style="text-indent:25px">EVA材料是乙烯-醋酸乙烯共聚物，一般醋酸乙烯(VA)含量在5%～40%。與聚乙烯相比，EVA由于在分子鏈中引入了醋酸乙烯單體，從而降低了高結(jié)晶度，提高了柔韌性、抗沖擊性、填料相溶性和熱密封性能，被應(yīng)用于發(fā)泡鞋料、功能性棚膜、包裝膜、熱熔膠、電線電纜及玩具等領(lǐng)域。一般來(lái)說(shuō)，EVA樹脂的性能主要取決于分子鏈上醋酸乙烯的含量。隨著我國(guó)制鞋工業(yè)的發(fā)展以及功能棚膜用量的增加，我國(guó)對(duì)EVA樹脂的需求量還將逐年增加。EVA材料比PE的性能改善，主要是彈性、柔性、光澤性、透氣性等方面，另外，它的耐環(huán)境應(yīng)力開裂性得到了提高，對(duì)填料的受容性增大，可以采用加入較多增強(qiáng)填料的方法來(lái)避免或減少EVA力學(xué)性能下降。</p><p style="text-indent:25px">很多人有這樣的疑問，EVA是環(huán)保材料嗎，答案EVA本來(lái)就是環(huán)保材料，但是是有分別的，發(fā)泡材料，A料和B料是環(huán)保的，用全新料發(fā)泡而成。EVA是烯-醋酸烯共聚物，這兩種合成物質(zhì)，都是環(huán)保的。EVA樹脂是無(wú)污染、無(wú)味的透明塑料顆粒。如果EVA是塑料成品，EV**材之類的，環(huán)保于否，就要看生產(chǎn)廠家生產(chǎn)時(shí)是否有用其他的不環(huán)保原料一起生產(chǎn)。如果單用EVA樹脂生產(chǎn)，那么一定是環(huán)保的。EVA本身屬于無(wú)害的，屬于環(huán)保材料。隨著我國(guó)制鞋工業(yè)的發(fā)展以及功能棚膜用量的增加，我國(guó)對(duì)EVA的需求量還將逐年增加。</p><div

EVA沖壓模切過程中，最常見的問題莫過于斜邊，斜邊對(duì)產(chǎn)品有哪些影響？首先是影響外邊框厚薄不均，一款外框厚薄不均的產(chǎn)品，嚴(yán)格來(lái)講，是不合格產(chǎn)品。作為內(nèi)襯厚薄不均，產(chǎn)品強(qiáng)度**降低，使用壽命縮短;尺寸精細(xì)度下降，影響到產(chǎn)品美觀，甚至嚴(yán)重偏離設(shè)計(jì)要求，影響產(chǎn)品使用。 </p> <p> 導(dǎo)致此種問題產(chǎn)生的原因在于：泡棉厚度太厚，高刀在沖切過程中，泡棉擠壓后沖切，泡棉帶面擠壓形成的斜邊 </p> <p> 我們常用的解決辦法有兩種：一是從刀具上想辦法，常用的刀具是雙斜邊刀具，這種刀沖壓模切EVA對(duì)材料擠壓大，易造成斜邊，我們的經(jīng)驗(yàn)是改雙斜刀為<span style="color:#E53333;">單鋒刀</span>，外斜內(nèi)直，能**減少斜邊的產(chǎn)生。 </p> <p> <br /> 四川環(huán)保EVA批發(fā)</p><p style="text-indent:25px">四川環(huán)保EVA批發(fā)</p><p
