ANTIFREEZING AGENT AND DEPLETION PREVENTION AGENT FOR PLANT ANTIFREEZING AGENT FOR ROAD ANTIFREEZING AGENT FOR ARTICLE HEATING MEDIUM SOLUTION
안전하고, 봉수와 혼합하기 쉬우며 한랭지에서도 사용할 수 있는 동결방지제의 제공을 목적으로 한다. 요소와, 계면활성제와, 정제 글리세롤과, 물 또는 알칼리 환원수를 가지며, 정제 글리세롤은 에탄올과 유지와 물과 탄화물을 갖는 폐글리세롤을 증류정제한 것이며, 요소를 10∼15중량％ 함유하고, 전체의 pH를 9.0∼10.0으로 하는 것이다.
It is an object to provide a water vapor pressure lowering agent which is safe, is easily mixed with seal water, and is usable even in a cold region. The water vapor pressure lowering agent includes urea, a surfactant, purified glycerol, and water or alkaline reducing water, and the purified glycerol is obtained by purifying waste glycerol containing ethanol, an oil or fat, water, and a carbide by distillation. In a method for preventing seal breakage in a drain trap T by using the water vapor pressure lowering agent, the vapor pressure lowering agent is introduced such that a liquid level is equal to or higher than a seal water maintenance lower limit in a seal water portion of the drain trap T.
