I-Aliphatic series TPU

I-Aliphatic TPUs wuhlobo oluthile lwe-thermoplastic polyurethane ekhombisa ukumelana ne-UV ephezulu, okuwenza afanelekele izinhlelo zokusebenza zangaphandle lapho ukuchayeka isikhathi eside elangeni kuwukukhathazeka.
Ngokwezakhiwo zamakhemikhali zezingxenye ze-disocyanate lipid, i-TPU ingahlukaniswa ngamaqembu anamakha kanye ne-aliphatic. I-aromatic i-TPU evamile kakhulu esiyisebenzisayo (engamelani nokuphuzi noma umphumela wokuphuzi umpofu, hhayi izinga lokudla), i-aliphatic ngokuvamile iwukwenza imikhiqizo eminingi ephezulu. Izibonelo zifaka izinsiza zezokwelapha, izinto ezidinga ukumelana nokuphuzi unomphela, nokunye.
I-Aliphatic nayo ihlukaniswe i-polyester / polyether.
Ukuhlukaniswa kokumelana nokuphuzi: Ngokuvamile kuqhathaniswa nekhadi elimpunga, lihlukaniswe ngamazinga angu-1-5. Ngemuva kokuhlolwa kokumelana namabala aphuzi njenge-Suntest, QUV noma okunye ukuhlolwa kokuchayeka elangeni, qhathanisa ukushintsha kombala wesampula ngaphambi nangemuva kokuhlolwa, ibanga elingcono kakhulu ngu-5, okusho ukuthi ngokuyisisekelo alukho ushintsho lombala. 3 Okulandelayo ukuguquguquka okusobala. Ngokuvamile, i-4-5, okungukuthi, ukushintsha umbala kancane, ihlangabezane nezinhlelo zokusebenza eziningi ze-TPU. Uma ungakudingi nhlobo ukushintsha kombala, ngokuvamile udinga ukusebenzisa i-aliphatic TPU, okungukuthi, i-TPU ebizwa ngokuthi ayiphuzi, i-substrate akuyona i-MDI, ngokuvamile i-HDI noma i-H12MDI, njll., kanye nokuhlolwa kwe-UV yesikhathi eside. ngeke ishintshe umbala.
