Intshayelelo yemibala

Imibala yohlulwe kakhulu ibe ziindidi ezimbini:ibalakwayeiidayi. Ii-pigments zinokwahlulwa zibeii-pigments eziphilayokwayei-pigments ye-inorganicngokobume bazo. Idayi ziikhompawundi zendalo ezinokuthi zisetyenziswe kuninzi lwezinyibilikisi kunye neeplastiki ezidayiweyo, ezinenzuzo ezifana noxinaniso oluphantsi, amandla aphezulu ombala, kunye nokungafihli kakuhle. Nangona kunjalo, ulwakhiwo lwabo lweemolekyuli ngokubanzi luncinci kwaye ukufuduka kudla ngokubakho ngexesha lokufaka imibala.

ibala

Imibala ingahlulwa ngokubanzi ibe yimibala kunye nedayi. Ii-pigments zizinto ezinika imathiriyeli umbala ngokufunxa ngokukhetha kunye nokubonakalisa ukukhanya. Zinokwahlulwa kwakhona zibe yi-organic pigments (ephuma kwi-carbon-based compounds) kunye ne-inorganic pigments (ezenziwe kwiiminerali). Idayi yona, zizinto eziphilayo ezinyibilikayo kwizinyibilikisi kwaye zinokusetyenziselwa ukufaka imibala kwizinto ezahlukeneyo, kuquka iiplastiki. Baneenzuzo zokuxinana okuphantsi, amandla okuthayela aphezulu, kunye nokungafihli kakuhle. Nangona kunjalo, ngenxa yobungakanani bayo bemolekyuli encinci, iidayi zidla ngokufuduka okanye zophe ngaphandle kwezixhobo ezigqunywe kuzo, ngakumbi phantsi kweemeko ezithile zokusingqongileyo, ezinje ngobushushu obuphezulu okanye ukuchanabeka kwimichiza ethile.

Ngokutsho kohlalutyo lweengcali zengqondo, i-83% yombonoukubaabantu bafumana kwihlabathi langaphandleis ngokusekelwe kwiimvakalelo zaboleyoivela kwimbono yokubona. Kuyabonakala ukuba ukubaluleka kwembonakalo yemveliso, ngakumbiumbala wemvelisoukubonakalae, ibaluleke ngokukhethekileyo. Ngokumalunga neemveliso zesondlo, nokuba abasebenzisi basebenzisa imveliso ethile yokutya okanye hayi, umbala wenkangeleko yesondlo udlala indima ebalulekileyo yokumisela.

iidayi zombala

Iisicelozemibala ziya zixhaphake kakhulu kushishino lwezondlo lwangoku kunye nokufuywa kwezilwanyana kunye ne-aquaculture.Kukho izizathu ezibini ngolu hlobo lulandelayo: okokuqala, ukutshintsha umbala wesondlo ngokusebenzisa imibala. Ingakumbi ekusetyenzisweni okwandisiweyo kwezithako zokutya ezingezizo ezemveli, ukongeza i-colorants ukugquma imibala engalunganga yezithako ezithile zokutya ezingezizo ezesintu (ezifana nerapeseed meal),ke ngoko ukuibonelele kubasebenzisi bemikhwa yengqondo, kunye nokwandaeukhuphiswano lwemarike.Kwangaxeshanye, ikwadlala indima ekuvuseleleni umdla wokutya kunye nokukhuthaza ukutya.Imibala edlala le ndima inokubizwa ngokuba yimibala yokutya.
