Polylactic acid (PLA), inozivikanwawo sepolylactide, is an aliphatic polyester yakagadzirwa ne dehydration polymerization yelactic acid inogadzirwa ne microbial fermentation semonomer.Inoshandisa biomass inogona kudzokororwa sechibage, nzimbe, uye mufarinya semidziyo yakabikwa, uye ine zvakawanda zvakasiyana-siyana uye inogona kuvandudzwa.Iyo nzira yekugadzira ye polylactic asidhi yakaderera-kabhoni, inoshamwaridzana nenharaunda, uye kushoma kusvibisa.Mushure mekushandiswa, zvigadzirwa zvayo zvinogona kuumbwa uye kuderedzwa kuti zvione kutenderera mune zvakasikwa.Pamusoro pezvo, inoshandiswa zvakanyanya uye ine mutengo wakaderera pane mamwe akajairika mapurasitiki anoparara akadai sePBAT, PBS, uye PHA.Naizvozvo, yave yakanyanya kushanda uye inokurumidza kukura biodegradable zvinhu mumakore achangopfuura.
Kugadzirwa kwepolylactic acid kunokosheswa pasi rose.Muna 2019, iyo yepasi rose PLA mashandisirwo makuru mukurongedza uye tafuraware, kurapwa uye kuchengetwa kwemunhu, zvigadzirwa zvemufirimu, uye mamwe misika yemagumo akaverengera 66%, 28%, 2%, uye 3% zvakateerana.
Iko kushandiswa kwemusika kwepolylactic acid kuchiri kutungamirwa nekuraswa tafuraware uye chikafu chekurongedza nehupenyu hupfupi hwesherufu, ichiteverwa nehafu-yakasimba kana yakawanda-kushandisa tableware.Zvigadzirwa zvemafirimu zvinoputika semabhegi ekutenga uye mulch zvinotsigirwa zvakanyanya nehurumende, uye saizi yemusika inogona kunge iine kusvetuka kukuru munguva pfupi.Musika wezvigadzirwa zvefiber zvinoraswa zvakaita semanapukeni nemanapukeni ehutsanana anogonawo kukwira zvakanyanya pasi pezvinodiwa nemirairo, asi tekinoroji yayo yemubatanidzwa ichiri kuda budiriro.Zvigadzirwa zvakakosha, senge 3D kudhindwa mune diki asi yakakwira kukosha, uye zvigadzirwa zvinoda kushandiswa kwenguva refu kana kwepamusoro-tembiricha, semagetsi nemidziyo yemotokari.
Inofungidzirwa kuti gore negore kugadzirwa kwepolylactic acid pasi rose (kunze kweChina) inenge 150,000 matani uye gore negore rinobuda rinenge 120,000 matani asati asvika 2015. Maererano nemusika, kubva 2015 kusvika 2020, misika yepasi rose yepolylactic acid ichakura nokukurumidza. pamwero wepagore wekukura ungangoita 20%, uye tarisiro yemusika yakanaka.
Maererano nematunhu, United States ndiyo yakakura yekugadzirwa kwepolylactic acid, inoteverwa neChina, ine mugove wemusika wekugadzira we14% muna 2018. Maererano nekushandiswa kwenharaunda, United States ichiri kuchengetedza nzvimbo yayo inotungamira.Panguva imwe cheteyo, ndiro zvakare guru rekutengesa kunze kwenyika.Muna 2018, musika wepasi rose wepolylactic acid (PLA) waikosheswa paUS$659 miriyoni.Sepurasitiki inoparara ine kuita kwakanakisa.Market insiders vane tarisiro pamusoro pemusika weramangwana
