Referring to the accompanying fig. 1 of the specification, a first preferred embodiment of the method 100 for detecting the sealing performance of the aluminum honeycomb product provided by the present invention is illustrated, and the method 100 for detecting the sealing performance of the aluminum honeycomb product can effectively detect the sealing performance of the aluminum honeycomb product, and is an effective supplement to the detection of the sealing performance of the aluminum honeycomb product.
It should be noted that the method 100 for detecting the sealing performance of the aluminum honeycomb product provided by the present invention is used for detecting the sealing performance of the aluminum honeycomb product, including but not limited to a plate or a part of a cemented aluminum honeycomb sandwich structure having a sealing performance requirement. In other embodiments, the method 100 for detecting the sealing performance of the aluminum honeycomb product can also be used to detect the sealing performance of other material honeycomb products having the sealing performance requirement, such as but not limited to a stone honeycomb plate, a stainless steel honeycomb plate, a glass honeycomb plate, and the like.
Specifically, the method 100 for detecting the sealing performance of the aluminum honeycomb product comprises the following steps:
101: weighing a first aluminum honeycomb detection sample for the first time, wherein the first aluminum honeycomb detection sample comprises a dried aluminum honeycomb product and sealing gel sealed at the periphery of the aluminum honeycomb product;
102: completely immersing the first aluminum honeycomb test specimen in water;
103: after a preset time, taking out and wiping the first aluminum honeycomb detection sample, and immediately weighing the first aluminum honeycomb detection sample for the second time; and
104: and determining the sealing performance of the aluminum honeycomb product of the aluminum honeycomb detection sample based on the water absorption capacity of the first aluminum honeycomb detection sample, wherein the water absorption capacity of the first aluminum honeycomb detection sample is the difference of two weight scales.
Further, in the step 101 and the step 102, the first aluminum honeycomb product is weighed by using an electronic balance, and the weight is accurate to gram.
In step 102, the first aluminum honeycomb test sample is completely immersed in water, so that all parts of the first aluminum honeycomb test sample can be contacted with water, and the accuracy of the sealing performance test result is improved.
Preferably, when the first aluminum honeycomb detection sample is completely immersed in water, the distance from the top end of the first aluminum honeycomb detection sample to the water surface is more than 20mm, so that the liquid pressure acting on the first aluminum honeycomb detection sample is ensured, and the accuracy of the sealing performance detection result is improved.
In step 103, after the first aluminum honeycomb test sample is completely immersed in water for the preset time, the water on the surface of the first aluminum honeycomb test sample is taken out and wiped dry, and then the first aluminum honeycomb test sample is weighed for the second time immediately. It can be understood that the difference between the two weighing qualities can be obtained more effectively only when the first aluminum honeycomb detection sample is completely immersed in water for a sufficient time, and the accuracy of the test is improved.
After the first aluminum honeycomb detection sample is taken out from water, the liquid attached to the surface of the first aluminum honeycomb detection sample is wiped, so that the influence of the attached liquid on the weight weighing result is prevented, and the test precision is improved.
After the liquid attached to the surface of the first aluminum honeycomb detection sample is wiped dry, the first aluminum honeycomb detection sample is weighed for the second time, so that the liquid adsorbed by the first aluminum honeycomb detection sample is prevented from volatilizing and immersing in air or the moisture in the air is prevented from immersing in the first aluminum honeycomb detection sample, and the sealing performance detection accuracy is improved.
Preferably, the preset time is longer than two hours, so that the first aluminum honeycomb detection sample can be in contact with liquid for a sufficient time.
In step 104, the water absorption of the first aluminum honeycomb test sample is equal to the weight weighed in the second time minus the weight weighed in the first time. It can be understood that the larger the value of the water absorption capacity of the first aluminum honeycomb test specimen, the worse the sealing performance of the first aluminum honeycomb test specimen; the smaller the value of the water absorption amount of the first aluminum honeycomb test sample is, the better the sealing performance of the first aluminum honeycomb test sample is.
It is understood that the correspondence between the water absorption capacity and the sealing performance can be established by means of a plurality of tests, and after the water absorption capacity of the first aluminum honeycomb test sample is determined, the sealing performance of the aluminum honeycomb article of the first aluminum honeycomb test sample is evaluated based on the correspondence.

105: manufacturing the aluminum honeycomb product with a preset size;
106: drying the aluminum honeycomb article; and
107: and sealing and forming sealing gel at the periphery of the aluminum honeycomb detection product so as to form the first aluminum honeycomb detection sample.
Preferably, in step 105, the predetermined dimensional horizontal cross-sectional dimension of the aluminum honeycomb article of the first aluminum honeycomb test specimen is 500mm by 500 mm. It is understood that the horizontal cross-sectional dimensions of the aluminum honeycomb article being fabricated can also be implemented in other dimensions, such as, but not limited to, 400mm by 400mm, 400mm by 500 mm; the horizontal cross-sectional shape of the aluminum honeycomb article can also be implemented in other shapes, such as, but not limited to, triangular, circular, oval, and the like.
In step 106, before sealing to form a sealing gel, the aluminum honeycomb product is put into a drying oven for moderate drying to ensure that the surface of the aluminum honeycomb product is dry and free of water drops.
In step 107, the periphery of the aluminum honeycomb product is sealed by using a sealant, and then the aluminum honeycomb product is cured until the sealant is solidified to form the sealing gel.
Note that the periphery of the aluminum honeycomb product refers to a side edge that coincides with the thickness direction of the aluminum honeycomb product. In other words, the sealing gel serves to prevent liquid from infiltrating into the aluminum honeycomb article from gaps formed by the respective sheets of the aluminum honeycomb article being stacked on top of each other.
