I-4,4 '- I-Dihydroxydiphmenylenylenylemenenenesenenethethenesenenethane: Kusetshenziswa kabanzi kepha izingozi zempilo zikhathazekile

Into yamakhemikhali esetshenziswa kabanzi emikhakheni eminingi yezimboni kanye nempilo yansuku zonke idonsela ukunaka okwandayo okuvela emphakathini kanye nomphakathi wesayensi.

I. 4,4 '- I-Dihydroxydiphenenylmenenyllenyllemenenenethaneinezinhlobonhlobo zezicelo. Ensimini yezimboni, abangu-4,4 '- I-Dihydroxydiphmenylmenenylenylmenenenethenethethenethetheneta iyisici esibalulekile sokukhiqiza okuphezulu - ama-epoxy aphezulu. Lolu hlobo lwe-epoxy resin lusetshenziswa kabanzi kwizimboni ze-elekthronikhi nasekusebenzeni kagesi. Isibonelo, enqubweni yokukhiqiza yamabhodi wesifunda aphrintiwe (ama-PCB), 4,4 '- I-Dihydroxydiphmenylmenenylmenenenenethane - thayipha ama-epoxy resins, anokushisa okuqinile, angaqinisekisa ukusebenza kwezinto ezizinzile, kungaqinisekisa ukusebenza kwezinto ezizinzile ezindaweni eziyinkimbinkimbi ezisebenzayo. Embonini yezokwakha, izinto zokwakha eziqukethe ama-4,4 '- I-Dihydroxydiphenylemenylemenemenenenenenenenenenenese futhi badlala indima ebalulekile. Zisetshenziselwa ukukhiqiza okuphezulu - ukumbona ukusebenza kanye nama-adhesives, anganikeza ukuqina okuhle nokunamathela, okwenza isakhiwo sokwakha sizinzile nokuvikelwa kwesakhiwo ngaphandle okude. Ngaphezu kwalokho, i-4,4 '- I-Dihydroxydiphmenylmenenenenenenenenethane iyavela nasezimbonini zokukhiqiza eziphezulu ezinjengokukhiqiza izimoto kanye ne-aerospace. Isibonelo, ekuvikelweni kwenhlanganisela kwezimoto ezihamba ngezimoto kanye nokuhlanganiswa kwesakhiwo zemishini ye-aerospace, 4,4 '- I-Dihydroxydiphmenylmenenenenenenenenethane ifake isandla ekuthuthukisweni kokusebenza komkhiqizo.

II. Ubungozi bezempilo buphakamisa ukukhathazeka. Kodwa-ke, njengoba ucwaningo luyajula, izingozi ezingaba khona zezempilo ezingama-4,4 '- UDihydroxydiphenylemenemenenenenenenenenese bavukele ukuvusa amandla abantu. Ucwaningo oluningi lwesayensi lukhombisile ukuthi i-4,4 '- I-Dihydroxydiphhenylnenylenylnenenenenenenenenenenene kungenzeka i-endocrine - ukuphazamisa izakhiwo ezifana ne-4,4' - Dihydroxydiphenmenylemenylemenylenylemenenylemenylenylemenenylemenenylemenenylemenenylenenenmenylemenylemenenylenenenmenylemenenylemenenenmenylemenylemenenenmenylemenenenmenylemenenenmenylemenenenmenylemenenylenenenmenylemenenylemenenylenenenmenylemenenenmenylemenenylenenenmenylemenenenmenylemenenenmenylemenenylemenenylenenenmenylemenenylemenenylemenenylemenenenmenylemenenenmenylemenenenmenylemenenenenenenenenene (BPA). Abaphazamisi be-Endocrine bangaphazamisa uhlelo lwe-endocrine yabantu futhi bathinte imfihlo ejwayelekile kanye nemisebenzi yokulawula ama-hormone. Ezinye izivivinyo zezilwane zikhombisile ukuthi izilwane ezivivinyayo ezivezwa i-4,4 '- I-Dihydroxydiphenylmenenylmenenenylmeneneneneneneneve kungenzeka ithuthukiswe ngohlelo lokuzala, ukudonsa kwe-thyroid nezinye izinto. Yize kungabikho bobufakazi obuqondile njengamanje kubantu, ngokubheka ukukhathazeka kwezempilo okubangelwa yi-4,4 '- I-Dihydroxydiphenylemenenenylenyllemenemenemenemenemenemenemenemenemenenenenenenenenenenethenenenenethenenenethenenethane, le ngozi engahle ingenakubukelwa phansi.

III. Ukwengamela kanye nokukhubazeka. Ngenxa yobungozi bezempilo obukhona be-4,4'dihydroxydiphenylmenenenenenenenenenethane, amanye amazwe nezifunda sebeqalile ukuyilawula. Iminyango efanelekile yenziwa amazinga aqinile emvelo namazinga okuphepha womkhiqizo ukunciphisa ukusetshenziswa kwe-4,4 '- I-Dihydroxydiphenylmenenenenenenenenenenethane kweminye imikhiqizo yabantu. Ngasohlangothini lwamabhizinisi, amanye amabhizinisi amakhemikhali namabhizinisi aphansi azohlola ngenkuthalo ngezindlela ezi-4,4 '- I-Dihydroxydiphenylmenenenenethenenethenesenenenethenethenenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethenethethane kakhulu izidingo zokuphepha kanye nemikhiqizo yezingane. Abasebenzi be-R & D balwela ukuthola izinto ezintsha ezingahlangabezana nezidingo zokusebenza komkhiqizo ngenkathi ziqinisekisa ukuthi zinobungane empilweni yabantu nasendaweni yemvelo. I-4,4 '- I-Dihydroxydiphhenylemenemenenenethane idlala indima ebalulekile ekuthuthukisweni kwezimboni, kepha izingozi zayo zempilo kufanele zithathwe ngokungathi sína. Ngokujula okuqhubekayo kocwaningo lwesayensi nokuthuthuka kancane kwezinyathelo zokulawula, kuthenjwa ukuthi ngenkathi kunikeza ukudlala izinzuzo zako, ukulimala okungaba yingozi empilweni yabantu futhi imvelo ingancishiswa.
