Frequently Asked Questions

What are the advantages of Zhihua EB four-resistant film compared to domestic EB film? Answer: Advantage 1: Zhihua is the only company in China that possesses the entire chain of imported EB four-resistant membranes

Advantage 1: Zhihua is the only enterprise in China that possesses an imported full-chain intelligent manufacturing production line for EB four-resistant film: from research and development to film production to panel lamination, all are completed in Zhihua's dust-free workshop, ensuring better quality; (Currently, domestic EB film production enterprises are all supply chain integrated enterprises, that is, the film is processed in one enterprise, the EB electron beam curing is processed in another individual enterprise, and the panel lamination is processed in yet another enterprise;); ） Advantage 2: Zhihua is the only enterprise in China that adopts a 4-layer process for its base film (GAAG film) (i.e., consisting of four layers: a surface G material layer, an upper and middle A material layer (pearl powder), a lower and middle A material layer, and a bottom G material layer). Other domestic enterprises only have three layers, with only one middle A material layer; Advantage 3: Unique metallic luster film: The metallic luster color is very soft, balanced, three-dimensional, and vivid from all angles; it completely solves the pain points in the metallic film industry, such as large color differences between batches, inconsistent colors on the horizontal and vertical cross-sections of the film material, uneven distribution of pearlescent powder, and the lack of three-dimensional effect due to pearlescent powder being applied upside down (in the traditional industry process, pearlescent powder is applied using a roller); Process principle: Zhihua metal light-sensing film, the metal pearlescent powder is evenly extruded from the "upper A material layer". The transparent layer of material G on the surface combines with the upper A material layer, leaving sufficient space for the metal pearlescent powder to create a three-dimensional effect. This creates a feeling of soft, balanced, three-dimensional, and vivid metallic flash colors from all angles.

What is the difference between EB Four-Resistant Film and EB Four-Resistant Board?

The EB four-resistant film is produced by applying the EB four-resistant electron beam curing process directly on the surface of the film material, and then attaching it to the substrate; EB four-resistant board is made by first applying a layer effect or decorative paper on the substrate, and then performing the EB four-resistant electron beam curing process on the surface;

What is PETG film?

PETG film (polyethylene terephthalate-1,4-cyclohexanedimethylene terephthalate) is a copolyester obtained by copolymerization modification of PET. Commonly known as: PETG film or PETG board. PET is the primary material used in the manufacture of mineral water bottles (the PET label can be found on the bottom of these bottles). Due to its environmental friendliness, sealing properties, and strong malleability, it has been widely used in recent years for decorative surface layers on furniture cabinets. It is commonly referred to as PET film or PET board. Compared to PET, PETG excels in terms of adhesion, transparency, hardness, rigidity, toughness, and environmental performance.

What is GAAG membrane?

The GAAG film is an EB four-layer substrate film specially developed by Zhihua. It is extruded using a four-layer process: (the surface PETG layer, commonly known as the G material layer, the upper middle APET layer, commonly known as the A material layer (pearl powder), the lower middle A material layer, and the bottom G material layer, totaling four layers). This greatly enhances the hardness and fullness of the film material, ensuring that the film adheres flatly and covers without showing through, is smooth, and free of indentation. At the same time, it retains the flexibility of the film material, making it possible for the film to be wrapped and bent without cracking; most other film materials in the industry use a three-layer process.

What is the difference between EB four-resistant film and PETG film?

EB Four-Resistant Film is produced by applying a special EB coating on the surface of GAAG film, followed by EB Four-Resistant Electroplating The sub-beam curing process (curing degree > 99%) greatly enhances the film material's properties in terms of bending, wrapping, stain resistance, and durability Performance in areas such as scratch resistance, yellowing resistance, corrosion resistance, anti-aging, anti-fingerprint, anti-graffiti, and scratch repair. PETG film is produced by processing PETG material, which is obtained through copolymerization modification of PET;

Additionally, the scarcity of EB curing equipment allows your products to stand out from industry competition and maintain a leading position for at least 2 years. (Recommendation reasons: Scarcity of EB curing equipment: Zhihua EB curing equipment: using world-leading imported American EB electron beam curing equipment, which belongs to civilian non-power nuclear technology equipment. After purchase, the equipment needs to undergo review and approval by relevant government departments in both China and the United States for more than 2 years before it can be delivered to the factory for use.)

What is the history and origin of EB curing technology

Development history of EB electron beam curing technology: ① Originating in the 1960s, it was first applied by Ford Motor Company for surface coating and curing of automotive instrument panels and wheel hubs; ② Consolidated in the 1970s, it was widely applied by American military aerospace enterprises (Boeing/Lockheed), the U.S. Department of Energy, Oak Ridge Laboratory, etc. in aerospace, aircraft, and other components. (For example: the lifespan of the supersonic fighter's radar cover coating cured by EB electron beam was increased from 2 months to 2 years; ） ③. It developed rapidly in the 1980s and was adopted by Tetra Pak, the world's largest packaging company, for use in the food packaging industry, where strict requirements for safety, non-toxicity, and odorlessness are imposed. (Today, EB (electron beam) curing technology is used in the packaging of milk, milk powder, pharmaceuticals, and other products.) ④ In 2021, Zhihua Group entered the home furnishing industry and took the lead in applying EB electron beam curing technology to the surface of wardrobe and cabinet door panels, launching the "Zhihua EB Four-Resistant Board", which greatly enhances the performance of customized home furnishing board surfaces in terms of resistance to yellowing, scratching, anti-aging, corrosion resistance, and anti-fingerprint. In 2023, Zhihua Group continued to upgrade its research and development as well as manufacturing equipment, applying EB (electron beam) curing technology to the surface of decorative film materials. This not only retained the unique performance advantages of the film materials, such as adhesion, coating ability, and small batch color differences, but also completely solved some technical problems of the film materials, such as bending and cracking issues. At the same time, it greatly improved the performance of the film material surface in terms of resistance to yellowing, scratching, anti-aging, corrosion resistance, graffiti resistance, and anti-fingerprint properties.

What is the EB four-resistant electron beam curing process?

EB Four-Resistance Electron Beam Curing Process belongs to: a new type of surface coating electron beam curing process technology for civil non-power nuclear technology; EB/Electron Beam Curing Principle: At the microscopic level, all atoms consist of a positively charged nucleus surrounded by several negatively charged elementary particles, electrons. The electrons generated by the cathode in an electron gun are accelerated to high speeds under the influence of a high-voltage accelerating electric field between the cathode and anode, forming a dense high-speed electron stream (also known as an electron beam EB). When a high-energy electron beam interacts with a coating, it can trigger the coating polymer to quickly transform into a cross-linked solid structure (curing degree > 99%) in a matter of seconds or even less.
