1. Mhedziso yeketani yemaindasitiri:
Zita rakazara repolylactic acid ipoly lactic acid kana poly lactic acid. Iyo yakakwira molecular polyester zvinhu zvakawanikwa nepolymerization ine lactic acid kana lactic acid dimer lactide semonomer. Iyo ndeye yekugadzira yakakwira molecular material uye ine hunhu hwebhayoloji hwaro uye kudzikira. Parizvino, polylactic asidhi ipurasitiki inogona kuparara ine yakanyanya kukura maindasitiri, yakakura kubuda uye inonyanya kushandiswa pasirese. Kumusoro kwepolylactic acid indasitiri ndeye marudzi ese ezvigadzirwa zvekutanga, sechibage, nzimbe, shuga beet, zvichingodaro, pakati inosvika kugadzirwa kwepolylactic acid, uye kuzasi kunonyanya kushandiswa kwepolylactic acid, kusanganisira kuchengetedza kwezvakatipoteredza. tableware, kuchengetedzwa kwezvakatipoteredza kurongedza, nezvimwe.
2. Indasitiri yekumusoro
Parizvino, iyo mbishi yemusha wepolylactic acid indasitiri ndeye lactic acid, uye lactic acid inonyanya kugadzirirwa kubva kuchibage, nzimbe, shuga beet uye zvimwe zvigadzirwa zvekurima. Naizvozvo, indasitiri yekudyara zvirimwa inotongwa nechibage ndiyo indasitiri yekumusoro yepolylactic acid industrial chain. Kubva pamaonero enzvimbo yekurima chibage neChina, chibage chekudyarwa neChina chichasvika 272.55 miriyoni matani muna 2021, nekukura kukuru, uye nzvimbo yekudyara yakagadzikana pa40-45 miriyoni mahekita kwemakore akawanda. Kubva pakugara kwenguva refu kwechibage muChina, zvinogona kutarisirwa kuti kugoverwa kwechibage kucharamba kwakagadzikana mune ramangwana.
Kana zviri zvimwe zvinhu mbishi zvinogona kushandiswa kugadzira lactic asidhi, senge nzimbe uye shuga beet, China yose goho muna 2021 aiva mamiriyoni 15.662 matani, iyo yakanga yakaderera kupfuura makore apfuura, asi vachiri padanho zvakajairika. Uye mabhizinesi kutenderera pasirese ari kutsvagawo nzira nyowani dzekugadzira lactic acid, sekushandisa girosi yeshuga muhuni hwehuni semashanga nesawdust kugadzira lactic acid kana kuongorora nzira yekushandisa methane kugadzira lactic acid. Pakati pese, kupihwa kweiyo indasitiri yekumusoro ye polylactic acid ichave yakagadzikana mune ramangwana.
3. Midstream indasitiri
Sechinhu chakakwana che biodegradable, polylactic asidhi inogona kuunza iyo mbishi kuguma mune resource regeneration uye recycling system, iyo ine zvakanakira izvo petroleum based materials haina. Naizvozvo, kushandiswa kwepolylactic acid mumusika wepamba kuri kuwedzera. Kushandiswa kwepamba muna 2021 ndeye 48071.9 matani, kuwedzera kwe40% gore negore.
Nekuda kwekushomeka kwekugadzirwa kwepolylactic acid muChina, huwandu hwekupinzwa kunze kwepolylactic acid muChina hwakakura kupfuura huwandu hwekutengesa kunze kwenyika. Mumakore achangopfuura, huwandu hwekunze hwepolylactic acid hwakakwira nekukurumidza zvichifambiswa nekudiwa kwemba. Muna 2021, kutengwa kwepolylactic acid kwakasvika 25294.9 matani. Kutengeswa kunze kwenyika kwepolylactic acid kwakafambirawo mberi zvikuru muna 2021, kusvika pa6205.5 matani, kuwedzera kwegore negore kwe117%.
Chirevo chakabatana: Chirevo chekuvandudza maitiro ekuongorora uye kusimudzira tarisiro yekufungidzira yeChina polylactic acid chigadzirwa indasitiri kubva 2022 kusvika 2028 yakapihwa naZhiyan kubvunza.
4. Indasitiri yepasi
Mumashandisirwo ezasi, polylactic asidhi yakaiswa muminda yakawanda ine yakasarudzika biocompatibility uye biodegradability. Parizvino, yakashandiswa zvakanyanya mukudya kwekubatana level kurongedza, tableware, firimu bhegi kurongedza uye zvimwe zvigadzirwa neminda. Semuenzaniso, firimu repurasitiki rekurima rakagadzirwa nepolylactic acid rinogona kuderedzwa zvachose uye kunyangarika mushure megoho rezvirimwa, izvo zvisingazoderedze huwandu hwemvura uye kubereka kwevhu, asi zvakare kudzivirira imwe mari yebasa uye yekushanda inodiwa pakudzoreredza. firimu repurasitiki, inova maitiro akajairika ekugadzirwa kwefirimu repurasitiki muChina mune ramangwana. Nzvimbo yakafukidzwa nefirimu repurasitiki muChina inosvika 18000 mahekita, uye kushandiswa kwefirimu repurasitiki muna 2020 i1357000 matani. Pane imwe nguva yakaora firimu repurasitiki rinogona kufarirwa, iyo polylactic acid indasitiri ine nzvimbo yakakura yekusimudzira mune ramangwana.
