Polyurethane ifuro ifite ibyiza byinshi kandi byingenzi. Ubwa mbere, ubushobozi bwayo bwagutse budasanzwe. Nyuma yo guterwa, ifuro ryaguka vuba inshuro 20-80 ingano yumwimerere, cyangwa ndetse hejuru. Ibi bituma yuzuza neza icyuho kidasanzwe hamwe na pore, birinda imyanda nibibazo bitaringaniye bijyana no kuzuza gakondo.
Icya kabiri, yerekana imbaraga zihuza cyane. Ifuro ya polyurethane yakize ikora ifuro rinini rikomera cyane kubintu bitandukanye nkibiti, ibyuma, na beto. Imbaraga zogosha zayo zigera kuri 0.5-1.0 MPa, zirenze kure izisanzwe. Ibi bituma iba indashyikirwa mu gushimangira imiterere.
Amashanyarazi hamwe nubushyuhe bwumuriro nibindi biranga. Ikigereranyo cyafunzwe - ingirabuzimafatizo ya furo ubusanzwe irenga 90%, ikarinda neza ubuhehere bwinjira kandi bigatuma ibera neza. Icyarimwe, ubushyuhe bwacyo buke (hafi 0.02-0.03 W / m · K), inshuro nyinshi bwibikoresho gakondo, bituma ikoreshwa cyane mukubaka ingufu.
Byongeye kandi, polyurethane ifuro nayo ifite amajwi meza. Ibikoresho byinshi bifata amajwi kandi bikagabanya kwanduza urusaku, bigatuma bikoreshwa muburyo bwo gufunga inzugi nidirishya mugushushanya urugo kugirango ubuzima bwiza bubeho. Zirwanya cyane kwangirika kwimiti, zirwanya aside, alkalis, hamwe nudukoko twangiza, bigatuma zikoreshwa mubikorwa byinganda.
Urebye ku mubiri, ibi bikoresho biroroshye, hamwe n'ubucucike bwakize bwa kg 20-50 kg / m³, butongera umutwaro wubatswe. Ifite kandi urwego rwa elastique, rushobora kwihanganira ihindagurika riterwa no kwaguka k'ubushyuhe no kugabanuka, bikagabanya ibyago byo guturika.
Mu rwego rwo kurengera ibidukikije, imiti igezweho ya polyurethane ikoresha ifumbire mvaruganda ikoreshwa cyane - ihindagurika ry’ibinyabuzima (VOC), bigabanya ihumana ry’ikirere. Amabwiriza abigenga, nka GB 18583-2008 "Imipaka y’ibintu bishobora guteza akaga mu gufatisha imitako y’imbere no kuvugurura ibikoresho," ishyiraho ibyo bicuruzwa kugira ngo ikoreshwe neza.
Icyakora, imbogamizi zigomba kandi kwitonderwa, nko kumva urumuri ultraviolet no gusaza hamwe nigihe kirekire -, bigatuma bidakwiriye ahantu hadafunguye. Muri rusange, ariko, ibyo biranga bituma polyurethane ifuro ifata ibintu byatoranijwe mubice byinshi.
