Polyethylene Sheet (PE ntawv) tsis muaj formaldehyde thiab yog cov khoom tsis muaj tshuaj lom thiab ib puag ncig zoo. Raws li cov kws tshaj lij kev kawm hauv kev tshawb nrhiav:
Cov Khoom Siv Khoom
Lub ntsiab tivthaiv ntawm PE daim ntawv yog polyethylene, thiab cov molecular heev molecular polymer tsis tas yuav ntxiv ntawm formaldehyde thaum lub sijhawm tsim khoom. Cov kev tshawb fawb pom tseeb Lub xeev: "PE Sheet (Polyethylene Sheet) kuj tsis muaj formaldehyde", thiab Baidu Encyclopedia kuj tau piav qhia nws ua "cov khoom tsis muaj tshuaj lom".
Chaw thov
Nws cov yam ntxwv tsis pub muaj iceicaldehyde ua rau nws dav siv hauv cov khoom noj ntim khoom, cov khoom siv kho mob (cov thawv siv tshuaj) thiab lwm daim teb nrog kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv.
Piv nrog lwm cov ntaub ntawv
PVC cov ntawv sau: qee cov phab ntawv PVC yuav muaj formaldehyde vim muaj ntxiv rau cov phab ntsa Yas), tab sis cov ntawv luam tawm yas
PP daim ntawv: Zoo ib yam li PE Sheet, nws tseem yog ib puag ncig yas uas tsis muaj formdehyde.
Cov lus pom zoo: Thaum yuav khoom, koj tseem yuav tsum tau them sai sai ntawm ntawv pov thawj ib puag ncig kom tsis txhob muaj lwm yam teeb meem kev phom sij rau cov ntaub ntawv qis dua. Yog tias koj xav paub ntau ntxiv txog kev nyab xeeb ntawm cov khoom lag luam, koj tuaj yeem kawm cov ntawv polypropylylene lossis cov qauv yas ib puag ncig yas ua ke.
