Description
技术领域
本发明涉及一种滤芯的制备方法，具体是指一种富硒钛基水处理滤芯的制备方法。
背景技术
目前，饮用水净化大都是采用活性炭进行过滤净化的，由于活性炭呈粉末状，使用不便，而采用超高分子量聚乙烯粉料与活性炭粉末制备过滤器件具有加工方便、性能优异、使用寿命长、过滤效果好等优点。这种传统的活性炭滤芯中所含有的超高分子量聚乙烯粉料在烧结过程会出现部分分解甚至容易产生有毒物质。
另一方面，硒是人体必需的微量元素。硒参与合成人体内多种含硒酶和含硒蛋白。其中谷胱甘肽过氧化物酶，在生物体内催化氢过氧化物或脂质过氧化物转变为水或各种醇类，消除自由基对生物膜的攻击，保护生物膜免受氧化损伤；硒参与构成碘化甲状腺胺酸脱碘酶。硒能提高人体免疫，促进淋巴细胞的增殖及抗体和免疫球蛋白的合成。硒对结肠癌、皮肤癌、肝癌、乳腺癌等多种癌症具有明显的抑制和防护的作用，其在机体内的中间代谢产物甲基硒醇具有较强的抗癌活性。硒与维生素E、大蒜素、亚油酸、锗、锌等营养素具有协同抗氧化的功效，增加抗氧化活性。同时，硒具有减轻和缓解重金属毒性的作用。基于此，随着人们生活水平的提高，富硒水已经作为一种高档的保健饮用水而为广大市民所接受。
通过检索，中国专利申请号为201710648884.5公开了一种活性炭烧结富硒水处理滤芯的方法，该方法使得通过该滤芯的水分了硒元素，实现了富硒水的效果。但是该技术方案，虽然公开了富硒矿粉，而由于富硒矿粉非常复杂的混合物体系，在烧结过程中形成的滤芯会容易引入其他杂质，同时也会降低活性炭的净化能力，此外，其仍然采用的超高分子量聚乙烯，同样存在上述问题。
因此，综合此现有技术存在的问题，本发明人提出了本项发明创造。
发明内容
本发明的目的是为了克服现有技术存在的缺点和不足，而提供一种富硒钛基水处理滤芯的制备方法。
为实现上述目的，本发明的技术方案是包括以下步骤：
(1)将玻璃纤维粉和氧化硒粉过200目筛，然后将二者按照质量比1:1混合均匀，在搅拌状态下，将温度加热到玻璃纤维的玻璃化温度，使得混合粉体融合形成团状富硒玻璃块，让该团状富硒玻璃块进入到4度以下的低温水中，然后取出，使得团状富硒玻璃块上产生皲裂，利用粉碎机将该团状富硒玻璃块粉碎，形成玻璃包裹或黏连氧化硒的富硒玻璃粉体；
(2)将椰壳活性炭粉、富硒玻璃粉体、钛粉、碳酸氢钠粉均过200目筛，然后按照质量比为(10-20):(40-60):(10-20)：(6-7)加入到搅拌机中搅拌2小时，得到混合粉料，然后将该混合粉料加入到成型模具压制成型成滤芯坯件；
(3)将滤芯坯件整齐放入真空电炉中进行烧结热处理，烧结温度为320℃，烧结时间为100～150min，烧结过程中碳酸氢钠分解，形成气泡溢出，从而在滤芯坯件中形成微孔结构。
该滤芯为棒状或者管件结构。
本发明的有益效果是，
(1)环保卫生，没有采用传统的聚乙烯作为基体材料，而是采用钛与玻璃相互复合的结构作为基体材料，环保性好，且烧结过程中不会产生额外的有毒物质。
(2)虽然氧化硒具有非常好的生物吸收性，比起传统的直接从自然界开采的硒矿而言，氧化硒能够保障不会引入硒矿的其他杂质，但是氧化硒是一种易溶于水的物质，通过步骤(1)的将玻璃纤维粉和氧化硒粉相互结合形成富硒玻璃粉体，这种粉体中，玻璃相会包裹住氧化硒粉体，然后通过步骤(3)中的烧结，钛粉作为强化粉体与玻璃相再次融合黏接，而碳酸氢钠分解产生的二氧化碳会使得在滤芯内形成多孔结构，该多孔分布在包裹有氧化硒的玻璃相表面，从而形成微滤结构，该微滤结构加上活性炭的微滤结构，综合进行水处理，而且在水净化过程中，氧化硒会通过微滤的孔从玻璃相缓慢渗出到水中，由于微滤的结构，该氧化硒能与活性炭的过滤净化有效期保持相当的使用寿命，形成缓释的富硒水，另外，碳酸钠也会缓释进入水中，形成微碱性水，具有更佳的保健效果。
(3)钛基体材质的滤芯能够利用钛的生物抑制性，起到抑制细菌生长的作用，提高净化效果。
具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合实施例对本发明作进一步地详细描述。
实施例1
(1)将玻璃纤维粉和氧化硒粉过200目筛，然后将二者按照质量比1:1混合均匀，在搅拌状态下，将温度加热到玻璃纤维的玻璃化温度，使得混合粉体融合形成团状富硒玻璃块，让该团状富硒玻璃块进入到4度以下的低温水中，然后取出，使得团状富硒玻璃块上产生皲裂，利用粉碎机将该团状富硒玻璃块粉碎，形成玻璃包裹或黏连氧化硒的富硒玻璃粉体；
(2)将椰壳活性炭粉、富硒玻璃粉体、钛粉、碳酸氢钠粉均过200目筛，然后按照质量比为17:42:14：6加入到搅拌机中搅拌2小时，得到混合粉料，然后将该混合粉料加入到成型模具压制成型成滤芯坯件；该压制成型采用液压机作为动力，液压控制在2KN。
(3)将滤芯坯件整齐放入真空电炉中进行烧结热处理，烧结温度为320℃，烧结时间为100～150min，烧结过程中碳酸氢钠分解，形成气泡溢出，从而在滤芯坯件中形成微孔结构。
该滤芯为棒状或者管件结构。
以上所揭露的仅为本发明较佳实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
