Dab tsi yog qee qhov kev siv siab -kub engineering yas rau cov tshuab kub khiav?

Lub ntsiab siab -kub engineering plastics feem ntau siv hauv cov tshuab kub khiav xws li polyetheretherketone (PEEK), polyimide (PI), polyphenylene sulfide (PPS), kua siv lead ua polymer (LCP), polyetherimide (PEI), thiab polysulfone (PSU). Cov ntaub ntawv no tuaj yeem ua haujlwm ruaj khov rau lub sijhawm ntev dua 150 degree, ua tau raws li qhov yuav tsum tau ua rau siab -precision thiab siab- kev ntseeg siab txhaj tshuaj molding.

1. Polyetheretherketone (PEEK)

Thaum tshav kub kub Resistance: Ntev-lub sij hawm ua hauj lwm kub txog li 250 degree, luv-lub sij hawm withstand 300 degree

Core Advantages: Siab zog, hnav tsis kam, tshuaj corrosion kuj, biocompatibility zoo

Daim ntaub ntawv: Kub khiav nozzles, sealing rings, kho mob -qib pwm Cheebtsam

Kev Ua Haujlwm: Yuav tsum tau ziab ntawm 150℃rau 6 teev, pwm kub 170-200 degree

2. Polyimide (PI)

Thaum tshav kub kub Resistance: Thermal decomposition kub txog 600 degree, kev khiav hauj lwm ntau yam -269℃mus rau 300 degree

Subclass muaj xws li:

PEI (Polyetherimide): HDT kwv yees li 217 degree, nplaim hluav taws zoo heev

PAI (Polyamide{0}}Iimide): Tensile zog 190MPa, HDT txog 274 degree

Daim ntaub ntawv: High-kub sensor sheaths, cua sov coil txhawb, precision insulating Cheebtsam

3. Polyphenylene sulfide (PPS)

Thaum tshav kub kub tsis kam: Ntev -lub sij hawm ua hauj lwm kub siab tshaj 200 degree, HDT mus txog 260℃tom qab iav fiber reinforcement

Qhov zoo: Tus kheej- nplaim hluav taws kub, tsis tshua muaj dej nqus, acid thiab alkali corrosion kuj, zoo heev dimension stability

Daim ntaub ntawv: Terminal blocks, connector vaj tse, shunt board rwb thaiv tsev

Ceebtoom: Tsis txhob muab cov khoom siv rov ua dua tshiab nrog PVC los tiv thaiv chloride ion corrosion

4. Liquid crystal polymer (LCP)

Thaum tshav kub kub tsis kam: Reflow soldering kub tsis kam mus txog 300 degree

Qhov zoo: Ultra-siab fluidity, tsawg shrinkage (0.1%-0.2%), siab modulus

Cov ntawv thov: Cov khoom siv hluav taws xob kub khiav me me, nyias- cov khoom sib txuas, cov khoom siv hluav taws xob

5. Polyetherimide (PEI)

Thaum tshav kub kub kuj: iav hloov kub 215 degree, luv-lub sij hawm kub tsis kam 220 degree

Qhov zoo: UL94 V-0 nplaim retardant ntsuam xyuas, ruaj khov hluav taws xob rwb thaiv tsev, tsawg molding shrinkage.

Daim ntaub ntawv: Kub tswj module vaj tse, sensor brackets, siab - zaus hluav taws xob Cheebtsam.

6. Polysulfone (PSU)

Thaum tshav kub kub ua haujlwm: Ntev-lub sijhawm ua haujlwm kub 180 degree, khaws ntau dua 80% lub zog ntawm 150 degree.

Qhov zoo: Hydrolysis resistant, creep resistant, metallizable.

Daim ntawv thov: Diverter phaj txhawb, siab -kub connectors, kho mob kom tsis muaj menyuam.
