In sum, the metallized technology of present known nonmetal medium material surface, though cut both ways, but all do not break away from traditional electroplating technology category, thus the processing method complexity, the processing requirement height, cycle process period is long, and be subject to the restriction of workpiece size and shape thereof, lack maneuvering ability, and different metallic substance is carried out with a kind of processing.Particularly contain hypertoxic elements such as prussiate and sexavalent chrome in electroplate liquid again, waste water control is difficulty very, and the control expense height more, and environmental pollution is serious.
Summary of the invention:
The purpose of this invention is to provide a kind of Metalation technology of microwave medium multicavity filter, with not containing virose molecule silver slurry silver is soaked on the microwave-medium surface, centrifugation, oven dry and pre-burning are repeatedly, carry out high temperature sintering at last, overcome the shortcoming that contains harmful element in the metal electroplating solution, solved problem of environmental pollution.
A kind of Metalation technology of microwave medium multicavity filter, it is characterized in that multi-cavity microwave-medium ceramics matrix is placed screen cloth, by soaking silver in the silver slurry of buncher driving screen cloth in silver slurry bucket, and by low speed to high speed rotating, by placing the lifting motor drive silver slurry bucket in the fixed support to separate with screen cloth, buncher drives the screen cloth high speed rotating more then; Ceramic matrix after drying is put into baking oven dry, be placed on and make silver slurry silver ink firing, curing in the tunnel furnace, through repeatedly soaking silver, oven dry, silver ink firing, curing, at high temperature sintering is finished its metallization process process at last.
Now be described below soaking silver-colored machine structure and operation process:
Soaking silver-colored machine is made up of buncher, screen cloth, silver slurry bucket, silver-colored slurry, lifting motor and fixed support.The microwave-medium ceramics matrix places screen cloth, screen cloth is driven by buncher, the microwave-medium ceramics matrix in being built in silver slurry bucket, screen cloth is rotated in the silver slurry, lifting motor can drive silver slurry bucket and do upper and lower lifting, so that the microwave-medium ceramics matrix in the screen cloth is immersed in the silver slurry of silver slurry bucket, and then make it be separated from silver slurry barrel interior silver slurry, under buncher drives, the silver slurry of microwave-medium ceramics matrix on screen cloth drive backspin is transferred it dried again.
The baking oven of microwave-medium ceramics matrix after the drying of silver slurry being put into 200 ℃～500 ℃ of temperature is dried, and then the ceramic matrix after will drying silver ink firing, curing in 600 ℃～800 ℃ tunnel furnace, then, repeatedly repeat above-mentioned silver, oven dry, silver ink firing, the solidification technical process of soaking again, at last in tunnel furnace, finish sintering with 700 ℃～900 ℃ top temperature, its objective is and improve the sticking power of silver layer on the microwave-medium ceramics matrix, finish the Metalation technology of microwave medium multicavity filter process.
The advantage of Metalation technology of microwave medium multicavity filter of the present invention is as follows:
1, need not to adopt the method that contains poisonous element electroplate liquid to make the ceramic matrix surface metalation, help environmental protection, eliminated pollution.
2, the present invention makes ceramic matrix surface metalation technological process methods simplification, is convenient to industrial production, the efficient height, and the silver layer strong adhesion, and silver thickness is even.
