n-Butane yog cov roj tsis muaj xim, flammable, thiab yooj yim liquefied gas, ib yam khoom tseem ceeb hauv roj av refining thiab natural gas processing.
Raws li ib tug roj: Nws yog siv nyob rau hauv cov dej sib zog, portable qhov cub, tsev neeg roj, thiab industrial roj.
n-Butane yog lub cev ua npuas ncauj.
Kev Txhaj Tshuaj thiab Kev Soj Ntsuam: Thaum lub sij hawm sib txuas lossis ua cov khoom siv polymers (xws li polystyrene), kua n-butane raug txhaj rau hauv cov polymer yaj hauv qhov siab. Nyob rau hauv qhov kub thiab txias, lub n-butane dissolves tag nrho nyob rau hauv lub polymer, tsim ib homogeneous sib tov.
Depressurized Foaming: Thaum qhov sib tov no extruded los ntawm los yog txhaj rau hauv pwm, lub siab sab nraud poob qis heev. Cov n-butane yaj nyob rau hauv lub polymer ua supersaturated thiab sai sai khiav tawm ntawm lub polymer, tsim ntau npuas nuclei.
Vaporization Expansion: Ib txhij, vim tias qhov ua haujlwm kub siab tshaj qhov kub ntawm n-butane (-0.5 degree), n-butane vaporizes instantaneously, nthuav dav hauv ntim (tsim kwv yees li 200 npaug ntawm nws cov ntim hauv cov pa). Qhov kev nthuav dav no ua rau cov npuas nuclei loj hlob thiab nthuav cov polymer, tsim cov qauv ua npuas ncauj.
Kho thiab Shaping: Lub polymer nws tus kheej solidifies thaum lub sij hawm txias, kho cov qauv ua npuas ncauj thiab thaum kawg yielding ib lub teeb porous ua npuas ncauj khoom.
Cim npe nrov: Highpurity 2N nbutane, Tuam Tshoj Highpurity 2N nbutane manufacturers, lwm tus neeg, Hoobkas
