　　wet-press pulp tray

　　1. Process

　　¢Dry pressing process:

　　The dry pressing process of molded pulp requires dehydration of the pulp blank, and then pressure shaping or non-shaping under the dry conditions of the pulp molding blank. This process is relatively simple and low-cost, but it requires additional dehydration steps. Generally, the blank dehydration methods include natural drying, sun room drying, drying tunnel drying, hanging basket production line drying and combined drying.

　　¢Wet pressing process:

　　The pulp blanks in the wet pressing process of pulp molding contain high moisture and do not require additional dehydration steps. They need to be placed in the mold, and in the mold, under appropriate pressure and temperature conditions, they are dehydrated and formed into the desired shape. The surface accuracy and density of wet pressed products are relatively good.

　　pulp packaging manufacturer

　　2. Product characteristics

　　¢Dry pressed products:

　　Pulp molded dry pressed products usually have relatively low density, good buffering capacity, and certain compressive strength. Due to the dehydration treatment, they have a low water content and are easy to maintain the elasticity of the fiber itself during shaping. This makes dry pressed products show strong buffering performance in application scenarios that need to withstand greater pressure or impact.

　　¢Wet pressed products:

　　In contrast, molded pulp products manufactured by wet pressing process usually have higher density and smooth surface characteristics. Due to the high water content, they are easier to form complex shapes and textures, because the water is removed during the shaping (setting) process, the fiber density is easy to compact, and the surface quality is better. Wet pressed products are more common in some application scenarios that focus on appearance and tactile experience.

　　molded pulp manufacturer

　　3. Application fields

　　¢Dry pressed products:

　　Pulp molded products manufactured by dry pressing process are often used in the packaging field, such as making sturdy paper boxes, protective lining materials, etc. At the same time, its low density and compressive strength also make it suitable for application scenarios that require higher buffering capacity.

　　¢ Wet-pressed products:

　　Pulp molded products made by wet-pressing are usually used in home decoration, tableware, fine packaging, daily household products, and cultural and creative industries, artworks and other fields. It is light and has a variety of shapes and textures, suitable for creating personalized and elegant products.

　　Today, Sunlit-tech will introduce the working principle of the GSM alarm system. First, let’s introduce the concept of the security gsm alarm system. The security gsm alarm system uses the global GSM short message data transmission mode and voice function platform to complete intelligent data remote transmission and control alarm. The system integrates smart home functions such as home, store, office security, electrical appliance control, and private car remote monitoring. Due to the wide coverage of the GSM global wireless mobile communication network signal, it truly realizes low-cost and high-quality ultra-long-distance convenience and flexible intelligent wireless control and alarm, solving the limitations of fixed-line or wired broadband network wired alarm. The GSM global wireless mobile communication network has been popularized throughout the world and is widely used in security devices, data monitoring and remote monitoring systems in single-family, community property, electricity, transportation, petroleum, coal, railways, municipal administration, public security and other departments and industries.Even if there are obstacles to moving forward, wired PIR motion sensor We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. https://www.sunlit-tech.com

　　The anti-theft alarm system usually consists of three parts: detector (also known as alarm), transmission channel and alarm controller. The GSM alarm detector is composed of sensors and signal processing. It is used to detect the intrusion behavior of intruders. It is a device composed of electronic and mechanical components. It is the key to the anti-theft alarm system, and the sensor is the core component of the alarm detector. Using sensors based on different principles, alarm detection devices of different types, different uses and different detection purposes can be formed.

　　1. Alarm detectors can be mainly divided into infrared alarm detectors, microwave alarm detectors, passive infrared/microwave alarm detectors, glass break alarm detectors, vibration alarm detectors, ultrasonic alarm detectors, laser alarm detectors, magnetic switch alarm detectors, switch alarm detectors, video motion detection alarms, sound detectors and many other types according to their working principles.

　　2. Alarm detectors can be divided into active alarm detectors and passive alarm detectors according to their working modes.

　　3. Alarm detectors can be divided into point-controlled alarm detectors, line-controlled alarm detectors, surface-controlled alarm detectors and space-prevention alarm detectors according to their detection range.

　　In practical applications, choosing the right type of gsm alarm system is crucial to meeting different security needs. As a sensing device, the gsm alarm system is responsible for monitoring the activities of intruders and various abnormal situations. Whether in smart buildings or ordinary buildings, the needs for security prevention are extensive and diverse. These places have different security needs and goals according to actual conditions, so multiple types of alarm detectors are needed to meet these requirements.
