Embodiment 1

[0033] Embodiment 1, the preparation (lactic acid formula) of descaling agent for food-grade electric kettle:

[0034] Add 40-150g of food-grade lactic acid, 15-45g of food-grade sodium gluconate, 1-15g of practical fruit essence and appropriate amount of pigment into a 500ml beaker, and mix thoroughly. The mixed material A is obtained.

[0035] Take 50g of the above-mentioned mixed material A, put it into a 500ml beaker, add 450ml of water to fully dissolve it, and then divide it into five parts, each with 100g of solution. Pour into 5 triangular flasks numbered No. 1, No. 2, No. 3, No. 4 and No. 5. Put the weighed stainless steel standard corrosion test piece, copper standard corrosion test piece, carbon steel standard corrosion test piece, aluminum standard corrosion test piece and alloy steel standard corrosion test piece into 5 triangular flasks respectively, and time it. After 6 hours, take out the test piece, dry it, weigh it, and calculate the corrosion rate. The co...

Embodiment 2

[0039] Embodiment two, the preparation of food-grade electric kettle descaling agent (malic acid formula):

[0040] Weigh 40-180g of food-grade malic acid, 15-54g of dextrin, and 1-15g of edible lemon essence, put them into a pulverizer, and pulverize fully to obtain the compound material B.

[0041] Get mixed material B and repeat the steps of embodiment one, each metal corrosion rate is as follows:

Abstract

The invention discloses a food grade electric kettle scale dissolver, comprising the following components according to the proportion by weight: 65-90% of poly-organic acid compound, 10-30% of metal anticorrosive and 1-5% of accessories. The poly-organic acid compound refers as a compound with one or more than one acid radicals; the metal anticorrosive is an organic compound with more than 6 hydroxide radicals; the accessories are food grade accessory ingredients. In the preparation method provided by the invention, the poly-organic acid compound is mixed with the polyhydroxy organic compound and the single function of each component and the coordination effect after being combined can be fully realized so that scales can be dissolved, the metal materials can be protected from corrosion; the raw materials used by the scale dissolver are food grade raw materials, and the main ingredients of waste liquor obtained by descaling are food calcium replenishment agent with no toxicity, no harm and no residue which can be naturally degraded fast. The scale dissolver can be directly applied in industrialized production with large market potential and outstanding social and economic benefits.

Description

Technical field: [0001] The invention relates to a descaling agent, in particular to a food-grade electric kettle descaling agent and a preparation method thereof, belonging to the field of chemical industry. Background technique: [0002] At present, there are thousands of descaling products, which are widely used in industry and civil use, and involve all aspects of production and life. In industry, it is mainly boiler scale, pipeline scale, heat exchange equipment scale, etc.; in civilian use, it is mainly scale in winter heating pipe network, central air-conditioning system, automobile water tank scale, aluminum pot scale, electric kettle scale, electric water dispenser scale . Regardless of industrial or civil use, regardless of the size of the equipment, regardless of the material and type, the scale components generated are basically the same, that is, calcium carbonate, magnesium carbonate scale, or a small amount of silicate scale and sulfate scale. [0003] The r...
