In origin to points, oil is divided into two kinds, one is the "day after tomorrow", which is a synthetic heat transfer oil, the other is natural, that mineral type HTF. The use of high temperature thermal oil is very broad, ordinary people can not know, it is not enough popularity, universality YD350 HTF wholesale, so we need to promote it. In order to better conserve energy YD350 HTF offer, we better understand and study more HTF. The more people know it, it will be more extensive use of human beings out of the energy savings will be more YD350 conducting oil prices, leaving our children and grandchildren of the energy industry even more, high temperature heat transfer oil to the benefit of us and our future generations. HTF methods to identify quality Step 1: acid number of the acid value change HTF change occurs mainly in the expansion tank is not used blanketing system, it changes indicate that the degree of thermal conductivity aging solution. When the aging to a certain extent, and further polymerized to form a polymer soluble organic acid oxidation products, when the acid value may decrease. Therefore, the acid value is a measure of the degree of change is an important quality criterion HTF. Step 2: The flash point is a measure of change in the flash point of the main security HTF quality index, the flash point is to illustrate the possibility of volatile products and flammable gas formation. Step 3: Change change of attachment of the attachment is to account for changes in molecular weight and structure of the liquid heat transfer. HTF HTF would happen if the cleavage of the attachment itself decreases oxidative polymerization viscosity increases. For users who work low temperature environment, we are for conducting oil viscosity should pay attention to.
