AGENT FOR LOWERING VAPOR PRESSURE OF SEALING WATER IN DRAIN TRAP METHOD FOR PREVENTING SEAL BREAKAGE IN DRAIN TRAP USING AGENT FOR LOWERING VAPOR PRESSURE OF SEALING WATER IN DRAIN TRAP ANTIFREEZING AGENT FOR WATER AND METHOD FOR PREVENTING SEAL BREAKAGE IN DRAIN TRAP USING ANTIFREEZING AGENT FOR WATER
안전하고, 봉수와 혼합하기 쉬우며 한랭지에서도 사용할 수 있는 물의 증기압저하제의 제공을 목적으로 한다. 요소와, 계면활성제와, 정제 글리세롤과, 물 또는 알칼리 환원수를 가지며, 정제 글리세롤은 에탄올과 유지와 물과 탄화물을 갖는 폐글리세롤을 증류정제한 것이다. 물의 증기압저하제에 의한 배수트랩(T)의 파봉방지방법에 있어서, 배수트랩(T)의 봉수부의 봉수유지하한치 이상의 액면이 되도록 증기압저하제를 투입한다.
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.
