Izinhlobo zezithasiselo zokuhlanganisa ezisetshenziswa kuPowder Coating noma upende

Kunezinhlobo ezine zezithasiselo zokuhlanganisa ezisetshenziswa ku I-Powder Coating Powder noma Upende.

• Ama-silica

Emkhakheni obanzi wama-silicas atholakalayo wokuhlanganisa kukhona amaqembu amabili ahlukene ngokwenqubo yawo yokukhiqiza. Enye inqubo ye-hydro-thermal, ekhiqiza i-silicas ene-morphology ethambile. Ngokusebenzisa imikhiqizo yenqubo ye-silica-gel ingatholakala ene-morphology enzima. Zombili izinqubo ziyakwazi ukukhiqiza i-silica evamile futhi ngemva kwemikhiqizo eselashiwe. Ngemva kokwelashwa kusho ukuthi i-silica surface ingashintshwa kancane nge-organic (wax) noma izinto ezingaphili. Uma kuqhathaniswa nama-agent we-silica-gel matting, i-silica eguquliwe inosayizi wezinhlayiyana ohlukile, ukusatshalaliswa kosayizi wezinhlayiyana, kuvolumu yembotshana. I-Hydrothermal matting agents ihlukile ngosayizi wezinhlayiyana nokusabalalisa. Singathola nezinto ezingelashiwe nezilashwe. Njengamanje kunomkhiqizo owodwa kuphela odumile ekusetshenzisweni okuqondile, okhiqizwa ngokwenqubo ye-pyrogenic, futhi ubonisa ukusebenza kahle okuphezulu kakhulu kokulinganisa, ikakhulukazi ezinhlelweni ezisekelwe emanzini.

Ama-Synthetic Aluminium silicates asetshenziswa kumapende e-emulsion ikakhulukazi njengesandiso sekhwalithi ephezulu ukuze ingxenye ye-Titandioxyd ingene esikhundleni. Kodwa-ke, zingase futhi zisetshenziselwe ukunikeza umphumela wokulinganisa olinganayo kupende omisiwe we-emulsion. Ezinhlelweni ezinde zamafutha e-Alkyd zisebenza njenge-ejenti yokuhlanganisa, kodwa kufanele zihlakazwe nge-pigment kanye nezigcwalisi. Ama-silica ama-matting asetshenziswa ezinhlelweni zokumboza zonke, nakuba kungenjalo kuma-powder coatings.

• Ama-wax

Namuhla, kunezinhlobonhlobo ezihlukahlukene zama-wax emakethe. Ama-wax asetshenziswa kakhulu okugcoba noyinki asekelwe ku-Polyethylene, Polypropylene, Carnauba, Amid. Imikhiqizo ye-wax esekelwe ku-Polytetrafluorethylene PTFE iphinde isetshenziswe njengama-matting agents.

Ngokungafani nama-silicas, ama-wax aguqula izici ezingaphezulu zefilimu kapende ngokuntanta phezulu. Lesi simo sithinta izici ezilandelayo: izinga le-matt / gloss; ukumelana nokushelela nokuma; anti blocking kanye nezakhiwo zokuhuzuka, i-anti settle kanye ne-surface tension.

Iningi lemikhiqizo ilethwa njengemikhiqizo ye-micronized, etholakala ezinhlobonhlobo eziningi zokugxila ezisekelwe kuma-emulsions we-wax. Ukusabalalisa kuyehluka kuye ngobukhulu bezinhlayiyana kanye nokusabalalisa usayizi wezinhlayiyana.

• Amafayili

Nakuba ukubukeka kwamapende kushintsha ngokungezwa kwezithasiselo zokuhlanganisa ezishiwo ngaphambili, ukusebenza akuthinteki. Ngokusebenzisa izigcwalisi ezithile sikhulisa ngokucacile i-Pigment-Volume-Concentration kapende ehilela yonke imiphumela engemihle eyishoyo. Yingakho le ndlela yokuhlanganisa ikhawulelwe ezinhlelweni zokupenda ezinemibala ephansi kuphela, ezisezingeni eliphansi.

Ama-filler anokusabalalisa usayizi wezinhlayiyana ezincane ngokukhethekile kufanele ahlakazeke kanye nama-pigments. Ukulungisa idigri yegloss edingekayo i-praksis ukuyilungisa ngokusebenzisa i-stir in Silica ekupheleni kwenqubo yokukhiqiza upende.

• Izinto Eziphilayo

Ngamasu esimanje okugaya kungenzeka ukugaya izinto zepulasitiki ezisekelwe ikakhulukazi ku-Poly methyl urea resin. Imikhiqizo enjalo inethonya eliphansi ku-viscosity, ibonisa ukuzinza kwezinga lokushisa kuze kufike ku-200 ° C, inokumelana okuhle kwe-solvent, futhi kulula ukuyihlakaza.

Sekukonke, Zonke izithasiselo zokuhlanganisa ezisetshenziswa embotsheni yempushana noma endaweni kapende, zinezinzuzo kanye nezinzuzo zazo.
