BBCA polylactic acid zvipfeko zvitsva zvigadzirwa

Polylactic acid (PLA) imhando yezvinhu zvitsva izvo zvinogadzirwa nekuwedzera polymerization yelactic acid kubva kune starch kana shuga kuviriswa. Iyo haishandise petroleum seyakagadzirwa zvinhu, uye ine hunhu hwekudzivirira kwezvakatipoteredza, isiri-chepfu, inorwisa mabhakitiriya, inodzoreredza moto, yakanaka biocompatibility uye biodegradability. Ndiyo inonyanya kuvimbisa zvinhu zvitsva kuzunungusa nzvimbo yechinyakare yepetroleum yakavakirwa mapurasitiki uye kemikari fiber mune ramangwana.

Polylactic asidhi uye zvigadzirwa zvayo zvine zvakagadzikana zvemuviri zvimiro pasi peyakajairika tembiricha uye humidity mamiriro. Iyo yakasvibiswa zvachose biomaterial, iyo inogona kushandiswazve. Mushure mekuraswa, inogona kuderedzwa kuita kabhoni dhaikisaidhi nemvura. Mushure me photosynthesis nemiti, inogona kutorwa nemiti zvakare uye kupinda mudenderedzwa rechisikigo nekusingaperi. Iyo "iyo yezvekudzokorodza nharaunda yezana ramakore rechi21".

Hunhu hukuru ndehwekutevera

(1) zviwanikwa zvinogonekazve: kunyanya kubva kuchibage, mbatatisi nezvimwe zvirimwa zvestarch, pamwe nemashanga ezvirimwa, nezvimwe;

(2) biodegradation yakakwana: inogona kutorwa uye kuumbwa nemuviri wemunhu; zvigadzirwa zvakasvibiswa zvachose mu CO2 uye H2O muvhu kana mvura yegungwa mushure mekuraswa mumarara mukati megore rimwe chete, kuziva iyo carbon cycle pamusoro pepamusoro uye nekubudirira kushandura kusvibiswa kwezvakatipoteredza kunokonzerwa ne petroleum based materials;

(3) kushamwaridzana kwemuviri wevanhu uye kuchengeteka: mbishi lactic acid inowanikwa mumuviri womunhu, PLA inogona kushandiswa uye inobatwa nemuviri wemunhu, PLA ndeye FDA inopupurirwa yekugadzirwa kwevanhu, iyo yakashandiswa zvakanyanya munharaunda yezvokurapa kwemakumi emakore;

(4) yakanakisa processability: inogona kugadziriswa nenzira dzakawanda, senge extrusion, kuruka, biaxial kudhirowa, jekiseni kuvhuvhuta;

(5) natural antibacterial and anti mite: the antibacterial and anti mite rate of Candida albicans, Escherichia coli uye Staphylococcus aureus yakasvika kupfuura 95%;

(6) kudzoserwa kwemoto chaiwo: kuchengetedzeka uye kudzoreredza murazvo, utsi hushoma, hapana utsi hutema uye gasi rine chepfu;

(7) yakanakisa kupenya, kujeka, mubato, UV kuramba, hunyoro conductivity, hapana mwando kuwanazve, nezvimwe.

Polylactic acid inogona kugadzirwa kuita polylactic asidhi fiber, uye kuita kwayo kunofananidzwa nekotoni. Pamusoro pezvo, polylactic acid ine kuita kwakafanana kune yakajairika makemikari zvinhu senge polypropylene (PP), polyethylene (PE), polyester fibers (PET, PTT, PBT). Inogona kugadziriswa nekuumbwa kwejekiseni, extrusion, kutenderera uye mamwe maitiro ekugadzira fiber, mafirimu, mapepa uye mahwendefa, zvishoma nezvishoma kutsiva Petrochemical fibers uye petroleum mapurasitiki, Inoshandiswa zvakanyanya mukupfeka, kurongedza, kurima, imba, auto parts, 3D kudhinda, biomedicine nemamwe akawanda minda.
