Description
Technical field
Explosion suppresion surface treatment process technical field of the present invention, is specifically related to a kind of explosion suppresion surface phosphorization treatment process of electric installation and the Phosphating Solution using.
Background technology
Along with the raising of development in science and technology and industrialization product requirement, the external coating that is used in the electric installation under mine has higher requirement, owing to being subject to the erosion of the obnoxious flavour adulterating in down-hole damp atmosphere and air, the surface of electric installation is not in long-time, its explosion suppresion surface just can produce chemical transformation, be that explosion suppresion surface there will be corrosion, performance reduces, even there is losing explosion prevention function, have influence on the safety in production under mine, existing processing mode is to plate the metal levels such as zinc to carry out antirust at explosion suppresion surface, corrosion, but this kind of complex process, production cost is high, cycle is long, although also there is the bonderizing mode of adopting, but its effect is not very desirable.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, provide a kind of and effectively prevent explosion suppresion surface corrosion and can extend explosion suppresion surface and the explosion suppresion surface phosphorization treatment process of respective electric service life of equipment and the Phosphating Solution using.
The present invention is achieved through the following technical solutions:
Explosion suppresion surface phosphorization treatment process, comprises the steps,
The first step, preparation phosphatization slurry:

26H
2o790-810 gram, pours in plastic containers and is in harmonious proportion;
(9). the Phosphating Solution that above eight steps are prepared adds furnishing starchiness in talcum powder;
Second step, brushes on explosion suppresion surface with the Phosphating Solution preparing, and thickness is no less than 2mm;
The 3rd step, guarantees Phosphating Solution slurry residence time on explosion suppresion surface according to envrionment temperature by following standard:
(1). more than envrionment temperature 30C °, the residence time 25-35 minute of Phosphating Solution slurry on explosion suppresion surface;
(2). envrionment temperature 25C °～29C °, the residence time 55-65 minute of Phosphating Solution slurry on explosion suppresion surface;
(3). envrionment temperature 15C °～24C °, the residence time 115-125 minute of Phosphating Solution slurry on explosion suppresion surface;
(4). envrionment temperature 1C °～14C °, the residence time 175-185 minute of Phosphating Solution slurry on explosion suppresion surface; (5). below envrionment temperature 0C °, the residence time 235-245 minute of Phosphating Solution slurry on explosion suppresion surface;
The 4th step, wipes the Phosphating Solution slurry on explosion suppresion surface, and explosion suppresion surface completes bonderizing, on explosion suppresion surface, forms one deck phosphatize phosphate coat.
If detect, bonderizing is off quality, and need to adopt concentration is that the hot sodium hydroxide solution of 15%-20% is cleaned, and again carries out phosphatization according to above-mentioned steps after removing underproof phosphatize phosphate coat.
Explosion suppresion surface after phosphatization is carried out to quality test, explosion suppresion surface surface sediment-free, rusty stain, phosphatization less than blank; And adopt 2%-5%NaCl solution to be coated on phosphatize phosphate coat, and under room temperature state, flood 110-130 minutes, do not occur that rust spot is qualified.
On explosion suppresion surface after bonderizing, coat slushing oil.
Before phosphatization slurry is coated to explosion suppresion surface, need to be to explosion suppresion surface processing of rust removing, oil removal treatment; Processing of rust removing is with oil or the above sand papering processing of 400#, shows uniform metalluster to explosion suppresion surface surface; Oil removal treatment is for soaking non-leaded gasoline or the wiping of 200# solvent oil with absorbent cotton.
In explosion suppresion surface oil removal treatment, after absorbent cotton is wiped examination on explosion suppresion surface, nothing turns black; Before phosphatization slurry is coated to explosion suppresion surface, the phosphatization slurry that soaks preparation with cotton yarn is all wipings on explosion suppresion surface, check that it is that Phosphating Solution configuration is qualified that explosion suppresion surface is light red, if gray or black gray expandable, dark vermilion red are not good, need add phosphoric acid to allocate again.
For the parkerized Phosphating Solution of explosion suppresion surface, by following composition,
10 kilograms, the warm water of 35C °-45C °; The ventilation breather CuCO of 60-80 gram
3cu (OH)
