Description

一种单面膜平板陶瓷过滤膜片的制备方法
技术领域
本发明涉及过滤膜片的制备方法,特别涉及一种单面膜平板陶瓷过滤膜片的制备方法。
背景技术
陶瓷过滤膜由于化学稳定性好,耐酸碱耐腐蚀性强,刚性和强度好,优异的亲水性,寿命长等优点成为液、气分离处理最有发展前途的品种之一。传统陶瓷过滤膜多采用的是中空膜载体通过浸渍凃膜,溶胶凝胶,或化学气相淀积过程,再经过重复煅烧获得过滤膜。中空膜载体的制备工艺复杂,成型难度较大,导致成品率不高,难以制作大尺寸规格。膜层的生产由于需要重复煅烧,不仅增加了加工难度,提高了能耗,而且降低了成品率。
发明内容
为了解决上述问题,本发明提供一种容易制备的单面膜平板陶瓷过滤膜片的制备方法。
本发明中的一种单面膜平板陶瓷过滤膜片的制备方法,包括以下步骤:
S1:制作成型的平板薄胚体;
S2:将制成的平板薄胚体移至喷淋系统下:
S3:通过喷淋系统在平板薄胚体的表面形成薄薄的膜层;
S4:将喷淋过的平面薄胚体送入煅烧装置中;
S5:煅烧成型,生成在疏松的载体单面具有致密微孔的膜片。
上述方案中,所述S1中通过挤出成型制成平面薄胚体。
上述方案中,所述S1中通过压制成型制成平面薄胚体。
本发明的优点和有益效果在于:本发明提供一种单面膜平板陶瓷过滤膜片的制备方法。本发明制备工艺简单,成型难度较小,成品率高,方便制作大尺寸规格。膜层的生产由于不需要重复煅烧,不仅降低了加工难度,减少了能耗,而且提高了成品率。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本发明的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动性的前提下,还可以根据这些附图获得其他的附图。
图1为本发明的流程示意图。
具体实施方式
下面结合附图和实施例,对本发明的具体实施方式作进一步描述。以下实施例仅用于更加清楚地说明本发明的技术方案,而不能以此来限制本发明的保护范围。
如图1所示,本发明是一种单面膜平板陶瓷过滤膜片的制备方法,包括以下步骤:
S1:制作成型的平板薄胚体;
S2:将制成的平板薄胚体移至喷淋系统下:
S3:通过喷淋系统在平板薄胚体的表面形成薄薄的膜层;
S4:将喷淋过的平面薄胚体送入煅烧装置中;
S5:煅烧成型,生成在疏松的载体单面具有致密微孔的膜片。
上述方案中,S1中通过挤出成型或压制成型制成平面薄胚体。
在现有的工艺中,在胚体成型之后,进行一次烧制,然后涂膜。由于两面都需要涂膜,而胚体是软的,无法在烧制前反转,所以必须烧制两次。原有工艺中,两面膜之间的连接点较多,导致损失的有效过滤面积也多。本发明为一种单面膜平板陶瓷过滤膜片的制备方法。本发明制备工艺简单,成型难度较小,成品率高,方便制作大尺寸规格。膜层的生产由于不需要重复煅烧,不仅降低了加工难度,减少了能耗,而且提高了成品率。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
