1. Pfupiso yecheni yeindasitiri:
Zita rakazara re polylactic acid ipolylactic acid kana polylactic acid. Ipolyester ine mamorekuru akawanda inowanikwa nepolymerization nelactic acid kana lactic acid dimer lactide semonomer. Ndeyezvinhu zvakagadzirwa zvine mamorekuru akawanda uye ine hunhu hwe biological basis uye kuora. Parizvino, polylactic acid ipurasitiki inoora ine maindasitiri akakura zvakanyanya, inoburitsa zvakawanda uye inonyanya kushandiswa pasi rose. Indasitiri yepolylactic acid ine marudzi ese ezvinhu zvakakosha, zvakaita sechibage, nzimbe, shuga beet, nezvimwewo, pakati payo pakagadzirwa polylactic acid, uye pasi payo panonyanya kushandiswa polylactic acid, kusanganisira midziyo yekudzivirira nharaunda, kurongedza nharaunda, nezvimwewo.
2. Indasitiri yepamusoro
Parizvino, zvinhu zvakagadzirwa neindasitiri yepolylactic acid yemuno ilactic acid, uye lactic acid inonyanya kugadzirwa kubva muchibage, nzimbe, shuga beet nezvimwe zvigadzirwa zvekurima. Nokudaro, indasitiri yekudyara zvirimwa inotungamirwa nechibage ndiyo indasitiri yepamusoro ye polylactic acid industrial chain. Kubva pamaonero enzvimbo yekubereka chibage nekudyara yeChina, goho rekudyara chibage muChina richasvika matani mamiriyoni 272.55 muna 2021, nehukuru hwakakura, uye nzvimbo yekudyara yave yakagadzikana pamahekita mamiriyoni 40-45 kwemakore mazhinji. Kubva pakuwanikwa kwechibage kwenguva refu muChina, zvinogona kutarisirwa kuti goho rechibage richaramba rakagadzikana mune ramangwana.
Kana zviri zvimwe zvinhu zvinogona kushandiswa kugadzira lactic acid, zvakaita senzimbe neshuga beet, huwandu hwese hweChina hwaiburitsa muna 2021 hwaive matani mamiriyoni 15.662, izvo zvaive zvakaderera pane zvakaitika mumakore apfuura, asi zvichiri padanho rakajairika. Uye mabhizinesi pasi rese ari kutsvagawo nzira itsva dzekugadzira lactic acid, dzakadai sekushandisa shuga inobva muhuni dzakadai sehuswa nesawdust kugadzira lactic acid kana kutsvaga nzira yekushandisa methane kugadzira lactic acid. Pakazara, kuwanikwa kwepolylactic acid muindasitiri yepamusoro kuchave kwakasimba mune ramangwana.
3. Indasitiri yepakati pezvekudyara
Sezvinhu zvinoora zvachose, polylactic acid inogona kuunza magumo ezviwanikwa muhurongwa hwekuvandudza nekudzokorodza zviwanikwa, izvo zvine zvakanakira zvisizvo zvisina zvinhu zvakagadzirwa nepetroleum. Nokudaro, kushandiswa kwepolylactic acid mumusika wemuno kuri kuwedzera. Kushandiswa kwemuno muna 2021 i48071.9 matani, kuwedzera kwe40% gore negore.
Nekuda kwekusakwanisa kugadzira polylactic acid muChina, huwandu hwepolylactic acid inounzwa kunze kwenyika hwakakura kupfuura huwandu hweinounzwa kunze kwenyika. Mumakore achangopfuura, huwandu hwepolylactic acid inounzwa kunze kwenyika hwakawedzera nekukurumidza nekuda kwekudiwa kwemuno. Muna 2021, kuunzwa kwepolylactic acid yakasvika matani 25294.9. Kutengeswa kwepolylactic acid kunze kwenyika kwakaitawo kufambira mberi kukuru muna 2021, kusvika matani 6205.5, kuwedzera kwegore negore kwe117%.
Mushumo wakabatana: mushumo wekuongorora mafambiro ebudiriro uye kufanotaura kwetarisiro yebudiriro yeindasitiri yezvigadzirwa zve polylactic acid muChina kubva muna 2022 kusvika 2028 wakapihwa neZhiyan consulting
4. Indasitiri iri pasi pemvura
Mukushandiswa kwayo kwepasi, polylactic acid yakashandiswa muminda yakawanda ine hunhu hwayo hwezvinhu zvipenyu uye kuora kwayo. Parizvino, yave ichishandiswa zvakanyanya mukuisa chikafu, zvinwiwa, mabhegi efirimu nezvimwe zvigadzirwa neminda. Semuenzaniso, firimu repurasitiki rekurima rakagadzirwa nepolylactic acid rinogona kuora zvachose uye kunyangarika mushure mekukohwa zvirimwa, izvo zvisingaderedzi huwandu hwemvura uye kuorera kwevhu, asiwo kudzivirira mari yekuwedzera yebasa nekushanda inodiwa pakudzoreredza firimu repurasitiki, inova ndiyo nzira yakajairika yekuvandudza firimu repurasitiki muChina mune ramangwana. Nzvimbo yakafukidzwa nefirimu repurasitiki muChina inosvika mahekita 18000, uye kushandiswa kwefirimu repurasitiki muna 2020 matani 1357000. Kana firimu repurasitiki rinoora rave kufarirwa, indasitiri yepolylactic acid ine nzvimbo yakakura yekuvandudza mune ramangwana.
