The reached efficiency was expressed in expansion of temperature of application in range from 0° to -10°C in comparison with application temperature (as main component) chloride calcium (from -10°C and below). \u0000Besides, declared deicing means allows to reduce cost of production of PGM developed from local raw materials by 20-40%.","PeriodicalId":185137,"journal":{"name":"On-line Journal \"Naukovedenie\"","volume":"219 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124456475","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
