Ndeupi musiyano uripo pakati pe pe uye zvinhu zvinhu?

PEI (Polyetherimide, Polyetherimide) ndeye amber inojekesa yakasimba uye yakaderera puroyi, neyakaderera indekisi yeUl94-v-0, uye density ye 1.28 ~ 1.42g / cm3. PEI ine yakasimba yakakura tembiricha yekugadzikana, uye kunyangwe kana isiri-yakasimbiswa pei, ichine kuomarara kwakanaka nesimba rakanaka. Naizvozvo, pei yakakwirira yePee Formal kugadzikana inogona kushandiswa kuita michina yekupisa-kupisa-inodzivirira. PEI ine zvinhu zvakanakisa zvekushandisa, kurwisa kwesimbe, kurwisa kwakakwirira uye kupfeka kudzikisira, uye kunogona kupfuudza zvakare kupokana kwakanaka, kupokana kwemakemikari uye zvemagetsi zvekusimbisa kwemagetsi. PEI zvakare ine yakanyanya kuderera shringer rate uye yakanaka isotropic mechanical zvivakwa. Kuwedzera girazi fiber, kabhoni fiber kana mamwe mafirita anogona kuzadzisa chinangwa chekusimbiswa kwekugadziridzwa; Inogona zvakare kushandiswa pamwe nema-engineering mapuranga kuti ugadzire iyo yekupisa-inodzivirira polymer Alloy, iyo inogona kushandiswa pasi pekushanda kwekushanda kwe -160 ~ ℃ kwenguva yakareba.

Pe (Polyethyle) Chirungu Zita: Polyethyle Srathity Gravity Sravity: 1.5-3.6% Kuomesa Mamiriro ezvinhu: chlornated, kurwiswa kwakagadziridzwa, girazi riripo rakasimbiswa. Kudzvinyirira kwakaderera polyethyle kune yakanyanya kunyungudika, kuomarara, kuomarara uye nesimba, mvura yakaderera, zvinhu zvakanaka zvemagetsi uye radiation kuramba; Kumanikidza kwepamusoro polyethyle kune kugona kwakanaka, elongation, kukanganisa simba nekuparara; Ultra-yakakwira molecular uremu polyethyle ine simba rakakura, simba rinopera simba uye kupfeka kuramba. Kudzvinyirira kuderera polyethyle kwakakodzera kugadzira zvikamu zvinodzivirira zvinodziya uye zvikamu zvekusimbisa; Kukwirisa kwepamusoro polyethyle kwakakodzera kuita mafirimu, nezvimwewo.; Uhmwpe yakakodzera kugadzira kuvhundutsa kutora, pfeka zvinodzivirira uye nekuendesa zvikamu.
