Isebenza Kanjani I-Fluidized Bed Powder Coating?
Umbhede omanzi i-powder coating iyinqubo yokumboza i-substrate nge-powder material. Inqubo ihilela ukumisa i-powder impahla emoyeni, ukudala umbhede owuketshezi wempushana ovumela ukumbozwa ngisho kwe-substrate. Kulesi sihloko, sizohlola ukuthi kanjani i-fluidized bed powder coating isebenza.
Inqubo ye-fluidized bed powder coating ingahlukaniswa ibe izingxenye ezinhlanu eziyinhlokoeps: ukulungiswa kwe-substrate, ukufakwa kwempushana, ukushisa kuqala, ukuncibilika nokuphulukisa.
Isinyathelo 1: Ukulungiswa Kwe-substrate Isinyathelo sokuqala enqubweni yokumboza impushana yombhede omanzi ukulungisa i-substrate. Lokhu kuhlanganisa ukuhlanza i-substrate ukuze kukhishwe noma yikuphi ukungcola, amafutha noma okunye ukungcola okungase kuvimbele impushana ekunamatheleni ngendlela efanele. Lesi sinyathelo sibalulekile empumelelweni yenqubo, njengoba noma yikuphi ukungcola ku-substrate kungase kuphazamise ukunamathela nokuqina kwe-coating.
Isinyathelo sesi-2: Ukusetshenziswa Kwempushana Uma i-substrate isihlanzekile futhi yomile, isilungele isinyathelo sokufaka impushana. I-powder material ivamise ukugcinwa ku-hopper noma esitsheni, lapho ibalwa khona kusetshenziswa isisetshenziswa esikhiphayo. Idivayisi yokukhipha ingalungiswa ukuze kulawulwe inani lempushana esetshenziswayo, kuqinisekiswe ukuthi ukujiya kokumboza kuyahambisana kuyo yonke i-substrate.
Isinyathelo sesi-3: Ukushisa Ngaphambi kokuba i-powder isetshenziswe, i-substrate ishisa ngaphambili. Lesi sinyathelo siyadingeka ukuze uncibilikise i-powder futhi udale ukugqoka okufanayo ku-substrate. Izinga lokushisa lenqubo yokushisa ngaphambili lizokwenza depekanye nempahla ethile yempushana esetshenziswayo, kodwa ngokuvamile isukela ku-180 kuya ku-220 degrees Celsius.
Isinyathelo sesi-4: Ukuncibilika Uma i-substrate isishisiwe ngaphambili, icwiliswa kumbhede owuketshezi wempushana. Impushana imisiwe emoyeni, idala umbhede omanzi ozungeza i-substrate. Njengoba i-substrate yehliselwa embhedeni omanzi, izinhlayiya ze-powder zinamathela ebusweni bayo, zenze i-coating efanayo.
Ukushisa okuvela enkambisweni yokushisa kubangela ukuthi izinhlayiya ze-powder zincibilike futhi zigeleze ndawonye, zakha ifilimu eqhubekayo ku-substrate. Inqubo yokuncibilika ngokuvamile ithatha phakathi kwamasekhondi angu-20 kuya kwangu-30, depei-nding on the ukushuba kwe-coating kanye nezinga lokushisa lombhede omanzi.
Isinyathelo sesi-5: Ukwelapha Isinyathelo sokugcina enqubweni yokuhlanganisa impushana yombhede omanzi ukulapha. Uma isimbozo sesisetshenzisiwe, sishiswa ekushiseni okuphezulu ukuze kwelaphe impushana futhi kwakhiwe isiphetho esiqinile, esihlala isikhathi eside. Izinga lokushisa lokupholisa kanye nesikhathi kuyokwenza depekanye nempahla ethile yempushana esetshenziswayo, kodwa ngokuvamile isukela ku-150 kuya ku-200 degrees Celsius imizuzu eyi-10 kuye kweyi-15.
Phakathi nenqubo yokwelapha, izinhlayiya zempushana ziyaphambana futhi zisabela ngokwamakhemikhali ukuze zenze uqweqwe oluqinile, oluqinile olunamathela ku-substrate. Inqubo yokwelapha ibalulekile ukuze kuqinisekiswe ukuqina kwento enamathelayo, ukumelana nokuhuzuka, nokumelana namakhemikhali.
Sengiphetha, i-fluidized bed powder coating iyindlela eguquguqukayo futhi ephumelelayo yokumboza ama-substrates ngezinto zempushana. Inqubo ihilela ukulungiswa kwe-substrate, isicelo se-powder, ukushisa kwangaphambili, ukuncibilika, nokuphulukisa, okubaluleke kakhulu ekuphumeleleni kokugqoka. Ngokuqonda ukuthi i-fluidized bed powder coating isebenza kanjani, ungenza izinqumo ezinolwazi mayelana nokuthi le nqubo ilungele isicelo sakho esithile.
