1,4 – Imarike yoRhwebo lwaMazwe ngaMazwe yeButanediol: Imfuno eNkulu, Ukuhlalisana koKhuphiswano kunye naMathuba

Kwicandelo lezorhwebo leekhemikhali kwihlabathi liphela, i-1,4 – butanediol (BDO) ivele njengemveliso ebalaseleyo kakhulu.

Idatha yakutshanje yemarike ibonisa ukuba imfuno yehlabathi ye-1,4 - butanediol iyanda ngokuthe chu. Oku kubangelwa kakhulu kukusetyenziswa kwayo ngokubanzi kumacandelo amaninzi. Kwishishini lokuvelisa iplastiki, isebenza njengezinto ezibalulekileyo zokwenza i-polyurethane elastomers, izinto ze-foam, kunye neengubo. Kwicandelo lamayeza, isetyenziswa kakhulu ekulungiseleleni amayeza kunye nezinto ezidityanisiweyo zamayeza. Kwishishini lezinto zokuthambisa, ikwadlala indima ebalulekileyo njenge-humectant kunye ne-thickener.

Ngokuphathelele idatha yokuthumela ngaphandle, ukusebenza kwe-1,4 – butanediol eTshayina kuyamangalisa kakhulu. Ukusukela ngoNovemba 20, 2024, iWuhai Customs icwangcise iibhetshi ezingama-325 zezicelo zokuhlolwa kwe-BDO, ezinomthamo weetoni ezili-147,300 kunye nexabiso leedola zaseMelika ezili-175 lezigidi, ezibonisa ukukhula konyaka nonyaka kwe-273%, 200%, kunye ne-166% ngokulandelelana. Iimveliso zithunyelwa kumazwe angama-22 nakwiindawo, kuquka uMzantsi Korea neVietnam.

Njengoko ingqwalasela yehlabathi jikelele ikhula kukhuseleko lokusingqongileyo kunye nophuhliso oluzinzileyo, amathuba ophuhliso lwe-1,4-butanediol esekelwe kwi-bio athathwa njengothembisayo kakhulu. Xa kuthelekiswa neemveliso zemveli ezisekelwe kwi-petroleum, i-BDO esekelwe kwi-bio inika izibonelelo ezinje ngobuhlobo nokusingqongileyo, izinto eziluhlaza ezihlaziyekayo, ukugcinwa kwamandla, kunye nokunciphisa ukukhutshwa komoya. Oku akupheleli nje ekuboniseni indlela entsha yophuhliso lwamashishini anxulumene nokuvelisa kodwa kukwaqinisa ngamandla umzamo wokuhlangabezana neemfuno zemarike yehlabathi zeemveliso zeekhemikhali ezinobuhlobo nokusingqongileyo.

Lilonke, imakethi yorhwebo lwangaphandle ye-1,4 - i-butanediol inamathemba abanzi. Ngelixa besebenzisa amathuba emarike, amashishini afanelekileyo kufuneka aqhubeke nokuphucula ukhuphiswano lwawo ukuze ajongane nokhuphiswano lwamazwe ngamazwe oluya lukhula ngamandla kunye neemfuno zemarike ezihlala zitshintsha.
