3204 vs 3240 Epoxy Board: Qhov txawv & Xaiv
Epoxy iav ntaub laminates yog dav siv hauv hluav taws xob thiab hluav taws xob rwb thaiv tsev. Hauv kev ua lag luam, ob qho tib si3204thiab3240qib tau hais, tab sis lawv txawv heev nyob rau hauvkev ua raws li tus qauv, cov khoom zoo, kev ua tau zoo sib xws thiab tus nqi. Weshare qhia meej txog lawv qhov sib txawv thiab cov qauv kev xaiv raws li hauv qab no.
1. Basic txhais & Standard
3240 Epoxy Board
Lub teb chaws tus qauv qib (GB/T 1303).
Sib raug rauIEC EPGC201, lees paub thoob ntiaj teb.
Ua los ntawmalkali-dawb hluav taws xob iav ntaub + txheem epoxy resin, kub pressed.
Chav ntsuas kub:B-chav kawm (155 degree).
Nplaim retardancy:UL94 HB(lub hom phiaj dav dav).
Xim:daj(tus qauv).
3204 Epoxy Board
Tsis yog lub teb chaws tus qauv qauv; nws yog akev lag luam feem ntau / Hoobkas tus kheej-sib sau qib.
Qhov tseem ceeb ibEconomy version ntawm 3240, sivtxo nqi iav ntaub thiab resin.
Tsis muaj kev sib koom ua ke IEC lossis GB tus qauv; qhov zoo sib txawv los ntawm cov chaw tsim khoom.
Chav ntsuas kub:Qhov kub thiab txias ntawm qhov kub ntawm 130-150 degrees, tsis ruaj khov.
Nplaim retardancy:HB, feem ntau nrog kev ua haujlwm tsis zoo ntawm tus kheej tua hluav taws.
2. Core Performance Differences
| Yam khoom | 3240 (Standard) | 3204 (Kev lag luam) |
|---|---|---|
| Txuj | GB/T 1303, IEC EPGC201 | Non-standard, Hoobkas-txhais |
| Cov ntaub iav | High-purity alkali-dawb E-iav | Ordinary los yog mix-qib iav ntaub |
| Resin System | Txheem bisphenol-A epoxy | Qib qis epoxy / phenolic sib xyaw |
| Tg (Glass Transition) | Ntau tshaj lossis sib npaug li 130 degree | 110-130℃(tsis ruaj khov) |
| Khoov zog | 380-650 MPa | 250-350 MPa (qis) |
| Dielectric zog | Ntau tshaj lossis sib npaug li 16 kV / mm | 10-14 kV / hli (tsis muaj zog) |
| Moisture Resistance | Zoo, ruaj khov tom qab nqus dej | Tsis zoo, yooj yim nqus dej noo |
| Dimensional Stability | Siab, nruj thickness kam rau ua | Tsis zoo, yooj yim rau warp |
| Nqe | Nruab nrab, tus nqi tsim nyog | Tsawg (10-30% pheej yig dua) |
| Kev sib raug zoo | Stable batch-rau-batch | Loj variation ntawm batch |
3. Cov ntawv thov ib txwm
3240 Epoxy Board
General hluav taws xob rwb thaiv tsev:transformers, low-voltage motors, switchgears.
Mechanical rwb thaiv tsev qhov chaw, fixtures, insulating blocks.
Cov ntawv thov xav tauruaj khov hluav taws xob & mechanical kev ua tau zoo.
Siv hauvtransformer roj thiab nruab nrab humidity ib puag ncig.
3204 Epoxy Board
Tus nqi qis, tsis muaj qhov tseem ceeb ntawm rwb thaiv tsev.
Tej yam yooj yim mechanical kev txhawb nqa, spacers, non-voltage-bearing daim hlau.
Nqi-sensitive tej yaam numnrog tsis muaj kev ntseeg nruj heev.
Qhuav, sab hauv tsev, tsis tshua muaj hluav taws xob ib puag ncig nkaus xwb.
4. Yuav xaiv li cas: 3204 lossis 3240?
Xaiv 3240 yog:
Koj xav tauGB / IEC tus qauv ua rawsthiab ruaj khov zoo.
Ua haujlwm kub130-155 ° C, nruab nrab / siab voltage.
Cov ntawv thov hauvtransformers, motors, hloov txee.
Yuav tsum muaj kev ntseeg siab ntev thiab kev nyab xeeb.
Xaiv 3204 tsuas yog yog tias:
Nyiaj txiag nruj heevthiab cov kev xav tau ntawm kev ua haujlwm tsawg.
Siv raunon-insulating structural fillers, yooj yim spacers.
Qhuav, sab hauv tsev, qis-voltage, tsis tseem ceebdaim ntawv thov.
5. Cov lus xaus
3240=National standard, ruaj khov zoo, txhim khu kev qha rwb thaiv tsev, nruab nrab nqi.
3204=Tsis yog tus qauv, qib kev lag luam, kev ua haujlwm qis dua, tus nqi pheej yig dua.
Rau feem ntau kev lag luam thiab hluav taws xob siv,3240 yog qhov kev nyab xeeb thiab nyiam xaiv; 3204 tsuas yog tsim nyog rau qhov kev thov qis, tus nqi nkaus xwb.
