Abstract
The invention discloses a washing liquid for cleaning a cold-rolled silicon steel plate. The washing liquid mainly comprises the following components in parts by weight: 20-30 parts of sodium hydroxide, 43-58 parts of sodium silicate, 14-21 parts of sodium tripolyphosphate, 2-6 parts of soap and 0.1-0.6 part of general organosilicone defoaming powder. The washing liquid for cleaning the cold-rolled silicon steel plate can overcome the defects that in the prior art, washing effect is poor, energy consumption is large, operation fault is easy to cause and the like, so as to achieve the advantages that the washing effect is good, energy consumption is small, and operation fault is difficult to cause.
Description
Technical field
The present invention relates to metallic substance cleaning technique field, particularly, relate to a kind of scavenging solution for cleaning cold-rolled silicon iron.
Background technology
Because silicon steel sheet will use ROLLING OIL in cold-rolled process, so that the cold-rolled silicon iron surface is stained with one deck greasy dirt, this layer greasy dirt must clean up before annealing, to avoid silicon steel sheet greasy dirt carbonization in annealing process, the silicon steel sheet surface is polluted, affect the subsequent handling coating quality.
Usually, cold-rolled silicon iron surface and oil contaminant alkaline cleaner commonly used cleans.But these clean-out systems are bad to the cleaning performance of cold-rolled silicon iron, and one deck greasy dirt is usually also adhered on the cold-rolled silicon iron surface after the cleaning, cause the cold-rolled silicon iron surface after the annealing to form the carbonaceous stain, seriously affect the quality of surface of steel plate.And the working temperature of these clean-out systems is higher, and energy consumption is large during cleaning, and causes easily the e-quipment and pipe fouling and blocking pipe, and impact is normally produced.In addition, all do not contain defoamer in these clean-out systems, can produce a large amount of foams in to the cleaning process of cold-rolled silicon iron, these foams gently then pollute operating environment, and are heavy then production can not normally be carried out.
In realizing process of the present invention, the contriver finds to exist at least in the prior art that cleaning performance is poor, energy consumption causes the defectives such as operation fault greatly, easily.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of scavenging solution for cleaning cold-rolled silicon iron, to realize that cleaning performance is good, energy consumption is little and to be difficult for causing the advantage of operation fault.
For achieving the above object, the technical solution used in the present invention is: a kind of scavenging solution for cleaning cold-rolled silicon iron, mainly comprise following component, and be expressed as with parts by weight:
Sodium hydroxide: 20 ~ 30 parts;
Water glass: 43-58 part;
Tripoly phosphate sodium STPP: 14-21 part;
Soap: 2 ~ 6 parts;
General organosilicon defoaming powder: 0.1 ~ 0.6 part.
Further, described general organosilicon defoaming powder specifically comprises general organosilicon defoaming powder T-20GB.
Owing in the greasy dirt on the cold-rolled silicon iron, contain a small amount of vegetable and animals oils (or synthetic fat) and a large amount of mineral oil.Adopt the scavenging solution that is used for cleaning cold-rolled silicon iron of various embodiments of the present invention, can overcome the defective that cleaning performance is poor in the prior art, energy consumption causes the operation fault greatly, easily, to realize that cleaning performance is good, energy consumption is little and to be difficult for causing the advantage of operation fault; For example:
⑴ can utilize on sodium hydroxide and the cold-rolled silicon iron a small amount of that saponification reaction occurs vegetable and animals oils (or synthetic fat), generates soap and glycerine, and soap and glycerine can be dissolved in the scavenging solution well, thereby the vegetable and animals oils on the cold-rolled silicon iron is removed;
⑵ can utilize the emulsifying effect of water glass, effectively removes mineral oil a large amount of on the cold-rolled silicon iron;
⑶ utilize calcium ion and the magnesium ion generation complexing action in tripoly phosphate sodium STPP and the hard water, and complexing is dissolved in other metal ion in the scavenging solution, washes simultaneously the silicon dioxide film on cold-rolled silicon iron surface off, to improve cleaning performance;
⑷ utilize soap as tensio-active agent, can reduce the surface tension of scavenging solution, increases surfactivity and the cleaning performance of scavenging solution;
⑸ utilize general organosilicon defoaming powder as defoamer, can effectively eliminate the foam that produces in the cleaning process, avoids polluting operating environment, also to normally ensureing to some extent of producing.
Other features and advantages of the present invention will be set forth in the following description, and, partly from specification sheets, become apparent, perhaps understand by implementing the present invention.
Below by embodiment, technical scheme of the present invention is described in further detail.
