Iimateriali zesiPU ezincedisiweyo zibe ngokubanzi nobungakho obuchaphazekileyo okulula lokuhlola iindlela ezininzi. Iindawo ezikhona ziqukethwe kwiifurniture, toys, kunye nomphumela weemashini. Ngoku kwenziwa ngeendawo ezininzi ezidingekayo, iirigid PU zizibekelwa ngemibono eminingi. Lomkhonto wabo ukuba abe ngazo kufuneka kwindawo ezininzi apho kuhlanganiswa umthombo wesithuthu nokubhukuda. Nangoko, uma ungene uchweba elungileyo, ungaba yinto yokugqibela iirigid PU ezincediseyo ukuba zityipha inani leenkxaso engapheleleyo ngaphandle kokucabanga. Le ndawo kwenziwa ukuba yayingxoxo elulunga lokuhlala kwisezantsi ipolyurethane ende
PU Engelezi ingavumelekanga kakhulu—uyisinga ngazo kwiimbali eminingi izicatshulwa . Baza babenziwa ngemibono ezininzi, okwangoku sithetha ukuthi siyazisebenzisa ngazo ukuthatha amagumbi, amathophu, kunye nomahluko wezintaba. Ngokugcina lokho, umdlalo wenkxaso nothengisi zizama ukuhlela izinto ezincedwayo kodwa ezindala nokuthi zihlabeleka. Ngenxa yoko, imigumbi nemikhanda yokubheka kunye neentsha yokusebenza zazidinga amaxwebhu aphantsi lwePU ngqo ukuba bazingeni phakathi komkhankho wesithathu. Zazihamba ukusuka kumahluko kunye nokungena ngeentsha nokuhlala ngaphandle kwamanye amagumbi. Ukuthi amato, amashoes kunye namasithelo somphakathi sokusebenza zazidinga amaxwebhu aphantsi lwePU ngqo, ngakwesobunxele abaningi kwiimibi esiyaziyo esisetyenziswa ngaso kulesi sizini.
Yeyiphi okuyazi kakhulu okugcina i-PU elibhokisi ngakumbi lokuba kukho amandla angaphezulu ukusebenza ngeye ngokuqinisekileyo. Isiqephu sasendle esingabangako kubantu kunye neziphumo eziningi zokusetyenziswa nayo xa ungenisa izinto. Isiqephu sasendle sesivumela ukuba yintoni nesigxelo esisindane, umthombo omkhulu . Amathombo ase-PU asizange azitye ingxenyeni, ngoba kuhluke kunye nokuba akukho into engenziwe ngayo ukusetyenziswa kunye nokuphazamiswa, ngakwethu amaxwebhu alunyuzwa kunye nokuba akufunekayo ukuba akutshabalalise kuze akusuke. Kungapheli inxalenye yokuba umoya wokushayelela kunye nokusetshenziswa kwento, ukuqonda ukuba kufuneka kuhluke kunye nokuba kuhluke kakhulu. Ngokulandelana, i-PU elibhokisi yayinga lula kumoya, uyahlala ngokukhona ukuthi kwenzeleyo kuhlola kunye nokuthatha ngokuphephileyo kwindawo yokugcina. Ukuthi le nto iyahlala ngokukhona kunye nokuthi kungafani kunye nokuba kuhluke kunye nokuba kuhluke kakhulu. Ukusetyenziswa kweziqhaza kunye nokuthi kuhluke kunye nokuba kuhluke kakhulu — Amathombo ase-PU ahlala ngokukhona kunye nokuthi akukho umoya wokushayelela kunye nokuthi akukho amacala. Lento yayifuna ukuba kuhluke kunye nokuba kuhluke kakhulu kwiinkcukacha ezidingekayo zokusetshenziswa.
Kukho izinto ezininzi ezibangel' umdla eziye zaphuhliswa kwiminyaka edlulileyo kwiteknoloji ye-PU engqindilili eyenza ezi zinto zibe ngcono nangakumbi. Uhlaziyo olubalulekileyo kukwandiswa kwezinto ezongezelelweyo ezinokuxutywa ne-PU engqongqo. Ezi zinto zongeziweyo zenza ukuba izinto zomelele kwaye zihlale ixesha elide, ngoko ke ziya kuba luncedo kwimveliso evela kuzo. Enye into entsha ebalulekileyo ziindlela ezintsha zokuvelisa. Ezi nkqubo enkosi kwezi teknoloji zintsha, zifudumeza kwaye zithambe kancinci, zinceda ukubumba ezo zinto ziqinileyo zePU ngendlela echanekileyo, zisinika imveliso esemgangathweni ongcono. Ezi phuculo zenze i-PU engqongqo ibe lula ngakumbi kwaye isebenziseke kwizicelo ezahlukeneyo ukusuka kwiimveliso zokusetyenziswa kwemihla ngemihla ukuya koomatshini abakhethekileyo.
Jikela kwiqhagamshelwe zonke izithetho sezikhundleni esizenza ukuthola amandla apha ngokubheka ukusukumisa kwesihlanu sasehlulekile, ukufumana izimvo eziqhutywa ngenxa yamatirha lePU elibhokisiwe kuyinto engaphambili okunyeleyo. Iimatirha lePU elibhokisiwe zinakwazi ukuphucula nokuba zingasetyenziswa, lokhu kukho ofanele lokuhlala phambi kokuthi zisetyenziswa ngendlela eyona yokuba zisetyenziswa, ngoko ke zinakwazi ukusetshenziswa ukwenza isimo esiqhutywayo esingayiphiwe ngaphandle kokusetshenziswa ngemuva kokusetyenziswa. Iimatirha lePU elibhokisiwe zinakwazi ukusebenzisa umoya omndeni. Ukwenza amanxoxo kunye neziqephu ezilungileyo ngokusetshenziswa nokuphucula kweematirha lePU elibhokisiwe ukuthi ziyinhlangano engekho ukuthi zisetshenziswa ngemuva kokusetshenziswa. Uya kuthola imibono emfaneleyo ngeamatirha lePU elibhokisiwe kunye neziqephu ezifaneleyo ukusetshenziswa nokuphucula kweematirha lePU elibhokisiwe ukuthola ukulandelana nokushintsha ukudibanisa ukuthi usetyenziswa ngemuva kokusetshenziswa. Isimo esethembekayo sasingafuna ukuthi siyisebenzise.
