Abstract
The invention relates to an environment-friendly comprehensive pretreatment agent. The environment-friendly comprehensive pretreatment agent consists of main materials, a surfactant and a complexing agent. Each liter of the environment-friendly comprehensive pretreatment agent contains the following components in part by weight: 700 to 800 grams of industrial hydrochloric acid, 10.0 to 14.0 gramsof acetic acid, 2.0 to 4.0 grams of polyethylene glycol, 2.0 to 4.0 grams of alkylsodiumsulfonate, 4.0 to 6.0 grams of triethanolamine, 3.0 to 5.0 grams of ethylenediamine tetraacetic acid tetrasodium salt, 7.0 to 10.0 grams of potassiumsodiumtartrate and the balance of water. The environment-friendly comprehensive pretreatment agent is prepared by weighing the components in the formula and stirring the components uniformly. In the environment-friendly comprehensive pretreatment agent, the surfactant is added, so the capacity of removing rust and oil dirt adhered to the surface of the metal is enhanced, the effect of treating the oil dirt is good, hydrochloric acid mist generated in the working process is reduced, the working environment is improved, and the service life of bath solution is prolonged.
Description
Technical field [0001] The invention relates to the field of chemical engineering, in particular to a comprehensive environmental protection comprehensive pretreatment agent before metal phosphating. Background technique [0002] The traditional pretreatment method for phosphating is usually direct treatment with industrial hydrochloric acid. Such treatment can only deal with newly formed rust. Due to the storage of metal materials and other reasons, the rust and oil stains on the metal surface are bonded together, which is difficult to clean. In view of the above situation, we invented this treatment agent formulation, which can overcome the shortcomings of traditional methods, introduce surface active substances, enhance the performance of environmental protection comprehensive pretreatment agent, and add a complexing agent to extend the tank The use time of the liquid. Summary of the invention [0003] In order to overcome the shortcomings of the prior art, the present inven...
