Introduction of fixed Rfid Reader Writer

2021-03-29 15:05:33 | 不老長寿

Fixed Rfid Reader Writer are generally equipped with 1-8 antenna ports, and the number of antennas depends on the coverage required by the RFID application. Some applications, such as file input and output, require only a small coverage area, so one antenna can do the job well. Other applications with larger coverage areas usually require multiple antennas to create the necessary coverage.
The fixed Rfid Reader Writer only needs to be fixed in a certain place and kept powered on, and it will continue to collect data. Therefore, if you want to collect how many goods are in the warehouse in a day, but don't want to manually scan every time you purchase, then using a fixed Rfid Reader Writer is a good way to automate the process. Fixed Rfid Reader Writers generally have a larger reading range than handheld Rfid Reader Writer, and can monitor a larger area at a time.

 

Can all stones be used as eco-friendly bags? Stone paper bags

2021-03-26 22:31:50 | 不老長寿
 

The types of bags we use in daily life include plastic bags, cloth bags, paper bags, etc., and the manifestations of plastic bags are also ever-changing. However, with the increasing pressure of white pollution on the environment, the failure to provide plastic bags has corresponding inconvenience to our daily shopping. The production of environmentally friendly bags has attracted attention!
The new material PCC high-energy masterbatch made by Shenzhen Shineng Paper Co., Ltd. through technical processing and refining of a stone can not only produce products that replace plastics, but is basically the same as petroleum-based plastic products in appearance. While being environmentally friendly, it greatly reduces the production costs of plastic products companies. The environmental protection bag-Stone Paper Bags produced by PCC high-energy masterbatch has been promoted in many large supermarkets.

The PCC high-energy masterbatch developed from this kind of stone can be directly degraded by thermal oxygen, and directly turned into calcium carbonate after incineration. It can also be decomposed naturally under natural light conditions. Unlike plastic products, it is difficult to be naturally degraded. It is burned. Sometimes it will pollute the atmosphere and leave coking.

Understand the correct use of PVC electrical tape.

2021-03-25 17:27:08 | 不老長寿

1. Starting point for wrapping PVC electrical tape

The starting point of PVC electrical tape is very important. If the starting point of PVC electrical tape is not well selected, it will not only waste electrical tape, but may also affect the final effect of electrical tape. Generally speaking, the wrapping starting point of PVC electrical tape should be 1-2 cm of the wrapping position where the copper wire or aluminum wire is exposed on the line.

2. Surrounding method of PVC electrical tape

Different line joints have different PVC electrical tape surrounding effect methods. According to the wiring method, the surrounding methods of PVC electrical tape include "ten" surrounding connection, "one" surrounding connection, "D" surrounding connection, etc. . Therefore, you must pay attention to the corresponding wrapping method before wrapping the PVC electrical tape.

3. Perform the wrapping operation correctly according to the wrapping method of PVC electrical tape

After understanding the wrapping starting point and wrapping method of PVC electrical tape, electricians can perform wrapping operations. In the wrapping process, they must follow the correct wrapping method.

Take the "one" line connector as an example. When using PVC tape, after ensuring that the beginning of the PVC tape is flat, surround the past from the interspersed end of the wiring diagram to the other end, and try to force the PVC electrical tape to wrap around the line as hard as possible. On the way. Ensure that the PVC electrical tape will not loosen or loosen during the effective period after use.

4. Precautions when wrapping PVC electrical tape

PVC electrical tape cannot directly affect the line joints when it is surrounded. PVC electrical tape is generally used together with electrical insulating black tape. Generally, when wrapping, first use electrical insulating black tape to wrap 2-3 layers on the wire head, and then use PVC electrical tape to wrap 2-3 layers again, and repeat the loop twice to complete the wrapping operation. At the same time, the strength of the surrounding should be maintained as much as possible during the surrounding process, so as to ensure that the PVC electrical tape will not spread, peel off and other phenomena.

 

What are the characteristics of black sesame oil and how to distinguish true from false?

2021-03-25 15:19:19 | 不老長寿

Sesame has been used for oil production in China for more than 1,000 years. Black sesame oil is deeply loved by consumers for its rich nutrition and unique flavor.
In ancient China, sesame was also called "flax" and "seed oil", so people called sesame oil "flax oil" or "seed oil". In Japan and Korea, people also called it "flax oil", among which black sesame oil Also called confinement oil.
According to modern nutritional analysis, black sesame contains a variety of nutrients needed by humans, and its protein content is more than that of meat. Among them, the content of amino acids is very rich, the calcium content is much higher than that of milk and eggs, and it also contains vitamins A, D and rich B. Vitamins.
Black sesame seeds contain a large amount of lecithin, which is a nutrient element that can prevent the hair from turning white or falling out prematurely.
Black sesame oil contains sesame oil, so it has a unique aroma. Due to the high content of vitamin E, it has anti-oxidant effect, and regular consumption can scavenge free radicals and delay aging.
There are several types of black sesame sesame oil to distinguish true and false:
1. Color: pure black sesame sesame oil is amber, slightly yellowish reddish, yellowish when mixed with rapeseed oil, and reddish when mixed with cottonseed oil.
2. Water test method: Dip a drop of black sesame oil into a large bowl of warm water with chopsticks. The pure black sesame oil will appear thin and transparent big oil flowers, and the adulterated ones will be small and thick and not easy to spread.
3. Smell: pure black sesame oil has a mellow and unique smell, while adding peanut oil and soybean oil will have a faint fishy smell. Fragrance oils with artificial flavors have a poor sense of smell.
4. Look at the price: you get what you pay for, and more than 2 catties of black sesame raw materials produce 1 catty of sesame oil, so real black sesame oil is naturally expensive, and too cheap is definitely not pure.
