Polyoxymethylene tseem hu ua acetal yas yog cov khoom siv thermoplastic uas dav siv hauv kev lag luam tsheb thiab hluav taws xob. Cov khoom siv xav tau muaj kev sib txhuam tsawg, siab nruj thiab ruaj khov qhov ntev zoo. Acetal yog feem ntau siv nyob rau hauv lub iav log, tsom iav, pob bearing thiab kaw tshuab.
Ib yam nkaus, tib neeg nug, cov khoom siv acetal yog dab tsi?
Acetal los yog Polyoxymethylene (POM), feem ntau paub raws li DuPont lub npe Delrin®, yog ib qho khoom siv thermoplastic. Nws yog lub teeb yuag, tsis muaj kev sib txhuam thiab hnav-resistant khoom nrog lub cev zoo thiab ua haujlwm zoo.
Tom qab ntawd, lo lus nug yog, Delrin thiab Acetal zoo ib yam? Acetal yog lub npe nrov rau tsev neeg ntawm cov thermoplastics nrog cov tshuaj npe "PolyOxyMethylene", los yog POM. Acetal muaj nyob hauv ob hom dav dav ntawm cov yas: Copolymer acetal (POM-C), thiab homopolymer acetal (POM-H); nquag hu Delrin ® ib. Txhua yam ntawm acetal nws muaj nws tus kheej txheej ntawm qhov zoo thiab qhov tsis zoo.
Dab tsi yog acetal pas nrig siv rau?
Hex Qws Tshuag: Nyob rau hauv high noo noo los yog submerged daim ntaub ntawv, acetal bearings ua tau zoo tshaj nylon 4 txog 1. Acetal yog qhov zoo tshaj plaws rau cov neeg kho tshuab qhov chaw nyob ze thiab hluav taws xob insulators uas xav tau lub zog thiab nruj. Nws kuj muaj kev tiv thaiv rau ntau yam tshuaj nrog rau ntau cov kuab tshuaj.
Cov yas acetal muaj zog npaum li cas?
Qhov cuam tshuam-hloov kho acetal copolymer resins muaj qhov sib npaug zoo ntawm toughness thiab rigidity, nrog modulus ntawm elasticity siab li 305,000 psi. Qhov no piv rau 435, 000 psi rau lub hom phiaj dav acetal copolymer cob nrog 1.3 ft-lb/in. ua Izod. Acetal copolymers muaj kev tiv thaiv zoo rau cov tshuaj thiab cov kuab tshuaj.
