Nitrogen-free ash removal neutralizer as well as preparation method and application thereof

The invention provides a nitrogen-free ash removal neutralizer and a preparation method and a use method thereof.The nitrogen-free ash removal neutralizer comprises organic acid, inorganic acid, an oxidizing agent, a surfactant, a corrosion inhibitor and water, and the specific components are matched, so that the nitrogen-free ash removal neutralizer has the environment-friendly characteristic and the excellent ash removal effect; the environment-friendly problem caused by a nitric acid neutralizer is avoided, when the aluminum alloy product surface dust removing agent is used for removing dust on the aluminum alloy product surface after chemical polishing or alkali washing, dust can be rapidly removed, meanwhile, the corrosion amount of the aluminum alloy product is small, meanwhile, the cost is low, and the aluminum alloy product surface dust removing agent is suitable for industrial production and application. 本发明提供一种无氮除灰中和剂及其制备方法和使用方法，所述无氮除灰中和剂包括有机酸、无机酸、氧化剂、表面活性剂、缓蚀剂和水，采用上述几种特定组分进行搭配，使得所述无氮除灰中和剂具有环保特性和优异的
