Problems solved by technology

[0018] However, the antibacterial glass that shows acidity when dissolved as described in Patent Document 2 is based on the premise that it is used in combination with the antibacterial glass that shows alkalinity when dissolved, so it can be found that when used alone, the dissolution rate is too fast, and it is difficult to maintain the specified temperature for a long time. The problem of the dissolved amount of silver ions
[0019] In addition, it was also found that with the excessive increase of the dissolution rate, the amount of silver ion elution increased excessively, so the use of excess silver ions tended to cause coloring of the laundry.

Embodiment 1

[0229] 1. Fabrication of antibacterial glass

[0230] (1) Melting process

[0231] As an antibacterial glass composition, the glass raw material of the composition shown in Table 1 was stirred with the universal mixer at the rotation speed of 250 rpm, and 30 minutes until it mixed uniformly.

[0232] Subsequently, using a glass melting furnace, the glass raw materials were heated at 1280° C. for 3.5 hours to produce molten glass.

[0233] (2) Molding process

[0234] Such as Figure 14 As shown in (a) to 14(b), the molten glass 42 taken out from the glass melting furnace is introduced into the forming device 40, and formed as follows: Figure 11 Tablet-shaped antibacterial glass 22 shown (maximum diameter: 10 mm, surface area each: 2.5 cm 2 ).

[0235] (3) Surface grinding process

[0236] 500 g of the obtained tablet-shaped antibacterial glass is dropped into a vibrating ball mill that does not use a medium. Subsequently, 500 g of isopropanol was added, and in this sta...

Embodiment 2

[0278] In embodiment 2, antibacterial glass composition, as shown in table 1, Ag 2 While the content of O and CoO is kept as it is, the content of ZnO is reduced to 4.05% by weight, and for other components, the proportion is maintained, and the corresponding increase is due to the reduction of the content of ZnO. In addition, in the same manner as in Example 1, a Antibacterial glass and evaluation. Table 1 shows the obtained results.

Embodiment 3

[0280] In embodiment 3, antibacterial glass composition, as shown in table 1, Ag 2 While the content of O and CoO is kept as it is, the content of ZnO is reduced to 0% by weight, and for other components, the proportion is maintained, and the corresponding increase is due to the reduction of the content of ZnO. In addition, in the same manner as in Example 1, a Antibacterial glass and evaluation. Table 1 shows the obtained results.

Abstract

Provided is an antibacterial glass which can be accommodated in a narrow accommodating space in an antibacterial water unit for supplying antibacterial water to a washing tube of a washing machine, is capable of effectively suppressing the occurrence of black mold and the like in the washing tub, and can effectively inhibit bacteria on laundry while suppressing discoloration thereof. An antibacterial glass for releasing silver ions and exhibiting antibacterial effects in direct contact with water, the Ag2O content thereof being within the range of more than 5 wt% to 10 wt% or less, the P2O5 and CaO content being within a predetermined range, the ZnO content being less than 10 wt%, and the K2O, Al2O3, and MgO content being within a predetermined range with respect to a total quantity of 100 wt%, and the shape of the antibacterial glass being a doublet shape having a maximum diameter in a predetermined range.

Description

technical field [0001] The present invention relates to an antibacterial glass, in particular to a kind of antibacterial glass that can be accommodated in the narrow storage space of an antibacterial water unit for supplying antibacterial water to the washing tank of a washing machine, and can effectively suppress the bud-like glass in the washing tank. It is an antibacterial glass that prevents the generation of cladospores, etc., and can suppress coloring of the laundry while making it antibacterial. Background technique [0002] In the prior art, in order to prevent bacteria and mold from multiplying in the water contained in the water storage tank and the drain pan of the air conditioner, etc., it is widely used to directly contact with water and release silver ions in the water to exert an antibacterial effect. Antibacterial glass. [0003] In addition, the antibacterial glass used in related applications needs to maintain a predetermined amount of silver ion elution o...
