Acetals e faʻaaogaina e fai ma vaega puipuia mo vaega carbonyl i le faʻaogaina o meaola aua e mautu e tusa ai ma le hydrolysis e faʻavae ma faʻatatau i le tele o vailaʻau faʻamaʻi ma faʻaitiitia.E mafai ona latou puipuia le carbonyl i totonu o se mole (e ala i le tali atu mo sina taimi i le ava malosi) poʻo se diol (e ala i le tali atu mo sina taimi i le carbonyl).O lona uiga, a le o le carbonyl, po'o le ava malosi, po'o mea uma e lua e mafai ona avea ma vaega o le mole o lo'o fa'atonuina lona gaioiga.
PTFE o loʻo i ai mea faʻainisinia aoga mai le vevela cryogenic i le 500 ° F (280 ° C) faʻaauau le vevela auaunaga.O lona coefficient o le fete'ena'iga e maualalo ifo nai lo se isi lava mea.E maualuga foi le okesene.
Fa'atusatusaga o Acetal ma Polymer PTFE/FEP Tau Meatotino
Talosaga Mea
Acetal: Bearings; Bushings; Vaega eletise; Gears; Rollers; Puma & vaega valve.
Polymer PTFE/FEP:Fuli fa'apipi'i;E le'o lubricated bearings;O-mama; Fa'amaufa'ailoga; Capacitors; Semiconductor gaosiga; Vaega eletise vevela maualuga; Gaskets; Valve vaega.
Meatotino Mea
Acetal: E maualalo le susū absorption; Malosi faʻainisinia maualuga ma faʻamaʻaʻaina; Machinability; Lelei kemikolo tetee; Lelei itu mautu.
Polymer PTFE/FEP: Lelei tele meatotino dielectric; Inertness i le tele o vailaʻau; maualuga vevela ma kemikolo tetee; matua maualalo coefficient o feteʻenaʻiga; sili ona tetee le radiation; Sere susu absorption; E le mautonu i le tele o le eletise; Machinability.
