Peei vs.pom

About Pei tinoda kuziva zvinotevera:

1): PEI iri thermoplastic engineering resin ine yakanakisa kugadzikana uye kuita.

2): Chimwe chezvinhu zvakanakisa zvePEI Resin ndechekuti inogona kutsungirira tembiricha yakanyanya kwenguva yakareba. Iyi yakakwira kupisa kupokana, pamwe nekukatyamadza uye ul Laboratory Certification, inoita PEI Resin inosangana nezvinodiwa zvinodiwa zvekushandisa zvakakwirira.

(3):. Yayo yebhurudhi yakatambanudzwa kwenguva yakareba kuti inogona kusanganiswa zvakasununguka pamwe nemhando dzakasiyana-siyana dzechirongwa-kusvika-kuburitsa bhata. Kunyangwe kana chete 10% girazi fiber kusimbiswa kunowedzerwa, PEI 2100 Resin inochengetedza ductifility pakupisa kubva pasi pezasi kusvika pazasi 200 ×.

(4):. Tichifunga nezve chokwadi chekuti PEI resins show notch agility, inokurudzirwa kutevedzera zvirevo zvechirongwa chehurongwa. Inofanira kuderedza kushandiswa kwesimba masimba emisangano (senge makona akapinza) mune jekiseni rakaumbwa zvikamu zvekupa iyo yakakwira kuve nesimba rekuridza. PEI at * 100 resins inoshandiswa mukushandiswa kwekuda kurova zvakanyanya basa. Iyo isina kuchena izid kukanganisa kweiyi nhevedzano inosvika 15km / mз.

6): Kunyangwe pakupisa uye kushushikana mazinga apo mamwe akawanda maTermoplastics haagone kushandiswa, Pe magiya anoratidza kudzikisira kwakanyanya.

(7). Yakabatanidzwa neiyo yekuvarake uye michina yezvivakwa, izvi zvinoita kuti PEI inoisa sarudzo yakakodzera yekuda kuita zvemagetsi uye magetsi mashandisirwo emagetsi.

(8):. Pei resins dzakakura performance amorphous engineering thermoplastics.

. Mamwe matsotsi ekutengesa anowanikwa ul 94V-0 * pane ukobvu kwe 0.25mm. Mamwe madaridzi anotaridza sosi yekuratidzira yakakwirira dielectric contactric uye yakanyanya kusvibisa zvinhu pamusoro pehuremu hwakawanda hwekupisa uye huwandu. SeAmorphous TherMoplastic Possetherimide, PEI Resin inosanganisa zvakanyanya uye inokonzeresa maitiro, yakakwirira kupisa kupesana uye yakakwirira simba, mwoluus uye general kumakemik yemakemikari mune imwe.

Hunhu hwakakosha hwePEI

2, PEI ine yakasimba yakakwirira-tembiricha yekugadzikana. Kupisa kwekushisa kwekushisa, kupisa kukanganisa kwe tembiricha ye120, kunogona kuve muna -160-180 ℃ yekudziya kwekushandiswa kwenguva refu.

3, hydrolysis kusimba kwakanaka kwazvo, kwakanyanya kupisa kupesana, mupfudze kuramba;

4.Popolyetherherimide ine yakanaka kupokana kune Ultraviolet rays, Y-ray basa.

Basa rakajairika rePolymaldehyde rudzi rwepamhepo rakatsetseka, radiant zvakaoma uye zvakashata zvisingaiti zvinhu, mwenje wero kana chena, wakaomeswa Kuwedzera maitiro ekudzima nyore kudzima, kubva mumoto mushure mekutevedzana kwekudzima, murazvo wokumusoro webhuruu, iko kuguma kwemadonhwe akanyungudutswa, pane chinonamira chinotsamwisa fomualdehyde flavor, hove dzehove.

Polyformaldehyde ndeye chena poda, yakajairika isingaonekwe, gravity yekukura,

Pom's Long Shing-Distant Basa harisi kumusoro, asi nguva pfupi inogona kusvika zana nemakumi matatu, umo homwemelmer of pom pfupi-inodzivirira kupfuura yePom yakakwira kupfuura gumi of pom panzvimbo yehomopolymerization ye pom yakakwirira kupfuura kumusoro uye pasi pegumi ℃. Inogona kushandiswa mu -40 ℃ ℃ ~ 100 ℃ tembiricha yekudziya kwenguva yakareba.

POM iri nyore kuongorora, ongorora tembiricha yemadhigiri 280, ongorora iyo inotsamwisa gasi rinoitika. Naizvozvo, chigadziko chechiumbwa chinofanira kushandiswa kuburitsa misodzi-inodzivirira zvishandiso zvekushandisa.

Mechanical basa resimba rePom, kuomarara kwakanyanya, kugona kwakanaka, kwakanaka kupokana. Basa rayo rekuita rakanaka, pane simba rinosvika makumi mashanu.5mpa.

Basa rayo rekuita rakanakisa, iro ranyatsogona kusvika 50.5mpa, pane kuomarara, uye simbi zviri pedyo neyekuchinja kwePom. .

Simba rekurova rakakwira rakakwira, asi iyo general inorova isingasviki Abs nePC; POM ine hanya negeji, kunze kwegomba kunogona kuita kuti simba rekurova richirovera se90%.

Simba remafuta rinopera simba rakanyanya,

Pom Creep yakafanana ne pa, na20 ℃, 21mpa, 3000h apo chete 2.3%, uye nekudziya idiki kwazvo.

Pom's Friction Factor idiki, yakanaka kupfeka kurwisa (pom> PA6> PAAS> HPVC> PC yePV) yakakura kwazvo, kuzvinyudza kwakanaka.

Zvigadzirwa zvePOM pane kugeda, yakakwira mutoro mhedzisiro inowanzo kuve pedyo-kupopota ruzha.

Basa remagetsi rekusimbisa kwemagetsi kwePOM riri nani, rinenge rakazvimirira rekushisa uye humidity; dielectric nguva dzose uye dielectric kurasikirwa kwakasiyana-siyana kwekushisa tembiricha, humidity uye frequency shanduko idiki kwazvo; arc kuramba kwakanaka, uye inogona kuchengetwa pakupisa kwakanyanya.

Simba reDilelectric yePom ine chekuita neiyo ukobvu

Basa rezvakatipoteredza POM haripikisiki kune yakasimba Acids uye oxidizers, enic acid uye inokonzeresa hydrocarbons. etc., uye inogona kuchengetwa pakupisa kwakanyanya nemakemikari anofungidzirwa. Diki mvura yekunyudza, yakanaka dimensional kugadzikana.

Pom Eathering haina kunaka, kwenguva refu muchikamu cheiyo Ultraviolet mwenje, mashini basa rekutakura, kunze kwekungoitika kweCHALKY uye kupaza. Kugadzira crystalline zvinhu, yakatetepa yekunyungudika, inokurumidza kunyungudika uye kusimbisa, tembiricha yezvinhu zvishoma pazasi pekudziya kwekunyungudika kunoitika. Basa repakati. Kunyorova kunyorova idiki, haigone kuve isingafungirwe nekuoma.
