Musiyano uripo pakati pe pei uye peek

Musiyano uripo pakati pe pei uye peek

Pi ini ndinoreva polyetherimide (polyetherimide), iyo zvakare chidimbu chePolyethyleimideimiye uye vashandi vanobudirira. Polyetherimide, Polyetherimide akapfupikiswa pei, ane ruvara-ruvara rwepamhepo rakapetwa neremberi, neyakaderera indekisi yeul94-v-0, uye density ye12 kusvika 1.42 g / cm3.

PolyethetherThe (peek) Resin itsanyo reinjini Kupokana, pfeka kuramba kusasimba nitric nitric acid, radiation kurwisa, mashini manhamba anogona kushandiswa mumuchina wepamusoro uye mhizha uye humwe hunyanzvi uye humwe hunyanzvi.

1. Chii chinonzi pei? Chii chinonzi peek?

Peek: A THERMplastic Injiniya Purasitiki ine zvinhu zvakanakisa, iyo ine 4% idzo endeget kana carboxide mapoka akakwenenzverwa neanopfuura makumi matanhatu muzana. Peek ine yakanaka kupisa kupokana, makemikari kugadzikana, oxidation kuramba uye masimba masimba simba. Iyo ine inonyungudika yenyaya ye 342 ° c uye tembiricha yemadhiraivhi ye 340 ° C, iyo inoita kuti ive yakanaka munzvimbo dzakakwirira-tembiricha. Uye zvakare, peek ine yakanaka kwazvo yemagetsi insulation uye murazvo unodzora zvivakwa.

PEI: PEI iri Coplymer yePeek uye nhamba yevamwe polymers, kazhinji inosanganisira 35-45% peek uye 65-75% vamwe polymers. Zvivakwa zvePei zvinowira pakati peavo vepurasitiki einjiniya enjini senge pa66 ne pa6. Iyo yekunyungudika pfungwa yePEI yakakwira kusvika 290 ×, uye iyo yekudziya yemadhisheni yakakwirira kusvika 248 ℃.

2. Pei uye peek mune dzinoverengeka zvikamu zvemusiyano

(1) Kugadzikana kwekunyora PEI inogona kuchengetedza zvimiro zvaro zvemakanika uye makemikari kugadzikana kune yakakwirira tembiricha, nepo peek ichapfekedza, kuyerera uye oxidation pakudziya kwakanyanya.

. Semuenzaniso, PEI ine simba rakakwirira kwazvo rakajeka uye kuomarara pane peek. Nekudaro, musiyano uyu hauna kukosha mune zvakawanda zvekushandisa, uye nekuda kwekunyungudika kwepamusoro hwekunyungudika uye kuyerera kwakanaka, zvinogona kuve zvinobatsira mu jekiseni rekuumba.

Mukupfupikisa, PEI uye PEEKI pane mapurasitiki emapuranga akafanana akafanana nenzira dzakawanda, asi zvakare ane akawanda misiyano mizhinji.
