Mashandisiro edu emazuva ese emasks echiso ari kushanduka zvishoma nezvishoma kuita sosi huru yekusvibisa chena mushure memabhegi emarara.
Ongororo ye2020 inofungidzira kuti mabhiriyoni zana nemakumi maviri nematatu emeso emeso anodyiwa mwedzi wega wega, mazhinji acho ari masiki anoraswa anogadzirwa kubva kumapurasitiki microfiber.Nedenda reCCIDID-19, masks anoraswa akasimudzirwa munyika zhinji kudzivirira hutachiona hweCCIDID-19 nekuti anogona kubatsira kudzivirira kupararira kweCCIDID-19 nezvimwe zvirwere, zvichiita kuti iyi data igare yakagadziridzwa.
Nekudaro, mumamiriro ezvinhu akadai ekushandiswa kwepamusoro, hapana nyika yakaita "zvepamutemo" nhungamiro yekudzokorodza kwemasks, izvo zvinotungamira mukuraswa kwakawanda kwemasiki akaraswa semarara akasimba, izvo zvinounza dambudziko rakakura kukudzora kusvibiswa kwepurasitiki.
Kutsvaga mhinduro yakagadzikana kudambudziko repasi rose rekusvibiswa kwepurasitiki rinokonzerwa nemasiki anoraswa kwakakosha.
Nguva pfupi yadarika, vaongorori vaviri vebiotechnology kubva kuGazamada University vakakurudzira kuti tsvina ine chekuita nedenda inogona kuraswa nemasiki anoraswa anoraswa akagadzirwa nemashizha epineapple.
Iyo biodegradable masks anoraswa anonyanya kugadzirwa neshinda kubva pamashizha epineapple, uye nekuti anoshandisa tambo dzechisikigo pachinzvimbo chepurasitiki fiber, tupukanana senge fungi kana mabhakitiriya anogona kutanga maitiro ekuora nekukurumidza mushure mekunyudzwa muvhu (inotarisirwa kutora mazuva matatu).
Mufananidzo |Pineapple leaf fiber production process: kurima mananasi (A), pineapple fruit (B), faibha yakatorwa kubva pamashizha epineapple (C), pineapple leaf fiber inogadzirwa kuIndonesia (D) (Kwakabva: Hindawi).
Zvinonzwisiswa kuti pineapple inowanikwa zvakanyanya munzvimbo dzinopisa, ruzivo rwakakodzera runoratidza kuti kugadzirwa kwepineapple yepasi rose kwakasvika 27.82 miriyoni matani muna 2020. Pineapple Mashizha ane imwe yepamusoro inozivikanwa yefiber fiber content (pedyo ne80%), uye ikoko. inzira dzakawanda dzekubvisa faibha kubva pamashizha epineapple, kuita pineapple leaf fiber inoonekwa seyakanaka imwe nzira kune epurasitiki fiber nevaongorori vebiotechnology.
Mufananidzo |Nyika dzinotungamira mukugadzirwa kwemaananasi muna 2020, pakati pawo Philippines, Costa Rica neBrazil ndidzo makambani makuru matatu epasi rose anogadzira mananasi (kunobva: Statista).
Pineapple leaf fibers machena, ane filamentous sheen, ane simba rakanyanya kusimba, ane magadzirirwo akatsetseka kupfuura mamwe mashizha emiti (akadai sehemp, jute, flax, uye canna), uye ari nyore kusvibisa.Pineapple leaf fibers inorongwa nenzira yakafanana nekotoni, asi iyo inonyanya kukoshesa zvakatipoteredza kupfuura donje.
Donje rinorimwa pachivanhu nemishonga yekuuraya zvipembenene nefetereza, uye rinogadzirwa nemishonga yakaoma, imwe yacho inosara isingagezwe.Mashizha epineapple, kune rumwe rutivi, anokura pasina chero anowedzera uye anogona kuvandudzwa gore negore uye nyore kuwanikwa.
Parizvino, mashizha akawanda epineapple anogadzirwa gore negore, kunze kwechikamu chiduku chinogadzirwa mupineapple leaf fiber uye inoshandiswa mumagetsi uye kugadzirwa kwesimba (zvakadai sekugadzira tambo, twine, zvinhu zvinosanganiswa uye zvigadzirwa zvekupfeka).Kazhinji inoraswa semarara ekurima, kushandiswa zvine musoro kwemashizha epineapple hakuzongodzikisi kusvibiswa kwezvakatipoteredza, asiwo kunounza humwe hupfumi.
Akakosha sei masks anogona kuraswa anogona kuraswa kuvanhu?Mask yekuvhiya yakajairika inoraswa ine matatu akaturikidzana epolymer.Iyo yekunze dhizaini ichinhu chisina kunyura (senge polyester), iyo yepakati jira risiri rakarukwa (senge polypropylene nepolystyrene) rakagadzirwa nekunyungudutswa-kuvhuvhuta, uye mukati memukati chinhu chinonwa sedonje. .Polypropylene, iyo inonyanya kushandiswa mukugadzirwa kwemasiki, yakaoma kuputsa zvekuti inogona kuramba iri munzvimbo yezvakatipoteredza kwemakumi emakore, uye pamwe mazana emakore, kushanduka kuita microplastics uye nanoplastics.
Pamusoro pekukonzera kusvibiswa kwepurasitiki, masks akaraswa anogona kutounganidza nekuburitsa makemikari anokuvadza nezvinhu zvipenyu, zvakaita seBisphenol A (BPA), heavy metals, uye pathogenic microorganisms.Pakati pavo, bisphenol A yakaratidzirwa kuve necarcinogenic effect.
Pamusoro pezvo, zvimwe zvidzidzo zvakaratidza kuti masiki anogona kutakurwa kubva pasi kuenda kumvura yakachena uye nzvimbo dzeMarine kuburikidza nekumhanya kwepamusoro, kubuda kwenzizi, mafungu egungwa, mhepo, uye mhuka (kuburikidza nekupinzwa kana kupinza) kana isina kuunganidzwa nemazvo.Sekureva kwe2020 mushumo neOceansAsia, "Inofungidzirwa mabhiriyoni 1.56 emasiki echiso achapinda mugungwa muna 2020, zvichikonzera kuwedzera 4,680 kusvika 6,240 matani ekusvibiswa kwepurasitiki yeMarine."

Zvinogona kutaurwa kuti nekukura kwakajairwa kwedenda, kutambisa kwemasiki kunongounganidza zvakanyanya, uye kusvibiswa kwemhoteredzo yezvakatipoteredza kuchawedzera uye kukuru.Masks anoraswa akagadzirwa nepineapple leaf fibers, ayo anodzikisira zvakasikwa uye asingabudise huturu hunokuvadza, inogona kuve mhinduro yekusvibiswa kwepurasitiki kunokonzerwa nemasiki.
Nekudaro, nekuda kweiyo hydrophilic chimiro chepineapple leaf fiber, haina kusimba uye yakasimba sepurasitiki.Kutsvakurudza kwakawanda kunodiwa kugadzirisa dambudziko iri.
