Honeycomb filter for exhaust gas decontamination, adhesive, coating material and process for producing honeycomb filter for exhaust gas decontamination
Abstract:
A honeycomb filter for purifying exhaust gases includes columnar porous ceramic members and an adhesive layer combing the ceramic members with one another. Each porous ceramic member has a partition wall and through holes. The through holes are extending in parallel in length direction of the ceramic members. The partition wall is separating the through holes and filters particulates in exhaust gas. The through holes include ones sealed at inlet side of the ceramic members and ones sealed at outlet side of the ceramic members such that the exhaust gas enters from the inlet side, passes through the partition wall and flows out from the outlet side. The adhesive layer has thermal expansion coefficient αL. The ceramic members have thermal expansion coefficient αF. The thermal expansion coefficient αL of the adhesive layer and the thermal expansion coefficient αF of the ceramic members satisfy relationship, 0.01
Abstract(Chinese):

用于净化废气的蜂窝过滤器包括柱状多孔陶瓷构件和将陶瓷构件彼此结合的粘合剂层。 每个多孔陶瓷构件具有分隔壁和通孔。 通孔在陶瓷构件的长度方向上平行延伸。 分隔壁分离通孔并过滤废气中的颗粒物。 通孔包括在陶瓷构件的入口侧密封的通孔和在陶瓷构件的出口侧密封的通孔，使得废气从入口侧进入，通过分隔壁并从出口侧流出。 粘合剂层具有热膨胀系数αL。 陶瓷构件具有热膨胀系数αF。 粘合剂层的热膨胀系数αL和陶瓷构件的热膨胀系数αF满足关系式0.01≤αL-αF| /αF<1.0。
