Zusammenfassung: | The invention discloses a multifunctional neutralizing acid agent for a tunnel washing machine and a preparation process thereof. The neutralizing acid agent comprises the following components in percentage by mass: 1 to 5% of methylglycinediacetic acid trisodium salt, 2 to 6% of diethylenetriamine pentaacetic acid with a purity of 40%, 0.01 to 0.5% of a fluorescent brightener, 12 to 20% of sulfamic acid, 1 to 5% of citric acid, 1 to 5% of oxalic acid, 0.01 to 0.2% of hydrofluoric acid and 2 to 6% of ethanol, with the balance being deionized water. The multifunctional neutralizing acid agent for the tunnel washing machine is easy to prepare, practical to use, good in neutralizing efficiency and capable of rapidly and synchronously completing peracid neutralizing, softening, static electricity resisting and whitening treatment. The neutralizing acid agent provided by the invention neutralizes alkaline substances, can effectively remove calcium, magnesium, iron ions and other dirt deposits deposited on public t |
