The clean workbench is to control the cleanliness, temperature and humidity of the atmosphere that the product (such as silicon chips, etc.) is exposed to, so that the product can be produced and manufactured in a good environmental space. The design and construction process of this environmental space can be called a purification project. Turbulent Cleanroom:

The main feature of the turbulent clean room is that the flow cross-section of the air flow between the incoming flow and the outflow (from the air supply outlet to the return air outlet) is varied, and the clean room cross-section is much larger than the air supply outlet cross-section, so it cannot form a uniform airflow in the whole room section or in the whole room working area section. Therefore, the streamlines after the air supply outlet have a large or larger angle with each other, the radius of curvature is very small, and the air flow cannot flow in a single direction in the room, and will collide with each other, and there will be reflux and vortex.

Principle of purification workbench: clean environment is formed by the flow of clean air (inlet filter air) in a specific space according to the set direction. In terms of airflow direction, the existing clean bench can be divided into vertical, inside-to-outside and sideways.

In terms of operation quality and environmental impact, the vertical type is superior. The clean air supplied by the air supply filter plate descends through the operating area at a specific rate, separates in the middle of the operating area, is sucked away by the front air suction hole and the rear suction window, the air inhaled in the front and rear parts of the lower part of the operating area is mixed together, and is pumped into the rear positive pressure zone by the blower, in the upper part of the machine, 30% of the gas is discharged from the top through the exhaust filter plate, and about 70% of the gas re-enters the operation area through the oxygen supply filter plate. In order to replenish the air discharged from the exhaust port, the same volume of air is replenished from the room air through the operating port.

This air does not enter the operating area, but simply forms an air barrier.

There are two main ways of ultraviolet sterilization when ultraviolet sterilization is used: one is direct irradiation sterilization by ultraviolet rays, and the other is ozone sterilization produced by ultraviolet ionized air;

When turning on the ultraviolet rays, do not turn on the air first, and irradiate enough time, and disinfect with alcohol before operation.

Sterilization process:1Turn on the power of the workbench, turn on the machine 40 minutes in advance, turn on the ultraviolet sterilization cluster at the same time, treat the microorganisms accumulated on the surface of the operation area, turn off the sterilization lamp after 30 minutes (the fluorescent lamp will be turned on at this time), and start the fan.

2.Do not store unnecessary items on the clean work surface to keep the clean airflow in the work area undisturbed;

3.After the operation, clean the workbench surface, collect all wastes, turn off the fan and lighting switch, and wipe and disinfect with cleaning and disinfectant;

4.Finally, turn on the ultraviolet lamp on the ultra-clean workbench, and after 30 minutes of irradiation and disinfection, turn off the ultraviolet lamp and cut off the power supply. It is necessary to pay attention to frequently wipe the surface of the ultraviolet germicidal lamp with gauze dipped in alcohol to keep the surface clean, otherwise the germicidal ability will be affected.

The clean workbench is sterilized with a UV lamp, and if the humidity is large enough, ozone can also be generated, which is generally enough for half an hour.

Ultraviolet germicidal lamps can be installed inside the clean workbench.

Thereby stimulating the oxygen molecules in the air to form ozone molecules, this gas component has a strong bactericidal effect, can hail the shed to make the ultraviolet light directly to the place to produce a sterilization effect, but also pay attention to the personnel in the rest of the work to turn off the sterilization source lamp, to avoid burning and endangering health, hope

It can provide a local clean workspace of 1-100 grades, and is widely used in many industries such as optoelectronics, semiconductors, and precision instruments because of its high cleanliness and mobile flexibility. The high-quality centrifugal fan has low noise and long life, and the electrostatic spraying on the surface of the main body is beautiful and durable and can suppress the growth of bacteria. Equipped with an intelligent LCD screen, real-time monitoring of the working status, the operator is watching the stool.

What are the characteristics of the clean workbench?

It is widely used in laboratories, biopharmaceuticals, optoelectronic industries, microelectronics, hard disk manufacturing and other fields that need to be purified. The horizontal flow clean workbench has the advantages of high cleanliness, can be connected to the assembly line, low noise, and can be moved.

Features: 1. The fan adopts a direct-drive high-efficiency centrifugal air disruptor machine made in Germany, which has the characteristics of long life, low noise, maintenance-free, low vibration, and stepless speed regulation. The working life is up to 30,000 hours or more.

The speed regulation performance of the fan is stable, and the air volume can still be guaranteed under the state of the final resistance of the high-efficiency filter.

2. The American AAF ultra-thin partitionless filter is used to reduce the size of the static pressure box to the minimum, and then equipped with stainless steel countertop and glass side baffle to make the whole studio appear spacious and bright.

3. It is equipped with the American DWYER differential pressure gauge, which clearly indicates the pressure difference on both sides of the high-efficiency filter, and reminds to replace the high-efficiency filter in time.

4. The stepless adjustable air volume air supply system is used to adjust the wind speed, so that the wind speed in the working area is in an ideal state.

5. It is convenient to disassemble the coarse filter with large air volume pre-filtration, which can better protect the high-efficiency filter and ensure the wind speed.

6. Horizontal manifold, open table, easy to operate.

7. Before leaving the factory, the products are strictly inspected according to the American federal standard 209E, which is extremely reliable.

8. It is especially suitable for assembling into an ultra-clean production line, which can be arranged as a single unit according to the needs of the process, or multiple units can be connected in series to form a 100-level assembly line.

The above is answered by Anhui people and purification for you.

In the clean room (dust-free workshop), although a certain degree of cleanliness has been obtained, some production processes also need to be used with clean workbenches, laminar flow hoods, weighing tables, etc., in order to achieve local high cleanliness levels. So what does a clean bench look like? What are the types?

Clean workbench, also known as ultra-clean workbench, with wheels at the bottom, can be used as a single unit according to the need, or multiple units can form a clean assembly line, very flexible, can quickly reach 1-100 local clean space, so it is widely used in optoelectronics, semiconductors, microelectronics, precision instruments, delicate laboratories, biopharmaceuticals and other fields. The clean workbench in the clean room is divided into several types, including vertical flow type and horizontal flow type, among which vertical flow is more common, and it is divided into unilateral operation type, bilateral operation type, return air type and so on.

The vertical flow type of clean table is constructed with a high-efficiency filter on the top and a stainless steel operating table below, and the air forms a vertical clean airflow from top to bottom. Place small items on a stainless steel table and blow them while working. The clean workbench is equipped with an LCD control touch screen, which can switch on and off the fan, lighting, sterilization, and fault alarm.

Next to the LCD touch screen is generally a differential pressure gauge, which is used to detect the working condition of the clean area.

Among them, the unilateral and bilateral vertical flow clean workbench are all fans at the top of the vertical bend, and the inhaled air first passes through the primary filter, and then passes through the high-efficiency filter, and then forms a clean air flow to blow downward. There is no need for return air underneath the stainless steel table. The difference between unilateral and bilateral is that the middle of the bilateral vertical flow clean workbench is a square tube support, and there are filters and fans on both sides, which can accommodate two people who are working in a boring position to operate each other.

In this way, it is more space-saving when combined into an assembly line.

The return air type vertical flow clean workbench, under the stainless steel table is the return air primary filter, and the fan. The dirty air is filtered through the initial effect, driven by the fan, from the bottom to the top, and then filtered through the high-efficiency filter, and then formed a clean air flow to blow out. This creates a cycle.

Among them, the return air type clean workbench can also be equipped with a lifting door to form a closed lifting door clean workbench, prolong the service life of the high-efficiency filter, especially suitable for use in ordinary environments.

The clean vertical dressing Hu workbench uses the high-efficiency air filter purification unit to create a high-level clean area, which is suitable for low-level fast-assembly modular clean rooms, and places with high cleanliness requirements for local working environments, which can save a lot of initial investment and operating costs. This equipment is widely used in biopharmaceutical, LCD, CMOS, residual hard drives, laboratory rooms, aseptic packaging and other industries.
