The motive force of modern clocks is mechanical force and electric power. A mechanical clock is a timer that uses the energy released by a heavy hammer or spring as the power to drive a series of gears, adjusts the speed of the gear train with the escapement governor, and indicates the time and measures the time with the pointer. Electronic clock is a modern emergence of electric power, liquid crystal display digital and quartz pointer type timer.   Clock glass is also called clock mirror, it is not only convenient for the wearer to read the time at any time, but also to protect the dial and hands. There are many kinds of clock glass materials, respectively sapphire glass, tempered glass, plexiglass three categories   Sapphire glass: The physical and chemical properties of this mirror are very stable, and the hardness is very high. Second only to diamond, it can easily cope with scratching, wear and erosion. But hesitation hardness is too high, toughness is not good, very afraid of falling. But many high-end watches will use this watch mirror!   Plexiglass also has a name called "acrylic glass". The hardness of the mirror of this material is not very good, and it is easier to scratch. But its willfulness is very good, not easy to break. The cost of plexiglass is very low, and many low-end watches generally choose this kind of mirror.   How to identify the material of the watch glass:   First of all, you can tap the mirror to judge the material of the mirror from the sound. Acrylic mirror will make a sound like plastic, judging from the Angle of weight, acrylic mirror is the lightest, sapphire mirror is the heaviest. In addition, the thermal conductivity of sapphire is very good. Therefore, when you touch it with your hand, it will have a cold feeling. Finally, the sapphire mirror is far smoother than the mirror of the other two materials, so if you drop a drop of water on the sapphire mirror, the water drop is not easy to spread on the top, and other materials will scatter into a piece.

The above is the benefit of fingerprint lock with tempered glass panel, if you want to know more, you can come to the factory field visit, to see how our finished products.

Speaking of tempered glass, everyone will not feel very strange, because in ordinary life, we often come into contact with tempered glass, we all know that tempered glass and ordinary glass is different, but you understand that tempered glass will not produce deformation?   First, will tempered glass deform   Generally speaking, the tempered glass will not be deformed, but the uneven temperature in some factories during the production and processing may lead to deformation. Therefore, in the selection of regular glass processing plants with rich experience, the pass rate will be higher, and more attention should be paid to inspection to avoid deformation of tempered glass when qualified products. Tempered glass is ordinary flat glass through physical or chemical methods to produce a permanent compressive stress layer on the surface of the glass, so as to offset the tensile stress that causes the glass to destroy, and its mechanical strength and thermal stability are higher than ordinary flat glass.   Second, is tempered glass safe 1, tempered glass belongs to safety glass. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, usually use chemical or physical methods, the formation of compressive stress on the surface of the glass, the glass to withstand external forces first offset the surface stress, thereby improving the bearing capacity, enhance the glass itself resistance to wind pressure, cold and heat, impact and so on. 2, the strength is several times higher than that of ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, the impact strength is 5 to 10 times that of ordinary glass, and the strength is improved while also improving the safety. The second is the use of safety, the increase of its carrying capacity improves the fragile quality, even if the tempered glass damage is also small pieces without acute Angle, the harm to the human body is greatly reduced. The cold and heat resistance of tempered glass is 2-3 times higher than that of ordinary glass, and it can generally bear the temperature difference of more than 150LC, which has obvious effect on preventing thermal cracking. ① Security. When the glass is destroyed by external forces, the fragments into small obtuse particles similar to honeycomb, reducing the harm to the human body. ② High strength. The impact strength of tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass. ③ Thermal stability. Tempered glass has good thermal stability and can withstand 3 times the temperature difference of ordinary glass. It can withstand temperature difference of 200℃.

Friends who often contact silicone products will find that some silicone products feel softer, and some silicone products are harder, which is often referred to the hardness of silicone products. Silicon pixel products have different requirements for the hardness of rubber and plastic products in different occasions and different use environments. How about the hardness of all kinds of silicone products? What is the difference in hardness of silica gel? What is the hardness standard of silica gel?   For the use of different fields to choose different hardness of silicone products, the conventional low hardness can reach about 10 degrees, or even lower to 3-5 degrees, usually used silicone products conventional hardness between 30 and 70 degrees. It is also the reference hardness of most products, but the hardness of silica gel products of special materials can reach about 80-95 degrees. Another is the ordinary silicone processing technology, that is, solid silicone products processing technology, at present, the entire silicone industry in the solid silicone products processing technology can be achieved lower softness is 10 degrees, higher hardness is 90 degrees, although higher can also be done, but the defective rate is too high, the product is very brittle, the cost is high, and not easy to release. Therefore, the most suitable hardness for the solid process is between 30 degrees and 70 degrees. Silica gel tear resistance changes, the higher the hardness of the product tear resistance will be weaker, especially the right Angle of the product prone to tear fracture phenomenon, the lower the hardness, the better the tear effect, different hardness tear effect is different. Of course, this also depends on the amount of glue in the product, and the silicone scalability and related performance of different amounts of glue are also very different. Deformation caused by a certain telescopic force, telescopic force is an important control index of silica gel material, just related to hardness, different hardness and vulcanization process temperature and pressure have a great impact on the tensile deformation of silica gel material.   Wear resistance and fatigue change, different hardness of products on wear resistance and fatigue are different, the hardness of ordinary silica gel material increases with the increase of the content of white carbon black, and the phenomenon of fatigue reduction after long-term run-in will also occur. Different elasticity, elasticity is one of the important properties of silicone materials, so different hardness of materials have an impact on each different application products, and the difference in hardness changes is too large, may lead to the use of the entire product, and even affect every link of the entire product! Therefore, many customers in the purchase of silicone products did not correctly explain the use of hardness, the hardness of the material requirements are not specified, but the hardness of silicone products can directly affect the use of your entire product, or do not understand the hardness of silicone material friends can first understand the hardness of silicone material and then decide the hardness of it!

Acrylic mirror used for a long time, it is easy to yellow, discoloration. Because acrylic is a kind of organic glass, ultraviolet light, oxygen, moisture and heat are easy to cause oxidation and discoloration of acrylic, this reaction is irreversible, so it is generally polished to solve the problem of yellow acrylic mirror.   Acrylic mirror with what polishing?   1, the polishing of acrylic mirror is mainly in its processing, the polishing method is mainly diamond polishing and flame polishing. The polishing paste is often used in the entire polishing process to promote the polishing effect of the acrylic mirror. There is a big difference between the polishing and grinding of acrylic is that polishing does not change the dimensional accuracy of the workpiece, and the fine lines and spots on the surface of acrylic mirror products are removed, which promotes the surface finish of acrylic mirror products, and also reduces the fog until the mirror luster appears. Polishing paste is added between the polishing wheel and the finished surface.   2, polishing paste is one of the key process materials in the polishing process of acrylic mirror products, with the advantages of fast polishing speed, high finish and long service life, and can change the polishing quality and operating environment. For example, polishing acrylic with rare earth polishing paste, 1min time to complete the work, such as iron oxide polishing paste, it takes 30 to 60min. Rare earth polishing paste because of its unique chemical mechanical action principle brought about by the high polishing efficiency, become a good choice of acrylic mirror products polishing materials.   3. When manually polishing, a fine felt or absorbent cotton ball dipped in polishing paste should be attached to the polishing surface with a pressure of about 5 ~ 10N, and it should move in a near straight line along the processing length at a speed of 100 ~ 120r/min, usually 1 ~ 2mm per second. Be careful not to concentrate too much on a certain part of the polishing, so as to avoid the formation of local friction overheating and processing depression. In addition, pay attention to the polishing paste on the surface of the polishing area should not be too dry, and pay attention to adding lubrication.   However, the polishing technology of acrylic mirror may be a little complicated for ordinary people, and the maintenance of acrylic mirror is still based on daily maintenance.   How to maintain acrylic mirror?   1, waxing, if you want the acrylic mirror to be bright and bright, you can use liquid polishing wax and wipe evenly with a soft cloth to reach the intention.   2, adhesion, if the acrylic mirror is accidentally damaged, you can use methylene chloride adhesive or fast drying agent to follow.   3, clean, acrylic products, if there is no special treatment or increase of hard resistance, the product itself is easy to wear, scratch. Therefore, for the usual dust treatment, you can rinse with a chicken blanket or water, and then wipe with a soft cloth. If the external oil is disposed of, soft detergent can be added with water and wiped with soft cloth.
