PUR hot melt adhesives are a type of adhesive that is commonly used in industrial applications. PUR stands for polyurethane reactive, which refers to the chemical composition of the adhesive.
These adhesives are typically applied in a molten state and then solidify as they cool. They offer a number of advantages over other types of adhesives, including:
1. Strong bond: PUR hot melt adhesives create a strong and durable bond between materials. They can bond a wide range of substrates, including wood, plastic, metal, and foam.
2. Fast curing: PUR hot melt adhesives have a relatively fast curing time, allowing for quick assembly and production processes.
3. Heat resistance: Once cured, PUR hot melt adhesives have excellent heat resistance. They can withstand high temperatures without losing their bond strength.
4. Moisture resistance: PUR hot melt adhesives are resistant to moisture and can be used in applications where the adhesive may come into contact with water or other liquids.
5. Flexibility: PUR hot melt adhesives remain flexible even after curing, making them suitable for applications that require some degree of flexibility or movement.
6. Chemical resistance: These adhesives have good resistance to chemicals, making them suitable for applications where exposure to harsh chemicals is expected.
7. Environmentally friendly: PUR hot melt adhesives are considered to be more environmentally friendly compared to other types of adhesives. They do not contain solvents or volatile organic compounds (VOCs), making them safer to use and reducing the impact on air quality.
Overall, PUR hot melt adhesives are versatile and offer a range of benefits that make them suitable for a wide range of applications in industries such as packaging, automotive, construction, and woodworking.

How to set the appropriate multi-function paging microphone microphone distance?
Multi-function paging microphone microphone This kind of close-range pickup can easily produce “beep†or “beep†if it is not handled properly. The solution is to deviate the microphone from the host's mouth direction and change the declination and Sonic people shoot angles, professional teaching microphones, thus controlling the sound pressure of different frequencies of the sound source. For those descriptive programs, the sound is required to be slightly neutral, and the pickup distance is about 5-15 cm. In the recording of the language program, whether the setting of the microphone is appropriate, and finally should be judged by the effect of the hearing.
Multi-function paging microphone use: generally placed in the main control room and sub-control room, can carry out one-way broadcast, two-way intercom and monitor monitoring.
The multi-function paging microphone has various models . When the multi-function paging microphone is broadcasting, intercoming, monitoring and on-demand, the relay is triggered, the indicator light is on, and the relay output is short-circuited. When the pause or stop works, the relay stops working, indicating The light goes out. The multi-function paging microphone is configured with up to 22 buttons, which can be set up by the system, or the IP of other terminals can be entered into the address book, and the terminal can be operated through the address book. Multi-function paging microphones are mainly used in campuses, banks, hospitals and mines where broadcasting, intercom, on-demand and monitoring are required.
