Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with examples are described in detail below.
Example 1
A storage method of a honeycomb ceramic filter (DPF) pug comprises the steps of wrapping a single pug by using glutinous rice paper according to the water content of the pug (cylindrical), and then putting the pug into a closed container for storage, wherein the glutinous rice paper mainly comprises starch, and the starch is basically the same as a pore-forming material in the DPF pug. In order to determine the beneficial effect of using the glutinous rice paper to store the pug, a test group and a control group are provided and respectively tested, and the test is as follows:
the test group randomly selects 5 blocks of pugs as test pugs, the numbers of the pugs are 1#, 2#, 3#, 4# and 5#, the initial water content of the 5 blocks of pugs is 22.46%, 22.52%, 22.48%, 22.49% and 22.51%, and the average weight of the pugs is 10 kg; according to the initial water content, each pug is wrapped by 2 layers of glutinous rice paper with the thickness of 0.025mm, the total weight of the two layers of glutinous rice paper is less than 10g, and the weight of the glutinous rice paper is only 1 per thousand of the weight of the pug and can be ignored; then, placing the pug into a plastic box with good tightness, stacking the pug according to a structural schematic diagram shown in fig. 1, wherein the stacking process preferably does not exceed 5 layers, the stacking layer is too high, and the weight of the pug is too large, so that the lower pug generates obvious deformation, and further glutinous rice paper is easy to deform, and the storage effect is influenced; and then, tightly covering the cover of the plastic box, storing for 48 hours at the constant temperature of 20 ℃, and detecting the water content of the 5 pugs after the storage is finished, wherein the water content of the 5 pugs is respectively 22.46%, 22.51%, 22.48% and 22.51%, and the change rates of the water content before and after the storage are respectively 0, 0.04%, 0, 0.04% and 0.02% according to the calculation.
Randomly selecting 5 blocks of pugs as test pugs by a comparison group, wherein the numbers of the pugs are 6#, 7#, 8#, 9# and 10#, the initial water contents of the 5 blocks of pugs are 22.51%, 22.48%, 22.53%, 22.49% and 22.49%, respectively, and the average weight of the pugs is 10 kg; and then directly placing the pug into a plastic box with good sealing performance, wherein the placing mode is the same as that of a test group, then tightly covering a cover of the plastic box, storing for 48 hours at a constant temperature of 20 ℃, and detecting the water content of the pug after the storage is finished, wherein the water content of the five pugs is respectively 22.47%, 22.45%, 22.53%, 22.51% and 22.5%, and the change rates of the water content before and after the storage are respectively 0.18%, 0.13%, -0.09%, -0.04% and 0.04% according to the calculation.
The test results are shown in table 1, and it can be known from table 1 that the water content of 5 pugs in the test group is in a more stable state in the storage process, even no change occurs; for the pug of the control group, the water content has a large change, the phenomenon of obvious reduction or rise occurs, and the water content of the pug is unstable, so that the quality of the pug is reduced, and the subsequent application process of the pug is influenced. In addition, the glutinous rice paper is broken when meeting pressure and is dissolved in the pug, the main component of the glutinous rice paper is starch which is basically the same as the pore-forming material in the DPF pug, the quality of the glutinous rice paper is negligible relative to the wrapped pug, potential adverse effects on the next pugging or forming process cannot be caused, a blocking net or a die cannot be blocked, the work of removing the glutinous rice paper can be avoided, and the work efficiency is improved; and the automatic production is easy to realize.
