Abstract
The invention relates to a method for processing rusty chains. The method for processing the rusty chains includes the following steps that the common rusty steel chains in a workshop are placed in a citric acid solution of which the concentration is 25wt%, and the chains are soaked in the citric acid solution for 2-4h; ultrasonic processing is conducted on the soak solution for 2-4h, and the power of ultrasonic processing is 1200-1400w; the chains are further soaked in an oxalic acid solution of which the concentration is 20wt% for 1-3h; after being soaked, the chains are grinded by abrasive paper until rust on the surfaces of the chains is removed; the chains are uniformly sprayed by mineral oil, and then the antirust chains are prepared. The prepared chains have the good antirust function.
Description
Technical field
The present invention relates to a kind for the treatment of process of chain, particularly relate to a kind for the treatment of process of the chain that gets rusty.
Background technology
Common steel chain, due to preparation technology and raw-material restriction, therefore there will be the situation of getting rusty after using certain hour or standing atrocious weather, and treatment process has a variety of, and Physical, chemical method, mechanical process etc. are arranged.But some method has produced poor impact to the performance of chain, therefore have certain disadvantages.Find a kind of method that can remove rust staining, on not impact of chain itself, can there are good market outlook simultaneously.
Summary of the invention
The technical problem solved: the problem that conventional steel chain gets rusty.
Technical scheme: the invention discloses a kind for the treatment of process of the chain that gets rusty, treatment step is as follows:
(1) the common steel chain got rusty between picking up the car, add the citric acid solution that concentration is 25wt%, and chain is crossed in submergence, and soak time is 2～4h;
(2) soak solution is carried out to supersound process, supersound process power is 1200～1400w, and the time is 2～4h;
(3) with the oxalic acid solution of 20wt%, soaked, soak time is 1～3h again;
(4) after soak finishing, with sand paper, chain is polished, till polishing and removing to chain surface rusty stain;
(5) chain is sprayed evenly with mineral oil, prepare antirust chain.
Beneficial effect: the conventional steel chain that treatment process of the present invention obtains has had good rust-proof effect, the chain of crossing through disposal methods of the present invention is placed after 3 months in water at normal temperatures, the situation of not getting rusty produces, can be for preventing getting rusty of conventional chain.
Embodiment
Embodiment 1
