Method of forming partitions of plasma display panel and device for forming partitions

Abstract

In a method of forming partitions of a plasma display panel, the partitions of the plasma display panel are formed by using a sandblasting method, and abrasive material and partition cutting powder are dispersed in liquid after the completion of sandblasting. Further, in a device for forming partitions of a plasma display panel, the partitions of the plasma display panel are formed by a sandblasting method, and the device has a dispersing tank in which abrasive material and partition cutting powder are dispersed in liquid after the completion of sandblasting.

1 . A method of forming partitions of a plasma display panel in which the partitions of said plasma display panel are formed by using a sandblasting method, wherein abrasive material and partition cutting powder are dispersed in liquid after the completion of sandblasting. 
   
   
       2 . The method of forming partitions of a plasma display panel as claimed in  claim 1 , wherein the liquid is organic solvent, water or water and dispersing agent. 
   
   
       3 . The method of forming partitions of a plasma display panel as claimed in  claim 1 , wherein abrasive material and partition cutting powder are dispersed in liquid after the completion of sandblasting and classified by wet classification. 
   
   
       4 . The method of forming partitions of a plasma display panel as claimed in  claim 3 , wherein rough powder, which has been classified by the wet classification, is dried in a continuous drying furnace and reused as abrasive material. 
   
   
       5 . The method of forming partitions of a plasma display panel as claimed in  claim 4 , wherein a percentage of water contents of the dried abrasive material is not more than 5%. 
   
   
       6 . The method of forming partitions of a plasma display panel as claimed in  claim 4 , wherein processing in which the abrasive material and the partition cutting powder after a process of sandblasting are dispersed in liquid, processing in which the abrasive material and the partition cutting powder after a process of sandblasting are subjected to wet classification and processing in which rough powder, which has been classified by wet classification, is dried in a continuous drying furnace so that the abrasive material can be reused are continuously performed. 
   
   
       7 . The method of forming partitions of a plasma display panel as claimed in  claim 3 , wherein the fine powder, which has been classified by the wet classification, is dehydrated and solid contents are discarded and the liquid is reused. 
   
   
       8 . A device for forming partitions of a plasma display panel in which the partitions of said plasma display panel are formed by a sandblasting method, comprising:
 a dispersing tank in which abrasive material and partition cutting powder are dispersed in liquid after the completion of sandblasting.   
   
   
       9 . The device for forming partitions of a plasma display panel as claimed in  claim 8 , wherein the liquid is organic solvent, water or water and dispersing agent. 
   
   
       10 . The device for forming partitions of a plasma display panel as claimed in  claim 8 , further comprising:
 a hydro-cyclone for classifying the abrasive material and the partition cutting powder after the completion of sandblasting, which are dispersed in liquid, by wet classification.   
   
   
       11 . The device for forming partitions of a plasma display panel as claimed in  claim 10 , further comprising:
 a continuous drying furnace for drying rough powder, which has been classified by the wet classification, so as to reuse the abrasive material.   
   
   
       12 . The device for forming partitions of a plasma display panel as claimed in  claim 11 , wherein the continuous drying furnace dries the abrasive material to be reused so that a percentage of water contents of the dried abrasive material can not more than 5%. 
   
   
       13 . The device for forming partitions of a plasma display panel as claimed in  claim 11 , wherein said dispersing tank for dispersing the abrasive material and partition cutting powder in liquid after the completion of sandblasting, said hydro-cyclone for classifying the abrasive material and partition cutting powder, which are dispersed in liquid after the completion of sandblasting, by the wet classification and a continuous drying furnace for drying the rough powder, which has been classified by the wet classification so as to reuse the abrasive material, are arranged so that processing can be continuously performed. 
   
   
       14 . The device for forming partitions of a plasma display panel as claimed in  claim 10 , further comprising:
 a dehydrator for dehydrating the fine powder, which has been classified by the wet classification, so as to discard the solid components and reuse the liquid.
