"Kurarama nekabhoni shoma" kwave nyaya huru munguva itsva. Mumakore achangopfuura, kuchengetedzwa kwezvakatipoteredza zvine girini, kuchengetedza simba, uye kuderedza utsi hwemhepo zvakapinda zvishoma nezvishoma mumaonero everuzhinji, uye zvavewo tsika itsva inotsigirwa uye iri kuwedzera kufarirwa munharaunda. Munguva yegirini nekabhoni shoma, kushandiswa kwezvinhu zvinoora kunoonekwa sechiratidzo chakakosha chehupenyu hune kabhoni shoma, uye kunoremekedzwa uye kuparadzirwa zvakanyanya.
Nekukurumidza kwehupenyu, mabhokisi epurasitiki efoam anoraswa, mabhegi epurasitiki, zvimiti, makapu emvura nezvimwe zvinhu zvave kuwanikwa muhupenyu. Kusiyana nemapepa, machira nezvimwe zvinhu, zvigadzirwa zvepurasitiki zvinoraswa uye zvakaoma kuora. Kunyange zvazvo zvichiunza nyore kuhupenyu hwevanhu, kushandiswa zvakanyanya kunogonawo kukonzera "kusvibiswa kwechena". Mumamiriro ezvinhu aya, zvinhu zvipenyu zvinoora zvakabuda. Zvinhu zvinoora zvakabuda zvinhu zvine zvakanakira zvakakosha maererano nekushanda kwezvakatipoteredza zvichienzaniswa nezvinhu zvepurasitiki zvinoraswa zvechinyakare. Zvigadzirwa zvinogadzirwa uchishandisa zvinhu zvinoora zvakaora sezvinhu zvisina kugadzirwa zvine nzvimbo yakakura yemusika uye zvinova kutakura kwakakosha kwepfungwa yehupenyu hwefashoni husina kabhoni yakawanda.
Kune mhando dzakawanda dzezvinhu zvinoora, zvinosanganisiraPCL, PBS, PBAT, PBSA, PHA,PLGA, PLA, nezvimwewo. Nhasi tichatarisa pane zvinhu zvinoora zviri kubuda muPLA.
PLA, inozivikanwawo sepolylactic acid, CAS 26023-30-3chinhu chisina kubikwa chestarch chinoviriswa kuti chigadzire lactic acid, iyo inozoshandurwa kuita polylactic acid kuburikidza nekugadzirwa kwemakemikari uye ine mukana wakanaka wekuora. Mushure mekushandiswa, inogona kuora zvachose netupukanana turi muzvisikwa, pakupedzisira ichigadzira kabhoni dioxide nemvura pasina kusvibisa nharaunda. Nzvimbo yacho yakanaka kwazvo, uye PLA inozivikanwa sechinhu chine hushamwari kune nharaunda chine hunhu hwakanaka hwezvipenyu.
Zvinhu zvikuru zvePLA ifiber yezvirimwa zvinodzorerwa, chibage nezvimwe zvigadzirwa zvekurima nezvekunze, uye PLA ibazi rakakosha rezvinhu zvinoora zvinobuda. PLA ine hunhu hwakasiyana maererano nekuomarara uye kujeka. Inoenderana zvakanyanya nehupenyu, ine mhando dzakasiyana dzekushandiswa, hunhu hwakasimba hwemuviri uye hwemakanika, uye inosangana nezvinodiwa zvakasiyana-siyana zvekushandiswa. Inogona kushandiswa munzira dzakasiyana-siyana dzekugadzira zvinhu zvakakura, ine huwandu hwe99.9% hwemabhakitiriya, zvichiita kuti ive chinhu chinoora chinovimbisa zvikuru.
Asidhi yePolylactic (PLA)chinhu chitsva chine hushamwari kune nharaunda uye chinoora chegirini chinogadzirwa kubva ku lactic acid sezvinhu zvakabikwa; Mumakore achangopfuura, PLA yakashandiswa kune zvigadzirwa neminda zvakaita semashanga, zvinwiwa zvetafura, zvinhu zvekurongedza mafirimu, fibers, machira, zvinhu zvekudhinda zve3D, nezvimwewo. PLA ine mukana mukuru wekuvandudza minda yakaita semidziyo yekurapa inobatsira, zvikamu zvemotokari, kurima, masango, uye kuchengetedzwa kwezvakatipoteredza.
Iyo PLA yakagadzirwa naIndasitiri Yesendiyo yakanakisisa mu "particle" yega yega yepolylactic acid. Nekusarudzwa kwakasimba kwezvinhu zve polylactic acid zvemhando yepamusoro, PLA polylactic acid plastic uye PLA polylactic acid fiber zvinoshandiswa kugadzira zvinhu zvine hutano, zvinodzivirira ganda, zvemhando yepamusoro, uye zvakasimba zvinorwisa mabhakitiriya zvinobva mupetroleum. Zvigadzirwa zvayo zvikuru zvinosanganisira mbatya dzemazuva ano, shangu nengowani, ndiro dzekudya, makapu nemaketero, zvekushandisa pakunyora, matoyi, machira epamba, mbatya nemabhurugwa anokwana, zvinhu zvemumba, machira akaoma uye akanyorova, nezvimwe zvine chekuita nehupenyu hwedu hwezuva nezuva.
Kubuda kwePLAzvinogona kubatsira vanhu kuti vasasvibiswe nechinhu chichena, kuderedza kukuvara kwepurasitiki, uye kukurudzira kuzadzikiswa kwakakwana kwehuwandu hwecarbon peak uye carbon neutrepreneurship. Chinangwa cheUnilong Industry ndecheku "fambirana nenguva, kurarama hupenyu husingakuvadzi zvakatipoteredza", kukurudzira zvakasimba zvigadzirwa zvinoora, kuita kuti vanhu vadye zvine hutano uye vararame hupenyu hune hutano, kurega kuora kwebiogradation kuchipinda muzviuru zvemhuri, kutungamira maitiro matsva ehupenyu hwegirini necarbon low, uye kupinda muhupenyu hwecarbon low.
