First, the film thickness check:
Needle puncture method should be used to puncture three points per 100 square meters, measure the height with a ruler, take the average value, and the film thickness should be greater than 2 mm. Use a marker to mark the puncture for repair.
Second, the elongation of elongation check:
In the waterproof construction, the supervisors can go to the construction site to apply the mixed materials to the flat glass plate (the glass plate should be waxed first), the film thickness is 1.2-1.5 mm, and after 7 days, Immerse in 1% alkaline water for 7 days, then bake in a 50 ° C soil 2 ° C oven for 24 hours to do a dumbbell-type tensile test, requiring an elongation retention of 80% (200% without treatment). If the standard is not reached, it indicates that the proportion of emulsion blending is insufficient during the construction. (This method is limited to ordinary two-component coatings)
Third, water resistance check:
The paint is applied to the cement block several times, and the film thickness is 1.2-1.5 mm. It is placed for 7 days, and then immersed in 1% alkali water for 7 days without delamination.
Fourth, the watertight inspection:
Under the condition, the instrument is tested. The method is to proportionate the paint, apply it to the glass plate several times (the glass plate is waxed first), the thickness is 1.5 mm, let it sit for 7 days, then put it in the oven. The inside was baked at 50 ° C ± 2 ° C for 24 hours, and after taking out, it was allowed to stand for 3 hours, and the impermeability test was carried out, and the water impermeability was 0.3 MPa. No leakage for 30 minutes was acceptable.
If the conditions are not available, the waterproof effect can be checked by visual inspection by applying the coating to the non-woven fabric 4-6 times, and after drying (about 24 h), the film thickness is 1.2-1.5 mm, which is made into a slow box shape. Hang out, but do not leave a dead angle, then add 1% alkaline water to the inside of the box, 24h no leakage is qualified.
Five, low temperature compliance check:
Wax on the glass plate, the paint mixed on the construction site is applied to the glass plate several times, the film thickness is 1.2-1.5 mm, and after drying, it is removed from the glass plate and placed indoors (25 °C ± 2 °C) ) 7 days, then cut the strip 120-150 mm long and 20 mm wide, adjust the temperature of the refrigerator to -25 ° C, put the test piece in the refrigerator for 30 minutes, and wrap it with the diameter of 10 mm round bar. No cracks are acceptable. If there is a crack, the emulsion is not soft enough.
There are three types of Dip switch led batten lights, Change CCT Light, Change Power Light, and Change CCT and Power light.
In other words, this batten light can change the color temperature and power. It is mainly possible to change the color temperature and power by turning the DIP controller inside the lamp body. Moreover, you only need to press the button on the side of the light to open the light body, which is very easy to operate.
The function of changing color temperature and power is very suitable for stock. Before shipping, you can set the color temperature and power that your customers want.
The adjustable range of color temperature is: 3000k/4000k/5000k, 4000k/5000k/6000k.
The power adjustment range is: 5 /10 /15 /20, 5 /15 /25 /30, 10 /20 /30 /40, 10 /25 /40 /50, 10 /25 /40 /50, 20 /30 / 50/60.
This batten light is suitable for warehouses, shops, corridors, offices, factories, and other indoor places.
