Isebenza njani iBed Powder Coating eFluidized?
Ibhedi ene-fluidized umgubo wokwaleka yinkqubo yokwaleka i-substrate ngezinto zomgubo ocolekileyo. Inkqubo ibandakanya ukuxhoma izinto zomgubo kumlambo womoya, ukudala ibhedi edibeneyo yomgubo ovumela ukuba kunye nokugquma kwe-substrate. Kweli nqaku, siza kuhlolisisa indlela ibhedi engumgubo yokwaleka sebenza.
Inkqubo yokwaleka kwebhedi engumgubo inokwahlulwa ibe ziintsika ezintlanueps: ukulungiswa kwe-substrate, ukusetyenziswa komgubo, ukushisa kwangaphambili, ukunyibilika kunye nokunyanga.
Inyathelo 1: Ukulungiswa kweSubstrate Inyathelo lokuqala kwinkqubo yokugquma ibhedi engumgubo kukulungiswa kwesubstrate. Oku kubandakanya ukucoca i-substrate ukususa naluphi na ukungcola, igrisi okanye ezinye izinto ezingcolileyo ezinokuthintela umgubo ekubambeni ngokufanelekileyo. Eli nyathelo libaluleke kakhulu kwimpumelelo yenkqubo, njengoko nayiphi na into engcolileyo kwi-substrate inokuphazamisa ukunamathela kunye nokuqina kwengubo.
Inyathelo lesi-2: Ukusetyenziswa kwePowder Emva kokuba i-substrate icocekile kwaye yomile, ilungele inyathelo lesicelo somgubo. Isixhobo somgubo sigcinwa kwi-hopper okanye kwisingxobo, apho sibalwa kusetyenziswa isixhobo sokukhupha. Isixhobo sokuhambisa sinokuhlengahlengiswa ukulawula ubungakanani bepowder esetyenzisiweyo, ukuqinisekisa ukuba ubukhulu bengubo buhambelanayo kwi-substrate.
Inyathelo lesi-3: Ukufudumala Emva kokuba umgubo usetyenziswe, i-substrate ifakwe ngaphambili. Eli nyathelo liyimfuneko ukunyibilikisa umgubo kwaye wenze i-coating efanayo kwi-substrate. Ubushushu benkqubo yokufudumeza kwangaphambili depekunye nemathiriyeli ethile yomgubo esetyenziswayo, kodwa ngokwesiqhelo iqala kwi-180 ukuya kuma-220 ngokukaCelsius.
Inyathelo lesi-4: Ukunyibilika Xa i-substrate sele ifudunyeziwe ngaphambili, intywiliselwa kumandlalo womgubo omanzi. Umgubo unqunyanyiswa kumlambo womoya, udala ibhedi emanzi ejikeleze i-substrate. Njengoko i-substrate iyancipha kwi-bed fluidized bed, i-powder particles ibambelela kwindawo yayo, idala isambatho esifanayo.
Ukushisa okuvela kwinkqubo yokufudumala kubangela ukuba i-powder particles inyibilike kwaye ihambe kunye, yenze ifilimu eqhubekayo kwi-substrate. Inkqubo yokunyibilika idla ngokuthatha phakathi kwemizuzwana engama-20 ukuya kuma-30, depeI-nding kwi-thickness of the coating kunye nobushushu bebhedi edibeneyo.
Inyathelo lesi-5: Ukunyanga Inyathelo lokugqibela kwinkqubo yokugquma ibhedi engumgubo kukunyanga. Emva kokuba i-coating isetyenzisiwe, ifudunyezwa kwiqondo lokushisa eliphezulu ukunyanga i powder kunye nokudala ukugqiba, ixesha elide. Ubushushu obunyangayo kunye nexesha liya depekunye nemathiriyeli ethile yomgubo esetyenziswayo, kodwa iqheleke ukusuka kwi-150 ukuya kuma-200 degrees celsius kangangemizuzu eli-10 ukuya kweli-15.
Ngethuba lenkqubo yokunyanga, i-powder particles crosslink kunye neekhemikhali zisabela ukuze zenze i-coating eqinile, ehlala ibambelele kwi-substrate. Inkqubo yokunyanga ibalulekile ekuqinisekiseni ukuqina kwengubo, ukuxhathisa kwi-abrasion, kunye nokuxhathisa imichiza.
Ukuqukumbela, i-fluidized bed powder coating yindlela eguquguqukayo kunye nesebenzayo yokugquma i-substrates kunye nezinto eziphathekayo zomgubo. Inkqubo ibandakanya ukulungiswa kwe-substrate, isicelo somgubo, ukushisa kwangaphambili, ukunyibilika, kunye nokunyanga, nganye eyona nto ibalulekileyo kwimpumelelo yokugqoka. Ngokuqonda indlela i-fluidized bed powder coating isebenza ngayo, unokwenza izigqibo ezinolwazi malunga nokuba le nkqubo ilungile kwisicelo sakho esithile.
