The present invention provides a pH stabilizing heat transfer medium composition comprising a main component of water, glycol, alcohol or glycol ether, and a pH buffer agent. The pH buffer agent is comprised of an alicyclic compound where a single ring-constituting carbon atom is bonded to two identical members or two different members selected from the group consisting of carboxymethyl and its salts, or where at least two ring-constituting neighboring carbon atoms are each bonded to a single member selected from the group consisting of carboxymethyl and its salts.
本发明提供了一种 pH 值稳定传热介质组合物,其主要成分包括水、乙二醇、醇或乙二醇醚以及 pH 值缓冲剂。pH 缓冲剂由脂环族化合物组成,其中单个构环碳原子与两个相同的成员或两个不同的成员键合,这些成员选自羧甲基及其盐组成的组,或者至少两个构环相邻碳原子分别与单个成员键合,这些成员选自羧甲基及其盐组成的组。
