ETPU Steam Heating Molding VS Microwave Heating Molding
ETPU, izvo zvinomirira Expanded Thermoplastic Polyurethane Elastomer, yakabva kuBASF kuGermany muna 2007. Inogadzirwa nekushandisa TPU resin seyakagadzirwa uye kushandisa tekinoroji yekupupa kwemuviri kugadzira isina-crosslinked TPU furo bead zvinhu (ETPU). Imwe neimwe TPU chidimbu chinowedzera sepopcorn, ichigadzira elliptical maumbirwo ane micro-akavharwa mabhuru mukati, ndosaka ETPU inowanzonzi "popcorn".
ETPU inoratidza kusimba kwakanakisa uye kumisa zvivakwa, zvichiita kuti ishandiswe zvakanyanya mushangu, maturu epurasitiki, matai asina kuremerwa, uye zvakasiyana zvigadzirwa zvekudzivirira. Sekushandiswa kwe ETPU inoramba ichiongororwa, maitiro ayo ekuumba ari kuvandudzwa uye kuvandudzwa. Iyo yechinyakare yekuumba maitiro inosanganisira kupisa kwemhepo, asi iko zvino ETPU zvinhu zvinowanikwa mumusika zvakakodzera microwave processing.
ETPU Steam Heating Molding process
Parizvino, iyo yakajairika nzira inoshandiswa mumusika kune yechipiri furo ye ETPU ari steam kupisa molding. Chekutanga, ETPU zvimedu zvinotakurwa muforoma, uye ipapo kupisa kwemhepo kunoiswa kuti kukonzeresa kuburitsa furo. Izvi zvinobvumira iyo yakatarisana ETPU zvimedu kuti zvisanganise pamwechete. Mushure mezvo, mold inotonhodzwa pasi kuti ipedze kuumba.
ETPU Microwave Heating Molding process
Iyi nzira inoshandisa microwave kudziyisa zvichibva pane thermoplastic chimiro che ETPU. ETPU zvidimbu zvinotakurwa muforoma uye zvinoiswa mukati memicrowave oven. Mushure menguva pfupi yenguva (inenge 30 masekondi), iyo ETPU zvidimbu zvinonyungudutswa zvishoma uye zvinosanganiswa pamwechete. Kana mold yavhurwa, chigadzirwa chinogona kuwanikwa.
Maererano neruzivo rwuripo, nhevedzano ye“MICROFLUX”, ine masitayera matanhatu akasiyana, yakatangwa munyika dzakadai seJapan neUnited States. Sezvakataurwa pawebhusaiti yepamutemo yeAsics, iyo "MICROFLUX" yakatevedzana inogadzirwa uchishandisa ichangoburwa microwave molding tekinoroji, zvichibvumira kuti midsole iumbwe mukati memasekondi makumi matatu. Kana ichienzaniswa nekushandiswa kweAsics 'yakajairwa tekinoroji, inoderedza kushandiswa kwesimba nechikamu chinosvika 30%, zvichiita kuti ive sarudzo inogadzika yeshangu.
Kuenzanisa kweVaviri ETPU Molding Maitiro
Kuchenesa Method
ETPU Kupisa kwemhepo kunosanganisira kutenderedza mhute yemvura kuburikidza neforoma, zvichiita kuti kupisa kuitwe pamusoro pemvura. ETPU zvimedu. Icho chimiro chekudziya kuburikidza nekuita kupisa kwemuviri. Microwave heat, kune rumwe rutivi, inoshandisa mwaranzi kupinda uye nekupisa zvakaenzana ETPU zvimedu. Iyo imhando yekudziya kuburikidza nekushandura simba kuburikidza nemwaranzi.
Maitiro Akasiyana
Mukuumbwa kweutsi, zvinhu zvinopinzwa muforoma uchishandisa pfuti yezvinhu, zvobva zvapiswa nemhute yemvura. Iyo mold inotonhodzwa nemvura uye yakavhurwa nguva nenguva.
Mune microwave molding, mold inozadzwa uye yobva yapiswa uchishandisa microwave radiation. Inogona kutonhodzwa uchishandisa mhepo kana dzimwe nzira, uye akawanda seti ezviumbwa anogona kuvhurwa nguva dzose.
Mukufananidza, kuumbwa kwemhepo kunoda huwandu hukuru hwemhute yemvura. Kunyange kana mvura ichigona kushandiswazve, pachine kuraswa kwezviwanikwa zvemvura. Microwave molding, kune rumwe rutivi, inongoda kuzadza mold uye kuiisa mu microwave yekudziya, kutonhora, uye kuvhura mold. Inonyanya kushandisa simba.
Mold Kusiyana
Mukuumbwa kweutsi, kupisa kunoitwa kuburikidza nemhute yemvura. Paunenge uchigadzira mold, kutariswa kunoda kupihwa kune kutungamira kwemhepo inoyerera uye zvinhu zvinoshandiswa kugadzira mold. Izvi zvinoisa zvimwe zvipimo pachimiro uye chitarisiko che mold, uye zvinhu zvakaita se thermally conductive aluminium kana mhangura molds zvinowanzo shandiswa.
Mu microwave molding, kupisa kunogadzirwa kuburikidza nemwaranzi yekupinda. Paunenge uchigadzira mold, chete nyaya yekuvhura uye kuvhara mold inoda kutariswa, ichibvumira kuwedzera dhizaini kuchinjika. Zvishandiso zvisingatore ma microwaves zvinoshandiswa kuumba.
Final Product Properties
Zvigadzirwa zvinogadzirwa uchishandisa ese ari maviri maitiro anonyanya kushandiswa ETPU zvinhu, saka simba ravo rekubvarura uye rebound zvivakwa hazvizosiyane zvakanyanya. Nekudaro, zvigadzirwa zvinogadzirwa uchishandisa microwave molding zvinogona kunge zvine density yakakwira zvishoma. Kuti ugadzirise nyaya iyi, chimiro chechigadzirwa chinogona kugadzirwa kuderedza uremu, sekubatanidza magadzirirwo asina kusimba mune outsole.
Uyezve, kune dzakaoma dhizaini, microwave molding inokwanisa kupfuura kuumbwa kweupfu mukudzokorodza chimiro chepamusoro che mold. Inogona kugadzira dhizaini neyakasiyana-siyana mukudzika uye, yakasanganiswa nenzvimbo yakatsetseka, inosangana zviri nani nedhizaini yerusununguko zvinodiwa zvezvigadzirwa zveshangu.
