Cov ntaub qhwv tsis tuaj yeem ua rau poob?

Seb cov ntaub qhwv puas tuaj yeem cuam tshuam yog nyob ntawm seb cov ntaub ntawv raw siv los ua cov ntaub nonwoven tsis muaj peev xwm.

Raws li hom khoom siv raw, ib txwm tsis yog pp (polypropylene), tus tsiaj (polyester), thiab sib tov ntawm paj rwb thiab polyester. Cov no yog txhua yam tsis-biodegradable thiab tsis tiv taus kev laus. Kev laus hais txog ntawm no yog qhov tshwm sim ntawm kev ua tsis raws kev qias. Nyob rau hauv ib txwm xwm, cua, hnub, thiab los nag yuav ua rau kev ua kom muaj kev cuam tshuam. Piv txwv li, Kuv tau sim pp newwoven ntaub nyob rau hauv nruab nrab cheeb tsam, thiab lawv yeej puas tau tom qab ib xyoos thiab tawg tom qab ib nrab xyoo. Txawm li cas los xij, yog tias lawv tau tso sab hauv tsev, lawv tuaj yeem kav ntev li ntau xyoo, tshwj xeeb tshaj yog thaum muaj av. Cov kws tshawb fawb kwv yees tias nws yuav siv sijhawm li 300 xyoo rau lawv kom tiav degrade.

Puas muaj biOnergradable nonwoven npuag? Cov lus teb yog muaj. Cov ntaub ntawv tsis tau ua los ntawm biodegradable cov ntaub ntawv ib txwm muaj, xws li pla-boosed biodate cov ntaub ntawv lossis petrochemical-based biodegradable, yog tias lawv tsim rau hauv nonwoven Cov ntaub, biodegradable lossis compostable degradation tuaj yeem ua tiav.

Yog tias cov khoom lag luam tsim yog biodegradable thiab compstable, nws yuav tsum tau ua kom tau raws li lub xeev anaeregradation nyob rau hauv cov ntaub ntawv sib tw, tom qab siv tsawg 90% ntawm biodegradation tus nqi hauv cov khoom siv. Lub voj voog no yuav tsum tsis pub tshaj 6 lub hlis. Tsis tas li ntawd, cov nplooj lwg kawg yuav tsum tau ntsib cov qauv av. Tuam Tshoj tus qauv hauv tebchaws GB / t 16716.7 thiab GB / T 28206 tseem muaj cov uas zoo sib xws.

Qhov teeb meem ntxiv yog qhov nyuaj nyuaj ntawm kev tsim cov khoom siv tsis yog los ntawm cov ntaub ntawv. Qhov tseeb, vim tias cov ntaub ntawv no muaj qhov sib txawv loj hauv cov khoom siv tshuab, yog li nws yog ib qho tsim nyog los hloov cov khoom siv raw thiab ntxiv cov khoom siv tsim nyog. Cov khoom siv no tseem tuaj yeem txuas ntxiv ua txuas ntxiv ua cov khoom siv biodegradable. Tam sim no, qee qhov kev ua tiav tau ua, xws li kev tsim cov PLA cov ntsej muag tsis yog, uas tuaj yeem siv cov khaub ncaws ntsej muag, cov khaub ncaws tiv thaiv, thiab pawm.

Nrog rau kev siv ntawm txoj cai, nws tsis yog tiag los ua kom tiav kev siv yas, uas embodies lub teb chaws thiab txawm tias lub ntiaj teb kev txhawj xeeb rau ib puag ncig. Muaj ob txoj hauv kev ua tiav qhov no, ib qho yog kom txo tau cov yas thiab siv cov khoom siv yas, tab sis tam sim no tuaj yeem ua tau zoo txaus, lossis siv ntau dua kev rov ua dua tshiab. Lwm tus yog nce rau kev siv cov khoom siv degradable rau cov khoom siv, xws li cov hnab yas, cov khoom siv yas, cov pawm, thiab lwm yam.

Kev Txhawb Nqa Cov Khoom Tshiab thiab Tshiab Technologies tsis yog kev vam meej hmo ua tiav, thiab nws yuav tsum tau ua txoj kev sib koom tes ntawm cov kws tshaj lij kev ua tiav.
