Description

一种复合平板筛网制作工艺
技术领域
本发明涉及筛网领域,尤其涉及一种复合平板筛网制作工艺。
背景技术
复合框架筛网由框架和滤网组成,目前的筛网加工工艺是将滤网用粘结剂固定于框架表面,使用粘结剂固定的网面粘结部分较易磨损,导致滤网翘起或脱落,影响筛网使用效果,所以现今的筛网使用寿命不长且筛网的网面不平整,在恶劣的环境下使用达不到应有的效果。
发明内容
根据以上技术问题,本发明提供一种复合平板筛网制作工艺,其特征在于包括以下步骤:
步骤一:根据要求先对筛网样式进行设计,然后进行模板制作;
步骤二:根据模板选取方形钢管或扁钢,将方形钢管或扁钢根据模板样式焊接成框架结构;
步骤三:对步骤二中成型的框架结构进行注塑处理,注塑处理过程中选取的注塑材料按照改性材料70-80%,玻璃纤维15%-35%的比例配制,配制完成后将注塑材料粉末注入成型的框架结构中,框架完成;
步骤四:进行滤网制作,根据框架尺寸裁剪滤网,滤网裁剪完成备用;
步骤五:将注塑后的框架结构和滤网结构置于热熔机上进行热熔处理,热熔处理用温度200-245℃,时间70-85s,常压1.0Pa;
步骤六:将步骤五中热熔处理后的框架结构和滤网置于常温下固化60-80s,然后将固定好的滤网进行毛边修理。
所述改性材料为PP8303。
所述改性材料为PP7726。
所述玻璃纤维为15%玻璃纤维。
所述改性材料为PP8303和PP7726混合。
所述改性材料和15%玻璃纤维质量比为30-80%:60-20%。
本发明的有益效果为:本申请通过热熔处理方式将滤网和框架固定在一起,避免了胶水的使用,无形中提高了本发明的使用寿命。本申请将改性PP8303、PP7726和15%玻璃纤维混合,增强了筛网的强度和任性。本发明的复合筛网具有结构简单的优点;本发明的复合筛网使用寿命长,延长了筛网的更换周期,降低了生产企业的停车维护成本;利用本发明复合筛网的张弛筛对高强度物料筛分能力有了很大提高。
