4,4′ – I-DIHYDROXYDIPHENYLMETHANE: Isetshenziswa Kabanzi Kodwa Izingozi Zempilo Ziyakhathaza

Ikhemikhali esetshenziswa kabanzi emikhakheni eminingi yezimboni kanye nokuphila kwansuku zonke idonsela ukunaka okwandayo emphakathini kanye nasemphakathini wesayensi.

I. 4,4′ – DIHYDROXYDIPHENYLMETHANEinezinhlobo eziningi zezicelo. Emkhakheni wezimboni, i-4,4′ – DIHYDROXYDIPHENYLMETHANE iyinto eluhlaza eyinhloko yokukhiqiza ama-resin epoxy asebenza kahle kakhulu. Lolu hlobo lwe-resin epoxy lusetshenziswa kabanzi embonini ye-elekthronikhi kanye nemishini kagesi. Isibonelo, enkambisweni yokukhiqiza amabhodi wesekethe aphrintiwe (ama-PCB), ama-resin epoxy ohlobo lwe-4,4′ – DIHYDROXYDIPHENYLMETHANE, anezakhiwo zawo ezinhle kakhulu zikagesi, zemishini kanye nezingamelani nokushisa, angaqinisekisa ukusebenza okuzinzile kwezingxenye ze-elekthronikhi ezindaweni zokusebenza eziyinkimbinkimbi. Embonini yokwakha, izinto eziqukethe i-4,4′ – DIHYDROXYDIPHENYLMETHANE nazo zidlala indima ebalulekile. Zisetshenziselwa ukukhiqiza izembozo nezinamathiselo ezisebenza kahle kakhulu, ezinganikeza ukuqina okuhle nokunamathela, okwenza isakhiwo sesakhiwo sizinze kakhulu kanye nokuvikelwa kwengaphandle lesakhiwo kuhlale isikhathi eside. Ngaphezu kwalokho, i-4,4′ – DIHYDROXYDIPHENYLMETHANE nayo iyavela ezimbonini zokukhiqiza ezisezingeni eliphezulu njengokukhiqiza izimoto kanye nezindiza. Isibonelo, ekuvikelweni kokumbozwa kwezingxenye zezimoto kanye nokuhlanganiswa kwesakhiwo semishini yezindiza, i-4,4′ – DIHYDROXYDIPHENYLMETHANE ibe negalelo ekuthuthukiseni ukusebenza komkhiqizo.

II. Izingozi zempilo ziphakamisa ukukhathazeka. Kodwa-ke, njengoba ucwaningo lujula, izingozi zempilo ezingaba khona ze-4,4′ – DIHYDROXYDIPHENYLMETHANE seziqalile ukuvusa ukuqaphela kwabantu. Izifundo eziningana zesayensi zibonise ukuthi i-4,4′ – DIHYDROXYDIPHENYLMETHANE ingaba ne-endocrine – ephazamisa izakhiwo ezifana ne-4,4′ – DIHYDROXYDIPHENYLMETHANE (BPA). Iziphazamisi ze-endocrine zingaphazamisa uhlelo lwe-endocrine lomuntu futhi zithinte ukukhishwa okuvamile kanye nemisebenzi yokulawula yama-hormone. Ezinye izivivinyo zezilwane zibonise ukuthi izilwane ezivivinywayo ezivezwe endaweni ye-4,4′ – DIHYDROXYDIPHENYLMETHANE zingase zibe nokukhula okungavamile kohlelo lokuzala, ukungasebenzi kahle kwe-thyroid kanye nezinye izimo. Nakuba okwamanje kungekho bufakazi obuqondile obuqondile kubantu, uma sibheka izinkinga zempilo ezake zabangelwa yi-4,4′ – DIHYDROXYDIPHENYLMETHANE kanye nokufana kwezakhiwo zamakhemikhali ze-4,4′ – DIHYDROXYDIPHENYLMETHANE kanye ne-4,4′ – DIHYDROXYDIPHENYLMETHANE, le ngozi engaba khona ayinakubukelwa phansi.

III. Ukuqapha kanye nezinyathelo zokulwa nakho. Ngenxa yezingozi zempilo ezingaba khona ze-4,4′DIHYDROXYDIPHENYLMETHANE, amanye amazwe nezifunda aseqalile ukuyilawula. Iminyango efanele yakha amazinga aqinile ezemvelo kanye nezindinganiso zokuphepha komkhiqizo ukuze kuncishiswe ukusetshenziswa kwe-4,4′ – DIHYDROXYDIPHENYLMETHANE kweminye imikhiqizo engase isondelene nomzimba womuntu. Ngasohlangothini lwebhizinisi, amanye amabhizinisi amakhemikhali kanye namabhizinisi asebenzisa amakhemikhali aphansi nawo ahlola ngenkuthalo ezinye izindlela esikhundleni se-4,4′ – DIHYDROXYDIPHENYLMETHANE, ikakhulukazi emikhakheni enezidingo zokuphepha eziphakeme kakhulu njengokupakisha ukudla kanye nemikhiqizo yezingane. Abasebenzi be-R & D balwela ukuthola izinto ezintsha ezingahlangabezana nezidingo zokusebenza komkhiqizo ngenkathi beqinisekisa ukuthi zinobungane empilweni yabantu kanye nemvelo. 4,4′ – DIHYDROXYDIPHENYLMETHANE idlala indima ebalulekile ekuthuthukisweni kwezimboni, kodwa izingozi zayo zempilo kumele zithathwe ngokungathi sína. Njengoba ucwaningo lwesayensi luqhubeka lujula kanye nokuthuthuka kancane kancane kwezinyathelo zomthetho, kunethemba lokuthi ngenkathi kubhekwa izinzuzo zalo, umonakalo ongaba khona empilweni yabantu kanye nasemvelweni ungancishiswa.
