3240 Epoxy Phenolic Glass Cloth Base Rigid Laminated Sheet
Zofunikira Zaukadaulo
1.1Maonekedwe:pamwamba pa pepala adzakhala lathyathyathya ndi yosalala, opanda thovu mpweya, makwinya kapena ming'alu ndipo momveka opanda ungwiro ena ang'onoang'ono monga zokopa, mano, ndi zina zotero. Mtundu uyenera kukhala wofanana kwambiri, koma madontho ochepa ndi ovomerezeka.
1.2Dimension ndi kuloledwakulolerana
1.2.1 M'lifupi ndi Utali wa Mapepala

| Ndemanga: Kwa makulidwe osakhala mwadzina omwe sanatchulidwe patebulo ili, kupatuka kudzakhala kofanana ndi makulidwe okulirapo otsatirawa. | |||
1.3Kupindika Kutembenuka
| Makulidwe (mm) | Kupindika Kutembenuka | |
| 1000mm (Utali wa Wolamulira) (mm) | 500mm (Utali wa Wolamulira) (mm) | |

1.4Kukonzekera kwamakina:mapepala adzakhala opanda ming'alu, delaminations ndi zidutswa pamene makina monga macheka, kubowola, lathing ndi mphero.
1.5The thupi, makina ndi magetsi katundu
| Ayi. | Katundu | Chigawo | Mtengo wokhazikika | Mtengo weniweni |
| 1 | Kuchulukana | g/cm3 | 1.7-1.95 | 1.94 |
| 2 | Kumwa madzi (2mm sheet) | mg | ≤20 | 5.7 |
| 3 | Flexural mphamvu, perpendicular kuti laminations | MPa | ≥340 | 417 |
| 4 | Mphamvu zamphamvu (Charpy, notch) | kJ/m2 | ≥30 | 50 |
| 5 | Dielectric dissipation factor 50Hz | --- | ≤5.5 | 4.48 |
| 6 | Dielectric nthawi zonse 50Hz | --- | ≤0.04 | 0.02 |
| 7 | Insulation resistance (Pambuyo pa 24h m'madzi) | Ω | ≥5.0 x108 | 4.9x109 |
| 8 | Mphamvu ya dielectric, perpendicular to laminationsin thiransifoma mafuta pa 90 ℃+/-2 ℃, 1mm pepala | kV/mm | ≥14.2 | 16.8 |
| 9 | Kuwonongeka kwa Voltage, kufanana ndi laminationsin thiransifoma mafuta pa 90 ℃+/-2 ℃ | kV | ≥35 | 38 |
Kulongedza, Kuyendetsa ndi Kusungirako
Zolembazo ziyenera kusungidwa pamalo pomwe kutentha sikudutsa 40 ℃, ndikuyikidwa mopingasa pa bedplate yokhala ndi kutalika kwa 50mm kapena kupitilira apo. Khalani kutali ndi moto, kutentha (zida zotenthetsera) ndi dzuwa. Nthawi yosungiramo mapepala ndi miyezi 18 kuyambira tsiku lochoka kufakitale. Ngati nthawi yosungirayi yadutsa miyezi 18, mankhwalawa atha kugwiritsidwanso ntchito atayesedwa kuti akhale oyenerera.
Ndemanga ndi Zodzitetezera Pakugwiritsa Ntchito
Liwiro lalitali komanso kuya pang'ono kwa g kumagwiritsidwa ntchito popanga makina chifukwa cha kufooka kwa matenthedwe a mapepala.
Kucheka ndi kudula mankhwalawa kumatulutsa fumbi ndi utsi wambiri. Njira zoyenera ziyenera kuchitidwa kuti zitsimikizire kuti fumbi lili m'malire ovomerezeka panthawi yogwira ntchito. Ndikofunikira kuti muchepetse mpweya wotulutsa mpweya komanso kugwiritsa ntchito masks a fumbi/tinthu.
Mapepalawa amakhala ndi chinyezi pambuyo popangidwa ndi makina, kuphimba kwa insulating kumalimbikitsidwa.
