Puas yog PE Yas Zoo rau Khoom Noj?

Polyethylene (PE) yas, cov khoom siv feem ntau siv rau kev ntim khoom noj, tau txais kev saib xyuas rau nws ntau yam thiab kev nyab xeeb. PE yas yog ib lub polymer uas muaj cov ethylene units, paub txog nws stability thiab tsis-reactivity. Cov khoom no ua rau PE yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov zaub mov, vim nws tsis tso cov tshuaj phem rau hauv cov zaub mov, txawm tias raug kub sib txawv.

Kev Tshawb Fawb Txog Kev Nyab Xeeb thiab Kev Cai

Kev tshawb fawb dav dav thiab cov kev cai nruj kom ntseeg tau tias cov khoom noj khoom haus qib PE yas muaj kev nyab xeeb rau kev sib cuag zaub mov. Cov kev tshawb fawb tau pom tias PE yas tsis tso tawm cov khoom tsis zoo raws li kev siv ib txwm siv. Cov koom haum tswj hwm zoo li US Food and Drug Administration (FDA) thiab European Food Safety Authority (EFSA) tau tsim cov txheej txheem thiab cov qauv uas PE yas yuav tsum ua kom tau raws li cov khoom noj-qib. Cov qauv no suav nrog kev sim tshuaj lom neeg tsiv teb tsaws chaw, kom ntseeg tau tias kev hloov pauv ntawm cov tshuaj los ntawm cov yas mus rau cov zaub mov tseem nyob hauv qhov txwv tsis pub muaj kev nyab xeeb.

Kev siv ntau hauv kev ntim khoom noj

PE yas yog siv dav hauv ntau hom ntawv ntim khoom noj, suav nrogPE hnab, hnab zipper, thiabziplock hnab. Cov kev daws teeb meem no muab cov dej noo zoo heev, ua kom yooj yim, thiab ua haujlwm ntev, ua rau lawv tsim nyog rau khaws cia ntau yam khoom noj. PE hnab, piv txwv li, feem ntau yog siv rau cov khoom tshiab, khoom noj txom ncauj, thiab cov khoom noj khov vim lawv muaj peev xwm khaws cia tshiab thiab ua kom lub neej ntev.

Kev sib piv nrog lwm cov yas

Piv nrog rau lwm cov yas, xws li polyvinyl chloride (PVC) thiab polystyrene (PS), PE yas yog suav tias yog kev nyab xeeb thiab zoo ib puag ncig. PVC, piv txwv li, tuaj yeem tso cov tshuaj phem xws li phthalates thiab dioxins, tshwj xeeb tshaj yog thaum cua sov. Hauv qhov sib piv, PE yas cov qauv tshuaj lom neeg yooj yim thiab kev ruaj ntseg ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev ntim khoom noj, vim nws ua rau muaj kev phom sij tsawg.

Txhawb Cov Ntaub Ntawv thiab Kev Tshawb Fawb

Cov ntaub ntawv los ntawm kev tshawb fawb kev lag luam txhawb kev ruaj ntseg ntawm PE yas. Piv txwv li, ib txoj kev tshawb fawb los ntawm EFSA tau pom tias kev tsiv teb tsaws ntawm cov khoom ntawm PE yas rau hauv cov zaub mov tau zoo nyob rau hauv cov kev txwv kev nyab xeeb. Tsis tas li ntawd, lub siab rov ua dua tshiab ntawm PE yas ntxiv txhim kho nws qhov kev thov, vim nws tuaj yeem ua tiav rau hauv cov khoom tshiab, txo kev cuam tshuam ib puag ncig.

Hauv kev xaus,PE hnab, hnab zipper, thiabziplock hnabua los ntawm cov khoom noj-qib PE yas muaj kev nyab xeeb thiab txhim khu kev qha rau kev ntim khoom noj. Lawv cov tshuaj lom neeg ruaj khov, ua raws li cov qauv kev nyab xeeb, thiab kev siv dav hauv kev lag luam ua rau lawv muaj kev xaiv zoo rau cov neeg siv khoom nrhiav khaws thiab tiv thaiv lawv cov zaub mov.
