Inayiloni Powder Electrostatic Spray Coating Inqubo

Indlela yokufutha nge-electrostatic isebenzisa umphumela wokungeniswa kwensimu kagesi ene-voltage ephezulu noma umphumela wokushaja kwe-friction ukuze kubangele amacala aphambene ku- nylon powder kanye nento eboshwe, ngokulandelana. I-charged powder coating ikhangwa yinto eboshwe eboshwe eboshwe ebhekene, futhi ngemva kokuncibilika nokuleveli, kutholakala i- nylon coating . Uma isidingo sobukhulu be-coating singadluli ama-micron angu-200 futhi i-substrate ingeyona i-cast iron noma ine-porous, akukho ukushisa okudingekayo ukuze kufuthwe ngokubandayo. Ukuze kufakwe i-powder coating enezidingo zobukhulu ezingaphezu kwama-micron angu-200 noma i-substrate ene-cast iron noma izinto ezine-porous, i-substrate idinga ukushiswa cishe kuma-250°C ngaphambi kokufutha, okubizwa ngokuthi i-hot spray.

Ukufafaza okubandayo kudinga izinhlayiya zempushana enayiloni ukuze zibe nobubanzi obungama-microns angaba ngu-20-50. Kwesinye isikhathi, inkungu yamanzi ingafuthwa kumpushana ukuze kwandiswe amandla ayo okuthwala amashaji futhi kuncishiswe iziphambeko ezibangelwa ukulahleka kwempushana ngaphambi kokubhaka. Ukufafaza okushisayo kudinga izinhlayiya zempushana enayiloni ukuze zibe nobubanzi obufika kuma-microns ayi-100. Izinhlayiya ezimahhadla zingaphumela ekujiyileni okukhulu, kodwa izinhlayiya ezimahhadla ngokweqile zingavimbela ukunamathela kwempushana. Ngesikhathi sokufafaza okushisayo, izinga lokushisa le-substrate liyancipha ngokuqhubekayo, okwenza kube nzima ukulawula ubukhulu, kodwa ukumboza ngeke kukhiqize amaphutha okulahlekelwa kwe-powder.

Inqubo yokufafaza nge-electrostatic inezinketho eziningi zokukhetha osayizi bezinto zokusebenza, ikakhulukazi zezinto zokusebenza ezinobukhulu obuhlukene, okuqinisekisa ubukhulu obufanayo. Uma into yokusebenza ingamboziwe ngokuphelele noma inesimo esiyinkimbinkimbi esingenakucwiliswa embhedeni omanzi , inqubo yokufafaza nge-electrostatic inezinzuzo. Itheyiphu yokunamathela enokushisa okuphezulu, engagugi ingasetshenziswa ukuvikela okwesikhashana izingxenye ezingamboziwe. Ngokuvamile, ukufafaza nge-electrostatic kungafeza ungqimba oluncane, oluphakathi kwama-micron angu-150 nama-micron angu-250. Ngaphezu kwalokho, ungqimba lwe-nylon olutholwe ngokufafaza nge-electrostatic cold lunokushisa okuphansi kokuncibilika, ngokuvamile cishe ku-210-230°C imizuzu emi-5-10, ukuqina okuhle, kanye nokuwohloka okuphansi kokushisa. Ukunamathela ensimbini kungcono kunezinye izinqubo.
