Itandukaniro riri hagati ya polyester ya TPU na polyether, n'isano riri hagatipolycaprolactone TPU

Ubwa mbere, itandukaniro riri hagati ya polyester ya TPU na polyether

Polyurethane ya Thermoplastic (TPU) ni ubwoko bw'ibikoresho bya elastomer bifite imikorere myiza, bikoreshwa cyane mu nzego zitandukanye. Dukurikije imiterere itandukanye y'igice cyayo cyoroshye, TPU ishobora kugabanywamo ubwoko bwa polyester n'ubwoko bwa polyether. Hari itandukaniro rinini mu mikorere n'ikoreshwa hagati y'ubwo bwoko bwombi.

Polyester TPU ifite imbaraga nyinshi kandi idapfa kwangirika, ubushobozi bwo gukurura, ubushobozi bwo kunama no kudashiramo ibintu bidafite ubushyuhe ni byiza cyane. Byongeye kandi, ifite ubushobozi bwo kudashiramo ubushyuhe bwinshi kandi irakwiriye gukoreshwa mu bushyuhe bwinshi. Ariko, ubushobozi bwo kudashiramo amazi bwa polyester TPU ni buke, kandi biroroshye kwibasirwa n’amazi no kuvunika.

Ibinyuranye n'ibyo,polyether TPUizwiho gukomera kwayo cyane, kurwanya amazi n'ubushyuhe bwayo bwinshi. Ikoranabuhanga ryayo riri hasi cyane, rikwiriye gukoreshwa ahantu hakonje. Ariko, imbaraga z'igishishwa cya polyether TPU n'ubudahangarwa bwayo ni bike cyane, kandi ubushobozi bwo gukurura no kwangirika kwa polyether TPU nabyo ni bike ugereranyije n'ubwa polyester TPU.

Icya kabiri, polycaprolactone TPU

Polycaprolactone (PCL) ni ibikoresho byihariye bya polimeri, mu gihe TPU ari mu magambo make asobanura polyurethane ya thermoplastic. Nubwo byombi ari ibikoresho bya polimeri, polycaprolactone ubwayo si TPU. Ariko, mu ikorwa rya TPU, polycaprolactone ishobora gukoreshwa nk'igice cy'ingenzi cyoroshye kugira ngo ikoreshwe na isocyanate kugira ngo ikore elastomer za TPU zifite imiterere myiza.

Icya gatatu, isano iri hagati ya polycaprolactone naTPU masterbatch

Masterbatch igira uruhare runini mu ikorwa rya TPU. Masterbatch ni prepolymer ifite imbaraga nyinshi, ubusanzwe igizwe n'ibice bitandukanye nka polymer, plasticizer, stabilizer, nibindi. Mu ikorwa rya TPU, masterbatch ishobora gukorana n'umuyoboro w'uruhererekane, igikoresho cyo guhuza, nibindi, kugira ngo ikore ibicuruzwa bya TPU bifite imiterere yihariye.

Nk'ibikoresho bya polymeri bifite imikorere myiza, polycaprolactone ikunze gukoreshwa nk'igice cy'ingenzi cya TPU masterbatch. Binyuze mu gutegura polycaprolactone hamwe n'ibindi bice, ibicuruzwa bya TPU bifite imiterere myiza ya mekanike, birwanya hydrolysis ndetse birwanya ubushyuhe buke bishobora gutegurwa. Ibi bicuruzwa bifite amahirwe menshi yo gukoreshwa mu bijyanye n'imyenda itagaragara, ibikoresho byo kwa muganga, inkweto za siporo n'ibindi.

Icya kane, imiterere n'ikoreshwa rya polycaprolactone TPU

Polycaprolactone TPU yita ku byiza bya polyester na polyether TPU, kandi ifite imiterere myiza kurushaho. Ntabwo ifite imbaraga nyinshi za mekanike no kudashira gusa, ahubwo inagaragaza ubudahangarwa bwiza bwa hydrolysis n'ubushyuhe buke. Ibi bituma polycaprolactone TPU igira ubuzima burambye kandi ihamye mu bidukikije bigoye kandi bihindagurika.

Mu bijyanye n'imyenda itagaragara, polycaprolactone TPU yabaye ibikoresho bikunzwe cyane bitewe n'imiterere yayo myiza cyane. Ishobora kurwanya kwangirika kw'ibintu byo hanze nko kugwa kw'imvura ivanze n'aside, umukungugu, amabyi y'inyoni, kandi ikarinda imikorere n'ubuzima bw'imyenda y'imodoka. Byongeye kandi, mu bijyanye n'ibikoresho by'ubuvuzi, ibikoresho bya siporo, n'ibindi, polycaprolactone TPU nayo yakunzwe cyane kubera umutekano wayo n'ubwizerwe bwayo.

Muri make, hari itandukaniro rinini hagati ya polyester ya TPU na polyether mu mikorere no mu mikoreshereze yayo, mu gihe polycaprolactone, nk'imwe mu ngingo z'ingenzi za TPU, iha ibicuruzwa bya TPU imiterere myiza cyane. Dusobanukiwe neza isano n'imiterere y'ibi bikoresho, dushobora guhitamo neza no gukoresha ibicuruzwa bya TPU bikwiye kugira ngo bihuze n'ibikenewe mu nzego zitandukanye.
