Cov yam ntxwv ntawmpolyester thiab polyether polyurethaneraws li hauv qab no:
Polyester raws li Polyurethane:
Roj kuj zoo heev
Zoo abrasion kuj
Kev kub ntxhov kuj zoo ib yam li polyether raws polyurethane
Feem ntau ntau ntau thiab txaus siab rau tus nqi kom zoo dua polyether-based PU tubing
Tsis pom zoo rau siv nyob rau hauv high humidity los yog raug dej, raws li qhov ntim swell thiab txo cov khoom yuav tshwm sim.
Polyether raws li polyurethane:
Flexibility ntawm qhov kub thiab txias
Cov kab mob fungal
Ua rau tsis muaj zog acids thiab cov hauv paus
Exceptional stability thaum lub sij hawm hydrolysis
Pom zoo rau cov ntawv thov uas muaj kev ntxhov siab nruab nrab mus rau siab
Kev kub siab tiv thaiv: ib yam li polyester raws li polyurethane
Nyob ruaj khov hauv dej sov li 50 degree (122℉) rau lub sijhawm ntev, tab sis tsis pom zoo rau kev khiav dej ntau tshaj 70 degree (158℉)
Tus nqi nqus dej yog 0.3% mus rau 1% los ntawm qhov hnyav, thiab qhov ntim swell tsis pom zoo.
Ua kom pom kev ruaj khov zoo dua li cov khoom siv ester (kwv yees li tsib xyoos piv rau peb xyoos txee lub neej ntawm cov khoom siv polyester, piv txwv li, tubing)
Feem ntau kim dua li cov khoom siv polyester
Cov dej tsis haum rau kev siv pneumatic
Peb cia siab tias tsab xov xwm sib piv no yuav pab koj xaiv cov khoom siv polyurethane haum rau koj daim ntawv thov.Thov tsis txhob ua siab deb rautiv tauj pebyog koj muaj lus nug.
