Face Shield

Core functions and protection mechanism of protective face shield

The basic function of protective face shield is to provide the operator with a transparent, solid, and fully covered facial protection barrier. Its core functions mainly include the following aspects:
Impact resistance and splash resistance: Industrial sites often have high-speed splashing metal chips, stones, wood chips, abrasive debris and other solid particles, which pose a serious threat to the face during high-speed cutting, grinding, milling, sandblasting and other processes. Greateagle protective face shield is made of high-strength polycarbonate (PC) or composite PVC material, with excellent impact resistance, which can effectively resist the impact of particles and prevent facial scratches or eye penetration injuries.
Anti-chemical corrosion and liquid invasion: In the chemical, pharmaceutical, cleaning, electroplating and other industries, workers often need to face dangerous chemicals such as acid and alkali liquids, organic solvents, and corrosive gases. The protective face shield is coated with an anti-corrosion coating on the surface of the material to prevent droplets from splashing onto the skin or eyes, avoiding skin burns and chemical reaction allergies, while effectively reducing the health risks caused by long-term exposure.
Protection against thermal radiation and high-temperature burns: In high-temperature operations (such as smelting, welding, pouring, and heat treatment), there are not only splashing metal liquid and sparks, but also high-intensity thermal radiation and infrared irradiation. Some models provided by Greateagle are equipped with heat-resistant screens with light-shielding coatings or metal coatings, which can effectively reflect heat energy, protect the face from burns, and maintain good visual clarity.
Maintain a wide and clear field of vision: Compared with goggles, protective face shields can provide a wider field of vision to avoid misjudgment caused by "visual blind spots". The surface of Greateagle Safety Products(Ningbo) Co., Ltd.'s transparent face shields is anti-fog, anti-scratch, and multi-layer optically treated, which can maintain clear vision in high humidity or large temperature changes, improving operation accuracy and work efficiency.

Material and process advantages of Greateagle protective face shields

Greateagle Safety Products(Ningbo) Co., Ltd. has always focused on material innovation and product durability as the research and development focus. Its core components of face shields have the following advantages in terms of materials and processes:
PC materials have an impact strength close to that of steel, but are much lighter than glass or metal, and are widely used in explosion-proof transparent equipment. Greateagle uses high-purity optical-grade PC raw materials to ensure protection strength while providing excellent light transmittance and flexibility. It is not easy to break even in the case of falling or impact, which prolongs the service life.
For users facing chemical liquids or highly corrosive environments, PVC face shields provide stronger chemical resistance. After special formula treatment, Greateagle PVC protective face shields can remain transparent, non-deformed, and non-brittle after contact with a variety of chemical reagents. It is an essential protective equipment for chemical workshops and laboratories.
In order to improve the performance of the product in complex environments, some of Greateagle Safety Products(Ningbo) Co., Ltd.'s high-end protective face shields have specially added multiple functional coatings on the surface of the transparent screen to enhance durability and operating experience. Among them, the anti-scratch coating can significantly reduce scratches caused by frequent wiping or particle friction, and extend the clear life of the face screen; the anti-fog coating effectively prevents the mirror from fogging caused by the wearer's breathing, ensuring a clear field of vision in working environments with high humidity or large temperature differences; the anti-static coating can prevent dust in the air from adhering to the mirror surface, and is suitable for clean rooms, electronic factories and other places with high cleanliness requirements; in addition, the mirror coating layer is suitable for mining, construction and other working environments with strong sunlight or strong light, with good anti-glare effect, reducing the impact of strong light stimulation on the eyes, and improving visual comfort and working safety. The integration of these functional coatings enables the Greateagle face screen to provide excellent visual and protection experience under various working conditions.

Structural design and ergonomic optimization

On the basis of ensuring the protection effect, Greateagle also pays great attention to wearing comfort and structural adaptability. Its face shield system mostly adopts modular design, which is convenient for replacing the mask body, headband or forehead protector, and provides adjustable solutions for different user head shapes:
Full-face protection structure: covers the entire face and chin area, provides more complete protection, and prevents splashes from invading from below or from the side. It is often used in metal processing and welding industries.
Flip-up structure design
Equipped with a movable bearing structure, the wearer can flip up the mask for observation or ventilation in a non-operating state, avoiding the inconvenience caused by frequent removal and wearing, and improving the continuity of on-site operations.
Adjustable head-mounted system
Adopting a knob-type or slide-type headband structure, users can quickly adjust the tightness according to the head circumference, and wear it firmly without slipping. Some models are also equipped with a decompression sponge pad to effectively relieve the discomfort and indentation caused by long-term wearing.
