Umgca wokugquma umgubo ubalulekile kwi-MDF yokugqoka umgubo
Umgca wokugubungela umgubo ubonakalise ukuba yeyona nto ibalulekileyo ekufumaneni umgangatho ophezulu we-MDF Ipeyinti. Ngelishwa kwiinkampani ezincinci zokugquma umgubo wentsimbi, akunakwenzeka ukufumana umgangatho ophezulu we-MDF yokwaleka kwimigca yentsimbi emidala yokugquma.
Inxalenye ebaluleke kakhulu yomgca wokugquma umgubo yipeyinti ye-oven ye-oven enyibilikayo. Kwimeko yokunyanga i-thermal powder ukunyanga imichiza. Into emele igcinwe engqondweni yi-conductivity ephantsi ye-thermal ye-MDF. Ngoko ke, ii-ovens kufuneka zenziwe ukuze ubushushu bazo buhanjiswe ngokulinganayo; kungenjalo, ubushushu abuyi kwabelwa ngapha komphezulu substrate njenge aluminiyam. Nangona kunjalo, xa ukufudumala kwi-MDF, kufuneka kuqinisekiswe ukuhanjiswa kweqondo lokushisa okufanayo
Sisanda kusebenzisa oku ngenxa ye-thermal conductivity ye-MDF ephantsi. Njengoko kukhankanyiwe ngaphambili, umgubo uyanyibilika kwaye uqina kwiqondo lokushisa elifanelekileyo. Eli qondo lobushushu lixhaphake ngaphezu kokuba i-MDF inokusingatha. Nangona kunjalo, xa i-powder itshiswa yimitha ye-infrared, i-powder kunye nebhodi yebhodi ifikelela ngokukhawuleza kwiqondo lokushisa lokunyibilika kunye nokuqina. Ngenxa yokucotha kwe-thermal conductivity yebhodi, iqondo lokushisa eliphakathi kwebhodi lisephantsi, liphantsi kakhulu kuneqondo lokushisa apho yonke i-powder inyibilika kwaye iqiniswe. Ngoko ke, uxinzelelo lwe-thermal kwibhodi ye-MDF luyancitshiswa ngaphandle kokubangela umonakalo
Siyabona ukuba ii-oveni ezimbini eziveliswe ngasentla kukunyanga kwe-thermal kunye ne-UV yokunyanga inyibilika, ezingafanelanga ukugquma komgubo we-MDF. Ukunyangwa kwe-thermal ye-powder eqhelekileyo kunye nokufudumala kwe-MDF kuthatha ixesha elide ukufikelela kwi-150-160 degrees ngenxa ye-thermal conductivity ephantsi ye-MDF. Ngenxa yoko, i powder ayizange iphiliswe ngokupheleleyo kwaye i-MDF yonakaliswe. Olunye unyango lwe-UV, ukuza kuthi ga ngoku ukuze kuphunyezwe ukuhanjiswa okufanayo kobunzulu be-UV kunye nethamo, kwangaxeshanye inqanaba lokunyangwa kweendlela ezahlukeneyo. imibala, ukutyeba okwahlukeneyo komgubo. Ke ngoko, ukunyangwa kwe-UV akukasebenzi ngempumelelo umzekelo we-MDF yokwambathisa umgubo. Nangona kunjalo, ukunyangwa kwe-UV kusetyenziswa kwi-MDF yomgubo we-powder we-powder ebonakalayo esekelwe kwi-optical layers (engachazwanga kulo mzekelo).
Isicelo esiyimpumelelo sokunyibilika kunye nokunyangwa kweengubo ze-MDF ze powder yi-oven infrared. Umngeni kukubonelela ngokuvezwa kwe-IR efanayo kumphezulu we-MDF, kubandakanywa nemiphetho. Ngethamsanqa, ii-oveni ze-infrared zanamhlanje zinezinga eliphezulu lemitha efanayo. Umzobo we-6 yimephu yokusasazwa kobushushu bomphezulu obulinganiswa ngamaqondo aphezulu aphezulu, aphakathi kunye naphantsi kwe-MDF ye-infrared oven. Ukwabiwa kwamaqondo obushushu kumphezulu we-MDF kuyahluka kancinci, kwaye iqondo lobushushu lingaphantsi kwe-15°F
I-oveni eyilwe kakuhle ye-IR ebonisa utshintsho lobushushu obungaphantsi kwe-15°F ukusuka phezulu ukuya ezantsi kwe-MDF substrate.
Ukuze ufumane i-powder efanelekileyo yokugqoka, ukuhanjiswa kweqondo lokushisa kwi-oven kufuneka kulinganiswe ngaphambi kokuba kuqaliswe i-powder powder. Ukulinganisa kunye nokubeka iliso kungekuphela kwendawo engaphezulu, kodwa nakwi-MDF ebusweni, kubandakanywa nemiphetho yayo. Amaqondo obushushu e-oveni kufuneka ahlengahlengiswe ukunqanda umahluko wobushushu phakathi kweendawo ezingaphaya kwemida, ezinje ngaphantsi kwe-15°F. Umzobo 7 lunikezelo olubini lobushushu kwiiphaneli u-a kunye no-b. Umzobo 7a yi-oven ene-infrared ene-conditioning kakuhle; inzwa igxininiswe kwiindawo ezahlukeneyo kwi-MDF surface, kubandakanywa nemiphetho. Siyabona ukuba ukuhanjiswa kweqondo lokushisa kwindawo ye-MDF kufana kakhulu.
Ngokucacileyo, ii-oveni ze-MDF ezinomgangatho wobushushu obuphezulu zitshintsha ngaphezulu kwe-75 ° F aziyi kufezekisa ukusebenza okufanayo komgubo. Kwezinye iimeko, kwanokusasazwa kobushushu obufanayo akunakufezekiswa ngenxa yokungaphumeleli kobugcisa kwi-oven. Kwezinye iimeko, ii-ovens ezenziwe kakuhle zibekwe kwiqondo lokushisa elifanelekileyo. Ezi meko zikhokelela ekubeni i-powder powder ayifanele isetyenziswe kwimveliso kwaye kwiimeko ezininzi zikhokelela ekungaphumeleli kwe-MDF powder powders.
Kwisayizi ye-substrate enikeziweyo (kubandakanywa nemiphetho), inyibilika - ukushisa okuphezulu kwe-oven yokunyanga, ingxoxo efanelekileyo, kunye nemithetho engqongqo ngaphambi kokuba wenze naziphi na izigqibo kunye nomenzi. Emva kokuba i-oven ifakiwe, ukuseta umgca wemveliso kufuneka uphuculwe ngomlinganiselo weprofayili yeqondo lokushisa kunye nokuhlolwa kweprofayili yokushisa okuqhubekayo ngexesha lemveliso. Oku kuya kuqinisekisa ukuba umgangatho wepowder coating ungaphakathi kwenkcazo.
