Ukwethulwa kwemishini yokufafaza nge-electrostatic
Imishini yokufafaza nge-electrostatic
Imishini yokuthungula i-electrostatic i-powder coating eyaziwa kakhulu ngokuthi "i-electrostatic spray". Isifutho singaba semanuwali, sizenzekele noma sibe semanyuwali + sizenzekele. I-100% yezinto ezifuthwayo ziyimpushana eqinile, izimpushana zamahhala zingasebenzisa kabusha izinga lokugaywa kabusha kopende kuze kufike ku-98%. Ukumiswa kohlelo lwezokuthutha, izinga eliphezulu lokuzenzakalela. I-microporous camera kancane, ukumelana nokugqwala okuhle, futhi ingaba ifilimu ewugqinsi.
I-electrostatic powder coating esekelwe ekubeni ne-Tsui ye-atomizing (i-atomizing kapende), kanye nesiteji sokukhipha (inkokhelo yamanje iyenzeka) umshini wokugcoba ukuze izinhlayiya zopende, zisetshenziswe kumapheya okushaja bese kwakhiwa insimu kagesi phakathi kwe-electrode kanye into ezogqitshwa, kusetshenziswa i-electrostatic adsorption coating.
Inqubo yokumboza nge-electrostatic powder yavela ngeminyaka yawo-1960, isetshenziswa kakhulu ekunambeni kwendawo yensimbi. Ngasekupheleni kwawo-1990 kuya ekhulwini lama-20, ngokuthuthukiswa kwempuphu enamathela kanye nemishini yokufafaza, inqubo yokumboza i-electrostatic powder isetshenziswa ku-non-metallic indawo engenzeka.
Ngemithetho yezemvelo yezidingo eziqinile ngokuya kokuqukethwe komkhathi wezinto eziphilayo eziguquguqukayo (voc), imboni yokumboza ibizama ukuthuthukisa ubuchwepheshe bokunamathela obulinganiselayo emvelweni, imishini yothuli ye-Ningbo etholwe ngemuva kocwaningo lwesikhathi eside kanye nempushana yokuhlola i-electrostatic. enamathela ukufeza ehlanzekile enamathela ubuchwepheshe.
I-Powder coating ayisebenzisi i-solvent ephilayo, amanzi nezinye izincibilikisi eziguquguqukayo, i-solvent-based based coatings, enciphisa kakhulu i-solvent ngenxa yenkathazo yokungcola okubangelwa ubuthi bezisebenzi ezisebenzayo, kuhlanganise ne-solvent equkethe; ngeke kubangele i-solvent ephilayo futhi kubangele umlilo.Kusuka ku-powder coating etholakalayo kuze kube manje, akuzange kubangele izingozi ezinkulu ngenxa yokugqoka i-powder.
I powder enamathela kuyinto enamathela, okumsulwa ingxenye eqinile kungaba okuzenzakalelayo ngokuphelele sishaye esikhulu noma super spray powder kwaqoqwa kalula uhlelo alulame, ukufeza inhloso kabusha. Ngakho-ke, izinga lokusebenzisa i-powder coating cishe lifika ku-100%, okwenza imboni yokumboza inciphise izindleko zokulahla imfucuza, futhi ngesikhathi esifanayo inganciphisa izinga lokungcoliswa kwemvelo. Izinzuzo zezomnotho ezibalulekile.
Ingxenye yokuhlanganisa ifilimu, uhlobo lwe-solvent mayelana no-60% kuya ku-65%, kuyilapho i-powder enamathela ingafinyelelwa ukusebenza kahle kwe-100%, futhi ingaxhunywanga entweni okufanele ifuthwe impushana ingaphinda isetshenziswe. Ngaphansi kwezimo ezijwayelekile, ukusetshenziswa kobuchwepheshe be-powder coating yokudweba kungaba ngangokunokwenzeka ukuze kuzuzwe umnotho nokusebenza kahle. In the operation powder enamathela, uma kukhona sishaye izingxenye ezimbi kungaba ngaphandle ngaphambi baking, usebenzisa isibhamu air spray bahlanzwe, bese kabusha upende. Ngakho-ke, ukuze ugweme ukugeleza kwamanzi upende amaconsi upende mkhuba, kakhulu kunciphisa ithuba rework recoating.
Ukusebenzisa imisebenzi yokufafaza nge-electrostatic ngenxa yempushana enamathelayo, imishini yokudweba icishe ifike ku-othomathikhi ngokugcwele, kusindisa umthombo womuntu. Ngisho nokwenziwa, ukudweba isikhathi eside sokuqeqeshwa akudingekile ukuze uphumelele amakhono okusebenza. I-powder coating iyinhlanganisela ye-solids engu-100%, ngaphandle kokwengeza noma iyiphi i-solvent, inani le-coating liyancishiswa, lilondoloza ukupakisha, linciphisa indawo yokugcina.
