Product Description

SPCC 2.0mm*1250mm Patterned PPGI Chromic Acid Surface Treatment For Home Appliances

SPCC PPGI refers to Pre-Painted Galvanized Iron/Steel that is manufactured using SPCC (Steel Plate Cold Rolled Commercial) as the base material. Here's a description of SPCC PPGI:
1. Base material: SPCC PPGI is made from cold-rolled steel plates with the SPCC grade. SPCC is a commercial quality cold-rolled steel grade specified by the Japanese Industrial Standards (JIS). It has excellent formability, surface finish, and dimensional accuracy.
2. Galvanized coating: The SPCC base material is first hot-dip galvanized, which involves immersing the steel in a bath of molten zinc to create a protective zinc coating. The galvanized coating provides corrosion resistance, preventing the underlying steel from rusting and extending its lifespan.
3. Pre-painted coating: After the galvanizing process, the SPCC steel is further coated with a pre-painted layer. This layer consists of multiple layers, including a primer and a topcoat, which are applied to the galvanized surface. The pre-painted coating provides additional protection against corrosion, enhances the aesthetic appearance, and offers customizable colors and finishes.
SPCC PPGI offers the benefits of both galvanized steel, with its excellent corrosion resistance, and pre-painted coating, with its aesthetic appeal and additional protection. It provides a durable and visually appealing solution for applications that require a combination of these properties.

1. Formability: SPCC steel, being a low carbon cold-rolled steel, possesses good formability. It can be easily shaped, bent, or formed without cracking or fracturing. This formability is advantageous during the manufacturing and installation processes, as SPCC PPGI can be fabricated into various shapes and configurations.
2. Corrosion resistance: SPCC PPGI benefits from the inherent corrosion resistance of galvanized steel. The hot-dip galvanized coating on the SPCC base material provides protection against corrosion, preventing the underlying steel from rusting. This corrosion resistance is further enhanced by the pre-painted coating applied on top of the galvanized layer.
3. Durability: SPCC PPGI exhibits excellent durability due to the combination of galvanized steel and the pre-painted coating. The galvanized coating provides long-lasting corrosion protection, while the pre-painted coating enhances the resistance to environmental factors, such as UV radiation and weathering. This results in a durable and long-lasting finish that requires minimal maintenance.
4. Aesthetic appeal: The pre-painted coating on SPCC PPGI allows for a wide range of customizable colors and finishes. This makes it suitable for applications where an attractive appearance is desired, such as building exteriors, roofing, or cladding. The pre-painted coating also provides a smooth and uniform surface finish.

The Surface Treatment of PPGI

PPGI (Pre-Painted Galvanized Iron/Steel) typically undergoes various surface treatments to enhance its performance and improve its aesthetic appearance. The specific surface treatment processes applied to PPGI can vary depending on the manufacturer and intended application. Here are some common surface treatments for PPGI:
1. Cleaning and degreasing: Before any surface treatment, PPGI undergoes a cleaning and degreasing process to remove dirt, oils, and other contaminants from the surface. This ensures proper adhesion of subsequent coatings and treatments.
2. Chemical pre-treatment: PPGI may undergo a chemical pre-treatment process to enhance its corrosion resistance and promote adhesion of the subsequent paint coating. This treatment typically involves the application of a chemical solution containing phosphates or chromates to form a thin conversion coating on the surface. The conversion coating improves the bonding between the paint and the PPGI substrate.
3. Primer coating: After the chemical pre-treatment, a primer coating is applied to the PPGI surface. The primer acts as a bonding layer between the substrate and the final paint coating. It enhances the adhesion of the paint, improves corrosion resistance, and provides a smooth and even surface for the topcoat.
4. Topcoat paint application: The final surface treatment of PPGI involves the application of the topcoat paint. The topcoat provides the desired color, aesthetics, and additional protection to the PPGI. The paint is applied using various methods, such as coil coating or spray coating, and may undergo curing or drying processes to ensure proper adhesion and durability.
5. Embossing or texturing: In some cases, PPGI may undergo additional surface treatments to create specific patterns, textures, or embossed designs on the surface. This process involves the use of embossing rollers or other mechanical methods to impart desired textures or patterns onto the PPGI.

1. Embossing or texturing: In some cases, PPGI may undergo additional surface treatments to create specific patterns, textures, or embossed designs on the surface. This process involves the use of embossing rollers or other mechanical methods to impart desired textures or patterns onto the PPGI.
2. Roofing and Cladding: Patterned PPGI is often used for roofing and cladding applications in residential, commercial, and industrial buildings. The embossed patterns provide a decorative element to the roof or wall panels, enhancing the overall appearance of the structure. It can be used for applications such as roof tiles, corrugated sheets, or wall cladding.
3. Furniture and Decorative Items: Patterned PPGI is used in the production of furniture and decorative items. It can be applied to tables, cabinets, shelves, and various other furniture pieces to add texture and visual interest. Patterned PPGI is also used in the manufacturing of decorative items such as lamps, frames, and signage.
