3240 Epoxy Phenolic Glass Cloth Base Rigid Laminated Sheet
Izidingo Zobuchwepheshe
1.1Ukubukeka:ingaphezulu leshidi lizoba sicaba futhi libushelelezi, lingabi namabhamuza omoya, imibimbi noma imifantu futhi lingabi nakho okunye ukungapheleli okuncane okufana nokuklwebheka, amazinyo, njll. Unqenqema lweshidi kufanele lucoceke futhi lungabi nama-delaminations kanye nokuqhekeka. Umbala uzofana kakhulu, kodwa amabala ambalwa avumelekile.
1.2Ubukhulu nokuvunyelwaukubekezelelana

| 0.5 0.6 0.8 1.0 1.2 1.6 2.0 2.5 3.0 4.0 5.0 6.0 8.0 | +/-0.12 +/-0.13 +/-0.16 +/-0.18 +/-0.20 +/-0.24 +/-0.28 +/-0.33 +/-0.37 +/-0.45 +/-0.52 +/-0.60 +/-0.72 | 10 12 14 16 20 25 30 35 40 45 50 60 80 | +/-0.82 +/-0.94 +/-1.02 +/-1.12 +/-1.30 +/-1.50 +/-1.70 +/-1.95 +/-2.10 +/-2.30 +/-2.45 +/-2.50 +/-2.80 |
| Amazwana: Ngobukhulu obungekona okwegama okungabaliwe kuleli thebula, ukuchezuka kuzofana nokuqina okukhulu okulandelayo. | |||
1.3Ukugoba Ukuchezuka
| Ubukhulu (mm) | Ukugoba Ukuchezuka | |
| 1000mm (Ubude berula) (mm) | 500mm (Ubude berula)(mm) | |
| 3.0-6.0 ＞6.0–8.0 ＞8.0 | ≤10 ≤8 ≤6 | ≤2.5 ≤2.0 ≤1.5 |
1.4Ukucutshungulwa komshini:amashidi ngeke abe nemifantu, ama-delaminations kanye nezinsalela lapho kusetshenziswa imishini efana nokusaha, ukubhoboza, ukugaya kanye nokugaya.
1.5Izakhiwo zomzimba, zemishini kanye nezikagesi
| Cha. | Izakhiwo | Iyunithi | Inani elijwayelekile | Inani elijwayelekile |
| 1 | Ukuminyana | g/cm3 | 1.7-1.95 | 1.94 |
| 2 | Ukumuncwa kwamanzi (2mm ishidi) | mg | ≤20 | 5.7 |
| 3 | Amandla e-Flexural, perpendicular to laminations | I-MPa | ≥340 | 417 |
| 4 | Amandla omthelela (Charpy, notch) | kJ/m2 | ≥30 | 50 |
| 5 | I-Dielectric dissipation factor 50Hz | --- | ≤5.5 | 4.48 |
| 6 | I-Dielectric njalo 50Hz | --- | ≤0.04 | 0.02 |
| 7 | Ukumelana ne-insulation (Ngemva kwamahora angu-24 emanzini) | Ω | ≥5.0 x108 | 4.9 x109 |
| 8 | Amandla e-Dielectric, perpendicular to laminationsin transformer oil at 90℃+/-2℃, 1mm ishidi | kV/mm | ≥14.2 | 16.8 |
| 9 | I-Breakdown Voltage, ehambisana nowoyela we-laminationsin transformer ku-90 ℃+/-2 ℃ | kV | ≥35 | 38 |
Ukupakisha, Ezokuthutha kanye Nesitoreji
Amashidi kufanele agcinwe endaweni lapho izinga lokushisa lingekho ngaphezu kuka-40℃, futhi abekwe avundlile phezu kwepuleti lombhede elinobude obungu-50mm noma ngaphezulu. Gcina kude nomlilo, ukushisa (imishini yokushisisa) kanye nelanga eliqondile. Isikhathi sokugcina samashidi yizinyanga eziyi-18 kusukela ngosuku aphuma ngalo efekthri. Uma ubude besikhathi besitoreji bungaphezu kwezinyanga eziyi-18, umkhiqizo nawo ungasetshenziswa ngemva kokuhlolwa ukuthi ufanelekile.
Amazwana Nezinyathelo Zokuqaphela Isicelo
Isivinini esikhulu nokujula kokusika okuncane g kuzosetshenziswa lapho kwenziwa imishini ngenxa yokungabi namandla kwe-thermal conductivity yamashidi.
Ukukhanda nokusika lo mkhiqizo kuzokhipha uthuli oluningi nentuthu. Izinyathelo ezifanele kufanele zithathwe ukuqinisekisa ukuthi amazinga othuli angaphakathi kwemingcele eyamukelekayo phakathi nokusebenza. Kunconywa ukuthi kungene umoya wendawo kanye nokusebenzisa imaski yothuli/izinhlayiya.
Amashidi angaphansi komswakama ngemuva komshini, ukumbozwa kwe-insulating vanish kunconywa.
