dziwitsani
ntchito
Amagwiritsidwa ntchito popanga zinthu zosiyanasiyana za polima, monga epoxy resin, polycarbonate, polysulfone ndi phenolic unsaturated resin. Amagwiritsidwanso ntchito popanga ma polyvinyl chloride heat stabilizers, mphira antioxidants, fungicides zaulimi, ma antioxidants ndi mapulasitiki opaka utoto ndi inki, ndi zina zambiri.
chitetezo
Zambiri zodalirika
Kawopsedwe ndi wocheperako kuposa phenols, ndipo ndi mankhwala otsika kawopsedwe. makoswe mkamwa LD50 4200mg/kg. Mukakhala poizoni, mudzamva kuwawa mkamwa, mutu, kuyabwa pakhungu, kupuma, ndi cornea. Oyendetsa ayenera kuvala zida zodzitetezera, zida zopangira ziyenera kutsekedwa, ndipo malo ogwirira ntchito azikhala ndi mpweya wabwino.
Imapakidwa m’migolo yamatabwa, ng’oma zachitsulo kapena matumba okhala ndi matumba apulasitiki, ndipo kulemera kwa mbiya iliyonse (thumba) ndi 25kg kapena 30kg. Iyenera kukhala yosapsa ndi moto, yopanda madzi komanso yosaphulika panthawi yosungira ndi kuyendetsa. Iyenera kuyikidwa pamalo owuma ndi mpweya wabwino. Amasungidwa ndi kunyamulidwa molingana ndi zomwe zimaperekedwa ndi mankhwala wamba.
Chiyambi chachidule
Bisphenol A (BPA) ndi organic compound. Bisphenol A ndi cholimba chopanda mtundu mpaka chachikasu chomwe chimasungunuka mu zosungunulira monga ma ketoni ndi esters.
Njira yodziwika bwino yopangira bisphenol A ndi kudzera mu condensation reaction ya phenols ndi aldehydes, makamaka pogwiritsa ntchito zopangira acidic. Panthawi yokonzekera, zomwe zimachitika komanso kusankha chothandizira ziyenera kuyang'aniridwa kuti mupeze mankhwala oyeretsa kwambiri a bisphenol A.
Chidziwitso Chachitetezo: Bisphenol A imatengedwa kuti ndi yapoizoni komanso yowopsa ku chilengedwe. Kafukufuku wasonyeza kuti BPA ikhoza kukhala ndi zotsatira zosokoneza pa dongosolo la endocrine ndipo imaganiziridwa kuti ili ndi zotsatira zoipa pa ubereki, mantha ndi chitetezo cha mthupi. Kukumana ndi BPA kwa nthawi yayitali kumatha kusokoneza chitukuko cha makanda ndi ana.
