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(qiáng)度與材料的厚度是沒有關(guān)系的。當(dāng)絕緣材料較厚時(shí)，會增加材料的壓力，導(dǎo)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(dāng)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(dāng)所處環(huán)境含有較重的水分時(shí)，電氣強(qiáng)度也會有所降低。上海偉奮實(shí)業(yè)有限公司 </p><p> 絕緣板主要用在配電房、配電所，用于配電設(shè)施地面的鋪設(shè)，絕緣板是泛指分子中含有兩個(gè)或兩個(gè)以上環(huán)氧基團(tuán)的有機(jī)高分子化合物，除個(gè)別外，它們的相對分子質(zhì)量都不高。環(huán)氧樹脂的分子結(jié)構(gòu)是以分子鏈中含有活潑的環(huán)氧基團(tuán)為其特征，環(huán)氧基團(tuán)可以位于分子鏈的末端、中間或成環(huán)狀結(jié)構(gòu)。由于分子結(jié)構(gòu)中含有活潑的環(huán)氧基團(tuán)，使它們可與多種類型的固化劑發(fā)生交聯(lián)反應(yīng)而形成不溶、不熔的具有三向網(wǎng)狀結(jié)構(gòu)的高聚物。

style="text-indent:25px">上海偉奮實(shí)業(yè)有限公司為您提供環(huán)氧板，期待您的光臨！上海fr4環(huán)氧板棒</p><p> 熱壓法： </p> <p> <br /> </p> <p> 絕緣板加工,將有機(jī)玻璃絕緣板加熱后，在模具中熱壓成型。這種造型法制成的工藝品形體飽滿，曲線流通，立體感強(qiáng)，有浮雕的作用。熱壓模可用木材、油泥塑形，然后用鑄鉛、3lian素材，石膏材料作陰陽模，有機(jī)玻璃加熱后即可壓成型。 </p> <p> <br /> </p> <p> 斷磨法： </p> <p> <br /> </p> <p> 絕緣板加工,將板形有機(jī)玻璃重疊粘貼在一起，?？趹粜湍Ｐ?，然后直接削磨斷面成型。此法制成的有機(jī)玻璃工藝品能得到色澤多變，渾樸自然的作用。 </p> <p> <br /> </p> <p> 鑲嵌法： </p> <p> <br /> </p> <p> 絕緣板加工,將不同色彩的有機(jī)玻璃塊切割成咱們所需求的幾何圖形，在底板上鑲嵌拼接而成。這種辦法要求拼接嚴(yán)密，棱角清楚，這樣能夠得到色彩強(qiáng)烈而又渾然一體的作用。 </p> <p> <br /> </p> <p>
