1. Air conditioning and ventilation fans must be turned off during the sealing and testing process, unless specifically required by central air conditioning systems or customer instructions. In such cases, a written record must be maintained.
2. Avoid any activities that could interfere with test results during the sealing and testing phase, such as smoking, using air fresheners, pesticides, or air purifiers. These can introduce contaminants and affect accuracy.
3. The testing area should be thoroughly cleaned before the process begins. No leftover materials like paint, coatings, or debris should remain on the floor or surfaces.
4. Do not use chemical products such as perfumes, air fresheners, or other scented items during the sealing and testing phases, as they may compromise the integrity of the test environment.
5. Ensure all doors in each room are closed tightly during the test to prevent air leakage. Maintain a sealed environment and avoid any unnecessary ventilation.
6. For air sampling at the door, each test point typically requires about 20 minutes for accurate data collection. This ensures proper air flow and sample representation.
7. The CMA report will be delivered approximately two working days after the sampling is completed. This timeline allows for thorough analysis and quality checks before finalizing the results.
Additional notes: Always follow the guidelines provided by the testing authority. If there are any uncertainties or special conditions, consult with the responsible personnel before proceeding. Maintaining a clean, controlled, and stable environment is essential for reliable and consistent test outcomes.
The use of water glass is very extensive, almost throughout the national economy of each department. In the chemical system is used to manufacture silica gel, silica black, zeolite molecular sieve, sodium metasilicate, silica sol, layer silicon and instant powder sodium silicate, sodium potassium silicate and other silicate products, is the basic raw material of silicon compounds. In the economically developed countries, the series of deep processing products with sodium silicate as raw material has developed to more than 50 kinds, some of which have been applied in the fields of high, fine and advanced science and technology; In light industry is washing powder, soap and other detergents indispensable raw materials, but also water softener, sink aid; In the textile industry for dyeing, bleaching and sizing; It is widely used in casting, grinding wheel manufacturing and metal preservative in mechanical industry. In the construction industry, it is used to manufacture quick-drying cement, acid-proof cement waterproof oil, soil curing agent, refractory materials, etc. In agriculture, silicon fertilizers can be made; In addition, it is used as silicon aluminum catalyst for petroleum catalytic cracking, filler of soap, adhesive of corrugated paper, metal preservative, water softener, detergent agent, refractory materials and ceramic raw materials, bleaching, dyeing and slurry of textiles, mine dressing, waterproof, plugging, wood fire prevention, food anti-corrosion and adhesive.
