Iindidi ezahlukeneyo ze-titanium dioxide kuhlobo olwahlukileyo lokugquma umgubo

Ukufaka iinkcukacha zokhuphiswano kwishishini le-powder coating, iingubo zepeyinti zibandakanyiwe kwikhonkco lophando. Polyester epoxy Ipeyinti ukuphucula umgangatho womsebenzi, kwaye i-titanium dioxide ephezulu ibalulekile kuba siyaqonda ukuba i-titanium dioxide dipolyester ibe yinxalenye yomgangatho weemveliso zokugqoka i-epoxy powder.
I-Polyester epoxy powder coating ibe yenye yezona mveliso zibalulekileyo phakathi kweemveliso ezininzi zokugquma umgubo ngenxa yokusebenza kwayo kakuhle. Ihlanganiswe ne-polyester resin, i-epoxy resin, i-filler kunye ne-axiliary. Ngokombutho weengcali ze-epoxy resin industry, i-polyester-epoxy powder coating pigments ibandakanya iindidi ze-titanium dioxide, i-chrome yellow, i-iron eluhlaza, i-iron oxide ebomvu, i-iron oxide yellow, i-yellow G ekhawulezayo, i-phthalocyanine eluhlaza, i-phthalocyanine blue BGS, i-BBN ebomvu, obomvu, obomvu osisigxina F3RK, obomvu osisigxina F5RK kunye nezinye iintlobo ze-carbon black. Umgubo omhlophe usetyenziswa ngokuqhelekileyo kwibala elimhlophe kwipolyester emhlophe epoxy yomgubo. Ngokwendlela eqhelekileyo esetyenziswayo emhlophe yepolyester epoxy powder yokugquma ifomula, ifanelekile kwiindidi ezahlukeneyo ze-titanium dioxide, i-A0101, i-R940, i-R902, i-R244, i-R930, i-R706.

Ngokuthelekisa uvavanyo, iintlobo ezahlukeneyo ze-titanium dioxide i-polyester epoxy powder coatings inokufunyanwa. Iindidi ezahlukeneyo ze-titanium dioxide, ngenxa yeenkqubo ezahlukeneyo zokuvelisa, iifom ze-crystal kunye neendlela zokunyanga komhlaba, ukubunjwa kwazo kweekhemikhali kunye neempawu zinempembelelo enkulu kwi-chemical reactivity kunye ne-dispersibility ye-polyester-epoxy powder coatings, kunye nexesha le-gel le-powder coatings. , kunye nenqanaba lokunyibilika kokunyibilika kwakhona kuchaphazela ubumanzi, iglosi, umbala kunye nokuchasana kwempembelelo yengubo. Idatha ibonisa ukuba i-powder powder elungiselelwe yi-anatase titanium dioxide (i-A0101) inomsebenzi ophezulu kune-powder powder elungiselelwe uhlobo lwe-rutile (uhlobo lwe-R) i-titanium dioxide, kunye nexesha elifutshane le-gel, ukunyibilika okulungileyo, ukubunjwa okungahambi kakuhle kunye ne-gloss ephantsi. Kukwakho umahluko obalulekileyo kwizalathisi zobugcisa phakathi kwerutile titanium dioxide.

Ngokweemfuno zokusebenza zepowder coatings, kubaluleke kakhulu ukuhlangabezana neemfuno zokusebenza zokugquma kweengubo ezahlukeneyo zomgubo kunye ne-titanium dioxide. Uphononongo lubonise ukuba i-matte polyester epoxy powder coatings, i-anatase titanium dioxide kunye ne-rutile titanium dioxide yenza ipeyinti ikwazi ukuguquguquka okanye i-yellowing, ngoko ke le nkqubo yokugqoka iyona ndlela yokusetyenziswa kwe-rutile titanium dioxide.
