PLA Spunbond- umhlobo womntu

I-Polylactic acid (PLA) yimathiriyeli entsha esekwe kwibhayoloji nehlaziyekayo, eyenziwe ngemathiriyeli yesitatshi ecetywa ngemithombo yezityalo ehlaziyekayo (efana nombona kunye necassava).Isitashi izinto ekrwada zaye saccharized ukufumana iswekile, kwaye ke ubunyulu obuphezulu lactic acid lwenziwa ukubilisa iswekile kunye neentlobo ezithile, kwaye ke acid POLylactic kunye ubunzima ethile molekyuli yadityaniswa synthesis imichiza.Inokonakala kwezinto eziphilayo.Emva kokusetyenziswa, inokutshatyalaliswa ngokupheleleyo ngama-microorganisms kwindalo phantsi kweemeko ezithile, kwaye ekugqibeleni ivelise i-carbon dioxide kunye namanzi.Ayingcolisi imo engqongileyo, nto leyo eluncedo kakhulu ekukhuselweni kwendalo kwaye yamkelwa njengezinto ezinobungani nokusingqongileyo.China PP Nonwoven Fabric Price

I-PLA,iyafana nolunye uhloboI-PET spunbond,inokutsaleka okugqwesileyo, ukuguda, ukufunxa ukufuma kunye nokungena komoya, i-bacteriostasis yendalo kunye nolusu oluqinisekisa iasidi ebuthathaka, ukumelana nobushushu obulungileyo kunye nokuxhathisa kwe-UV.

I-PLA yonke ibhalwe njenge:i-polylactic acid

I-Polylactic acid, eyaziwa ngokuba yi-polylactide, yeyosapho lwe-polyester.I-Polylactic acid (PLA) i-polymer efunyenwe nge-polymerization ye-lactic acid njengeyona nto iphambili ekrwada.Umthombo wemathiriyeli ekrwada wanele kwaye unokuphinda usetyenziswe.Ikakhulu isebenzisa umbona kunye necassava njengemathiriyeli ekrwada.Inkqubo yemveliso ye-PLA ayingcolisekanga, kwaye imveliso inokuguqulwa ibe yi-biodegraded ukuze iqonde umjikelo kwindalo, ngoko ke yinto efanelekileyo yepolymer eluhlaza.

Iasidi yePolylactic inozinzo oluhle lwe-thermal, ubushushu bokusebenza 170 ~ 230 ℃, ukuxhathisa okulungileyo kwe-solvent, inokucutshungulwa ngeendlela ezahlukeneyo, ezifana ne-extrusion, i-spinning, i-biaxial stretching, i-injection blow blowing.Iimveliso ezenziwe nge-polylactic acid azigcini nje ukubola, kodwa zine-biocompatibility efanelekileyo, i-gloss, i-transparency, imvakalelo kunye nokumelana nokushisa.Kwakhona banayo ukumelana ethile ibhaktheriya, idangatye retardant kunye UV nokumelana, ngoko ke zisetyenziswa ngokubanzi njengezinto ukupakisha, imicu kunye nonwovens, etc. Okwangoku, isetyenziswa ikakhulu impahla (zangaphantsi, outerwear), ishishini (ukwakha, ezolimo, amahlathi. , ukwenziwa kwephepha) kunye neenkalo zonyango kunye nempilo.
