Ukuphumelela okusha, i-bisphenol synthetic tannin engavinjelwe iholela ekuthuthukisweni okuluhlaza kwemikhiqizo yesikhumba

Ngokuqwashisa okwandayo kokuvikelwa kwemvelo, abathengi babeke phambili izidingo eziphakeme zokuphepha nokuvikelwa kwemvelo kwezinto zamakhemikhali. Embonini yokukhiqiza isikhumba, i-bisphenol A (BPA) nezinto ezifanayo ze-bisphenol zake zasetshenziswa kabanzi njengama-synthetic tanning agents, kodwa izinto ezinjalo zingase zibe izinsongo ezingaba khona emvelweni nempilo yabantu. Ngakho-ke, ukuthuthukiswa kwe-bisphenol synthetic tannins engavinjelwe sekuphenduke inkambo engenakugwenywa ekuthuthukisweni kwemboni. Lesi sihloko sizokwethula ngokuningiliziwe izinzuzo kanye nokusetshenziswa kwe-bisphenol synthetic tannins engavinjelwe, kanye nendima yayo ebalulekile ekuthuthukiseni okuluhlaza kwemikhiqizo yesikhumba.

Lahla i-bisphenol ekhawulelwe

I-Bisphenol A nezinto zayo ezifanayo ingase iphazamise ukukhiqizwa kwe-estrogen ezilwaneni futhi ibangele ubuthi bokuthuthuka ekuzaleni nasezinhlelweni ze-endocrine ngenxa yokufana kwazo kwesakhiwo ne-estrogen. Ngakho-ke, amazwe amaningi nezinhlangano ziye zabekela imingcele ukusetshenziswa kwezinto ezinjalo. Ukuthuthukiswa kwe-bisphenol synthetic tannins engavinjelwe kukhulula ukukhiqizwa kwemikhiqizo yesikhumba ezinkingeni zama-bisphenol avinjelwe futhi kuvula indlela entsha yokuthuthukiswa kwemboni.

Ukusebenza okuphezulu

I-bisphenol synthetic tannins engakhawulelwe ifinyelela ukusebenza okuphezulu kwemvelo kuyilapho igcina izakhiwo zangempela zama-synthetic tanning agents. Akukwazi nje ukuthuthukisa ngempumelelo ukuqina, ukugcwala kanye nokumelana nokukhanya kwesikhumba, kodwa futhi kunciphise ukukhululwa kwe-formaldehyde yamahhala, ukunciphisa umthelela omubi emvelweni kanye nempilo yabantu.

Uhla olubanzi lwezinhlelo zokusebenza

I-bisphenol synthetic tannins engakhawulelwe inezinhlobonhlobo zezinhlelo zokusebenza. Embonini yokushuka, ingasetshenziswa ekushukeni isikhumba, ukubuyisela kabusha kanye nezinqubo zokuqeda, futhi ifanele izinhlobo ezihlukahlukene zemikhiqizo yesikhumba. Ngaphezu kwalokho, ingasetshenziswa futhi ekucubunguleni imicu, izindwangu nezinye izinto, futhi inamathuba emakethe abanzi.

Izidingo ezithuthukisiwe zokuvikela imvelo

Njengoba ukuqwashisa ngemvelo emhlabeni wonke kuqhubeka nokwanda, ohulumeni nezinkampani emhlabeni wonke baye baqinisa izidingo zabo zokuvikelwa kwemvelo. Ukuthuthukiswa nokusetshenziswa kwe-bisphenol synthetic tannins engakhawulelwe kuvumelana nale nqubo yentuthuko futhi kuhlangabezana nezimfuneko eziphakeme zabathengi zokuvikelwa kwemvelo, ezempilo nokuphepha.

Inketho engenakugwemeka yokuthuthukiswa kwezimboni

Imboni yezimpahla zesikhumba ibhekene nezinselelo zokusimama. Ukusetshenziswa kwe-bisphenol synthetic tannins engakhawulelwe kuzosiza ukukhuthaza ukuthuthukiswa kwezimboni zemboni yemikhiqizo yesikhumba futhi kuzuzwe ukukhiqizwa okuluhlaza kanye nentuthuko esimeme. Lokhu akukwazi nje ukuthuthukisa ukuncintisana kwamabhizinisi, kodwa futhi kuletha intuthuko enempilo nehlala njalo kuyo yonke imboni.

Ukuqamba okusha kushayela intuthuko

Ukuthuthukiswa okuyimpumelelo kanye nokusetshenziswa kwe-bisphenol synthetic tannins engakhawulelwe kubonisa indima ebalulekile yokuqanjwa kabusha kwezobuchwepheshe ekukhuthazeni inqubekelaphambili yemboni. Ngokuqhubeka nokusungula izinto ezintsha kanye nocwaningo nentuthuko, siyakwazi ukwephula imikhawulo yezinqubo zendabuko, sizuze ukukhiqizwa okuluhlaza kanye nentuthuko esimeme, futhi sifake umfutho omusha ekuthuthukisweni kwemboni yesikhathi esizayo.

Ukuthuthukiswa kanye nokusetshenziswa kwe-bisphenol synthetic tannins engakhawulelwe kuyindlela ebalulekile ukuze imboni yemikhiqizo yesikhumba ifinyelele ekuthuthukisweni okuluhlaza. Ayigcini nje ngokususa inkathazo ye-bisphenol ekhawulelwe, ithuthukisa ukusebenza kwemvelo kanye nekhwalithi yokusebenza kwemikhiqizo, kodwa futhi iletha amathuba ebhizinisi amaningi kanye nendawo yentuthuko emabhizinisini. Ekuthuthukisweni okuzayo, sibheke ngabomvu ukubona izinto ezintsha ezengeziwe zesayensi nezobuchwepheshe zisetshenziswa embonini yemikhiqizo yesikhumba ukuze kuthuthukiswe intuthuko esimeme kanye nokuthuthukiswa kokuqamba okusha kwemboni.
