Te rerekētanga i waenga i te TPU polyester me te polyether, me te whanaungatanga i waenga i te polycaprolactone me te TPU

Ko te rerekētanga i waenga i te TPU polyester me te polyether, me te whanaungatanga i waenga iTe Whare Tiaki Tamariki Porakaprolaktoni

Tuatahi, ko te rerekētanga i waenga i te TPU polyester me te polyether

Ko te polyurethane thermoplastic (TPU) he momo rauemi elastomer mahi-teitei, e whakamahia whānuitia ana i roto i ngā mara maha. E ai ki te hanganga rerekē o tōna wāhanga ngohengohe, ka taea te wehewehe i te TPU ki te momo polyester me te momo polyether. He rerekētanga nui te mahi me te tono i waenga i ngā momo e rua.

He kaha teitei te TPU polyester me te ātete ki te kakahu, he tino pai ngā āhuatanga kume, ngā āhuatanga piko me te ātete whakarewa. Hei tāpiri, he pai te ātete ki te pāmahana teitei, ā, he pai mō ngā whakamahinga i roto i ngā taiao pāmahana teitei. Heoi, he ngoikore te ātete ki te waikura o te TPU polyester, ā, he ngāwari ki te whakaekea e ngā ngota wai me te pakaru.

He rerekē,TPU polyetherE mōhiotia ana mō tōna kaha nui, te ātete ki te waikura me te manawanui nui. He tino pai hoki tōna mahi pāmahana iti, he pai mō te whakamahi i ngā taiao makariri. Heoi, he ngoikore te kaha o te kiri me te kaha pakaru o te polyether TPU, ā, he iti iho hoki te ātete ki te kume, te kakahu me te haehae o te polyether TPU i tērā o te polyester TPU.

Tuarua, ko te polycaprolactone TPU

He rauemi pūmua motuhake te Polycaprolactone (PCL), ko te TPU ia he whakarāpopototanga mō te polyurethane thermoplastic. Ahakoa he rauemi pūmua rāua, ehara te polycaprolactone i te TPU. Heoi, i roto i te tukanga whakaputa TPU, ka taea te whakamahi i te polycaprolactone hei wāhanga wāhanga ngohengohe nui hei tauhohe ki te isocyanate hei whakaputa i ngā elastomers TPU me ngā āhuatanga tino pai.

Tuatoru, ko te whanaungatanga i waenga i te polycaprolactone meTPU masterbatch

He mea nui te mahi a te Masterbatch i roto i te hanga TPU. He prepolymer kukū-teitei te Masterbatch, he mea tito mai i ngā momo wāhanga pēnei i te polymer, te plasticizer, te stabilizer, me ētahi atu. I roto i te tukanga hanga TPU, ka taea e te masterbatch te tauhohe ki te mekameka whakaroa, te kaihoko hononga, me ētahi atu, hei whakaputa hua TPU me ngā āhuatanga motuhake.

Hei rauemi pūmua mahi-teitei, he maha ngā wā ka whakamahia te polycaprolactone hei wāhanga nui o te TPU masterbatch. Mā te prepolymerization o te polycaprolactone me ētahi atu wāhanga, ka taea te whakarite i ngā hua TPU he pai ngā āhuatanga miihini, he ātete ki te waikura me te ātete ki te pāmahana iti. He whānuitia ngā tono mō ēnei hua i roto i ngā mara o ngā kākahu kore e kitea, ngā taputapu hauora, ngā hu hākinakina me ētahi atu.

Tuawhā, ngā āhuatanga me ngā tono o te polycaprolactone TPU

E whai whakaaro ana te Polycaprolactone TPU ki ngā painga o te polyester me te polyether TPU, ā, he pai ake ngā āhuatanga whānui. Ehara i te mea he kaha miihini teitei me te ātete kakahu anake, engari he pai hoki te ātete ki te waikura me te ātete pāmahana iti. Nā tēnei ka roa te ora ratonga o te polycaprolactone TPU me te pumau i roto i ngā taiao uaua me te hurihanga.

I roto i te ao o ngā kākahu e kore e kitea, kua noho te polycaprolactone TPU hei rauemi pai rawa atu nā ōna āhuatanga whānui. Ka taea e ia te ātete ki te pirau o ngā āhuatanga o waho pēnei i te ua waikawa, te puehu, te paru manu, ā, ka whakarite i te mahi me te roa o te ora o ngā kākahu motuka. Hei tāpiri, i roto i ngā ao o ngā taputapu hauora, ngā taputapu hākinakina, me ētahi atu, kua arohia whānuitia te polycaprolactone TPU mō tōna haumaru me tōna pono.

I roto i ngā kupu poto, he rerekētanga nui i waenga i te TPU polyester me te polyether i roto i te mahi me te whakamahinga, ko te polycaprolactone, hei tetahi o ngā wāhanga nui o te TPU, ka hoatu ki ngā hua TPU he āhuatanga whānui tino pai. Mā te mārama hohonu ki ngā whanaungatanga me ngā āhuatanga i waenga i ēnei rauemi, ka taea e tātou te whiriwhiri me te whakamahi i ngā hua TPU e tika ana hei whakatutuki i ngā hiahia o ngā mara rerekē.
