具体实施方式
可以通过如下工艺完成多孔陶瓷蜂窝体的制造:对陶瓷粉末批料混合物进行塑化,将混合物挤出通过蜂窝挤出模具以形成蜂窝挤出体,以及对挤出体进行切割、干燥和烧制以产生高的强度和热耐久性的陶瓷蜂窝体,其具有从第一端面轴向延伸到第二端面的通道。如本文所用,陶瓷蜂窝体包括陶瓷蜂窝整体件和区段式陶瓷蜂窝体。
共挤出的外表皮或后施涂的外表皮可以形成陶瓷蜂窝体的轴向外周表面。无论是整体式或者区段式,蜂窝体的每个通道都可以在入口面或出口面堵住,以产生过滤器。当留下一些通道未被堵住时,可以产生部分过滤器。无论是整体式或者区段式,蜂窝体都可以经催化以产生基材。此外,过滤器和部分过滤器可以被催化以提供多种功能性。由此产生的陶瓷蜂窝体被广泛地用作机动车废气系统的陶瓷催化剂载体,并且作为催化剂载体和壁流式颗粒过滤器从发动机废气去除烟炱和其他颗粒。
商业上成功的陶瓷蜂窝制造工艺是如下这些:它们采用大的同向旋转双螺杆挤出机用于混合和挤出陶瓷蜂窝挤出体。柱塞挤出、压制、浇铸、喷洒和3D打印是其他陶瓷蜂窝制造工艺。
用于多孔陶瓷蜂窝过滤器的堵塞工艺涉及:在端面处,将湿的胶合剂糊料推入蜂窝体的通道中,以形成湿堵塞物,以及然后在干燥器(例如,微波或热空气干燥器)中进行干燥。在生产过程中,在部件被堵塞住与部件到达干燥器的入口之间存在5-10分钟的明显时间延迟。在部件到达干燥器之前,干燥动力学倾向于驱使水进入多孔陶瓷蜂窝体通道壁中。这会导致湿堵塞物的收缩,会引起堵塞物的中心和顶部中的空穴或微凹陷。在这里,堵塞物的顶部指的是堵塞的蜂窝体端面处的外表面。相反地,如果将部件立即引导到干燥器,则立即对面进行加热。一旦面明显干燥,则堵塞胶合剂不会在发生移动和引起微凹陷。
但是,热空气干燥器与内部除水进入通道壁发生竞争,并且无法完全消除诸如微凹陷之类的缺陷。此外,将具有湿的堵塞物的部件立即插入干燥器中会是困难的,因为通常需要对部件进行检查,以及在堵塞与干燥之间存在其他步骤。
2008年11月25日提交的美国专利申请公开第2009/0140467号描述了一种采用经加热的夯锤(tamper)接触堵塞的端面的技术,其全文通过引用结合入本文。这描述了一种经加热的板材,在部件面被堵塞住之后压入其中,以减少诸如微凹陷之类的缺陷。但是,经加热的夯锤是额外的工艺步骤,其可能降低制造效率并且可能导致堵塞胶合剂收缩远离通道壁,导致漏光,在检查过程中,在堵塞的通道中的堵塞物附近或者穿过堵塞物检查到光。堵塞胶合剂收缩远离通道壁是与在堵塞物中形成内部空穴的相反现象,其中,堵塞胶合剂在堵塞胶合剂柱内部的一个或多个空气袋周围打开。
本公开的示例性实施方式提供了一种在用胶合剂堵塞住端面之后立即对端面进行非接触式加热的方法,从而使得多孔陶瓷蜂窝体的端面处的堵塞胶合剂快速干燥和变硬。本公开的示例性实施方式还提供了一种在用胶合剂堵塞住端面之后在不发生接触的情况下立即对端面进行加热的系统,从而使得蜂窝体的端面处的堵塞胶合剂快速干燥和变硬。如本文所用,术语“立即”和“立刻”指的是小于5分钟(例如,小于3分钟、小于2分钟、小于1分钟、小于30秒、小于20秒、小于15秒、小于5秒、或者甚至小于1秒)的时间延迟。根据这些示例性实施方式,提供了方法和系统,它们在干燥器之前,仅使得端面处的孔道通道中的堵塞胶合剂部分干燥,以减少和消除表面缺陷(包括例如,空穴和微凹陷)。在立即的非接触式干燥之后,可以在干燥器(例如,微波或热空气干燥器)中对堵塞的蜂窝体进行进一步干燥。
图1显示根据对比工艺的蜂窝体端面100在对胶合剂堵塞进行空气干燥之后的局部放大图。蜂窝体的端面100包括:交叉的多孔陶瓷壁110,其从端面100延伸以形成孔道通道120;以及在端面100处的一些通道120中的干燥的胶合剂堵塞物130。
如图1所示,用湿的胶合剂糊料(例如,2011年11月30日提交的美国转申请公开第2013/0136893号所述的冷凝固胶合剂糊料,其全文通过引用结合入本文)堵塞住部件,以及在环境条件下(例如,18℃至25℃的室温(RT)和10%至90%的相对湿度)使其空气干燥。从图1可以看出,结果是大的表面空穴(微凹陷)140。
湿胶合剂糊料的组成没有具体限制,表1提供了本文所用的一个例子。
表1
堵塞物湿胶合剂糊料的组成不一定有限制,并且可以包括例如:无机粉末、无机粘合剂、有机粘合剂、液体载剂、和添加剂(例如,表面活性剂、溶剂、非溶剂、润滑剂、成孔剂等)。
例如,无机粉末可以包括如下物质的颗粒:堇青石、熔融二氧化硅、硅酸盐、碳化硅、氧化铝、铝氧化物、钛酸铝、二氧化钛、镁、镁稳定化的氧化铝、钙稳定化的氧化铝、氧化锆、锆氧化物、氧化锆稳定化的氧化铝、钇稳定化的氧化锆、钙稳定化的氧化锆、锆多铝红柱石、多铝红柱石、尖晶石、氧化镁、氧化铌、二氧化铈、氮化物、碳化物等,或其任意组合。
在各种实施方式中,无机粘合剂可以是胶体,例如胶体二氧化硅。可以使用的其他无机粘合剂包括例如:坡缕石、天然粘土、膨润土、高岭土、或者基于纤维素的无机粘合剂。非限制性的无机粘合剂包括例如:胶态二氧化硅,例如,购自W.R.Grace&公司的Ludox HS(HS-40)、AS、和SK。非限制性的有机粘合剂可以包括例如:纤维素材料,如甲基纤维素,宽范围的各种胶,例如黄原胶和蘑菇粉(actigum);以及聚乙烯醇及其衍生物。考虑其他有机粘合剂可适用于堵塞胶合剂组合物,例如,羟丙基甲基纤维素以及其他甲基纤维素衍生物,和/或其任意组合。示例性的甲基纤维素粘合剂是MethocelTM A4M,购自美国密歇根州米德兰市的陶氏化学公司(Dow Chemical Company of Midland,Michigan,USA)。
根据某些实施方式,液体载剂可以是水,但是应理解的是,也可以使用相对于合适的有机粘合剂展现出溶剂作用的其他液体载剂。例如可以结合液体载剂从而为水性组合物提供可流动或糊状稠度,从而使得可以将水性组合物作为糊料或胶合剂施涂到蜂窝体。
图2显示根据第二种对比工艺的蜂窝体端面150在对与图1具有相同组成的胶合剂堵塞进行空气干燥之后的局部放大图。图2所示的部件以5-10分钟的最小时间延迟运输到干燥器。从图2可以看出,结果是大的表面空穴(微凹陷)140,但是质量略微好于图1所示的结果。
图3显示根据本公开示例性实施方式的蜂窝体端面200在对胶合剂堵塞物300进行干燥之后的局部放大图,其中,湿胶合剂糊料的组成与图1相同。蜂窝体的端面200包括:交叉的多孔陶瓷壁310的矩阵,其从端面200延伸以形成孔道通道320;以及在端面200处的一些通道320中的干燥的胶合剂堵塞物330。
图3所示的堵塞端面200显示在端面200的一些的通道320中用湿胶合剂进行了堵塞,以及加热2分钟,采用的是位置距离堵塞部件的端面200约1英寸(2.54cm)的热板,从而在堵塞面200处产生100℃区域,之后部件后续在75℃进行干燥。如所示,堵塞物330展现出光滑的不含缺陷的顶表面340,并且消除了表面空穴(微凹陷)。在这种情况下,向端面200施加非接触式加热,从而在堵塞之后的约20秒至30秒内开始进行干燥。
在图3所示的例子中,为了证实根据本公开示例性实施方式的堵塞质量的改进,使用热板来加热堵塞的端面200,但是本公开不限于此,以及可以在用湿胶合剂糊料进行堵塞过程之后立即使用其他热源来加热部件的端面200,例如,红外加热、激光加热、微波加热、和其他辐射加热技术,热空气和其他传导和对流技术等,及其组合。本文所用的传导加热指的是非接触式传导加热,例如,通过大气(例如,空气,如空气分子)传导加热部件的端面200。例如,在没有与堵塞的端面200发生接触的情况下加热堵塞的端面200的热板可以具有辐射加热组件、传导加热组件、和对流加热组件。
下面将参照图4、5和6描述根据本公开示例性实施方式的方法和系统。
方法包括对蜂窝体400进行堵塞。图4显示蜂窝体400在堵塞端面402的部分侧视示意图。蜂窝体400具有基本平行的纵向孔道404的阵列,其受到交叉壁410的矩阵的限定。孔道404在柱状体的相对端面之间延伸。孔道404受到交叉多孔陶瓷壁410的矩阵的限定。孔道404和壁410受到表皮的限定,其可以具有圆形、椭圆形或者其他形状。孔道404可以具有任意合适的横截面,例如,正方形、六边形、圆形,及其组合。对于尾气微粒过滤应用,蜂窝体400可以由陶瓷材料如堇青石、钛酸铝或碳化硅制成。可以使用任何合适的方法来制造蜂窝体400。在堵塞之后,蜂窝体400具有一些的通道406填充了湿胶合剂糊料,从端面402测得填充深度D,所述蜂窝体400进行干燥、固化或烧制以形成堵塞物408和堵塞的蜂窝体。例如,D可以是大于3mm至15mm。
图5和6是根据本公开示例性实施方式,对蜂窝体中的孔道进行堵塞的系统和方法的示意性侧视图。为了对选定的通道进行堵塞,可以通过数种堵塞工艺方法中的一种,迫使水性组合物(例如,所揭示的湿胶合剂糊料)以所选的堵塞图案进入所需的多孔陶瓷蜂窝体的选定开放孔道中以及进入至所需深度。例如,可以通过例如,美国专利第6,673,300号所揭示和所描述的掩膜设备和方法完成堵塞,壁流构造如PCT公开第PCT/US2008/013009号和美国专利申请公开第2009/0286041号所揭示和所描述,其全文通过引用结合入本文。
制造堵塞的蜂窝体的方法包括:使得蜂窝体500的第一端面502与第一掩膜504(例如,具有通过其的开口的挠性掩膜)接触。第一掩膜504可以由如下材料制造,例如:硅酮聚合物或者其他非反应性聚合物,并且可以形成为膜。方法还包括:当第一掩膜504与第一端面502接触的同时,将堵塞介质506(例如,湿胶合剂糊料)经由第一掩膜504注入蜂窝体500的第一端面502中。
将堵塞介质506注入第一端面502中的至少一些孔道508中,从而在对注入的堵塞介质506进行进一步固化或干燥或烧制之后,在这些孔道中最终形成堵塞物510。可以用活塞510将堵塞介质506的块状物(slug)512压入第一端面502中的至少一些孔道508中,从而在这些孔道中最终形成堵塞物510。形成在至少一些孔道508中的堵塞物510优选是与第一端面502齐平或者基本齐平的。方法还包括从第一端面502去除第一掩膜504,即终止第一掩膜504与第一端面502之间的接触。
然后,立即用加热器元件520对第一端面502进行非接触式加热。加热器元件520可以是任意合适的加热器,例如,电加热器、红外加热器、激光加热器、微波加热器、和其他辐射加热器、热空气、热空气鼓风机、和其他的传导和对流加热器等,及其组合。加热器元件520布置在靠近第一端面502以面朝第一端面502。加热器元件520与第一端面502间隔开的距离为522,使得加热器元件520(热源)没有与第一端面502接触。在将堵塞介质506注入到第一端面502中的至少一些孔道508中之后,立即施加热524,以及所述加热524可以是辐射的、传导的(例如通过大气)和/或可以是对流的(例如,通过移动大气,如将热空气吹到第一端面502上)。例如,在将堵塞介质506注入到第一端面502中的至少一些孔道508中之后或者在终止了第一掩膜504与第一端面502的接触之后,立即用加热器元件520对第一端面502进行非接触式加热。
图6显示布置在靠近第一端面502的热源520,其中,热源520与第一端面502间隔开;以及用热源520加热第一端面502,使得第一端面502处的所述至少一些孔道通道508中的湿堵塞胶合剂506仅部分干燥。热源(例如,加热器元件520)可以面朝第一端面502。热源(例如,加热器元件520)可以与第一端面502隔开0.1cm至12.7cm。
在一些实施方式中,作为加热器元件520的非接触式加热的结果,第一端面502中的堵塞介质506仅部分干燥。在一些实施方式中,作为加热器元件520的非接触式加热的结果,更为靠近加热器元件520的堵塞介质506(例如,图4中的470)得到干燥,但是较为远离加热器元件520的堵塞介质(例如,图4中的480)保持湿的。例如,加热器元件520使得第一端面502处的所述至少一部分的孔道通道508中的堵塞胶合剂506在进入所述至少一部分的孔道508中的至少0.1mm深度470的堵塞胶合剂506得到干燥。例如,加热器元件520使得第一端面502处的所述至少一些孔道通道508中的堵塞胶合剂506在进入所述至少一些孔道508中的至少.5mm深度470的堵塞胶合剂506得到干燥。例如,进入所述至少一些孔道通道608中的至少1mm、2mm、5mm、或甚至10mm的深度470。加热器元件520使得第一端面502处的所述至少一些孔道通道508中的堵塞胶合剂506在进入所述至少一些孔道508中不超过90%的深度470的堵塞胶合剂506得到干燥。例如,进入所述至少一些孔道通道608中不超过堵塞深度的80%、60%、50%、30%、或甚至10%的深度470。
方法还包括终止用加热器元件520对第一端面502的加热。在一个实施方式中,在终止用加热器元件520进行非接触式加热之后,堵塞介质506与第一端面502是齐平的。在一个实施方式中,用加热器元件520对第一端面502进行非接触式加热,持续时间段是1秒至15分钟。在另一个实施方式中,用加热器元件520对第一端面502进行非接触式加热,持续时间段是10秒至5分钟。在另一个实施方式中,用加热器元件520对第一端面502进行非接触式加热,持续时间段是10秒至60秒。在另一个实施方式中,用加热器元件520对第一端面502进行非接触式加热,持续时间段是15秒至180秒,例如3分钟或者甚至2分钟。在另一个实施方式中,用加热器元件520对第一端面502进行非接触式加热,持续时间段是10秒至30秒。在一个实施方式中,用加热器元件520对第一端面502进行非接触式加热,所处的温度大于37℃但是小于300℃。在一个实施方式中,通过加热器元件520的非接触式加热,第一端面502维持在大于65℃但是小于288℃的温度。在一个实施方式中,第一端面502维持在大于67℃但是小于300℃的温度。在另一个实施方式中,第一端面502维持在大于75℃但是小于300℃的温度。在另一个实施方式中,第一端面502维持在大于93℃但是小于300℃的温度。在一个实施方式中,在第一位置进行通过第一挠性掩膜504注入堵塞介质506,以及在不同于第一位置的第二位置用加热器元件520对第一端面502进行非接触式加热。
方法还包括用第二掩膜(例如,具有贯穿其的开口的挠性掩膜)与蜂窝500的第二端面528发生接触。对于第二端面528,可以重复上文所述的用于堵塞第一端面502的工艺。可以在第二端面528的没有在第一端面502处注入湿堵塞胶合剂506的至少一些孔道通道404中注入湿堵塞胶合剂506。热源(例如,加热器元件520)可以布置在靠近第二端面528且与第二端面528间隔开,从而用热源520对第二端面528进行非接触式加热,使得第二端面528处的所述至少一部分的孔道通道404中的堵塞胶合剂506仅部分干燥。
可以同时进行或者依次进行堵塞住第一端面502和第二端面528与非接触式干燥第一端面502和第二端面528。在一些实施方式中,然后将蜂窝体暴露于干燥环境,以实现注入到蜂窝体500的端面中的堵塞介质506的完全干燥。
可以使用各种堵塞图案来实现所需的性能。一种常用的堵塞图案是棋盘图案。作为例子,图4显示这样一种棋盘图案,其中每个未堵塞的通道404在所有侧面上被堵塞的通道406所限定,反之亦可。在一些实施方式中,每个通道仅一段被堵塞住,而另一端保持开放。具有在蜂窝体的入口端面被堵住的端部的通道可以被称作出口通道。具有在蜂窝体的出口端面被堵住的端部的通道可以被称作入口通道。通常来说,用于高效微粒过滤的堵塞蜂窝体具有在蜂窝体的两个端面选择性排列的堵塞物,从而进入蜂窝体的流体受迫通过多孔孔道壁,之后离开蜂窝体,实现了用多孔孔道壁收集从流体分离出来的微粒物质。
根据本公开和上文所述的示例性实施方式,制造堵塞的蜂窝体的系统包括:注入元件510,其构造成将湿堵塞胶合剂506注入到从蜂窝体500的端面502延伸的至少一些孔道通道508中;以及加热器元件520,其构造成面朝蜂窝体500的端面502,和构造成在没有发生接触的情况下加热端面502,从而使得端面502处的所述至少一部分的孔道通道508中的湿堵塞胶合剂506仅部分干燥。
系统还可包括传输机530,其构造成移动蜂窝体500,从而将在端面502处的所述至少一些孔道通道508中具有湿堵塞胶合剂506的端面502暴露于加热器元件520。传输机530可以是龙门架、传送带、托盘等,及其组合。传输机构造成在小于或等于5分钟内,使得来自注入元件510的端面502面朝加热器元件520。例如,小于或等于3分钟、小于或等于2分钟、小于或等于1分钟、小于或等于30秒、小于或等于20秒、小于或等于10秒、小于或等于5秒、或者甚至小于或等于1秒。
本公开示例性实施方式的优点包括没有额外的加工步骤,因为可以将热源(例如,上文所述的加热器元件)布置成在现有堵塞系统中,当堵塞的蜂窝体移动到干燥器时对端面进行加热。热源(例如,加热器元件)是可容易调节的,以避免与表面空穴(例如,微凹陷)相对的问题和堵塞-壁分离,如上文所述。此外,本公开的示例性实施方式的优点包括消除了胶合剂堵塞物中的缺陷(例如,微凹陷)。
会理解的是,出于本公开内容的目的,“X、Y和Z中的至少一种”可解释为仅有X、仅有Y、仅有Z,或者X、Y和Z中的两个或更多个项目的任意组合(例如,XYZ、XYY、YZ、ZZ)。
本说明书通篇涉及示例性实施方式以及本说明书通篇的类似语言可以涉及相同实施方式,但不一定如此。此外,本文所述的涉及示例性实施方式的主题物质的特征、结构、或性质可以任何合适的方式组合在一个或多个示例性实施方式中。
对本领域的技术人员显而易见的是,可以在不偏离本公开的精神或范围的情况下对本公开进行各种修改和变化。因此,考虑所附权利要求书覆盖了本文的修改和变化形式,只要它们落在所附权利要求及其等同方式的范围之内。
