Kugona kwekugadzira kweadipic acid munyika yangu kuri kuwedzera nekukurumidza, uye chiyero chekushanda chinoramba chiri pasi.Sezvo budiriro yenyika yangu adipic acid process ichiri kuramba ichikura uye mutengo wakanaka uchiri kuratidza zvishoma nezvishoma, nyika yangu yave mugadziri mukuru wepasi rose weadipic acid, ine huwandu hwekugadzira hunosvika 2.655 miriyoni matani muna 2019, kuwedzera kwegore negore. ye6.0%, uye mwero wekukura kwemusanganiswa unosvika makore mashanu.9.1%, nepo chiyero chekukura kwepasi rose panguva imwechete yaingova 3.9%.Muna 2019, yeChina adipic acid yekugadzira huwandu hwakaita 54% yehuwandu hwepasirese.Muna 2020, kugadzirwa kwemukati kweadipic acid kuchasvika 2.71 miriyoni matani, gore negore kuwedzera kwe2.65%, uye CAGR ichasvika 15.5% kubva 2009 kusvika 2020. mwero wekukura kwekudiwa kwakadzika, musika wepasi adipic acid wanga uchikwikwidza mumakore achangopfuura, uye huwandu hwekushandisa hwakachengetwa hunosvika makumi matanhatu muzana, uye akawanda seti emidziyo anga ari mumamiriro ekudzima kwenguva yakareba.
Makambani ekuChina ekugadzira adipic acid anonyanya kumiririrwa nemakambani makuru akadai seHuafeng Chemical, China Shenma, Haili Chemical, uye Qilu Hengsheng.Iyo CR3 muna 2020 i64.6%, uye huwandu hwekugadzira hwakanyanya kunyura.Pakati pavo, kambani inotungamira, Huafeng Chemical, ine huwandu hwe735,000 matani eadipic acid, inova yakakura kwazvo pasi rose mukukwanisa kugadzira uye ine musika wepamusha mugove unopfuura 40%.
Parizvino, China iri mutengi mukuru weadipic acid, uye mwero wekukura kwayo uri kutungamira pasirese.Muna 2019, kushandiswa kwenyika yangu kweadipic acid kwaive 1.139 miriyoni matani, gore-pa-gore kuwedzera kwe2.Huwandu hwekukura kweadipic acid inoshandiswa munyika yangu mumakore mashanu apfuura i6.8%, iyo yakakwira zvakanyanya kudarika mwero wepasi rose wekukura we3.8%.Muna 2020, kushandiswa kwepamba kweadipic acid kuchave miriyoni 1.27 matani.
Mamiriro ekushandisa mudzimba yeadipic acid munyika yangu akasiyana neaya eEurope neUnited States.Pakati pazvo, polyester polyol ndiyo yakakura pasi pemvura yekushandisa munda, iyo inonyanya kushandiswa kugadzira zvigadzirwa senge polyurethane slurry, shangu sole stock solution uye thermoplastic polyurethane elastomer.Muna 2020, huwandu hwePU slurry, sole stock solution uye PA66 mudzimba dzepasi pasi kushandiswa kweadipic acid kuchave 38.2%, 20.7% uye 17.3%, zvichiteerana.Kukurudzirwa nekukura kwekudiwa kwakadzika, kushandiswa kwepamba kweadipic acid kwakaratidza kukura kwakasimba.Pasi peplastic limit order, PBAT ine nzvimbo yakakura yekusimudzira, iyo yakapa kudiwa kukuru kweadipic acid.
