Description
Technical field
The present invention relates to vehicle paintwork technical field, relate in particular to a kind of paper tape filter paper cleaning equipment and method.
Background technology
Ability cathode electrophoresis is the coating process that body of a motor car manufacture generally adopts at present, is the Main Means that improves vehicle body service life (corrosion resistance).In this process, phosphatization is usually used as one critical process in pre-treatment, by coordinating of phosphating coat and electrodeposited paint film, can greatly improve electrodeposited paint film corrosion resistance.
(1) phosphating reaction mechanism
1, acid etching reaction
Metal surface and Phosphating Solution occur first to react be the acid etching reaction that some metal is got off from surface dissolution.The acid etching speed about 1g/m2-3g/m2 of different Phosphating Solutions to steel; While making phosphorization of thick film, acid etching reaction speed also requires much higher.Acid etching reaction is very important to forming film, because it not only can purify metal surface, but also can improve the attached outstanding power of paint film.In the time that acid etching reaction occurs, due to the dissolving of metal surface, so the free acid in the Phosphating Solution of abuts on surface is consumed, metal ion enters Phosphating Solution, and the metal ion type of dissolving in is relevant with handled base material.In Phosphating Solution, add the hydrogen generating when oxidation accelerator can reduce acid etching reaction:
Steel surface: Fe+2H+1+2Ox → Fe+2+2HOx
Surface of galvanized steel: Zn+2H+1+2Ox → Zn+2+2HOx
Aluminium surface: Al+3H+1+3Ox → Al+3+3HOx
2, phosphating reaction
Second reaction occurring in Phosphating Solution is phosphatization.Because the reduction of the free acidity on the interface at metal and solution, PH raise, metal cation just no longer exists with soluble ion form, after the phosphate reaction in they and solution with the form precipitated crystal of trbasic zinc phosphate in metal surface.
According to different processes, this crystal can have different the Nomenclature Composition and Structure of Complexes:
3Zn+2+2H2PO4-1+4H2O→Zn3(PO4)24H2O
2Zn+2+Fe+2+2H2PO4-1+4H2O→Zn2Fe(PO4)24H2O
2Mn+2+Zn+2+2H2PO4-1+4H2O→Mn2Zn(PO4)24H2O
2Zn+2+Mn+2+2H2PO4-1+4H2O→Zn2Mn(PO4)24H2O
3, slagging reaction
The metal ion (Fe+2) being dissolved down in acid etching reaction is for example, by the promoter in Phosphating Solution (sulphite/sulfate, chlorate, peroxide) oxidation and slagging precipitation, and not slagging of Zn+2 in phosphating reaction.Al3+ ion can use fluoride and form fluorine aluminium chromium complex, and this chromium complex can be with kryolith(ice crystal) form precipitation:
Fe+2H+1+2Ox→Fe+2+2HOx
Fe+2+H2PO4-1 → FePO4 (slag)+2H+
Al+3+6F-→AlF6-3
AlF6-3+3Na+ → Na3AlF6 (slag)
(2) phosphorizing residue removal technique
If too much phosphatization slag is removed not in time from tank liquor, not only can pollute Phosphating Solution, shorten its service life, also can be attached to surface of the work affects phosphorization film quality and final coating quality simultaneously; For spraying system, phosphatization slag too much easily causes the obstruction of nozzle, pipeline, reduce the heat transfer efficiency of heat-exchange system, cause whole production line normally to move, therefore must take feasible way the phosphatization slag content control in tank liquor within the specific limits, various phosphorizing residue removal systems are arisen at the historic moment thus.
The slag removing system of applying in actual production at present comprises: sloping plate deposition groove filtration system, and full dose filter-type slag removing system, applying in addition more slag remover has the equipment such as paper tape filter, plate and frame filter press and FK phosphatization filter press.
The paper tape filter paper specification that phosphorizing residue removal machine uses is: the series such as 650mm × 25m, 650mm × 50m, and after nonwoven transmission automatically, pressure filtration, the de-liquid of ventilation, filter residue is discharged automatically from machine, and nonwoven twists on spool in machine.Under normal circumstances, the confidential continuous operation in process of production of asking of phosphorizing residue removal, very large to the consumption of filter paper, and also complicated operation, cost is high, and operating efficiency is low.
Therefore,, for above deficiency, the invention provides a kind of paper tape filter paper cleaning equipment and method.
