What is timeliness?

Question 1: What is timeliness? Yingshi is an inorganic mineral, mainly composed of silicon dioxide, and often contains a small amount of impurities such as Al2O3, CaO and MgO. It is a translucent or opaque crystal, generally milky white and hard in texture. Timely is a mineral resource with very stable physical and chemical properties. Its crystals belong to ternary oxide minerals, that is, low temperature response time (a- response time), which is the most widely distributed mineral in response time minerals. Generalized response time also includes high temperature response time (b- response time). Timely block, also known as silica, is mainly the raw material for producing quartz sand, as well as the raw material for timely refractory and ferrosilicon firing. Seasonal shyθng [Shi Ying] is a mineral composed of silica, with translucent or opaque crystals, generally milky white and hard texture. The chemical formula of Yingshi is SiO2, and the main component of natural quartz stone is Yingshi, which often contains a small amount of impurities such as Al2O3, IMO, CaO and MgO. It has many types. Seasonal, quartz sand, quartzite, sandstone, silica, opal, diatomite, etc. As a raw material for daily-use ceramics, rice husk ash is also rich in silica. The appearance is usually colorless, white, milky white, gray and translucent, and its Mohs hardness is 7. The broken mask is glass luster or fat luster, and its specific gravity varies with different crystal forms, ranging from 2.22 to 2.65. Like ordinary sand and crystal, it is a substance that "comes out of the womb". When the silicon dioxide crystal is perfect, it is a crystal; Silica becomes agate after gelatinization and dehydration; Water-containing silica gel becomes opal after solidification; When the particle size of silica is less than several microns, chalcedony, flint and secondary quartzite are formed. It is a non-plastic raw material, and the mullite crystal generated by it and clay at high temperature gives porcelain high mechanical strength and chemical stability, and can increase the translucency of the blank, so it is a good raw material for preparing white glaze. During the Republic of China, Shi Jing Sanbao shed was mostly used for production. After the founding of New China, it was widely used in Xing Zi, Duchang, Xiushui and other places, especially after 2000, the usage increased sharply. The dosage of glaze is 10%-30%. Before use, it should be cleaned and sorted to remove dirt and impurities, and then calcined in a kiln at high temperature to facilitate crushing. A colorless and transparent seasonality is called "Krystallos" by the Greeks, which means "Bai Bing". They are sure that it is solid and durable ice in time. Ancient people in China believed that cold crystals in their mouths could quench their thirst. Timely is one of the most widely distributed minerals on the earth's surface and has a wide range of uses. As early as the Stone Age, people used it to make simple production tools such as stone axes and arrows to hunt food and fight against the enemy. Piezoelectric clock is used as the standard frequency of quartz clock and electronic equipment. The glass made after melting can be used to make optical instruments, glasses, glass tubes and other products; It can also be used as industrial raw materials for bearings, grinding materials, glass ceramics and other precision instruments. When crystals contain tiny bubbles or liquids to fill cracks, they will produce rainbows by interfering with light.

Question 2: What does a quartz watch mean? Quartz watches are mainly divided into mechanical watches and quartz watches. Quartz watches are in English. It is a modern invention to apply timely crystal to clocks and watches. The first quartz watch first appeared in 1969. This year, Seiko Corporation of Japan discovered how to make a tuning fork out of time. The working principle of quartz watch is like a tuning fork vibrating according to a certain law. When the crystal is affected by battery power, it will also vibrate regularly. The crystal vibrates as high as 32,768 times per second. We can design a simple circuit to calculate its vibration times. When it counts to 32,768 times, the circuit will send a message to let the second hand go forward for one second. Because the timely vibration is quite regular, the error rate of a day will not exceed 1 second even for a cheap quartz watch. The application of mass production of timely crystal enables watches to be mass-produced, which not only makes the production speed much faster than before, but also reduces the price. About 500 million watches can be manufactured every year, which is enough for global use. Quartz watch can also be called "crystal vibrating electronic watch" because it uses the "vibration phenomenon" of crystal piece. When the crystal is subjected to an externally applied voltage, it will deform and expand. On the contrary, if the crystal is compressed, a current will be generated across the crystal. This property can also be seen in many crystals, which is the so-called "piezoelectric effect". Quartz watch is a crystal that vibrates periodically and continuously, which brings us accurate time. First of all, the crystal in the quartz watch will vibrate correctly at the frequency of 32768Hz when it is energized. Then this frequency must be converted into a signal current period of 1Hz (the current changes once every second). Increase the amplitude of some signals (because the current generated by vibration is very weak), and then start the rotor gear with some signal current, and the second hand on the watch will start accordingly. After that, the minute hand and the hour hand are all related to the principle of mechanical structure. For example, the second hand jumps 60 times and the minute hand jumps. All quartz watches are equipped with batteries. It provides energy for an integrated circuit and a quartz resonator, and vibrates 327678 times per second. There is something faster than this. The integrated circuit is the "brain" of the watch. It controls the vibration of the quartz resonator and acts as a frequency divider. 32,768 vibrations divided by 65,438+05 vibrations produce a pulse per second. With the "raw material" for one second, you can drive the display.

Question 3: What does a quartz watch mean? Battery is timely, but mechanical battery is not timely.

Question 4: What does a quartz watch mean? The timely electronic clock is referred to as the timely clock, including quartz watches and quartz clocks.

There are three kinds of clocks and watches: pointer, digital and dual display.

The electronic watch takes the battery as the energy source, the oscillator as the time reference, the integrated circuit as the core, and displays the time by hands or numbers.

In terms of composition, the pointer quartz watch is the same as the pointer quartz clock, and the digital quartz watch is the same as the digital quartz clock, but the pointer clock is different from the digital clock. ① Basic composition of pointer and digital quartz watch (see figure). Pointer quartz watch is also called analog quartz watch. The pointer dial of a traditional mechanical watch. According to the need, it can be made into three stitches or two stitches, and a single calendar or a double calendar can be attached. This is a popular quartz watch. Digital quartz watches use numbers instead of hands to display time. There are two display modes. One is light-emitting diode display (LED), which is no longer used because of its high power consumption; The other is liquid crystal display (LCD), which is adopted by most digital quartz watches. It has the advantages of low power consumption, simple structure and low cost. However, liquid crystal displays emit light passively. In the dark, numbers can only be seen by lighting inside the table, and the LCD has a small viewing angle. Dual-display quartz watch combines the advantages of the above two quartz watches. It not only has the pointer of pointer quartz watch, but also has digital display, which is fully functional.

The characteristics of analog and digital quartz watches are: both energy sources are batteries, usually silver oxide batteries or mercury batteries; The time reference adopts a timely oscillator with a frequency of 32768Hz. In order to obtain the basic units of time-seconds, minutes and hours from this frequency, medium and large complementary metal oxide semiconductor integrated circuits, namely CMOS integrated circuits, are adopted. The biggest difference between the two watches is that in the pointer quartz watch, in order to convert the electrical signal into the rotation of the pointer to indicate the time, a micro stepping motor and a gear transmission system are used as transducers; Digital quartz watch adopts digital liquid crystal display device, and the corresponding control circuit and booster circuit are set in the circuit.

Question 5: What is a response board? It is a flaky product with ultra-high wear resistance, acid and alkali resistance, aging resistance, corrosion resistance, high insulation, waterproof and anti-slip properties, which is vulcanized by seasonal fine powder (silicon micro powder) through a special process.

The characteristics of the timely plate:

1, acid and alkali resistance, grease resistance, wear resistance, high and low temperature resistance and ozone aging resistance;

2, scratch resistance, easy scrubbing, corrosion resistance, tear resistance, impact resistance and thermal shock resistance;

3. Excellent insulation performance;

Excellent optical performance, low refractive index and high reflectivity; 5, anti-ultraviolet, waterproof, moisture-proof, non-slip;

Question 6: What do you do in time? Due to the difference in particle size, color and inclusion, there are many varieties in time. Colorless and transparent crystal, purple crystal is commonly known as amethyst, smoky yellow, smoky brown to nearly black is commonly known as tea crystal, smoky crystal or ink crystal, and rose red is commonly known as hibiscus stone; The kidney-shaped bell-shaped Geng Jing is called the sarcophagus, and the crystal glands with concentric bands of different colors are called agates. There are obvious liquid inclusions in agate crystal glands, commonly known as agate water sacs, and the gray-black aphanitic composed of fine crystals is called flint in time, commonly known as flint. Timely has many uses. Crystal single crystals without cracks and defects are used as piezoelectric materials to manufacture quartz resonators and filters. Generally, timely can be used as raw materials for glass, and purple and pink timely and agate can also be used as raw materials for carving handicrafts. Yingshi is one of the most important rock-forming minerals, widely distributed in igneous rocks, sedimentary rocks and metamorphic rocks. Brazil is a world-famous crystal producer. Crystal crystals with a diameter of 2.5 meters, a height of 5 meters and a weight of more than 40 tons have been found.

Question 7: What is timeliness and what does it do? It should be silicon dioxide, and its chemical composition is SiO2.

Time is divided into low temperature time and high temperature time. At low temperature, the strain often produces hexagonal columnar crystals with spires, and the cylinders have transverse stripes. The spire, which is similar to a hexagonal bipyramid, is actually composed of two rhombic simplex. The response body is usually granular, massive or crystal cluster-like, crystal gland-like, etc. Pure aging is colorless and transparent, glassy, oily, conchoidal fracture shiny, cleavage-free, Mohs hardness 7, specific gravity 2.65. Pressure or heat will produce an electrical effect.

Colorless and transparent crystal, purple crystal is commonly known as amethyst, smoky yellow, smoky brown to nearly black is commonly known as tea crystal, smoky crystal or ink crystal, and rose red is commonly known as hibiscus stone; Kidney-shaped, bell-shaped aphanitic is called chalcedony, and crystal glands with concentric bands of different colors are called agate. There are obvious liquid inclusions in the gland of agate crystal, commonly known as agate water sac. The gray-black aphanitic composed of fine crystals is called flint in time, commonly known as fire time (b- time).

Timely has many uses. Crystal single crystals without cracks and defects are used as piezoelectric materials to manufacture quartz resonators and filters. Generally, timely can be used as raw materials for glass, and purple and pink timely and agate can also be used as raw materials for carving handicrafts.

Question 8: What does a quartz watch mean? It was originally called an electronic watch.

Quartz watch is made by using the principle that the timely crystal is driven by electricity to produce regular vibration. Compared with traditional mechanical watches, quartz watches are lighter and more accurate, and at the same time, they avoid the cumbersome winding of mechanical watches, so they are very popular.

Cheaper and more accurate than mechanical watches.

Question 9: What is the material of quartz stone? Timely is a mineral resource with very stable physical and chemical properties. Quartz stone is the abbreviation of the plate produced by quartz stone plate manufacturers at present, so it is called quartz stone because its main component content is as high as 93% in time. In the process of magmatic intrusion and evolution, due to the changes of temperature and pressure, the hydrothermal solution rich in SiO2 _ 2 differentiated, and the bedding and cracks infiltrated into the metamorphic rock series of pre-magmatic rocks, or invaded along the contact fracture zone of pre-magmatic rocks, forming vein-like Shi Ying ore bodies. Quartz rocks are classified into powder quartz, green quartz, Bai Shiying quartz and yellow quartz. Quartz stone can be divided into ordinary quartz sand, refined quartz sand, high-purity quartz sand, fused quartz sand and silicon micropowder. The main material of quartz stone is timely, and the rich TINT makes it have the texture of natural stone and beautiful surface luster. Quartz stone countertops have various colors, and Gobi series, crystal series, granite series and shining star series are more distinctive. They can be widely used in public buildings (hotels, restaurants, banks, hospitals, exhibitions, laboratories, etc. ) and home decoration (kitchen countertops, washstands, kitchen walls, dining tables, coffee tables, window sills, door covers, etc.). This is a kind of non-radioactive pollution. It should be pointed out that the quality of quartz stone is directly related to the content of resin. The higher the timely content in quartz stone, the lower the resin content, the better the quality, the closer it is to nature, and the less prone to deformation. Experts pointed out that when the resin content in quartz stone is greater than 10%, its corresponding technical indicators will be reduced, and quartz stone at this time can no longer be called real quartz stone.
