I-Functional Powder Coating: I-Insulated futhi I-Conductive Powder coating

The i-powder coating iwuhlobo olusha lwe-solvent-free 100% enembozo yempushana eqinile. Inamandla angancibiliki, angangcolisi, agaywa kabusha, anobungani nendawo ezungezile, eyonga amandla nezisetshenziswa, futhi enciphisa umfutho wabasebenzi namandla emishini yefilimu. Ifomu le-coating kanye nokwakheka kwezinto eziqinile zokugqoka ezifika ku-100%, ngoba azisebenzisi izincibilikisi, ngaleyo ndlela zinciphisa ukungcoliswa kwemvelo, zilondoloze izinsiza kanye nezici ezivuselelekayo.

The ukusebenza kwe-powder coating kuwumsebenzi okhethekile, izinto zokumboza ezingaphezulu zokuhlinzeka ngezinjongo ezikhethekile. Ayigcini nje ngokudlala indima evamile yokuvikela nokuhlobisa, futhi iphinde inikeze izinto ezibonakalayo ezihlukahlukene zemisebenzi ethile, okuhlanganisa ukugqumisa, ukuqhutshwa, ukulwa nokungcola, ukushisa, ukubuyiswa komlilo, ukuvikelwa kwemisebe kanye neminye imisebenzi.
Ukuthuthukiswa nokukhiqizwa kwezingubo zempushana ezisebenzayo kusanda kuqala, kusasele emuva kakhulu ngezinga elithuthukile lakwamanye amazwe. I-gene ye-powder coatings ejwayelekile esetshenziswayoralbanezinhlobo ezilandelayo:

I-Insulated Powder Coatings

I-insulation powder coating I-coating ekhethekile isetshenziselwa izinjini, izingxenye zikagesi neze-elekthronikhi, ngaphezu kokuvikela isakhi sofuzo.ral i-powder coatings, izakhiwo zokuhlobisa, kodwa futhi inezindawo ezinhle zokuhlukanisa ugesi.

Ama-epoxy resins ayizinto ezinhle kakhulu zokusetshenziswa zokwenziwa kwe-insulating powder coating.Ngokushintsha uhlobo lwe-ejenti yokwelapha, noma wengeze isilungisi esikhethekile futhi esinokweqa okuhle nokumelana nokushisa kwama-fillers ukulungisa izinga lokuphulukisa, elitholakala ngokuthambile kakhulu, okuguquguqukayo, okuqinile kakhulu. , gqoka izinhlobonhlobo ze-coating ukuze uvumelane nezimo ezihlukene zokuhlukanisa. Eminyakeni yamuva, ngaphandle kwe-epoxy powder enamathela, i-polyurethane powder coating, i-poly coating ye-polyimide, i-acrylic powder coatings, njll. nazo zithuthukiswa futhi zisetshenziswa njalo.

I-conductive powder coatings

I-powder conductive coating isetshenziswa ku-substrate engeyona e-conductive, ukuze ibe namandla athile okuqhuba kanye nokuqedwa komthamo we-electrostatic wezingubo zokusebenza. Izembatho ezinjalo ngokuyinhloko ziyizinhlobo ezimbili: uhlobo lokuxuba kanye nohlobo lwangaphakathi

Izingubo ze-powder ezihlanganisiwe ziyizinto zokwakha ifilimu ye-polymer enamathela, ukwakheka lapho ukufakwa kwe-conductive fillers. I-conductive filler, impushana yensimbi, njengesiliva, nickel, zinc, aluminium, njll.; okungeyonametallic powder, njenge-graphite, i-carbon black; ama-oxide ensimbi njenge-zinc oxide, i-antimony oxide. I-binder Khetha ama-vinyl resins, ama-polyester resins, i-polyamide ne-epoxy resin.

I-polymer conductive intrinsic i-polymer ngokwayo iyaqhuba, isigaba samanje se-polymer sisesigabeni sethiyori nokucwaninga, akukho sicelo esisebenzayo.

I-Anticorrosive powder coating

Njengamanje usebenzisa izigqoko ezinjalo ze-epoxy phenolic anti-corrosion powder ezimboza nge-epoxy resin kanye ne-phenolic resin-based-forming film-forming substances, kokubili ukwakheka kokuxhumanisa kwe-coating. Lolu hlobo lukapende olusetshenziswa ku-epoxy luwufuzoralisetshenziswa kahle ohlotsheni lwe-polymer yesisindo samangqamuzana angu-1400,2900 no-3570. I-epoxy resin ngokwayo, ukunamathela, ukuguquguquka nokuphikiswa kwe-alkali nokuhle, ne-phenolic resin ene-asidi enhle kakhulu, i-solvent, ukushisa, umswakama ukusebenza okubandayo kuhlanganiswe ukuze kube yi-anti-corrosion. materials izinhlobo ekahle. Ukusebenza okubuthakathaka phakathi kwe-epoxy ne-phenolic resin coating ifilimu yokushisa izinga lokushisa elidingekayo ezimweni eziphakeme, ngokwengeza inani elifanele le-imidazole catalyst ukunciphisa izinga lokushisa lokuphulukisa.

I-powder engazweli ekushiseni

I-powder ekwazi ukumelana nokushisa isikhathi eside ingamelana namazinga okushisa angaphezu kuka-200 ℃, ifilimu enhle, futhi yenze into evikelayo endaweni yokushisa ephezulu isebenze kahle.

Kusukela kumshini wokuzinza kwe-polymer ezishisayo, ukumelana nokushisa kwe-polymer kuncike ekwakhekeni kwayo kwamangqamuzana. Ngakho-ke, ukwandisa amandla okusebenzelana kwe-intermolecular ngokusungulwa kwamaqembu amakhulu noma ngaphezulu kwe-polar side ku-chain main, ngaleyo ndlela kuthuthukiswe ukuzinza kokushisa kwe-polymer. Enye indlela ukuthuthukisa ukumelana nokushisa kwezimbobo zempushana ngokungeza ama-pigments angavimbeli ukushisa nama-filler ku-polymer. Okuvame ukusetshenziselwa izingulube, izigcwalisi ziyi-aluminium powder, i-mica powder, i-stainless steel powder, i-cadmium powder, i-silica. Njengamanje, i-powder engazweli ekushiseni iseyi-silicone powder coatings esekelwe. Lokhu kwemboza isiqondiso esiyinhloko samandla okuthuthukiswa kocwaningo lwesikhathi esizayo emazingeni okushisa aphakeme futhi kunokwakheka kwefilimu okuhle nokusebenza kokwakhiwa kwe-resin ephezulu lokushisa njengezinto eziyisisekelo zezingubo ezimelana nokushisa, kanye nocwaningo lungathuthukisa kakhulu ukusebenza kwesisekelo esihlukahlukene. impahla ezimweni zokushisa eziphakeme izingulube, izigcwalisi, izinhlobo ezintsha.

I-powder yokuhlobisa yokuhlobisa

I-powder yokuhlobisa i-coating ibonakala ngokumboza ubuso obucacile bephethini ezintweni zokugqoka zibukeka kahle futhi zinemibala.Indlela yokwakheka kwe-powder yephethini kanye namapende asekelwe ku-solvent ahluke kakhulu, zombili izinhlobo zephethini nazo zihlukile. Impushana enamathelayo isebenzisa izici zayo zokuncibilika zomphumela wokuthungwa, ubujamo bephethini nobukhulu, ingxube yeresiphi, indlela yokulungiselela kanye nosayizi wezinhlayiyana zempushana.

Inhlanganisela yefomula ye-resin yokwenziwa, ama-ejenti okwelapha, ama-leveling agents, izingulube nezithasiselo ezihlukahlukene, yisici esiyinhloko ekwakhekeni kwamaphethini. Izindlela ezithuthukisiwe zokuba nemibono esemqoka elandelayo:

1. ukusetshenziswa kwama-polymers angahambelani ukukhiqiza isimo sokugeleza, ukwakheka komqondo wephethini onezinhlangothi ezintathu;
2. izinga lokuphulukisa elihlukile le-ejenti yokwelapha, ngenxa yomehluko wejubane lokulinganisa ukwakha imibimbi efanelekile;
3. Ngama-filler ahlukene, okuholela ekulinganisweni kwe-powder coating, ukuhluka kwe-gloss kanye ne-hue, okuholela kumphumela wokuthungwa;
4. imbudumbudu ehlukene kanye nomthunzi ohlukile wezingxube ze-metallic enamathela endaweni ehlukile, ama-engeli ahlukene, okuholela ekuhlukeni kwe-gloss ne-hue.

Ijazi lempushana le-flame retardant

I-polymer retardant ephezulu yelangabi ekhawulelwe, ukuze kuthuthukiswe ukubambezeleka komlilo kwama-polymer kubaluleke kakhulu ezindaweni eziningi zokusetshenziswa. Izembozo zempushana ezibushela ilangabi zomlilo nomsebenzi wokuvala umlilo. Ngokuthuthuka okusheshayo kwemboni yesimanje yama-elekthronikhi nezinto zikagesi, izidingo zokumboza ezivimba umlilo ziphuthuma kakhulu. Izinhlobo eziyinhloko zalokhu kuhlanganiswa yi-epoxy powder coating.

I-powder coating esebenzayo iwuhlobo olukhethekile lwezinto ezisebenzayo ezidlala indima ebaluleke kakhulu ezindaweni eziningi zesayensi nobuchwepheshe, ezokuvikela, izimboni kanye nezolimo.ral. Igebe namazwe angaphandle emikhiqizweni enjalo ithuthukiswe enkulu, kufanele siqinise imizamo yokuthuthukisa nokuthuthukisa umphumela osebenzayo we-ove ephakeme kakhulu.rall ukusebenza, izindleko eziphansi, ukudweba i-powder coatings esebenzayo ukuhlangabezana nezidingo zezidingo zokuthuthukiswa komnotho kazwelonke.
