Nezve TPU
Aliphatic TPUs imhando chaiyo yethermoplastic polyurethane inodzivirira UV zvakanyanya, zvichiita kuti dzikwanise kushandiswa panze uko kune dambudziko rekuona chiedza chezuva kwenguva refu.
AZvichienderana nehunhu hwemakemikari hwezvikamu zvemafuta e diisocyanate, TPU inogona kukamurwa kuita mapoka e aromatic ne aliphatic. Aromatic ndiyo TPU yatinonyanya kushandisa (isingapindi yero kana kuti yero mhedzisiro yayo haina kunaka, haisi yero grade yechikafu), aliphatic inowanzo shandiswa kugadzira zvigadzirwa zvepamusoro-soro. Mienzaniso inosanganisira zvishandiso zvekurapa, zvinhu zvinoda kuramba yero kusingaperi, nezvimwewo.
ALiphatic yakakamurwawo kuita polyester/polyether.
Kupatsanurwa kwekudzivirira kweyero: Kazhinji kunoenzaniswa nekadhi regrey, rakakamurwa kuita mazinga 1-5. Mushure mekuyedzwa kwekudzivirira yero senge Suntest, QUV kana imwe bvunzo yekubuda muzuva, enzanisa shanduko yeruvara rwemuenzaniso usati waitwa uye mushure mekuedzwa, giredhi rakanakisa i5, zvinoreva kuti hapana shanduko yeruvara. 3 Zvinotevera kusvibiswa kweruvara kuri pachena. Kazhinji, 4-5, kureva kuti, kusvibiswa kweruvara zvishoma, yasangana nekushandisa kwakawanda kweTPU. Kana usingade kusvibiswa kweruvara zvachose, unofanirwa kushandisa aliphatic TPU, kureva iyo inonzi non-yellowing TPU, substrate haisi ye-MDI, kazhinji HDI kana H12MDI, nezvimwewo, uye bvunzo yeUV yenguva refu haizoshanduki ruvara.
