Itandukaniro hagati ya TPU polyester na polyether, nubusabane hagatipolycaprolactone TPU

Ubwa mbere, itandukaniro riri hagati ya TPU polyester na polyether

Thermoplastique polyurethane (TPU) ni ubwoko bwimikorere yo hejuru ya elastomer, ikoreshwa cyane mubice bitandukanye. Ukurikije imiterere itandukanye yicyiciro cyayo cyoroshye, TPU irashobora kugabanywa muburyo bwa polyester nubwoko bwa polyether. Hariho itandukaniro rinini mubikorwa no gushyira mubikorwa hagati yubwoko bubiri.

Polyester TPU ifite imbaraga nyinshi no kwambara birwanya, ibintu bitesha umutwe, kugunama no guhangana na solvent nibyiza cyane. Mubyongeyeho, ifite ubushyuhe bwiza bwo kurwanya ubushyuhe kandi burakwiriye gukoreshwa mubushyuhe bwo hejuru. Nyamara, hydrolysis irwanya polyester TPU irakennye cyane, kandi biroroshye kwibasirwa na molekile zamazi no kuvunika.

Ibinyuranye,TPUizwiho imbaraga nyinshi, kurwanya hydrolysis no kwihangana cyane. Ubushyuhe buke bwacyo nabwo ni bwiza cyane, bukwiriye gukoreshwa ahantu hakonje. Nyamara, imbaraga zishishwa nimbaraga zavunitse za polyether TPU zifite intege nke ugereranije, kandi kwihanganira, kwambara no kurira bya polyether TPU nabyo birutwa nubwa polyester TPU.

Icya kabiri, polycaprolactone TPU

Polycaprolactone (PCL) ni ibikoresho byihariye bya polymer, mugihe TPU ari ngufi kuri polyurethane ya termoplastique. Nubwo byombi ari ibikoresho bya polymer, polycaprolactone ubwayo ntabwo ari TPU. Nyamara, mubikorwa byo gukora TPU, polycaprolactone irashobora gukoreshwa nkigice cyingenzi cyoroshye cyoroshye kugirango ikore hamwe na isocyanate kugirango ikore TPU elastomers ifite ibintu byiza cyane.

Icya gatatu, isano iri hagati ya polycaprolactone naTPU

Masterbatch igira uruhare runini mugukora TPU. Masterbatch ni prepolymer yibanda cyane, mubisanzwe igizwe nibice bitandukanye nka polymer, plasitike, stabilisateur, nibindi. Mubikorwa byo gukora TPU, masterbatch irashobora kwitwara hamwe no kwagura urunigi, guhuza imiyoboro, nibindi, kugirango bitange ibicuruzwa bya TPU bifite imitungo yihariye.

Nkibikorwa byo hejuru bya polymer, polycaprolactone ikoreshwa nkigice cyingenzi cyibikoresho bya TPU. Mugihe cya prepolymerisation ya polycaprolactone hamwe nibindi bice, ibicuruzwa bya TPU bifite ibikoresho byiza bya mashini, birwanya hydrolysis hamwe nubushyuhe buke birashobora gutegurwa. Ibicuruzwa bifite ibyifuzo byinshi byo gusaba mubijyanye nimyenda itagaragara, ibikoresho byubuvuzi, inkweto za siporo nibindi.

Icya kane, ibiranga nibisabwa bya polycaprolactone TPU

Polycaprolactone TPU izirikana ibyiza bya polyester na polyether TPU, kandi ifite imitungo myiza yuzuye. Ntabwo ifite imbaraga zo gukanika gusa no kwambara, ariko kandi irerekana hydrolysis irwanya ubushyuhe buke. Ibi bituma polycaprolactone TPU igira ubuzima burebure bwa serivisi hamwe no gutuza mubidukikije bigoye kandi bihinduka.

Mu rwego rwimyenda itagaragara, polycaprolactone TPU yabaye ibikoresho byatoranijwe kubera ibintu byiza byuzuye. Irashobora kurwanya isuri yibintu byo hanze nkimvura ya aside, ivumbi, ibitonyanga byinyoni, kandi ikemeza imikorere nubuzima bwimyenda yimodoka. Byongeye kandi, mubijyanye nibikoresho byubuvuzi, ibikoresho bya siporo, nibindi, polycaprolactone TPU nayo yitabiriwe cyane kubwumutekano no kwizerwa.

Muri make, hari itandukaniro rikomeye hagati ya TPU polyester na polyether mubikorwa no kuyishyira mubikorwa, mugihe polycaprolactone, nkimwe mubice byingenzi bigize TPU, itanga ibicuruzwa bya TPU ibintu byiza byuzuye. Mugusobanukirwa byimbitse umubano nibiranga hagati yibi bikoresho, turashobora guhitamo neza no gukoresha ibicuruzwa bikwiye bya TPU kugirango duhuze ibikenewe mubice bitandukanye.
