I-powder coating line ibalulekile i-MDF powder coating
I-Powder coating line ifakazele ukuthi iyisici esibaluleke kakhulu ekutholeni ikhwalithi ephezulu ye-MDF i-powder coatings. Ngeshwa ezinkampanini ezincane zokumboza i-powder surface yensimbi, akwenzeki ukuthola ikhwalithi ephezulu ye-MDF yempushana emigqeni emidala ye-metal powder coating.
Ingxenye ebaluleke kakhulu yomugqa wokugcoba i-powder ukuncibilika kwepende ye-oven technology. Uma kwenzeka ukuphulukiswa okushisayo kwempushana ukuphulukiswa kwamakhemikhali. Into okufanele uyikhumbule ukuthi i-thermal conductivity ye-MDF iphansi. Ngakho-ke, amahhavini kudingeka aklanywe ukuze izinga lokushisa lawo lisatshalaliswe ngokulinganayo; ngaphandle kwalokho, ukushisa ngeke kusatshalaliswe endaweni engaphansi njenge-aluminium. Kodwa-ke, lapho kushisa ku-MDF, kufanele kuqinisekiswe ukusatshalaliswa kokushisa okulinganayo kwendawo
Sisanda kusebenzisa leli thuba ngenxa ye-thermal conductivity ephansi ye-MDF. Njengoba kushiwo ngaphambili, impushana iyancibilika futhi iqina ekushiseni okufanele. Lokhu kushisa kuvame ukwedlula i-MDF engakwazi ukuyiphatha. Kodwa-ke, lapho impushana ishiswa imisebe ye-infrared, impushana nendawo yebhodi ifinyelela ngokushesha izinga lokushisa lokuncibilika nokuqiniswa. Ngenxa ye-conductivity yokushisa ephansi yebhodi, izinga lokushisa eliphakathi kwebhodi namanje liphansi, liphansi kakhulu kunokushisa lapho yonke i-powder incibilika futhi iqiniswe. Ngakho-ke, ukucindezeleka okushisayo ebhodini le-MDF kuyancishiswa ngaphandle kokudala umonakalo
Siyabona ukuthi ohhavini ababili abethulwe ngenhla bawukwelapha okushisayo kanye nokwelapha okuncibilikisa kwe-UV, okungafanele ukugcotshwa kwempuphu ye-MDF. Ukwelashwa okujwayelekile kwe-powder yonke kanye nokushisa kwe-MDF kuthatha isikhathi eside ukufinyelela ama-degree angu-150-160 ngenxa ye-thermal conductivity ephansi ye-MDF. Ngenxa yalokho, i-powder ayizange ilashwe ngokugcwele futhi i-MDF yonakalisiwe. Okunye ukuphulukiswa kwe-UV, kuze kube manje ukuze kuzuzwe ukusatshalaliswa okufanayo kokuqina kwe-UV kanye nomthamo, ngasikhathi sinye izinga lokuphulukiswa kwezifo ezahlukahlukene. imibala, ukujiya kwe-powder ehlukahlukene. Ngakho-ke, ukuphulukiswa kwe-UV akukasebenzisi ngempumelelo isibonelo se-MDF powder coating. Kodwa-ke, ukuphulukiswa kwe-UV kusetshenziselwa i-MDF powder coating of the transparent powder based layers optical (akuningiliziwe kulesi sibonelo).
Isicelo esiphumelelayo sokuncibilika kanye nokuphulukiswa kwe-MDF powder coatings i-oven infrared. Inselele ukuhlinzeka ngokuchayeka kwe-IR efanayo endaweni ye-MDF, kufaka phakathi imiphetho. Ngenhlanhla, ohhavini besimanje be-infrared banezinga eliphezulu lemisebe efanayo. Umfanekiso 6 imephu yokusabalalisa izinga lokushisa elingaphezulu elikalwa ngezinzwa zokushisa ezingaphezulu, ezimaphakathi neziphansi ze-infrared oven MDF. Ukusabalalisa kwezinga lokushisa endaweni ye-MDF kuyehluka kancane kakhulu, futhi izinga lokushisa lingaphansi kuka-15°F
Ihhavini epholile ye-IR eklanywe kahle ebonisa izinguquko zokushisa ngaphansi kuka-15°F ukusuka phezulu kuye phansi kwe-MDF substrate.
Ukuze uthole i-powder coating enhle, ukusatshalaliswa kwezinga lokushisa kuhhavini kufanele kulinganiswe ngaphambi kokuqala ukumbozwa kwe-powder. Kala futhi uqaphe hhayi kuphela endaweni engaphezulu, kodwa futhi nxazonke ze-MDF, kuhlanganise nemiphetho yayo. Amazinga okushisa kahhavini kufanele alungiswe ukuze kugwenywe umehluko wokushisa phakathi kwezindawo ezeqa imikhawulo, njengendawo engaphansi kuka-15°F. Umfanekiso 7 ukusabalalisa okubili kwezinga lokushisa kumaphaneli u-a no-b. Umfanekiso 7a uwuhhavini one-infrared onesimo esihle; inzwa igxilile ezindaweni ezihlukahlukene endaweni ye-MDF, kuhlanganise nemiphetho. Siyabona ukuthi ukusatshalaliswa kwezinga lokushisa endaweni ye-MDF kufana kakhulu.
Ngokusobala, amahhavini e-MDF anesethi yamazinga okushisa aphezulu ashintsha ngaphezu kuka-75 ° F ngeke azuze ukusebenza okufanayo kwe-powder coating. Kwezinye izimo, ngisho nokusatshalaliswa kokushisa okufanayo akukwazi ukufezwa ngenxa yokushiyeka kwezobuchwepheshe kuhhavini. Kwezinye izimo, amahhavini aklanywe kahle abekwe ezingeni lokushisa elifanele. Lezi zimo ziholela eqinisweni lokuthi izigqoko ze-powder akufanele zisetshenziswe ekukhiqizeni futhi ezimweni eziningi ziholela ekuhlulekeni kwe-MDF powder coatings.
Kusayizi onikeziwe we-substrate (kuhlanganise nemiphetho), ncibilika - izinga lokushisa eliphakeme kakhulu likahhavini wokwelapha, ingxoxo enhle, nemithetho eqinile ngaphambi kokwenza noma yiziphi izinqumo nomkhiqizi. Uma uhhavini usufakiwe, ukusethwa kolayini wokukhiqiza kufanele kuthuthukiswe ngokulinganisa iphrofayili yezinga lokushisa kanye nokuqapha okuqhubekayo kwephrofayili yokushisa ngesikhathi sokukhiqiza. Lokhu kuzoqinisekisa ukuthi izinga le-powder coating lingaphakathi kokucaciswa.
