一、環氧樹脂絕緣板產品介紹
   環氧樹脂絕緣板產品是用浸漬紙、棉布、玻璃布、浸漬酚醛、環氧樹脂，經烘焙熱壓而成的硬質板狀絕緣材料。環氧酚醛樹脂絕緣板具有較高的機械強度、介電性能、耐油性和耐腐蝕性，環氧酚醛樹脂絕緣板適用于要求較高的電工機械、電器設備中作絕緣結構件，并可在潮濕環境和變壓器中使用，耐熱等級為B級。

二、環氧樹脂絕緣板產品技術要求
1、環氧樹脂絕緣板外觀、表面應平整光滑，不允許有雜質和其他明顯的缺陷，允許有輕微的擦傷，邊緣應切割整齊，端面不得有分層和裂紋。
2、環氧樹脂絕緣板尺寸：面積不得小于380×480平方毫米，如需特殊規格，可同供需雙方協議生產。其它數據詳見機電部標準。
3、環氧樹脂絕緣板產品可根用戶要求，加工成各種規格板、管、墊、法蘭、瓦、等異形件。

三、黃色環氧板技術參數

1、外觀 表面應平滑，無氣泡、皺紋和裂紋。
2、標稱厚度及允許偏差見表1。

注：1如果測得的試樣厚度算術平均值是介于表中兩厚度之間，則其指標值應從內插法求得。2如果測得的厚度算術平均值小于0.4mm，則其指標值取≤17mg。如果標稱厚度為25mm并測得的厚度算術平均值大于25mm時，則其指標值取≤61mg。標稱厚度大于25mm的板材，則應從單面加工至22.5mm且加工面應是比較光滑的。
  3240環氧板是由電工用無堿玻璃纖維布浸以環氧酚醛樹脂，經烘焙、熱壓而成。
  3240環氧板具有較高的機械和介電性能，較好的耐熱性和耐潮性，并有良好的機械加工性，耐熱等級為B級。
  3240環氧板適用于電機、電器設備中作為絕緣結構零部件，并可在潮溫環境和變壓器油中使用。
  324環氧板以較高的機械性能和電氣性能，廣泛應用在發電機、馬達、電子器具上作為絕緣材料和構件。在變壓器油壓環境和濕度環境中也非常適用。

7、環氧樹脂和所用的固化劑的反應是通過直接加成反應或樹脂分子中環氧基的開環聚合反應來進行的，沒有水或其它揮發性副產物放出。它們和不飽和聚酯樹脂、酚醛樹脂相比，在固化過程中顯示出很低的收縮性（小于2%）。
