id="kivkgv3" class="box"><p><p> 絕緣板的特點： </p> <p> 1、收縮性低。環(huán)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(huán)氧基的開環(huán)聚合反應來進行的，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%）。 </p> <p> 2、力學性能。固化后的環(huán)氧樹脂體系具有優(yōu)良的力學性能。 </p> <p> 3、形式多樣。各種樹脂、固化劑、改性劑體系幾乎可以適應各種應用對形式提出的要求，其范圍可以從極低的粘度到高熔點固體。 </p> <p> 4、粘附力強。環(huán)氧樹脂分子鏈中固有的極性羥基和醚鍵的存在，使其對各種物質(zhì)具有很高的粘附力。環(huán)氧樹脂固化時的收縮性低，產(chǎn)生的內(nèi)應力小，這也有助于提高粘附強度。 </p> <p> 5、固化方便，上海供應質(zhì)量環(huán)氧板廠家，上海供應質(zhì)量環(huán)氧板廠家。選用各種不同的固化劑，環(huán)氧樹脂體系幾乎可以在0～180℃溫度范圍內(nèi)固化，上海供應質(zhì)量環(huán)氧板廠家。上海偉奮實業(yè)有限公司是一家專業(yè)提供環(huán)氧板的公司，期待您的光臨！上海供應質(zhì)量環(huán)氧板廠家</p><div

</p> <p> <br /> </p><p> fr4環(huán)氧板溫度上升時為什么會加大電氣強度? </p> <p> 1、環(huán)氧板材料厚度：由于擊穿電壓與厚度成正比，而電氣強度與材料的厚度是沒有關(guān)系的。當絕緣材料較厚時，會增加材料的壓力，導致材料散熱困難、fr4環(huán)氧板出現(xiàn)氣泡等現(xiàn)象，從而降低絕緣材料的使用性能; </p> <p> 2、溫環(huán)氧板度和濕度：當絕緣材料所使用的區(qū)域，，fr4環(huán)氧板從而降低絕緣材料的使用性能。而當所處環(huán)境含有較重的水分時，電氣強度也會有所降低。上海偉奮實業(yè)有限公司環(huán)氧板，就選上海偉奮實業(yè)有限公司，用戶的信賴之選，歡迎您的來電哦！</p><div style="width:100%;text-align:

style="text-indent:25px">上海偉奮實業(yè)有限公司致力于提供環(huán)氧板，期待您的光臨！上海供應質(zhì)量環(huán)氧板廠家</p><p> 絕緣板的特點： </p> <p> <br /> </p> <p> 1、收縮性低。環(huán)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(huán)氧基的開環(huán)聚合反應來進行的，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%）。 </p> <p> <br /> </p> <p> 2、力學性能。固化后的環(huán)氧樹脂體系具有優(yōu)良的力學性能。 </p> <p> <br /> </p> <p> 3、形式多樣。各種樹脂、固化劑、改性劑體系幾乎可以適應各種應用對形式提出的要求，其范圍可以從極低的粘度到高熔點固體。 </p> <p> <br /> </p> <p> 4、粘附力強。環(huán)氧樹脂分子鏈中固有的極性羥基和醚鍵的存在，使其對各種物質(zhì)具有很高的粘附力。環(huán)氧樹脂固化時的收縮性低，產(chǎn)生的內(nèi)應力小，這也有助于提高粘附強度。 </p> <p> <br /> </p> <p> 5、固化方便。選用各種不同的固化劑，環(huán)氧樹脂體系幾乎可以在0～180℃溫度范圍內(nèi)固化。上海供應質(zhì)量環(huán)氧板廠家</p><p
