Electronic Industry Standard of the People's Republic of China
Integrity requirements and inspection and evaluation methods for general electroplating tanks 1 Subject content and applicable scope
This standard specifies the integrity requirements and inspection and evaluation methods for general electroplating tanks. SJ/T 31052—94
This standard is applicable to various types of electroplating tanks, cleaning tanks, degreasing tanks, etching tanks, etc. Other types of auxiliary tanks can also refer to this standard.
2 Integrity requirements
2.1 Main parameters and performance indicators
The volume, temperature, and cooling water flow of general tank equipment should comply with the values ​​specified by the manufacturer. 2.2 Tank healthbZxz.net
2.2.1 The tank body is in good condition, and the joints are not desoldered, leaking, or severely deformed. 2.2.2 For lead-lined plating tanks, the leak detection device is complete. 2.2.3 The heating and cooling devices operate normally. 2.3 Transmission device
2.3.1 The transmission device operates smoothly and has good performance. 2.3.2 The mechanical stirring mechanism is sensitive and reliable. 2.4 Temperature control device
2.4.1 The temperature bag sheath is not damaged or corroded.
2.4.2 The temperature indicator data is correct.
2.5 Electrical system
2.5.1 The rectifier device operates normally, the various instruments indicate correctly, the error is within the tolerance range, and the instruments are within the valid calibration period. 2.5.2 The electric control device is complete, the lines are arranged neatly, the performance is good, and the operation is reliable. 2.5.3 The surface of the conductive rod should be smooth and free of corrosion. 2.5.4 When using metal support rollers, they must be insulated from the steel tank shell, and the insulation resistance must not be less than 1000/V. 2.6 Lubrication device
The lubrication device is complete, the oil level is eye-catching, the oil window is bright, and the injected lubricating oil or grease is clean and in place. 2.7 Safety protection
2. 7. 1 The acid and alkali bond tanks should be equipped with exhaust hoods. 2.7.2 The sewage discharge should comply with the provisions of Article 1.1.3 of GB8978-88 Comprehensive Sewage Discharge Standard. The sewage discharged into the waters of this area shall comply with the secondary standard.
Approved by the Ministry of Electronics Industry of the People's Republic of China on April 15, 1994 and implemented on June 1, 1994
2.8 Maintenance and care
The inside and outside of the plating tank are clean, and there is no dirty liquid on the ground.
3 Inspection and evaluation methods
3.1 Inspection method
SJ/T-31052-94
In this standard, 2.5.4 is tested by a multimeter, 2.7.2 is tested by the environmental protection department, and the rest are tested by subjective methods. 3.2 Assessment method
3.2.1 In this standard, 2.1, 2.2.1, and 2.5.1 are the main items, and the rest are minor items. If one of the two main items does not meet the requirements, it is an incomplete equipment. If two of the minor items do not meet the requirements, it is also an incomplete 3.2. 2
equipment.
