Polylactic acid isiri-yakarukwa machira emidziyo inogona kusanganisa mabhenefiti ekuita kwepolylactic acid nemaitiro echimiro cheultrafine faibha, hombe chaiyo nzvimbo, uye yakakwirira porosity yezvisiri-zvakarukwa zvemachira, uye zvine tarisiro yakafara yekushandisa mumunda wekusefa kwemhepo.
Kushandiswa kwepolylactic asidhi isina kuruka jiramuindasitiri yekusefa kwemhepo inogona kunyanya kukamurwa kuita mask sefa zvinhu uye zvakatipoteredza zvine hushamwari mafirita (utsi hwemaindasitiri uye kusefa kweguruva, kucheneswa kwemhepo, kuchengetedzwa kwemunhu, nezvimwewo).
Saka, ndezvipi zvakanakira uye maitiro ekushandisa polylactic acid isiri-yakarukwa jira sejiraair filtration material?
Biodegradability
Kune masiki sefa zvinhu, biodegradability chinhu chakakosha hunhu. Iyo yechinyakare mask sefa layer inoshandisa kaviri-layer kunyunguduka yakafefeterwa PP isiri-yakarukwa jira, rinenge risingaparare. Masks akasiiwa, angave achiyerera munzizi nemakungwa kana kuvigwa muvhu, anoisa njodzi huru kune ecosystem.
Iyo mask filter layer yakagadzirwa nepolylactic asidhi zvinhuhaingogone kusefa zvinokuvadza zvinhu zvakaita seguruva uye mabhakitiriya ari mumhepo, asi zvakare kusvibisa mushure mekushandisa uye kuraswa, zvichideredza kudzvanywa kweiyo ecosystem.
Kana zvigadzirwa zvepolylactic acid faibha zvichiiswa munzvimbo dzechisikigo dzine kumwe tembiricha uye hunyoro (sejecha, silt, mvura yegungwa), polylactic acid inogona kunyungudutswa kuita kabhoni dhaikisaidhi nemvura netupukanana. Kana polylactic acid fibers yakavigwa muvhu, nguva yekuparara kwepanyama inenge makore 2-3; Kana polylactic acid fibers yakasanganiswa nemarara ehupenyu uye yakavigwa, inoora mukati memwedzi mishoma.
Polylactic asidhi chigadzirwa tsvina inogona kuparara zvachose kuita kabhoni dhaidhiyo uye mvura pasi peindasitiri composting mamiriro (tembiricha 58 ℃, mwando 98%, uye microbial mamiriro) kwemwedzi 3-6.
Antibacterial uye deodorizing agents
Iyo inonyanya kukosha yepolylactic acid fiber iri mukukwanisa kwayo kwete chete kuwana "fizical filtration", asiwo "biological filtration". Iyo yepamusoro yePLA fiber haina kusimba acidic, iyo inogona kutadzisa kukura kwema microorganisms uye kuderedza kupararira kweaallergen uye mabhakitiriya mumhepo kusvika pamwero wakati. Panyaya ye deodorization, inonyanya kutsamira pane yayo acidity kuparadza sero chimiro chekunhuhwirira chinokonzera mabhakitiriya, kuuraya kunhuhwirira kunokonzeresa mabhakitiriya, uye kuzadzisa mhedzisiro yekunhuhwirira.
Zvichienderana nehunhu uhu, polylactic acid inoraswa biodegradable masks ine yakakosha deodorizing mhedzisiro uye inogona kupfekwa kwenguva yakareba pasina kufema. Inoshandiswa kumidziyo yekusefa mhepo yemumba, mhepo yakasefa yakachena uye haina kunhuhwirira, uku ichinyatso kudzivirira iyo sefa zvinhu kubva mukuvhuvhu uye kunamatira, ichiwedzera hupenyu hwayo hwesevhisi.
Kusefa kuita
Polylactic asidhi faibha dzine zvimwe zvekusefa, uye hunyoro hwadzo hwefiber uye muchinjika-chikamu chimiro chinogona kugadzirwa kukwidziridza kuyerera kwemhepo uye kubatwa kwechikamu, kunyatsosefa kunze tudiki uye zvinosvibisa mumhepo.
Kufema kwepamusoro
Magadzirirwo ekugadzirwa kwepolylactic acid fibers anogona kuwana kufema kwakanyanya, kuve nechokwadi chekuyerera kwemhepo pasina kukanganisa kushanda kwemhepo.
Good tensile simba
Polylactic asidhi faibha ine yakakwira kusimba simba, izvo zvinoita kuti mweya sefa donje igare yakasimba uye isingaite deformation kana kukuvara panguva yekushandiswa.
Simba uye kuoma
Machira asina kurukwa akagadzirwa kubva ku polylactic asidhi fibers anogona kuwana simba repamusoro uye kusimba kwakanyanya kusangana nezvinodiwa zvekupeta zveimwe mamiriro ekushandisa.Nekufambira mberi kwekusimudzira magariro uye hunyanzvi hwekuvandudza tekinoroji muindasitiri yemachira, polylactic acid zvinhu zvine basa rakapfuma zvinopa vashandisi sarudzo dzakawanda.
Dongguan Liansheng Non woven Technology Co., Ltd.yakavambwa muna Chivabvu 2020. Ibhizimusi rekugadzira jira rakakura risingarukwe rinobatanidza tsvakiridzo nekusimudzira, kugadzira, uye kutengesa. Inogona kuburitsa mavara akasiyana-siyana ePP spunbond machira asiri akarukwa ane hupamhi husingasviki 3.2 metres kubva pa9 gramu kusvika 300 magiramu.
