Ikoranabuhanga rya DMF yo kugarura ibiti biva mu bwoko bwa Polyurethane Synthetic uruhu rwimyanda
Abstract: Ikoranabuhanga rishya ryo kugarura DMF ryateguwe kugirango ritunganyirize N, N-dimethyl formamide (DMF) muri gaze yimyanda iva mu bwoko bwa polyurethane yubukorikori bw’uruhu.Urebye ko DMF yibanze muri gaze y’imyanda yari munsi ya 325.6-688.3 mg · m-3, byabaye ngombwa ko hajyaho ibyiciro bibiri guhuza bihagije no gushimangira ihererekanyabubasha ryiyongera aho abantu bahurira no kongera imvururu.Kubwibyo, ibyiciro bibiri byo kwinjirira hamwe na sisitemu yo gukuraho ibyiciro bibiri byinjijwe mu ikoranabuhanga.Igice cyo hejuru cyinkingi yo kwinjiza cyari cyuzuyemo insinga-ripple yubatswe idafite ibyuma bipakira BX500, mugihe igice cyo hepfo hamwe na sting-ripple ipakira CB250Y.Uburebure bwuzuye bwibikoresho byo gupakira bwari m 6.Mubyongeyeho, habaye ibyiciro bibiri byikuramo ibicu bikuraho urwego hamwe nogukwirakwiza amazi meza hejuru yinkingi hejuru.Ibipimo byose bikora, harimo ubushyuhe, umuvuduko, umuvuduko wamazi hamwe numwanya wamazi, byashoboraga kugenzurwa na mudasobwa udakoresheje intoki, ukareba ko gaze isohoka yageze ku rwego rw’igihugu ko imyuka ihumanya ikirere igomba kuba munsi ya 40 mg · m-3.Ibyo ibikoresho byose bishobora kugarura 237,6 t ya DMF buri mwaka, hamwe ninyungu igera kuri CNY 521 × 103.
