I-polypropylene eyandisiweyo (i-EPP emfutshane) yi-ultra-light, i-cell evaliweyo ye-thermoplastic foam particle esekelwe kwi-polypropylene foam.Imnyama, ipinki okanye imhlophe, kwaye ububanzi buphakathi kwe-φ2 kunye ne-7mm.Amaso e-EPP aqulunqwe ngamanqanaba amabini, aqinileyo kunye negesi.Ngokuqhelekileyo, isigaba esiqinileyo sichaza kuphela i-2% ukuya kwi-10% yesisindo esipheleleyo, kwaye enye igesi.Uluhlu oluncinci loxinaniso luyi-20-200 kg / m3.Ngokukodwa, ubunzima be-EPP bulula kunobo be-polyurethane foam phantsi kwempembelelo efanayo yokufunxa amandla.Ke ngoko, iinxalenye ze-foam ezenziwe ngamaso e-EPP zinobunzima obuncinci, zinokuchasana nobushushu obulungileyo, iipropathi ezilungileyo zokuthomalalisa kunye neempawu ezigqwesileyo zomatshini, kwaye zinokonakala nge-100% kwaye ziphinde zisebenze.Zonke ezi zibonelelo zenza i-EPP ibe yenye yezona zinto zisetyenziswa kakhulu kwiinkalo ezininzi, kuzo zonke iinkalo zobomi bethu:
Kwintsimi yeemoto, i-EPP sesona sisombululo silungileyo sokufezekisa amacandelo alula, afana ne-bumpers, i-automotive A-pillar trims, i-automotive side shock cores, i-automotive door shock cores, izihlalo eziphambili zeemoto zokhuseleko, iibhokisi zezixhobo, imithwalo, i-Armrests, i-polypropylene ene-foam. ingasetyenziselwa iindawo ezifana neepleyiti ezisezantsi, iivisor zelanga, iipaneli zesixhobo, njl.njl. Iinkcukacha-manani: Okwangoku, umyinge wexabiso leplastiki elisetyenziswa kwiimoto yi-100-130kg/isithuthi, apho isixa sesicelo sepolypropylene egwebukileyo yi-4-6kg. /isithuthi, esinokunciphisa ubunzima beemoto ukuya kuthi ga kwi-10%.
Kwintsimi yokupakisha, ukupakishwa okuphinda kusetyenziswe kunye nezikhongozeli zothutho ezenziwe nge-EPP zineempawu zokugcinwa kobushushu, ukumelana nobushushu, ukuxhathisa kwe-corrosion, i-insulation, ubomi obude benkonzo, njl. ziyingozi kwi-ozone layer okanye isinyithi esinzima Ukupakishwa kwezinto, ukugaywa emva kokufudumeza, i-100% ihambelana nokusingqongileyo.Nokuba zizinto ze-elektroniki ezichanekileyo, okanye ukuthuthwa kokutya okunje ngeziqhamo, inyama ekhenkcezisiweyo, i-ayisikrimu, njl., i-polypropylene foam eyandisiweyo ingasetyenziswa.Ngokutsho kovavanyo lwenqanaba loxinzelelo lwe-BASF, i-EPP inokufezekisa rhoqo imijikelezo yokuthunyelwa kwe-100, egcina kakhulu izinto kunye nokunciphisa iindleko zokupakisha.
Ukongeza, i-EPP inokumelana nokothuka okugqwesileyo kunye nokusebenza kokufunxa amandla, kwaye ikwasetyenziswa ngokubanzi kwimveliso yezihlalo zokhuseleko zabantwana, ithatha indawo yeplastiki enzima yemveli kunye nezixhobo zepolystyrene, kwaye iye yaba yeyona nto ikhethwayo kwiimfuno zemihla ngemihla zekhaya ezihambelana nokusingqongileyo.
Isihlalo somntwana esiphuhliswe nguKarwala ngentsebenziswano ne-KNOF Industries.Esi sesona sihlalo sikhaphukhaphu sokhuseleko lwabantwana kwimarike, sithutha abantwana kuluhlu lwe-0-13kg kunye nobunzima be-2.5kg kuphela, obungaphantsi kwama-40% kunemveliso yangoku kwimarike.
Ngaphandle koluhlu olubanzi lwezicelo, asifane silubone.Kutheni kunjalo nje?Kuba ngaphambili, umphezulu weendawo ezininzi ze-EPP ze-foam zisebenzisa i-mold kunye netekhnoloji ethe ngqo yokubumba itekhnoloji yayingeyonto intle kwaye yayihlala ifihliwe ngasemva kwezixhobo ezinjengentsimbi, isinyithi, isipontshi, igwebu, i-textile kunye nesikhumba.Kwiminyaka emininzi, kuye kwenziwa iinzame zokuphucula umgangatho womgangatho wezinto ezisemgangathweni ze-foam eziveliswayo ngokongeza ukuthungwa ngaphakathi kwezixhobo zokubumba.Ngelishwa, oku kudla ngokukhokelela kumazinga aphezulu okulahlwa.Ukubunjwa kwe-injection kuthathwa njengokwexeshana njengenkqubo efanelekileyo, kodwa iimveliso zayo azifanelekanga ngokobunzima bokukhanya, ukufunxa amandla kunye nokugquma.
Ukuze wenze umphezulu wamacandelo amagwebu amasuntswana ngcono, usenokukhetha ukusebenzisa iteknoloji laser processing emva kokuba iinxalenye zenziwe, okanye ukwenza unyango lamination ukufumana izimbo ezahlukeneyo textures.Kodwa i-post-processing ithetha kwakhona ukusetyenziswa kwamandla okongeziweyo, okuchaphazela kwakhona ukuphinda kusetyenziswe i-EPP.
Kulo mongo, i-T.Michel GmbH, kunye nezinto ezininzi eziphezulu kunye nabavelisi bezixhobo kwishishini, baqalise iteknoloji ye-"In-Mold Foamed Particle Coating" (IMPFC), etshiza ngexesha elifanayo nokubumba.Le nkqubo isebenzisa inkqubo ye-THERMO KHETHA ye-kurtz ye-Ersa, ethi ilungelelanise iindawo zobushushu zomngundo, nto leyo ekhokelela kwindawo ephezulu ekumgangatho ophezulu kunye nokushwabana okuphantsi kakhulu.Oku kuthetha ukuba iimbumba eziveliswayo zinokugqithiswa ngokukhawuleza.Oku kukwavumela ukutshiza ngaxeshanye.Ingubo yokutshiza iya kukhetha i-polymer enesakhiwo esifanayo kunye neengqungquthela ze-foam, umzekelo, i-EPP ihambelana ne-sprayed PP.Ngenxa yokudityaniswa kwesakhiwo se-single-layer, iinxalenye ze-foam eziveliswayo zi-100% zihlaziywa kwakhona.
Umpu wokutshiza we-industrial-grade osuka eNordson osasaza ipeyinti ibe yiyunifomu kunye namathontsi acolekileyo ukwenzela ukusetyenziswa okuchanekileyo kunye nokusebenza kakuhle kwiileya zangaphakathi zokungunda.Ubuninzi obukhulu bengubo bunokufikelela kwi-1.4 mm.Ukusetyenziswa kwengubo kwenza ukuba kukhethwe ngokukhululekileyo umbala kunye nokuthungwa kweendawo ezibunjiweyo, kwaye unikeze indawo enkulu yokunyuka okanye ukuguqulwa kokusebenza kwendawo.Ngokomzekelo, i-PP yokugqoka ingasetyenziselwa i-EPP foam.Izisa ukuxhathisa okulungileyo kwe-UV.
Ubunzima bokwambathisa ukuya kuthi ga kwi-1.4 mm.Xa kuthelekiswa nokubumba inaliti, itekhnoloji ye-IMPFC ivelisa iindawo ezibunjiweyo ezingaphezulu kweepesenti ezingama-60 ezikhaphukhaphu.Ngale ndlela, ukubunjwa okwenziwe ngamasuntswana amagwebu aquka i-EPP kuya kuba nethemba elibanzi.
Ngokomzekelo, iimveliso ze-EPP ze-foam aziyi kuphinda zifihlwe emva kwezinye izinto okanye zifakwe kwezinye izinto kwixesha elizayo, kodwa ziya kubonisa umtsalane wazo ngokuvulekileyo.Kwaye, kunye nemfuno ekhulayo yezithuthi zombane kwiminyaka yamuva nje kunye nendlela efanelekileyo yabathengi abatshintshela kwizithuthi zemveli ukuya kwizithuthi zombane (ngokwe-International Energy Agency, ukuthengiswa kwezithuthi zombane zehlabathi kulindeleke ukuba kufikelele kwi-125 yezigidi zeeyunithi kwi-2030. Nge-2030, i-Arhente ye-Arhente ye-Energy yamazwe ngamazwe, i-ejenti yombane wehlabathi, ukuthengiswa kwezithuthi zombane emhlabeni jikelele. I-China ilindeleke ukuba malunga ne-70% yentengiso yezithuthi iya kuba yi-EVs), eya kudala amathuba amaninzi kwimarike ye-EPP.Iimoto ziya kuba yeyona ntengiso inkulu yesicelo se-EPP.Ukongeza ekuqondeni uguqulo kunye nophuculo lwamalungu e-auto asele ekho kunye neendibano zawo, i-EPP iya kusetyenziswa kumacandelo amatsha aphuhliswe ngakumbi, kubandakanywa kodwa kungaphelelanga apho:
Kwixesha elizayo, i-EPP iya kuqhubeka idlala indima ebalulekileyo ekukhanyeni kwezinto eziphathekayo, ukufudumeza ubushushu, ukufunxa amandla, njl njl ngenxa yoluhlu olubanzi lweempawu ezintle ezingenako ukudibana nayo nayiphi na enye indibaniselwano yezinto: ixabiso eliphantsi, iimpawu ezigqwesileyo zomatshini, formability elungileyo, ubuhlobo kokusingqongileyo, njl isiphumo.
