The completion acceptance of a clean room and its associated cleaning plant is typically conducted through individual machine testing at each branch, without prior testing after the system's self-test under production load. The final acceptance process involves verifying the results of single-machine tests, no-load system tests, performance parameter assessments of the clean room (or area), quality inspections of each section, and functional testing as required.
When the clean facility is ready for final acceptance, it is essential to carefully review all relevant documentation, which generally includes:
1. Records of drawing reviews, design change notices, and as-built drawings;
2. Factory certificates and entry inspection reports for major equipment, materials, and instruments used in each divisional project;
3. Installation and inspection records for individual equipment and systems in each section;
4. Records of single-machine test runs for each branch;
5. No-load trial operation and commissioning records for each project and system;
6. Test and inspection records for various types of pipelines;
7. Inspection and commissioning records for safety facilities in each section;
8. Quality acceptance records for each divisional project.
The main testing items during the completion acceptance of the clean room include:
1. Visual inspection of airflow patterns;
2. Measurement of wind speed and air volume;
3. Leak detection in air filters;
4. Sealing test of the clean room or zone;
5. Pressure difference test between rooms;
6. Air cleanliness level assessment;
7. Self-cleaning time measurement;
8. Temperature and relative humidity testing;
9. Illuminance level evaluation;
10. Noise level measurement;
11. Additional testing items specified by the client.
Once the clean room has passed the initial acceptance, function acceptance is carried out as required, typically under "static" conditions. The primary test items during this phase include:
1. Detection of air cleanliness levels;
2. Microbiological, chemical contaminant, or surface cleanliness testing if required by the production process;
3. Stability testing of temperature and humidity in the clean room;
4. Measurement of self-cleaning time;
5. Airtightness testing of the clean room;
6. Illuminance measurement;
7. Noise level confirmation;
8. Verification and recording of airflow patterns and air change rates as needed;
9. Other specific testing requirements.
After the acceptance process is completed, a detailed acceptance report must be prepared. This report should include:
1. A description of the operational status of all facilities, including production equipment;
2. Information about personnel and their activities within the clean room area;
3. Sub-test records along with analysis and comments, including test point locations and coordinates;
4. Valid calibration certificates for all testing instruments;
5. Conclusions from the acceptance process and final approval.
This thorough documentation ensures that the clean room meets all necessary standards and is fully functional for its intended purpose.
Material: Ceramic pot feet are typically made from the same materials as ceramic pots themselves. They are crafted from clay-based ceramics and fired at high temperatures to ensure durability and strength. This allows them to withstand the weight of the pot and plant while providing stability and support.
Design: Ceramic pot feet come in various designs, ranging from simple geometric shapes to more intricate decorative motifs. They may feature rounded, square, or cylindrical forms, often with textured surfaces or embellishments that complement the aesthetic of the pot they support. Some pot feet designs may also incorporate patterns or reliefs that mimic natural elements like leaves, flowers, or animals.
Size: Ceramic pot feet are available in different sizes to accommodate pots of various diameters and weights. They typically have a flat top surface to provide stable contact with the bottom of the pot and a wider base for enhanced stability on the ground or other surfaces.
Function: The primary function of ceramic pot feet is to elevate the pot slightly above the ground or surface on which it sits. This elevation helps to improve drainage and airflow around the pot, preventing waterlogging, soil compaction, and root rot. By allowing air circulation beneath the pot, pot feet also help to prevent the formation of mold, mildew, and pests.
Protection: Ceramic pot feet serve as a protective barrier between the pot and the surface below, reducing the risk of damage to both the pot and the underlying surface. They help to prevent moisture accumulation, staining, and potential deterioration caused by prolonged contact with moisture or abrasive surfaces.
Aesthetic Enhancement: In addition to their functional benefits, ceramic pot feet can enhance the visual appeal of potted plants by adding a decorative element to the display. They can complement the design of the pot and contribute to an overall cohesive look in garden settings, patios, balconies, or indoor spaces.
Versatility: Ceramic pot feet can be used with a wide range of ceramic pots, planters, and containers, as well as other materials such as terra cotta, stone, or metal. They are suitable for both indoor and outdoor use and can be easily removed or repositioned as needed.
Overall, ceramic pot feet provide a practical and aesthetically pleasing solution for elevating and protecting ceramic pots while promoting healthy plant growth and enhancing the visual appeal of potted plant displays.
