Amadayi abhekisela ezintweni ezingadaya imibala egqamile neqinile ezindwangu zefayibha noma kwezinye izinto. Ngokwezakhiwo nezindlela zokusebenzisa amadayi, angahlukaniswa ngezigaba ezincane ezifana namadayi ahlakazekile, amadayi asabelayo, amadayi esibabule, amadayi e-vat, amadayi e-asidi, amadayi aqondile, amadayi e-solvent, amadayi ayisisekelo njll. Amadayi ahlakazekile yiwona akhiqizwa kakhulu phakathi kwazo zonke lezi zinhlobo zamadayi zesigaba esincane. Futhi yiwona kuphela udayi ongadaya futhi uphrinte kumafayibha e-polyester (i-polyester). Izimboni ezikhuphukayo zezimboni zamadayi zimboza amasimu amakhemikhali kaphethroli namakhemikhali amalahle; Izimboni eziphakathi nendawo zinomthwalo wemfanelo wokulungiselela amadayi aphakathi nendawo kanye nokulungiswa kwamadayi, anomthwalo wemfanelo wokukhiqiza amadayi, ukulawulwa kwekhwalithi kanye nokuthuthukiswa komkhiqizo; Ngaphansi, isetshenziswa kakhulu embonini yokunyathelisa nokudaya, kanti umkhakha wabathengi wokugcina ungumkhakha wezindwangu nezingubo.
Ngokusho kwedatha evela kwiNational Bureau of Statistics, inani lamabhizinisi angaphezu kosayizi oqokiwe embonini yodayi eShayina ngo-2022 lalingu-277, ukwanda okungu-9 uma kuqhathaniswa no-2021. Inani eliphelele lomkhiqizo wale mboni lifinyelele kuma-yuan ayizigidigidi ezingu-76.482, kanye nempahla iyonke engu-yuan ayizigidigidi ezingu-120.37, imali engenayo yokuthengisa engu-yuan eyizigidigidi ezingu-66.932, kanye nenzuzo iyonke engu-yuan eyizigidigidi ezingu-5.835. Kusukela ekuguqulweni nasekuvulekeni, ikakhulukazi kusukela ngawo-1990, ngokudluliselwa kwezimboni zezingubo, izindwangu, ifayibha, kanye nokunyathelisa nokudaya emhlabeni, imboni yodayi yaseShayina ithuthuke ngokushesha, kancane kancane yaba ngelinye lamazwe amakhulu emhlabeni akhiqiza udayi. Ngokusho kwedatha evela kwi-China Dye Industry Association, ukukhiqizwa kukazwelonke kwemboni yodayi ngo-2022 kwakungamathani angu-864000, ukwanda konyaka nonyaka okungu-3.47%.
AMAKHEMIKALI OKUPHUMA KWELANGA anganikeza amakhasimende izinhlobo ezahlukene zodayi. Ngokwezindlela ezahlukene zokusebenzisa amakhasimende, singahlinzekaudayi wephepha, udayi wezindwangu, udayi weyinki, amadayi epulasitiki, udayi wokhuni, udayi wesikhumba, njll.
Uma unesithakazelo kumadayi asezingeni eliphezulu, sicela usithinte.
