Abstract
The invention discloses a cleaning agent for a cold rolled silicon steel plate; the cleaning agent mainly comprises the following components in parts by weight: 16-30 parts of sodium hydroxide, 42-58 parts of sodium silicate, 13-19 parts of sodium tripolyphosphate, 2-12 parts of low-carbon-chain fatty alcohol ether, and 0.3-0.8 parts of high-temperature strong base organic silicon de-foaming power. The cleaning agent for the cold rolled silicon steel plate, provided by the invention, can overcome the defects of poor cleaning effect, high energy consumption, easily occurrence of operation faults and the like, and has the advantages that the cleaning effect is excellent, the energy consumption is low, and the operation fault is not easy to cause.
Description
Technical field
The present invention relates to metallic substance cleaning technique field, particularly, relate to a kind of cold-rolled silicon iron clean-out system.
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 easily causes 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 greatly, easily causes the defectives such as operation fault.
Summary of the invention
The object of the invention is to, for the problems referred to above, propose a kind of cold-rolled silicon iron clean-out system, 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 cold-rolled silicon iron clean-out system, mainly comprise following component, and be expressed as with parts by weight:
Sodium hydroxide: 16 ~ 30 parts;
Water glass: 42-58 part;
Tripoly phosphate sodium STPP: 13-19 part;
The fatty alcohol-ether of low carbon chain: 2 ~ 12 parts;
High temperature highly basic organosilicon defoaming powder: 0.3 ~ 0.8 part.
Further, described high temperature highly basic organosilicon defoaming powder specifically comprises high temperature highly basic organosilicon defoaming powder T-20G.
Owing in the greasy dirt on the cold-rolled silicon iron, containing a small amount of vegetable and animals oils (or synthetic fat) and a large amount of mineral oil.Adopt the cold-rolled silicon iron clean-out system of various embodiments of the present invention, can overcome the defective that cleaning performance is poor in the prior art, energy consumption greatly, easily causes the operation fault, good with the realization cleaning performance, energy consumption is little and 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 the fatty alcohol-ether of low carbon chain as tensio-active agent, can reduce the surface tension of scavenging solution, increases surfactivity and the cleaning performance of scavenging solution;
⑸ utilize high temperature highly basic 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.
