ETPU Kutentha kwa Steam Moulding VS Microwave Heating Molding
ETPU, chomwe chikuyimira Expanded Thermoplastic Polyurethane Elastomer, yochokera ku BASF ku Germany mu 2007. Imapangidwa pogwiritsa ntchito TPU utomoni ngati zopangira ndikugwiritsa ntchito ukadaulo wotulutsa thovu kuti ukhale wosalumikizana TPU zinthu za thovu (ETPU). Aliyense TPU tinthu tating'onoting'ono timakula ngati ma popcorn, ndikupanga mawonekedwe a elliptical okhala ndi thovu lotsekedwa mkati, ndichifukwa chake ETPU Nthawi zambiri amatchedwa "popcorn".
ETPU imawonetsa mphamvu zolimba komanso zomangira, zomwe zimapangitsa kuti zizigwiritsidwa ntchito kwambiri popanga nsapato, ma track apulasitiki, matayala opepuka, ndi zinthu zosiyanasiyana zoteteza. Monga ntchito ya ETPU ikupitilizabe kufufuzidwa, njira zake zowumba zikukonzedwanso ndikuwongoleredwa. Kuumba kwachikhalidwe kumaphatikizapo kutentha kwa nthunzi, koma zilipo tsopano ETPU zida zomwe zilipo pamsika zoyenera kukonza ma microwave.
ETPU Njira Yopangira Nthunzi
Panopa, wamba njira ntchito msika yachiwiri thovu la ETPU ndi kutentha kwa nthunzi. Choyamba, ETPU particles ndi yodzaza mu nkhungu, ndiyeno nthunzi kutentha ntchito kuyambitsa yachiwiri thovu ndondomeko. Izi zimalola oyandikana nawo ETPU particles kuti agwirizane. Pambuyo pake, nkhunguyo imakhazikika pansi kuti amalize kuumba.
ETPU Microwave Heating Molding Njira
Njirayi imagwiritsa ntchito kutentha kwa microwave kutengera chikhalidwe cha thermoplastic ETPU. ETPU particles amayikidwa mu nkhungu ndikuyika mu uvuni wa microwave. Patapita nthawi yochepa (pafupifupi 30 masekondi), ndi ETPU tinthu tating'onoting'ono tasungunuka ndi kusakanikirana pamodzi. Chikombole chikatsegulidwa, mankhwalawa angapezeke.
Malinga ndi zomwe zilipo, mndandanda wa "MICROFLUX", wopangidwa ndi masitayelo asanu ndi limodzi, wakhazikitsidwa m'maiko monga Japan ndi United States. Monga tafotokozera patsamba lovomerezeka la Asics, mndandanda wa "MICROFLUX" umapangidwa pogwiritsa ntchito ukadaulo waposachedwa wa microwave, kulola kuti midsole iwumbe pafupifupi masekondi 30. Poyerekeza ndi kugwiritsa ntchito ukadaulo wamba wa Asics, imachepetsa kugwiritsa ntchito mphamvu pafupifupi 50%, ndikupangitsa nsapato kukhala yokhazikika.
Kufananiza Awiri ETPU Njira Zopangira
Njira Yotenthetsera
ETPU Kutentha kwa nthunzi kumaphatikizapo kuzungulira kwa nthunzi wa madzi kudzera mu nkhungu, zomwe zimapangitsa kuti kutentha kupitirire pamwamba pa ETPU particles. Ndi mawonekedwe a kutentha kudzera mu conduction kutentha kwa thupi. Kutentha kwa microwave, kumbali ina, kumagwiritsa ntchito ma radiation kuti alowe ndikuwotcha mofanana ETPU particles. Ndi mtundu wa kutentha kupyolera mu kutembenuka kwa mphamvu kudzera mu radiation.
Kusiyana kwa Ndondomeko
Popanga nthunzi, zinthuzo zimayikidwa mu nkhungu pogwiritsa ntchito mfuti yakuthupi, kenako zimatenthedwa ndi nthunzi yamadzi. Chikombolecho chimasungunuka ndi madzi ndikutsegula pang'onopang'ono.
Mu mawonekedwe a microwave, nkhungu imadzazidwa ndikutenthedwa pogwiritsa ntchito ma radiation a microwave. Ikhoza kuzirala pogwiritsa ntchito mpweya kapena njira zina, ndipo mitundu ingapo ya nkhungu imatha kutsegulidwa mosalekeza.
Poyerekeza, kuumba nthunzi kumafuna nthunzi yambiri yamadzi. Ngakhale madzi atha kubwezeretsedwanso, madzi akuwonongekabe. Kujambula kwa microwave, kumbali ina, kumangofunika kudzaza nkhungu ndikuyiyika mu microwave kuti itenthe, kuziziritsa, ndi kutsegula nkhungu. Ndiwopanda mphamvu zambiri.
Kusiyana kwa Nkhungu
Popanga nthunzi, kutentha kumayendetsedwa ndi nthunzi yamadzi. Popanga nkhungu, m'pofunika kuganizira momwe mpweya umayendera komanso zinthu zomwe zimagwiritsidwa ntchito popanga nkhungu. Izi zimayika malire pamapangidwe ndi mawonekedwe a nkhungu, ndipo zida monga aluminium yopangira thermally kapena nkhungu zamkuwa zimagwiritsidwa ntchito.
Mu microwave akamaumba, kutentha amapangidwa kudzera ma radiation kulowa. Popanga nkhungu, nkhani yokhayo yotsegula ndi kutseka kwa nkhungu iyenera kuganiziridwa, zomwe zimapangitsa kuti pakhale kusinthasintha. Zida zomwe sizimamwa ma microwave zimagwiritsidwa ntchito popanga nkhungu.
Final Product Properties
Zopangidwa pogwiritsa ntchito njira ziwirizi zimagwiritsidwa ntchito kwambiri ETPU zakuthupi, kotero mphamvu zawo zong'ambika ndi zobwereranso sizingasiyane kwambiri. Komabe, zinthu zopangidwa pogwiritsa ntchito microwave molding zitha kukhala zochulukirapo pang'ono. Kuti athane ndi vutoli, kapangidwe kazinthuzo kangapangidwe kuti achepetse kulemera, monga kuphatikiza zojambula zopanda pake mu outsole.
Kuphatikiza apo, pamapangidwe ovuta, kuumba kwa ma microwave ndikokwanira kuposa kuumba kwa nthunzi potengera mawonekedwe a nkhungu. Itha kupanga mapangidwe okhala ndi kusiyanasiyana kwakukulu mwakuya ndipo, kuphatikiza ndi malo osalala bwino, imakwaniritsa zofunikira zaufulu wazinthu za nsapato.
