Ma Acetals amagwiritsidwa ntchito ngati magulu oteteza magulu a carbonyl mu kaphatikizidwe ka organic chifukwa amakhala okhazikika pokhudzana ndi hydrolysis ndi zoyambira komanso pokhudzana ndi ma oxidizing ambiri ndi othandizira kuchepetsa.Atha kuteteza carbonyl mu molekyulu (pochitapo kanthu kwakanthawi ndi mowa) kapena diol (mwakuyankha kwakanthawi ndi carbonyl).Ndiko kuti, mwina carbonyl, kapena ma alcohols, kapena onse atha kukhala gawo la molekyulu yomwe reactivity yake iyenera kuyendetsedwa.
PTFE ili ndi zinthu zothandiza zamakina kuchokera ku kutentha kwa cryogenic pa 500 ° F (280 ° C) kutentha kosalekeza kwautumiki.Coefficient of friction yake ndi yotsika kuposa zinthu zina zilizonse.Lilinso ndi mlingo wochuluka wa okosijeni.
Kuyerekeza kwa Acetal ndi Polymer PTFE/FEP Property Values
Ntchito Zofunika
Acetal:Bearings;Bushings;Zigawo zamagetsi;Magiya;Roller;Pampu & ma valve.
Polima PTFE / FEP: Cabling zothetsera; Non mafuta fani; O-mphete; Zisindikizo; Capacitors; Semiconductor kupanga; High kutentha mbali magetsi; Gaskets; Vavu zigawo.
Zinthu Zakuthupi
Acetal: Mayamwidwe otsika chinyezi; Mphamvu yayikulu yamakina ndi kusasunthika; Kuchita bwino; kukana kwabwino kwamankhwala; Kukhazikika kwabwino kwa mawonekedwe.
Polima PTFE/FEP:Zabwino kwambiri dielectric katundu;Kusalimba kwa mankhwala ambiri;Kutentha kwakukulu ndi kukana mankhwala;Otsika kwambiri coeffiecient wa mikangano;Wabwino cheza kukana;Ziro chinyezi mayamwidwe;Pamlingo wosamva mphamvu pafupipafupi;Kutheka.
