Description

Manufacturing method of dirt removal polish

The present invention is to remove and surface dirt on various surfaces, such as surface coating surface, various metal surface plastics, and to give the primary color gloss of materials (raw materials) of various equipments and devices, the surface of the surface to remove the gloss such as mirror (mirror) It relates to a manufacturing method of a brightener.

Today's cleaners come in many varieties. Wash with chemical compounds and wash and apply. To remove their contaminated dirt, water and solvent-type oils are used to remove them, and then wax type is used to give luster.

Or in the manufacture and manufacture of various devices and appliances, the metal plate surface is divided into two categories. To remove a lot of fine oxides and wounds on the product First, to treat the oxide on the metal surface First, select a solution of hydrochloric acid, sulfuric acid, phosphoric acid, etc. diluted by the metal material, immerse it in the solution, wash it with water, and then polish or paint There are many manpower that need to go through the complicated process of polishing, and detailed and detailed long time effort and process problems. Second, there is an example that generally uses wire sole and chopped pepper.

There is also a problem of making minute wounds on various surfaces. So, if you look into the various ways to remove the dirt is divided into three types of dirt. Various surfaces, such as metal surfaces, plastic surfaces, and painted surfaces, rarely maintain their own surfaces. Various kinds of metal surfaces are attached to oxides and dusts such as condensation, formwork, fingerprints, and sweat, so that the quality and quantity of the dirt are well considered and appropriately treated. Therefore, various kinds of dirt are classified as follows.

(1) Organic matters: Organic matters belonging to carbide fats and oils, etc., should be polished with acid and alkaline fats and oils.

(2) Inorganic matters: Oxides and various acid treatments and polishing treatments.

(3) Organic and inorganic mixtures: Dirt mixed with fats and oils and fine particles of oxides is very strongly adhered by the heat of polishing when polishing various surfaces with one kind of oxide. Thus, the above-mentioned dirt is treated like a fine wound. So chemical and polishing methods were found to effectively remove dirt and polish.

(4) The present invention combines and mixes the properties and properties of fatty acids, alkalis, silicone oils, oxides, and the like.

4-1. fatty acid

Stearic acid (solid) oleic acid (liquid) is given in the contents. Oils and fats are animal and vegetable and adjust the flexibility from solid to liquid according to the purpose of use. The amount of silicone oil can also be adjusted.

4-2. Chromium oxide and silicon oxide

Oxides and carbides may be used in a wide range, but about 57 species are commonly used. Among them, chromium oxide and silicon oxide are selected and carried out. By the way, it should be noted that two kinds should be used, and soft and steel can be polished and there should be almost no chemical change in alcohol, acid and alkali diluted with water. As mentioned above, this is the correct method of use.

4-3. Magnesium carbonate

As a polishing aid, the compound is compounded with alkali metal oil in a semi-oil phase. Water-soluble property prevents the dispersion of chromium oxide and silicon oxide when water is added, and helps lubrication between oxides, reduces self-heat during polishing and helps polishing.

4-4. Boric acid

As a polishing aid, the compound is compounded with alkali metal oil in a semi-oil phase. Dissolve in water. It helps lubrication when water is not used in polishing, prevents dispersion in oxide powder, reduces frictional heat between each other and helps polishing effect. It also acts as a pesticide and preservative.

4-5. Methyl silicone oil

Methyl silicone oil is {(CH ₃ ) ₂ Si (OH) ₂ } _n Where n is the viscosity is appropriately adjusted according to the raw material formulation. It prevents deterioration of solidification, controls flexibility, and helps with film development. That is, it is not chemically stable. Therefore, it is called reactive silicone oil. Or as a preservative and helps to lubricate and coat during polishing.

4-6. Acetone

As a low-solvent solvent, use it with its properties and properties. In other words, acetone is diluted with water as a plastic solvent and combined with other compounds to act as a prerequisite on the surface of the plastic and as a soluble mixture such as degreasing or soda fluoride, silicon oil, magnesium carbide, and water on the metal surface.

4-7. Soda Fluoride

Fluorine alone does not exist in air. Coexists with other compounds. Therefore, fluorine is a metal surface treatment agent to help remove oxides, and soda (sodium) is intended for metal surface treatment, base removal and anti-fatty acid. However, various metal surfaces and plastic surfaces should be treated properly within the range not to corrode.

(5) The chemical composition of the present invention will be described with reference to Examples according to the manufacturing process and the processes.

[Step 1]

20% by weight of stearic acid, 6% by weight of oleic acid, 0.5% by weight of sodium fluoride, 2.5% by weight of water, diluted with water, combined with dilute concentration, and heated to 80 ℃, they become bounced in a liquid state.

[Step 2]

25 wt% chromium oxide, 15 wt% silicon oxide, 10 wt% boric acid, 10 wt% magnesium carbide and the like are mixed and mixed in the liquid alkali metal oil in the liquid.

[Step 3]

In a completely combined state in the second step while cooling to room temperature while diluting 5% by weight of methylsilicone oil 5% by weight of acetone and water 1: 2 at 20 ℃ compounded and mixed to 20% by weight and completely cooled to room temperature.

However, as a reference example, a variety of phenomena occur as a result of conducting oxides and carbides such as fatty acids and organic substances. In adverse conditions, when the compound and the mixture contain ethylene trichloride (trichloroethylene trichlorene), it is heavier than water and hardly soluble in water, but water can be used to prevent evaporation from the surface. However, by decomposing in water to produce a small amount of hydrochloric acid, the surface of alloy metals such as zinc or aluminum is not particularly useful in the case of the surface of the base which is easily soluble in acid.

Therefore, in order to compensate for this phenomenon, acetone is used as a soluble catalyst for compound to combine with fluoride and water or a compound. It is a compound and mixture that does not harm the human body, and it is convenient to remove dirt on various surfaces. It is glossy like) and the surface of methylsilicone oil forms a film that delays the gloss effect.
