Dab tsi yog qhov phom sij ntawm acrylates?
Acrylates yog ib pawg ntawm cov tshuaj siv dav hauv ntau qhov kev lag luam, suav nrog kev tsim khoom, kev tsim kho, thiab kev kho mob. Thaum lawv muab ntau yam txiaj ntsig, xws li lub sijhawm kho sai thiab cov khoom nplaum, lawv kuj ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv thiab ib puag ncig. Tsab ntawv xov xwm no yog tsom rau tshawb nrhiav cov kev pheej hmoo cuam tshuam nrog acrylates, suav nrog lawv cov tshuaj lom neeg, muaj peev xwm ua rau tawv nqaij rhiab heev, thiab kev cuam tshuam ib puag ncig.
Toxic teebmeem ntawm acrylates
Acrylates tau pom tias muaj tshuaj lom rau tib neeg, tshwj xeeb tshaj yog thaum kis tau tshwm sim los ntawm kev nqus, sib cuag ntawm daim tawv nqaij, lossis kev noj. Qhov hnyav ntawm cov teebmeem no nyob ntawm ntau yam, xws li hom tshwj xeeb ntawm acrylate, concentration, thiab lub sijhawm raug.
Ib qho ntawm cov tshuaj lom ntau tshaj plaws ntawm acrylates yog khaus rau ntawm daim tawv nqaij, qhov muag, thiab ua pa. Ntev ntev los yog rov ua dua tuaj yeem ua rau mob dermatitis, uas muaj qhov liab, khaus, thiab o ntawm daim tawv nqaij. Hauv cov xwm txheej hnyav, nws tuaj yeem ua rau hlwv thiab tev. Qhov muag khaus tuaj yeem tshwm sim liab, kua muag, thiab kub hnyiab. Kev nqus pa ntawm acrylate vapors lossis hmoov av tuaj yeem ua rau ua pa ua pa, ua rau hnoos, ua pa luv, thiab hauv siab nruj.
Ntev mus ntev rau qee yam acrylates kuj tau txuas rau kev noj qab haus huv hnyav dua. Piv txwv li, qee qhov kev tshawb fawb tau pom tias methyl methacrylate, ib qho siv acrylate feem ntau hauv kev tsim cov yas thiab cov ntaub ntawv kho hniav, tej zaum yuav yog carcinogenic. Ib yam li ntawd, raug rau ethyl acrylate tau cuam tshuam nrog kev yug me nyuam thiab kev loj hlob toxicity.
Daim tawv nqaij rhiab heev muaj peev xwm
Acrylates paub tias muaj peev xwm ua rau rhiab heev, txhais tau tias lawv tuaj yeem ua rau muaj kev fab tshuaj rau cov tib neeg uas tau raug mob yav dhau los. Sensitization yog ib qho kev tsis haum tshuaj uas tshwm sim tom qab rov raug ib yam tshuaj. Nws txawv ntawm qhov khaus khaus, uas yog qhov tsis ua xua. Kev hnov mob rau acrylates tuaj yeem ua rau muaj kev fab tshuaj tiv thaiv kab mob dermatitis, ib qho mob ntawm daim tawv nqaij uas tshwm sim los ntawm liab, khaus, thiab pob khaus.
Qee cov acrylates, xws li methacrylates, feem ntau yuav ua rau rhiab heev piv rau lwm tus. Cov tib neeg uas ua haujlwm hauv kev lag luam uas feem ntau siv acrylates, xws li kev kho hniav, luam ntawv, lossis cov khw muag ntsia thawv, muaj kev pheej hmoo siab dua ntawm kev tsim kev puas tsuaj. Nws yog ib qho tseem ceeb rau cov tib neeg no yuav tsum tau ua raws li kev tiv thaiv kom tsim nyog, xws li hnav hnab looj tes tiv thaiv thiab siv qhov cua kom txaus, kom txo tau qhov kev pheej hmoo ntawm kev hnov mob.
Kev cuam tshuam ib puag ncig
Sib nrug los ntawm lawv cov kev cuam tshuam rau tib neeg kev noj qab haus huv, acrylates kuj tuaj yeem cuam tshuam rau ib puag ncig. Kev tsim thiab pov tseg ntawm acrylates tuaj yeem ua rau huab cua, dej, thiab av paug.
Thaum lub sij hawm tsim cov acrylates, volatile organic tebchaw (VOCs) feem ntau tso rau hauv qhov chaw. Cov VOCs no tuaj yeem hnov mob nrog lwm cov pa phem hauv huab cua thiab pab tsim cov smog. Qee cov acrylates kuj tseem nyob hauv ib puag ncig, txhais tau tias lawv tsis yooj yim tawg thiab tuaj yeem sib sau hauv av thiab dej hauv lub sijhawm. Qhov no tuaj yeem muaj kev cuam tshuam tsis zoo rau ecosystems thiab dej hauv dej.
Tsis tas li ntawd, kev pov tseg tsis raug ntawm cov khoom siv acrylate tuaj yeem ua rau cov kev txhawj xeeb ntawm ib puag ncig ntau ntxiv. Thaum muab pov tseg rau hauv qhov chaw pov tseg, acrylates tuaj yeem nkag mus rau hauv cov dej hauv av, muaj feem cuam tshuam cov dej haus. Incineration ntawm acrylates tuaj yeem tso tawm cov khoom muaj kuab lom rau hauv huab cua, ua rau muaj kuab paug rau huab cua.
Kev tiv thaiv kev ntsuas thiab kev cai
Txhawm rau txo cov kev phom sij cuam tshuam nrog acrylates, ntau yam kev tiv thaiv thiab kev tswj hwm tau siv nyob rau hauv ntau lub teb chaws. Cov kev ntsuas no txhawm rau tiv thaiv cov neeg ua haujlwm thiab cov pej xeem sawv daws los ntawm kev pheej hmoo kev noj qab haus huv.
Kev ntsuas kev nyab xeeb ntawm chaw ua haujlwm
Hauv kev lag luam uas siv cov acrylates, cov tswv lag luam yog lub luag haujlwm rau kev siv cov kev ntsuas kev nyab xeeb kom txo tau cov neeg ua haujlwm raug. Qhov no suav nrog kev muab cov cuab yeej tiv thaiv tus kheej tsim nyog (PPE), xws li hnab looj tes, tsom iav, thiab kev tiv thaiv ua pa. Lub tshuab cua kom txaus yuav tsum nyob rau hauv qhov chaw los tswj thiab tshem tawm cov vapors thiab plua plav. Kev saib xyuas huab cua tsis tu ncua kuj tseem yog qhov tseem ceeb kom ntseeg tau tias cov qib raug nyob hauv qhov kev txwv tau txais.
Cov txheej txheem tswj hwm
Ntau lub tebchaws tau tsim cov txheej txheem tswj hwm los tswj kev siv thiab pov tseg ntawm acrylates. Cov kev cai no feem ntau suav nrog cov lus qhia rau kev tso cai txwv tsis pub muaj kev txwv, kev sau npe yuav tsum tau ua, thiab cov txheej txheem tuav kom nyab xeeb. Piv txwv li, European Union tau txais kev tso npe, kev ntsuam xyuas, kev tso cai, thiab txwv tsis pub siv tshuaj lom neeg (REACH), uas yog lub hom phiaj los ntsuas thiab tswj cov kev pheej hmoo cuam tshuam nrog cov tshuaj chemical, suav nrog acrylates.
Tsis tas li ntawd, ntau lub koom haum thoob ntiaj teb, xws li Lub Chaw Haujlwm Saib Xyuas Kev Tshawb Fawb Thoob Ntiaj Teb rau Cancer (IARC) thiab Lub Koom Haum Saib Xyuas Kev Noj Qab Haus Huv Ntiaj Teb (WHO), tau ua cov kev soj ntsuam ntawm carcinogenicity thiab toxicity ntawm acrylates. Lawv qhov kev tshawb pom tau ua rau muaj kev txhim kho cov lus qhia thiab cov lus pom zoo rau kev coj ua kom nyab xeeb.
Xaus
Thaum acrylates muab ntau cov txiaj ntsig hauv ntau qhov kev lag luam, nws yog ib qho tseem ceeb kom paub txog lawv cov kev phom sij. Cov tshuaj no tuaj yeem ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv, suav nrog daim tawv nqaij thiab ua pa ua pa, nrog rau kev noj qab haus huv ntev dua. Acrylates kuj muaj peev xwm ua rau rhiab heev thiab tuaj yeem ua rau muaj kab mob dermatitis. Tsis tas li ntawd, lawv cov khoom tsim thiab pov tseg tuaj yeem ua rau muaj kuab paug ib puag ncig.
Txhawm rau txo qhov kev pheej hmoo cuam tshuam nrog acrylates, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov kev tiv thaiv tsim nyog hauv chaw ua haujlwm, xws li siv PPE thiab ua kom muaj qhov cua zoo. Kev ua raws li txoj cai tswjfwm thiab cov lus qhia tseem ceeb heev los xyuas kom muaj kev nyab xeeb thiab kev coj ua pov tseg. Thaum kawg, kev nkag siab zoo txog kev phom sij ntawm acrylates tuaj yeem pab tiv thaiv tib neeg kev noj qab haus huv thiab ib puag ncig.
