Sebenzisa Le pigment ingenye i-benzimidazolone ebomvu nephuzi enesakhiwo esifakwe emakethe eminyakeni yamuva, ene-hue angle engu-66.5 degrees (1/3S.D., HDPE), esetshenziselwa ukufaka umbala we-Polyolefin, akukho ukuguquguquka kosayizi, nokusimama okuhle kakhulu kokushisayo. nokushesha okukhanyayo, ukumelana nokushisa kufika ku-300 ℃, ukushesha okukhanyayo kuya ebangeni lesi-7-8. Isetshenziswa kakhulu emibala yepulasitiki, ikakhulukazi ekusetshenzisweni kwezinga lokushisa okuphezulu kwe-resin, njenge-PS, ABS, PE, njll.; Ibuye isetshenziselwe i-viscose fiber kanye nombala wepende.

Isingeniso

I-Yellow 181 i-pigment yemvelo enegama lekhemikhali le-phenoxymethyloxyphenylazolizoyl barium.

 

I-Yellow 181 pigment inombala ophuzi ogqamile futhi inokuqina okuhle kokukhanya nokuqina. Imelana kakhulu nezincibilikisi kanye nokukhanya, futhi ayijwayele ukufiphala nokufiphala. I-Yellow 181 nayo inokushisa okuhle nokumelana namakhemikhali.

 

I-Yellow 181 isetshenziswa kabanzi njengombala ezimbonini ezinjengoyinki, amapulasitiki, okokunamathela, nenjoloba. Umbala wayo ophuzi ogqamile wengeza ukukhanga kanye nobuhle bomkhiqizo. I-Yellow 181 ibuye isetshenziswe ngokujwayelekile ekudayeni izindwangu, ubuciko bokupenda nokuphrinta.

 

Ukulungiswa kwe-Huang 181 kuvame ukwenziwa ngezindlela zamakhemikhali zokwenziwa. Ngokuqondile, i-phenoxymethyloxyphenyl triazole iqala ukuhlanganiswa, bese isabela nge-barium chloride ukuze yakhe umbala ophuzi ongu-181.

Gwema ukuhogela uthuli oluphuzi 181 noma isixazululo, futhi ugweme ukuthintana kwesikhumba namehlo. Lapho ugcina futhi uphatha Okuphuzi 181, imithetho yendawo kufanele igcinwe, futhi kufanele igcinwe endaweni eyomile, engenawo umoya. Uma ugwinye ngephutha noma uthintana ne-Huang 181, kufanele uthole usizo lwezokwelapha ngokushesha.
