"Low carbon living" yave musoro wenyaya munguva itsva.Mumakore achangopfuura, kuchengetedza zvakasvibirira kwezvakatipoteredza, kuchengetedza simba, uye kuderedza kubuda kwemhepo zvakapinda muchiratidzo cheveruzhinji zvishoma nezvishoma, uye zvave zvakare maitiro matsva anotsigirwa uye anowedzera mukurumbira munzanga.Munguva yakasvibirira uye yakaderera-kabhoni, kushandiswa kwezvigadzirwa zvebiodegradable kunoonekwa sechiratidzo chakakosha chehupenyu hwepasi-kabhoni, uye inoremekedzwa zvakanyanya uye inoparadzirwa.
Nekuwedzera kwekukurumidza kwehupenyu, mabhokisi epurasitiki anoraswa efuro, mabhegi epurasitiki, zvimiti, makapu emvura nezvimwe zvinhu zvave kuwanikwa kwese muhupenyu.Kusiyana nemapepa, machira uye zvimwe zvinhu, zvigadzirwa zvepurasitiki zvinoraswa mumasikirwo uye zvakaoma kuderedzwa.Kunyange zvichiunza kurerukirwa kuhupenyu hwevanhu, kushandisa zvakanyanya kunogona kukonzera "kusvibiswa kwechena".Muchirevo chechinyorwa chino, biodegradable biomaterials yakabuda.Zvigadzirwa zveBiodegradable zvinhu zviri kubuda zvine mabhenefiti akakosha maererano nekuita kwezvakatipoteredza zvichienzaniswa nezvigadzirwa zvepurasitiki zvinoraswa.Zvigadzirwa zvinogadzirwa zvichishandisa biodegradable biomaterials sezvimisikidzwa zvine nzvimbo yakakura yemusika uye inove yakakosha mutakuri weiyo fashoni yakaderera-kabhoni mararamiro ehupenyu.
Kune marudzi akawanda ezvigadzirwa zvinoodeka, kusanganisiraPCL, PBS, PBAT, PBSA, PHA,PLGA, PLA, etc. Nhasi tichatarisa pane iri kubuda biodegradable material PLA.
PLA, inozivikanwawo sepolylactic acid, CAS 26023-30-3isitashi mbishi zvinhu zvinoviriswa kugadzira lactic acid, inozoshandurwa kuita polylactic asidhi kuburikidza nemakemikari synthesis uye ine biodegradability yakanaka.Mushure mekushandiswa, inogona kuderedzwa zvachose nehutachiona muzvisikwa, pakupedzisira ichigadzira kabhoni dhaikisaidhi nemvura pasina kusvibisa nharaunda.Mamiriro ekunze akanaka kwazvo, uye PLA inozivikanwa sechinhu chine hushamwari hwezvakatipoteredza chine zvinhu zvakanakisa zvipenyu.
Iyo mikuru yemidziyo yePLA inovandudzwa yechirimwa mafibhi, chibage uye zvimwe zvekurima uye zveparutivi zvigadzirwa, uye PLA ibazi rakakosha rezvinhu zvinogara zvichibuda.PLA ine yakasarudzika zvivakwa maererano nekuoma uye pachena.Iyo ine yakasimba biocompatibility, yakafara application renji, yakasimba yemuviri uye mechaniki zvivakwa, uye inosangana nemhando dzakasiyana dzekushandisa.Inogona kushandiswa nenzira dzakasiyana-siyana dzekugadzirwa kwakakura, ine antibacterial rate ye 99.9%, zvichiita kuti ive iyo inonyanya kuvimbisa zvinhu zvinoparara.
Polylactic asidhi (PLA)chinhu chitsva chine hushamwari kwezvakatipoteredza uye chakasvibira biodegradable zvinhu zvinogadzirwa kubva kulactic acid seyakabikwa;Mumakore achangopfuura, PLA yakashandiswa kune zvigadzirwa neminda senge mashanga, tableware, firimu kurongedza zvinhu, faibha, machira, 3D kudhinda zvinhu, etc. PLA zvakare ine hukuru hwebudiriro muminda yakadai semidziyo yekubatsira yekurapa, zvikamu zvemotokari, zvekurima. , masango, uye kuchengetedza kwezvakatipoteredza.
Iyo PLA yakagadzirwa naUnilong Industryndiyo yekupedzisira mune yega polylactic asidhi "particle".Kuburikidza nekusarudzwa kwakasimba kwemhando yepamusoro yepolylactic acid raw materials, PLA polylactic acid plastiki uye PLA polylactic acid fiber inoshandiswa kugadzira hutano, hushamwari hweganda, hwemhando yepamusoro, uye yakasimba antibacterial petroleum based plastic substitutes.Zvigadzirwa zvaro zvikuru zvinosanganisira zvipfeko zvemazuva ano, shangu neheti, tafura, makapu nemaketero, zvekunyorera, matoyi, machira epamba, mbatya dzekuvhara dzinovhara uye bhurugwa, zvinhu zvemumba, zvipukuta zvakaoma uye zvakanyorova, nemimwe minda ine hukama nehupenyu hwedu hwezuva nezuva.
Kubuda kwePLAinogona kubatsira vanhu kuti vagare kure nekusvibiswa kwechena, kuderedza kukuvadzwa kwepurasitiki, uye kukurudzira kuzadzikiswa kwekabhoni peak uye kusarerekera kabhoni.Chinangwa cheUnilong Indasitiri ndeye "kufambirana nekufamba kwenguva, kurarama hupenyu hune hushamwari kwezvakatipoteredza", kusimudzira zvine simba zvigadzirwa zvinoora, kuita kuti vanhu vadye zvine hutano uye vararame hupenyu hune hutano, kurega biodegradation ipinde zviuru zvedzimba, kutungamira maitiro matsva hupenyu hwegirini uye hwakaderera-kabhoni, uye zvizere kupinda muhupenyu hwepasi-kabhoni.
