Chii chinonzi PLA Nonwoven uye Chishandiso Chayo?

Zhejiang Yanpeng Nonwoven Machinery Co., Ltd inyanzvi yekugadzira inyanzvi mukutsvagisa nekusimudzira mitsara yekugadzira isina-kurukwa. Kubva pakutanga kwa2008, isu taigara takatarisa kune isiri-yakarukwa munda. Kusvika nhasi, takashandira vatengi vanopfuura mazana maviri kumba nekune dzimwe nyika, uye takaisa anopfuura mazana matanhatu asina kurukwa mitsetse yekugadzira pasi rese.

Zvigadzirwa zvedu zvikuru zvinosanganisira: PP spunbond isiri yakarukwa yekugadzira mutsara, meltblown isiri-yakarukwa yekugadzira mutsara, spunmelt composite nonwoven yekugadzira mutsara (seSMS, SMMS, SSMMS, SMMMS ... nezvimwewo), Polyester (PET) isiri yakarukwa jira rekugadzira mutsara nezvimwe. zvinobudirira kuvhura iyo PLA/RPET isina kuruka machira ekugadzira mutsara muna 2021.

PLA ndechimwe chezvinhu zvakanyanya kudzidzwa biodegradable zvinhu kumba nekune dzimwe nyika. Kurapa, kurongedza uye fiber ndiwo matatu anonyanya kufarirwa mashandisirwo minda. PLA, ine lactic acid kubva kune yakasarudzika masosi, ine yakanaka biodegradability uye biocompatibility, uye hupenyu hwayo kutenderera kuremedza pane zvakatipoteredza yakadzikira zvakanyanya pane iyo petroleum-based materials, iyo inoonekwa seyakanyanya kuvimbisa yakasvibira yekurongedza zvinhu.

Machira asina kurukwa ane echisikigo anovandudzwa chirimwa zviwanikwa zvepoly (lactic acid) (PLA) seyakabikwa, inoderedza kutsamira pane yechinyakare zviwanikwa zveoiri, zvinoenderana nezvinodiwa zvekusimudzira kwakasimba kwenharaunda yepasirese, ine zvakanakira zvekugadzira faibha uye faibha yechisikigo, panguva imwe chete iine huwandu hwakazara hwekutenderera kwechisikigo uye biological kuora hunhu, zvine chekuita neyakajairwa indasitiri, chibage chine faibha yakawanda yakawana zvivakwa zvakawanda. kutarisa.

1. Chii chinonzi PLA Spunbond Nonwoven Fabric?

PLA, inozivikanwawo sepolylactic acid fiber, ine yakanakisa kudonhedza, kutsvedzerera, kunyudza hunyoro, yakasikwa antibacterial uye ganda rinozorodza isina kusimba asidhi, yakanaka kupisa kupisa uye UV kuramba. Fiber yacho haishandisi petroleum kana mamwe makemikoro, uye tsvina yayo inogona kukamurwa kuita mvura necarbon dioxide neutachiona huri muvhu nemvura yomugungwa, izvo zvisingasvibisi mhoteredzo yepasi. Sezvo yekutanga mbishi yefiber iyi iri starch, kutenderera kwayo kupfupi, ingangoita 1 kusvika kumakore maviri, uye zviri mumhepo zvayo zvinogona kuderedzwa nechirimwa photosynthesis. Kupisa kwekupisa kwePLA fiber inenge chikamu chimwe muzvitatu cheiyo polyethylene uye polypropylene.

Nekuvandudzwa kwekuziva kwevanhu nezvekuchengetedzwa kwezvakatipoteredza, kushandiswa kwezvinhu zvakadzokororwa mune nonwovens kwave kutsva maitiro. PLA isina-yakarukwa jira yakakurudzirwa nenyanzvi dzakawanda se "chinhu chitsva chekugadzirisa kwezvakatipoteredza muzana remakore rechi21" nekuda kwekuvandudzwa kwayo uye kuora. Imhando ye ecological fiber ine yakakura budiriro mukana.

1. Zvigadzirwa zvekuchengetedzwa kwezvakatipoteredza: giredhi yezvokudya, kuchengetedza kwezvakatipoteredza uye hutano, husina fluorescent agent, pasina azo, formaldehyde, PCP, masere masimbi anorema (lead, cadmium, barium, chromium, antimony, selenium, arsenic, mercury);
2. Kugadzirwa kwechigadzirwa kwakakwirira uye kwakagadzikana: yakanakisa kupenya, multifunctional bhegi rekubika uye frying;
3. Izvo zvinhu zvakakora uye furo rinopikisa, rinogona kushandiswa kakawanda; Hazviparadzi zvakatipoteredza. Inogona kuumbwa uye kuvigwa muvhu. Pasi pekuita kweimwe tembiricha nehunyoro uye tupukanana, inogona kuderedzwa zvachose mukati merinenge gore uye pakupedzisira yakaora kuita kabhoni dhaikisaidhi nemvura.
4. Kusimba kwemuviri: kushushikana kwakasimba, kukwirira kupfeka kusagadzikana, kunaka kunyorova conductivity uye kufema kwemhepo, kuchena uye hutsanana.

2. Chii Chinonzi Kushandiswa kwePLA Spunbond Nonwoven Fabric?

Polylactic acid fiber inogadzirwa neakasikwa uye inogona kuvandudzwa chirimwa zviwanikwa, izvo zvinoderedza kutsamira kune yechinyakare petroleum zviwanikwa uye inosangana nezvinodiwa zvekusimudzira nharaunda yepasirese. Chibage fiber ine zvakanakira zvese zviri zviviri synthetic fiber uye yakasikwa faibha, uye ine hunhu hwekutenderera kwechisikigo kuzere uye biodegradability. Kuenzaniswa nemidziyo yechinyakare, fiber yechibage ine akawanda akasiyana zvivakwa, saka yakatariswa zvakanyanya neindasitiri yemachira. Iwo anoshandiswa zvakanyanya mu biodegradable semabhegi ekuzvinamira, biological degradation ye zipper bag, biological degradable mabhegi, biodegradable mabhegi, biodegradable tsvina mabhegi uye biodegradable isiri-yakarukwa (chikafu kurongedza, bhegi remwaka, bhegi reti, mask, kumeso, tafura yekushandisa. jira, zvipfeko zvekuvhiya zvinoraswa, napkin yehutsanana, bhegi risina guruva, bhegi remuti regwenga, jira resefa), nezvimwe.
