I The tests were carried out on metal and wood test objects of size 10x10 cm. The test objects were contaminated with 2 billionth suspension of daily agar culture of Staphylococcus aureus (strain 209-P) at the rate of 1 ml of suspension per 100 cm g | surface (20 million microbial cells per j cm). All experiments were performed in triplicate.

: Infected test objects are treated with 6 and 10% hot (70-80 °) specimens of the Milling cutter at the rate of 0.5 l / m Once. The exposure is 3 and 1 hours, respectively. After the indicated exposure has passed, the test objects are treated with tap water at a rate of 0.5 l / m. ; Washes are taken with a sterile gauze swab, washed twice by centrifugation. Crops are carried out on MG1B with 5% sucrose. After one day, MPA was reassigned with 8.5% sodium chloride. The control is prepared in the same way prepared test objects that are treated with tap water at the rate of 0.5 l / m. Test tubes and cups with crops placed in a thermostat at 37 °. Records of the results are carried out after 48 hours. Crops are kept up to 7 days. The results of the experiments are presented in table. one.

The tests are carried out with the composition of 1 mi of the drug Milling cutter following, its composition (Table 2). In parallel, tests were conducted with the prototype drug caspos. The following composition, wt.%:

Tests are conducted on metal and wood test objects of size 10X.

X 10 cm. Test objects are contaminated with 2 billionth suspension of daily agar culture of Staphylococcus aureus (strain 209 - P) at the rate of 1 ml of suspension per 100 cm 5 of surface (20 million microbial cells per 1 cm). All experiments were performed in triplicate.

The test objects are treated with 6 and 10% hot (60-70 ° C) solutions of the Mill preparation at the rate of 0.5 l / m. 0 In this case, the exposure is 3 and 1 hour, respectively. Caspos is applied in the form of cold (18-20 ° C) 5-6% solutions at the rate of 1 l / m with an exposure of 1 hour.

g After expiry of the specified exposures, test objects are treated with tap water at the rate of 0.5 l / m. The control is prepared in the same way prepared test objects that are treated with tap water at the rate of 0.5 l / m. 0 Washings are taken with a sterile gauze pad, washed twice by centrifugation. Crops are carried out on BCH with 50% sucrose. After 1 day. reseeding was carried out in MPA with 8.5% sodium chloride.

Test tubes and plates with crops are placed in a thermostat at 37 ° C. Records of the results are carried out after 48 hours. Crops are kept up to 7 days. The results of the experiments are presented in table. 3. Samples of the following composition were tested (Table 4).

The tests are carried out with metal samples of galvanized steel and aluminum 50X30X2 mm in size, which are immersed in a solution of a means of 2% concentration (by preparation and total alkalinity) for 24 hours. In parallel, tests are carried out with the preparation of ethanol (prototype) of the following composition , wt.%:

Estimation of the corrosiveness of prog is reduced by the weight loss of the metal per surface unit (weight index). The test results are presented in Table. five.

6% hot (60-70 °) solution of the drug Milling cutter, applied once in,. a dose of 0.5 l / m at an exposure time of 3 hours ensures the disinfection of wood and metal surfaces infected with the culture of Staphylococcus aureus.

10% hot (60-70 °; solution of the Mill cutter, applied once in 5 doses of 0.5 l / m at an exposure of 1 hour, provides disinfection of wood and metal surfaces infected with the culture of Staphylococcus aureus.

The tested regimes can be recommended for disinfection of vehicles of category II (for production tests).

Hot (60-70 ° C) solutions of the compositions 2-5 6% concentration at an exposure of 3 hours and 10% concentration at an exposure of 1 hour when applied at a dose of 0.5 l / m provide decontamination of metal and wood surfaces contaminated with Staphylococcus aureus culture.

Hot (60-70 ° С) solutions of composition 1 under these conditions do not disinfect surfaces contaminated with Staphylococcus aureus.

5-6% solutions (18-20 ° C) of the preparation of the prototype Caspos with a flow rate of 1 l / m and an exposure of 1 h do not disinfect the surfaces contaminated with Staphylococcus aureus.

The cutter disinfectant has a weak corrosive effect on metals - galvanized steel and aluminum and can be recommended for disinfection.
