I-powder impregnation ikhiqizwa ngenqubo yombhede omanzi. Kujeneretha yegesi yakwaWinkler, umbhede owuketshezi waqale wasetshenziselwa ukubola kokuxhumana kwe-petroleum, kwase kwakhiwa inqubo yokuxhumana yezigaba ezimbili zegesi eqinile, yase isetshenziswa kancane kancane embotsheni yensimbi. Ngakho-ke, ngezinye izikhathi kusabizwa ngokuthi "indlela yokugqoka i-fluidized bed coating". Inqubo yangempela iwukwengeza i-powder coating ngaphansi kwesiqukathi esingenamanzi esinezimbotshana (umkhombe wokugeleza), faka umoya ocindezelwe osuka ku-blower, bese uwucubungula ukuze uguqule ukumbozwa kwempushana kusesimweni "se-fluidization".
Umbhede omanzi yisigaba sesibili sokugeleza kwezinto eziqinile (esokuqala yisiteji sombhede ongashintshi, kanti okwesibili yisiteji sokulethwa kwegesi). Ngesisekelo sombhede ohleliwe, qhubeka nokwandisa izinga lokugeleza (W), umbhede uqala ukwandisa futhi ukhulule, futhi ukuphakama kombhede kuqala ukwanda. , I-powder particle ngayinye. I-E iyantanta, ngaleyo ndlela ishiya indawo yokuqala ukuze ibe nezinga elithile lokunyakaza. Bese ufaka isiteji sombhede omanzi.
Isigaba BC sibonisa ukuthi ungqimba lwe-powder embhedeni omanzi luyanda, futhi ukuphakama kwalo (I) kuyanda ngokunyuka kwesivinini segesi, kodwa ukucindezela embhedeni akukhuphuki (ΔP). Umbhede omanzi ngeke uguqule izinga lokugeleza phakathi kwebanga elithile, futhi ngeke uthinte amandla athile adingwa uketshezi. Lesi yisici sombhede owenziwe ngamanzi, osetshenziselwa inqubo yokumboza. Ukufana kwesimo se-fluidization embhedeni omanzi kuyisihluthulelo sokufana kwe-coating. Umbhede onoketshezi osetshenziselwa ukumboza ngempushana ungowokuthi "i-vertical fluidization". Inombolo ye-fluidization itholakala ngokuhlolwa. Ngokuvamile, kungenziwa camera. Izinga lokumiswa kwe-powder embhedeni omanzi lingafinyelela ku-30% -50%.
