Temporary Structures: Modular homes, emergency shelters, etc., for scenarios requiring quick setup.

Moreover, due to their ease of transport and installation, sandwich panels have gained popularity in the prefabricated building market. They significantly shorten construction timelines and reduce wet trades associated with traditional masonry walls, thereby minimizing on-site pollution and noise.

 

 

Conclusion

In summary, as a versatile building component, sandwich panels, with their outstanding physical properties, convenient installation methods, and environmental benefits, have become an indispensable part of modern architecture. With the advancement of technology, we can anticipate more innovative sandwich panel products entering the market, bringing greater possibilities to our living spaces.

Walking on a sandwich panel roof can be possible, but it depends on various factors such as the design of the roof, the thickness and strength of the panels, the weight and distribution of the load, and the specific application requirements.

Sandwich panel roofs are lightweight and composed of two external metal sheets with a rigid foam insulation core in between. While they are designed to provide structural support and insulation, they may not be intended to support heavy loads or foot traffic.

If the sandwich panel roof has been specifically designed and certified to withstand walking or occasional maintenance activities, it may be safe to walk on. In such cases, the manufacturer or structural engineer would typically provide guidelines regarding weight restrictions, permissible load distribution, and recommended walking paths to minimize any potential damage.

What I can tell you is that Wiskind Roof Panel, like BiLAP, admits that people(150kg) walk on it. Do not worry about its quality. Wiskind Poof Sandwich Panel used ≥100 kg/m³rock wool as core material. And other Roof Panel used rock wool as core material, and used≥38kg/m³PU as sealing. If you are focused on the fireproof ability, rockwool panel is the best choice. If you pay attention to the thermal insulation, you can choose rockwool and PU sealing.

A pass box is a widely used transfer device in cleanrooms, designed for transferring items between the cleanroom and external areas or between areas within the cleanroom with different cleanliness levels. Its purpose is to prevent contaminants from entering the cleanroom, thus ensuring the stability of the clean environment. Below is a technical article on pass boxes, detailing their functions and working principles.

 

Technical Analysis of Pass Boxes

 

1. Definition and Function of Pass Boxes

A pass box, also known as a transfer hatch, is a critical component in cleanrooms. It serves as an isolated passage for transferring items between different areas of varying cleanliness levels, or between clean and non-clean areas. The primary function of a pass box is to minimize contamination risks during transfers, ensuring a stable clean environment inside the cleanroom.

The key functions of a pass box include:

Contamination Prevention: Cleanroom Pass boxes prevent contaminants from entering or exiting the cleanroom by isolating the transfer process.

Air Filtration: Many pass boxes are equipped with air filters, such as HEPA or ULPA, to ensure clean air circulation within the pass box.

Separation of Personnel and Material Flow: By allowing only materials to be passed through, pass boxes separate human traffic from material flow, improving the efficiency of cleanroom operations.

 

2. Types of Pass Boxes

Pass boxes come in several types, tailored to different applications and structural needs:

Mechanical Interlock Pass Boxes: These use a mechanical system to ensure that only one door can open at a time, preventing direct air exchange between the cleanroom and non-cleanroom areas.

Electronic Interlock Pass Boxes: An electronic system controls the interlocking doors for higher precision and security, suitable for high-demand environments.

Air Shower Pass Boxes: These contain a built-in air shower system that removes dust and contaminants from items’ surfaces during the transfer process, making them ideal for ultra-clean environments.

 

3. Working Principles of Pass Boxes

The pass box operates on an interlock mechanism and includes an air filtration system to ensure cleanliness during the transfer process. The working process includes the following steps:

Interlock Door Control: Pass boxes typically have two doors: one facing the cleanroom and one facing the external area. An interlock system—either mechanical or electronic—ensures only one door opens at a time, which prevents cross-contamination.

Air Filtration: The pass box may include HEPA or ULPA filters to purify the air inside. Some models also feature an air shower system that blows air onto items to remove dust or other particles.

Transfer Procedure: During transfer, one door opens for the item to be placed in the pass box. The first door is then closed before the opposite door can be opened, allowing items to enter or exit without compromising the cleanroom's air quality.

 

4. Installation and Maintenance of Pass Boxes

Pass boxes should be installed in high-traffic transfer points according to cleanroom layout requirements. Regular inspections and maintenance of interlock mechanisms, air filtration systems, and air shower units are essential for optimal operation.

 

5. Applications of Pass Boxes

Pass boxes are widely used in several industries to control contamination and ensure product quality:

Semiconductor Manufacturing: Used to transfer delicate components like wafers, reducing the risk of particle contamination.

Pharmaceutical Industry: Ensures aseptic conditions by transferring drugs and instruments without introducing contaminants.

Food Processing: Prevents dust and microbial contamination of raw materials during transfer.

A cleanroom is a specially designed environment where the concentration of airborne particles is controlled to ensure a contamination-free space. Cleanrooms are commonly used in industries that require strict control over environmental pollutants, such as dust, airborne microbes, aerosol particles, and chemical vapors. These environments are essential in sectors like pharmaceuticals, biotechnology, electronics, aerospace, and food processing, where even the smallest contaminant can compromise product quality or pose a safety risk.

The filtration system is often designed with positive pressure to prevent unfiltered air from entering.

2. Temperature and Humidity Control

   Temperature and humidity levels are carefully controlled to meet specific requirements for different industries. For example, in the pharmaceutical industry, humidity control is critical to prevent moisture-sensitive materials from degrading.

3. Controlled Access

   To minimize contamination, access to a cleanroom is highly restricted. Personnel must wear special garments, including gloves, masks, and coveralls, which prevent particles from their bodies from contaminating the air. Some cleanrooms also have air showers at the entrance to remove any dust particles from people before they enter.

4. Surface Materials

   All surfaces within a cleanroom, such as walls, ceilings, and floors, are made from materials that do not shed particles and are easy to clean. The goal is to ensure that the room remains as sterile as possible during operation.

 

Cleanroom Classifications

Cleanrooms are classified based on the number and size of particles allowed per cubic meter of air. The most widely used classification system is the ISO 14644-1 standard, which divides cleanrooms into nine different classes, ranging from ISO Class 1 (the cleanest) to ISO Class 9 (least clean). The classification depends on the specific industry and product requirements.

For instance:

- ISO Class 1 is used for manufacturing sensitive products like semiconductors.

- ISO Class 5 is common in pharmaceutical production.

 

Applications of Cleanrooms
