Polystyrene imwe yemapurasitiki anoshandiswa zvakanyanya.Yakawedzerwa polystyrene, thermoplastic, inonyunguduka kana yapiswa uye inoshanduka yakasimba kana yatonhodzwa.Iyo ine yakanakisa uye inogara yekupisa yekupisa, yakasarudzika cushioning uye kushomeka kuramba, anti-kuchembera uye kudzivirira mvura, saka yakashandiswa zvakanyanya munzvimbo dzakasiyana siyana dzakadai sekuvaka, kurongedza, zvigadzirwa zvemagetsi nemagetsi, ngarava, mota nekugadzira ndege, zvekushongedza zvinhu, uye kuvaka dzimba.kushandiswa zvakanyanya.Zvinopfuura 50% zvadzo ndezvemagetsi nemagetsi kuvhundutsa-absorbing packaging, mabhokisi ehove uye zvigadzirwa zvekurima uye kumwe kutsva-kuchengeta kurongedza, izvo zvinofambisa hupenyu hwedu zvakanyanya.
EPS kugadzirwa kwemhepo - nzira huru muindasitiri
Kazhinji EPS yekuumba maitiro inosanganisira anotevera matanho akakosha: pre-foaming → kurapa → kuumba.Pre-flashing ndeyekuisa mabedhi eEPS mudhiramu remuchina wepre-flashing, wopisa nemhepo kusvika yapfava.Iyo inopupa (kazhinji 4-7% pentane) yakachengetwa muEPS bead inotanga kufashaira uye kunyungudika.Iyo yakashandurwa pentane gasi inowedzera kudzvinyirira mukati meEPS mabhesi, zvichiita kuti vawedzere muhuwandu.Mukati meiyo inobvumidzwa yekumhanyisa furo, iyo inodiwa yekupupa chiyero kana chechikamu giremu huremu hunogona kuwanikwa nekugadzirisa pre-yekuwedzera tembiricha, dzvinyiriro yemutsinga, huwandu hwekudya, nezvimwe.
Iwo achangobva kuumbwa furo particles akapfava uye anelastic nekuda kwekuvhuvhuta kweiyo furo agent uye condensation yeasara foam agent, uye mukati mune vacuum state uye yakapfava uye inelastic.Naizvozvo, panofanira kunge paine nguva yakakwana yekuti mweya upinde mumamicropores mukati me furo particles kuti ienzanise nemukati nekunze kumanikidza.Panguva imwecheteyo, inobvumira iyo yakasungirirwa furo particles kuti iparadze hunyoro uye kubvisa iyo static magetsi yakangounganidzwa nekukweshera kwe furo particles.Iyi nzira inonzi kurapa, iyo inowanzotora maawa 4-6.Mabheji akatambanudzwa uye akaomeswa anotamirwa kune mold, uye steam inowedzerwa zvakare kuti mabheji abatane, obva atonhodzwa uye akaumbwa kuti awane chigadzirwa chine furo.
Inogona kuwanikwa kubva pamaitiro ari pamusoro apa kuti steam chinhu chakakosha chekupisa simba reEPS bead foam molding.Asi kupisa kwehutsi uye kutonhora kweshongwe yemvura zvakare ndiyo inonyanya kukosha kushandiswa kwesimba uye kabhoni emission link mukugadzira.Pane imwezve simba inoshanda kune imwe nzira yekusanganiswa kwefuro rechidimbu pasina kushandisa chiutsi?
Electromagnetic wave radio frequency melting, Kurt Esa Group (inozonzi "Kurt") yekuGermany yakapa mhinduro yavo.
Iyi shanduko yekutsvagisa uye tekinoroji yekuvandudza inosiyana neyechinyakare chiutsi maitiro, ayo anoshandisa masaisai eredhiyo kupisa.Radio wave heat inzira yekudziya inotsamira pachinhu kutora simba reradio wave nekurishandura kuita simba rekupisa, zvekuti muviri wese unopisa panguva imwe chete.Nheyo yekuziva kwayo ndiyo dielectric alternating field.Kuburikidza neiyo yakakwirira-frequency inodzokorodza mafambiro ea dipole mamorekuru mukati memuviri unopisa, "mukati mekuputika kupisa" kunogadzirwa kuwedzera tembiricha yezvinhu zvinopisa.Pasina chero kupisa conduction process, mukati uye kunze kwezvinhu zvinogona kupisa.Kupisa panguva imwe chete uye kupisa panguva imwe chete, kukurumidza kupisa kunokurumidza uye yunifomu, uye chinangwa chekupisa chinogona kuwanikwa chete nechikamu kana chegumi chekushandiswa kwesimba kwechinyakare kupisa nzira.Nokudaro, iyi inovhiringidza maitiro inonyanya kukodzera kugadzirisa mabheji akawedzerwa ane polar molecular structures.Kurapa kwezvinhu zvisiri-polar zvinosanganisira mabheji eEPS, zvinongodiwa chete kushandisa zvidimbu zvakakodzera.
Kazhinji, mapolymers anogona kupatsanurwa kuita polar polima uye asiri-polar mapolymer, asi iyi nzira yekuisa muchikamu ndeye yakajairika uye haisi nyore kutsanangura.Parizvino, polyolefins (polyethylene, polystyrene, nezvimwewo) inonyanya kunzi non-polar polymers, uye mapolymer ane mapoka epolar mucheni yepadivi anonzi polar polymers.Kazhinji, inogona kutongwa maererano nemhando yemapoka anoshanda ari papolymer, akadai semapolymer ane amide mapoka, nitrile mapoka, ester mapoka, halogens, nezvimwewo ari polar, nepo polyethylene, polypropylene uye polystyrene Hapana mapoka epolar. pane equimolecular chain, saka iyo polymer hainawo polar.
Kureva kuti, iyo yekugadzira nzira ye electromagnetic wave radio frequency kunyunguduka inongoda magetsi nemhepo, uye haidi kuisa dhizaini kana bheseni remvura inotonhorera shongwe mudziyo, uri nyore uye uri nyore, uye unochengetedza simba uye unochengetedza nharaunda. .Kuenzaniswa nemaitiro ekugadzira uchishandisa steam, inogona kuchengetedza 90% yesimba.Nekubvisa kukosha kwekushandisa chiutsi nemvura, kushandisa Kurtz WAVE FOAMER kunogona kuchengetedza 4 miriyoni marita emvura pagore, izvo zvakaenzana nekunwa kwepagore kwemvura kwevashoma ve6,000 vanhu.
Pamusoro pekuchengetedza simba uye kuchengetedza kwezvakatipoteredza, electromagnetic wave radio frequency kunyunguduka inogona zvakare kugadzira emhando yepamusoro furo zvigadzirwa.Iko chete kushandiswa kwemafungu emagetsi mune frequency renji kunogona kuve nechokwadi chekunyungudika uye kuumbwa kwemafuro zvimedu.Kazhinji, izvo zvinodikanwa zvekugadzikana kwevhavhavha yehutsi zvakakwirira kwazvo uchishandisa tsika yechinyakare, zvikasadaro zvinokonzeresa kuti chigadzirwa chideredze uye chive chidiki pane saizi yakafanotemerwa mushure mekutonhora.Yakasiyana nekuumbwa kweutsi, shrinkage rate yezvigadzirwa zvinogadzirwa ne electromagnetic wave radio frequency melting molding inodzikiswa zvakanyanya, kugadzikana kwedimensional kunovandudzwa zvakanyanya, uye kunyura kwefuro particles uye kusara kwehunyoro uye furo jena muforoma inokonzeresa dzakaderedzwa zvikuru.Vhidhiyo, ngationei pamwe chete!
Pamusoro pezvo, tekinoroji yekunyungudutsa yeredhiyo inovandudza zvakanyanya mwero wekudzoreredza wefoamed particle zvinhu.Kazhinji, kudzokororwa kwezvigadzirwa zvefuro kunoitwa nemakanika kana makemikari.Pakati pavo, iyo mechanical recycling nzira ndeyekucheka zvakananga uye kunyungudutsa epurasitiki, uye wozoishandisa kugadzirira yakaderera-mhando yakadzokororwa zvinhu, uye zvinhu zvenyama zvinowanzove zvakaderera kune yekutanga polymer (Mufananidzo 1).Iwo mamorekuru madiki anowanikwa anobva ashandiswa sezvishandiso kugadzira furo nyowani.Kuenzaniswa nemaitiro emagetsi, kugadzikana kwezvikamu zvitsva zvefuro kunovandudzwa, asi nzira yacho ine simba guru rekushandisa uye yakaderera kupora.
Tichitora polyethylene plastiki semuenzaniso, kupisa kwekuparara kwechinhu ichi kunoda kuva pamusoro pe600 ° C, uye chiyero chekudzorera ethylene monomer isingasviki 10%.Iyo EPS inogadzirwa neyechinyakare dhizaini inogona kudzokorodza kusvika makumi maviri muzana yezvinhu, nepo EPS inogadzirwa neredhiyo frequency fusion tekinoroji ine mwero wekudzokorodza we70%, unonyatsoenderana nepfungwa ye "stainable development".
Parizvino chirongwa chaKurt "Chemical-Free Recycling yeEPS Materials neRadio Frequency Fusion Technology" chahwina mubairo we2020 weBavarian Energy.Makore maviri ega ega, Bavaria inopa mubairo kune vakabudirira zvikuru muchikamu chesimba, uye Bavarian Energy Prize yave imwe yemibairo yepamusoro muchikamu chesimba.Panyaya iyi, Rainer Kurtz, CEO weKurtz Ersa, akati: "Kubva payakavambwa muna 1971, Kurtz yakaramba ichitungamira kusimudzira indasitiri yekugadzira foam, uye yakaramba ichigadzira nzira dzakasimba dzekubatsira mukugadzirwa kwakasimba munyika. .Mupiro.Parizvino, Kurtz akagadzira akasiyana siyana eindasitiri-inotungamira tekinoroji.Pakati pavo, iyo Kurtz WAVE FOAMER - radio wave foam molding process tekinoroji, iyo isingango chengetedza simba uye ine hushamwari kwezvakatipoteredza, asi zvakare inogona kuburitsa yemhando yepamusoro furo, yakachinja zvachose Kugadzirwa kwechinyakare furo zvigadzirwa, kugadzira remangwana rakasvibirira. kuitira kuti furo rigadzirike”.
Parizvino, Kurt's radio wave foam molding tekinoroji yatanga kugadzira akawanda-kugadzira EPS furo zvigadzirwa.Mune ramangwana, Kurt anoronga kushandisa tekinoroji iyi kune zvinoshatisa zvinhu uye EPP zvinhu.Mumugwagwa webudiriro inoenderera, isu tichaenda mberi uye mberi nevatengi vedu.
