Kungani i-Silica ye-Grade Yokudla Ikhethwa ukuze Isetshenziswe ku-Sawoti Esidliwayo eNingizimu Melika Enomswakama? Ukukhetha I-Grade, I-Dosage & Ukuhambisana

Ukunqwabelana kukasawoti sekuyisikhathi eside kuyinkinga evamile kubakhiqizi nabasabalalisi bakasawoti kulo lonke elaseBrazil, e-Argentina, ePeru nakwamanye amazwe aseNingizimu Melika. Izinga lokushisa eliphezulu nomswakama, ukuthuthwa kwebanga elide emhlabeni nasolwandle, kanye nokugcinwa ezindaweni eziningi kufaka izidingo eziqinile ekusebenzeni kokuvimbela ukunqwabelana kukasawoti. Phakathi kwama-anticaking agents ahlukahlukene, i-silica yezinga lokudla isiphenduke ukukhetha okuyisisekelo embonini kasawoti yaseNingizimu Melika ngenxa yokusebenza kahle kwayo, ukuphepha nokuhambisana nemithetho.

Ama-anticaking agents endabuko afana ne-tricalcium phosphate ne-magnesium carbonate ayeka ukusebenza ngokushesha lapho umswakama wendawo udlula u-65%. Isakhiwo esinezimbobo se-silica simunca umswakama okhululekile ngokuqhubekayo, sigcine usawoti ugeleza ngokukhululekile izinyanga ezi-3–6 ngisho nangesikhathi sezimvula zaseNingizimu Melika futhi sivikele ukubukeka kwawo okuphelile.

Umthamo ojwayelekile kusawoti ngu-0.1%–0.3%, ophansi kakhulu kunezinye izinto ezivimbela ukunqwabelana. Ihlakazeka ngokulingana nezinhlayiya zikasawoti ngaphandle kokunqwabelana kwendawo futhi ngeke kuthinte ubumhlophe noma ukunambitheka kukasawoti. Ezitshalweni ezinkulu zikasawoti, ukwengezwa okuncane kungaxazulula izinkinga zokunqwabelana kuyo yonke inqwaba.

I-MERCOSUR igunyaza i-silica njengesithako esivimbela ukunqwabelana sikasawoti odliwayo ngomkhawulo ongu-1.5%. Iphinde ihambisane nezindinganiso zokudla ze-Codex futhi ayidingi imvume eyengeziwe ukuze isakazwe emazweni aseNingizimu Melika.

Khetha amazinga anokumunca uwoyela okuphezulu ukuze kwenyuse ukumunca umswakama ekugcinweni okunomswakama kanye nokuthutha olwandle

Fanisa usayizi wezinhlayiya zikasawoti ukuze ugweme ukwehlukana futhi uqinisekise ukuxubana okufanayo

Amazinga ezinsimbi ezisindayo ne-arsenic ngaphansi kwemikhawulo yomthetho, i-iron ephansi, awekho amachashaza amnyama ukuze kugcinwe ukumhlophe kasawoti

Umthamo onconywayo: 0.1%–0.2% kasawoti ocwengekile; 0.2%–0.3% kasawoti wasolwandle onomswakama ophezulu kanye nosawoti onezithako. Umthamo wokugcina kufanele uqinisekiswe izivivinyo zaselabhorethri ngokuya ngomswakama wendawo, ukupakisha nomjikelezo wokugcina.

Isincomo senqubo: Ukuxuba okomile ngemuva kokuba usawoti womile ngokuphelele futhi upholile. Gwema ukuvula amaphakethe nokuphakela ngaphansi kwezimo ezinomswakama ukuze uvimbele ukumuncwa komswakama ngaphambi kwesikhathi kwe-silica. Gcina izimpahla ezindlini zokugcina ezomile futhi uphinde uvale amaphakethe alimele ngokushesha.

Lungiselela imibhalo kusenesikhathi ye-silica esetshenziswa kusawoti ethunyelwa eBrazil naseNingizimu Melika:

I-silica esezingeni lokudla ayiyona nje isithako esilula. Iyisithako esisebenzayo esisiza abakhiqizi kamasawoti baseNingizimu Melika ukuqinisekisa ikhwalithi yomkhiqizo ophelile, ukunciphisa ukulahlekelwa kwezokuthutha kanye nokugcina isithunzi semakethe yokugcina. Ukukhetha izinga elifanele, ukulawula umthamo onembile kanye nokuthenga okuhambisana nemithetho kuvumela ikhwalithi kamasawoti engaguquki kulo lonke uchungechunge lokuhlinzeka olushisayo nolunomswakama eNingizimu Melika.
