Abstract
The invention discloses a normal temperature bonderite for renovating flow string. The normal temperature bonderite for renovating flow strings is prepared from the following raw materials in percentage by weight: 18-48 percent of phosphoric acid (with the concentration of 85 percent), 0.4-0.8 percent of citric acid, 1.8-2.6 percent of tartaric acid, 1.5-1.8 percent of zinc phosphate, 1.2-2.0 percent of zinc oxide, 1.5-2.5 percent of manganese nitrate, 0.1-0.8 percent of nickel nitrate, 1-4 percent of potassium chlorate and the balance of water. A parkerising layer with the standard quality can be generated at a normal temperature without heating even in cold winter, thereby realizing the transition of an old flow string renovating and parkerising process from heating to a normal temperature. The invention achieves the aims of saving energy and reducing emission, has simple process, convenient operation and stable parkerising production quality, saves the energy cost by 0.7-0.8 million yuan every year, remarkably decreases the production cost and improves the economic benefits.
Description
Technical field
The present invention relates to a kind of phosphorization agent and manufacture method, especially a kind of phosphating reaction speed is normal temperature bonderite for renovating flow string and the manufacture method of reaction soon and at normal temperatures.
Background technology
Oil field used iron and steel oil pipe in exploration, exploitation, oil production technology process, its outer wall need stand the corrosion of acidity or alkaline soil and moisture content and the erosion of microorganism, and its inwall need stand that moisture chloride in the crude oil corrodes and the abrasion of silt particle.Corrosion even perforation phenomenon will appear along with the prolongation of working hour in some anti-corrosion pipe, cause huge financial loss not only for the oil recovery in oil field, and the normal production in oil field in serious threat.Therefore, in order to reduce input, to shorten the off-time, reduce production costs and save metals resources etc., just need regularly old oil pipe with the oil field from underground taking-up, adopt suitable process of surface treatment to renovate reparation.At present, domestic and international application is a lot of in the processing method of the old pipe reparation renovation of recovering the oil, if any being coated with extruding process, clinkery epoxy powder inner coating process, liquid epoxy coating inner coating process etc. in frp lining technique, the HML, but, use coating process wider or that oil pipe inside and outside wall shot blasting on surface → phosphatization → anticorrosion with painting is wear-resisting.Concrete operation step is: the inside and outside mechanic shot peening → drill traverse of old pipe alkaline degreasing → drill traverse hot water wash → drill traverse heating acid pickling and rust removing → drill traverse washing → drill traverse neutralization → drill traverse washing → drill traverse phosphatization → drill traverse washing → drill traverse hot water wash → oven dry → spray-coating of heating of heating.Whole pretreatment line has nine cell bodies, wherein has five cell bodies to adopt high temperature and the heating of middle temperature, and the problem of bringing thus is as follows: the one, and energy-output ratio is quite large, and annual energy expenditure consumption is about 60 ~ 800,000; The 2nd, it is too many to produce phosphating dregs, all wants weekly tank liquor of overturning to remove, and not only dropping into a large amount of labor forces increases the heavy work amount, causes simultaneously the loss of phosphatization working fluid; More distinct issues are that the phosphorized waste water that contains phosphate radical, Vanadium Pentoxide in FLAKES, heavy metallic salt discharges in a large number, to environment.
Summary of the invention
The present invention is in order to solve the existing above-mentioned technical problem of prior art, to provide a kind of phosphating reaction speed soon and normal temperature bonderite for renovating flow string and the manufacture method of at normal temperatures reaction.
Technical solution of the present invention is: a kind of normal temperature bonderite for renovating flow string is characterized in that raw material and weight percent are as follows:
Phosphoric acid (concentration 85%) 18 ~ 48%
Citric acid 0.4 ~ 0.8%
Tartrate 1.8 ~ 2.6%
Zinc phosphate 1.5 ~ 1.8%
Zinc oxide 1.2 ~ 2.0%
Manganous nitrate 1.5 ~ 2.5%
Nickelous nitrate 0.1 ~ 0.8%
Potcrate 1 ~ 4%
Water surplus.
A kind of manufacture method of above-mentioned normal temperature bonderite for renovating flow string, it is characterized in that carrying out as follows: will measure 1/2 water and join in the reactor, stir take the speed of rotating speed as 150 rev/mins at normal temperatures and pressures, the nickelous nitrate, citric acid and the tartrate that add successively while stirring metering, after fully dissolving, the phosphoric acid that adds successively again metering stirs take rotating speed as 200 rev/mins of continuation; And successively with the zinc oxide of metering and zinc phosphate slowly adds wherein and fully stirring and dissolving be transparence, manganous nitrate and the Potcrate with metering adds wherein stirring and dissolving again, adds at last remaining 1/2 water yield, is stirred to solution and is green transparent liquid.
Even the present invention also need not heating in the winter of cold, can generate again the phosphorization membrane of requisite quality under the normal temperature, the anti-decayed and outmoded pipe renovation phosphating process of having realized recovering the oil is from being warmed to the transition of normal temperature.The concrete technology that application the present invention renovates flow string is mechanic shot peening → drill traverse normal temperature alkaline degreasing → drill traverse washing → drill traverse normal temperature acid pickling and rust removing → drill traverse washing → drill traverse neutralization → drill traverse washing → drill traverse normal temperature phosphating → drill traverse washing → drill traverse water conditioner washing → oven dry → spray-coating inside and outside the old pipe, reached the purpose of energy-saving and emission-reduction, technique is simple, easy to operate, the phosphatization quality of production is stable.The annual energy expenditure of saving has reduced production cost significantly at 70 ~ 800,000 yuan, has improved economic benefit.
