Recently, some owners brought a phone call saying that the floor they laid in the summer had cracked a clear gap, and it was not known what caused this. In this regard, the relevant flooring industry explained that: summer room temperature is high, when the pavement floor into the fall and winter season, the physical factors affected by thermal expansion and contraction, easily deformed, and even more obvious cracks. In winter, paving the floor, in the summer there will be the phenomenon of swelling from the drum. Therefore, under normal circumstances, it is best to choose the pavement in the spring and autumn seasons.

If you must choose to work in summer, you must avoid the sun exposure of the floor, to ensure that the room temperature is less than 30 °C; the construction temperature in winter should not be lower than 16 °C. As a city in the south, Chengdu has better flooring conditions than the northern cities. It mainly adopts methods such as ventilation and dehumidification.
The concrete method of paving is: Adjust the floor direction, from the door to the room, the maximum span of the floor is 6 meters by 8 meters. If you exceed this limit, you must leave a contraction joint and use the buckle; the wall root, the door bead interface Reserve expansion joints to be greater than 8 mm; splicing requirements of continuous, uniform, residual glue to be cleaned in time; baseboard must reach 12 mm thick, otherwise it is difficult to cover up the contraction joint; aluminum alloy layer thickness should be guaranteed in more than 2 mm, Too thin and easy to warp and deform. In addition, after the check-in, the floor is best maintained once a month, not only to extend the floor life, but also to prevent the moisture in the air from infiltrating the substrate, resulting in deformation of the floor.
At the same time, here are some minor details that need to be kept in mind for some autumn floor installations:
In the fall, the weather is getting colder and the air is getting drier. When installing the floor, pay attention to read the manufacturer's installation requirements. First, sprinkle water on the ground within ten days before floor installation. Second, after the cement mortar flattened the ground, install the floor for 30 days after ventilation. This is to ensure that the floor humidity meets the requirements for installing the floor. At the same time, the moisture content of the floor will decrease as the moisture content in the air decreases.
In the process of reducing the moisture content of the floor, the floor will shrink naturally due to the loss of moisture of the wood fiber, so the physical phenomenon of the wet expansion and contraction of the floor is unavoidable. If the moisture content is too low, it will directly cause cracks in the floor. Humidifiers, slightly moist mops, etc. can be used to humidify the interior to reduce the loss rate of the floor moisture content.
In addition, the weather in the north has more wind and sand in the autumn, and the floor needs frequent dust removal. Usually, the dust can be removed with a broom or a vacuum cleaner. The place where you often step on is even more diligent in vacuuming. Pay special attention to the hallway and the walkway leading to the outside. To prevent dust from entering the house, place dust-proof pads in the entry area.
There are even some businesses that vigorously promote “free glueâ€, saying that the floor glue used during installation contains formaldehyde and is not environmentally friendly. In fact, the main purpose of glue is to prevent moisture. Consumers often use wet mops or rags to clean the floor at ordinary times. Wipe the floor, the board and the board between the joints easily into the water or moisture, long-term moisture entry will inevitably affect the life of the floor.

This catalog will include those LED that had wavelength from 1400nm to 1500nm, which is one of IR LED range in far red infrared LED. 1400nm and 1450nm IR LED can be package with different size of LED type, with surface mount device type or through-hole type. And different type will also help these IR LED to emit different radiation. The former package methode will allow the IR LED to get a wider radiation area, while the latter will allow the IR LED to get a longer radiation distance.
