How to distinguish the quality of integrated ceiling
As with other building materials, integrated ceilings are used for decades or even lifetimes. It is crucial to purchase high-quality integrated ceilings. How do we look at the quality of integrated ceilings when buying integrated ceilings? How to distinguish the quality of integrated ceiling? Following Xiaobian learn how to identify the quality of integrated ceiling quality!
1. Integrated ceiling lighting module: The lighting module generally has two forms: round and square. No matter what kind of shape, the main factors that determine the quality of lighting include light source, ballast, mask, circular ring, etc. . The method of discriminating the merits of the lamp ring is to use a hard object (such as a key) to scrape a few light on the surface of the lamp ring. The high quality lamp ring will only have a few traces, and the hand will recover as soon as it is wiped; the poor lamp circle will become black and cannot be restored. The price difference between the pros and cons is very large, so consumers can't just look at the price when they buy, and they can be more sensible than the price on the premise of the same quality.
2, integrated ceiling heating module: heating module is mainly warm and warm air two, the market will have a combination of warm and warm wind. The quality of the lamp is mainly heating bulbs, heating bulbs using infrared radiation principle for heating, high quality heating bulbs with uniform wall thickness, bulb wall without bubbles, cold water will not burst during use, the higher the quality of the brand, before leaving the factory Cold water spray test to ensure safety. At present, the core component of the air-heating integrated ceiling is PTC. Therefore, the PTC's good or bad is the main factor determining the air-warm quality. PTC is a combination of one unit and each unit needs to be energized during the work, so the boundary terminal's The quality is very important. The high-quality terminals are made of pure copper. The copper plating or galvanizing are inferior products. In addition, whether there is a silicone insulating layer between each unit is also an effective method for judging the merits. No insulation layer is definitely Inferior products are known by consumers at the time of purchase.
3, integrated ceiling ventilation module: noise and vibration is the main problem of the ventilation module in daily use, so consumers should focus on whether the ventilation fan has a shock absorption structure or device, if there is no shock absorption After the structure and device are in use, noise and vibration problems are likely to occur; another factor in the quality of the ventilation fan is the cabinet. The high-quality cabinet has good color and elasticity. People who weigh less than 70 kilograms can stand without problems. If you can't afford it, it's very likely that you will use poor quality raw materials.
4. Integrated ceiling buckle plate: Currently, the buckle plate on the market mainly includes four types of coating, roll coating, oxidation and printing plate. The main printing quality that affects their quality is the quality of the used substrate, indicating the environmental protection of the processing process, and the splicing gap. The size and so on. One thing to note is that the thickness is not as thick as possible. The high-quality base material has a large elasticity, high strength, and a crisp sound. It can be felt by shaking it by hand. This is difficult for consumers to judge; environmental protection, The most direct method is to use the nose to smell, take a piece of unbuckled film, you tear a corner, smell it with the nose, there is certainly a pungent odor is not environmentally friendly.

The instruction of digital measuring wheel
Please read this instruction before you use the product
Thanks you for choosing our product. This instrument is a new length measuring instrument, it is easy to use,stable and reliable.
The main features:
You could convert the unit between metric and foot; The data could be stored and extracted; The touch switch of the digital measuring wheel is anti-water; The handle which could adjust the height of the instrument is easy to apply. The wheel wrapped with rubber could help to avoid slipping so that the measuring data is more precise.
1.The main parts (From up to down):
Handle
Data display panel
Battery cover
Handle lock
Measuring wheel
Kickstand
2. Technical data:
A. It could measure up to 99999.9m/ft.
B. Accuracy:+/- 0.3%
C: Minimal display :0.1m
D: Power supply 3V (2xAAA LR003)
E: Suitable temperature for use : -10c°~45c°
3. Button and Operation
CLR: Clearance
SM : Store the data
ON/OFF: Switch
Rm: Extra the data
M/ft: Conversion between metric and foot
Data display panel
Power supply
The stored data
The displayed data
Metric
Foot
1. ON/OFF : Switch.
2. m/ft: it means the conversion between metric and foot. If you select (m), the displayed data is based on metric. If you select (ft) ,the displayed data is based on foot.
3. SM: Store the data. You could save the data that shows on the display panel by pressing this button. It could store 5 records that respectively show on M1, M2,M3, M4, M5.( Refer to Table 1)
Before storing After storing Full of the memory
(Table 1)
4. RM: Extract the stored data from SM. For example, if you have already stored the measuring data 5M as M1, 10M as M2. But now the measuring data is 120.7M, you could press the bottom RM once then the digital display panel will shows the the data of M1. The top right of the display panel shows [R". The data of the digital display panel will return to the present data after two seconds. ( Refer to Table 2). If you press the RM twice, the data of the M2 will show on the display panel, the [R" also is on the top right. The data of the digital display panel will return to the present data again after two seconds.
Present data Press the RM Once After 2 seconds
(Table 2)
Present data Press the RM twice After 2 seconds
(Table 3)
5. CLR: Clearance. Once you press this button, the present data will be deleted.
4.Precautions for use
Please open the handle lock to adjust the suitable height of this instrument at first and then close it before using the instrument. Put away the kickstand and turn on the power. Put the wheel on the road to be measured when the data is 0.0m on the digital display panel. Please press the bottom CLR if you want to delete the present data.
