Hauv kev lag luam tshuaj lom neeg thoob ntiaj teb, 1,4-butanediol (BDO) tau tshwm sim ua cov khoom lag luam zoo heev.
Cov ntaub ntawv lag luam tsis ntev los no qhia tau hais tias qhov kev thov thoob ntiaj teb rau 1,4 - butanediol tau nce ntxiv tas li. Qhov no feem ntau yog vim nws cov ntawv thov dav dav thoob plaws ntau qhov chaw. Hauv kev lag luam tsim khoom yas, nws ua haujlwm ua cov khoom siv tseem ceeb rau kev tsim cov polyurethane elastomers, cov ntaub ntawv ua npuas ncauj, thiab cov txheej txheem. Hauv kev lag luam tshuaj, nws feem ntau siv rau hauv kev npaj cov tshuaj thiab cov tshuaj nruab nrab. Hauv kev lag luam tshuaj pleev ib ce, nws kuj ua lub luag haujlwm tseem ceeb ua tus neeg ua kom noo thiab ua kom tuab.
Hais txog cov ntaub ntawv xa tawm, Tuam Tshoj txoj kev xa tawm 1,4 - butanediol yog qhov zoo kawg nkaus. Txij li thaum Lub Kaum Ib Hlis 20, 2024, Wuhai Customs tau ua tiav 325 pawg ntawm BDO kev tshuaj xyuas daim ntawv thov, nrog rau qhov ntim ntawm 147,300 tons thiab tus nqi ntawm 175 lab daus las Asmeskas, sau npe xyoo - rau - xyoo kev loj hlob ntawm 273%, 200%, thiab 166% feem.

Nrog rau kev tsom mus rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov thoob ntiaj teb, kev cia siab rau kev txhim kho ntawm bio-based 1,4-butanediol tau suav tias yog qhov zoo. Piv rau cov khoom siv roj av ib txwm muaj, bio-based BDO muaj cov txiaj ntsig xws li kev phooj ywg ib puag ncig, cov khoom siv raw rov ua dua tshiab, kev txuag hluav taws xob, thiab kev txo qis pa phem. Qhov no tsis yog tsuas yog qhia txog txoj hauv kev tshiab rau cov tuam txhab tsim khoom cuam tshuam tab sis kuj txhawb nqa kev siv zog los ua kom tau raws li kev thov thoob ntiaj teb rau cov khoom siv tshuaj lom neeg ib puag ncig.
Zuag qhia tag nrho, kev lag luam txawv teb chaws ntawm 1,4 - butanediol muaj kev cia siab dav. Thaum nrhiav kev lag luam, cov tuam txhab lag luam yuav tsum txhim kho lawv qhov kev sib tw kom daws tau qhov kev sib tw thoob ntiaj teb thiab kev xav tau ntawm kev lag luam uas hloov pauv tas li.
