font-size: 16px;">　　1.電熱管電阻絲材質(zhì)硬度不均勻</span></p><p style="line-height: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　由于電阻絲材質(zhì)硬度不均勻，產(chǎn)生繞成的電熱絲拉伸后螺旋間距的不均勻。這種情況一般發(fā)生在拉制的電熱絲采用井式退貨的工藝中。繞制螺旋電熱絲時(shí)，的拉力不均勻也可以影響螺旋間距之間的不均勻。</span></p><p style="line-height: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　2.電熱管電阻絲設(shè)計(jì)不當(dāng)</span></p><p style="line-height: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　一般電熱管中的電熱絲都設(shè)計(jì)成螺旋狀，即彈簧狀。如果繞絲芯桿的直徑D與電熱絲直徑d比例是D/d＞8，在加粉時(shí)就會(huì)產(chǎn)生下垂現(xiàn)象，這是電熱絲圈距則是上稀下密。</span></p><p style="line-height: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　3.電熱管工藝操作不恰當(dāng)</span></p><p style="line-height: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　在加粉時(shí)引出棒外露不符合要求，太短時(shí)就邊振動(dòng)邊加粉邊敲管子邊將電熱絲引出棒拉長(zhǎng)，或太長(zhǎng)時(shí)就邊振動(dòng)邊加粉邊敲管子邊壓引出棒。這樣做造成電熱絲局部過(guò)稀或者局部過(guò)密甚至電熱絲圈與圈短路?？s管工藝操作不當(dāng)也會(huì)影響電熱絲分布的均勻性。</span></p><p style="line-height: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　4.電熱管加粉設(shè)備有缺陷</span></p><p style="line-height: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei"; font-size: 16px;">　　例如加分設(shè)備振幅不穩(wěn)，導(dǎo)棒提升速度不均勻，漏粉速度有快有慢等等。即使各種參數(shù)都正常，氧化鎂粉也是上稀下密。</span></p><p style="line-height: 2em;"><span style="font-family: 微軟雅黑, "Microsoft YaHei";
