Application: — in the industry: for cleaning of capacities of a scum, corrosion products; |
at catering establishments and in life: for processing of table and kitchen ware;
— by production of household chemicals: for use in compoundings of detergents, antinakipin, means for removal of a rust;
— in chemical industry as raw materials at synthesis of chemical means: for receiving fire - resistant materials, for decomposition of excess of nitrogenous acid in dinitriding processes, for receiving herbicides; — in galvanotechnics: for preparation of electrolytes, for etching of a food tin; — in system of water purification: for removal of slime from the water - cooling systems (in particular pools); — in pulp and paper industry: when cleaning papermaking machines; — in oil production: for processing of a bottomhole zone of oil wells for the purpose of increase in oil recovery of layer; — for washing of internal surfaces of the heattechnical equipment at combined heat and power plant.
Recommendations about application (approximate compounding):
- For removal of "a dairy stone" and a wash of pasteurization corrosion - proof devices, lamellar and tubular pasteurizers on milk - and creameries: in the form of 1,5 - 2,0% water solution at a temperature of 70 - 75 °C, time of washing of 30 - 40 minutes. Account norm: no more than 0,07 kg/t of milk.
- For removal of "a beer stone" prepare solution of sulfaminovy acid at the rate of 0,5 - 1,5 kg on 10 l of water, at a temperature of 50 - 60 °C. After careful hashing solution is applied on the surface of devices with formations of "a beer stone". If the layer of education exceeds 3 - 5 mm prepare the concentrated solution of sulfaminovy acid from 1,5 kg on 10 l of water, washing duration – 6 - 8 h. Upon termination of cleaning to wash out the device water.
- For removal of carbonate deposits (scum) from the heatexchange equipment, radiators, household ware, etc. : in the form of 2 - 3% solution with OP - 7 or OP - 10 (0,1% ) at a temperature of 70 - 75 °C, duration of washing is 7 h. After use of sulfaminovy acid, the equipment is washed out by water or 5/% solution of soda. Composition of flushing solution: water, sulfaminovy acid, corrosion inhibitor.
- For washing of the equipment at the enterprises of pulp and paper mill in the form of 10% solution at a temperature of 25 - 45 °C, washing duration ~ 2 - 5 hours before the minimum decrease in concentration of solution. Washing process – with circulation and without. After washing solution is dumped in the industrial sewerage. Solution is not reused.
Advantages of application:
- The fulfilled solution has the neutral environment and does not demand additional utilization.
2. Quickly dissolves carbonate deposits, a dairy and beer stone, disinfects the equipment.
3. Prost in use: it is easily dissolved in warm water, solution of acid does not cause burns.
4. Has the sparing effect on metal.
5. Sulfaminovy acid is produced in a dry crystal look that considerably simplifies and reduces the price of process of its transportation, storage and operation.
