Emgqeni wezohwebo lwamakhemikhali wembulunga yonke, 1,4 - I-Butanediol (BDE) ivele njengomkhiqizo omangalisayo omangalisayo.
Imininingwane yemakethe yakamuva ikhombisa ukuthi isidingo sembulunga yonke se-1,4 - i-Butanediol ibilokhu ikhula ngokuqinile. Lokhu kufakazelwe kakhulu izinhlelo zayo ezibanzi kuyo yonke imikhakha eminingi. Embonini yezondla yepulasitiki, isebenza njengento ebalulekile eluhlaza ekukhiqizweni kwama-polyurethane lastomers, izinto zokwakha amagwebu kanye nezimbobo. Emkhakheni wezemikhakha, kuvame ukusetshenziselwa ukulungiswa kwezidakamizwa kanye nemikhandlu yezemithi. Embonini yezimonyo, nayo idlala indima ebalulekile njengozithobayo nokhula.
Mayelana nedatha yokuthumela ngaphandle, ukusebenza kweChina 1,4 - Ukusebenza kwamanye amazwe weButanediol kuyamangalisa impela. Kusukela ngoNovemba 20, 2024, amasiko weWuhai acubungule ama-325 ama-batches ezicelo zokuhlola i-BDO, enomthamo wamathani angama-147,300 kanye nenani lokukhula kweminyaka engu-273%, 200%, kanye no-166% ngokulandelana. Imikhiqizo ihanjiswa kakhulu emazweni nasezifundeni ezingama-22, kufaka phakathi iSouth Korea neVietnam.
Ngokugxila okukhulayo emhlabeni jikelele ekuvikeleni kwemvelo kanye nentuthuko esimeme, amathuba okuthuthuka kwe-bio - asekelwe ku-1,4 - i-butanediol kubhekwa njengokuthembisa. Uma kuqhathaniswa nendabuko kaphethiloli - Imikhiqizo esekwe ku-BDO - I-BDO esekwe inikeza izinzuzo ezifana nobungane bezemvelo, izinto zokusetshenziswa ezivuselelekayo, ukongiwa kwamandla, nokuncishiswa kwamandla, ukuncishiswa kwamandla nokuncishiswa kwamandla. Lokhu akugcini nje kuphela indlela entsha yokuthuthuka kwamabhizinisi ahlobene nokukhiqiza kepha futhi aqede kakhulu umzamo wokuhlangabezana nesidingo semakethe yomhlaba wonke semikhiqizo yamakhemikhali enobungani bemvelo.
Sekukonke, imakethe yokuhweba yakwamanye amazwe ayi-1,4 - I-Butanediol ibamba amathuba abanzi. Ngenkathi uthatha amathuba ezimakethe, amabhizinisi afanele kumele athuthukise ngokuqhubekayo ukuncintisana kwawo ukulungisa umncintiswano wamazwe omhlaba oqhubekayo kanye naphakade - aveze izidingo zemakethe.
