High performance material PPO kubva kuSIKO.

PPO zvinhu kubva SIKO

Polyphenylene oxide kana polyethylene ether Inozivikanwawo sepolyphenylene oxide kana polyphenylene ether, itembiricha yepamusoro inodzivirira thermoplastic resin.

Hunhu uye Zvishandiso

PPO ipurasitiki yeinjiniya ye thermoplastic ine hunyanzvi hwekuita, yakasarudzika magetsi ekudzivirira uye kuramba mvura, uye yakanaka dimensional kugadzikana.

1, dielectric zvimiro zveinjiniya mapurasitiki kutanga

PPO resin molecular structure isina yakasimba polar mapoka, yakagadzikana magetsi zvivakwa, inogona kuchengetedza yakanaka magetsi emagetsi munzvimbo dzakasiyana tembiricha uye frequency.

① Dielectric nguva dzose: 2.6-2.8 ndiyo idiki muinjiniya mapurasitiki ② Tangent ye dielectric kurasikirwa Angle: 0.008-0.0042 (inenge isingakanganiswe nekushisa, humidity uye frequency) ③ Vhoriyamu resistivity: 1016 ndiyo yepamusoro muinjiniya mapurasitiki

2, yakanaka mechanicha uye inopisa zvimiro zvePPO molecular chain, ine nhamba yakakura yeanonhuhwirira mhete chimiro, molecular chain senitivity yakasimba, resin mechanical simba rakakwirira, yakanakisa creep resistance, tembiricha shanduko idiki kwazvo. PPO ine yakanyanya kupisa kupisa, girazi shanduko tembiricha inosvika 211 ℃, melting point 268 ℃.

3, yakanakisa kudzivirira kwemvura PPO isiri-crystalline resin, mune yakajairwa tembiricha renji, kushoma molecular kufamba, hapana mapoka makuru epolar mucheni huru, dipole nguva haiitike danda, kuramba kwemvura kwakanaka kwazvo, ndiyo yakaderera yekunyudza mvura. yeinjiniya mapurasitiki emhando. Zvimiro zvaro zvemuviri zvichiri kuderera zvishoma mushure mekunyura mumvura inopisa kwenguva yakareba.

4, Okisijeni indekisi yekuzvidzima PPO ndeye 29, iyo inodzima inodzima, uye iyo oksijeni index ye high impact polyethylene ndeye 17, iyo inopisa zvinhu. Iko kusanganiswa kwezviviri ndeyekupisa kwepakati. Paunenge uchigadzira PPO inodzoreredza moto, hapana chikonzero chekuwedzera halogen murazvo unodzoreredza, kuwedzera phosphorus-ine murazvo unodzoreredza dosi inogona kusvika UL94 standard. Deredza kusvibiswa kune zvakatipoteredza.

5, yakaderera shrinkage mwero, yakanaka dimensional kugadzikana; Isiri-chepfu, yakaderera density 6, dielectric resistance uye light resistance PPO asidhi, alkali uye detergent uye zvimwe zvinokonzeresa ngura, pasi pemamiriro ekushushikana, mineral oil uye ketone, ester solvents inoburitsa kusagadzikana kuputika; Organic solvents senge aliphatic hydrocarbons, halogenated aliphatic hydrocarbons uye anonhuwirira hydrocarbons anogona kunyunguduka nekunyungudika.

PPO kushaya simba ndiko kusamira zvakanaka kwechiedza, nguva refu pasi pezuva kana mwenje wefluorescent kushandiswa kunoburitsa ruvara, ruvara rweyero, chikonzero ndechekuti ultraviolet mwenje inogona kuita kuti cheni yeanonhuwirira ether ipatsanuke. Maitiro ekuvandudza mwenje kuramba kwePPO inova musoro.

Kuitwa kwePPO kunotarisa munda uye chiyero chekushandisa:

①MPPO density idiki, iri nyore kugadzirisa, tembiricha yekupisa mu90-175 ℃, kune akasiyana maratidziro emidziyo, yakanaka dimensional kugadzikana, yakakodzera kugadzirwa kwemidziyo yemuhofisi, midziyo yemumba, mabhokisi emakombuta, chasi uye zvikamu zvemazvo.

② MPPO dielectric inogara uye dielectric kurasikirwa Angle tangent mune mashanu general engineering mapurasitiki ari pasi, ndiko kuti, yakanakisa insulation, uye yakanaka kupisa kupisa, inokodzera indasitiri yemagetsi. Inokodzera kugadzira magetsi ekudzivirira zvikamu, senge coil furemu, chubhu inobata, control shaft, transformer nhovo sleeve, relay bhokisi, insulating mbiru uye zvichingodaro, izvo zvinoshandiswa mukunyorova uye kutakurwa mamiriro.

③ MPPO ine mvura inodzivirira uye inodzivirira kupisa, iyo inokodzera kugadzira mamita emvura, pombi dzemvura uye machubhu eshinda anoshandiswa mumafekitori emachira anoda zvinhu zvinogara kwenguva refu zvevatengi pakubika. Machubhu eshinda akagadzirwa neMPPO ane hupenyu hurefu hwesevhisi.

④ Iyo dielectric inogara uye dielectric kurasikirwa Angle tangent yeMPPO haina kukanganiswa nekushisa uye kutenderera nhamba mumapurasitiki einjiniya, uye ine yakanaka kupisa kupisa uye kugadzikana kwedimensional, iyo inokodzera indasitiri yemagetsi.
