4,4 '- DihydroxyDiphenylmethan: Siv siv dav tab sis kev pheej hmoo txaus ntshai tab sis muaj kev txhawj xeeb

Ib qho tshuaj yeeb zoo siv dav hauv ntau lub neej ntawm kev lag luam thiab lub neej txhua hnub yog kev teeb tsa kev saib xyuas los ntawm cov pej xeem thiab zej zog scientific.

I. 4,4 '- DihydroxyDiphenylmetylmethanemuaj ntau cov ntawv thov. Nyob rau hauv cov lag luam teb, 4,4 '- Dihydrophenylmetylmethans yog cov khoom siv tseem ceeb rau kev tsim khoom siab - kev ua tau zoo epoxy resins. Hom no epoxy no yog siv dav hauv cov khoom siv hluav taws xob thiab hluav taws xob siv khoom lag luam. Piv txwv li, hauv kev tsim cov txheej txheem tsim khoom lag luam Circuit Court pawg (PCBS), 4,4 '- Cov khoom siv hluav taws xob epoxy, tuaj yeem ua kom cov haujlwm hluav taws xob hauv cov hluav taws xob ua haujlwm. Hauv kev tsim kho kev tsim kho, cov ntaub ntawv muaj 4,4 '- DihydroxyDiphenylmetylmethan kuj tseem ua lub luag haujlwm tseem ceeb. Lawv tau siv los tsim cov txheej txheem qib - ua tau zoo tshaj plaws - cov nplaum, uas tuaj yeem muab cov qauv tsim ua kom ruaj khov thiab kev tiv thaiv ntawm lub tsev sab nrauv ntev ntev - ntev. Tsis tas li ntawd, 4,4 '- DihydroxyDiphenylmetylmethans kuj tseem tab tom muaj kev lag luam siab - xaus kev tsim khoom lag luam xws li tsheb tsim thiab aerospace. Piv txwv li, nyob rau hauv cov txheej txheem tiv thaiv ntawm cov khoom siv tsheb thiab cov cuab yeej ua ke ntawm Aerospace khoom, 4,4 '- Dihydriphenylmethylmethane tau pab txhawb rau kev txhim kho ntawm cov khoom lag luam.

Ii. Cov kev pheej hmoo mob nce kev txhawj xeeb. Txawm li cas los xij, raws li kev tshawb fawb tob zuj zus, cov peev xwm muaj txiaj ntsig zoo ntawm 4,4 '- DihydrePriphenylmetylmethanetyane tau pib ua rau cov neeg ceev faj. Muaj ntau cov kev tshawb fawb tau qhia tias 4,4 '- Dihydriphenylmethans yuav muaj ib qho zoo ib yam li 4,4' - Dihydriphenylmetylmethan (BPA). Kev cuam tshuam endocrine tuaj yeem cuam tshuam nrog tib neeg cov kab ke endocrine thiab cuam tshuam qhov tsis sib xws thiab tswj cov haujlwm ntawm cov tshuaj hormones. Qee qhov kev sim tsiaj tau qhia tias cov tsiaj uas muaj sim no raug rau 50,4 '- Dihydrediphenliphenylfuction system, lub qog ua ke thiab lwm yam tshwm sim. Txawm hais tias tam sim no tsis muaj pov thawj ncaj ncees hauv tib neeg, hauv kev pom ntawm kev txhawj xeeb ib zaug ntawm 4,4 '- DihydrMetylmethanethanethanethanetyane, qhov kev pheej hmoo no tsis tuaj yeem xav tsis thoob.

III. Saib xyuas thiab countermeasures. Hauv kev pom ntawm kev muaj peev xwm muaj kev noj qab haus huv ntawm4,4'dihydriphenylmethylmethans, qee lub tebchaws thiab cheeb tsam tau pib tswj nws. Cov chaw haujlwm uas muaj feem xyuam yog tsim cov qauv kev nyab xeeb ntau ib puag ncig thiab cov qauv kev nyab xeeb kom txwv tsis pub siv 4,4 '- Dihydrodiphenylmetylmethanety hauv qee cov khoom uas yuav nyob ze rau tib neeg lub cev. Nyob rau sab enterprise, qee qhov kev lag luam tshuaj lom neeg thiab cov chaw tsim khoom siv tsis zoo rau cov khoom noj thiab cov khoom lag luam me me. R & D cov neeg ua haujlwm yog ua rau pom cov khoom lag luam tshiab uas tuaj yeem ua tau cov khoom lag luam tshiab uas lawv ua phooj ywg rau tib neeg kev noj qab haus huv thiab ib puag ncig. 4,4 '- DihydroxyDiphenylmetylmethanety ua lub luag haujlwm tseem ceeb hauv kev tsim kev tsim kho, tab sis nws yuav tsum tau ua mob hnyav. Nrog kev txuas ntxiv mus tob tob txog kev tshawb fawb thiab kev txhim kho maj mam ua rau muaj kev sib raug zoo, nws cia siab rau tib neeg kev noj qab haus huv thiab ib puag ncig tuaj yeem txo qis.
