Engineering plastics yog ib hom khoom siv polymer nrog kev ua haujlwm zoo, uas tuaj yeem siv los ua cov khoom siv los tiv thaiv kev ntxhov siab hauv ntau qhov kub thiab siv rau hauv cov tshuaj hnyav thiab lub cev ib puag ncig. Tam sim no daim ntawv thov ntawm engineering plastics yog ntau thiab ntau, uas yog ze rau peb lub neej. Dab tsi yog cov yam ntxwv thiab cov khoom ntawm engineering plastics? Peb kuj paub tias vim li cas engineering plastics thiaj li nrov thiab lees paub hauv khw.
Kev ua tau zoo ntawm engineering plastics:
1. Lub teeb khoom zoo: lub ntiajteb txawj nqus ntawm engineering plastics feem ntau yog hais txog 0.83 ~ 2.2, tsuas yog 1/9 ~ 1/4 ntawm cov hlau thiab 1/2 ntawm txhuas. Qee cov yas engineering, xws li polypropylene, yog qhov sib dua li dej. Cov yam ntxwv ntawm engineering plastics no tseem ceeb heev rau cov cuab yeej siv tshuab xws li tsheb, nkoj thiab dav hlau uas yuav tsum tau txo lawv qhov hnyav.
2. Lub zog tshwj xeeb: Rau cov khoom sib npaug, lub zog ntawm engineering plastics feem ntau qis dua cov hlau. Txawm li cas los xij, piv nrog qhov hnyav tib yam, engineering plastics yog qhov sib zog dua li cov hlau, thiab lub zog ntawm qee qhov engineering plastics yog siab dua li cov hlau zoo tib yam, uas yog cov khoom siv nrog lub zog siab dua ntawm cov khoom siv uas twb muaj lawm. Piv txwv li, qhov hloov kho thiab txhim kho PPS muaj qhov nruj zoo, thiab muaj lub suab hlau thaum cov khoom tsaws.
3. Zoo tshuaj stability: Engineering plastics feem ntau muaj corrosion kuj zoo rau cov kua qaub, alkali thiab lwm yam chemicals, uas yog ib qho zoo heev kom zoo dua. Piv txwv li, polytetrafluoroethylene thiab polyphenylene sulfide muaj kev tiv thaiv corrosion zoo heev, thiab muaj kev cia siab dav rau kev txhim kho hauv cov khoom siv tshuaj tiv thaiv corrosion thiab lwm yam.
4. Cov khoom siv hluav taws xob zoo heev: yuav luag tag nrho cov khoom siv hluav taws xob muaj hluav taws xob zoo, tsis muaj dielectric poob thiab zoo arc tsis kam, uas tuaj yeem muab piv nrog ceramic, roj hmab thiab lwm yam khoom siv insulating. Yog li ntawd, daim ntawv thov ntawm engineering plastics nyob rau hauv lub cev muaj zog, hluav taws xob thiab hluav taws xob kev lag luam muaj ib tug dav heev zeem muag.
5. Antifriction thiab zoo hnav tsis kam: nrog rau qhov no feature, engineering plastics yuav siv tau los tsim ntau yam self-lubricating bearings, zog thiab sealing rings. Engineering plastics kuj muaj qhov zoo tshaj plaws txawv teb chaws faus kev ua tau zoo, uas yog qhov tseem ceeb tshwj xeeb hauv cov xwm txheej hnyav nrog cov khoom abrasive lossis impurities.
6. Kev poob siab zoo thiab kev tshem tawm suab nrov: cov tshuab nruab nrog engineering yas bearings thiab lub zog tuaj yeem txo kev vibration, suab nrov thiab txawm tias tshem tawm suab nrov.
7. Yooj yim molding thiab ua: Engineering cov khoom yas feem ntau tuaj yeem ua pwm nyob rau hauv ib lub sij hawm, thaum cov khoom hlau ib txwm ua tiav los ntawm ob peb, ntau lossis ntau txheej txheem. Cov yam ntxwv ntawm engineering plastics no tseem ceeb heev rau kev txuag cov sij hawm ua hauj lwm thiab txhim kho cov khoom tsim tawm. Tsis tas li ntawd, kev ua haujlwm ntawm cov khoom siv yas engineering yog qhov yooj yim, nrog qhov ntev ruaj khov, cov nqi pwm tsawg thiab cov txiaj ntsig siab.
