Step 2, by clay: quartz: feldspar=3:2:1 prepares burden, pack the material preparing into ball mill, wear into mud;
Step 3, by the mud input stock tank of wearing into, and carry out deironing for the first time with Permanentmagnet bar, with water pump, mud is extracted in high-order pond again, then mud is emitted, and carry out deironing for the second time through magnetic separator, after vibrations are sieved for the second time, mud slowly carries out deironing for the third time through Permanentmagnet bar in stock tank;
Step 4, puts into stock tank by the mud after three deironing and stirs, and the mud after stirring is squeezed into slip drying press with ram pump, and elimination excessive moisture, makes mud squeeze into mud cake;
Step 5, with just practicing machine pugging, pushes mud section by mud cake, makes moisture even;
Step 6, it is rotten that raw material becomes, and mud section piled up in heaps, and stored for several days makes moisture even;
Step 7, moulding and roasting, carry out vacuum pugging, and do insulator on moulding circuit, then the wet base processing advanced to drying room heating, drying, and glazing, finally enters calcination department and carry out roasting;
Step 8, finally carries out mucilage binding, check, warehouse-in.
Further, in step 5, vacuum pugging is taken out the vacuum in mud section to the greatest extent, and becomes the very fine and close mud section of structure through extruding, for the various semifinished products of moulding.
Further, in step 7, glazing is last layer white or brown oil reservoir on base substrate, and employing has a narrow range of temperature, quick heating, and the high calcination department of qualification rate carries out roasting; It is 1354 degree that maturing temperature reaches.
Further, in step 8, mucilage binding adopts No. 525 cement.
Further, the preparation method of this light aging resisting porcelain insulator can produce high voltage suspended insulator, high tension pin-type insulator, high-voltage strut insulator, porcelain pole arm or low tension insulator.
The preparation method of light aging resisting porcelain insulator provided by the invention, passes through following steps: from mine, purchase block raw material, and strictly screen raw material, then with granite wheel roller, block raw material wheel is ground into powder; By clay: quartz: feldspar=3:2:1 prepares burden, pack the material preparing into ball mill, wear into mud; By the mud input stock tank of wearing into, and carry out deironing for the first time with Permanentmagnet bar, with water pump, mud is extracted in high-order pond again, then mud is emitted, and carry out deironing for the second time through magnetic separator, after vibrations are sieved for the second time, mud slowly carries out deironing for the third time through Permanentmagnet bar in stock tank; Mud after three deironing is put into stock tank and stir, and the mud after stirring is squeezed into slip drying press with ram pump, elimination excessive moisture, makes mud squeeze into mud cake; With first experienced machine pugging, mud cake is pushed to mud section, make moisture even; It is rotten that raw material becomes: mud section is piled up in heaps, stored for several days makes moisture further even; Moulding and roasting: carry out vacuum pugging, and do insulator on moulding circuit, then the wet base processing is advanced to drying room heating, drying, and glazing, finally enter calcination department and carry out roasting; Finally carry out mucilage binding, check, warehouse-in.The present invention is simple to operation, and greatly reduces production cost, and the porcelain insulator that explained hereafter of the present invention goes out is ageing-resistant, corrosion-resistant, and good insulation preformance, and physical strength is high.
