一、環(huán)氧樹脂絕緣板產(chǎn)品介紹
   環(huán)氧樹脂絕緣板產(chǎn)品是用浸漬紙、棉布、玻璃布、浸漬酚醛、環(huán)氧樹脂，經(jīng)烘焙熱壓而成的硬質(zhì)板狀絕緣材料。環(huán)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(huán)氧酚醛樹脂絕緣板適用于要求較高的電工機械、電器設(shè)備中作絕緣結(jié)構(gòu)件，并可在潮濕環(huán)境和變壓器中使用，耐熱等級為B級。

二、環(huán)氧樹脂絕緣板產(chǎn)品技術(shù)要求
1、環(huán)氧樹脂絕緣板外觀、表面應(yīng)平整光滑，不允許有雜質(zhì)和其他明顯的缺陷，允許有輕微的擦傷，邊緣應(yīng)切割整齊，端面不得有分層和裂紋。
2、環(huán)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(guī)格，可同供需雙方協(xié)議生產(chǎn)。其它數(shù)據(jù)詳見機電部標準。
3、環(huán)氧樹脂絕緣板產(chǎn)品可根用戶要求，加工成各種規(guī)格板、管、墊、法蘭、瓦、等異形件。

三、黃色環(huán)氧板技術(shù)參數(shù)

1、外觀 表面應(yīng)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(shù)平均值是介于表中兩厚度之間，則其指標值應(yīng)從內(nèi)插法求得。2如果測得的厚度算術(shù)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(shù)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(yīng)從單面加工至22.5mm且加工面應(yīng)是比較光滑的。
  3240環(huán)氧板是由電工用無堿玻璃纖維布浸以環(huán)氧酚醛樹脂，經(jīng)烘焙、熱壓而成。
  3240環(huán)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(huán)氧板適用于電機、電器設(shè)備中作為絕緣結(jié)構(gòu)零部件，并可在潮溫環(huán)境和變壓器油中使用。
  324環(huán)氧板以較高的機械性能和電氣性能，廣泛應(yīng)用在發(fā)電機、馬達、電子器具上作為絕緣材料和構(gòu)件。在變壓器油壓環(huán)境和濕度環(huán)境中也非常適用。

7、環(huán)氧樹脂和所用的固化劑的反應(yīng)是通過直接加成反應(yīng)或樹脂分子中環(huán)氧基的開環(huán)聚合反應(yīng)來進行的，沒有水或其它揮發(fā)性副產(chǎn)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%）。
