Problems solved by technology

However, the wear resistance of the higher fatty acid metal salt molded body obtained by either method is low, and a molded body with high durability cannot be obtained.
In addition, in any higher fatty acid metal salt block molded body, the abrasiveness by a brush etc. is not constant, and the molded body can only be ground in a small amount at the beginning of brush grinding, and the grinding powder does not adhere to the roller surface , the wear of the roller is severe, the durability of the copier is poor, and it is far from the ideal supply state
In addition, in order to increase the initial grinding amount, it is also conceivable to soften the molded body of higher fatty acid metal salt block, but the life of the molded body is shortened, which is not practical.

Embodiment 1

[0063] Mold ( Figure 11 ) is to have such as figure 2 The shape of the groove of the S-section block molded body shown in (A) is 5 mm in length x 5 mm in width and 310 mm in length. Insert 10 molds and 3 heaters with 16 fastening bolt holes spaced on the left and right. A plate and a flat plate are combined and fastened so that the groove surface is in contact with the flat surface of other molds, and installed on a mold base equipped with a heater insertion port and a cooling mechanism as a combination of molds that can mold a total of 320 blocks ( Figure 12 , Figure 13 ). In addition, 3 sheath heaters are installed on the top, middle and bottom of the mold, and 2 sheath heaters are installed on the cover plate for heat insulation and the mold base, for a total of 13. Sheath heater. In addition, in the figure, 41 is the upper heater insertion port, 42 is the middle heater insertion port, 43 is the lower heater insertion port, 44 is the temperature drop sensor inserti...

Embodiment 2

[0065] In addition to the change becomes to have as image 3 A higher fatty acid metal salt block shaped body was produced in the same manner as in Example 1 except for the die having grooves of the S-section block shaped body shown in (A). The results are shown in Table 1.

Embodiment 3

[0067] In addition to the change becomes to have as Figure 4 A higher fatty acid metal salt block shaped body was produced in the same manner as in Example 1 except for the die having grooves of the S-section block shaped body shown in (A). The results are shown in Table 1.

Abstract

Metal salts of higher fatty acids are produced by heating metal salts of higher fatty acids to fuse and solidifying. The metal salts have four edges on a section which is perpendicularly cut off with respect to the length direction; at least an edge in four edges has a curve and / or a broken line. The high zinc fatty acids will not generate cracks, have small hardness deviation, have a controllable grinding quantity grinded by a brush and etc. and a good supply state, and are used in office equipment such as an electrostatic printer and etc. and other precision equipment as a lubricant, a cleaning auxiliary and etc.

Description

technical field [0001] The present invention relates to a high-grade fatty acid metal salt block molded body having stable and suitable properties for use as lubricants, abrasives, cleaning aids, developing aids, etc. in office equipment such as electrostatic copiers, and an electrophotographic device. Background technique [0002] Conventionally, higher fatty acid metal salts have been used as lubricants, abrasives, cleaning aids, or developing aids in office equipment such as electrostatic copiers. Higher fatty acid metal salts are finally used in powder form, but as a supply method, for example, as shown in Japanese Patent Application Laid-Open No. 2009-15229 (Patent Document 1), the higher fatty acid metal salts are preliminarily agglomerated, and then the metal salts of higher fatty acids are formed into blocks by a brush or the like. The method of scraping it and supplying it to the necessary part has already been put into practical use. [0003] Figure 15 An example...
