Acrylamide's Siv Ua Kev Pabcuam Kev Lag Luam

Cov ntawv tseem ceeb thiab kev ua haujlwm

Hauv cov ntawv thov kev lag luam, tshwj xeeb tshaj yog nyob rau hauv textile dyeing thiab xov, acrylamide feem ntau yog siv nyob rau hauv nws daim ntawv polymerized -polyacrylamide (PAM) los yog co-monomer nyob rau hauv ntau yam copolymer. Nws yog tsis tshua muaj siv raws li ib tug ntshiab monomer nyob rau hauv cov khoom kawg vim toxicity.

Nws lub luag haujlwm tseem ceeb ua tus neeg sawv cev pabcuam suav nrog:

· Dye Fixative: Polyacrylamide-raws li copolymers (tshwj xeeb tshaj yog cov cationic ones) yog dav siv los kho cov neeg sawv cev. Lawv txhim kho kev ntxuav- nrawm thiab ntub dej- nrawm nrawm ntawm cov xim (xws li cov dyes ncaj qha lossis reactive dyes) ntawm cov ntaub los ntawm kev tsim cov yeeb yaj kiab thiab sib txuas nrog cov xim molecules.

· Tus neeg saib xyuas qib: Qee cov PAM derivatives tuaj yeem tswj cov dyeing tus nqi, pab dyes nqus tau ntau dua rau cov fibers kom tsis txhob muaj xim xim.

· Fiber Modifier: Acrylamide monomer tuaj yeem raug grafted rau hauv cov fibers ntuj (xws li paj rwb) los qhia cov tshuaj tshiab. Qhov kev hloov kho no tuaj yeem txhim kho cov fiber ntau affinity rau dyes lossis tsim cov khoom tshwj xeeb.

· Thickener thiab Binder: Hauv textile printing, PAM yog siv los ua ib feem ntawm paste thickeners los yog binders kom paub meej cov qauv thiab zoo adhesion ntawm pigments rau ntaub.

· Antistatic thiab Softening Agent: Siv rau hauv cov ntaub tom qab -kev kho mob los txhim kho txhais tes thiab kev ua haujlwm.

Kev Nyab Xeeb Tseem Ceeb thiab Cov Lus Ceeb Toom

Qhov kev nyab xeeb yog qhov tseem ceeb tshaj plaws thaum tham txog acrylamide ua cov tshuaj siv tshuaj.

· Monomer Toxicity: Acrylamide monomer yog ib qho neurotoxin thiab xav tias tib neeg carcinogen (tseem hu ua IARC Group 2A). Nws tuaj yeem nqus tau los ntawm daim tawv nqaij.

· Kev txwv tsis pub nyob hauv cov khoom lag luam: Vim qhov kev phom sij no, cov qauv kev lag luam thoob ntiaj teb tseem ceeb rau textiles (xws li OEKO-TEX® Standard 100) nruj me ntsis txwv cov dawb acrylamide monomer tso cai kom nyob twj ywm hauv cov neeg siv khoom tiav. Qhov txwv tsis pub muaj tsawg heev, feem ntau nyob ib ncig ntawm 0.1 mg / kg.

· Kev Lag Luam Kev Lag Luam: Hauv kev tsim khoom, tuav acrylamide monomer yuav tsum muaj kev tswj hwm engineering nruj thiab cov cuab yeej tiv thaiv tus kheej (PPE) los tiv thaiv cov neeg ua haujlwm raug.

Txhawm rau muab nws yooj yim: Hauv kev lag luam, acrylamide tus nqi nyob hauv nws daim ntawv polymer, polyacrylamide, uas yog ntau yam kev pabcuam. Txawm li cas los xij, nws txoj kev siv yog tswj hwm nruj heev vim muaj cov tshuaj toxicity siab ntawm nws daim ntawv monomer unreacted.
