Embodiment 1

[0020] Embodiment 1: This lotion that is used to remove the stain on the surface of silverware adopts the following raw materials and methods for removing spots.

[0021] Preparation of lotion: Select an open container, wash it, put 82g of deionized water in the container, then weigh 10g of glycerol, 1g of aluminum powder, 3g of nano-titanium dioxide, and 0.1g of Tween 20, and dissolve or disperse them in sequence into deionized water and stirred evenly to obtain the lotion.

[0022] Stain removal: Clean the oil, dust, dirt and other dirt on the surface of the silverware; put the silverware into the container, so that the lotion is completely immersed in the silverware, the height is only 5mm, too high will affect the light absorption; The container of the silverware is placed under a 20w ultraviolet lamp with a main band less than 400nm for irradiation, and the light source is 20cm away from the surface of the silverware; keep the silverware still at natural temperature, and ...

Embodiment 2

[0024] Embodiment 2: This lotion that is used to remove the stain on the surface of silverware adopts the following raw materials and methods for removing spots.

[0025] Preparation of lotion: Select an open container, wash it, put 80g of deionized water in the container, then weigh 10g of glycerol, 1g of aluminum powder, 5g of nano-titanium dioxide, and 0.1g of Tween 20, and dissolve or disperse them in sequence into deionized water and stirred evenly to obtain the lotion.

[0026] Stain removal: Clean the oil, dust, soil and other dirt on the surface of the silverware; put the silverware into the container, so that the lotion is completely immersed in the silverware, and the height is only 5mm; place the immersed silverware container in the sun Irradiate under light; at natural temperature, keep the silverware still, and after the accumulated light time is 20 hours, take out the silverware and rinse it with clean water.

[0027] Spot removal effect: Before treatment, there...

Embodiment 3

[0028] Embodiment 3: This lotion that is used to remove the stain on the surface of silverware adopts the following raw materials and methods for removing spots.

[0029] Preparation of lotion: Select an open container, wash it, put 75g of deionized water in the container, then weigh 15g of ethylene glycol, 1.5g of aluminum powder, 5g of nano-titanium dioxide, and 0.15g of penetrant JFC, and dissolve or Disperse in deionized water and stir evenly to obtain the lotion.

[0030] Stain removal: Clean the oil, dust, mud and other dirt on the surface of the silverware; place the silverware flat or vertical and fix it firmly, spray or brush this lotion on the surface of the silverware. Put the silverware coated with the lotion under a 40w ultraviolet lamp with a main band less than 400nm and irradiate it. The light source is 15cm away from the surface of the silverware to ensure that all the surfaces to be treated are irradiated with light; at natural temperature, keep the silverwar...

Abstract

The invention discloses a lotion for removing color spots on the surface of silverware. The lotion is mainly prepared from the following components in parts by weight: 65-89 parts of deionized water, 5-15 parts of glycerol or glycol and 1-5 parts of nano titanium dioxide. Nano titanium dioxide is used as an oxidation reduction catalyst in the lotion, a great number of photoelectrons with strong reducing property are formed in a solution through light energy absorption, and the photoelectrons can be used for reducing silver in color spots such as silver sulfide and the like into elemental silver; meanwhile, nano titanium dioxide is used for producing a great number of photoholes with strong oxidation property, and the photoholes can be reduced by alcohol, so that no secondary pollution is caused in the whole process. Alcohol in the lotion is used as a sacrifice agent to be oxidized, and excess alcohol is used as a wetting agent, so that the catalytic activity of nano titanium dioxide can be effectively promoted. The lotion is free of silver loss while removing the color spots on the surface of the silverware, capable of effectively treating silver plated or fine pattern silverware, convenient to operate, free of active metal or corrosive substances to participate in reaction, and free of potential safety hazards.

Description

technical field [0001] The invention relates to a silverware cleaner, in particular to a lotion and a method for removing stains on the surface of silverware. Background technique [0002] Utensils, jewelry, ornaments and other items made of silver have been loved by people since ancient times. Due to the natural characteristics of silver, after long-term contact with air or human sweat, black spots or yellow spots will appear on the surface of silverware, which will affect the surface luster of silverware. People usually mistake it for fading or fading. The main component of this black or yellow stain is silver sulfide, and there are also small amounts of silver chloride and silver oxide. In most cases, it is desired to remove these stains and restore the silver to its pristine whiteness. [0003] At present, these stains can be removed by physical or chemical methods, as follows: [0004] The physical method is to apply physical and mechanical force on the surface of th...
