Uas yog zoo dua, tag nrho degradable noj su lub thawv los yog tsoos polyethylene tableware
Kev nce siab ntawm cov thawv ntim khoom noj uas tsis muaj pov tseg tau nrawm dua li ntau tus neeg xav txog, thiab nws cov txiaj ntsig ib puag ncig thiab cov txiaj ntsig kev sib raug zoo yog qhov zoo dua li cov khoom noj khoom haus polyethylene. Cov ntaub ntawv hauv Is Taws Nem hais txog qhov twg ib qho ntawm cov khoom noj khoom haus uas tsis muaj kev puas tsuaj tag nrho muaj lub koob npe zoo yog lub npe nrov hauv kev lag luam catering. Tam sim no kuv yuav piav qhia luv luv txog qhov twg yog qhov zoo dua, lub thawv ntim khoom noj uas tsis muaj pov tseg thiab cov tsoos polyethylene tableware:
1. Lub thawv ntim khoom noj uas muaj peev xwm degradable tag nrho muaj cov khoom muaj zog decomposition muaj peev xwm
Lub luag haujlwm tseem ceeb ntawm lub thawv ntim khoom noj uas tsis muaj degradable yog tshem tawm thiab xa tawm, thiab nws cov khoom muaj peev xwm decomposition muaj zog dua li cov tsoos polyethylene tableware. Vim hais tias cov tshuaj polyethylene tableware yog ua los ntawm polyethylene, polypropylene thiab melamine li raw cov ntaub ntawv, txawm hais tias nws muaj zog kub kuj thiab bearing peev xwm, nws tsis yooj yim rau decompose thiab yooj yim ua paug ib puag ncig.
2. Lub sij hawm degradation ntawm tag nrho cov degradable noj su lub thawv yog luv
Raws li cov lus tawm tswv yim los ntawm cov kws tshaj lij, lub thawv ntim khoom noj uas tsis muaj pov tseg tag nrho muaj lub sijhawm degradation luv dua li cov tsoos polyethylene tableware. Vim hais tias cov tsoos polyethylene tableware yog ua los ntawm polyethylene compound, qhov txo qis ntawm cov khoom siv polyethylene no qeeb qeeb dua li ntawm lub thawv noj su, yog li kev hais lus, qhov degradation tshwm sim los ntawm tag nrho cov degradable noj su lub thawv yog qeeb dua. Ib puag ncig muaj kuab paug tsawg dua.
3. Kev ntsuam xyuas toxicological ntawm lub thawv ntim khoom noj uas muaj peev xwm degradable yog ntau txhim khu kev qha
Feem ntau ntawm cov khoom noj khoom haus uas tau muab pov tseg tag nrho tau ua tiav qhov kev kuaj toxicology ua ntej tawm hauv lub hoobkas. Cov tsoos polyethylene tableware nws tus kheej muaj qee qhov kev faib ua feem ntawm cov tshuaj, yog li yog tias qee cov polyethylene tableware yog tsim los ntawm lub Hoobkas ua haujlwm me me, nws yuav muaj qee qhov toxicity seem, thiab kev kuaj toxicology ntawm cov khoom noj khoom haus degradable tag nrho yog hnyav heev.
Lub thawv ntim khoom noj uas tsis muaj pov tseg tag nrho yog tsim los ntawm qhov nrawm, thiab cov lus "Qhov twg tuaj yeem tso siab rau lub thawv noj su tag nrho" tau sau txhua qhov chaw hauv Is Taws Nem. Piv nrog cov khoom noj khoom haus polyethylene ib txwm muaj, nws muaj qhov zoo dua, vim tias lub thawv ntim khoom noj khoom haus uas tsis muaj degradable tag nrho muaj cov khoom muaj zog decomposition muaj peev xwm thiab lub sij hawm luv luv degradation, thiab nws cov toxicological xeem yog ntau txhim khu kev qha.
