Phapang pakeng tsa polyester ea TPU le polyether, le kamano pakeng tsapolycaprolactone TPU

Taba ea pele, phapang pakeng tsa polyester ea TPU le polyether

Polyurethane ea Thermoplastic (TPU) ke mofuta oa thepa ea elastomer e sebetsang hantle, e sebelisoang haholo masimong a fapaneng. Ho ea ka sebopeho se fapaneng sa karolo ea eona e bonolo, TPU e ka aroloa ka mofuta oa polyester le mofuta oa polyether. Ho na le phapang e kholo ts'ebetsong le ts'ebelisong lipakeng tsa mefuta ena e 'meli.

Polyester TPU e na le matla a phahameng le ho hanyetsa ho tsofala, litšobotsi tsa ho tsitlella, litšobotsi tsa ho kobeha le ho hanyetsa ho qhibiliha li ntle haholo. Ho feta moo, e na le ho hanyetsa mocheso o phahameng hantle 'me e loketse ho sebelisoa libakeng tse nang le mocheso o phahameng. Leha ho le joalo, ho hanyetsa ha hydrolysis ea polyester TPU ho fokola haholo, 'me ho bonolo ho hlaseloa ke limolek'hule tsa metsi le ho robeha.

Ka papiso,polyether TPUe tsebahala ka matla a eona a phahameng, ho hanyetsa ha hydrolysis le ho mamella ho hoholo. Tshebetso ea eona ea mocheso o tlase le eona e ntle haholo, e loketse ho sebelisoa libakeng tse batang. Leha ho le joalo, matla a ho khephoha le matla a ho robeha ha polyether TPU li fokola haholo, 'me ho hanela ho teneha, ho tsofala le ho taboha ha polyether TPU le hona ho tlase ho feta ha polyester TPU.

Ea bobeli, polycaprolactone TPU

Polycaprolactone (PCL) ke thepa e khethehileng ea polymer, ha TPU e khutsufalitsoe bakeng sa polyurethane ea thermoplastic. Le hoja ka bobeli e le thepa ea polymer, polycaprolactone ka boeona ha se TPU. Leha ho le joalo, ts'ebetsong ea tlhahiso ea TPU, polycaprolactone e ka sebelisoa e le karolo ea bohlokoa ea karolo e bonolo ho arabela ka isocyanate ho hlahisa li-elastomer tsa TPU tse nang le thepa e ntle haholo.

Ea boraro, kamano pakeng tsa polycaprolactone leSehlopha se seholo sa TPU

Masterbatch e bapala karolo ea bohlokoa tlhahisong ea TPU. Masterbatch ke prepolymer e nang le mahloriso a mangata, hangata e entsoe ka likarolo tse fapaneng tse kang polymer, plasticizer, stabilizer, jj. Ts'ebetsong ea tlhahiso ea TPU, masterbatch e ka arabela ka ketane ea extender, crosslinking agent, jj., ho hlahisa lihlahisoa tsa TPU tse nang le thepa e itseng.

Jwalo ka thepa ya polymer e sebetsang hantle, polycaprolactone hangata e sebediswa e le karolo ya bohlokwa ya TPU masterbatch. Ka ho lokisa polycaprolactone ka pele ho polymerization le dikarolo tse ding, dihlahiswa tsa TPU tse nang le thepa e ntle ya mechini, kganyetso ya hydrolysis le kganyetso ya mocheso o tlase di ka lokiswa. Dihlahiswa tsena di na le menyetla e mengata ya tshebediso masimong a diaparo tse sa bonahaleng, disebediswa tsa bongaka, dieta tsa dipapadi le tse ding.

Ea bone, litšobotsi le ts'ebeliso ea polycaprolactone TPU

Polycaprolactone TPU e ela hloko melemo ea polyester le polyether TPU, 'me e na le thepa e pharaletseng haholoanyane. Ha e na matla a phahameng a mechini le khanyetso ea ho tsofala feela, empa hape e bontša khanyetso e ntle ea hydrolysis le khanyetso e tlase ea mocheso. Sena se etsa hore polycaprolactone TPU e be le bophelo bo bolelele ba ts'ebeletso le botsitso libakeng tse rarahaneng le tse fetohang.

Lefapheng la liaparo tse sa bonahaleng, polycaprolactone TPU e fetohile thepa e ratoang ka lebaka la thepa ea eona e ntle e felletseng. E ka hanela ho senyeha ha lintho tse kantle tse kang pula ea asiti, lerōle, mantle a linonyana, le ho netefatsa ts'ebetso le bophelo ba liaparo tsa koloi. Ho phaella moo, mafapheng a lisebelisoa tsa bongaka, lisebelisoa tsa lipapali, jj., polycaprolactone TPU le eona e fumane tlhokomelo e pharaletseng ka lebaka la polokeho le ts'epo ea eona.

Ka bokhutšoanyane, ho na le phapang e kholo pakeng tsa polyester ea TPU le polyether ts'ebetsong le ts'ebelisong, ha polycaprolactone, e le e 'ngoe ea likarolo tsa bohlokoa tsa TPU, e fa lihlahisoa tsa TPU thepa e phethahetseng e ntle. Ka kutloisiso e tebileng ea likamano le litšobotsi lipakeng tsa lisebelisoa tsena, re ka khetha le ho sebelisa lihlahisoa tse loketseng tsa TPU hamolemo ho fihlela litlhoko tsa masimo a fapaneng.
