Recently, at Shandong Linghang Aluminum Co., Ltd., workers were affixing English labels to finished aluminum sheets, destined for export to Africa and the Middle East. "Our company's independently developed production process strictly controls the flatness of the aluminum sheets, ensuring they meet international standards," Vice President Yang Yong told reporters. "Our monthly export volume reaches 800 tons." "The aluminum market is extremely competitive. To survive, small and medium-sized enterprises must first learn to navigate the pain and transform." With only a year of operation under its belt, Linghang Aluminum has rapidly established itself in the market through technological innovation, becoming one of only 10 companies nationwide exporting aluminum sheets.

Recently, at Shandong Linghang Aluminum Co., Ltd., workers were affixing English labels to finished aluminum sheets, destined for export to Africa and the Middle East. "Our company's independently developed production process strictly controls the flatness of the aluminum sheets, ensuring they meet international standards," Vice President Yang Yong told reporters. "Our monthly export volume reaches 800 tons." "The aluminum market is extremely competitive. To survive, small and medium-sized enterprises must first learn to navigate the pain and transform." With only a year of operation under its belt, Linghang Aluminum has rapidly established itself in the market through technological innovation, becoming one of only 10 companies nationwide exporting aluminum sheets.

The influx of leading talent has quickly catapulted Linghang to prominence. From its inception, Linghang hired over 30 highly paid technicians from across the country, including current Vice President of Technology Meng Qingfu, who receives a State Council subsidy. After the company decided to produce aluminum sheet, strip, and foil, Meng Qingfu led his R&D team to meticulously develop a production process for over two months, achieving a flatness of less than 15 IRI (Infrared Recognition Index), more than three times the accuracy of competitors. This effort immediately won the favor of international clients. Having tasted the sweetness of new product development, Linghang continued its efforts, developing aluminum sheet just 0.006mm thick, with an accuracy of ±0.001mm, quickly gaining an industry lead. Simultaneously, Meng Qingfu and his technical staff continuously innovated and, after repeated testing, developed an extremely lightweight aluminum veneer suitable for use in high-speed rail, airports, and modern high-rise buildings. With a recycling rate of over 85% after smelting, it generates nearly 200 million yuan in additional annual profits for the company. "Talent strengthens the county, and science and technology prospers Chiping." Chiping County firmly adheres to the principle of transforming its industrial structure and adjusting its economic structure, focusing on upgrading traditional industries and cultivating and strengthening strategic emerging industries. The County actively recruits talented individuals, attracting leading figures from both home and abroad. A number of high-tech projects, driven by leading talent, have grown rapidly, driving the accelerated development of emerging industries within the county, such as aluminum powder deep processing and new aluminum alloy materials, which possess core technologies and independent intellectual property rights. A model has taken shape, where technology drives the establishment of high-end industrial projects. To date, these leading talents have spearheaded over a hundred innovative and entrepreneurial projects across the county.

Like Linghang Company, more and more Chiping companies are reaping the benefits of attracting high-end talent. With the help of Professor Gao Qirui and his team from the Plastics Laboratory of Qingdao University of Science and Technology, Shandong Yihe Plastics has developed an environmentally friendly, flame-retardant composite material that fully meets EU standards for oxygen index, elasticity, and hardness, becoming the sole domestic supplier of air conditioner seals for Hitachi and Mitsubishi. Xinfa Shengji has introduced Professor Wang Wenlong's research on red mud-based sulphoaluminate specialty cement production, developing a new raw material preparation process called "wet grinding-homogenization-filtration," which can fully utilize 300,000 tons of red mud annually, generating over 100 million yuan in revenue.

1. What causes scratches or color differences on the surface of aluminum panels? How can they be avoided?

Causes: ① Inadequate protection during transportation/installation, resulting in collisions and friction between panels; ② Differences in coating processes (such as spraying temperature and paint mixing ratio) between different batches of products. Solutions/Preventions: ① Wrap the products with pearl cotton and bubble wrap during transportation, and handle them gently while wearing gloves during installation; ② Clearly specify the "same batch production" requirement to the manufacturer, and verify the batch number upon receipt.

2. The aluminum panel is labeled as "2.5mm thick", but the actual thickness is less than 2.5mm. Is this due to shoddy workmanship?

Not necessarily; it's important to distinguish between "substrate thickness" and "overall thickness": The industry-standard "thickness" usually refers to the substrate thickness (for the pure aluminum plate portion). The surface coating (such as fluorocarbon paint or polyester paint) thickness is approximately 0.02-0.05mm, which will result in the overall measurement value being slightly higher than the substrate thickness, but not lower.

3. What should be done if aluminum panels deform or bulge after installation?

Causes: ① Excessive keel spacing (e.g., using keel spacing >1.2m for large-sized panels), resulting in uneven stress on the panels; ② Inappropriate panel selection (e.g., using a substrate <2.0mm thick for large outdoor spans); ③ Overtightening screws during installation, compressing the panels. Solutions: ① Modify the keel structure, reducing the spacing as recommended by the manufacturer (e.g., for 2.5mm thick panels, keel spacing ≤1.0m); ② Replace with thicker substrate panels that meet the size requirements; ③ Readjust screw tightness to ensure the panels naturally conform to the keel.

4. What could be causing the aluminum panel exterior wall to leak during rainy weather? How can it be repaired?

Core causes: ① Aging or cracking of the sealant in the joints, or improper application (e.g., the sealant strip is not compacted, leaving gaps); ② Lack of waterproofing reinforcement at corners, window sills, and other joints. Repair methods: ① Remove the aged sealant and reapply weather-resistant silicone sealant (compliant with GB/T 14683 standard), ensuring the sealant joints are full and free of air bubbles; ② Apply waterproof membrane to corners, and slope the window sills outwards (slope ≥ 5°) to prevent water accumulation.

5. Will aluminum panels rust over time? How should they be cleaned and maintained?

Rusting: The aluminum composite panel substrate is made of aluminum alloy, which forms a dense oxide film on the surface, making it resistant to rust. However, if the coating is damaged (e.g., scratches exposing the substrate), prolonged exposure to rain may cause localized corrosion, requiring timely repainting. Daily Maintenance: ① Clean with a neutral detergent and a soft cloth (e.g., diluted dish soap). Avoid using strong acids/alkalis (e.g., toilet cleaner) or steel wool to prevent damage to the coating. ② Inspect outdoor panels every 1-2 years and repair any coating damage or aging sealant promptly.

6. How is the fire resistance of aluminum composite panels? Can they pass fire safety inspection?

The base material of aluminum single-panel panels (aluminum alloy) is a non-combustible material, and the surface coating (fluorocarbon paint, polyester paint) is mostly "fire-retardant B1 grade", which meets the fire protection requirements of most buildings (such as exterior walls and ceilings); Note: Some special locations (such as kitchens and electrical rooms) have higher fire protection requirements, requiring the customization of "fire-retardant coated aluminum single panels" from the manufacturer, and a fire protection test report must be provided.
