Polypropylene nonwovens anoshandiswa muminda yakawanda senge kurapwa, hutsanana, zvekuzvidzivirira nazvo (PPE), kuvaka, zvekurima, kurongedza, nezvimwe. Zvisinei, nepo vachipa kurerutsira upenyu hwavanhu, ivo vanoisawo mutoro mukuru pamhoteredzo. Zvinonzwisiswa kuti tsvina yaro inotora mazana emakore kuti iparadze zvachose pasi pemamiriro ezvinhu echisikigo, iyo yave iri nzvimbo inorwadza mumhizha kwemakore akawanda. Nekuwedzera kwekuziva kwekuchengetedzwa kwezvakatipoteredza munzanga uye kufambira mberi kweindasitiri yekugadzira tekinoroji, iyo nonwovens indasitiri iri kushingairira kuendesa zvigadzirwa zvinogoneka uye matekinoroji kudzikisa kukanganisa kwezvakatipoteredza.
Kubva muna Chikunguru 2021, maererano neEU's "Directive on Reducing the Environmental Impact yeZvimwe Zvigadzirwa zvePlastiki" (Directive 2019/904), oxidative mapurasitiki anoshatisa akarambidzwa muEU nekuda kwekuparara kwawo kuburitsa microplastic kusvibiswa.
Kutanga kubva Nyamavhuvhu 1, 2023, maresitorendi, zvitoro zvezvitoro, uye masangano eruzhinji muTaiwan, China yakarambidzwa kushandisa tableware yakagadzirwa nepolylactic acid (PLA), kusanganisira ndiro, midziyo yebento, nemakapu. Iyo compost degradation modhi yakabvunzwa uye yakarambwa nenyika zhinji nematunhu.
Kuzvipira kukufema kwevanhu kune hutano uye kupa mweya yakachena nemvura,Medlong JOFOyaitaPP biodegradable nonwoven jira. Mushure mekunge machira avigwa muvhu, ma microorganisms akazvitsaurira anonamatira uye kuumba biofilm, kupinda uye kuwedzera polymer cheni yemucheka usina kuruka, uye kugadzira nzvimbo yekuberekesa kuti ikurumidze kuora. Panguva imwecheteyo, masaini emakemikari anoburitswa anokwezva mamwe ma microorganisms kuti atore chikamu mukudyisa, achivandudza zvakanyanya kuderera kwekuita. Yakaedzwa ichitaura nezve ISO15985, ASTM D5511, GB/T 33797-2017 uye mamwe mazinga, iyo PP biodegradable nonwoven jira ine degradable rate inodarika 5% mukati memazuva makumi mana neshanu, uye yakawana iyo EUROLAB chitupa kubva kusangano rine chiremera chepasi rose. Kuenzaniswa neyechinyakare PPspun bonded nonwovens, PP biodegradable nonwovens inogona kupedzisa kuparara mukati memakore mashoma, ichideredza biodegradation cycle ye polypropylene zvinhu, zvine zvakakosha zvakakosha pakuchengetedza kwezvakatipoteredza.
Medlong JOFO biodegradable PP nonwoven machira anowana kwechokwadi kuparara kwezvakatipoteredza. Munzvimbo dzakasiyana-siyana dzemarara dzakadai semarara, mugungwa, mvura yakachena, sludge anaerobic, high solid solid anaerobic, uye kunze kwekunze kwezvakatipoteredza, inogona kusvibiswa zvachose mukati memakore maviri pasina chepfu kana microplastic residues.
Mumamiriro ekushandiswa kwemushandisi, chitarisiko chayo, zvimiro zvemuviri, kugadzikana uye hupenyu hurefu hwakafanana nemachira echinyakare asiri akarukwa, uye hupenyu hwayo hwesherufu haukanganisi.
Mushure mekunge kutenderera kwekushandisa kwapera, inogona kupinda mune yakajairwa kudzokorodza system uye kudzokororwa kana kushandiswazve kakawanda, izvo zvinosangana nezvinodiwa zvegirinhi, yakaderera-kabhoni, uye denderedzwa kusimudzira.
