Kev ua tau zoo PPPO los ntawm Siko.

PIPO khoom siv los ntawm Siko

Polyphenylene oxide lossis polyethylene ether tseem hu ua polyphenylene oxide lossis polyphenylene ether, yog qhov kub kub tiv taus thermoplastic resin.

Cov yam ntxwv thiab cov ntawv thov

PPO yog ib lub thermoplastic engineering engineering engineering engineering engineering engineering, rwb thaiv hluav taws xob zoo heev, thiab kev tawm tsam dej zoo.

1, Dielrictric thaj chaw ntawm engineering plastics ua ntej

PPO Letin qauv molecular yam tsis muaj cov pab pawg polar, ruaj khov hluav taws xob, tuaj yeem tswj cov hluav taws xob hluav taws xob zoo hauv ntau qhov kub thiab zaus.

① dielectric constant: 2.8 yog qhov tsawg tshaj plaws hauv kev tsim kho kom sov: 0.0042 (yuav luag tsis cuam tshuam los ntawm kev tiv thaiv thaum muaj kev cuam tshuam: 1016 yog qhov siab tshaj plaws hauv engineering cov huab cua plastics

2, cov khoom siv kho kom zoo thiab cov cua sov ntawm PPO molecular charpositivity yog siab, zoo heev creep kuj, kub hloov yog me me. PPO muaj qhov kub tiv thaiv, ntsuas kub hloov mus txog 211 ℃, melting point 268 ℃.

3, cov dej zoo ua tsis tau loj yog cov khoom siv tsis yog-crystalline, tsis muaj cov roj av li ib txwm muaj, cov roj av tsawg dua yog qhov ua tau zoo heev, yog qhov qis tshaj dej uas nqus dej qis dua ntawm cov engineering tej yam. Nws cov khoom siv lub cev tseem muaj kev cuam tshuam me ntsis tom qab so dej sov ntev.

4, cov pa oxygen ntawm tus kheej-extinguishing PPO yog 29, uas yog cov khoom siv tus kheej, thiab cov pa oxyethylene yog 17, uas yog cov khoom siv tawv nqaij. Kev sib xyaw ntawm ob yog cov muaj pes tsawg npliag. Thaum ua nplaim Retardant PPO, tsis tas yuav ntxiv harogen nplaim retardant, ntxiv phosphorus-muaj nplaim taws retardant koob tuaj yeem ncav cuag ul94 tus qauv. Txo kev ua qias tuaj rau ib puag ncig.

5, Qis qhov qis dua, txoj kev ruaj khov zoo; Tsis-toxic, qis ntom 6, dielectric tiv taus ppposion, nyob rau lwm qhov kev ntxhov siab thiab lwm yam roj av yuav ua rau kev ntxhov siab; Organic kuab tshuaj xws li cov pob zeb roj av, halogenated aliphatic hydrocarbons thiab cov ntxhiab hydrocarbons muaj peev xwm yaj thiab yaj.

PPO tsis muaj zog yog lub teeb tsis zoo, ntev ntev nyob rau hauv lub hnub ci lossis lub laj thawj fluorescent muaj peev xwm ua tau txoj saw ntawm cov ntaub txaij ether split. Yuav ua li cas txhawm rau txhim kho lub teeb tsis kam ntawm PPO ua lub ncauj lus.

Kev ua yeeb yam ntawm PPO txiav txim thaj teb thiab cov nyom ntawm daim ntawv thov:

①MPPO ceev yog me me, yooj yim rau cov txheej txheem, thermal deformation kub hauv 90-1, muaj ntau yam khoom siv hauv tsev, cov thawv khoos phis tawj, chassis thiab cov khoom siv hluav taws xob.

② MPPO Dielectric tas li thiab dielectric tsis Tao tangent hauv qhov qis dua, thiab cov cua sov zoo tshaj plaws, haum rau kev lag luam hluav taws xob. Haum rau kev ua kom cov hluav taws xob qhov chaw, xws li coil ncej, tswj ntaub qhwv, relform

③ MPPO muaj cov dej ua tau zoo thiab kub tsis kam, uas yog tsim nyog rau kev ua cov dej me me uas siv cov neeg siv khoom ruaj khov rau kev ua noj ua haus. Cov xov paj paj ua los ntawm MPO muaj lub neej kev pabcuam ntev.

④ Lub dielectric tas li thiab diilium
