Ukusetshenziswa Komshini Wokufutha Igwebu Ensimini Yokushisisa Okushisayo
Ukufafaza nge-polyurethane kusho inqubo yokusebenzisa imishini yobuchwepheshe, ukuhlanganisa i-isocyanate ne-polyether (evame ukwaziwa ngokuthi izinto ezimnyama nezimhlophe) ne-ejenti ekhihliza amagwebu, i-catalyst, i-flame retardant, njll., ngokufafaza ngengcindezi ephezulu ukuze kuqedelwe inqubo yokwenza amagwebu e-polyurethane esizeni.Kufanele...Funda kabanzi -
Kuyini ukusetshenziswa kwe-elastomer?
Ngokwendlela yokubumba, ama-polyurethane elastomers ahlukaniswe abe yi-TPU, CPU kanye ne-MPU.I-CPU iphinde ihlukaniswe yaba yi-TDI(MOCA) ne-MDI.Ama-elastomer e-polyurethane asetshenziswa kabanzi embonini yemishini, embonini yezimoto, embonini ye-petroleum, embonini yezimayini, kagesi kanye nezinsimbi ...Funda kabanzi -
Kuyini ukusetshenziswa kwegwebu eliguquguqukayo kanye ne-Integral Skin Foam (ISF)?
Ngokusekelwe ezicini ze-PU Foam eguquguqukayo, igwebu le-PU lisetshenziswa kabanzi kuzo zonke izigaba zokuphila.I-polyurethane foam ihlukaniswe izingxenye ezimbili: i-rebound ephezulu kanye ne-rebound ehamba kancane.Ukusetshenziswa kwayo okuyinhloko kufaka phakathi: umcamelo wefenisha, umatilasi, umcamelo wemoto, imikhiqizo eyinhlanganisela yendwangu, izinto zokupakisha, umsindo...Funda kabanzi -
yini ukusetshenziswa kwegwebu eliqinile le-polyurethane?
Njengoba i-polyurethane i-foam eqinile (i-PU rigid foam) inezici zesisindo esilula, umphumela omuhle wokushisa oshisayo, ukwakhiwa okulula, njll., futhi inezici ezinhle kakhulu ezifana nokufaka umsindo, ukumelana nokushaqeka, ukufakwa kukagesi, ukumelana nokushisa, ukumelana nokubanda, i-solvent kabusha...Funda kabanzi -
Ubuchwepheshe obusha bokwenza ukulingisa kwe-ceramic nge-scrap polyurethane material
Esinye isicelo esimangalisayo se-polyurethane foam!Okubonayo ukwenza kusuka ku-low rebound kanye ne-high resilience material scrap material.lokhu kuzosebenzisa kabusha udoti ngo-100%, futhi kuthuthukise ukusebenza kahle nezinga lokubuya kwezomnotho.Ihluke ngokulingisa izinkuni, lokhu kulingisa kwe-ceramic kuzoba ne-st...Funda kabanzi
