Abstract
The invention discloses a phosphorus-free heavy oil cleaning method and an application thereof. The method comprises the steps of adding a cleaning agent and an auxiliary agent according to a proportion of 0.5-5% in a cleaning container and immersing for 10-20 minutes, wherein the cleaning agent is octylphenol polyoxyethylene ether; and the auxiliary agent is sodium silicate. The phosphorus-free heavy oil cleaning method can clean the heavy oil dirt on the surface of a metal workpiece rapidly, is degradable in water, can increase cleaning speed, and is safe, environment-friendly and phosphorus-free.
Description
Technical field
The present invention relates to the environment-friendly cleaning agent technical field, particularly is a kind of purging method for clean metal surface heavy oil dirt.
Background technology
Along with the develop rapidly of China's metalworking industry, the market demand of metal cleaner is very large.The heavy oil dirt of metallic surface is difficult the removing extremely, and now widely used industrial heavy oil cleaning agent is that highly basic contains phosphorus product mostly, and life-time service can cause red tide or blue bath phenomenon.
Summary of the invention
The heavy oil that the present invention seeks to environment-friendly cleaning agent and biodegradable clean-out system are applied to the clean metal surface is dirty.
The present invention mainly adopts the principle that saponification is decomposed and dissolving combines, and the heavy oil dirt of metallic surface can be decomposed, and accelerate peeling rate.Amount is dissolved in water by 3～5% during use, and metal works is invested in the tank, soaks 10～20 minutes.
Without phosphorus heavy oil purging method is to add clean-out system and auxiliary agent by 0.5～5% proportioning in clean container, soaks 10～20 minutes.
Described clean-out system is polyoxyethylene octylphenol ether.
Described auxiliary agent is water glass.
The mass ratio of described clean-out system and auxiliary agent is 5～50:0.1～2.
It is FAL:10～16pt that without phosphorus heavy oil purging method is applied to the straight carbon steel processing parameter; TAL:19～22pt; Treatment temp: 5～55 ℃.
It is FAL:8～12pt that without phosphorus heavy oil purging method is applied to the parts of stainless steel processing parameter; TAL:17～20pt; Treatment temp: 5～45 ℃.
It is FAL:3～6pt that without phosphorus heavy oil purging method is applied to the aluminium alloy processing parameter; TAL:4～11pt; Treatment temp: 5～25 ℃.
The without phosphorus heavy oil purging method of the present invention, the heavy oil that can remove fast surface of workpiece is dirty, and degradable in water not only can improve cleaning speed, and safety, environmental protection, without phosphorus.
Embodiment
The below is further explained explanation to the present invention.
Embodiment 1: the cleaning embodiment of straight carbon steel
With pressing 3～5% proportionings in the 1000L rinse bath, add 30～50kg polyoxyethylene octylphenol ether, the 2kg water glass is thrown in the straight carbon steel parts wherein, stirs and can use.
