Aliphatic TPU rarolla bothata ba bosehla ba ETPU lieta
ETPU ke mofuta oa TPU Boitsebiso e entsoeng ka ho phophoma ka ho feteletseng. Hobane ponahalo ea eona e tšoana le popcorn, midsole e entsoeng ka ETPU e bitsoa popcorn midsole. E na le mamello e ntle haholo, khatello e tlase haholo ea deformation e sa feleng, boiphihlelo bo botle ba ho apara, le ts'ebetso e ntle ea tikoloho le e sebetsang hantle.
Adidas ke mofuta oa pele oa lipapali ho sebelisa popcorn midsole, 'me lieta tsa eona tsa Boost Series li kile tsa tsebahala' marakeng. Ka lebaka la ts'ebetso e babatsehang ea ETPU midsole, lihlahisoa tse ngata tsa lipapali li e amohetse ka lieta tsa lipapali.
Leha ho le joalo, ha nako e ntse e ea, batho ba fumane hore bosoeu ETPU midsole e tla fetoha mosehla ka mor'a ho apara nako e telele, 'me ke mofuta o ke keng oa hloekisoa, o amang phihlelo ea ho apara ho isa tekanyong e itseng.
Hobaneng ha ETPU midsole e fetoha mosehla ka mor'a ho apara nako e telele? Sena se amana le sebopeho sa limolek'hule tsa TPU.
TPU ke khutsufatso ea thermoplastic polyurethanes, e leng multiphase block copolymer e entsoeng ka diisocyanate, chain extender, le polyol. Ho itšetlehile ka mofuta oa disocyanate, TPU e arotsoe haholo ka monko o monate TPU le aliphatic TPU, 'me phapang ea tshebetso pakeng tsa tse peli e tsepamisitsoe haholo-holo ho hanyetsa ho mosehla.
- Karolo e tloaelehileng ea monko o monate TPUTlhaloso: Diphenylmethane disocyanate (MDI)
- Karolo e tloaelehileng ea aliphatic TPU Hexamethylene diisocyanate (HDI)
Boholo ba TPU e sebelisoang bophelong ba letsatsi le letsatsi e monko o monate TPU, e atisang ho ba mosehla ka lebaka la sebopeho sa lesale la benzene ho MDI, joalokaha ho bontšitsoe setšoantšong se ka tlase.
MDI e na le borokho ba methylene pakeng tsa lihlopha tse peli tsa phenyl, 'me methylene ena e na le oxidized habonolo tikolohong ea leseli la ultraviolet, kahoo e lahleheloa ke hydrogen borokho ba methylene, joalokaha ho bontšitsoe setšoantšong se ka tlase.
Karabelo ena ea lik'hemik'hale e theha tsamaiso e kopaneng pakeng tsa mehele e 'meli e nkhang hamonate, e bitsoang quinoid imine. Le hoja karabelo ena ea oxidation e na le phello e fokolang ho thepa ea 'mele ea TPU, e ka etsa hore e ke keng ea etsolloa mosehla oa TPU.
Ho tloha ka ETPU e lokisoa ka ho phophoma ka monko o monate o tloaelehileng TPU, mosehla ke ntho e ke keng ea qojoa. Joang ho rarolla bothata bona? Ho sebelisa aliphatic TPU ke tsela e ntle.
Aliphatic TPU, e tsejoang hape ka hore ke e sa nkhang hamonate TPU, joalo ka ha ho bonts'itsoe setšoantšong se ka tlase, e na le sebopeho sa mela ea molek'hule ea diisocyanate ester. Ha ho bapisoa le monko o monate TPU, ho hanyetsa ha eona ho mosehla ho ntlafala haholo.
Aliphatic TPU e na le mefuta e mengata ea ho thatafala, le joalo ka e tloaelehileng TPU, ho nka 40D le 45D e le mehlala, ka mor'a ho foamisa, li lumellana le li-midsoles tsa 45C le 50C, ka ho latellana, tse nang le litšoaneleho tse kang boima bo tlaase, elasticity e ntle, ho hanyetsa ka mokhoa o babatsehang ho mosehla, le ho thibela ho lla ho babatsehang.
