Many people think that dental implantation is the end of dental treatment, as long as the dental implantation is successful, it will be done once and for all, and will never suffer from toothache. I hereby reminds the public that this statement is wrong. Although dental implants are not threatened by tooth decay, like real teeth, dental implants may loosen due to damage to surrounding tissues. Improper cleaning of teeth will accumulate plaque at the junction between the implant and the gums, causing inflammation and shrinkage of the soft tissue around the implant, forming a pocket, further destroying the alveolar bone around the implant, causing the foundation around the implant to collapse, and finally The implant will loosen and fall off. 1. Keep your mouth clean If you want to extend the useful life of dental implants, good oral hygiene is very important. Xiaoya reminds that using a toothbrush alone is not enough, but also needs to be combined with dental floss and interdent

  The high temperature resistance furnace is a national standard energy-saving cycle electric furnace, mainly used for heat treatment of alloy steel products, various metal parts, normalizing, quenching, annealing, etc., or high diamond cutting blades. How much can the temperature of the high-temperature resistance furnace be lowered to open the furnace door?     First of all, considering the life of the heating element and the furnace and avoiding rapid cooling of the furnace, it is recommended not to open the furnace door when the temperature is too high.     In addition, the heating speed of the high-temperature resistance furnace is limited. It is recommended that it be lower than the rated value and not too high, otherwise the temperature of the program will rise rapidly, and the difference between the actual temperature and the actual temperature will increase, and the electric furnace will automatically increase the thermal current, which will cause The current is too high

As the name implies, the large-diameter bellows hose is larger than the ordinary type of bellows hose. The larger diameter of the bellows hose has different functional characteristics. The manufacturer produces and processes the product according to customer needs. This article is You elaborated on the main features of this product. 　　 Features of large-diameter bellows hose: 1. The bending radius should not be less than the given bending radius to prevent damage to the bellows hose skeleton or early damage due to excessive stretching. 2. According to the conditions of use, choose the correct type and specifications of the bellows hose, and do not misuse or substitute. 3. When using the bellows hose, the pressure should be adjusted slowly and evenly to avoid the sudden pressure increase and damage to the pipe body. 4. When the working place changes, it should be carried away from the ground, not to drag the ground, so as to avoid corrosion of the skeleton layer after scratching t

When some people smile, there will be a lot of gum tissue above their upper teeth. This is what we often call "gummy gum", also known as laughing gum. People who are labelled "gum laugh" will feel lack of self-confidence, which will actually inhibit the frequency and even the number of smiles. However, the clinical effect of this smile is getting better and better. What is a cheeky laugh? Medically speaking, when you laugh, your upper lip can't completely cover your teeth, your gums are obviously exposed, and in serious cases, even the gingival sulcus will be exposed, which looks very shameful. Of course, the boundaries are still blurry at first glance, right? Here is a simple and rude explanation: It is not that the gums are exposed even when they are laughed, but the gums are generally exposed as "gummy gums" when the amount of gum exposure is greater than 3 mm when smiling or laughing. 1) Slightly exposed gums: The part of the gums exposed

  That is, organic light emitting diode is a new display technology, it has a wide viewing angle (over 170°), fast response time (one thousandth of LCD), good low temperature performance (normal display at minus 40 degrees), low power consumption Wait. This technology is widely used in car displays, mobile phone displays, etc. With the development of OLED technology, white light OLED has also begun to emerge in the field of lighting, especially in urban lighting, billboards and other industries that have placed high expectations.   In fact, it contains two kinds of small molecule OLED and polymer OLED (also known as PLED). The difference between small molecule OLED and polymer OLED is mainly reflected in the different processes of the device: small molecule devices mainly use vacuum thermal evaporation film forming process, polymerization The physical device adopts spin coating or spray film forming process.    The preparation process of OLED devices generally includes: ITO glass

With the increasing degree of automation in electronics factories, many machines require vacuum as the power of the equipment. Most of the vacuum requirements are around --0.06MPa --0.08MPa.         At present, most of the vacuum generators are used to convert compressed air into vacuum gas. The conversion efficiency is only 50%, which is a waste of electricity. It also increases the maintenance cost of many air compressors.         If you change to a central vacuum system, you can save 50% of energy consumption The composition of the vacuum system:         It is a complete vacuum system composed of vacuum pump , PLC program control system, gas storage tank, vacuum pipeline, vacuum valve, and overseas filter assembly. At present, the system is widely used in electronic semiconductor industry, photoelectric backlight module, mechanical processing and other industries. The system has the following advantages: 1. Reduce noise in the factory. 2. Avoid wasting electrical energy. 3

1) The failure of the trace oxygen analyzer shows that the temperature of the measuring cell is low. You can check the connection of the thermocouple of the measuring cell, check the insurance on the multiplexer board, and check the wiring of the circuit board. 　　 (2) An instrument failure shows that the potential of the measuring cell is high or low. You can check the circuit connection of the measuring cell, check the connection between the circuit boards, and check the zirconia sensor. 　　 (3) The sensor responds slowly to changes in the oxygen content of the sample gas, and the measured value is low. In January 2005, the measurement value of a zirconia trace oxygen analyzer was seriously low, and the sensor response was slow. After checking the sampling system of the instrument, calibrating the zero range, and checking the sensor, it is finally confirmed that the sensor is malfunctioning. After replacing the sensor, the instrument resumes normal measurement. 　　 (4) The i
