Inayiloni Powder Electrostatic Spray Coating Inqubo

Indlela yesifutho ye-electrostatic isebenzisa umthelela wokungenisa wenkundla kagesi ene-voltage ephezulu noma umphumela wokushaja ukushayisana ukuze ibangele amashaji aphambene kugesi. inayiloni powder kanye nento eboshiwe, ngokulandelana. I-powder ene-charged enamathelayo ikhangwa into eboshwe ngokuphambene, futhi ngemva kokuncibilika nokulingana, inayiloni enamathela iyatholakala. Uma imfuneko yokuqina kokumboza ingeqi ama-microns angama-200 futhi i-substrate iyinsimbi engaphonswanga noma i-porous, akukho ukushisa okudingekayo ekufutheni okubandayo. Ukuze kuhlanganiswe impushana enezidingo zokujiya ezingaphezu kwama-microns angu-200 noma ama-substrates anensimbi ecijile noma izinto ezimbotshana, i-substrate idinga ukushisisa kuze kufike ku-250°C ngaphambi kokufafaza, okubizwa ngokuthi ukufutha okushisayo.

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 inohlu olubanzi lwezinketho zokukhetha osayizi be-workpiece, ikakhulukazi ama-workpiece anobukhulu obuhlukahlukene, okuqinisekisa ukushuba okufanayo. Lapho i-workpiece ingavaliwe ngokuphelele noma inomumo oyinkimbinkimbi ongakwazi ukucwiliswa ku-a umbhede omanzi, inqubo yokufafaza nge-electrostatic inezinzuzo. Itheyiphu yokunamathela enokushisa okuphezulu, engagqoki ingasetshenziselwa ukuvikela okwesikhashana izingxenye ezingamboziwe. Ngokuvamile, ukufafaza nge-electrostatic kungafinyelela ukunamathela okuncane, okuphakathi kwama-microns angu-150 nama-microns angu-250. Ukwengeza, ukumbozwa kwenayiloni okutholwe ngokufafaza okubandayo kwe-electrostatic kunezinga lokushisa eliphansi elincibilikayo, ngokuvamile elizungeze u-210-230°C imizuzu engu-5-10, ukuqina okuhle, kanye nokuwohloka okuphansi kokushisa. Ukunamathela ensimbi kungcono kunezinye izinqubo.
