Abstract

The invention discloses engine pedestal trial run liquid, which comprises the following components in percentage by weight: 25-90% of propylene glycol, 2-50% of water, 0.1-10% of triethanolamine, 0.1-10% of metal ion chelant, 0.1-10% of anticorrosive, 0.1-5% of scale prevention agent, 0.1-5% of cleaning dispersing agent, 0.01-0.1% of defoaming agent, 0.1-3% of bactericide and 0.01-0.1% of methyl red dye. The engine pedestal trial run liquid is compounded with balanced inorganic and organic antirust and anti-corrosion systems, is capable of preventing corrosion, rust, cavitation and boiling, has the advantages of high chemical stability, good compatibility with antifreeze liquid, long antiseptic period, long use efficiency, low toxin and environment protection. Meanwhile, non-metal materials can be effectively prevented from aging or hardening. Due to a silicon-free formula, silicate can be effectively prevented from gumming or precipitating. Because the engine pedestal trial run liquid is provided with various antiscale clean additive, the engine pedestal trial run liquid can perform the action on preventing, inhibiting and removing scales, and a cooling system is effectively kept clean and stable.

Description

technical field [0001] The invention relates to an engine test run fluid, in particular to a test run fluid used for engine cooling systems in the start test process, especially suitable for marine engines, vehicle engines and engine cooling systems for engineering machinery. Background technique [0002] The cooling media commonly used in domestic engine cooling systems are mostly low-molecular alcohols such as methanol and ethylene glycol, which are not environmentally friendly, have poor biodegradability, and have a short service life. Especially chemical raw materials containing silicates, amine salts, nitrites, etc., which are prone to precipitation and carcinogens. [0003] The United States, Japan and other countries have successively pointed out that the compound use of amino alcohol and nitrite will generate nitroamine carcinogens. The biodegradability of alcohol is worse than that of propylene glycol. In Europe, Japan and other countries, the main material of cool...
