Kukurumidziswa Kwekutengeserana kweBio-based BDO Kunochinja Musika weZvinhu Zvakasvibirwa zvePolyurethane zveYuan 100 Bhiriyoni

Munguva pfupi yapfuura, kufambira mberi kwetekinoroji uye kuwedzera kugona kwe1,4-butanediol (BDO) yakagadzirwa nebio-based kwave kuri kumwe kwemaitiro anozivikanwa zvikuru muindasitiri yemakemikari yepasi rose. BDO chinhu chakakosha pakugadzira polyurethane (PU) elastomers, Spandex, uye biodegradable plastic PBT, ine maitiro ayo echinyakare ekugadzira anonyanya kutsamira pamafuta efossil. Nhasi, mabhizinesi etekinoroji anomiririrwa neQore, Geno, uye Anhui Huaheng Biology yemuno ari kushandisa tekinoroji yepamusoro yebio-fermentation kugadzira BDO yakagadzirwa nebio-based yakawanda vachishandisa zvinhu zvinogona kudzokororwazve zvakaita seshuga nestarch, zvichipa kukosha kwakakosha kwekuderedza kabhoni kumaindasitiri ari pasi.

Semuenzaniso, inoshandisa mhando dzemabhakitiriya ane patent kuti ishandure shuga yemiti kuita BDO. Kana ichienzaniswa nenzira inoshandiswa nepetroleum, kabhoni yemuchigadzirwa inogona kuderedzwa kusvika 93%. Iyi tekinoroji yakawana kushanda kwakasimba kwe10,000-ton-scale muna 2023 uye yakabudirira kuwana zvibvumirano zvekutenga kwenguva refu nemakambani makuru epolyurethane muChina. Izvi zvigadzirwa zveBDO zvegirini zvinoshandiswa kugadzira Spandex neshangu dzepolyurethane dzinogara kwenguva refu, zvichizadzisa kudiwa kukuru kwezvinhu zvisina njodzi kubva kumabhizinesi ekupedzisira akadai seNike neAdidas.

Panyaya yekuchinja kwemusika, BDO ine chekuita nemakemikari haingori nzira yekuwedzera chete asiwo kusimudzira zvakatipoteredza kwecheni yemaindasitiri echinyakare. Zvichienderana nenhamba dzisina kukwana, huwandu hweBDO ine chekuita nemakemikari echinyakare hwakaziviswa pasi rose uye huri kusagadzirwa hwapfuura matani 500,000 pagore. Kunyangwe mutengo wayo wepari zvino wakakwira zvishoma pane wezvigadzirwa zvemafuta, zvichitungamirirwa nemitemo yakaita seEU's Carbon Border Adjustment Mechanism (CBAM), mutengo wepamusoro wemafuta echinyakare uri kugamuchirwa nevaridzi vemhando dzakawanda. Zvinotarisirwa kuti nekuburitswa kwesimba remagetsi kunotevera kwemakambani akawanda, BDO ine chekuita nemakemikari echinyakare ichachinja zvakanyanya maitiro ekugadzira zvinhu zve polyurethane nefiber zvemachira e100 bhiriyoni mumakore matatu anotevera, zvichitsigirwa nekuenderera mberi kwekugadzirisa kukwikwidzana kwayo nemitengo.
