Mankhwala a mankhwala omwe amagwiritsidwa ntchito kwambiri m'mitundu yambiri ya mafakitale ndi moyo watsiku ndi tsiku ndikuwonjezera chidwi kuchokera pagulu komanso za anthu asayansi.
I. 4,4 '- Dihydroxydupheneili ndi mapulogalamu osiyanasiyana. Mu gawo la mafakitale, 4,4 '- dihhydroxydune ndi zinthu zopangira zopangira - ma epoxy a epoxy. Makina amtunduwu a epoxy amagwiritsidwa ntchito kwambiri m'magetsi ndi mafakitale amagetsi. Mwachitsanzo, pazopangira ma board osindikizira (PCBS), 4,4 '- Dihdroroxydune - Makina Ogwiritsa Ntchito Abwino Kwambiri M'makampani omanga, zida zokhala ndi 4,4 '- Dihydroxyduphene nawonso amatenga gawo lofunikira. Amagwiritsidwa ntchito kupanga okwera - zopindulitsa ndi zomatira, zomwe zimatha kupereka kulimba kwamphamvu komanso zomata, zimapangitsa kuti nyumbayo ikhale yokhazikika komanso chitetezo chakumapeto - kosatha. Kuphatikiza apo, 4,4 '- Dihydroxydune akuyambanso kukweza - omaliza opanga monga magalimoto opanga ndi Aerospace. Mwachitsanzo, kutetezedwa ndi zigawo zamagalimoto ndi mgwirizano wa zida za Aeroprosce, 4,4 '- dihhydroxydune wathandizira kukonza magwiridwe antchito.
Ii. Ngozi zaumoyo zimadzutsa nkhawa. Komabe, monga kafukufuku wofufuza, zoopsa za moyo wa 4,4 '- Dihydroxydune zayamba kudzutsa chidwi cha anthu. Kafukufuku angapo asayansi awonetsa kuti 4,4 '- Dihydroxydune akhoza kukhala ndi endoclane - kusokoneza katundu wofanana ndi 4,4' - Dihydroxydune (BPA). Omwe amayambitsa Endocrine amatha kusokoneza dongosolo la anthu endoclane ndi kusokoneza chinsinsi cha mahomoni komanso ntchito zowongolera mahomoni. Kuyesera kwa nyama kwinaku kwawonetsa kuti nyama zoyesera za 4,4 '- zida za dihydroxysdiphenylhane zimatha kukhala ndi chitukuko cha njira zosabereka, chithokomiro cha chithokomiro ndi zochitika zina. Ngakhale palibe umboni wotsimikizika mwa anthu, chifukwa cha mavuto azaumoyo omwe amakhudzidwa ndi 4,4 '- dihydroxydune ndi kufananako mu mitundu ya mankhwala a 4,4' - dihydroxydune, chiopsezo chomwe chingawonongeke sichitha kusokonekera.
Iii. Kuyang'anira ndi kusankhana. Poona zoopsa zaumoyo wa4,4dihydroxydune, mayiko ndi madera ena ayamba kuwongolera. Madipatimenti oyenera akupanga miyezo yachitetezo cha zachilengedwe kuti muchepetse kugwiritsa ntchito 4,4 '- Dihydroxyduum mu zinthu zina zomwe zingakhale polumikizana kwambiri ndi thupi la munthu. Pa mbali ya bizinesi, mabizinesi ena am'madzi ndi mabizinesi otsika amasanthula njira zina mpaka 4,4 '- dihhroroxydune, makamaka m'minda yomwe ikuchitika kwambiri monga chakudya cha chakudya ndi zinthu zina. Ogwira ntchito a R & D akuyesetsa kupeza zida zatsopano zomwe zingakwaniritse zofunika kuchita pogwiritsa ntchito kuti ndi ochezeka kwa thanzi la anthu komanso chilengedwe. 4,4 '- Dihydroxydune amatenga gawo lofunikira m'mafakitale, koma zoopsa zake ziyenera kutengedwa mozama. Ndi kuyang'ana mosalekeza kwa kafukufuku wasayansi komanso kusintha pang'onopang'ono kwa owongolera, tikuyembekeza kuti ndikumacheza ndi zabwino zake, zomwe zingathe kuvulaza thanzi la anthu ndipo chilengedwe zitha kuchepetsedwa.
