Kugwiritsa ntchito polylactic acid sanali nsalu nsalu mu mpweya kusefera zipangizo

Polylactic asidi sanali nsalu nsalu zipangizo akhoza kuphatikiza chibadidwe ntchito ubwino wa asidi polylactic ndi makhalidwe structural ulusi ultrafine, lalikulu enieni pamwamba m'dera, ndi mkulu porosity wa zinthu sanali nsalu nsalu, ndi kukhala ndi chiyembekezo yotakata ntchito m'munda kusefa mpweya.

Kugwiritsa ntchito kwapolylactic asidi sanali nsalu nsalumu mafakitale kusefera mpweya akhoza makamaka kugawidwa mu chigoba fyuluta zipangizo ndi zachilengedwe wochezeka zosefera (utsi mafakitale ndi kusefera fumbi, kuyeretsa mpweya, chitetezo munthu, etc.).

Kotero, ubwino ndi makhalidwe otani ogwiritsira ntchito polylactic acid sanali nsalu nsalu ngati nsaluzinthu zosefera mpweya?

Biodegradability

Pazinthu zosefera chigoba, biodegradability ndizofunikira kwambiri. Chosanjikiza chachikhalidwe cha chigoba chimagwiritsa ntchito nsalu zosanjikiza ziwiri za PP zosawomba, zomwe sizingawonongeke. Masks osiyidwa, kaya akuyenda mumitsinje ndi nyanja zamchere kapena okwiriridwa munthaka, amawopseza kwambiri chilengedwe.

Zosefera za chigoba zopangidwa ndipolylactic asidi zinthusangasefe bwino zinthu zovulaza monga fumbi ndi mabakiteriya omwe ali mumlengalenga, komanso amawononga pambuyo pogwiritsidwa ntchito ndi kutaya, kuchepetsa kupanikizika kwa chilengedwe.
Pamene polylactic asidi CHIKWANGWANI mankhwala poyera chilengedwe chilengedwe ndi kutentha ndi chinyezi (monga mchenga, silt, madzi a m'nyanja), asidi polylactic akhoza kuwola kwathunthu kukhala mpweya woipa ndi madzi ndi tizilombo. Ngati ulusi wa polylactic acid utakwiriridwa m'nthaka, nthawi yakuwonongeka kwachilengedwe ndi pafupifupi zaka 2-3; Ngati ulusi wa polylactic acid usakanizidwa ndi zinyalala za organic ndikukwiriridwa, uwola mkati mwa miyezi ingapo.
Zinyalala za polylactic acid zitha kusungunuka kwathunthu kukhala mpweya woipa ndi madzi pansi pamikhalidwe ya kompositi yamafakitale (kutentha 58 ℃, chinyezi 98%, ndi mikhalidwe ya tizilombo) kwa miyezi 3-6.

Antibacterial ndi deodorizing agents

Zopadera za polylactic acid fiber zimakhala ndi kuthekera kwake kosangopeza "kusefera kwathupi", komanso "kusefera kwachilengedwe". Pamwamba pa PLA CHIKWANGWANI ndi ofooka acidic, amene angalepheretse kukula kwa tizilombo tating'onoting'ono ndi kuchepetsa kufala kwa allergens ndi mabakiteriya mu mlengalenga kumlingo wakutiwakuti. Pankhani ya deodorization, imadalira kwambiri acidity yake kuti iwononge mawonekedwe a cell a fungo loyambitsa mabakiteriya, kupha fungo loyambitsa mabakiteriya, ndikukwaniritsa zotsatira za kununkhira.

Kutengera khalidweli, masks otayika a polylactic acid omwe amatha kutaya fungo amakhala ndi zotsatira zowononga kwambiri ndipo amatha kuvala kwa nthawi yayitali osapumira. Amagwiritsidwa ntchito pazida zosefera mpweya wapanyumba, mpweya wosefedwa ndi watsopano komanso wopanda fungo, pomwe umalepheretsa zinthu zosefera kuti zisawonongeke ndikumamatira, kukulitsa moyo wake wautumiki.

Kusefa

Ulusi wa polylactic acid uli ndi zinthu zina zosefera, ndipo ulusi wawo wowoneka bwino komanso mawonekedwe apakati amatha kupangidwa kuti azitha kuyendetsa bwino mpweya komanso kugwidwa kwa tinthu, ndikusefa tinthu tating'ono ndi zowononga mlengalenga.

Kupuma kwakukulu

Mapangidwe a ulusi wa polylactic acid amatha kupuma kwambiri, kuonetsetsa kuti mpweya ukuyenda bwino popanda kusokoneza kayendedwe ka mpweya.

Mphamvu yabwino yolimbikira

Ulusi wa polylactic acid umakhala ndi mphamvu zolimba kwambiri, zomwe zimapangitsa thonje losefera mpweya kukhala lolimba komanso losawonongeka kapena kuwonongeka pakagwiritsidwa ntchito.

Mphamvu ndi kulimba

Nsalu zosalukidwa zopangidwa ndi ulusi wa polylactic acid zimatha kukhala zamphamvu kwambiri komanso kulimba mtima kwambiri kuti zikwaniritse zofunikira zopindika za zochitika zina zogwiritsira ntchito.

Dongguan Liansheng Non Woven Technology Co., Ltd.idakhazikitsidwa mu Meyi 2020. Ndi bizinesi yayikulu yopanda nsalu yopanga nsalu kuphatikiza kafukufuku ndi chitukuko, kupanga, ndi malonda. Itha kupanga mitundu yosiyanasiyana ya nsalu za PP spunbond zosalukidwa ndi m'lifupi mwake osakwana 3.2 metres kuchokera ku 9 magalamu mpaka 300 magalamu.
