwo ezisebenzayo, ukugqoka kwe-roller kufanele futhi kuhlangabezane nezidingo zokuhlobisa. Upende we-polyester uvame ukwanele ukufeza ukubukeka okufunayo ngohlelo lokusebenza olulodwa. Kodwa-ke, uma usebenzisa i-fluorocarbon coating, i-primer ne-topcoat iyadingeka ukuze uthole imiphumela emihle yokuhlobisa. I-primer kufanele ibe nokuvikeleka okuhle kakhulu kokugqwala nokunamathela kukho kokubili i-substrate nejazi eliphezulu, kuyilapho ijazi eliphezulu kufanele libonise amandla amahle okucasha kanye nezakhiwo zokuhlobisa. Ijazi elilodwa le-primer elilandelwa yijazi elilodwa le-topcoat lingabangela ukubukeka okuhle okuhlangabezana kokubili nezidingo zobuhle nokusebenza.
4. Ukumelana nesimo sezulu:
Izingubo zokumboza ngama-roller kufanele zibonise ukumelana nesimo sezulu, ikakhulukazi uma zisetshenziswa emikhiqizweni ye-aluminium yangaphandle. Izingubo ze-PVDF ze-fluorocarbon zivame ukusetshenziselwa ukunikeza ukusebenza okuphelele ngokumelene nezici ezifana nokuqina, imvula ene-asidi, ukungcoliswa komoya, ukugqwala, amabala amile, kanye nesikhunta. Ngokuya ngezidingo ezithile zendawo, amajazi amabili, amathathu, noma amane e-PVDF angasetshenziswa. Lokhu kuqinisekisa ukuvikeleka okuhlala isikhathi eside kanye nokuqina okukhulu, okuvumela ikhoyili ye-aluminium eboshiwe ukuthi imelane ngisho nezimo zemvelo ezinzima kakhulu.
Isiphetho:
Sengiphetha, ukufeza ukusebenza okukhethekile kokumboza amakhoyili e-aluminum kudinga ukucatshangelwa ngokucophelela kwe-viscosity ye-coating kanye nezakhiwo zokulinganisa, amandla okwelapha okusheshayo, izici zokuhlobisa, kanye nokumelana nesimo sezulu. Ngokuqonda nokunamathela kulezi zidingo zokusebenza, abakhiqizi bangakhiqiza imikhiqizo ye-aluminium ehlanganiswe nekhwalithi ephezulu ehlangabezana nezindinganiso ezidingekayo zezimboni ezihlukahlukene. Njengoba isidingo samakhoyili e-aluminium anokwethenjelwa futhi abukeka ekhangayo siqhubeka sikhula, kubalulekile ukubeka phambili ukukhethwa kanye nokusetshenziswa kwamakhoyili angama-roller angafeza lezi zidingo ezibalulekile zokusebenza.
