Description
Technical Field
The invention relates to the technical field of ceramic firing, in particular to a bonding process of a handle and a body of a medium-high temperature ceramic device.
Background
Ceramics generally have various shapes of handles in addition to the body itself, and the handles are generally disposed at the mouth or neck of the body to perform decorative or functional functions (such as the handle of a ceramic cup, the spout of a ceramic teapot, etc.). For a finished ceramic product, the bonding between the device body and the handle should have the characteristics of uniform sintering stress, mutual infiltration between the handle and the device body, smooth and flat joint, no crack and the like.
At present, the ceramic body and the handle are directly bonded on the body by adopting pug with the same components, and the body and the handle are directly fed into a kiln for firing. However, the body and the handle before firing are formed into a green body and dried, the water content is low, the mud for bonding is not dried, the original high water content is still maintained, after the mud enters a kiln for firing, particularly when the mud is used for firing medium-high temperature ceramics, the firing temperature of the kiln is basically 1000-1300 ℃ or even above 1300 ℃, the mud for bonding is subjected to rapid evaporation of water during sintering to shrink, so that the bonding position is weak, and collapse or fracture is easy to occur under the action of internal stress during cooling, therefore, cracks and uneven lumps are easy to form at the connecting position, so that the bonding between the handle and the body is not firm, and the handle is easy to fracture and fall off from the body.
Disclosure of Invention
The invention aims to provide a bonding process of a handle and a device body of medium-high temperature ceramic, which can improve the bonding strength between the handle and the device body of the medium-high temperature ceramic, so that the joint between the handle and the device body is smoother and smoother without cracks. The technical scheme is as follows:
a bonding process of a handle and a device body of medium-high temperature ceramic comprises the following steps:
step S1: respectively smearing joint mud on the corresponding positions of the dried device handle blank and the device body blank, and bonding the device handle blank to the device body blank to form a complete ceramic blank;
step S2: the ceramic body formed in the step S1 is sent into a kiln to be fired, so that the handle and the body are completely bonded;
the method is characterized in that: the joint mud in the step S1 is prepared by the following steps:
step (1): grinding the asbestos fibers for 16-18 hours until the mesh number of the asbestos fibers is 300-350 meshes;
step (2): and (2) uniformly mixing and grinding 5-10% of the asbestos fiber ground in the step (1), 0.1-0.5% of a thickening agent and 89.5-94.9% of a pug by weight to form the joint mud, wherein the water content of the pug is 35-45%.
The pug used in the joint mud is the same as that used in the ceramic body, so that the technological properties of the joint mud are basically consistent with those of the ceramic body.
In the step S1, the handle blank is bonded to the handle blank by dry bonding, wherein the shape of the interface between the handle and the handle is mild, the bonding is rapid, the position is accurate, and the force is appropriate.
The firing of the high-temperature ceramics in the step S2 is performed in a firing environment of 1000 to 1350 ℃ by using a general conventional technique, referring to the conventional firing method of the high-temperature ceramics. The firing time is different according to different pugs, and the general firing time is 2-6 hours.
The asbestos fiber has good flexibility and strength because the asbestos fiber is composed of fiber bundles which are slender fibers capable of being separated from each other. And grinding the asbestos fibers for a long time of 16-18 hours until the mesh number of the asbestos fibers is 300-350 meshes, so that the asbestos fibers and the pug can be fully mixed. Under the firing environment of medium-high temperature ceramics (the firing temperature is usually 1000-1350 ℃), the ceramic blank is in a semi-molten state, the asbestos fiber is in a molten state, the asbestos fiber respectively permeates into the handle and the device body from the joint, after the ceramics are taken out of a kiln and cooled, the asbestos fiber is respectively arranged at the joint between the handle and the device body and the adjacent handle and device body, on one hand, the drying shrinkage rate of joint mud can be reduced, the drying cracking of the joint mud is avoided, on the other hand, bridging with a structure similar to reinforced cement can be formed, so that the handle and the device body can be bonded more firmly, the bending resistance and the tensile strength of the joint between the handle and the device body are improved, and the crack at the joint between the handle and the device body is avoided.
In addition, the thickening agent is added into the joint mud, and after the asbestos fibers are uniformly mixed with the mud material, the thickening agent can improve the viscosity of the asbestos fibers in the mud material, so that the asbestos fibers and the mud material are combined and integrated tightly, the adhesion of the joint mud is improved, and the adhesion between the handle and the device body is more stable.
As a preferred embodiment of the present invention, the thickener is cellulose ether. Cellulose ethers are one of the water-soluble polymers commonly used in industry, and are thickened mainly by hydration swelling. The cellulose ether is used as a thickening agent, so that the cellulose ether can absorb moisture in the pug during the mixing process with the pug, and the permeability of asbestos fiber is improved, thereby ensuring the viscosity of the joint mud.
As a further preferred embodiment of the present invention, the cellulose ether is at least one of carboxymethyl cellulose and inorganic salts thereof. Carboxymethyl cellulose (CMC) has good hygroscopicity, and generally, when the water content exceeds 20%, the tendency of mutual adhesion between particles of carboxymethyl cellulose increases, the viscosity becomes more pronounced, and the thickening performance becomes higher.
As another further preferred embodiment of the present invention, the cellulose ether is at least one of methyl cellulose and mixed ethers thereof. Methyl Cellulose (MC) has good moisture absorption performance, and can show a characteristic thermal gelation property under the condition of temperature rise, and the viscosity of the joint mud can be further enhanced in the process of kiln temperature rise. The mixed ethers of the foregoing methylcellulose include, but are not limited to, Ethyl Methylcellulose (EMC), hydroxyethyl methylcellulose (HEMC), hydroxypropyl methylcellulose (HPMC), hydroxybutyl methylcellulose (HBMC), carboxymethyl methylcellulose (CMMC), and the like.
As a preferable embodiment of the present invention, the maximum firing temperature in the step S2 is greater than 1300 ℃. When the firing temperature is higher than 1300 ℃, the porcelain clay in the handle blank, the body blank and the joint mud are in a semi-molten state, asbestos fibers in the joint mud permeate into the handle blank and the body blank to form bridging similar to a reinforced cement structure, and the bonding between the handle and the body is firmer after the ceramic is fired and cooled.
Compared with the prior art, the invention has the following advantages:
according to the bonding process of the handle and the device body of the high-temperature ceramic, the asbestos fiber and the thickening agent are added into the joint mud, the ceramic blank is in a semi-molten state in the firing environment of the medium-high temperature ceramic, the asbestos fiber is in a molten state, the asbestos fiber respectively permeates into the handle and the device body from the joint, after the ceramic is taken out of a kiln and cooled, the asbestos fiber is respectively arranged at the joint between the handle and the device body and on the adjacent handle and device body, bridging with a structure similar to reinforced cement is formed, so that the handle and the device body can be bonded more firmly, the bending resistance and the tensile strength of the joint between the handle and the device body are improved, cracks are prevented from appearing at the joint between the handle and the device body, and the joint is smoother and flatter; after the asbestos fiber is uniformly mixed with the pug, the thickening agent can improve the viscosity of the asbestos fiber in the pug, so that the asbestos fiber and the pug are tightly combined and integrated, and the bonding between the handle and the device body is more stable.
Detailed Description
Example one
A bonding process of a handle and a device body of medium-high temperature ceramic comprises the following steps:
step S1: grinding the asbestos fibers for 16 hours until the mesh number of the asbestos fibers is 300 meshes;
step S2: and (3) uniformly mixing and grinding 8% of the asbestos fiber ground in the step S1, 0.5% of a thickening agent and 91.5% of pug in parts by weight to form joint mud, wherein the water content of the pug is 40%.
Step S3: respectively smearing joint mud on the corresponding positions of the dried device handle blank and the device body blank, and bonding the device handle blank to the device body blank to form a complete ceramic blank;
step S4: and (4) feeding the ceramic body formed in the step S3 into a kiln for firing, wherein the maximum firing temperature is 1320 ℃, and the handle and the body are completely bonded.
In step S2, at least one of carboxymethyl cellulose and inorganic salts thereof, or at least one of methyl cellulose and mixed ethers thereof is used as the thickener.
Firing the high-temperature ceramic in the step S4 is performed in a firing environment of 1000-1350 ℃ by adopting a general conventional technology with reference to the conventional firing method of the high-temperature ceramic; the firing time is different according to different pugs, and the general firing time is 2-6 hours.
Example two
Otherwise, the same as in the first embodiment, except that in step S1, the asbestos fibers were ground for 18 hours until the asbestos fibers had a mesh size of 320 mesh.
EXAMPLE III
Otherwise, the same as in the first embodiment, except that in step S1, the asbestos fibers were ground for 18 hours until the asbestos fibers had a mesh size of 350 mesh.
As can be seen from the comparison in the above table, in examples one to three, the joint mud composition, the weight parts of the composition, the moisture content of the mud material, and the maximum firing temperature were the same, except for the grinding time and the grinding mesh number of the asbestos fibers. Since the grinding time of the asbestos fiber of the second and third embodiments is longer than that of the first embodiment, the grinding mesh number of the asbestos fiber is larger, the mixing of the asbestos fiber and the pug is more uniform, and after the ceramic is fired out of the kiln, the asbestos fiber is also distributed more uniformly on the connection part between the handle and the body and the adjacent handle and body, so as to form a bridge with a structure similar to reinforced cement, so that the bonding between the handle and the body can be firmer, and the bending resistance and the tensile strength of the connection part between the handle and the body are improved. The difference between the second embodiment and the third embodiment is only that the grinding mesh number of the asbestos fiber is different, in the actual production process, the grinding technology and equipment requirements are higher as the grinding mesh number of the asbestos fiber is larger, and in order to reduce the technical requirements and the equipment cost, the grinding mesh number of the asbestos fiber is only 320 meshes.
Example four
Otherwise, the same as in example two, except that the maximum firing temperature in step S4 was 1250 ℃.
As can be seen from the comparison in the above table, the difference between the second and fourth examples is only the highest firing temperature, the highest firing temperature of the second example being above 1300 ℃ and the highest firing temperature of the fourth example being below 1300 ℃. In the actual firing process of the second embodiment, when the firing temperature is higher than 1300 ℃, the petuntse, the body blank and the porcelain clay in the joint mud are all in a semi-molten state, the asbestos fiber in the joint mud permeates into the petuntse and the body blank to form a bridge with a structure similar to reinforced cement, and the bonding between the petuntse and the body after the ceramic is fired and cooled is firmer than the firing effect of the fourth embodiment.
EXAMPLE five
Otherwise, the same as in the example, except that the water content of the pug was 45% in step S2.
EXAMPLE six
Otherwise, the same as in the example, except that the moisture content of the pug was 35% in step S2.
As can be seen from the comparison in the table above, the differences between the second, fifth and sixth examples are only in the water content of the pug. Because the joint mud is also added with the thickening agent, the thickening agent uses at least one of carboxymethyl cellulose and inorganic salt thereof with good moisture absorption performance, or at least one of methyl cellulose and mixed ether thereof with good moisture absorption performance, when the asbestos fiber is uniformly mixed with the mud material, the thickening agent can improve the viscosity of the asbestos fiber in the mud material, so that the asbestos fiber and the mud material are tightly combined and integrated, and the adhesion between the handle and the device body is more stable. Therefore, the higher the water content of the pug, the more obvious the viscosity of the asbestos fiber and the pug after mixing and the higher the thickening performance. In the actual firing process, as the pug used in the joint mud is the same as that used in the ceramic body, the pug with the water content of 40 percent can meet the thickening effect.
EXAMPLE seven
In the case that the other portions are the same as those of the example, the difference is that in step S2, 5% by weight of the milled asbestos fiber, 0.5% by weight of the thickener, and 94.5% by weight of the pug are uniformly mixed and milled to form the joint mud.
Example eight
In the case that the rest of the components are the same as those in example seven, the difference is that in step S2, 5% by weight of the milled asbestos fibers, 0.3% by weight of the thickener and 94.7% by weight of the pug are uniformly mixed and milled to form joint mud.
Example nine
In the case that the rest of the components are the same as those in example seven, the difference is that in step S2, 5% by weight of the milled asbestos fibers, 0.1% by weight of the thickener and 94.9% by weight of the pug are uniformly mixed and milled to form joint mud.
Example ten
In the case where the other portions are the same as those in the example, the difference is that in step S2, 10% by weight of the milled asbestos fibers, 0.5% by weight of the thickener, and 89.5% by weight of the sludge are uniformly mixed and milled to form joint mud.
EXAMPLE eleven
Otherwise, the same as in example ten, except that in step S2, 10% by weight of the milled asbestos fiber, 0.3% by weight of the thickener, and 89.7% by weight of the slurry were uniformly mixed and milled to form joint slurry.
Example twelve
Otherwise, the same as in example ten, except that in step S2, 10% by weight of the milled asbestos fibers, 0.1% by weight of the thickener, and 89.9% by weight of the sludge were uniformly mixed and milled to form joint mud.
As can be seen from the comparison of the above tables, examples seven to twelve differ from example two in the parts by weight of asbestos fibers, thickener and sludge. The joint mud of the seventh to ninth examples has asbestos fiber in a smaller weight part than that of the second example, and the finally fired finished ceramic shank and body have a slightly smaller joint strength than that of the second example, and have a smaller bending resistance and tensile strength than those of the finished ceramic of the second example. In the joint mud of the tenth to twelfth examples, the weight parts of the asbestos fibers are larger than that of the second example, and the thickening agent contained in each weight part of the asbestos fibers is smaller than that of the second example, so that the thickening effect of the thickening agent in the joint mud is slightly lower than that of the second example.
In combination with the comparison of the above examples, example two can be selected as the preferred embodiment of the present invention. Other examples the smoothness and flatness of the joint between the shank and body are slightly inferior to those of the second example, although the bond strength and flexural and tensile strengths of the final fired finished ceramic shank and body are within acceptable limits.
The above-mentioned method for testing the bonding strength, bending resistance and tensile strength between the handle and the body of the finished ceramic product according to each example can refer to the research on firmness test of handles of daily ceramic cups published in "china ceramics" 2019, 11 th, and the testing device described therein can be used to perform similar corresponding tests on the connection between the handle and the body of the ceramic product by applying static loading and vertical impact to the body under the condition of fixing the handle.
In addition, it should be noted that the names of the parts and the like of the embodiments described in the present specification may be different, and the equivalent or simple change of the structure, the characteristics and the principle described in the present patent idea is included in the protection scope of the present patent. Various modifications, additions and substitutions for the specific embodiments described may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
