(57) Abstract:Use: in the construction of gender in livestock pens for cattle. The purpose of the invention is to lend the composition of the floor bactericidal properties. The sex composition contains changeset, bitumen and bactericidal drug. Floors contribute to the improvement of sanitary conditions and provide comfort for the animals, as well as reduce the cost of care for livestock. table 2. The invention relates to the construction, namely the manufacture of floor plates for livestock buildings.Known heat mass for cooking plates (1), consisting of clay, limestone, bitumen. However, it is not intended for flooring livestock buildings as physical-mechanical indicators does not meet appropriate requirements for floors for animal welfare.Most highlight the technical nature of the invention, the composition for the manufacture of tiles for livestock housing (2).The composition comprises a porous filler changeset and additionally limestone in the following ratio of the components is the properties and does not create the necessary sanitary-hygienic conditions for cattle.Floors with germicidal properties, delay the growth of pathogenic and non-pathogenic microflora, which improves the sanitary condition of the air environment of the facility.The purpose of the invention provide compositions sex bactericidal properties.This objective is achieved in that the composition including sunyit, limestone, bitumen, further comprises a bactericidal drug in the following ratio of components, wt.Changeset 50-60

As a bactericidal drug is used performedat polymerization of formaldehyde (HCOH)n and contains not less than 95% Is white loose powder with a smell of formaldehyde. Perform one of the best disinfectants suitable for disinfection as in etiology and spore microflora, viruses and fungi. Approved for use as a disinfectant Main veterinary Department of the Russian Federation.The proposed arrangement would reduce the level of microbial contamination of the air environment in livestock buildings, improve the sanitary condition that will help reduce contamination of the LM is IMY comfort for the animals, and will also reduce the cost of care for cattle.The panels are as follows. The starting materials for the production of tiles on porous fillers are limestone of local origin, changeset, bitumen and bactericidal drug paraform. Dry powdery mixture of components from the drying drum enters the mixer. Received press weight by mixing the dry powder component is mixed with the bitumen. The main purpose of this process is the uniform distribution of the bitumen on the surface of grains of the mineral filler and getting press-weight, easy-to-formation.Preparation of press-weight is carried out in a twin-shaft mixers, where from the hopper flows dry mineral powder and batonrouge bitumen.The preparation cycle of the press mass 10-12 minutes At achieving uniformity of mass is discharged into the receiving hopper of the press. Prepared press the mass is poured into the cradle press, that is, making the reciprocating movement, the front wall relieves lower raised when the dies are pressed tiles and delivers it to the front Desk press and simultaneously produces the filling of the molds, press the St comes with a compaction factor of 1.7. The tiles shall be kept for 24 h until complete hardening of the bitumen. Tiles with a weight of 5 kg has the following dimensions: length 240, width 240, the thickness of 50.To achieve bactericidal activity in the press mass was introduced paraform in weight concentrations of 3 and 5%
Bactericidal activity floor samples studied by the method of diffusion in agar (MDA) in a dense nutrient medium with the test microbe Bac.subtilis strain AT CC 6633 (C. C. Dmitrieva, 1965).In Petri dishes were poured nutrient medium with spores of the test microbe. Then pour in the agar made holes with a diameter of 10 mm wells were made in 0.05 ml of an aqueous infusion (after soaking samples sex for 2 h). Another party cups on the surface of the agar with the test microbe was placed pieces samples sex 100 mg. Control served MPA+germ. Cups were placed in a thermostat with a temperature of 37oC. analysis was performed after 24 and 48 hoursBactericidal activity of samples sex also studied by the method of dilutions in liquid nutrient media.In test tubes containing 2 ml of a meat-peptone broth (BCH) and the samples were made in 0.2 ml 10 million daily suspended microbes (optical standard turbidity): Staph. aureus strain 209-P; Str. aga E. Li strain 0138. Control served BCH+germ. PST samples sex after their production after 16 months are given in table.1.Analysis of bactericides floor samples showed that the samples sex with Performa 3% at the end of time had lost its bactericidal properties, while at the end of time samples of the floor with 5% paraformal not lost its bactericidal properties.Physico-mechanical properties of boards made the prototype and the proposed composition with the addition of a bactericidal drug, is given in table.2.As can be seen from the data (table. 2), plates made of the proposed composition with bactericidal drug, according to the physical-mechanical characteristics are not inferior to the prototype, meet the appropriate requirements and have antibacterial properties.
