Description
Изобретение относитс к химической промьшшенности, а именно к реагентам, примен емым при зимней обработке го- родских и автомобильных Дорог.The invention relates to the chemical industry, namely to reagents used in the winter processing of urban and automobile roads.
Цель изобретени - увеличение сцеплени колес автомобил с дорогой, понижение температуры смерзани и коррозионной активности препарата.The purpose of the invention is to increase the adhesion of car wheels to the road, lowering the freezing temperature and the corrosivity of the preparation.
Пример . Препарат готов т смешиванием компонентов в лабораторной мешалке до получени однородной смеси песка, фосфогипса и хлоридов щелочных и щелочноземельных металлов .An example. The preparation is prepared by mixing the components in a laboratory mixer until a homogeneous mixture of sand, phosphogypsum and alkali metal and alkaline earth metal chlorides is obtained.
Дл полученных смесей определ ют, угол внутреннего трени , характеризующий сцепление препарата с колесами идущего по дороге автомобил , температуру смерзани препарата при его йлажности 20Z и защитный эффект препарата от коррозии.For the mixtures obtained, the angle of internal friction, which characterizes the adhesion of the preparation to the wheels of the vehicle on the road, the freezing temperature of the preparation at its humidity of 20Z, and the protective effect of the preparation against corrosion are determined.
Данные измерений приведены в таблице.Measurement data are shown in the table.
Из приведенных в таблице данных следует, что уменьшение количества хлоридов менее 10% приводит к по- вьш1ению температуры смерзани препарата въте уровн известного препарата . Увеличение количества хлоридов вьше 20% за счет уменьшени количества песка приводит к сниже- (нию угла внутреннего трени нерастворимой части препарата ниже известного уровн , что ведет к снижению сцеплени препарата с колесами автомобил и увеличению тормозного пути.From the data in the table it follows that a decrease in the amount of chlorides of less than 10% leads to an increase in the freezing temperature of the drug at the level of the known preparation. An increase in the amount of chlorides above 20% due to a decrease in the amount of sand leads to a decrease in the internal friction angle of the insoluble part of the preparation below a known level, which leads to a decrease in the adhesion of the preparation to the wheels of the vehicle and an increase in the stopping distance.
Использование фосфогипса в количестве менее 5% не увеличивает защиту от коррозии, а угол внутреннего трени падает ниже изыестного уровн . Увеличение содержани фосфогипса выше 10% нарушает его оптимальное соотношение с песком, что приводит к падению угла внутреннего трени ниже известного уровн , что в свою.The use of phosphogypsum in an amount of less than 5% does not increase protection against corrosion, and the internal friction angle falls below the final level. An increase in the phosphogypsum content above 10% violates its optimum ratio with sand, which leads to a drop in the angle of internal friction below a known level, which is in its own.
