Indlela Yokukhetha I-Powder Efanele Yemikhiqizo Yakho

Indlela Yokukhetha Okufanelekile Ukugqoka i-Powder Ngemikhiqizo Yakho

Ukukhethwa kwesistimu ye-resin, i-hardener, kanye ne-pigment kumane 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 kokudlulisa okokuqala ngqa, nokunye, okunye wezinto okufanele zibhekwe lapho kukhiqizwa noma iyiphi impahla entsha.
I-Thermosetting powder coating ihlukaniswa ngamaqembu amahlanu ayisisekelo amakhemikhali i-Epoxy, i-Epoxy-polyester, evame ukubizwa ngokuthi i-Hybird, i-Polyester Urethanes, i-Polyester-TGIC, ne-Acrylic

Izembatho ze-Urethane-Polyester zisetshenziswa kangcono kwizicelo zefilimu elincanyana (1.0-3.0 mil). Ngaphezulu kwalolu hlu, ama-Urethanes angase athambekele ekubeni yinkungu, ukuphuma umoya noma ukubhoboza ngenxa yenani elincane lokuguquguquka eliphuma kumsebenzeli olaphayo ohlelweni. Kodwa-ke, uma imingcele yokuqina ilawulwa, ama-Urethane ahlinzeka ngendawo yefilimu eqinile, ehlala isikhathi eside enobushelelezi obuhle kakhulu, ukuguquguquka, nezici zesimo sezulu sangaphandle.

Ama-powder ochungechunge lwe-epoxy aphawuleka ngokumelana kwawo okuhle kakhulu namakhemikhali nokugqwala. Lezi ezinengilazi zinebanga elibanzi le-latitude yokubunjwa ngoba zingenziwa ngokwezifiso ukuze zihlangabezane nefilimu ewugqinsi esebenzayo noma emincane yefilimu yokuhlobisa ukusetshenziswa kokuphela. Eyaziwa njengendawo eguquguqukayo kodwa eqinile, okuwukuphela komphumela kuma-Epoxies ukuntula kwawo ukubekezelela okuluhlaza okwesibhakabhaka.
I-Epoxy Polyester chemistries, noma i-Hybrid, ibonisa ezinye zezindlela ezingcono kakhulu zokudlulisa zonke izigqoko ze-thermoset powder.Kwezinye izimo, zingase ziguquguquke njengezinhlobo ze-Epoxy, kodwa zilahlekelwe ubulukhuni nokumelana kwamakhemikhali ngenxa yengxenye ye-Polyester.

Ama-Acrylic amelela ingxenye encane kakhulu yemakethe ye-thermoset ngenxa yenani labahlinzeki beresin kanye nabakhiqizi bempushana be-acrylic, kanye nezinkinga zokungahambisani kwesinye isikhathi okuhlangatshezwana nazo lapho kusetshenziswa lezi zinhlelo ngokushintshana namanye amakhemikhali e-thermoset. Kodwa-ke, ama-Acrylic powders ahlanzekile abonakala ngokubukeka kwefilimu okuhle kakhulu, ukuguquguquka, nobulukhuni. Ziphinde zihlukaniswe njengezinhlelo zezulu.

I-Polyester TGIC imele indawo ekhula ngokushesha kubuchwepheshe be-thermoset. Lokhu kukhula kungase kubangelwe i-ove ye-chemistryrall Izilinganiso zokusebenza ezimpahleni zomzimba namakhemikhali, ukusebenza kahle kokusebenza noma ukudlulisa, nokumelana okuhle kakhulu kwe-Ultraviolet. Futhi, i-TGIC-Polyesters ingasetshenziswa kumafilimu aminyene ngokuqhathaniswa (i-6+ mils) ngaphandle kokufakwa okuguquguqukayo noma ukuphuma kwegesi.
