PLA Spunbond- bwenzi la munthu

Polylactic acid (PLA) ndi chinthu chatsopano chochokera ku biodegradable, chomwe chimapangidwa kuchokera ku zinthu zowuma zomwe zimaperekedwa ndi zomera zongowonjezereka (monga chimanga ndi chinangwa).Wowuma zopangira anali saccharized kuti shuga, ndiye mkulu chiyero lactic acid anapangidwa ndi nayonso mphamvu shuga ndi zina zochulukira, ndiyeno POLylactic asidi ndi ena molekyulu kulemera anali apanga ndi synthesis mankhwala.Ili ndi biodegradability yabwino.Mukatha kugwiritsa ntchito, zitha kuwonongeka kwathunthu ndi tizilombo tating'onoting'ono m'chilengedwe, ndipo pamapeto pake timapanga mpweya woipa ndi madzi.Simayipitsa chilengedwe, chomwe chimapindulitsa kwambiri kuteteza chilengedwe ndipo chimadziwika kuti ndi zinthu zoteteza chilengedwe.China PP Nonwoven Fabric Price

PLA,zofanananso ndi mtundu wina waPET spunbond,ali ndi drapability kwambiri, kusalala, mayamwidwe chinyezi ndi permeability mpweya, zachilengedwe bacteriostasis ndi khungu kutsimikizira asidi ofooka, kukana kutentha ndi UV kukana.

PLA zonse zolembedwa ngati :polylactic acid

Polylactic acid, yomwe imadziwikanso kuti polylactide, ndi ya banja la polyester.Polylactic acid (PLA) ndi polima wopangidwa ndi polymerization wa lactic acid monga zopangira zazikulu.Zopangira zopangira ndizokwanira ndipo zitha kubwezeretsedwanso.Amagwiritsa ntchito chimanga ndi chinangwa ngati zipangizo.Kapangidwe ka PLA sikumayipitsidwa, ndipo mankhwalawo amatha kusinthidwa kuti azindikire kuzungulira kwachilengedwe, chifukwa chake ndizinthu zobiriwira zobiriwira za polima.

asidi Polylactic ali wabwino matenthedwe bata, processing kutentha 170 ~ 230 ℃, zabwino zosungunulira kukana, akhoza kukonzedwa m'njira zosiyanasiyana, monga extrusion, kupota, biaxial kutambasula, jekeseni kuwomba akamaumba.Zopangidwa ndi polylactic acid sizongowonongeka zokha, komanso zimakhala ndi biocompatibility yabwino, gloss, transparency, kumva komanso kukana kutentha.Amakhalanso ndi kukana kwa bakiteriya, kutentha kwa moto ndi kukana kwa UV, kotero amagwiritsidwa ntchito kwambiri ngati zipangizo zopangira, ulusi ndi nonwovens, etc. Pakalipano, amagwiritsidwa ntchito makamaka mu zovala (zovala zamkati, zakunja), mafakitale (zomangamanga, ulimi, nkhalango. , kupanga mapepala) ndi zachipatala ndi zaumoyo.
