On January 1, the Regional Comprehensive Economic Partnership (RCEP) came into effect. The latest statistics from China Customs show that in the first quarter of this year, China's total import and export value to the other 14 RCEP member countries increased by 6.9% year-on-year, accounting for 30.4% of China's total foreign trade value in the same period. In the first quarter, China's import and export growth with South Korea, Malaysia, New Zealand and other countries exceeded double digits year-on-year.

"Asian Economic Prospects and Integration Process 2022 Annual Report" pointed out that the official entry into force of RCEP marks the start of the world's most populous and largest economic and trade free trade zone. Even in the face of the impact of the new crown pneumonia epidemic, the pace of Asia-Pacific economic integration has not stopped. Whether it is economic recovery or institutional building, the Asia-Pacific region has provided new impetus to the world.

"The first year of RCEP has shown a good momentum of development." Xu Xiujun, a researcher at the Institute of World Economics and Politics of the Chinese Academy of Social Sciences, pointed out in an interview with this reporter that the Asian region includes developed countries such as Japan, South Korea, and Singapore, as well as China and India. China presents a unique pattern with strong complementarity and diversity. RCEP is a higher standard and higher-level integration of economic and trade resources for economies in the Asia-Pacific region, making economies at different positions in the industrial chain more closely linked. Under such circumstances, the driving and leading role of East Asia in the global economy has been further strengthened.

"RCEP is the first regional trade agreement that includes the three major economies of China, Japan and South Korea. It establishes free trade relations between China, Japan, Japan and South Korea for the first time, marking a milestone step in the regional economic integration of East Asia." China Modern International Relations In an interview with this reporter, Chen Fengying, a researcher of the research institute, pointed out that the most worthy of attention of RCEP is the rule of origin accumulation, that is, when determining the origin of goods, if products from other parties to the agreement are used, it is allowed to transfer the other parts of the free trade agreement. Products processed by a Party using non-originating materials accumulate to the final product. If the final product produced by the enterprise reaches more than 40% of the regional value of all the countries in which the agreement is in force, it can obtain the RCEP origin qualification. This rule allows the value components from any member of RCEP to be taken into account, greatly improving the utilization rate of preferential tax rates in the agreement, and consolidating the foundation of the supply chain and industrial chain in the Asia-Pacific region.

Gas springs are a versatile and essential component used in a wide range of applications, from automotive hoods to medical equipment. When it comes to purchasing gas springs, one of the most common questions is about their lifespan. Unfortunately, there is no straightforward answer, as it depends on various factors such as usage, environment, and maintenance. In this article, we will delve into the factors that influence the longevity of gas springs and provide helpful tips on how to extend their lifespan.

Let's begin by understanding what gas springs actually are. Also known as gas struts, these mechanical springs utilize pressurized gas and a piston to provide controlled and consistent motion. Gas springs are favored for their reliability, ease of installation, and adjustable force capabilities, making them a popular choice across different industries.

The lifespan of a gas spring primarily depends on the specific application it is used for. The usage pattern is often a crucial determinant of its longevity. Gas springs in automotive applications like hoods and trunks typically last between five to eight years. However, gas springs employed in industrial applications, such as factory equipment or medical devices, can have longer lifespans if subject to minimal shocks, vibrations, and wear and tear.

The environment in which a gas spring operates also plays a significant role in its lifespan. Gas springs exposed to high temperatures, excessive moisture, or corrosive chemicals tend to wear out faster due to the deterioration of the outer sealing material. Additionally, gas springs in high humidity or saltwater environments are prone to rust, corrosion, and oxidation, leading to a shorter lifespan compared to those used in dry environments.

Proper maintenance and care are essential for extending the lifespan of gas springs. Regular cleaning, inspection, and lubrication are crucial maintenance practices. For heavily used gas springs, visual inspections are necessary to identify signs of wear or damage. Proactive maintenance reduces the risk of unexpected failure, prolongs the gas spring's lifespan, and enhances its overall performance.

Apart from these factors, the manufacturer also plays a pivotal role in determining the lifespan of gas springs. The choice of materials used for manufacturing the outer cylinder, piston, rod, and seals directly affects the durability and longevity of gas springs. It is crucial to select a reputable manufacturer that meets the specific requirements of the intended application.

In summary, the lifespan of gas springs varies depending on various factors, including maintenance, environment, usage, and manufacturing quality. Typically, gas springs used in automotive applications last between five to eight years. However, this can be significantly shorter or longer depending on the specific conditions. By selecting the right gas spring product, performing regular maintenance, and ensuring appropriate environmental conditions, the lifespan of gas springs can be extended, resulting in improved performance, enhanced safety, and reduced replacement costs.

In conclusion, gas springs are indispensable components in numerous applications. Understanding the factors that contribute to their lifespan and taking appropriate measures can significantly extend their working life. By considering maintenance practices, environmental conditions, usage patterns, and the choice of manufacturer, users can maximize the benefits of gas springs, ensuring optimal functionality, safety, and cost-effectiveness.

Can the spring hydraulic hinge be installed with an inner space of 8 cm?

Yes, the spring hydraulic hinge can be installed with an inner space of 8 cm. Here is a step-by-step guide on how to install the hydraulic hinge:

Hydraulic hinge installation method:

Step 1: Choose the appropriate hinge based on the design requirements of the cabinet. This includes considering whether the door panel is a full cover, a half cover, or a built-in panel, and selecting the appropriate hinge type (straight bend, medium bend, or large bend).

Step 2: Determine the edge distance of the cup hole on the door panel based on the thickness of the side plate (usually 16mm or 18mm). Typically, the edge distance is 5mm. Drill a hinge cup hole on the door panel.

Step 3: Insert the hinge cup into the cup hole of the door panel, ensuring that the hinge and the edge of the door panel form a 90-degree angle. Secure the hinge using 4X16mm self-tapping screws, tightening them with a screwdriver through the two screw holes on the hinge cup.

Step 4: Move the door panel with the locked hinges to the cabinet body and align it with the side panel. Install two long holes first to test if the top and bottom are aligned. Adjust the position of the door panel to achieve the best fit, and then drill a round hole.

Step 5: Fine-tuning is necessary. Loosen a small screw on the hinge and adjust the large screw in front to fit the side panel of the hinge cover. Use the small screw to further adjust the tightness between the door panel and the side panel.

Step 6: Test the hinge adjustment using your experience. Readjust as needed until the door panel and hinge function properly and are aligned.

How to install the spring hinge:

Before installation, ensure that the hinge is compatible with the door and window frame and leaf. Check if the hinge groove matches the height, width, and thickness of the hinge. Confirm compatibility with the screws and fasteners connected to the hinge. The connection method of the hinge should match the material of the frame and leaf.

When installing, make sure that the axes of the hinges on the same leaf are on the same vertical line to prevent issues with the door and window leaves.

Spring Hinge Installation:

Spring hinges are available in full cover, half cover, and built-in options. With full cover hinges, the door completely covers the side panel of the cabinet, leaving a gap between the two for safe opening. Half cover hinges are used when two doors share a side panel, requiring a specific total clearance between them. Build-in hinges are used when the door is inside the cabinet, next to the side panel, also requiring a gap for safe opening.

Spring hinge installation requires considering the minimum clearance, which is the minimum distance from the side of the door required for opening. The minimum clearance is determined by various factors, including the C distance, door thickness, and hinge type. Different hinge models have different maximum C sizes, with larger C distances resulting in smaller minimum gaps.

The covering distance of the door, whether full cover, half cover, or inner door, also affects the installation. Full cover refers to the distance from the outer edge of the door to the outer edge of the cabinet, half cover refers to the distance between two doors, and inner door refers to the distance from the outer edge of the door to the inner edge of the cabinet side panel.

Spring hinge installation precautions:

- Ensure the hinge matches the door and window frame and leaf.

- Check if the hinge groove matches the height, width, and thickness of the hinge.

- Confirm compatibility with screws and fasteners.

- Match the connection method of the hinge with the material of the frame and leaf.

- Identify which leaf plate should be connected with the fan and which should be connected with the door and window frame.

- Ensure the axes of the hinges on the same leaf are on the same vertical line.

- Use a 4mm hexagonal key to open the hinge while installing it.

- Avoid exceeding four rotations when adjusting the hinge.

- The opening angle should not exceed 180 degrees.

- Loosen the hinge by following the same operation as in step 1.

In conclusion, the installation of spring hydraulic hinges with an inner space of 8 cm is possible. Following the given instructions and precautions will help you ensure a successful installation.
