PLA non-woven npuag yog dab tsi? Puas yog polylactic acid non-woven fabric tib yam li nws?
PLA non-woven npuag yog cov khoom tshiab, degradable, tsis muaj tshuaj lom thiab tsis muaj kuab paug. Cov khoom no yog ua los ntawm ntsuab thiab ib puag ncig tus phooj ywg raw khoom "polylactic acid", yog li nws tseem hu ua "polylactic acid non-woven fabric". Lawv yog cov npe sib txawv rau tib yam khoom. Qhov tseeb, nws kuj muaj lwm lub npe, xws li: "degradable non-woven fabric" thiab "corn fiber non-woven fabric".
PLA tsis-woven npuag siv tau pes tsawg xyoo?
Lub sijhawm siv tau ntawm cov ntaub tsis-woven feem ntau yog ob xyoos. Yog hais tias nws yog siv nyob rau hauv ib tug hnyav ib puag ncig, nws yog feem ntau yog hais txog ib xyoos. Yog tias nws nyob hauv ib puag ncig corrosive, nws feem ntau yog ib nrab xyoo. Nws lub neej kev pabcuam cuam tshuam zoo heev los ntawm kev siv ib puag ncig.
Lub sijhawm degradation ntawm PLA tsis-woven npuag:
Nws lub sijhawm degradation thiab tuag yog li ib nrab xyoo, uas yog, 180 hnub. Thaum lub sij hawm nws cov txheej txheem decomposition, nws tsis ua rau muaj kev puas tsuaj rau ib puag ncig, thiab nws tuaj yeem decompose nyob rau hauv ib puag ncig ntuj yam tsis tas yuav tsum tau kho tshwj xeeb.
Qhov zoo ntawm PLA non-woven fabrics:
Nws muaj kev ua pa zoo heev, tshwj xeeb tshaj yog thaum siv lub qhov ncauj qhov ntswg, tiv thaiv khaub ncaws thiab lwm yam khoom. Nws yuav tsis tsim cov dej vapor ntau vim yog av noo heev, uas yuav cuam tshuam rau kev siv. Nws muaj qhov ntom ntom thiab uniform microporous microporous tus qauv, uas tsis yog tsuas yog ua taus tsis taus xwb, yog li nws tseem siv rau tsev cog khoom. Nws lub zog yog siab txaus thiab tuaj yeem siv rau hauv cov yub los ua cov hnab yub. Lub hnab yub hom no muaj qhov zoo ntawm kev khaws cia noo noo thiab breathability hais saum toj no. Nws plays lub luag haujlwm tseem ceeb hauv kev loj hlob ntawm cov nroj tsuag hauv paus system thiab muaj txiaj ntsig zoo rau cov nroj tsuag kev loj hlob.
