Optical sorters are not sorters. It mainly completes the rejection of a few defective products in most normal materials;  ​color sorter   , it cannot be done at one time like rice selection. The color sorter mainly selects the color according to the surface color of the object. There must be a certain color difference between the normal material and the defective material; the smaller the color difference, the more difficult the color selection. The ability of the color sorter is directly related to the quality of the raw materials. Different impurities have a great influence on the performance indicators that the color sorter can achieve. The three indicators have the relationship of mutual influence and restriction. After the machine is debugged normally, improve the sensitivity, the better the color sorting effect, the larger the take-out ratio; the output also directly affects the color-sorting effect and the take-out rate. like: ​What is the purpose of the color sort...

The driver of the LED lamp is selected according to the operating range of the lamp and the related characteristics of voltage and current. If it is a low-power LED lamp, you only need to choose a simple resistive driver when choosing a driver, ​waterproof led driver ，     but if it is a high-power LED lamp, you need to choose a cross-current driver when choosing a driver. In addition, when choosing a driver for an LED lamp, it is also necessary to choose according to the situation of the lamp bead. It depends on whether the drive current matches the current required across the lamp bead. Generally, when purchasing LED lamps, you can also directly purchase the driver. , all match well. like： ​How to choose a drive that matches a previously used drive ​What to Consider When Choosing an LED Driver  ​led waterproof power supply shell structure

What happened to the oil leakage of the electronic cigarette? Excessive smoking is more common when using e-cigarettes.  ​vape manufacturer ，    When using electronic cigarettes, it is best to draw evenly, with appropriate suction, neither too large nor too small. The pods are squeezed, and the pods are usually bitten by the mouth, or squeezed too hard by hand during use, causing oil to leak. Long-term storage and non-use of electronic cigarettes will also lead to oil leakage. The cartridges should not be stored for too long and should be used up within normal time. Refueling too fast or too much will cause the atomizing core to be oversaturated or part of the e-liquid cannot be absorbed by the atomizing core and enter the base, resulting in oil leakage. like： ​How to choose electronic cigarette? ​What should I do if the e-cigarette cartridge leaks oil and eats it? ​Why electronic cigarettes can not smoke the smell of smoke

Quartz glass defects and metal transition impurities of the laser itself, these impurities will affect the optical phenomenon of light in the transmission process, ​laser marking machine  ，    basically we can divide it into absorption loss, scattering loss and dispersion loss. Absorption consumption: The reason for absorption loss is that the core contains metal impurities, and OH absorbs light, mainly absorbing infrared and ultraviolet rays. Dispersion consumption: In the scattering of the laser marking machine, due to the different atomic densities of the different materials being marked, different levels of fluctuations will be caused, and then rapidly agglomerated to form a situation of uneven density. Dispersion consumption: The degree of dispersion is also one of the important factors affecting the laser loss of laser marking machines. Three causes of waveguide dispersion, data dispersion, and intermodal dispersion. The losses caused by these three aspects are diff...

Injection molding process: 1. The mold temperature should not be too high. 2. The barrel temperature should not be too high.  .  ​ plastic injection moulding      ， 3. The injection pressure can be increased appropriately. 4. Properly increase the injection speed. 5. The holding time should be set longer. 6. Properly increase the cooling time. 7.

Guarantee the dry quality of wood. The main indicator of the drying quality of wood is to make the moisture content meet the requirements and within the allowable error range, and the wood can no longer have obvious drying defects after drying, such as cracking, deformation, etc. Adjust the drying process to an optimized benchmark state as much as possible, that is, on the premise of maintaining the drying quality, to make the drying equipment efficient, low energy consumption, and minimal loss of wood reduction. Save manpower, minimize the possibility of human factor error, and reduce labor costs. Improve the safety of drying equipment operation and reduce the occurrence of fire, drying ...

In terms of configuration, the iPhone 7 is not too outdated at present. After all, the iPhone 6 is still strong. Although its A10 chip is not as good as the current flagship chip,  ​wholesale mobile phones  ， it does not feel more backward than some mid-range Android models. In addition, the small screen of the iPhone 7 feels good in the hand, and there is no pressure to operate with one hand. Besides, in terms of games, after a few games with a full battery, it will start to get hot, the brightness will decrease, the frame rate will drop, and the battery will run out after playing for more than an hour. This should be the biggest disadvantage. Overall, it's still worth buying the iPhone 7 at the moment, as long as the price is right. It's good enough when you're not playing big games. like： ​What are the advantages of using an iPhone 7? ​What are the advantages of Huawei mobile phones?    ​Are Huawei phones worth buying? Why?
