Urukurikirane rwa alifatique TPU

Aliphatic TPUs nubwoko bwihariye bwa polyurethane ya termoplastique yerekana imbaraga za UV nyinshi, bigatuma ikoreshwa muburyo bwo hanze aho kumara igihe kinini kumurasire yizuba biteye impungenge.
Ukurikije imiti yimiti ya diisocyanate ya lipide, TPU irashobora kugabanywamo amatsinda ya aromatic na aliphatic. Aromatic ni TPU ikunze gukoreshwa (ntabwo irwanya ingaruka z'umuhondo cyangwa umuhondo ni mbi, ntabwo ari ibiryo), alifatique muri rusange ni ugukora ibicuruzwa byinshi byo mu rwego rwo hejuru. Ingero zirimo ibikoresho byubuvuzi, ibikoresho bisaba kwihanganira umuhondo uhoraho, nibindi.
Alifatique nayo igabanyijemo polyester / polyether。
Itondekanya ryumuhondo wumuhondo: Mubisanzwe ugereranije namakarita yumukara, ugabanijwe murwego 1-5. Nyuma yikizamini cyumuhondo cyumuhondo nka Suntest, QUV cyangwa ikindi kizamini cyerekana izuba, gereranya ihinduka ryamabara yicyitegererezo mbere na nyuma yikizamini, amanota meza ni 5, bivuze ko ahanini ntahinduka ryamabara. 3 Ibikurikira ni amabara agaragara. Muri rusange, 4-5, ni ukuvuga, amabara make, yahuye na progaramu nyinshi za TPU. Niba udakeneye ibara na gato, muri rusange ukeneye gukoresha alifatique TPU, ni ukuvuga, ibyo bita TPU idafite umuhondo, substrate ntabwo ari MDI, muri rusange HDI cyangwa H12MDI, nibindi, hamwe nikizamini cya UV kirekire. Ntabwo izahindura ibara.
