Imboni yakwaHyundai Motor Company i-Ulsan izosebenzisa ngokukhethekile inhlanganisela yegwebu le-BASF ye-Elastoflex polyurethane ukwenza izihlalo zemoto.Leli gwebu le-polyurethane elinwebeka kakhulu linokuqukethwe okuphansi kwe-VOC futhi lisetshenziswa kakhulu ekukhiqizeni izihlalo zemoto namakhanda.Uma kuqhathaniswa namagwebu endabuko,I-Elastoflex ithuthukisa ukunethezeka, ukunwebeka kanye nezakhiwo ezithwala umthwalo wezihlalo namakhanda.Ukuze kuhlangatshezwane nemithethonqubo eqinile yokulawula ukungcoliswa komoya, i-BASF iphinde yathuthukisa inqubo yokukhiqiza ama-polyether polyols.Ama-polyether polyols asetshenziswa ekukhiqizeni i-Elastoflex polyurethane foam, esetshenziswa ekukhiqizeniizihlalo zokunethezeka okuphezulu.Inqubo yokukhiqiza eyenziwe kahle yenza i-BASF ikhiqize ama-polyether polyols akhethekile anezindleko eziphansi, ukusebenza okuphezulu kanye nokukhishwa kwe-VOC okuphansi.Ezivivinyweni ezenziwa yisikhungo sokuhlola esihamba phambili emhlabeni i-SGSKorea, i-Elastoflex yehlise ukukhishwa kwe-acetaldehyde ne-formaldehyde ngaphezu kuka-30%, isiza ukuthuthukisa ikhwalithi yomoya wemoto nempilo yabashayeli bezimoto.Ukuhlolwa kwensimu kuphinde kwabonisa ukuthi ukwakheka kwe-polyurethane okusanda kuthuthukiswa kunezindawo ezinhle kakhulu zokugeleza kanye nenani elincishisiwe lesici somkhiqizo, okuholela ekukhiqizeni okuthuthukisiwe komugqa wokukhiqiza.
Izinto ezintsha zinezinzuzo ezinamandla.Ekukhiqizeni izimoto, izihlalo zemoto zihlala endaweni enkulu, enquma ngokuqondile inani lezinto ezisetshenziswayo.Izimoto zithinta kancane kancane indlela yokuphila yabantu futhi zenza uhambo lwabantu lube lula nakakhulu.Izihlalo zezimoto zendabuko ngokuvamile ziyimikhiqizo yesikhumba, futhi eziningi zazo zenziwe ngesipontshi nezinye izinto, ezingenakho izinga elithile lokunethezeka.Namuhla, amapulasitiki e-polyurethane foam aguquguqukayo Njengenye yezinto zokukhiqiza izihlalo zemoto, ikhwalithi ephezulu kanye nenani eliphansi, futhi kancane kancane isetshenziswa abakhiqizi enanini elikhulu lokukhiqiza imoto.“I-Polyurethane Foam iwuhlobo lwento entsha ethambile enokunwebeka okuthile.Inezimbotshana eziningi, i-density sole, iyakwazi ukumelana nokuqina, ukumuncwa komsindo, ukuphefumula, ukufakwa kahle kwe-thermal kanye nezinye izakhiwo.Isetshenziswa kuzo zonke izici zokuphila.Abakhiqizi abaningi bakhetha i-High-elastic polyurethane foam isetshenziswa njengempahla yezihlalo zemoto, futhi ukusebenza kwalolu lwazi kuyamukelwa kancane kancane abantu.
Iinduduzo ye-static yeisihlalo semotoibhekisela ekutheni ubudlelwano obufanayo phakathi kwesihlalo semoto nomzimba womuntu bunganikeza abasebenzisi izimo zokuhlala ezinethezekile.Ukunethezeka kwesihlalo kuhlobene nemingcele yesayizi, ukwelashwa kwendawo kanye nezici zokulungiswa kwesihlalo.Ukwakheka kwesihlalo kuyingxenye ye-foam ene-elasticity ephezulu kanye nokuminyana okuphansi, okungavimba ukuthi izinto zingashi.Namuhla, uhulumeni wase-China unezidingo eziqinile ezintweni zezimoto, ezidinga inani eliphezulu lokuvutha libe ngu-≤70mm/min.Imithetho enjalo yandisa kakhulu ukuphepha kwemoto ngokwayo, futhi i-polyurethane foam eguquguqukayo enalesi silinganiso sokushisa isetshenziswa.Ukwenza ama-saddles nakho kubonakala kancane kancane emkhakheni wombono wabakhiqizi.Ukumelana nokugqokwa kwegwebu le-polyurethane eliguquguqukayo kusetshenziswa njengempahla eluhlaza yezihlalo zemoto.I-fragility yemikhiqizo eminingi yepulasitiki yenza kube nzima ukuyisebenzisa isikhathi eside, kodwa i-polyurethane foam eguquguqukayo inokumelana okuhle kokugqoka.Inamandla okuqineka okuqinile kanye nokumelana nezinyembezi, okwenza kube nokusebenza okuphezulu.Uma kuqhathaniswa nezihlalo zezimoto zendabuko, izindleko zayo ziphansi, isikhathi sokusebenzisa side, futhi ipulasitiki yayo iqinile.ithandwa ngabakhiqizi.
Ukuthuthukiswa kwemboni ye-polyurethane foam akunakuhlukaniswa nokuthuthukiswa kwamandla okukhiqiza.Njengenye yezinto eziyisithupha ezinkulu zokwenziwa emhlabeni eziheha ukunaka kakhulu, izinga lemboni yegwebu le-polyurethane liye landa ngokushesha eminyakeni yamuva.Ngokusho kwe- "2016-2022 China Polyurethane Industry Market Trend Forecast and Trend Forecast Research Report" ekhishwe yi-Booz Data: ukukhiqizwa komhlaba wonke kwemikhiqizo ye-polyurethane kudlule amathani ayizigidi ezingu-21, lapho uhlelo lwegwebu kanye nemikhiqizo yesistimu engeyona igwebu i-akhawunti ngayinye iyingxenye. yezwe, futhi amandla ayo amakhulu okukhula alungiselelwa ukunakwa.Ukuthambekela kwesikali sokukhiqiza kusobala Emkhiqizweni, imboni ye-polyurethane, njengezimboni eziningi zamakhemikhali, inomkhuba osobala okhulayo wokuqina kanye nesikali.Njengoba ubuchwepheshe bokukhiqiza i-polyurethane bukhula ngokukhula, imikhiqizo iya idume kakhulu futhi izinkundla zokufaka izicelo ziqhubeka nokwanda, abakhiqizi bathole ukuthi ukuze balondoloze izinga elithile lenzuzo, kufanele babe neminotho ethile yesikali.Ngenxa yalokho, isilinganiso amabhizinisi amasha aya ngokuya eba mkhulu, namandla okukhiqiza nawo akhula ngokushesha.Ukwamukelwa kwabathengi akukacaci, futhi kunemininingwane eminingi okufanele ithuthukiswe.Njengoba kushiwo ngenhla, i-polyurethane foam ephezulu-elastic uhlobo olusha lwezinto ezibonakalayo, futhi abantu abakabi nokuqonda okujulile kwezici zayo, ngakho-ke akukaze kube khona ukuqwashisa okukhulu kwemakethe okwamanje.Ngenxa yokuthi imoto ihlobene kakhulu nempilo yabantu ngemuva kokuthengwa, futhi ngenxa yentengo yayo ephezulu, imindeni eminingi ngeke ishintshe imoto isikhathi eside ngemuva kokuyithenga.Ukuhlola izakhiwo zayo ezihlukahlukene, isihlalo esenziwe ngegwebu le-polyurethane eliguquguqukayo kancane kancane siye saba ngenye yezinto abantu abagxile kuzo.
Uma kuqhathaniswa nezihlalo zendabuko, izihlalo ezenziwe ngegwebu le-polyurethane elisha eliguquguqukayo zinokungaqiniseki okuningi.Ngakho-ke, akukabi yinto okufanele ibe nayo emiqondweni yabathengi.Okokuqala, ukusabela kwamakhemikhali kwe "polyurethane foam" ngokwayo.Ngemuva kokuthi igwebu le-polyurethane eliguquguqukayo lenziwe esihlalweni semoto, ngenxa yokuchayeka elangeni isikhathi eside, ukungangeni komoya kwemoto kuphezulu, futhi izinga lokushisa ngaphakathi emotweni lizoba phezulu kakhulu.Ukusabela nokukhishwa kwegesi enobuthi kuzobeka engcupheni ukuphepha kwempilo yabashayeli.Ngokwemiphumela yocwaningo olufanele, inani elikhulu le-siloxane lizongena emikhiqizweni eminingi yemoto eqediwe ngesikhathi sokukhiqizwa, futhi izingxenye zayo azikwazi ukukhiqiza ngokuqondile izinto ezinobuthi, kodwa ngesikhathi senqubo ethile yokushintshashintsha, i-siloxane izosakazeka kancane kancane ibe yigwebu le-polyurethane eliguquguqukayo. isihlalo semoto, sithuthukise ukuntengantenga kwegwebu le-polyurethane eliguquguqukayo, futhi kukhiqize amagesi anobuthi.Ngakho-ke, kuyadingeka ukuthuthukisa le nto ngenkuthalo futhi unciphise umsebenzi wayo.Ngaphezu kwalokho, ngokwezidingo ze-ergonomic, isihlalo semoto sidinga ukuklanywa njengomkhiqizo onobuso obuthile obugobile, okunzima ukukufeza ngenxa yebhokisi-uhlobo lwegwebu. inqubo "polyurethane Foam".Ngakho-ke, inqubo yokubumba kuphela igwebu engasetshenziswa njengamanje., ngokwezinga elithile ivimbela ukuthuthukiswa “kwegwebu le-polyurethane elinwebekayo eliphakeme”.Njengoba sonke sazi, ehlobo, ilanga likhanya ngqo ngaphakathi emotweni.Ngenxa yokubekwa uphawu okungcono kwemoto, kuzodala izinga lokushisa eliphezulu emotweni.Uma igwebu linobuthi, izinga lokushisa eliphezulu kanye nokungangeni komoya ngaphakathi emotweni kuzodala ushevu kubantu abasemotweni.Ngasikhathi sinye, uma igwebu liqukethe inani elikhulu lezinto eziphilayo, uma lincibilika futhi lishintshashintsha ekushiseni okuphezulu, inani elikhulu lezinto eziphilayo lizoguquguquka phezu kwengilazi yemoto, okuzothinta kakhulu umbono womshayeli kanye nembangela. izingozi zomgwaqo.Ngakho-ke, ukuqonda okuphelele kokusebenza kwalolu hlobo lwe-foam kuyadingeka , Kungale ndlela kuphela le nto ingasetshenziswa kangcono, kancane kancane yamukelwe abashayeli futhi yamukelwe ngabathengi abaningi.Ngokombono wokuqwashisa kwabathengi kanye nemfundo kanye nokuphawula okungekuhle, kusenendlela ende okufanele ihanjwe ngaphambi kokuthi i-polyurethane foam ephezulu ibe yindinganiso yezihlalo zemoto zesikhathi esizayo.
Kodwa ngokuhamba kwesikhathi, nakuba i-elastic polyurethane foam ngokwayo ineziphambeko ezithile, izinzuzo zayo zibaluleke kakhulu.Ngikholelwa ukuthi esikhathini esizayo esiseduze, ngokuthuthuka kwezinga labantu lesayensi nezobuchwepheshe, ukushiyeka kwegwebu le-polyurethane eliguquguqukayo kuzodlula lapho, ubuchwepheshe bokukhiqiza izimoto kanye nesici sokuphepha kwemoto kuye kwathuthukiswa nakakhulu.Kungaleso sikhathi kuphela lapho lapho igwebu le-polyurethane eliqinile liyoba nethuba lokuba indinganiso ezihlalweni zemoto ezizayo.
