Iphaneli yesangweji ye-polyurethane Iphaneli yesamishi lephahla
Iphaneli yophahla lwe-polyurethane yenziwe ngezingqimba ezi-2 zamashidi ensimbi anombala angamelana nesimo sezulu futhi yafaka izinhlobo eziqinile ze-polyurethane phakathi kwezingqimba ezi-2 ezifaka izinto ezingashi.Ihlukaniswe yaba izinhlobo ezimbili: Amagagasi amathathu ephaneli yophahla oluyinhlanganisela ye-polyurethane, Amagagasi amane ephaneli yophahla eyinhlanganisela ye-polyurethane.Izinhlamvu zephaneli ye-PU yi-heat insulation, i-waterproof, i-soundproof, futhi kulula ukuyifaka.Umsebenzi omuhle kakhulu yisizathu sokuthi abantu abaningi bayikhetha njengebhodi lophahla.
