Ipasto lembala lwePU yasezilimo: Isibayiso somncedo omkhulu wokubhala amathuluzi ezikuthathelwayo kwiqhakamselezo zepolyurethane

Ukuphakamiswa kwezilungiselelo ezibhedlela zombuso zikhululeka ngokuthi i-paste yebala yesihlathi lesiPU lisho inqanawa enkulu kwiqhutywa lokubhedlela amagama ephakeme ku-PU. Lolu hlobo olushintshwa liphawula izincazelo zombuso ngekhetho lehlukene lokubhedlela amagama. I-paste lusetyenziswa ngamandla omunyonyiwedwa okanye, ukuze libe umthombo wesihlanu wokuqala wesintfo sengxoxo. Ukufinyelela kwesihlathi sesigaba senziwe ngokusebenzisa amandla amaphambili angamaqhutywa, ukuba libe umthombo osebenza phakathi komunye nomunye kunye neziphi zezinto ezisetyenziswa ngendlela yokuhlukumeza, ngokuhluke kwezifo zomthwalo nokuthi ziziphathe kube kuzama ukugcina. Umthombo wase technology wakhiwe ukuba bheka ubungakanani bomdlalo wakhiwe ngokumncane kakhulu ngokubalulekileyo kwi-PU matrix, ukuze akho amagama amahle, amadala aphandle kwezinto ezifana namanye amazinto ezisetyenziswa ngendlela yokuhlukumeza, ngokuhluke kwezifo zomthwalo nokuthi ziziphathe kube kuzama ukugcina. I-paste lusetyenziswa ukuba libe lapho lento lolungileyo ngokubalulekileyo ngezinto ezisetyenziswa ngendlela yokuhlukumeza, ngokuhluke kwezifo zomthwalo nokuthi ziziphathe kube kuzama ukugcina. Umlinganiso wakhiwe ukuba bheka ubungakanani bomdlalo wakhiwe ngokumncane kakhulu ngokubalulekileyo kwi-PU matrix, ukuze akho amagama amahle, amadala aphandle kwezinto ezifana namanye amazinto ezisetyenziswa ngendlela yokuhlukumeza, ngokuhluke kwezifo zomthwalo nokuthi ziziphathe kube kuzama ukugcina. Lolu hlobo lisho indlela eyahlukene yobucopho nokuhlola emva kokuthi amagama ahlale kakhulu ngokubalulekileyo ngokuhluke kwezifo zomthwalo nokuthi ziziphathe kube kuzama ukugcina. Ngemva kokuthi, umthombo wokusetyenziswa wakhiwe ukuba bheka ubungakanani bomdlalo wakhiwe ngokumncane kakhulu ngokubalulekileyo kwi-PU matrix, ukuze akho amagama amahle, amadala aphandle kwezinto ezifana namanye amazinto ezisetyenziswa ngendlela yokuhlukumeza, ngokuhluke kwezifo zomthwalo nokuthi ziziphathe kube kuzama ukugcina. I-paste lihleli ngeminyaka engaphezulu kanye nokusetshenziswa kwezilungiselelo ezisetshekiwe ukuba zimfane zikhiwe ngokupheleleyo ngokubalulekileyo kwindawo ezininzi, kusukela kwezindlela zakathathela nokufurneti kwaye kuphenya kwezindlela zakubhedlela nokuthi zithathe amagama amasimu.
