Description
Technical field
The present invention relates to a kind of anti-corrosion product and technology, particularly a kind of anti-corrosion resin of preparing phosphoric acid by solvent extraction and production method thereof and purposes.Belong to chemical technology field.
Background technology:
In traditional phosphoric acid by wet process factory, use many, such as rubber, plastics, impermeable graphite, general universal resin, special stainless steel (316L, 904L) or the like material, because they are during as inner lining material or material of main part, tolerate comparatively single corrosive environment, can not influence quality product, so be the leaching that to satisfy phosphoric acid by wet process, concentrate and produce phosphate fertilizer or the like and require the slight corrosion of equipment.But, factory the inside at the refining phosphoric acid by wet process of solvent extration, because can't satisfy the corrosion-resistant requirement to phosphoric acid, sulfuric acid, etching acid and extraction agent simultaneously, the use of these materials brings the corrosion of equipment, will cause the product industrial phosphoric acid seriously defective.Such as, do the liner of equipment with rubber, plastics or general universal resin, can be extracted solvent swell, cause inner lining material distortion, lose strong, peel off, some in addition dissolved.And the resin for as dihydroxyphenyl propane, furans, these several classes of phenolic aldehyde not only is unable to undergo the corrosion of solvent, also can not stand corrosion equally in containing hexafluorophosphoric acid.Though the Resbon block excellent anti-corrosion performance,, they are by phenolic aldehyde or furan mastic joint filling and collude embedding, and these two kinds of clay are the corrosive that are unable to undergo extraction agent.Special stainless steel 316L is the corrosive that is unable to undergo phosphoric acid in the time of 〉=65 ℃.In the technology of wet phosphoric acid refining, it is very high requiring for the control of various impurity.Such as, the content of iron ion and heavy metal must not be above 0.005% in the product industrial phosphoric acid.This just requires very high to the protection against corrosion of equipment.Rubber, plastics, general universal resin and the seam crossing of graphite block are corroded, and liner body material (as carbon steel) also is corroded, and cause iron ion to be brought in the product industrial phosphoric acid.Special stainless steel 316L is corroded, and except bringing iron into, also brings heavy metals such as chromium, manganese, molybdenum into, causes the defective of product industrial phosphoric acid.Though 904L can satisfy the corrosion of tolerate P-levels acid, sulfuric acid, etching acid, organic solvent simultaneously, its price is very expensive, and 145 yuan/Kg is 3 times of resin material price of product of the present invention, with 24 times of resin material expense under the volume.
Summary of the invention
Goal of the invention of the present invention is at above-described problem, and by a series of corrosion-resistant experiments, exploitation has obtained a kind of resin, and it can be in the application under the phosphoric acid by wet process extraction system, and cost is low, good corrosion resistance.
In numerous impregnating material, vinyl ester resin also has the operative weldability of unsaturated polyester resin excellence except keeping or having surpassed the performance of Resins, epoxy aspect mechanical property, electrical property, cementability and chemical-resistant.Good as chemical resistant properties, especially powerful oxidation corrosion resistance acid and solvent resistance are good; Have good adhesiveproperties, the mechanical property height, resistance to fatigue is good or the like.
Vinyl ester resin can carry out esterification by Resins, epoxy and monobasic unsaturated carboxylic acid (vinylformic acid or methacrylic acid) and obtain.Phenolic aldehyde epoxy vinyl ester resin wherein, phenol aldehyde modified vinyl ester resin and high crosslink density type vinyl ester resin are adapted at the anticorrosion application under phosphoric acid, sulfuric acid, etching acid and the organic extractant environment.
As the equipment liner time, need carry out sandblasting to the steel matrix surface, remove iron rust and remove surface and oil contaminant, be beneficial to the adhesion of resin.Being coated with one deck resin primer earlier on treated matrix, being coated with structural sheet again after solidifying, is that the 0.2mm glasscloth alternately pastes with thickness, and gel content is about 50%, and thickness is about 2mm; Be exactly impervious barrier then, strengthen gel content 70%, thickness 1.6mm by chopped mat; Be anticorrosion layer then, by surperficial felt enhanced resin-rich layer, gel content 90%, thickness 0.4mm; Outermost layer then is to paste with resin.
When using mould to make, paste with resin earlier, be anticorrosion layer then, be by surperficial felt enhanced resin-rich layer, gel content 90% is exactly impervious barrier then, strengthened by chopped mat, gel content 70% is exactly to be coated with structural sheet then, with thickness is that the 0.2mm glasscloth alternately pastes, and gel content is about 50%, is exactly thereafter impervious barrier, strengthened by chopped mat, gel content 70% is anticorrosion layer then, by surperficial felt enhanced resin-rich layer, gel content 90% then is to paste with resin at last; Need to adjust the thickness of structural sheet, impervious barrier and anticorrosion layer according to finish size.
