Step 1: sealing filter medium edge
With DAP Products, Inc. (Baltimore, Maryland) level and smooth, the continuous pearl of the silicon acrylic acid sealant of the commodity of Zhi Zaoing by name " DAP ALEX PLUS " apply around the neighboring of dish (with on every side in abutting connection with), seal the edge of the dish of filter medium 1 (FM1) thus.Make sealant enter the edge of filter medium by scraper.Allow sealant drying at least 8 hours.The FM1 of sealing by this way is decided to be FM3.
Step 2: adhesive tape layer is incorporated on the abrasive material, punches with laser instrument then
Abrasive sheet 1 (AM1) is laminated on the two-sided tape of similar size, and this adhesive tape derives from 3M company with trade name " 3M 964 13 MIL TRANSFER TAPE ".Remove a side base stock of adhesive tape, a side relative with the outer grinding surface on the AM1 sheet manually is laminated to contact adhesive exposure, that be clamminess of adhesive tape.Carry out the laser instrument punching according to 400 pairs of laminated abrasive materials of figure shown in Figure 4.Punching of the laser instrument of this bedded structure and the dish that cuts into 5 inches of diameters are decided to be AM2.
Step 3: filter medium or abrasive material are attached on the AT1.
To be purchased the acyclic side that is administered to the square AT1 sheet that is about 6 inches (15.2cm) from the contact adhesive of 3M company with trade name " SUPER 77SPRAY ADHESIVE ", and make it following dry about 30 seconds at 25 degrees centigrade.The dry weight of adhesive is about 12 milligrams of/square centimeter (mg/cm 2).The circular surface of filter medium FM1, FM2 or FM3 or abrasive material AM5 or AM6 is laminated on the surface of adhesive coating of AT1.Wipe out from the outstanding unnecessary AT1 material in the edge of structure with scissors, form circular, roughly coextensive multi-ply construction.
Step 4: filter medium is attached on the AM2
Remove the base stock of the adhesive tape of AM2, expose the contact adhesive that is clamminess of adhesive tape.The suitable disk of filter medium FM1 or FM3 is alignd with adhesive, manually it is laminated on the adhesive then, make AM2 layer and filtering medium layer be essentially coextensive.
In some cases, FM1 and FM3 are laminated on the dish of FM2 before this, as institute's record hereinafter.In these cases, with the circular surface of the exposure of FM1 or FM3 (promptly be attached to FM2 on surperficial relative side) be laminated on the AM2.
Under AM2 is attached to situation on the tailor's cushion filter medium FM4/FM5, AM2 is attached on the circular surface of exposure of FM4, thereby forms coextensive basically layer.
Step 5: FM1 or FM3 are attached on the FM2
To be applied on the circular surface of filter medium FM1 or FM3 with the contact adhesive that trade name " SUPER 77SPRAY ADHESIVE " is purchased from 3M company, and be applied on the circular surface of FM2, make it following dry about 30 seconds at 25 degrees centigrade.The dry weight of adhesive is about 12 milligrams of/square centimeter (mg/cm 2).Two circular surfaces with the adhesive coating are in alignment with each other then, and laminated each other.Make structure dry, thereby form coextensive basically two-layer structure.
