Lub Cuab Yeej Phem Daim Ntawv Pov Thawj
Cov khob ntawm lub lag luam uas muaj cov khoom sib txawv uas muaj feem ntau dua. Thiaj li yuav ua rau lub khob zoo dua dawb, qee cov ntaub ntawv khob manufacturers ntxiv fluorescent kom nws ci ntsa iab. Cov ntaub ntawv muaj peev xwm ua rau lub hlwb ua kom txawv, ib zaug mus rau hauv tib neeg lub cev yuav ua tau cov kab mob carcinogenic.
Txhawm rau ua kom cov ntawv khob muaj dej ntim tsis muaj dej, qhov tsim tau ntawm polyethylene puab phab ntsa nrog polyethylene zaj duab xis, polyethylene yog cov khoom noj khoom haus zoo tshaj plaws, tab sis yog tias cov khoom tsis zoo los yog kev lis kev cai, polyethylene hauv cov kub yaj yuav carbonyl tebchaw, uas tsis tshua muaj kev kub ntxhov ntawm ambient kub, tab sis cov neeg tsis muaj zog thaum uas muab hliv rau hauv dej kub, kom neeg tsis hnov tsw tsw. Txawm hais tias tsis muaj cov kev tshawb fawb tau pom tias carbonyl tebchaw tso tawm los ntawm cov khob khob yog tsim kev puas tsuaj rau tib neeg quavntsej, qhov ntev ntawm lub cev ntev ntawm cov organic compounds yog tsim rau tib neeg lub cev. Txawm tias muaj ntau txoj kev txhawj xeeb, qee qhov yog siv cov khoom siv polyethylene uas tsis zoo rau cov ntawv khob, uas tuaj yeem ua rau muaj kev hloov hauv kev ntes thaum ua haujlwm, ua rau ntau cov khoom muaj sia mus yoojyim rau hauv dej thaum siv. Lub xeev txwv tsis pub siv cov polyethylene rau cov khoom noj khoom noj khoom haus, tab sis qee qhov chaw me me kom txuag tau cov nqi, tseem yog ua txhaum.
Hauv cov khob ntawm daim ntawv thiaj li ua kom tiav cov dej ua pov thawj, yuav muaj coated nrog polyeth ylene sab hauv phab ntsa rwb thaiv tsev. Polyethylene yog ib qho kev ruaj ntseg hauv cov zaub mov. Insoluble nyob rau hauv dej, uas tsis yog-tshuaj lom thiab tasteless. Lub hauv paus compound tsis volatilize nyob rau hauv chav tsev kub, tab sis thaum lub khob khob yog poured rau hauv dej kub, nws evaporates thiab smelt nws. Ntev kom ntev ntawm cov organic no, tsis conducive rau kev kho mob, los sis tseem mob cancer.
Nyob hauv lub teb chaws ntawv ntawm lub khob ntawv zoo, tsuas yog cov kab mob ntawm cov kab mob yuav tsum tau sim, kev kuaj tshuaj ntawm cov tshuaj chemicals tsis tau ua tiav, vim qhov kev kuaj ntawd nyuab heev thiab nyuaj ua kom tiav. Qee cov ntawv khob muaj kev pheej hmoo siab mob cancer vim yog qhov tsis zoo ntawm cov txheej txheem pulping thiab ntau ntau cov tshuaj fluorescent yog ntxiv rau cov khoom hauv daim duab dawb. Nws xav kom tsis txhob siv cov khob dej uas siv tau, xws li cov dej txias zoo tshaj plaws, kom txo tau txoj kev pheej hmoo ntawm tshuaj lom neeg ua phem los ntawm kev ua kom qhuav.
Yog tias koj xav tau kev ua haujlwm zoo, siv lub khob rau kev siv, thov xaiv Pando . Txog rau tam sim no, peb tau dhau los thiab tau ntau yam ntaub ntawv pov thawj los txhawb peb cov ntawv ua lag luam. Cov ntawv pov thawj tau muab rau kev nyab xeeb ntawm kev nyab xeeb, kev ua raws cai rau ib puag ncig, thiab kev tsim khoom. Peb tau cog lus tias yuav tau muab cov ntawv kas fes kom huv, muaj kev ruaj ntseg, thiab muaj ntaub ntawv zoo, cov khob ntawm compostable ntawv rau cov neeg siv khoom.
