Aliphatic moʻo TPU

ʻO nā Aliphatic TPU kahi ʻano kikoʻī o ka polyurethane thermoplastic e hōʻike ana i ke kūpaʻa UV kiʻekiʻe, e kūpono ana iā lākou no nā noi waho kahi e hopohopo ai ka lōʻihi o ka ʻike ʻana i ka lā.
Wahi a nā waiwai kemika o nā ʻāpana lipid diisocyanate, hiki ke hoʻokaʻawale ʻia ka TPU i nā pūʻulu aromatic a me aliphatic. ʻO Aromatic ka TPU maʻamau a mākou e hoʻohana ai (ʻaʻole kū'ē i ka melemele a i ʻole ka hopena melemele ʻaʻole maikaʻi, ʻaʻole ka papa meaʻai), maʻamau ka aliphatic e hana i nā huahana kiʻekiʻe. ʻO nā laʻana e pili ana i nā mea lapaʻau, nā mea e koi ai i ka pale melemele mau, a pēlā aku.
Hoʻokaʻawale ʻia ʻo Aliphatic i polyester / polyether.
Ka helu ʻana o ka pale melemele: Hoʻohālikelike ʻia ia me ke kāleka hina, i māhele ʻia i nā pae 1-5. Ma hope o ka ho'āʻo kūʻē ʻana i ka ʻeleʻele melemele e like me Suntest, QUV a i ʻole ka hoʻāʻo ʻana i ka lā, e hoʻohālikelike i ka hoʻololi kala o ka hāpana ma mua a ma hope o ka hoʻāʻo ʻana, ʻo 5 ka papa maikaʻi loa, ʻo ia hoʻi, ʻaʻohe loli kala. 3 ʻO kēia ka mea i ʻike maopopo ʻia. Ma keʻano laulā, 4-5, ʻo ia hoʻi, ka wehe iki ʻana, ua hālāwai me ka hapa nui o nā noi TPU. Inā ʻaʻole pono ʻoe i ka discoloration, pono ʻoe e hoʻohana i ka TPU aliphatic, ʻo ia hoʻi, ka TPU non-yellowing, ʻaʻole MDI ka substrate, maʻamau HDI a i ʻole H12MDI, etc., a me ka hoʻāʻo UV lōʻihi. ʻaʻole e wehe ʻia.
