Cov ntaub ntawv ntseeg tau
Cov tshuaj toxicity tsawg dua li ntawm phenols, thiab nws yog cov tshuaj toxicity tsawg. nas LD50 4200mg/kg. Thaum muaj tshuaj lom, koj yuav hnov qhov ncauj iab, mob taub hau, khaus khaus ntawm daim tawv nqaij, ua pa, thiab pob txha. Cov neeg ua haujlwm yuav tsum hnav cov cuab yeej tiv thaiv, cov cuab yeej tsim khoom yuav tsum raug kaw, thiab qhov chaw ua haujlwm yuav tsum muaj qhov cua zoo.
Nws tau ntim rau hauv cov thawv ntoo, lub nruas hlau lossis cov hnab ntim nrog cov hnab yas, thiab qhov hnyav ntawm txhua lub thoob (lub hnab) yog 25kg lossis 30kg. Nws yuav tsum yog fireproof, waterproof thiab tawg-pov thawj thaum khaws cia thiab thauj. Nws yuav tsum tau muab tso rau hauv qhov chaw qhuav thiab ventilated. Nws yog khaws cia thiab thauj khoom raws li cov kev cai ntawm cov tshuaj.
Kev taw qhia luv luv
Bisphenol A (BPA) yog ib qho organic compound. Bisphenol A yog cov xim tsis muaj xim rau xim daj uas yog soluble hauv cov kuab tshuaj organic xws li ketones thiab esters.
Ib txoj hauv kev rau kev npaj ntawm bisphenol A yog los ntawm cov tshuaj tiv thaiv condensation ntawm phenols thiab aldehydes, feem ntau siv acidic catalysts. Thaum lub sij hawm kev npaj, cov tshuaj tiv thaiv tej yam kev mob thiab kev xaiv ntawm catalyst yuav tsum tau tswj kom tau high-purity bisphenol A cov khoom.
Cov Lus Qhia Txog Kev Nyab Xeeb: Bisphenol A raug suav hais tias yog tshuaj lom thiab muaj feem cuam tshuam rau ib puag ncig. Cov kev tshawb fawb tau pom tias BPA tuaj yeem cuam tshuam rau cov kab mob endocrine thiab xav tias muaj kev cuam tshuam tsis zoo rau kev ua me nyuam, paj hlwb thiab kev tiv thaiv kab mob. Kev kis mus ntev rau BPA tuaj yeem cuam tshuam tsis zoo rau kev loj hlob ntawm cov menyuam mos thiab menyuam yaus.
