具体实施方式
以下结合附图说明及具体实施方式对本发明作进一步的详细描述:
砂带原纸主要采用60%的漂折木桨和40%的硫酸盐本色本桨为主要原材料制造,本发明的木桨采购主要是云南云景股份有限公司生产的丝茅松桨板。
砂在原纸的制造流程为:
木桨→碎解分离→筛选净化→浓缩储存→磨桨叩解→配料→抄造→分切复卷 →打包入库。纸页的抄造过程:造纸机由湿部和干部两部分组成,湿部包括流浆箱(即头箱)、网部和压榨部;干部包括干燥部、压光部和卷纸机。
参见图1,是本发明的造纸用湿部施胶装置示意图,造纸用网部包括伏辊4和成形园网1,伏辊4和成形园网1共同构成成形辊组,一般网部共有成辊形组3~5对,湿纸页在经成形辊组时主要是进行脱水和成型。
在成形辊组之间湿纸页2的下面设有喷施胶装置3,该装置由多个向上喷胶的喷嘴,多个喷嘴水平放置且放置方向和湿纸页移动方向垂直;喷施胶装置3下面可设有回收装置。
喷施胶装置3喷涂胶主要是2%的丁苯。
因喷嘴为现在技术本发明不一一描述。
图1 所示,在网部的尾部的湿纸页2运行 下方可通过支架设置一对红外探头5,一个探头用于发射红外线光源,另一个接收湿纸页2 反射后的红外线光源,并与计算机装置进行连接 ; 湿纸页2在网部的成形辊上传输。在检测时,首先会在计算机中设置好标准湿纸页样所反射的光线的值。
在生产时,当成形辊的湿纸页2通过红外探头5 下方时,红外探头5同时会搜集到湿纸页表面反射的光线的量,然后输出相应的感应信号,计算机依据感应信号确定识别参数检测值,依据识别参数检测值计算出湿纸页的涂膜厚度,再将计算出的湿纸页的涂膜厚度与计算机中的预设值 进行比较,当差值超过一定范围时,即判定为不合格,当差值在预设的范围内时,即为合格 产品。
对于不合格的产品,将发出预警信号,机台操作人员收到信号后,及时调整机器参数。
参见图2的压榨部B,压榨部分为压榨区和反压榨区,单面浸渍施胶装置置于压榨区和反压榨区之间,湿纸页经压榨上辊7和压榨下辊8之间通过进行压榨;浸渍施胶装置包括浸渍机架9,浸渍机架9的上端通过辊座连接有单面浸渍施胶辊601,单面浸渍施胶辊601的下侧设有单面浸渍胶槽602,单面浸渍施胶辊601上部置于压榨后的湿纸页2的下部进行涂胶,单面浸渍施胶辊601的下部浸于胶面603之下。
单面浸渍胶槽602的胶液为5‰MF(三聚氰胺甲基树脂)。
参见图3位于烘干部,一对浸渍施胶辊10将纸页2导入浸渍胶槽11的胶液内内,其中浸渍胶槽11的胶液为1%的丁苯、5‰甲基纤维素、1%聚乙烯丙酸树脂和0.5%聚乙烯醇的混合物。
参见图4,网部涂喷施胶装置包括吸膜泵302、储存槽303、气罐304、过滤网305、溶解槽306和若干个喷嘴301;溶解槽306把胶料溶解,胶料经过滤网305过滤后进入储存槽303;储存槽303内的胶料经气罐304加压后由吸膜泵302抽吸到若干个喷嘴301;
若干个喷嘴301且并列水平设置,涂喷施胶装置的施胶管上还设有调节阀。
聚酯编织干网按种类划分,可分为一层半干网、双层干网、扁丝干网、双径扁丝干网及特种材质编织干网(平网)。
本发明的计算机应具有的功能如本背景的计算出膜层的厚度的步骤等相类似,网部喷胶装置和压榨部浸渍施胶装置都设有施胶回流装置也就是回收装置;本申请在此作为现有技术不必一一描述。
本发明和普通的涂喷装置和涂胶量相比,能显著提高纸的质量,并能提高纸桨的利用率;主要是下面涂胶使得涂胶量少。
一、网部喷胶的优点(丁苯)
1、解决分层现象,增加层间结合力30%,同时增加纸板物理抗张强度40%;
2、解决渗透物理过程,使产品双面性能可以不一致,为后续一面适印刷,一面适用静电置砂提供保证;
3、对纸张与纸板抗静电、抗卷曲提供条件,同时减少用胶量。
二、压榨部单面浸胶的作用(MF)
1、解决纸张单面不透油,纸张具备单面浸渍的作用;
2、湿纸页更容易适应静电置砂。
三、烘干部半干表胶
1、使纸张整体加强防渗透,防静电;
2、增加纸张表面张力,提高纸张物理强度。
四、 桨内施胶
1、解决整体纤维弹性,同时增加纤维粘结力;提高物理强度;
2、防止纸张渗透静电产生,为后续工艺提供保证。

砂带原纸主要采用60%的漂折木桨和40%的硫酸盐本色本桨为主要原材料;(加入原料比例)
木桨→碎解分离→筛选净化→浓缩储存→磨桨叩解→配料→抄造→分切复卷 →打包入库。
