Abstract
The invention discloses a process for carrying out rustproof treatment on a screwed nipple of a liquid accumulator and belongs to the technical field of a rustproof process. The existing process for carrying out rustproof treatment on the screwed nipple of the liquid accumulator has the defect of poor rustproof effect when the screwed nipple is stored for a long time or is transported. The process disclosed by the invention comprises the following steps of: firstly, coating antirust fluid on the screwed nipple; secondly, carrying out parkerizing on the screwed nipple of the liquid accumulator; thirdly, carrying out plastic spraying treatment; fourthly, carrying out roasting treatment; fifthly, coating the antirust oil fluid on the screwed nipple again; and finally standing for 24 hours to obtain a finished product. By the treatment process disclosed by the invention, the obtained product is difficult to rust in the long storage or transportation time.
Description
Technical field
The present invention relates to a kind of anti-corrosion treatment process to the reservoir nipple, belongs to the anti-corrosive technology technical field.
Background technology
The nipple of reservoir is one and is easy to unheeded parts, because nipple is a finding, and simple in structure.But it plays a significantly greater role in whole refrigeration system, especially its corrosion resistance; In a single day nipple is corroded and gets rusty, and treats that corrosion comes off to get into whole refrigeration system, will cause system jams, makes whole system in paralyzed state.Product receives Effect of Environmental when depositing or transport, the passivation protection film on the nipple surface on the reservoir is destroyed, and has just occurred corrosion inevitably, thereby has directly influenced performance of products.Again because air-conditioning, refrigerator output are huge, and the production cycle is long again, the just inevitable resting period that prolongs, therefore, it is eldest child's difficult problem that the reservoir nipple gets rusty, so that is unfavorable in a large number and the popularization of world market.
Summary of the invention
The present invention is directed to the deficiency of above-mentioned prior art existence and a kind of better anti-corrosion treatment process of nipple rust-proof effect for reservoir is provided.For this reason, the present invention adopts following technical scheme:
A kind of anti-corrosion treatment process to the reservoir nipple is characterized in that, this anti-corrosion treatment process may further comprise the steps:
The first step is coated in antirust solution on the nipple for the first time;
In second step, the nipple of reservoir is carried out phosphatization handle;
In the 3rd step, carry out plastic-blasting and handle;
In the 4th step, carry out baking processing;
In the 5th step, for the second time antirust fluid is coated on the nipple;
The 6th step, left standstill 24 hours, obtain finished product.
As to technique scheme further replenish and perfect, the present invention also comprises following supplementary technology scheme:
Described phosphatization is handled available spray mode and is handled, and the time accomplished in 0.5～3 minute;
Described phosphatization is handled the also available phosphorus mode of soaking and is handled, and the time accomplished in 1～5 minute;
It can be the zinc-iron based phosphatization liquid that said phosphatization is handled used phosphatization liquid;
It can also be the without phosphorus Chrome-free agent of nanometer that said phosphatization is handled used phosphatization liquid;
Described spray treatment is to spray with black powder, evenly distributes, do not have foaming, bright and clean up to the product surface coating;
The used black powder of said spray treatment can be a black plastic-blasting powder;
Temperature during said baking processing is controlled within 200～220 ℃, and the time was controlled within 20～40 minutes.
Compare with the anti-corrosion treatment process of the nipple of existing reservoir, use the present invention can reach following beneficial effect:
Use treatment process of the present invention, the product of gained long deposit or haulage time in be not easy to get rusty.After product was handled through phosphatization, product surface had formed layer protecting film, and this diaphragm can prevent that to a certain extent metal is corroded; On nipple, apply after the antirust solution; Spray again, plastic-blasting handles, and then advances the baking oven baking, after toasting; The antirust solution that is coated in the nipple surface has played further rust inhibition; In bake process, there is part content to infiltrate the nipple metal surface, improves the adhesion of antirust solution and metal, and make diaphragm firmer; The antirust processing second time is carried out on the new designs of threaded joints surface again, makes the metal surface corrosion resistance play duplicate protection.
