I-Polystyrene yenye yeeplastiki ezisetyenziswa kakhulu.I-polystyrene eyandisiweyo, i-thermoplastic, iyanyibilika xa ishushu kwaye ijike iqine xa ipholile.Ine-insulation ye-thermal egqwesileyo kwaye ihlala ihlala njalo, i-cushioning ekhethekileyo kunye nokumelana nokothuka, ukulwa nokuguga kunye nokungangeni kwamanzi, ngoko isetyenziswe ngokubanzi kwiinkalo ezahlukeneyo ezifana nokwakhiwa, ukupakishwa, iimveliso zombane kunye ne-elektroniki, iinqanawa, izithuthi kunye nokuveliswa kweenqwelomoya, izixhobo zokuhombisa, kunye nokwakhiwa kwezindlu.esetyenziswa ngokubanzi.Ngaphezulu kwe-50% yazo yi-electronic ne-electric shock-absorbing packaging, iibhokisi zeentlanzi kunye neemveliso zezolimo kunye nezinye iipakethe ezisanda kugcinwa, ezilungiselela kakhulu ubomi bethu.
Ukwenziwa komphunga kwe-EPS – inkqubo eqhelekileyo kushishino
Ngokuqhelekileyo inkqubo yokubumba ye-EPS ibandakanya la manyathelo aphambili alandelayo: ukukhupha ugwebu kwangaphambili → ukunyanga → ukubumba.Ukukhanya kwangaphambili kukubeka amaso e-EPS kumbhobho womatshini odanyazayo wangaphambili, kwaye uwufudumeze ngomphunga de ithambe.I-agent ye-foaming (ngokuqhelekileyo i-4-7% pentane) egcinwe kwi-EPS beads iqala ukubilisa kunye nokunyuka.I-pentane gas eguqulwayo yandisa uxinzelelo ngaphakathi kweebhondi ze-EPS, ezibangela ukuba zandise umthamo.Ngaphakathi kwesantya esivumelekileyo se-foaming, umlinganiselo ofunekayo we-foaming okanye i-particle gram ubunzima inokufumaneka ngokulungelelanisa ubushushu bokwandiswa kwangaphambili, uxinzelelo lwe-steam, inani lokutya, njl.
Iincinci ze-foam ezisandul 'ukubunjwa zithambile kwaye zinelastic ngenxa ye-volatilization ye-agent ye-foaming kunye ne-condensation ye-agent e-foam eseleyo, kwaye ingaphakathi likwimeko ye-vacuum kwaye ithambile kwaye inelastic.Ngoko ke, kufuneka kubekho ixesha elaneleyo lokuba umoya ungene kwi-micropores ngaphakathi kweengqungquthela ze-foam ukulungelelanisa uxinzelelo lwangaphakathi nangaphandle.Ngelo xesha, ivumela iinqununu ze-foam eziqhotyoshelweyo ukuba zichithe umswakama kwaye ziphelise umbane osisigxina oqokelelwe ngokwemvelo ngokuxutywa kweengqungquthela ze-foam.Le nkqubo ibizwa ngokuba kukunyanga, okuthatha malunga neeyure ezi-4-6.Ubuhlalu obandisiweyo obungaphambili kunye nobomileyo badluliselwa kwi-mold, kwaye i-steam yongezwa kwakhona ukwenza ubuhlalu bubambene, kwaye bupholile kwaye budilizwe ukufumana imveliso enegwebu.
Inokufunyanwa kule nkqubo ingentla ukuba umphunga ngumthombo wamandla obushushu oyimfuneko ekubunjweni kwebead ye-EPS.Kodwa ukufudumeza komphunga kunye nokupholisa kwinqaba yamanzi nakona kusetyenziswa kwamandla abalulekileyo kunye namakhonkco okukhutshwa kwekhabhoni kwinkqubo yokuvelisa.Ngaba kukho enye inkqubo eyonga amandla ngakumbi yokudityaniswa kwegwebu lesuntswana ngaphandle kokusetyenziswa komphunga?
I-Electromagnetic wave radio frequency melting, iKurt Esa Group (emva koku ebizwa ngokuba yi "Kurt") yaseJamani inike impendulo yayo.
Olu tshintsho lophando kunye nophuhliso lobuchwephesha lwahlukile kwinkqubo yomphunga yemveli, esebenzisa amaza erediyo ukufudumeza.Ukufudumeza kwamaza erediyo yindlela yokufudumeza exhomekeke kwinto ukuba ifunxe amaza erediyo amandla ize iwaguqule abe ngamandla obushushu, ukuze umzimba ufudumale wonke ngaxeshanye.Isiseko sokuqonda kwayo yintsimi ye-dielectric alternating.Ngokusebenzisa i-high-frequency reciprocating motion ye-dipole molecules ngaphakathi komzimba oshushu, "ukushisa kwangaphakathi kwe-friction" kuveliswa ukwandisa ubushushu bezinto ezifudumalayo.Ngaphandle kwenkqubo yokuqhuba ukushisa, ngaphakathi nangaphandle kwezinto eziphathekayo kunokufudumeza.Ukufudumeza ngexesha elifanayo kunye nokufudumeza kwangaxeshanye, isantya sokufudumeza sikhawuleza kwaye siyafana, kunye nenjongo yokufudumala inokufezekiswa kuphela ngeqhezu okanye inxalenye yeshumi yokusetyenziswa kwamandla kwindlela yokufudumala yendabuko.Ngoko ke, le nkqubo yokuphazamiseka ifaneleka ngokukodwa ekuqhubeni amaso awandisiweyo kunye nezakhiwo ze-polar molecular.Ukunyangwa kwezinto ezingezizo ze-polar ezibandakanya ubuhlalu be-EPS, kuyimfuneko kuphela ukusebenzisa izongezo ezifanelekileyo.
Ngokubanzi, iipolymers zinokwahlulwa zibe ziipolymers zepolar kunye neepolymers ezingezizo ipolar, kodwa le ndlela yokuhlela ibanzi kwaye akukho lula ukuyichaza.Okwangoku, iipolyolefins (i-polyethylene, i-polystyrene, njl.) zibizwa ngokuba ziipolymers ezingekho phantsi, kwaye iipolymers eziqukethe amaqela e-polar kwikhonkco elisecaleni zibizwa ngokuba yi-polar polymers.Ngokuqhelekileyo, inokugwetywa ngokohlobo lwamaqela asebenzayo kwi-polymer, njengama-polymers anamaqela e-amide, amaqela e-nitrile, amaqela e-ester, i-halogens, njl. kwikhonkco ye-equimolecular, ngoko ke i-polymer ayikho polar.
Oko kukuthi, inkqubo yokwenza i-electromagnetic wave radio frequency melting ifuna kuphela umbane nomoya, kwaye ayifuni kufakela inkqubo yomphunga okanye isixhobo sokupholisa isitya samanzi, esilula kwaye sifanelekile, kwaye sigcina amandla kwaye sikhusela okusingqongileyo. .Xa kuthelekiswa nenkqubo yokuvelisa usebenzisa umphunga, inokonga i-90% yamandla.Ngokuphelisa isidingo sokusebenzisa i-steam kunye namanzi, ukusebenzisa i-Kurtz WAVE FOAMER inokugcina i-4 yezigidi zeelitha zamanzi ngonyaka, okulingana nokusetyenziswa kwamanzi ngonyaka ubuncinane be-6,000 abantu.
Ukongeza kugcino lwamandla kunye nokukhuselwa kokusingqongileyo, i-electromagnetic wave radio frequency melting inokuvelisa iimveliso zogwebu ezikumgangatho ophezulu.Kuphela kukusetyenziswa kwamaza ombane kuluhlu lwamaza anokuqinisekisa okona kunyibilika kunye nokwenza amasuntswana amagwebu.Ngokuqhelekileyo, iimfuno zokuzinza kwe-valve ye-steam ziphezulu kakhulu usebenzisa inkqubo ye-steam yendabuko, ngaphandle koko iya kubangela ukuba imveliso iyancipha kwaye ibe yincinci kunobungakanani obunqunywe kwangaphambili emva kokupholisa.Ngokwahlukileyo ekubunjweni komphunga, inqanaba lokucutheka kweemveliso eziveliswe yi-electromagnetic wave radio frequency melting molding iyancitshiswa kakhulu, uzinzo lwedimensional luphuculwe kakhulu, kunye nokufunxwa komphunga wamasuntswana amagwebu kunye nokufuma okushiyekileyo kunye nearhente enogwebu kubumba obubangelwa kukujiya. zincitshiswe kakhulu.Ividiyo, masiyive kunye!
Ukongeza, itekhnoloji yokunyibilikisa kanomathotholo iphucula kakhulu isantya sokubuyiselwa kwezinto zamasuntswana amagwebu.Ngokuqhelekileyo, ukurisayikilishwa kweemveliso zogwebu kwenziwa ngoomatshini okanye ngokwekhemikhali.Phakathi kwabo, indlela yokuphinda isetyenziswe kumatshini kukunqunqa ngokuthe ngqo kunye nokunyibilikisa iplastiki, kwaye emva koko uyisebenzise ukulungiselela izinto ezisemgangathweni ezihlaziyiweyo, kwaye izinto eziphathekayo zihlala zingaphantsi kwepolymer yokuqala (Umfanekiso 1).Iimolekyuli ezincinci ezifunyenweyo ziye zisetyenziswe njengezinto ezisetyenziswayo ukulungisa amasuntswana amagwebu amatsha.Xa kuthelekiswa nendlela yomatshini, ukuzinza kwamaqhekeza amatsha amagwebu kuphuculwe, kodwa inkqubo inokusetyenziswa kwamandla aphezulu kunye nezinga eliphantsi lokubuyisela.
Ukuthatha iplastiki ye-polyethylene njengomzekelo, ubushushu bokubola kwesi sixhobo kufuneka sibe ngaphezu kwe-600 ° C, kwaye izinga lokubuyisela i-ethylene monomer lingaphantsi kwe-10%.I-EPS eveliswe yinkqubo yesiqhelo yomphunga inokuphinda isetyenziswe ukuya kuthi ga kwi-20% yezinto, ngelixa i-EPS eveliswe yitekhnoloji ye-radio frequency fusion inezinga lokuphinda lisetyenziswe kwi-70%, ehambelana ngokugqibeleleyo nombono "wophuhliso oluzinzileyo".
Ngoku iprojekthi kaKurt “Ukwenziwa ngokutsha kwaMahala kweChemical-Free Recycling ye-EPS Materials yiRadio Frequency Fusion Technology” iphumelele ibhaso laMandla eBavaria lowama-2020.Rhoqo kwiminyaka emibini, ibhaso laseBavaria liwonga abaphumeleleyo abagqwesileyo kwicandelo lamandla, kwaye iBhaso le-Bavarian Energy libe lelinye lawona mabhaso aphezulu kwicandelo lamandla.Kulo mba, uRainer Kurtz, i-CEO ye-Kurtz Ersa, uthe: "Ukususela ekusekweni kwayo ngo-1971, uKurtz uye waqhubeka ekhokela uphuhliso lweshishini lokubumba i-foam, kwaye uye waqhubeka nokuphuhlisa iinkqubo ezizinzileyo zokufaka isandla kwimveliso ezinzileyo kwihlabathi. .Igalelo.Ukuza kuthi ga ngoku, uKurtz uphuhlise iintlobo ngeentlobo zetekhnoloji ekhokelayo kwishishini elinelungelo elilodwa lomenzi wechiza.Phakathi kwabo, i-Kurtz WAVE FOAMER - itekhnoloji yenkqubo ye-radio foam yokubumba, engagcini nje ukusindisa amandla kunye nokusingqongileyo, kodwa inokuvelisa amagwebu akumgangatho ophezulu, itshintshe ngokupheleleyo iMveliso yeemveliso zamagwebu emveli, idala ikamva eliluhlaza. ukusetyenzwa kogwebu okuzinzileyo”.
Okwangoku, itekhnoloji yokubumba igwebu likanomathotholo kaKurt sele iqalisile ukuvelisa ngobuninzi iimveliso ze-EPS zogwebu.Kwixesha elizayo, uKurt uceba ukusebenzisa le teknoloji kwizinto ezichithwayo kunye nezixhobo ze-EPP.Kwindlela yophuhliso oluzinzileyo, siya kuhambela phambili kunye nabathengi bethu.
