According to the content of the notification, at the end of 2018, the General Administration of Market Supervision organized a national supervision and spot check on the quality of 30 kinds of products such as food processing machinery (juice extractor, juice machine), dehumidifier and vacuum cleaner.
This time, a total of 2,788 batches of products produced by 2,478 companies (not involving export products) were sampled, and 349 batches were found to be unqualified, and the unqualified discovery rate was 12.5%. Among them, the inspection found that the unqualified discovery rate of 10 kinds of products such as dehumidifier, isolation switch and power transformer is between 10% and 20%.
Dehumidifiers also have a certain relationship with industrial production in China. According to different uses, dehumidifiers can be divided into domestic and industrial use, industrial dehumidifiers account for a large proportion, and are used in China's food, medicine and other fields.
In the pharmaceutical industry, if the drug is in a humid environment, it is easy to get wet with mold or various bacteria, affecting the quality of the product. If the company does not pay attention to it, let these drugs flow into the market, it may affect the patient's drug effect and health. And the patient has a negative impact. The dehumidifier can reduce the humidity, make the space dry, and ensure the environmental safety of the drug.
According to the industry, with the increasing attention of food safety issues in recent years, the requirements for the production, packaging, transportation and storage of pharmaceuticals are increasing. The role of the dehumidifier is becoming more and more prominent, and qualified products can meet the dehumidification needs of enterprises.
In view of the specific situation of the dehumidifier inspection, the Municipal Supervision Bureau randomly selected 30 batches of dehumidifier products produced by 29 enterprises in 6 provinces (autonomous regions and municipalities), of which 5 batches of products were unqualified, and the rate of unqualified discovery was 16.7%.
The project focused on 19 items including moisture resistance, protection against live parts, leakage current and electrical strength, internal wiring, structure, nominal dehumidification, continuous disturbance voltage, and continuous disturbance power. Unqualified items involve structures, protection against live parts, internal wiring, and continuous disturbance voltage.
Data show that in 2017, China's dehumidifier market sales of 1.49 million units, retail sales of 1.96 billion yuan. In the first half of 2018, the dehumidifier retail scale was 1.12 billion yuan, a year-on-year increase of 7.9%. In general, the dehumidifier market has maintained a growing trend. In this context, the competition between domestic dehumidifiers and imported dehumidifiers, as well as competition between similar products, has become increasingly fierce.
The * in the field pointed out that foreign dehumidifiers have mature technology and mature market share, and the domestic dehumidifiers are more and more abundant in recent years, but the penetration rate is still relatively low, and many enterprises dehumidify domestically. Machine awareness is not enough, so competitiveness still needs to be improved.
However, in general, with the continuous expansion of dehumidification demand in China's pharmaceutical, food and other industries, the future development potential of the domestic dehumidifier product market is still huge. While taking advantage of opportunities, domestic dehumidifier manufacturers must also pay attention to product quality, improve process technology, enhance the optimization of structure design, and provide product safety design, such as high quality, high safety and high efficiency. The dehumidifier products with value help the domestic dehumidifier industry to enter a new stage and promote the more stable development of the pharmaceutical and food industries.
Variable Attenuator
CNI provides 3 kinds of variable attenuators for different application.The circular variable attenuator can make the optical density linearly varies around a 0°-270° circle for measuring Laser energy farthest. As for the square one, the optical density linearly varies across the length for measuring laser energy. Also the high power variable attenuator is available for customization.
