Desarrollo de la industria de la línea de extrusión de láminas ACP

Resumen

In the field of China’s extruder industry, there is also a large gap in the actual demand for different products. Therefore, on the basis of different product requirements, the structure of the host also has great differences. Extruders can be applied to the production of different products such as blown film sheets or sheets. The traditional host form often chosen in the field of ACP sheet is mainly the ACP Sheet Extrusion Line. But now the twin-screw main machine has become a common choice for extruders in China. Even the market share has far exceeded the share of the single-screw main engine. So what about the ACP Sheet Extrusion Line under the innovative breakthrough of China JWELL?

Introduction to ACP Sheet Extrusion Line

Aluminum-plastic composite panel, referred to as ACP, is a composite material made of chemically treated coated aluminum plate as the surface material, polyethylene plastic or high mineral as the core material, and processed in the special ACP Sheet Extrusion Line.

It is composed of two materials (metal and non-metal) with completely different properties. It not only retains the main characteristics of the original composition material (metal aluminum, non-metallic polyethylene plastic), but also overcomes the shortcomings of the original composition material, thereby obtaining many Excellent material properties, such as luxury, bright and colorful decoration, weather resistance, corrosion resistance, impact resistance, easy processing and molding, easy handling and installation, etc. Therefore, aluminum-plastic composite panels are widely used in all aspects of various architectural decorations in China, and have become one of the representatives of metal curtain walls.

The properties of ACP Sheet Extrusion Line are as follows

• Strong peeling degree: ACP Línea de extrusión de láminas adopts a new process to improve the most critical technical index of aluminum-plastic composite panel-peel strength to an excellent state, so that the flatness, weather resistance and other properties of aluminum-plastic composite panels are improved. Increase accordingly.

• Impact resistance: strong impact resistance, high toughness, no damage to the topcoat in bending, strong impact resistance, and no wear caused by wind and sand impact in areas with large sandstorms.

• Weather resistance: Due to the unique advantages of PVDF fluorocarbon paint and weather resistance, it will not damage its beautiful appearance in hot sunlight or severe cold wind and snow, and it will not fade for 20 years.

• The coating is uniform in color and diverse: After chemical treatment and the application of Henkel’s film technology, the adhesion between the paint and the aluminum-plastic panel is uniform and uniform, and the colors are diverse.

• The material is easy to process: the weight per m² of the aluminum composite panel is only about 3.5 ~ 5.5ka, and it is easy to dry and handle. Various changes can be made, and it can also be cold-formed, cold-folded, cold-rolled, riveted, screwed, or glued. Because of its easy installation, it can reduce construction costs.

ACP Sheet Extrusion Line Product Technology and Classification

1. Classification by product function of ACP Sheet Extrusion Line

• Fireproof board: choose flame retardant core material, and the combustion performance of the product reaches flame retardant grade (B1 grade) or non-combustible grade (A grade).

• Anti-bacterial and mildew-proof aluminum-plastic board: Coating the antibacterial and bactericidal effect on the aluminum-plastic board.

• Anti-static aluminum composite panel: The aluminum composite panel is coated with antistatic paint, so it is not easy to generate static electricity, and the dust in the air is not easy to adhere to its surface.
  

  2. According to the surface decoration effect of ACP Sheet Extrusion Line

• Coated decorative aluminum-plastic panel: Coating various decorative coatings on the surface of aluminum panel. Commonly used are fluorocarbon, polyester, acrylic coatings.

• Anodized aluminum composite panel: ACP Sheet Extrusion Line adopts anodized aluminum alloy panel in time, with red, bronze and other colors.

• Film decorative composite board: The color pattern film is adhered to the aluminum plate coated with primer or directly attached to the degreased aluminum plate according to the set process conditions and relying on the action of the adhesive.

• Color printing aluminum-plastic board: Different patterns are printed on the transfer paper with different patterns through computer imagesetter printing technology, and various imitation natural patterns are printed on the transfer paper, and then various patterns are indirectly copied on the aluminum-plastic board through thermal transfer technology. Imitation of natural patterns.

• Brushed aluminum composite panel: ACP Sheet Extrusion Line uses an aluminum alloy panel with a brushed surface, which is usually a gold-silver brushed product.

• Mirror aluminum composite panel: The surface of the aluminum alloy panel is polished to look like a mirror.

ACP Sheet Extrusion Line Product Notes

1. Aluminum composite panels should be stored in an appropriate way or installed in a dry and ventilated place to avoid accumulation of water, and the ambient temperature should not be higher than 70oC. Avoid installing in abnormal environments, such as smoke, sand, radiation, harmful gases and chemicals.

2. ACP Sheet Extrusion Line should be placed flat during transportation or storage. When handling, the 4 sides of the board must be lifted at the same time, and do not drag on one side to avoid scratching the board surface.

3. When grooving with a slotting machine or a gong machine, a round head or a V-shaped flat head saw blade or milling cutter with a diameter of ?90o should be used for slotting, and a 0.2–0.3mm thick plastic core board should be left to bend together with the panel. , to increase strength and toughness and prevent hydrogenation of aluminum flakes. Bending too sharply or cutting damage to the aluminum panel or leaving too thick plastic will cause the aluminum panel to break or the paint film to burst during bending.

4. It is necessary to use even force when bending the edge, forming at one time, do not bend repeatedly, otherwise the aluminum panel will be broken.

5. In order to maintain the flatness of the ACP Sheet Extrusion Line and enhance its wind resistance, the aluminum-plastic board needs to be lined with a skeleton and glued to the board after being bent.

6. When it is used for arc surface decoration, bending equipment should be used to bend the aluminum-plastic panel, and force should be applied slowly to make the panel gradually reach the required curved surface, not in one step.

7. Install the aluminum composite panel on the same plane in the same process direction. Otherwise, the visual character may be poor.

8. The protective film should be torn off within 45 days after the aluminum composite panel is installed, otherwise, the protective film will age due to long-term exposure to sunlight. Glue retention may occur when the film is torn off.

9. Inner wall panels should be used indoors and should not be installed outdoors to ensure their service life.

10. If the surface of the ACP Sheet Extrusion Line is polluted during construction or use, it can be gently cleaned with neutral detergent or alcohol. Avoid using strong acid or strong alkaline detergent.

In recent years, as a China Plastic Extruder manufacturer, JWELL’s ACP Sheet Extrusion Line has been favored by many manufacturers, and more and more production lines have begun to incorporate such exclusive extruders. Under such many advantages, the development of this JWELL extruder and its position in the industry have been achieved. For production enterprises, being able to choose reliable machinery and equipment is the basis for ensuring high-efficiency production and production safety in the production process. It is also the basis for ensuring the quality of the products produced.
