Description
Technical field
The present invention relates to technical field of industrial cleaning agent, more particularly to one kind is nontoxic, cleaning is simply environmentally friendly
Type composite stainless steel cleaning agent.
Background technology
The cleaning of industrial equipment is to reach the requirement of full production technological design, is to create good driving production bar
Part, ensure start-of-run and the necessary means that production is smoothed out.Remove the fouling in equipment, the dimension maintenance and expansion of in-service equipment
Build transformation to be required for carrying out industry cleaning link, so that its operation normally and efficiently.Domestic stainless steel equipment at present, is being constructed and put into operation
It is preceding with that will carry out oil removing, scale removal in maintenance, descale and the Chemical cleaning such as passivation protection is handled, generally lead to
Multiple steps such as degreasing, pickling, passivation are crossed to reach cleaning purpose.
It is than more typical cleaning process at present:
System leak detection → water flushing → degreasing → water flushing → pickling → water flushing → passivation → water rinses
→ dry.
Wherein, alkaline matter such as tertiary sodium phosphate, sodium hydroxide etc. typically are used during degreasing degreasing, acid cleaning process is general
Nitric acid, hydrofluoric acid, hydrochloric acid etc. are used, passivation can use nitric acid, nitrous acid etc..These materials inherently have certain corruption to equipment
Corrosion, toxicity is big and the processing of waste liquid is difficult, and the pollution to environment is very serious, as the use of nitric acid, natrium nitrosum can be
Poisonous oxides of nitrogen gas NO is produced in cleaning processX.Also, this technique needs to complete step by step in different systems clearly
Wash, process is quite cumbersome, can waste the resources such as more water, time, manpower.
As fully visible, a kind of nontoxic, novel environment friendly stainless steel cleaner is needed at present, cleaning process is not produced
Raw poisonous gas, do not pollute the environment, make cleaning simple, cleaning equipment will not be treated and cause corrosion to injure.
The content of the invention
