Shanghai Shifu Wet Film Cabinet Machine (New Heavyweight Product)

Working principle When the humidifier is working, the tap water that has been filtered multiple times directly enters the water tank. The circulating water pump continuously delivers the water directly to the water distribution system at the top of the humidifier, evenly spraying the water on the high-efficiency evaporation material. The water seeps down from the top of the high-efficiency evaporation material and is absorbed by the high-efficiency evaporation material to form a uniform water film. The air flows rapidly through the axial flow fan. When the dry air is sucked into the humidifier by the fan, some of the water comes into contact with the dry air, absorbs heat, and vaporizes, making the air moist (increasing humidity). The other part of the water that has not evaporated flows back to the water tank and is repeatedly used through the circulating water pump. When the water level drops to a lower level, the float valve automatically opens to replenish water to the water tank, and when the water is full, the float valve automatically closes.

Characteristics of Wet Film Humidifiers

1. Humidification is clean, without the "white powder" pollution of traditional humidifiers. Water does not need to be treated, as long as the moisture is evaporated, it can be cleaned and humidified.
2. ＊ Power saving, which is 2% of the power consumption of electrode (electric heating) humidifier, no nozzle, no spray, no water dripping, and no need for compressed air.
3. Humidification is carried out naturally and stably according to indoor air conditions, without being limited by the on or off of the air conditioning system and the operation mode of the air conditioning unit.
4. The circulating water volume of the water pump is greater than the humidification capacity, and the excess water is used to clean the evaporating material, which does not produce scale.
5. Evaporative materials have a purifying effect on the air, which can remove dust and harmful gases dissolved in water from indoor air.
When the indoor sensible heat load is high, use dry and hot air for evaporation and vaporization; Has good cooling effect.
7. Install the model separately, with a built-in fan, and select the model and quantity according to the indoor humidification load.
8. Equipped with universal casters, easy to move, and adjustable airflow direction.
9. The evaporation material is an imported high specific surface area anti-counterfeit wet film, which is resistant to mold, bacteria, and has a lifespan of 8-10 years.
10. The higher the air temperature and the drier it is, the more it can improve the humidification capacity, and the humidification saturation efficiency can reach over 90%.

Technical parameters:

Humidity self-control:When the humidity reaches the set value, the humidifier automatically stops. When the humidity drops, it automatically turns on for humidification to maintain the required room humidity.

3When the machine runs out of water, it automatically stops working and the water pump does not run. It can automatically drain and ensure the cleanliness of the water tank.

Key points for humidification in electronic factory buildings and computer rooms

Wet film humidification belongs to evaporative isentropic humidification, and the humidification process occurs on the surface of the wet film (inside the cabinet), thus eliminating the risk of water falling and condensation, and ensuring reliable installation.

Electronic production workshops, especially surface mount technology (SMT) workshops or communication rooms, usually have extremely high internal heat, and air conditioning supplies air at low temperatures throughout the year. At this time, it is obviously impossible to meet the humidification requirements by cooperating with air conditioning supply and humidification. Cabinet style wet film humidifiers installed in the workshop directly process the dry and hot air in the workshop, increasing air humidity while also reducing workshop temperature, and achieving energy-saving humidification effects.

For the majority of electronic companies, due to the low indoor air moisture content in winter, appropriate humidification is required. For users with central air conditioning (including units with added sections), it is recommended to use membrane circulating water humidifiers or high-pressure micro mist with water blocking plates for humidification, which is more energy-efficient and environmentally friendly.

Automatic humidity control (standard configuration) Place the humidity sensor controller in a location where the humidifier cannot directly blow and is easy to observe, connect the wall power supply, and connect the output terminal to the humidifier. This way, when the humidity reaches the set value, the humidifier will automatically stop humidifying. When the humidity drops, it automatically turns on for humidification to maintain the required room humidity. Large font high brightness digital display screen, long-life resistive humidity sensor controller. Control accuracy ± 5%.

Filter (standard configuration) 10 inch 5 μ cup precision filter, specially designed without cracking, can filter out rust in water Solid particles such as sand, hemp rope, raw material tape, colloids, etc. We also offer alternative water tanks with stainless steel or hard plastic casings.

Fully automatic water softener, pure water purifier (optional) Use the fully automatic water softener provided by Shifu Company to delay the formation of wet film fouling on the evaporation material (extend the replacement time, usually every 8-15 years). The control head of the fully automatic water softener is a product of FLECK, a US company. The device has a high degree of automation and is controlled by a program to achieve automatic operation. The regeneration process is fully automated, and users only need to regularly add regeneration agents (industrial salt) to achieve continuous water supply under fully automatic conditions. Selection of Humidifiers for Electronic Workshops At present, domestic electronics companies have increasingly strict requirements for workshop quality and static electricity. In order to ensure the factory quality of products, it is necessary to strictly control the temperature and humidity in the production workshop, especially the humidity. If it is too dry, static electricity is easily generated in the factory, causing damage to CMOS integrated circuits,

Explanation of Static Electricity Knowledge

1. Static electricity is a static charge. Any two objects of different materials that come into contact and then separate will generate static electricity

The main ways of static electricity generation are friction, contact and separation, and induction.

In daily life, common and obvious static electricity includes lightning; The electric shock sensation when walking on the floor mat and touching the handle in winter; The crackling sound produced when wearing clothes in winter. These have no impact on our human body, but they have a significant impact on electronic components and circuit boards.

Examples of the hazards of static electricity in the electronics industry

AWafer fabrication

1. Electrostatic adsorption of fine dust particles, contaminating chips

2. The radio frequency generated by electrostatic discharge interferes with production and causes mechanical parts to stop without reason

Bintegrated circuit

1. Electrostatic discharge breaks through the oxide layer, causing a short circuit

2. The discharge current of electrostatic discharge melts the wire part of the metal layer, causing an open circuit

3. The high temperature generated by electrostatic discharge changes the properties of semiconductors and causes abnormal operation.

4. Electrostatic discharge causes some minor damage, and when the finished product is working normally, the minor damage will expand, causing the final product to malfunction.

CAssembly of integrated circuits on circuit boards

Static discharge effects may occur during insertion, welding, or maintenance, which can damage components on the board

DManufacturing of LCD panels

1. Electrostatic adsorption of fine dust onto glass, causing pollution

2. Static electricity remains between two pieces of glass, which can affect the display of the LCD panel when discharged

In short, there are two main phenomena of static electricity hazards:

1. Completely lose function
   Devices cannot be operated, which accounts for 10% of components damaged by static electricity.

2. Intermittent loss of function

The device can be operated but its performance is unstable, resulting in an increase in maintenance times. This situation accounts for 9.0% of components damaged by static electricity.

（2）Lack of electrostatic protection may cause

Increasing costs, reducing quality, causing customer dissatisfaction and affecting the company's reputation

Humidity control

The relative humidity of the anti-static work area should not be lower than 40%.

Humidification equipment is allowed to increase environmental humidity without causing harmful effects to the product.
