Izinhlobo ezahlukene ze-titanium dioxide ezinhlobonhlobo ze-powder coating

Ukufaka imininingwane yomncintiswano embonini ye-powder coating, upende wepende ufakiwe kusixhumanisi sophenyo. I-polyester epoxy i-powder coatings ukuthuthukisa ikhwalithi yomsebenzi, futhi i-titanium dioxide ephezulu ibalulekile ngoba siyaqaphela ukuthi i-titanium dioxide dipolyester isibe yingxenye yekhwalithi yemikhiqizo yokumboza i-epoxy powder.
I-polyester epoxy powder coating ibe omunye wemikhiqizo ebaluleke kakhulu phakathi kwemikhiqizo eminingi yokugqoka i-powder ngenxa yokusebenza kwayo okuhle kakhulu. Yakhiwe nge-polyester resin, i-epoxy resin, i-filler kanye ne-axiliary. Ngokusho kwenhlangano yochwepheshe be-epoxy resin industry, i-polyester-epoxy powder coating pigments ihlanganisa izinhlobonhlobo ze-titanium dioxide, i-chrome yellow, i-iron green, i-iron oxide ebomvu, i-iron oxide yellow, i-yellow G esheshayo, i-phthalocyanine eluhlaza, i-phthalocyanine blue BGS, i-BBN ebomvu, i-F3RK ebomvu, ebomvu ehlala njalo, i-F5RK ebomvu engapheli nezinye izinhlobo ezimnyama ze-carbon. Impushana emhlophe iwumbala omhlophe ovame ukusetshenziswa ezimpahleni ezimhlophe ze-polyester epoxy powder. Ngokwefomula evame ukusetshenziswa emhlophe ye-polyester epoxy powder coating, ifanele izinhlobo ezahlukene ze-titanium dioxide, A0101, R940, R902, R244, R930, R706.

Ngokuqhathanisa ukuhlolwa, izinhlobo ezahlukene ze-titanium dioxides polyester epoxy powder coatings zingatholakala. Izinhlobo ezahlukene ze-titanium dioxide, ngenxa yezinqubo ezihlukene zokukhiqiza, amafomu ekristalu nezindlela zokwelashwa kwendawo, ukwakheka kwamakhemikhali awo kanye nezakhiwo kunomthelela omkhulu ekusebenzeni kabusha kwamakhemikhali kanye nokuhlakazeka kwezingubo zempuphu ye-polyester-epoxy, kanye nesikhathi sejeli se-powder coatings. , futhi izinga lokuncibilika kwe-ncibilika liphinde libe nomthelela ku-fluidity, isicwebezelisi, umbala kanye nokumelana nomthelela we-coating. Idatha ibonisa ukuthi i-powder coating elungiselelwe i-anatase titanium dioxide (A0101) inomsebenzi ophezulu kune-powder coating elungiselelwe uhlobo lwe-rutile (uhlobo lwe-R) i-titanium dioxide, enesikhathi esifushane se-gel, ukuncibilika okuhle kokuncibilika, ukubunjwa okungalungile kokugqoka kanye ne-gloss ephansi. Kukhona futhi umehluko obalulekile ezinkomba zobuchwepheshe phakathi kwe-rutile titanium dioxide.

Ngokusho kwezidingo zokusebenza ze-powder coatings, kubaluleke kakhulu ukuhlangabezana nezidingo zokusebenza zokugqoka ezihlukahlukene ze-powder coatings kanye ne-titanium dioxide. Ucwaningo luye lwabonisa ukuthi i-matte polyester epoxy powder coatings, i-anatase titanium dioxide kanye ne-rutile titanium dioxide yenza upende uthambekele kakhulu ekushintsheni umbala noma ophuzi, ngakho-ke lolu hlelo lokumboza luwukusetshenziswa okungcono kakhulu kwe-rutile titanium dioxide.
