Endaweni yokuhweba ngamakhemikhali emhlabeni wonke, i-1,4 – butanediol (BDO) ivele njengomkhiqizo ovelele kakhulu.
Idatha yemakethe yakamuva ikhombisa ukuthi isidingo somhlaba wonke se-1,4 - butanediol besilokhu sikhula njalo. Lokhu kubangelwa kakhulu ukusetshenziswa kwayo kabanzi emikhakheni eminingi. Embonini yokukhiqiza ipulasitiki, isebenza njengezinto zokusetshenziswa ezibalulekile ekukhiqizweni kwama-polyurethane elastomers, izinto ze-foam, kanye nezingubo. Embonini yezokwelapha, ivame ukusetshenziswa ekulungiseleleni izidakamizwa kanye nezidakamizwa ezisetshenziswayo. Embonini yezimonyo, idlala indima ebalulekile njenge-humectant kanye ne-thickener.
Ngokuphathelene nedatha yokuthumela kwamanye amazwe, ukusebenza kwe-China yokuthumela kwamanye amazwe i-butanediol engu-1,4 kuyamangalisa impela. Kusukela ngoNovemba 20, 2024, i-Wuhai Customs isicubungule amaqoqo angu-325 ezicelo zokuhlola i-BDO, enomthamo wamathani angu-147,300 kanye nenani lamadola aseMelika ayizigidi ezingu-175, okubhalise amazinga okukhula konyaka nonyaka angu-273%, 200%, kanye no-166% ngokulandelana. Imikhiqizo ithunyelwa ikakhulukazi emazweni nasezifundeni ezingu-22, okuhlanganisa iNingizimu Korea neVietnam.
Njengoba kugxilwe kakhulu emhlabeni wonke ekuvikelweni kwemvelo kanye nentuthuko esimeme, amathuba okuthuthukiswa kwe-bio-based 1,4-butanediol abhekwa kabanzi ethembisayo. Uma kuqhathaniswa nemikhiqizo yendabuko esekelwe kuphethiloli, i-bio-based BDO inikeza izinzuzo ezifana nobungane bemvelo, izinto zokusetshenziswa ezivuselelekayo, ukongiwa kwamandla, kanye nokunciphisa ukukhishwa kwegesi. Lokhu akugcini nje ngokuhlela indlela entsha yentuthuko yamabhizinisi okukhiqiza ahlobene kodwa futhi kuqinisa kakhulu umzamo wokuhlangabezana nesidingo semakethe yomhlaba wonke semikhiqizo yamakhemikhali enobungane nemvelo.
Sekukonke, imakethe yokuhweba yangaphandle engu-1,4 - i-butanediol inamathemba abanzi. Ngenkathi bebamba amathuba emakethe, amabhizinisi afanele kumele aqhubeke nokuthuthukisa ukuncintisana kwawo ukuze abhekane nokuncintisana kwamazwe ngamazwe okuqhubeka nokuba namandla kanye nezidingo zemakethe ezihlala zishintsha.
Isikhathi sokuthunyelwe: Jan-23-2025
