Description
技术领域
本发明涉及文具领域,尤其涉及一种千万用学习本。
背景技术
在现代社会中人们日常生活离不开纸张的使用,但是造纸工业在生产中产生的废水、废气、废渣、毒性物及噪声等会对环境造成严重污染,其中尤以水污染最为严重。造纸工业用、排水量大,一般每吨浆和纸约用水300吨以上。废水中有机物含量高,生化需氧量(BOD)高,悬浮物(SS)多,并含有毒性物,带色有异味,危害水生生物的正常生长,影响工农畜牧业和居民用水与环境景观。长年积累,悬浮物会淤塞河床港口,并产生硫化氢有毒臭气,危害深远。
如何在充分利用资源,保护生态环境的前提下,给造纸企业带来效益,是值得深思的问题,因此对于纸张的循环再造成为现今的一大课题。环保纸即是利用回收的废纸,经过适当的处理之后重新制造的纸张。循环再造纸工艺的确可以节约资源,减少耗能。但是若能从使用者手中使用时就开始循环利用纸张,那无疑将是一件零耗能的新型环保方式。
发明内容

附图说明
下面结合附图和实施例对本发明进一步说明。
图1示出了本发明实施例提供的一种千万用学习本的结构示意图;
图2示出了本发明实施例提供的另一种千万用学习本的结构示意图。
图中,1.油膜纸层,2.书写用纸层,3.第一透气薄膜层,4.水刺无纺布层,5.第二透气薄膜层,6.硬纸板,7.凹槽,8.输入接口。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白,以下结合附图及实施例,对本发明进行进一步详细说明。应当理解,此处所描述的具体实施例仅用以解释本发明,并不限定本发明。
如图1所示,本发明实施例提供了一种千万用学习本,包括:可擦除纸张,该可擦除纸张包括油膜纸层1和书写用纸层2,油膜纸层1覆盖在书写用纸层2上。
油膜纸层的引入使本发明实施例有别于传统纸张,使该千万用学习本在书写后可以用普通介质擦除,在使用者手上实现循环利用,零能耗绿色环保。
在此基础上,进一步地:千万用学习本可以由多张可擦除纸张装订而成。
如图2所示,在上述任意实施例的基础上,进一步地,书写用纸层2的下方可以自上而下依次设置有第一透气薄膜层3、水刺无纺布层4和第二透气薄膜层5,其中水刺无纺布层4浸润有字迹消除液;字迹消除液由10~15重量份的乙醇、6~10重量份的丙酮、3~8重量份的草酸、20~30重量份的烷基酚聚氧乙烯醚、15~20重量份的聚氧乙烯脂肪醇醚、40~50重量份的水混合而成;第一透气薄膜层3和第二透气薄膜层5对应书写用纸层2的每个字格部位均设置有有多个透气孔,多个透气孔设置为圆形,该透气孔的孔径为0.05~0.15mm;第一透气薄膜层3和第二透气薄膜层5由40~50重量份的聚氯乙烯树脂、20~30重量份的环氧树脂、5~8重量份的淀粉制成,厚度为0.05~0.1mm;装订在一起的可擦除纸张的下方设置有预定厚度的硬纸板6,该硬纸板6对应书写用纸层2的每个字格部位均设置有凹槽7,凹槽7内设置有超声波振子,超声波振子与输入接口8电连接,输入接口8设置在硬纸板6上并在硬纸板6的侧面外露,该输入接口8与外部的超声波发生器相连。
在擦除千万用学习本时,输入接口8与外部的超声波发生器相连,通电后,超声波振子振动,水刺无纺布层4所浸润的字迹消除液在超声波的作用下保持振动,穿过第一透气薄膜层3和第二透气薄膜层5,破坏油膜层1上的字迹与油膜层1表面的吸附使其被驳离,从而达到更高的擦除效率。当油膜层1经多次擦除有所损坏时,字迹消除液依然可以穿过第一透气薄膜层3和第二透气薄膜层5,破坏书写用纸层2上的字迹与书写用纸层2表面的吸附使其被驳离,提高了普通介质的擦除效率。超声波振子等组件的引入,使该千万用学习本擦除起来更加便利,效率也更高。
在此基础上,进一步地,本发明实施例中,透气孔的孔径可以为0.1mm。如表1所示,发明人经过大量且复杂的对比试验同时发现,透气孔的孔径对学习本在超声波振子下的擦除效率有影响,在透气孔的孔径为0.1mm时,字迹消除液浸润纸张所需时间较短,擦除效率较高,且挥发时间较长,可以存放较长时间,这是现有技术所不曾披露的,也不是普通技术人员经过简单的试验就能够获得的,竭尽了发明人的心血,是发明人付出了大量试验的劳动成果。
表1字迹消除液浸润纸张所需时间、未使用状态下的挥发时间与透气孔的孔径的关系
在上述任意实施例的基础上,本发明对超声波振子的类型不做限定,优选的,超声波振子可以为磁致伸缩式振子。磁致伸缩式振子的使用寿命很长,操作也十分安全。
或者,进一步地,超声波振子可以为压电陶瓷式振子。在实际使用过程当中,相对于较为昂贵的磁致伸缩式振子,压电陶瓷式振子更为国内外众多的超声波设备生产厂家所青睐,与磁致伸缩式振子相比,其工作效率也更高,因此在超声波清洗设备制造领域得到广泛的使用。
在此基础上,进一步地,压电陶瓷式振子的间距为5~10mm。如表2所示,发明人经过大量且复杂的对比试验同时发现,压电陶瓷式振子的间距对学习本在超声波振子下的擦除效率有影响,间距过宽会使振动方向偏离,过窄也会加速腐蚀整个设备,缩短使用寿命。在压电陶瓷式振子的间距为5~10mm时,字迹消除液浸润纸张所需时间较短,擦除效率较高,同时其超声波振子的使用寿命也较长,这是现有技术所不曾披露的,也不是普通技术人员经过简单的试验就能够获得的,竭尽了发明人的心血,是发明人付出了大量试验的劳动成果。
表2字迹消除液浸润纸张所需时间、未使用状态下的挥发时间与振子间距的关系
尽管本发明已进行了一定程度的描述,明显地,在不脱离本发明的精神和范围的条件下,可进行各个条件的适当变化。可以理解,本发明不限于所述实施方案,而归于权利要求的范围,其包括所述每个因素的等同替换。
