Xaiv qhov tsim nyog siab -kub engineering plastics rau kub khiav tshuab yuav tsum muaj kev xav txog kev ua haujlwm kub, cov khoom siv hluav taws xob, hluav taws xob rwb thaiv tsev, tshuaj tiv thaiv corrosion, thiab kev sib raug zoo nrog cov thev naus laus zis ua haujlwm. Cov nram qab no yog cov kev xaiv logics thiab cov ntaub ntawv pom zoo rau kev ua haujlwm sib txawv, nrog cov lus pom zoo kom haum rau cov yam ntxwv ntawm Wuhan qhov siab - kub thiab siab - av noo ib puag ncig.
1. Kev xaiv khoom raws li kev ua haujlwm kub

Qhov kub thiab txias |
Khoom siv pom zoo |
Tus Neeg Sawv Cev Qauv / Kev Hloov Kho Kev Qhia |
|
150-180 degrees |
PEI (Polyetherimide), PSU (Polysulfone) |
Ultem 1000, Udel P-1700 |
|
Kub ntawm 180-220 degrees |
PPS (Polyphenylene Sulfide), M-PPO (Modified Polyphenylene Oxide) |
Ryton R4, NORYL GTX |
|
220-260 degree |
PEEK (Polyetheretherketone), PAI (Polyamide{0}}Imide) |
Victrex 450G, Torlon 4203 |
|
>260 degree |
LCP (Liquid Crystal Polymer), PI (Polyimide) |
Zenite 7130, Vespel SP-1 |
Daim ntawv qhia tswv yim rau Wuhan: Thaum lub caij ntuj sov, pwm ambient kub feem ntau tshaj 40℃thiab av noo mus txog 80%. Ua ntej qis- ya raws- nqus thiab hydrolysis- cov ntaub ntawv tiv taus xws li PSU thiab PPS kom tsis txhob tawg lossis rwb thaiv tsev tsis ua haujlwm vim qhov nqus dej noo.
2. Sib piv cov khoom siv rau kev ua haujlwm
Kev Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob (piv txwv li, ntsuas kub tswj modules, sensors)
Nyiam: PEI lossis PES: ruaj khov dielectric tas li, UL94 V-0 nplaim retardant, haum rau high-frequency teeb liab kis tau tus mob ib puag ncig.
Lwm txoj hauv kev: M-PPO: Cov khoom siv hluav taws xob zoo heev, tab sis zam kev sib cuag nrog cov kuab tshuaj organic.
High Mechanical Load Cheebtsam (piv txwv li, nozzles, manifolds)
Nyiam: PEEK lossis PAI: Muaj zog nkag siab, tsis deform nyob rau hauv lub sijhawm ntev - siab.
Kev Lag Luam Kev Lag Luam: PPS + GF30: Tom qab iav fiber ntau ntxiv, HDT tuaj yeem ncav cuag 260 degree, txo cov nqi ntau dua 30%.
Corrosion Resistance thiab Tus Kheej -Tshwj xeeb yuav tsum tau ua (xws li, connectors, sealing rings)
Preferred: LCP or PPS: Dense surface, resistant to acid and alkali cleaning agents, suitable for frequent disassembly and maintenance.
Nco tseg: Tsis txhob siv POM- hom ntaub ntawv, vim lawv yooj yim tso formaldehyde thaum kub kub, corroding hlau Cheebtsam.
3. Cov Lus Qhia Txog Kev Ua Haujlwm thiab Kev Kho Kom Zoo
Kev ziab kom qhuav: PEI thiab PES yuav tsum ziab ntawm 140℃rau 4-6 teev, nrog cov dej noo tswj tau<0.02%. PEEK is recommended to be dried at 150℃ for 6 hours to prevent melt degradation.
Pwm Kub Tswjhwm: PPS raug pom zoo kom molded ntawm 110-130℃los txhim kho crystallinity thiab seem stability. LCP tuaj yeem siv qhov qis- pwm kub (80-100 degree) kom txo lub sijhawm voj voog.
Wuhan Kev Pabcuam Hauv Zos: BLS thiab Sujia muab siab - cov txheej txheem yas molding kub, suav nrog cov kab nkhaus kom qhuav, ntsuas qhov ntsuas kub, thiab lub tsev qiv ntawv tsis ua haujlwm, txhawb kev debugging.
