Description
высокодисперсной кремниевой кислоты (средний размер первичных частиц 12 нм), Продукт сушат при 58°С в течение 30 мин в сушильном шкафу.
Полученный продукт имеет сйедующие результаты анализа: активный кислород 13,26, StOg 0,99, COg 26,53, FejO 0,003%, насыпной вес 1,030 кг/л хранении при 30°С, относительнойвлажности 92,9% спуст 4 дн потери активного кислорода составл ют 1,6%, спуст 7 дней - 6,8% и 10 дней8 ,4%.
При использовании перкарбоната натри с содержанием воды меньше 1% потери активного кислорода в течение 10 дней при 30°С и относительной влажности воздуха 92,9% достигают 23,8%, при содержании воды больше 10% потери активного кислорода снижаютс незначительно, но при этом по вл етс слабое комкование продукта. При размере частиц кремниевой кислоты более 100 нм потери активного кислорода возрастают более, чем на 20%,
при размере частиц ниже 2 нм не наблюдаетс снижени потерь.активного кислорода, получение кремниевой кислоты с размером частиц ниже 2 нм затруднительно .
Claims (1)
- Формула изобретениСпособ стабилизации перкарбоната натри путем смешени перкарбоната натри с соединением, содержащим крений ,, с последукнцей сушкой продукта, -отличающийс тем, что, с целью снижени потерь активного кислорода в продукте при его хранении , в качестве соединени , содержащего кремний, используют кремниевую кислоту с размером частиц 2-100 нм и на смешение подают перкарбонат натри с содержанием воды 1-10 вес.%.Источники информации, прин тые во внимание при зкспертизе1, Патент США № 3773678, кл. 252-186, опублик. 1973.
