以每一份的重量为1g计,称量70g矿化滤料(即混合之后的主料);辅料:活性炭100g,粘结剂30g。
将70g矿化滤料、100g活性炭和30g粘结剂混合均匀,得到混合料。
将混合料放入磨具中,在100℃烧结60min,烧结压力为12MPa,将烧结好的富锶偏硅酸炭棒冷却后装入滤壳中,即得到矿化滤芯。
实施例二

将60g矿化滤料、120g活性炭和45g粘结剂混合均匀,得到混合料。
将混合料放入磨具中,在160℃烧结20min,烧结压力为18MPa,将烧结好的富锶偏硅酸炭棒冷却后装入滤壳中,即得到矿化滤芯。
实施例三
称量如下原料:
以每一份的重量为1g计,主料:改性白云岩15g,改性麦饭石3g,改性辉石17g,改性沸石10g,改性硅灰石6g;辅料:活性炭110g,粘结剂40g。
将称量得到的15g改性白云岩、3g改性麦饭石、17g改性辉石、10g改性沸石和6g改性硅灰石按照密度由小到大的顺序依次与110g活性炭和40g粘结剂进行混合,得到混合料。例如,先将细颗粒、密度小的改 性白云岩与活性炭和粘结剂进行混合,再将改性沸石、改性麦饭石、改性辉石和改性硅灰石依次与活性炭和粘结剂进行混合。当然,在实际添加原料的过程中,如果两个原料的密度比较接近,也可以根据原料的目数确定添加的顺序,例如先添加目数小的,再添加目数大的。
将混合料放入磨具中,在140℃烧结40min,烧结压力为16MPa,将烧结好的富锶偏硅酸炭棒冷却后装入滤壳中,即得到矿化滤芯。
需要说明的是,上述列举的三个实施例中的原料的重量份配比指示示例性地,本领域技术人员在实际应用中可以根据实际的水质需求等灵活地调整和设置原料的重量份配比,并根据原料的重量份配比相应地调整烧结温度、烧结时间和烧结压力。
进一步地,对通过上述方法制备得到的矿化滤芯进行了性能测试,详见表1和表2。表1实验方法为:在15℃进行通水测试,通水时,纯水流速为2.0L/min,当通水量达到800L、3000L、4000L时取250ml水样后关掉纯水机,30min后打开纯水机取500ml水样进行测试。
表2实验方法为:在20℃进行通水测试,通水时,纯水流速为1.5L/min,当通水量达到1000L、2000L、3000L和4000L时取250ml水样进行测试。
从表1和表2中可以看出,在进水为纯水情况下,在4000L通水量的条件下,偏硅酸、锶元素仍然能够进行稳定析出,且衰减速度较慢,即该矿化滤芯过滤后的富含丰富的偏硅酸、锶等有益的矿物质,达到了国家饮用水标准。
