Ihe PPO sitere na SIKO
Polyphenylene oxide ma ọ bụ polyethylene ether A makwaara dị ka polyphenylene oxide ma ọ bụ polyphenylene ether, bụ nnukwu resin thermoplastic na-eguzogide okpomọkụ.
Njirimara na ngwa
PPO bụ plastik injinia thermoplastic nwere arụmọrụ zuru oke, mkpuchi ọkụ eletrik pụtara ìhè na nguzogide mmiri, yana nkwụsi ike akụkụ dị mma.
1, dielectric Njirimara nke engineering plastics mbụ
PPO resin molecular Ọdịdị na-enweghị otu pola siri ike, ihe ọkụ eletrik kwụsiri ike, nwere ike ịnọgide na-enwe ezigbo ọkụ eletrik n'ọtụtụ ọnọdụ okpomọkụ na ugboro ole.
① Dielectric mgbe niile: 2.6-2.8 bụ nke kacha nta na injinịa plastik ② Tangent nke dielectric ọnwụ Angle: 0.008-0.0042 (fọrọ nke nta ka ọ ghara emetụta okpomọkụ, iru mmiri na ugboro ugboro) ③ Volume resistivity: 1016 bụ kasị elu na engineering plastik
2, ezigbo n'ibu na thermal Njirimara nke PPO molecular yinye, nwere ọnụ ọgụgụ dị ukwuu nke aromatic mgbanaka Ọdịdị, molekụla yinye uche siri ike, resin n'ibu ike dị elu, magburu onwe creep iguzogide, okpomọkụ mgbanwe dị nnọọ obere.PPO nwere oke okpomọkụ na-eguzogide, iko mgbanwe okpomọkụ ruo 211 ℃, agbaze ebe 268 ℃.
3, PPO na-eguzogide mmiri dị mma bụ resin na-abụghị kristal, na ọnọdụ okpomọkụ a na-emekarị, obere mmegharị ahụ, ọ dịghị nnukwu ìgwè polar na agbụ isi, oge dipole adịghị eme ogwe osisi, nkwụsị mmiri dị mma nke ukwuu, bụ ọnụ ọgụgụ kachasị elu nke mmiri absorption. ụdị plastik injinia.Ngwongwo anụ ahụ ya ka nwere obere mmebi mgbe ọ gbasasịrị na mmiri ọkụ ruo ogologo oge.
4, Ntugharị oxygen nke PPO na-ekpochapụ onwe ya bụ 29, nke bụ ihe na-ekpochapụ onwe ya, na ikuku oxygen nke nnukwu mmetụta polyethylene bụ 17, nke bụ ihe na-ere ọkụ.Nchikota nke abụọ bụ nke agafeghị oke ọkụ.Mgbe ị na-eme ọkụ retardant PPO, ọ dịghị mkpa ịgbakwunye halogen ire ere retardant, na-agbakwunye phosphorus-nwere ire retardant dose nwere ike iru UL94 ọkọlọtọ.Belata mmetọ na gburugburu ebe obibi.
5, obere shrinkage ọnụego, ezi akụkụ kwụsie ike;Ndị na-adịghị egbu egbu, obere njupụta 6, nguzogide dielectric na nguzogide ọkụ PPO acid, alkali na detergent na corrosion ndị ọzọ bụ isi, n'okpuru ọnọdụ nke nrụgide, mmanụ ịnweta mmanụ na ketone, ester solvents ga-emepụta nrụgide nrụgide;Ihe mgbaze nke organic dị ka aliphatic hydrocarbons, halogenated aliphatic hydrocarbons na aromatic hydrocarbons nwere ike gbazee ma gbazee.
PPO adịghị ike na-adịghị mma na-eguzogide ọkụ, ogologo oge n'okpuru ìhè anyanwụ ma ọ bụ oriọna fluorescent na-emepụta ihe na-emepụta ihe, agba odo, ihe kpatara ya bụ na ìhè ultraviolet nwere ike ime ka agbụ nke ether aromatic kewaa.Otu esi emeziwanye nguzogide ọkụ nke PPO na-aghọ isiokwu.
Arụmọrụ PPO na-ekpebi mpaghara na oke ngwa:
①MPPO njupụta bụ obere, mfe hazie, thermal deformation okpomọkụ na 90-175 ℃, e nwere dị iche iche nkọwa nke ngwaahịa, ezi akụkụ kwụsie ike, adabara imewe nke ụlọ ọrụ ngwá, ezinụlọ ngwa, kọmputa igbe, chassis na nkenke akụkụ.
② MPPO dielectric mgbe niile na dielectric ọnwụ Angle tangent na ise n'ozuzu engineering plastics na kasị ala, ya bụ, ihe mkpuchi kasị mma, na ezigbo okpomọkụ na-eguzogide, kwesịrị ekwesị maka eletriki ụlọ ọrụ.Kwesịrị ekwesị maka ịme akụkụ mkpuchi ọkụ eletrik, dị ka eriri eriri igwe, njide tube, ogwe njikwa, mkpuchi mkpuchi ihe mkpuchi, igbe relay, ogidi mkpuchi na ihe ndị ọzọ, nke a na-eji na ọnọdụ mmiri na ibu.
③ MPPO nwere ezigbo mmiri na-eguzogide mmiri na nguzogide okpomọkụ, nke kwesịrị ekwesị maka ịme mita mmiri, nfuli mmiri na tubes yarn nke a na-eji na ụlọ ọrụ textile na-achọ ngwa ahịa na-adịgide adịgide maka isi nri.Akpa yarn nke MPPO mere nwere ogologo ndụ ọrụ.
④ The dielectric na-adịgide adịgide na dielectric ọnwụ Angle tangent nke MPPO adịghị emetụta okpomọkụ na okirikiri nọmba na engineering plastics, na nwere ezigbo okpomọkụ na-eguzogide na akụkụ kwụsie ike, nke kwesịrị ekwesị maka electronic ụlọ ọrụ.
