Indlela Yokukhetha I-Powder Efanele Yemikhiqizo Yakho
Indlela Yokukhetha I-Powder Efanele Yemikhiqizo Yakho Ukukhetha isistimu ye-resin, i-hardener, kanye ne-pigment kuyisiqalo ekukhetheni izakhiwo umuntu angazidinga ekuqedeni. Ukulawulwa kokucwebezela, ukushelela, izinga lokugeleza, izinga lokwelapha, ukumelana ne-ultra violet, ukumelana namakhemikhali, ukumelana nokushisa, ukuguquguquka, ukunamathela, ukumelana nokugqwala, ukuqina kwangaphandle, amandla okubuyiselwa nokusebenzisa kabusha, ukusebenza kahle kokudluliswa kokuqala kokuqala, nokunye, okunye wezinto okufanele zicatshangelwe uma kukhona into entshaFunda kabanzi …
I-TGIC esikhundleni samakhemikhali ku-powder coating-Hydroxyalkylamide(HAA)
I-Hydroxyalkylamide(HAA) TGIC Replacement chemistries Njengoba ikusasa le-TGIC lingaqinisekile, abakhiqizi bafuna ukumiselela okufanayo. Imithi yokwelapha ye-HAA efana ne-Primid XL-552, ethuthukiswe futhi ephawulwe yi-Rohm kanye ne-Haas, yethuliwe. Umphumela oyinhloko kulokho okuqinile ukuthi, njengoba indlela yokwelapha iwukusabela kokujiya, amafilimu akha ugqinsi oludlula amamitha angu-2 ukuya kwangu-2.5 (ama-microns angama-50 kuye kwangama-63) angase abonise ukukhipha umoya, ukuphina, nokugeleza nokungalinganisi kahle. Lokhu kuyiqiniso ikakhulukazi uma leziFunda kabanzi …
Ezinye izici ezibalulekile zokuwohloka kwe-polyester coating
Ukuwohloka kwe-polyester kuthinteka emisebeni yelanga, ingxube ye-photocatalytic, amanzi nomswakama, amakhemikhali, umoya-mpilo, i-ozone, izinga lokushisa, imihuzuko, ukucindezeleka kwangaphakathi nangaphandle, kanye nokufiphala kwe-pigment.Kukho konke lokhu, lezi zici ezilandelayo, zonke ezikhona esimweni sezulu sangaphandle, yilezi: Okubaluleke kakhulu ekucekeleni phansi kokumboza: umswakama, amazinga okushisa, i-oxidation, imisebe ye-UV. I-Moisture Hydrolysis yenzeka lapho ipulasitiki ichayeke emanzini noma kumswakama.Lokhu kusabela kwamakhemikhali kungase kube isici esiyinhloko ekuwohlokeni kwama-polymers e-condensation njenge-polyester, lapho iqembu le-esterFunda kabanzi …
Izimfuneko zokumboza impushana phezu kokufakwa uthayela kwediphu elishisayo
Ukucaciswa okulandelayo kuyanconywa: Sebenzisa i-zinc phosphate pretreatment uma ukunamathela okuphezulu kuyadingeka. Ubuso kufanele buhlanzeke ngokuphelele. I-Zinc phosphate ayinawo isenzo sokuhlanza futhi ngeke isuse amafutha noma inhlabathi. Sebenzisa i-iron phosphate uma ukusebenza okujwayelekile kuyadingeka. I-iron phosphate inesenzo esincane sokuhlanza futhi izosusa inani elincane lokungcoliswa kwendawo. Okusetshenziswa kakhulu emikhiqizweni efakwe ngaphambili. Umsebenzi wokushisa ngaphambi kokufaka i-powder. Sebenzisa 'degassing' grade polyester powder coating kuphela. Hlola ukuphulukiswa okulungile nge-solventFunda kabanzi …
