Ukukhishwa kwe-TPU (i-Thermoplastic Polyurethane)

1. Ukulungiselela Izinto Ezibalulekile

• I-TPUUkukhetha Ama-Pellets: KhethaAma-pellet e-TPUngobunzima obufanele (ubulukhuni bogu, ngokuvamile obusukela ku-50A kuya ku-90D), inkomba yokugeleza kokuncibilika (i-MFI), kanye nezici zokusebenza (isb., ukumelana nokuguguleka okuphezulu, ukuqina, kanye nokumelana namakhemikhali) ngokwezidingo zomkhiqizo wokugcina.
• Ukomisa:I-TPUi-hygroscopic, ngakho-ke kumele yomiswe ngaphambi kokukhipha ukuze kususwe umswakama. Umswakama ungabangela amabhamuza, ukukhubazeka kobuso, kanye nokwehla kwezakhiwo zemishini emikhiqizweni ekhishwe. Ukomisa kuvame ukwenziwa ekushiseni okuphakathi kuka-80 - 100°C amahora angu-3 - 6.

2. Inqubo Yokukhipha

• Izingxenye Zokukhipha Izinto
  • Umgqomo: Umgqomo womshini wokukhipha ushiswa ezindaweni eziningi ukuze uncibilikise kancane kancane ama-pellet e-TPU. Iphrofayili yokushisa isethwe ngokucophelela ukuqinisekisa ukuthi kuncibilika kahle ngaphandle kokushisa ngokweqile - okungabangela ukuwohloka. Isibonelo, izinga lokushisa lendawo yokudla lingaba cishe ngu-160 - 180°C, indawo yokucindezela cishe ngu-180 - 200°C, kanye nendawo yokulinganisa cishe ngu-200 - 220°C, kodwa la manani angahluka kuye ngebanga le-TPU.
  • Isikulufu: Isikulufu sijikeleza ngaphakathi komgqomo, sidlulise, sicindezele, futhi sincibilikiseAma-pellet e-TPU.Imiklamo ehlukene yezikulufo (isb., izikulufo eziphumayo zesikulufo esisodwa noma ezimbili) zingathinta ukuxuba, ukusebenza kahle kokuncibilika, kanye nezinga lokukhipha lenqubo yokukhipha. Izikulufo eziphumayo zesikulufo ezimbili ngokuvamile zinikeza ukuxuba okungcono kanye nokuncibilika okufanayo, ikakhulukazi ekwakhiweni okuyinkimbinkimbi.
• Ukuncibilikisa Nokuxuba: Njengoba ama-pellet e-TPU ehamba emgqonyeni, ancibilikiswa kancane kancane ngokuhlanganiswa kokushisa okuvela emgqonyeni kanye nokucheba okubangelwa ukujikeleza kwezikulufo. I-TPU encibilikisiwe ixutshwe kahle ukuqinisekisa ukuncibilika okufanayo.
• Umklamo Nokwakheka Kwedayi: I-TPU encibilikisiwe ibe isiphoqelelwa idayisi, enquma ukuma kwesigaba somkhiqizo okhishwe. Amadayi angenziwa ngokwezifiso ukuze akhiqize izimo ezahlukene, njengeziyindilinga zamashubhu, unxande wamaphrofayili, noma isicaba samashidi namafilimu. Ngemva kokudlula idayisi, i-TPU ekhishwe iyapholiswa futhi iqine, ngokuvamile ngokudlula ebhavini lamanzi noma ngokusebenzisa ukupholisa komoya.

3. Ukucutshungulwa Kweposi

• Ukulinganisa Nokulinganisa: Kweminye imikhiqizo ekhishwe ngaphandle, imisebenzi yokulinganisa nokulinganisa iyadingeka ukuqinisekisa ubukhulu obunembile. Lokhu kungafaka phakathi ukusebenzisa imikhono yokulinganisa, amathangi okulinganisa nge-vacuum, noma amanye amadivayisi ukulawula ububanzi bangaphandle, ukujiya, noma ezinye izilinganiso ezibalulekile zomkhiqizo.
• Ukusika noma Ukugoqa: Kuye ngokusetshenziswa, umkhiqizo we-TPU okhishwe unqunywa ube ubude obuthile (bephrofayili, amashubhu, njll.) noma uboshwe kuma-roll (amashidi namafilimu).
