Abstract
The invention relates to the field of electroplating technologies, in particular to an antirust sealing technology of a workpiece. The antirust sealing technology comprises the steps that 1, the surface of the workpiece is pretreated, that is the workpiece is subjected to water washing in a water environment with a pH value of 8-12, and then subjected to the water washing for the second time in the same environment to form a standby workpiece; 2, the surface of the workpiece is subjected to sealing treatment, that is the standby workpiece is put in tank liquor with an antirust sealing agent and soaked for 10-20min at a normal temperature; and 3, the standby workpiece treated by the antirust sealing agent is subjected to the water washing and then pure water washing. With the adoption of the antirust sealing technology, an antirust function is better; the antirust time is longer; the working efficiency is high; and the production cost is lowered.
Description
Technical field
The present invention relates to the electroplating technology field, specifically the antirust closing process of a kind of workpiece.
Background technology
Because having a lot of SECC, SGCC material not to do the surface, present company processes, section has problem of rustiness, need touch-up paint at every turn or be coated with the silver lacquer, both wasted man-hour, the dead angle easily occurring again can not guaranteed quality, if in addition by galvanized sheet and heat zinc coating plate PROCESS FOR TREATMENT, the surface of the work corrosion-resistant, effect is undesirable.All can there be certain requirement in businessman at aspects such as corrosion resistance, brightness, pliabilitys when selecting plating piece, and in these areas, traditional process can not satisfy present requirement to product, for this reason the antirust new technology of special this section of test.
Summary of the invention
For the problems referred to above, the invention provides antirust function better, the antirust time is more of a specified duration, the antirust closing process of a kind of workpiece of high efficiency.
The present invention is achieved by the following technical solutions: the antirust closing process of a kind of workpiece, comprise: step 1, the surface of the work pre-treatment, at normal temperatures namely, in pH value is 8～12 water environment, wash, under equivalent environment, carry out again afterwards the secondary washing and obtain workpiece for subsequent use; Step 2, the surface of the work sealing is processed, and namely under the normal temperature, workpiece for subsequent use is put into the clean stain of the tank liquor 10～20min that adds antirust sealer; Step 3 will be washed through the workpiece for subsequent use that antirust sealer is processed, and then be carried out pure water and wash.
As preferably, step 2, the ratio of described tank liquor and antirust sealer are that every 1000L tank liquor adds antirust sealer 40～60kg, and full basicity is controlled at 22～28pt.
As preferably, step 3, the pH value of described washing is 8～12, temperature is 40～50 ℃.
As preferably, step 3, the pH value that described pure water is washed is 7～9.
The present invention has taked above-mentioned corrective measure to carry out, and workpiece is directly steeped antirust sealer only, does not need artificial coating, and its beneficial effect is remarkable:
1. adopt antirust sealer protection section rust-proof effect more superior than the surface corrosion-resistant erosion property performance of galvanized sheet and heat zinc coating plate.
2. the effect that adopts antirust sealer protection section rust-proof effect to be coated with the processing such as silver lacquer than artificial section is good, and the antirust time is improved one times nearly than original.
3. adopt antirust sealer to process section higher than manually being coated with silver lacquer efficient, and the artificial antirust processing of section such as aperture, little corner less than the place all can process, to protect than manually being coated with silver-colored lacquer comprehensively.
4. adopt antirust sealer to process section and reduce work hours than manual work, greatly reduce production costs, through estimation, approximately save time 40%.And the product fine rate is also high than manual work.
5. nonhazardous, convenient and swift, guaranteed preferably product quality.
The specific embodiment
The present invention is further illustrated below in conjunction with embodiment: antirust sealer is purchased Shengzhou spring triumphant new material Co., Ltd, and the trade mark is CC-202.
Surface of the work is not processed through antirust sealer among this embodiment, and the cutting workpiece face is processed through antirust sealer, and contrast property is strong.
Embodiment 1, the antirust closing process of a kind of workpiece, and step 1 at normal temperatures, with work piece cut, is formed with section.Be to wash in 8 the environment through pH value with this workpiece, be placed on again afterwards and carry out the secondary washing in the equivalent environment, remove the impurity dust on the workpiece, obtain workpiece for subsequent use; Step 2 at normal temperatures, is that every 1000L tank liquor adds antirust sealer 40 kg configuration tank liquor according to the ratio of tank liquor and antirust sealer, and full basicity is controlled at 22pt, and is for subsequent use.The section of workpiece for subsequent use is contacted this tank liquor, and only steep 10min; Step 3, will put into temperature through the workpiece for subsequent use that antirust sealer is processed is 40 ℃, pH value is to wash in 8 the environment, and then to put into pH value be that 7 environment carries out pure water and washes.
Result of the test is observed:
The first situation: the workpiece that will finish processing is placed under the normal temperature (the daily storage condition of simulation) to be deposited, and deposits and observes the section non-corroding in four months.Proved that corrosion resistance is strong.
The second situation: the workpiece that will finish processing is placed in the neutral salt spray test case to be deposited, and through 42 hours neutral salt spray tests, processes section through antirust sealer better than surface of the work corrosion resistance.Proved through after the processing of antirust sealer, more difficult antirust.
Embodiment 2, the antirust closing process of a kind of workpiece, and step 1 at normal temperatures, with work piece cut, is formed with section.Be to wash in 12 the environment through pH value with this workpiece, be placed on again afterwards and carry out the secondary washing in the equivalent environment, remove the impurity dust on the workpiece, obtain workpiece for subsequent use; Step 2 at normal temperatures, is that every 1000L tank liquor adds antirust sealer 60 kg configuration tank liquor according to the ratio of tank liquor and antirust sealer, and full basicity is controlled at 28pt, and is for subsequent use.The section of workpiece for subsequent use is contacted this tank liquor, and only steep 20min; Step 3, will put into temperature through the workpiece for subsequent use that antirust sealer is processed is 50 ℃, pH value is to wash in 12 the environment, and then to put into pH value be that 9 environment carries out pure water and washes.
Embodiment 3, the antirust closing process of a kind of workpiece, and step 1 at normal temperatures, with work piece cut, is formed with section.Be to wash in 10 the environment through pH value with this workpiece, be placed on again afterwards and carry out the secondary washing in the equivalent environment, remove the impurity dust on the workpiece, obtain workpiece for subsequent use; Step 2 at normal temperatures, is that every 1000L tank liquor adds antirust sealer 50 kg configuration tank liquor according to the ratio of tank liquor and antirust sealer, and full basicity is controlled at 24pt, and is for subsequent use.The section of workpiece for subsequent use is contacted this tank liquor, and only steep 15min; Step 3, will put into temperature through the workpiece for subsequent use that antirust sealer is processed is 45 ℃, pH value is to wash in 10 the environment, and then to put into pH value be that 8 environment carries out pure water and washes.
