The agent is intended for use in construction, particularly in house factories, for cleaning the surfaces of concrete building elements or surfaces of metal molds. It can also be successfully used in households and for degreasing various surfaces. Concrete building elements are cast in metal forms; the walls of which on the inside are covered with various types of agents that reduce adhesion concrete mass to the surface of the mold. As a result of this activity, the concrete mass, after setting, sticks more easily from the mold. The surfaces of such an element are very often greasy. During the storage and assembly of 20 such elements, greasy surfaces easily cover the dust from the atmosphere and without degreasing the surfaces of these elements cannot be covered with paint coatings or tapelt. State of the art. Agents for removing Haustyeh and / or dusty contaminants from surfaces (concrete, being an aqueous solution of 2.5% trisodium phosphate, or a 5% to 10% solution of hydrochloric acid) are known. to be rinsed thoroughly and clean water, they are also known to remove contaminants from ~ lx) fused surfaces and / or solder dusty surfactants, being a combination of sodium alkylarylsulfonates and sulphates , high molecular weight alkyl compounds, or the combination of sodium alkylaryl sulfonates with urea or sodium tripolyphosphate with a nonionic surfactant.

Claims

reservations due to corrosion of the plate of the reinforcement bars, as well as the destructive effect of hydrochloric acid on the concrete material. The use of trisodium phosphate, as well as agents containing an active substance, called sodium triphosphate, is unacceptable, due to the protection of the human environment, phosphorus compounds are very difficult to biodegrade and are not to be removed in municipal sewage treatment plants. The presence of these compounds in rivers may cause significant disturbances in the biocenosis of surface waters. Alkylarylsulfonates, which are the basic component of many surfactants, exhibit a similarly difficult degradability, or low biodegradability. The promotion of the difficult decomposition of phosphorus compounds and many surface-active compounds is currently very strictly presented in many countries 97 24 397 243 3 from the point of view of social hygiene and human environmental protection. More and more often, the admission to use and to the commercial circulation of detergents not meeting the required biodegradability is refused. The use of sodium metasilicate in degreasing agents is very advantageous because sodium metasilicate inhibits the corrosion of metals in the degreasing baths. The inhibitory effect of sodium metasilicate consists in the release of silicic acid gel films on the surfaces of the cleaned metals. Sodium metasilicate also shows disinfecting and saponifying properties for vegetable and animal oils. Thanks to these properties, it is used as an ingredient in washing and disinfecting agents used in the dairy and beverage industry. Sodium metasilicate also exhibits dirt and contamination dispersing properties. It is therefore used in detergents containing soap, especially for prewashing work clothes. Sodium metasilicate counteracts the hydrolysis of the soap and causes that even at its low concentration, the washing bath has an optimum pH of 10.8 for the washing action of the soap. In such an environment, the dirt is very easily dispersed by sodium metasilicate and removed by the washing process. The essence of the invention. The detergent according to the invention fully meets the requirements of biodegradability. The agent is a phosphorus-free product, it is not harmful to organic life in surface waters, has excellent washing and cleaning properties, and is also effective in neutralizing and strengthening. concrete surfaces, especially those exhibiting dustiness and high alkalinity, and perfectly removes grease. The essence of the invention consists in the fact that the active substance used is a mixture of 30-60 parts by weight of sodium hydroxycatrboxylic acid, 30-60 parts by weight of sodium metasilicate and 5-15 parts by weight of a non-ionic surfactant with an easy-to-use body. ¬ grading, possibly with the addition of 80-150 parts by weight of fine mineral filler, especially quartz or dolomite flour, acting as a scouring agent. The active ingredient is preferably a mixture in a weight ratio of 30 parts sodium tartrate and / or sodium citrate, 20 parts sodium metasilicate and 5 parts non-ionic surfactant, in particular alkylphenoxy polyoxyethylene ether. The effectiveness of the agent according to the invention consists in the simultaneous action of the alkylphenoxypolyoxyethylene ether, reducing the surface tension of the aqueous detergent solution and facilitating the wetting of the cleaned surfaces, along with the action of the ingredients, in the form of sodium metasilicate and sodium citrate, and a high capacity dispersibility All kinds of contaminants, which simultaneous action fixes these contaminants in the form of a colloidal suspension that does not adhere to the surface to be cleaned, as well as by the action of a scouring component in the form of a fine mineral filler, especially quartz and / or dolomite flour, which facilitates the removal of hardened substances that adhere firmly to the cleaned surfaces. These features make washing with the agent according to the invention a short-lasting and effective process, which also enables the neutralization and strengthening of the alkaline and dusty concrete substrate, thanks to the chemical reaction between sodium metasilicate and calcium hydroxide on the surface. the surface of the concrete element as well as in the outer layer of fresh concrete. As a result of this reaction, calcium silicate grains are formed on the surface and / or in the outer layers of the element, perfectly bonded with the outer layer of the element and binding loose dust grains, with the result that the alkaline concrete substrate is completely neutralized. Example 1 In order to obtain a washing-cleaning agent in the form of an aqueous solution, 650 liters of water are poured into a mixer provided with a slow-rotating mixer, to which 36.5 kg of sodium metasilicate pentahydrate and 54.5 kg of citrate are poured. sodium and 9 kg of octylphenoxy-22-oxyethylene ether. After dissolving these ingredients by mixing, a clear, translucent, slightly foamed detergent solution is obtained which can be used immediately. The use of the agent in house fibrils consists in carefully washing oily and dusty surfaces of concrete elements with a brush on a stick of soft, short hair, and then thoroughly rinsing the washed surface with water. Some home factories are equipped with facilities for mechanically washing and rinsing concrete surfaces with water. Example- II. To obtain a detergent in the form of a powder, 150 kg of quartz flour are poured into a mixer equipped with an anchor agitator with a planetary movement, and then slowly, gradually amidst mixing, 6 kg of molten nonyloferro ether are poured. - xy-8-oxyethylene. After the mixture has been thoroughly homogenized, 40 kg of fine crystalline sodium metasilicate and 60 kg of sodium tartrate are introduced into the mixer during further intensive mixing. After mixing these components for 5 minutes, a loose substance is obtained, which is dissolved in water in a weight ratio of 1 part to 10 parts of water before being used for cleaning sanitary equipment. Claims 1. Cleaning and cleaning agent containing sodium metasilicate, surfactants and other known additives, characterized in that the active substance is a mixture of 30-6097 243 parts by weight of sodium hydroxycarboxylic acid, 30-60 parts by weight sodium methosylate and 5-15 parts by weight of a readily biodegradable non-ionic surfactant, possibly with the addition of 80-150 parts by weight of fine mineral filler. 6 2. Measure according to arist. The process of claim 1, wherein the sodium salt of the hydroxycarboxylic acid is sodium tartrate and / or sodium citrate. 3. The measure according to claim The method of claim 1, wherein the mineral filler is quartz and / or dolomite flour. PL
