Description

Description of the invention

The utility model relates to the field of chemistry, in particular to dry mixes, namely, to substances having the property of preventing cement-concrete from sticking to equipment used in construction, for example, texture molds, with the help of which a texture pattern is made on the surface of the product from cement concrete.

A known separating agent, which includes a filler, and as a filler, a substance or a mixture of substances is used, which has the property of preventing the equipment used in construction from sticking to the surface of still wet cement-concrete |11.

The disadvantages of the known separating agent include the fact that it only has the function of preventing adhesion to cement concrete (which is still wet) of equipment used in construction, for example, texture molds, with the help of which a texture pattern is made on the surface of a cement concrete product .

The closest technical solution, both in essence and in terms of the tasks solved in the useful model, which was chosen as a prototype, is a separating agent, which includes a filler, while the filler is made in the form of hydrophobic calcide or similar in terms of physical and mechanical properties properties of matter (21.

The disadvantages of the known release agent chosen for the prototype include the fact that it only has the function of preventing adhesion to the cement concrete (which is still wet) of the equipment used in construction, for example, texture forms, with the help of which a texture pattern is made on the surface of the cement-concrete product.

The useful model is based on the task of providing additional coloring of the cement-concrete surface with different color saturation by adding coloring pigments.

The essence of a useful model in a separating agent, which includes a filler, while the filler is made in the form of hydrophobic calcide or a substance similar in physical and mechanical properties, lies in the fact that it additionally contains a pigment with the following ratio of components, by weight. In: filler - 5) 50-9595, pigment - 5-5095.

A comparative analysis of the technical solution that is claimed with the prototype allows us to conclude that the separating agent that is claimed differs in that it additionally contains a pigment at the following ratio of components, wt. 90: filler - 50-9595, pigment - 5-50905. -

Thus, the claimed separation agent meets the "novelty" utility model criterion. Av

The essence of the useful model is explained with the help of illustrations, where Fig. 1 shows the composition of the separating agent that is claimed, according to the ratio of components (wt. 95) in the total volume of the substance, Figs. 2-7 show the stages of preparation of the separating agent that is claimed, with the use of components (compounds) included in its composition, Fig. 8-10 shows the diagrams of the use of a separating agent, which is claimed, to prevent adhesion to cement concrete (which is still wet) of equipment used in construction, for example, texture forms, with the help of which a texture pattern is made on the surface of a cement-concrete product.

The separating agent, which is claimed, is manufactured in industrial conditions as follows. "

The technology for preparing dry mixtures, namely, the separating agent (which is claimed), consists in the preparation of 50 materials, their dosage, forced mixing and packaging. The choice of mixer type and mixing time have a great impact on the quality of the separating agent. It is necessary for finely dispersed components

And" to use mixers of forced action, in which more intensive mixing is achieved with the help of rotating screws, paddles or other similar devices. The physical and mechanical properties of the separating agent are also affected by the mixing time. If the mixing time is insufficient, the homogeneity of the solutions deteriorates. The optimal duration of mixing depends on the composition of the separating agent (filler and pigment) and is selected experimentally. Special attention is paid to the mixing time when using av | dry mixtures (for example, when using hydrophobic calcide or substances similar in physical and mechanical properties, as well as pigments). 7 Production of the separation agent, which is applied for, is provided in the form of one of the options of the technological av! 20 processes, which may differ from each other in the sequence of technological operations - either in the order when the filler is poured first, and then the pigment, or the pigment, and then the filler, or in the variant when

The filler and pigment are poured into the cavity of the mixer in the variants defined above in smaller proportions with the gradual adjustment of the components to the percentage of mass determined by the technology of preparation of the separating agent.

As a variant of the technological process, the preparation of the claimed separating agent begins with the fact that the container (position 1) (see Fig. 2), for example, a mixer in which the claimed separating agent is prepared, is pre-filled according to the recipe filler (item 2) (which is made in the form of hydrophobic calcide or a substance similar in physical and mechanical properties - as a variant of the manufacturing process of the claimed substance) in the amount of 50-9595 from the total volume of the substance (see Fig. 3). Next, pigment (position 3) is added to the filler (position 3) (which is in container 1) in the amount of 60. B-BOFr from the total volume of the substance (see Fig. 4).

After performing the above-mentioned technological operations, the components (namely, filler (position 2) and pigment (position 3)) are thoroughly mixed (see Fig. 5-6) until a homogeneous mixture is formed (see Fig. 7), for example, by hand or with the help of mechanical devices (item 4) (ZI.

Next, the produced separation agent (position 6) is applied to the surface of the product (position 5) made of cement concrete, for example, on textured coatings made of cement concrete before applying a texture pattern on them using texture molds (position 7) (see fig. 8).

As a technological process, after applying a separating agent (item 6) to the surface of the product (item 5) made of cement-concrete, texture forms are installed on the specified surface of the product (item 7). Next, with the help of texture forms (position 7), a texture pattern (position 8) (see fig. 9) is applied to the surface of the product (position 5) made of cement concrete, followed by removal of the specified texture forms (position 7) from the surface of the product (position 5) ) (see Fig. 10). At the same time, texture forms (position 7) do not stick to the surface of the product (position 5) made of cement concrete (which is still wet).

The percentage content of the components (namely, the filler (item 2) and pigment (item 3)) in the total 70 volume of the separating agent varies depending on the required amount of background coloring of the surface of the cement-concrete product |Z.

Table 1 presents the components that serve to prepare the separating agent that is claimed, and which, with the appropriate combination (combination of components by weight, 95), is characterized by a minimal background (tone of saturation) of painting the surface of the cement-concrete product. mass, 90) substance properties) and (powdery)

Table 2 presents the components that serve to prepare the separating agent that is claimed, and which, with the appropriate combination (combination of components by weight, 90), is characterized by the maximum background (tone of saturation) of painting the surface of the cement-concrete product. From mass, 90)

Filler (in the form of hydrophobic calcide or similar physical and mechanical solid 5BO-70 - with drinking water (powder) -

Increasing the effectiveness of the separating agent, which is claimed, in comparison with the prototype, is achieved due to the addition of components, namely, pigments that serve to paint the surface of the product from cement concrete, and the optimal proportion of all constituent parts (components) of the separating agent to ensure the possibility of its use in conditions of industrial production, for example, of textured coatings, both at normal ambient temperatures and at elevated and reduced temperatures.
