Electronic anti-fog mirror

2.1 Mirror performance The preferred silver mirror is used as the substrate to ensure that the mirror surface is bright and soft, and the image is clear and vivid. The mirror is further processed according to different requirements, making it both decorative and practical.

2.2 Anti-fog function In the usually foggy bathroom or other environment, the mirror generates heat after the anti-fog mirror is energized for about 10 minutes. The mirror surface prevents moisture from condensing on the mirror surface in the heat-effective area, ensuring the mirror surface is clear and bright.

2.3 Electrical performance 50Hz AC, mirror temperature constant at normal room temperature is close to 35*2 body temperature, which can prevent burns on the skin and cause mirror rupture. The electric heating film uses a thin insulating spacer to prevent leakage and moisture intrusion, and the heating device is protected by waterproof, corrosion-resistant PVC or other insulation. The electrical safety performance complies with the relevant provisions of GB4706.1-1992 "General requirements for safety of household and similar electrical appliances".

2.4 Easy installation With a new installation method such as hanging or hanging type, you only need to nail 1~2 steel nails on the wall to hang the mirror. It eliminates the cumbersome, fragile and even professional installation problems commonly used in ordinary mirrors.

3 Introduction to Production Process The process of anti-fog mirror production generally has the following two types: (1) Fufa glass silver mirror cutting ※ edging, sandblasting, silk screen printing, engraving, coating ※ assembling electric film and accessories ※ inspection packaging factory (2) (2) Fufa glass cutting ※ edging, sandblasting, silk screen printing, engraving, coating ※ tempering ※ silver mirror ※ assembly of electric heating film and accessories ※ inspection, packaging factory 3.1 mirror processing mirror is the main component of anti-fog mirror Its processing quality and effect are important guarantees for the high quality of anti-fog mirrors.

First of all, the lens should be made of high-quality, preferably float glass, high-reflectivity, corrosion-resistant silver mirror first-class products, to avoid the use of poor performance, easy to oxidize aluminum mirror. The thickness of the silver mirror can be selected from 4mm, 5mm or 6mm. The most commonly used is the 5mm silver mirror. If the anti-fog mirror has a large single-chip area (greater than 1m2), consider a 6mm silver mirror or a tempered mirror to ensure a certain strength and Installation reliability.

If the anti-fog mirror adopts the frame-mounted installation method, it can be directly cut with a large silver mirror, but the processing of the anti-fog mirror lens usually needs to be processed by the edge of the car (edging).

The side of the mirror is divided into straight chamfers, C-shaped sides and oblique sides, etc. The oblique sides are divided into single oblique sides, double oblique sides and lotus leaves, and have different edge decorative effects. The lens behind the car can save the installation method of the frame, which is more convenient and convenient.

3.2 The choice of anti-fog parts is to make the mirror more practical and ideal anti-fog effect. The choice of anti-fog method is very necessary. At present, there are two main types of methods: chemical method and heating mirror method.

The chemical method is to treat the surface of the mirror with special chemical agents. The role of these chemicals is to reduce the surface tension of the mirror surface, so that the water droplets condensed on the mirror surface are spread out without forming water droplets, thereby preventing fogging. The law cannot be done once and for all, and it needs to be repeated, especially after cleaning the mirror.

The heating method is a commonly used method for the anti-fog mirror to achieve the anti-fog function. The method has the advantages of simple operation, obvious anti-fog effect and low cost. The heating method is divided into an electric heating film method, a mirror-plated colorless conductive film method and other heating mirror methods. At present, the anti-fog mirrors commonly used on the market all adopt the mirror back electric heating film method.

The selection of electric heating film needs to be highly valued. At present, the electric heating film available in Europe, America, Taiwan, Sino-foreign joint venture and domestic products have their own advantages. However, while considering the price factor, the electric heating film has the following properties. Conditions: (1) Electrical performance The electrical performance of the electric heating film must meet the requirements specified in the relevant provisions of GB4706.1-1992 "General requirements for safety of household and similar electrical appliances", and the test report of the national authoritative inspection department is required to ensure its electrical Safety performance and reliability of use.

(2) The rated voltage is 220V AC. Some foreign or Taiwanese products have AC 110V and other rated voltage values. These products cannot be used.

(3) It must be thin, so it is easy to mount. If self-adhesive type is adopted, it is better to have a self-adhesive form, and the lead wire of the electric heating film needs to have certain tensile properties.

(4) Size of electric heating film Generally, the anti-fog area of ​​the anti-fog mirror accounts for more than 50% of the total area of ​​the mirror. Depending on the size of the anti-fog mirror, the electric heating film should be available in various specifications, and multiple electric heating films should be conveniently connected in parallel. Stitching to suit the needs of shaped or oversized products.

(5) The temperature control is selected so that the mirror surface can reach the constant temperature of 35 * C after 10 minutes of energization. The selection of the temperature control is also very necessary. Generally, a small electronic temperature control device can be considered. The device should be compact and ideally installed. The mirror back does not protrude from the mirror to cause damage, and it requires a long service life. There are also measures to achieve a temperature saturation thermostat after mirror cooling using a diode shunt method to achieve the goal.

3.3 Other decorative and functional accessories In order to improve the decorative and practicality of anti-fog mirrors, some ideal accessories have emerged, such as wall hangings, supporting parts, copper buckles, storage platforms, lighting, small concave magnifying glasses and various frames. Etc., these accessories can be selected according to the different taste needs of different customers.

Wall-mounting parts, supporting parts and copper buckles are designed to facilitate the installation of anti-fog mirrors. They are designed with reference to the accessories of some new mirror products from abroad. The simple installation method and ideal decorative effect are very suitable for the use of anti-fog mirror products. The storage platform has a tempered glass platform and an acrylic platform, etc. It is a functional and highly assembled accessory, and a mirror light, a small concave magnifying glass, etc., which fully considers the needs of the user and achieves care to the user.
