PLA Spunbond - tus phooj ywg ntawm tib neeg

Polylactic acid (PLA) yog cov khoom siv biodegradable thiab rov ua dua tshiab, uas yog tsim los ntawm cov khoom siv hmoov txhuv nplej siab los ntawm cov khoom siv cog qoob loo (xws li pob kws thiab cassava).Cov khoom siv hmoov txhuv nplej siab tau saccharized kom tau cov piam thaj, thiab tom qab ntawd cov purity lactic acid tau tsim los ntawm fermentation ntawm cov piam thaj thiab qee hom, thiab tom qab ntawd POlylactic acid nrog qee qhov hnyav molecular tau tsim los ntawm cov tshuaj synthesis.Nws muaj biodegradability zoo.Tom qab siv, nws tuaj yeem degraded los ntawm cov kab mob hauv cov kab mob hauv cov xwm txheej tshwj xeeb, thiab thaum kawg tsim cov pa roj carbon dioxide thiab dej.Nws tsis ua phem rau ib puag ncig, uas yog qhov zoo heev rau kev tiv thaiv ib puag ncig thiab raug lees paub tias yog ib puag ncig tus phooj ywg khoom.Tuam Tshoj PP Nonwoven Npuag Nqe

PLA,kuj zoo ib yam li ib yamPET spunbond,Nws muaj cov drapability zoo, smoothness, nqus dej noo thiab huab cua permeability, ntuj bacteriostasis thiab daim tawv nqaij reassuring qaug zog acid, zoo tshav kub tsis kam thiab UV tsis kam.

PLA tag nrho sau ua: polylactic acid

Polylactic acid, tseem hu ua polylactide, belongs rau tsev neeg polyester.Polylactic acid (PLA) yog ib qho polymer uas tau los ntawm polymerization ntawm lactic acid ua cov khoom tseem ceeb.Cov khoom siv raw yog qhov txaus thiab tuaj yeem rov ua dua.Nws tsuas yog siv pob kws thiab cassava ua raw khoom.Cov txheej txheem tsim khoom ntawm PLA tsis muaj kuab paug, thiab cov khoom tuaj yeem raug biodegraded kom paub txog lub voj voog hauv qhov xwm txheej, yog li nws yog cov khoom siv ntsuab zoo tagnrho.

Polylactic acid muaj qhov zoo thermal stability, ua haujlwm kub 170 ~ 230 ℃, hnyav hnyav, tuaj yeem ua tiav ntau txoj hauv kev, xws li extrusion, spinning, biaxial stretching, txhaj tshuaj molding.Cov khoom ua los ntawm polylactic acid tsis yog tsuas yog biodegradable, tab sis kuj muaj biocompatibility zoo, gloss, pob tshab, xav thiab kub tsis kam.Lawv kuj muaj qee yam kab mob ua haujlwm, nplaim hluav taws thiab UV tsis kam, yog li lawv tau siv dav hauv cov khoom ntim, fibers thiab nonwovens, thiab lwm yam. Tam sim no, nws yog siv hauv cov khaub ncaws (cov ris tsho hauv qab, sab nrauv), kev lag luam (kev tsim kho, kev ua liaj ua teb, hav zoov. , ntawv ua) thiab kev kho mob thiab kev noj qab haus huv teb.
