Abstract
The invention relates to metal acid cleaning addition agent integrated buffering erosion, restraining fog and environmental friend. Compared with limit of other product, this invention uses intermediate compound from petroleum cracking as main material, mixed with solvent, dispersant, emulsifier, and activator according to proportion. It relates to chemical cleaning, buffering erosion, chemical derusting and other application in metallurgical industry, chemical industry, power plant, large-scale circulating water system and others, convenient to use, saves steel and acid consumption, and decreases cost. This invention also relates to do not generate secondary pollution technique during applying process.
Description
Technical field
The invention relates to the metal pickling additive and the manufacturing technology that integrate inhibition, press down mist, environmental protection, particularly main raw material(s), manufacture method, the scope of application, manufacture course of products and user use the technology that does not produce secondary pollution in this product process.
Background technology
Present known iron and steel corrosion-retarding fog inhibitor weak point is to be limited to the metallurgy industry pickling additive, is only applicable to mineral acid, and its product starting material are mineral-type, and produce secondary pollution in the production process.
Summary of the invention
The present invention has overcome deficiency of the prior art, and its feature comprises starting material formation, manufacture method, the scope of application, is different from domestic like product.The present invention integrates inhibition, presses down mist, environmental protection metal pickling additive, and described product main raw material(s) is a petroleum cracking intermediate material, makes with solvent, dispersion agent, emulsifying agent, promoting agent preparation method in proportion.Described various organic acids or the inorganic acid fluid additive of being applicable to; Relate to chemical picklings such as metallurgy, chemical industry, oil, power plant, large scale industry circulating water system, boiler heat supply network and large-scale water system equipment, the chemistry inhibition, the zone of oxidation matting of the cold and hot rolled steel plate of the usefulness of Chemical Inhibition acid mist and chemical rust removing, chemical cleaning, chemical scale-inhibiting, especially metallurgy industry, steel pipe, wire rod, steel strand.Do not produce secondary pollution in user's use and meet national standard.The present invention brings economic benefit, social benefit and environmental benefit for manufacturing concern, user and society; Main raw material(s) constitutes, and manufacturing concern's cost is reduced, and manufacture method is easy not to produce secondary pollution.Applied widely, the user saves the steel consumption on the basis of ensuring the quality of products, save the acid consumption, reduces cost, and is easy to use, do not produce secondary pollution and meets national standard.The invention belongs to leading domestic product, obtain big Jinshi City State Scientific and Technological Commission " Tianjin section becomes mirror word S[2000] 2-142 number " appraisal of scientific and technological achievements certificate on October 23rd, 2000.
Embodiment
1, prepare solvent, petroleum cracking intermediate material, dispersion agent weighs up in proportion, and petroleum cracking intermediate material is pounded into fritter;
2, starting reactor stirs.Solubilizing agent 1 in reactor in proportion;
3, solubilizing agent 2 in reactor in proportion; (30 minutes)
4, promptly begin to heat up behind the adding solvent;
In reactor, add petroleum cracking intermediate material when 5, temperature rises to 50 ℃ in proportion, must progressively in still, add when adding petroleum cracking intermediate material, once all do not add, in 30 minutes, add;
6, continue to heat, stir, temperature keeps 60 ℃ ± 5 ℃, stirs 6 hours;
7, reactor stops heating, adds dispersion agent in proportion in reactor, and cooling is stirred and opened the discharging of reactor valve in 20 minutes simultaneously; (hereinafter referred to as mother liquor)
8, mother liquor is cooled to 40 ℃, begins to filter with 120 orders-140 mesh filter screen, and will store in the mother liquor tun;
9, production marketing carries out the timing of secondary still, and reactor starts stirring, adds mother liquor simultaneously on request.
10, in reactor, add emulsifying agent under the stirring at normal temperature in proportion.
11, add promoting agent in proportion.
12, normal temperature stirs and to go out still in 3 hours for following about 20 ℃, by barreled and weigh.
The present invention's products production per ton sees Table with material formula and processing requirement

| 2 | Solvent 2 | 120～200 | Begin after the adding to heat up and stirred 30 minutes, carry out next step when being warming up to 44 ℃, add petroleum cracking intermediate material process. |
| 3 | Petroleum cracking intermediate material | 150～250 | Chunky shape progressively adds under the continuously stirring situation, heat up and do not stop, in 30 minutes, add, continue to heat up, whipping temp keeps 60 ℃ ± 5 ℃, churning time 6 hours enters adding dispersion agent program. |
| 4 | Dispersion agent | 50～150 | Banking stops to heat, and adds dispersion agent, stirs 30 minutes cooling discharges simultaneously. |
| 5 | Discharging, load | 1010 | When temperature is reduced to 40 ℃, filter, slag tap about 10kg, surplus only 1000kg mother liquor with 120 orders-140 mesh filter screen. |
| 6 | Emulsifying agent | 5～30 | Get the 970kg mother liquor otherwise stop and stir, add emulsifying agent, promptly enter with the promoting agent operation after adding. |
| 7 | Promoting agent | 5～25 | Add after the promoting agent that continuously stirring went out still in 3 hours, every barreled 25kg under the normal temperature. |
