Description

玻璃纤维短切毡的生产工艺
技术领域
本发明涉及一种玻璃纤维短切毡的生产工艺。
背景技术
玻璃纤维短切原丝毡是由玻璃纤维原丝短切成一定长度的短切纤维，用粉剂或乳液粘接剂粘接而成增强玻璃纤维制品。主要用于用手糊成型、缠绕成型、模压成型、机械成型等玻璃钢成型工艺。目前的玻璃纤维短切原丝毡工艺流程包括上丝、短切、施胶、收卷和包装等，存在乳剂或粉剂喷洒不均匀、玻璃纤维短切原丝毡水分高、乳剂粘网等缺点。
发明内容
本发明提供一种具有可以提高产品质量，降低成本优点的玻璃纤维短切毡的生产工艺。
本发明的技术方案是：一种玻璃纤维短切毡的生产工艺，所述的玻璃纤维短切毡的生产工艺：（1）分丝：无碱玻璃纤维连续原丝纱线，均匀分股纱束；
（2）成网：经过分丝的无碱玻璃纤维长丝利用抽风引力使其均匀分布，落至传送网带上铺置成网；
（3）针刺：采用花纹针刺机，经过滚轴冷压成型处理，其中花纹针刺机的植针密度3000-3560枚/m²，针刺频率800-1500r/min,管径为25-500mm；
（4）排湿烘干：经过烘箱加温排湿烘干后，使纤维与粘接剂彻底结合；
（5）收卷、包装：收卷后，采用大于毡卷的聚乙烯塑料进行包扎，如短切毡幅宽为1040MM，外箱尺寸为：长28CM×宽28CM×高1070CM，产品应垂直或水平放置。
在本发明一个较佳实施例中，所述烘箱的温度为 120-130℃。
在本发明一个较佳实施例中，所述无碱玻璃纤维直径为13μm。
本发明的一种玻璃纤维短切毡的生产工艺，具有可以提高产品质量，降低成本的优点。
具体实施方式
下面对本发明的较佳实施例进行详细阐述，以使本发明的优点和特征能更易于被本领域技术人员理解，从而对本发明的保护范围做出更为清楚明确的界定。
其中，所述的玻璃纤维短切毡的生产工艺：（1）分丝：无碱玻璃纤维连续原丝纱线，均匀分股纱束；
（2）成网：经过分丝的无碱玻璃纤维长丝利用抽风引力使其均匀分布，落至传送网带上铺置成网；
（3）针刺：采用花纹针刺机，经过滚轴冷压成型处理，其中花纹针刺机的植针密度3000-3560枚/m²，针刺频率800-1500r/min,管径为25-500mm；
（4）排湿烘干：经过烘箱加温排湿烘干后，使纤维与粘接剂彻底结合；
（5）收卷、包装：收卷后，采用大于毡卷的聚乙烯塑料进行包扎，如短切毡幅宽为1040MM，外箱尺寸为：长28CM×宽28CM×高1070CM，产品应垂直或水平放置。
进一步说明，所述烘箱的温度为 120-130℃，所述无碱玻璃纤维直径为13μm。
在进一步说明，花纹针刺机工作时，芯轴固定不转，其带孔根部为针刺区域，工作时刺针插入小孔。芯轴两侧的回转罗拉靠摩擦带动芯轴上的纤维管运动，由于芯轴中部螺纹的导向作用，纤维管向外输出。纤维管向外输出的同时，纤网不断输入针刺区域，随纤维管的回转缠绕在芯轴上，并得到针刺加固。可以看出，纤维管长度不受限制。采用叉形针和栅格托网板（栅格距3、3.5、4.7mm三种），可以使纤网获得毛圈状的表面效果。圆截面的叉形针头端开叉，穿刺经过预针刺的纤网时，叉取一束纤维穿出纤网，并形成毛圈结构。圈绒的清晰度和针刺密度有关，高度由针刺深度来控制，圆绒形状的大小根据栅板隔距确定。花纹针刺加工时采用较粗长化纤。进入花纹针刺机以前预针刺的密度通常为70-150刺/cm²。本发明提供一种玻璃纤维短切毡的生产工艺，具有可以提高产品质量，降低成本的优点。
本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本领域的技术人员在本发明所揭露的技术范围内，可不经过创造性劳动想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书所限定的保护范围为准。
