参见图3,吸附剂180的制造方法可以包括制造基底吸附物质1820和基底树脂物质1840的步骤S120、混合基底吸附物质1820和基底树脂物质1840的骤S140及制造具有薄膜形态的吸附剂的步骤S160。
在制造基底吸附物质1820和基底树脂物质1840的步骤S120中,可提供基底吸附物质1820及基底树脂物质1840。
基底吸附物质1820包含能够吸附气体的物质,可表示与基底树脂混合之前的吸附物质。基底吸附物质1820可以是用于提供吸附物质的物质。根据实施例,基底吸附物质1820可包含前面参见吸附物质说明的物质中任意一种。根据实施例,基底吸附物质1820可提供为粉末(powder)形态。提供为粉末形态的情况下,基底吸附物质1820的粒径(particlediameter)可以是0.1μm至10μm。但,并不必限定于前述数值范围,根据实施例,基底吸附物质1820的粒径可以是3μm至5μm。其中,基底吸附物质1820的粒径数值可表示包含于基底吸附物质1820的多个颗粒的平均尺寸。例如,“粒径”可表示目标物体中定义的最大直径。“粒径”可通过电子显微镜等确定,但本发明不限于此。实施例中,在图4示出作为基底吸附物质1820的例子的Y型沸石的照片。
基底树脂物质1840包含树脂,可表示与基底吸附物质1820混合之前的树脂。基底树脂物质1840可以是用于提供树脂物质的物质。根据实施例,基底树脂物质1840可包含前面参见树脂物质说明的物质中任意一种。根据实施例,图5中示出作为基底树脂物质1840的例子的聚丙烯树脂的照片图像。
根据实施例,基底吸附物质1820的直径与基底树脂物质1840的直径可以不同。
在混合基底吸附物质1820和基底树脂物质1840的步骤S140,可以混合基底吸附物质1820和基底树脂物质1840,以提供作为母料提供的吸附组合物1800。可提供具有母料形态的吸附组合物1800。根据实施例,图6中示出作为吸附组合物1800的例子的含Y型沸石和聚丙烯树脂的母料的照片图像。
在本步骤,可对基底吸附物质1820和基底树脂物质1840进行熔融共混(meltblending)工序。随着熔融共混工序的进行,基底吸附物质1820和基底树脂物质1840可彼此混合以作为吸附组合物1800提供。熔融共混工序可通过已知的多种熔融共混装置执行,对熔融共混装置不做特别限定。
在本步骤,基底吸附物质1820和基底树脂物质1840所混合的重量比率可满足预定数值范围。例如,相对于基底吸附物质1820和基底树脂物质1840的总重量的基底吸附物质1820的重量比率可以是5重量%至50重量%。或者,相对于基底吸附物质1820和基底树脂物质1840的总重量的基底吸附物质1820的重量比率可以是5重量%至30重量%。相对于基底吸附物质1820和基底树脂物质1840的总重量的基底吸附物质1820的重量比率可以是20重量%至30重量%。
关于执行熔融共混工序的温度,可以在公知的熔融共混工序温度范围中对基底吸附物质1820和基底树脂物质1840不产生热损伤的温度范围适当选择。
在本步骤,基底吸附物质1820和基底树脂物质1840可在分子尺度彼此混合。
根据实施例,在以薄膜形态提供之前,可先执行混合基底吸附物质1820和基底树脂物质1840的工序。因此,可根据工序用户的意图便于控制吸附剂180中吸附物质和树脂物质之间的比率。并且,基底吸附物质1820和基底树脂物质1840各自的粒径不同的情况下,也能够均匀混合基底吸附物质1820和基底树脂物质1840,从而使得吸附物质和树脂物质均匀分布在整个吸附剂180中。
在制造具有薄膜形态的吸附剂的步骤S160,可薄膜化提供的吸附组合物1800。
在本步骤,可薄膜化吸附组合物1800,以提供具有薄膜形态的吸附剂180。薄膜化工序可使用公知的薄膜化方法。例如,薄膜化工序可使用薄膜铸塑法、压延法、熔融制膜法等。优选地,可通过执行对吸附组合物1800的薄膜铸塑(film casting)工序提供具有薄膜形态的吸附剂180。根据实施例的具有薄膜形态的吸附剂180示于图7。
根据实施例,提供的吸附剂180的厚度可以是50μm以下。或者,提供的吸附剂180的厚度可以是30μm以下。为了调节吸附剂180的厚度,在薄膜化工序中,可将吸附剂180向表示工序进行方向的纵向(MD;machine direction)延伸。即,实验性地,延伸的过程中,可向吸附剂180提供纵向的外力,因吸附组合物1800的排列方向可能存在薄膜形态被损毁的顾虑。例如,调节吸附剂180的厚度的过程中可能向纵向撕裂,或发生卷曲(curl)。
但,用于制造吸附剂180的吸附组合物1800以母料提供,从而能够防止吸附剂180在薄膜化的过程中的物理损毁,因此能够实现提高工程性的效果。
薄膜铸塑工序可在预定温度范围内进行。例如,所述预定温度范围可以是200℃至240℃,但并非必须限定于此。例如,可在吸附组合物不会被热损伤的温度范围适当选择。
之后根据实施例,为了去除存在于具有薄膜形态的吸附剂180的水分,可执行真空干燥(vacuum dry)工序。所述真空干燥工序可在80℃至120℃范围的温度范围执行1小时。但,本发明并非必须限定于前述范围。
