Smart Film Roll can be electronically controlled and adjusted in two states of transparency and atomization.
Dimming glass is being put to creative use in hotels and other leisure areas to create unique experiences, including home decoration with smart glass walls, internal partitions that can function as projection screens, and stylish windows that don`t require blinds or curtains. As smart glass is a special laminated glass, it has all the good functions of laminated glass, mainly safety.
Once the size of the Smart Film Roll is determined, it basically cannot be changed, so it is very important to measure the size of the glass. Only in this way can the smart film match the glass. Basically, the Custom Switchable Film is attached to a piece of glass, but sometimes the glass is larger than the smart film. In this case, splicing and pasting requires multiple dimming films. If it is made of glass and glass, when cutting the dimming film, be sure to subtract the size of the glass glue at the joint and make a mark.

Precautions for Use Gas leak alarms Once the fixed installation is in place, the location of the gas leak alarm is not easily changed. The following points should be taken into consideration when using the gas leak alarm.
(1) Find out which possible leakage points of the devices to be monitored, analyze their leakage pressure, direction and other factors, and draw the distribution map of the probes, and classify them into three grades I, II and III according to the severity of the leakage.
(2) Determine the direction of leakage of toxic gas when there is a large amount of leakage, based on specific factors such as the airflow direction and direction of the location.
(3) According to the density of leaked gas (greater than or less than air), combined with the trend of air flow, integrate the three-dimensional flow chart of leakage and make an initial set-point scheme at the downstream position of the flow.
(4) The leakage status of the leaking point was studied as microleakage or jetting. If it is a microleakage, set the position of the point to be near the leak. If it is a spray-like leak, keep it slightly away from the leak. Combine these conditions and draw up a final plan. In this way, the number and type of purchases needed can be estimated.
(5) For locations where there is a large leakage of toxic gases, a detection point should be set at a distance of 10-20 m per relevant regulations. For unattended, small, non-continuous pumping stations, attention should be paid to the possibility of toxic gas leakage, and a detector should generally be installed at the downtake.
(6) For locations with hydrogen leaks, the detector should be installed on the plane above the leak.
(7) For media with a gas density greater than air, the detector should be installed on the lower surface below the leak point and pay attention to the surrounding environment. For places where toxic gases can easily accumulate, special attention should be paid to the setting of safety monitoring points.
(8) For open toxic gas diffusion and escape environments, if there is a lack of good ventilation conditions, it is easy to make the toxic gas content in the air close to or reach the lower explosion concentration in a certain area. These are all non-negligible safety monitoring points. . According to the results of field accident analysis, more than half of them were caused by incorrect installation and calibration. Therefore, it is necessary to introduce the correct installation and calibration precautions to reduce the failure.
Analysis of the use of gas leak alarm precautions
The gas leak alarm consists of detectors and alarm control mainframes. It is widely used in the petrochemical industry where there are toxic gases such as petroleum, gas, chemicals, and oil depots. It is used to detect leaks in indoor and outdoor hazardous locations and is to ensure production and personal safety. Important instrument. When there is toxic gas in the tested site, the detector converts the gas signal into a voltage signal or a current signal and transmits it to the alarm meter. The instrument displays the percentage concentration of the lower explosive limit of the combustible gas. When the concentration of flammable gas exceeds the alarm set value, an audible and visual alarm signal is generated. The on-duty personnel take safety measures in time to avoid the occurrence of explosive explosion.
