PPO khoom los ntawm SIKO
Polyphenylene oxide los yog polyethylene ether Kuj hu ua polyphenylene oxide los yog polyphenylene ether, yog cov kub kub resistant thermoplastic resin.
Cov yam ntxwv thiab kev siv
PPO yog ib qho thermoplastic engineering yas uas muaj kev ua tau zoo heev, rwb thaiv tsev hluav taws xob zoo thiab dej tsis kam, thiab qhov zoo ntawm qhov ntev.
1, dielectric zog ntawm engineering plastics ua ntej
PPO resin molecular qauv tsis muaj pawg polar muaj zog, cov khoom siv hluav taws xob ruaj khov, tuaj yeem tswj tau cov khoom hluav taws xob zoo hauv ntau qhov kub thiab ntau zaus.
① Dielectric tas li: 2.6-2.8 yog qhov tsawg tshaj plaws hauv engineering plastics ② Tangent ntawm dielectric poob lub kaum sab xis: 0.008-0.0042 (yuav luag tsis cuam tshuam los ntawm qhov kub thiab txias, av noo thiab zaus) ③ Volume resistivity: 1016 yog qhov siab tshaj plaws hauv engineering plastics
2, zoo mechanical thiab thermal zog ntawm PPO molecular saw, muaj ib tug loj tus naj npawb ntawm aromatic nplhaib qauv, molecular saw rhiab heev yog muaj zog, resin mechanical zog yog siab, zoo heev creep kuj, kub hloov yog heev me me. PPO muaj kev kub siab ua haujlwm, iav hloov kub mus txog 211 ℃, melting point 268 ℃.
3, dej tsis kam zoo PPO yog non-crystalline resin, nyob rau hauv ib txwm kub ntau, tsawg molecular zog, tsis muaj pawg loj polar nyob rau hauv lub ntsiab saw, dipole lub sij hawm tsis tshwm sim ncej, dej kuj yog zoo heev, yog tus nqi qis tshaj dej nqus. ntawm engineering plastics ntau yam. Nws lub cev muaj zog tseem muaj kev puas tsuaj me me tom qab soaking hauv dej kub rau lub sijhawm ntev.
4, Cov pa oxygen Performance index ntawm tus kheej tua PPO yog 29, uas yog cov khoom siv tua tus kheej, thiab cov pa oxygen Performance index ntawm polyethylene siab yog 17, uas yog cov khoom tawg. Qhov sib xyaw ua ke ntawm ob yog qhov nruab nrab flammability. Thaum ua cov nplaim hluav taws xob PPO, tsis tas yuav ntxiv cov nplaim hluav taws xob halogen, ntxiv phosphorus-muaj cov nplaim hluav taws kub hnyiab tuaj yeem ncav cuag UL94 tus qauv. Txo cov pa phem rau ib puag ncig.
5, tsawg shrinkage tus nqi, zoo seem stability; Non-toxic, low density 6, dielectric resistance and light resistance PPO acid, alkali thiab detergent thiab lwm yam kev txhim kho corrosion, nyob rau hauv cov xwm txheej ntawm kev ntxhov siab, ntxhia roj thiab ketone, ester cov kuab tshuaj yuav tsim kev ntxhov siab tawg; Cov kuab tshuaj organic xws li aliphatic hydrocarbons, halogenated aliphatic hydrocarbons thiab muaj ntxhiab hydrocarbons tuaj yeem yaj thiab yaj.
PPO tsis muaj zog yog lub teeb tsis zoo, lub sij hawm ntev nyob rau hauv lub hnub ci lossis fluorescent teeb siv ua kom tsis muaj xim, xim daj, yog vim li cas yog lub teeb ultraviolet tuaj yeem ua rau cov saw hlau ntawm cov ntxhiab ether tawg. Yuav ua li cas los txhim kho lub teeb tsis kam ntawm PPO ua ib lub ntsiab lus.
Kev ua tau zoo ntawm PPO txiav txim siab txog thaj chaw thiab thaj tsam ntawm daim ntawv thov:
①MPPO qhov ceev yog me me, yooj yim rau kev khiav lag luam, thermal deformation kub hauv 90-175 ℃, muaj cov khoom sib txawv ntawm cov khoom, kev ruaj ntseg zoo, haum rau cov khoom siv hauv chaw ua haujlwm, khoom siv hauv tsev, lub thawv computer, chassis thiab precision qhov chaw.
② MPPO dielectric tas li thiab dielectric poob lub kaum sab xis nyob rau hauv tsib lub dav dav engineering plastics nyob rau hauv qis tshaj, uas yog, qhov zoo tshaj plaws rwb thaiv tsev, thiab zoo tshav kub kuj, haum rau cov hluav taws xob kev lag luam. Haum rau kev ua hluav taws xob insulating qhov chaw, xws li coil ncej, tube tuav, tswj ncej, transformer shield tes tsho, relay box, insulating ncej thiab lwm yam, uas yog siv nyob rau hauv ntub thiab loaded tej yam kev mob.
③ MPPO muaj cov dej tsis zoo thiab kub tsis kam, uas yog tsim los ua cov ntsuas dej, cov twj tso kua mis thiab cov xov paj siv nyob rau hauv textile factories uas xav tau cov khoom siv ruaj khov rau kev ua noj. Cov xov paj ua los ntawm MPPO muaj lub neej ua haujlwm ntev.
④ Lub dielectric tas li thiab dielectric poob Lub kaum sab xis ntawm MPPO tsis cuam tshuam los ntawm qhov kub thiab txias hauv cov khoom siv hluav taws xob, thiab muaj cov cua sov zoo thiab qhov ruaj khov, uas tsim nyog rau kev lag luam hluav taws xob.
