Note: Most of our products are shipped quickly. Some items are not in stock and are made to order, which requires factory scheduling and may cause a shipping delay. However, for the vast majority of products, the delivery time is much shorter than expected, and most of customers who place orders will usually receive their goods ahead of the scheduled timeframe.There are two main uses of imaging agents: 1. It is used for metal crack flaw detection Purpose: Mainly used to detect gaps in metal welds.（The effect is very good) Solvent type, washable, adopts Sino-Japanese cooperation formula technology, high sensitivity, low fluorine, chlorine, and sulfur content, and no irritating smell.

The developer used for three-dimensional scanning can be used to spray the surface of the tested object during three-dimensional scanning, so that the surface of the tested object presents a good diffuse reflection, effectively improving the poor quality of scanning data and serious reflection of the tested object due to various colors. Defects such as serious reflection make it easier to scan the tested objects such as black, reflective, and transparent surfaces, and obtain high-quality point cloud data.

There are two main uses of imaging agents:
1. Used for metal gap flaw detection
Purpose:
It is mainly used to detect gaps in metal welds.（The effect is very good) Solvent type, washable, adopts Sino-Japanese cooperation formula technology, high sensitivity, low fluorine, chlorine, and sulfur content, and no irritating smell. Packaging:500mlspray tank
1Set (penetrant1Canisters, imaging agent2Canisters, cleaning agents3cans)
Operation steps:
1.Pre-cleaning: Use a cleaning agent to completely clean the dirt (oxide scale, rust, grease, etc.) on the surface of the inspected workpiece;
2.Penetration: Place5-10After the surface of the workpiece and test block is dried in minutes, apply the penetrant, and the nozzle should be away from the surface of the workpiece and test block.20-30mm,The penetration time should be based on the instructions for use, generally5-15Minutes, during this period, keep the flaw detection surface fully wetted by the penetrant.；
3.Cleaning: Use cleaning agent or water (water pressure ≤1.5kg/cm2）Clean the penetrant on the surface of the workpiece
4.Imaging: After fully shaking the imaging agent, keep a distance from the inspected workpiece300mmSpray evenly on the surface, and after spraying the developer, the defects can be observed for a while.
5.After inspection, use cleaning agent or water to scrub to remove the developer;
6.Handle and store the workpiece according to process requirements.
2. Used for three-dimensional scanning
The developer can be used to spray the surface of the tested object during three-dimensional scanning, so that the surface of the tested object presents a good diffuse reflection, effectively improving the defects of the tested object such as poor scanning data quality and serious reflection caused by various colors, and making the surface Black, reflective, and transparent objects under test are easier to scan and high-quality point cloud data are obtained. The developer has uniform spraying, fine particles, and can be washed with clean water without affecting the scanning accuracy.

Notes:
1) Before penetration flaw detection, surface cleaning and pre-cleaning must be carried out to remove all contamination on the surface of the parts being inspected. DPT-5Colored penetrant inspection agents should be usedDPT-5Cleaning agent removed.
2) The penetration application method should be based on the size, shape, quantity and inspection parts of the parts, and the methods such as spraying, brushing, pouring and dipping should be selected.
DPT-5Dyed penetrant inspection penetration temperature is15～50℃Within the scope, the penetration time is generally divided into5～10minutes; when the penetration temperature decreases to3～15℃The penetration time should be appropriately increased according to the temperature.
3) DPT-5Dyeing penetrant flaw detection is generally wiped with washi dipped in cleaning agent; reciprocating wiping is not allowed, and the inspected article is not allowed to be immersed in cleaning agent or excessive use of cleaning agent;
4)Drying methods include drying with a clean cloth, drying with compressed air, drying with hot air, and drying with a hot air circulation drying device. inZB.J04005-87It stipulates that the drying temperature of the surface of the inspected object should be controlled to no greater than52℃Within the scope.
5) The process of imaging is to use a developer to absorb the permeate from the defect to the surface of the part to produce a clear and visible image of the defect. The imaging time should not be too long and the imaging agent should not be too thick, otherwise the defect display will become blurred.DPT-5The development time of dye penetrant is10～30minutes, developer thickness is0.05～0.07millimeters.
6)DPT-5The traces observed after development of the dye penetrant shall be observed after application of the developer.7～30Conduct it within minutes. If the size of the displayed trace does not change, the above time may be exceeded.
To ensure inspection of subtle defects, the illumination on the inspected parts is at least350Lux.
