Abstract
The present invention relates to chemical paint and is especially one kind reagent painted to the metal surface to prevent splash. The splash preventing agent consists of rutile powder 10-20 wt%, calcium nitrate 1-6 wt%, iron-vanadium-aluminum powder 5-10 wt%, zinc oxide 2-8 wt%, ferric manganese phosphate 2-8 wt%, butyl cellulose 8-20 wt%, light calcium carbonate 2-8 wt% and modified ethanol 20-70 wt%. Applying the splash preventing agent makes the welded plane maintain smooth and no damage, and this can omit the polishing with grinding wheel after welding and ensure the reliability of ultraviolet detection.
Description
Technical field:
The present invention relates to a kind of chemical coating, preventing splash agent refers to a kind of reagent that metal solder rear surface splash prevents that is applied to.
Background technology:
Welding procedure is to use a kind of very widely technology in the modern industry.For example: marine ship, space flight and aviation, railway traffic, petrochemical industry, boiler vessel, five metals building or the like, the occasion of the welding that grows on trees.
When welding local melting metal; generally be two blocks of metals that welding rod, hope are connected; claim mother metal again, the three is melted in subrange, the gas that its mixture usually has ambient atmos or the non-metallic inclusion of sneaking into discharges; because of big electric current produces arc light high temperature; break out because of sharply heating up again, in the sound of a slice whip some liquid metals are thrown in the air, they are shinny because of high temperature; disperse everywhere, form so-called " weldering flower ".The splash that " weldering flower " produces when being welding.This three's liquid metal mixes rapidly under the effect of factors such as Van der Waals for, surface tension of liquid, molecular chemistry affinity, molecular thermalmotion extension mutually, combines together, and the middle part is in the majority with the welding base metal certainly.After the cooling, wish that two block plates that connect also just " have glued " together firmly, have reached the purpose of welding.When their contact mother metal steel plates, heat is passed to mother metal, make mother metal at contact point also fusing rapidly, splash mixes mutually with the mother metal liquid state, has promptly glued thereon firmly after the cooling.
Above-mentioned this splash is surprisingly many sometimes, and it makes the weld seam both sides close and numerous, and the diameter of pit is that the 0.1-5 millimeter does not wait.Self-evident, their harm is a lot, and this place only says a kind of: in order to guarantee welding quality, prevent because of welding seam breaking causes disaster, must need carry out ultrasonic examination in butt welded seam inside.Discovery must be rooted out, repair, in case future trouble after defectives such as crack, lack of penetration, not fusion, slag inclusion, pore are arranged.
The ultrasonic wave of checking usefulness generally adopts shear wave, injects from the mother metal surface of weld seam both sides, and fulsome spatter thing can't be placed ultrasonic probe, and inspection work can't be carried out.
At present, the method for industrial removal splash generally is to use grinder buffing.But polishing is a heavy physical labour, and heavy abrasive machine not only will be lifted in the position of facing upward of particularly polishing, and also will stand the infringement of dust.Even more serious is that last effect of polishing is also unsatisfactory, and the mother metal that not only frayed, surface of steel plate also grind ruggedly, crude injustice.Carry out Ultrasonic Detection on such surface, not only can damage expensive probe, and rough surface also can consume ultrasonic energy in a large number, the sensitivity of Ultrasonic Detection is reduced greatly, these defect risks can not find that consequence also is inconceivable.
Do not adopt the way of polishing, also nobody proposes at present, also can not in some authoritative standards such as International Institute of Welding (IIW) and U.S. ASME 1998 BOILER AND PRESSURE VESSEL CODESection IX-Welding, have to propose polishing, it seems that polishing is the way that is not able to.
Summary of the invention:
Technical problem to be solved by this invention be prevent since in the welding process weldering flower splash cause, splash sticks to the technical problem on mother metal surface.
The invention provides a kind of splash-proof welding agent, its characteristics are that the percentage by weight of the composition of this reagent is:
Golden red stone flour 10～20% calcium nitrate 1～6%
Ferrovanadium aluminium powder 5～10% zinc oxide 2～8%
Phosphoric acid ferrimanganic 2～8% butyl celluloses 8～20%
Light calcium carbonate 2～8% modification ethanol 20～70%
The preparation method of this reagent is:
(1), take by weighing each raw material, and with each composition mix mutually successively by said ratio;
(2), mixture injected sand mill grind, grind size requires can be just qualified by 320 hole purpose screen clothes, gets product after the sieving;
The using method of splash-proof welding agent of the present invention is:
(1), adopt the mode of brushing to construct, after splash-proof welding agent of the present invention is fully shaken up, get final product with the hairbrush brushing;
(2) adopt the mode of spraying to construct, splash-proof welding agent of the present invention is poured in the pressurized tank, add again and fill propellant and make aerosol product and can use.
Above-mentioned using method, splash-proof welding agent of the present invention is applied to behind the weld seam both sides soon will drying and forming-film, can carry out welding operation.
Adopt splash-proof welding agent provided by the invention, spraying or brushing form layer protecting film on the mother metal surface of weld seam both sides before welding procedure, intercept the adhesion between weldering flower and the mother metal during welding.When the lower granule weldering flower of temperature splashes down, directly intercepted, tumble then and there; When the higher big grain weldering flower of portion temperature splashes down, although it diaphragm has been dissolved, owing to the physicochemical property of the composition of diaphragm and mother metal " moistening " not mutually; can not form molten condition; still each self-separation after the cooling as long as sweep gently, just can be removed.
Prove that through mechanical test and Non-Destructive Testing butt welded seam quality of the present invention does not constitute illeffects.By using and not using sample of the present invention to compare, the mechanical strength of weld seam does not have anything to change, all class defectives such as additionally not generating pore, slag inclusion, crack yet, merge, be lack of penetration.
Adopt splash-proof welding agent of the present invention, the way of having removed from grinder buffing removing spatter thing has not only alleviated labour intensity, avoided the dust injury, but also do not damage mother metal, guarantee that its surface is still as before smooth, help carrying out ultrasound examination, thereby guaranteed the reliability of Non-Destructive Testing.
