China Science & Technology Hardware City, as the nation's largest professional trading market for hardware products, has annual sales of bearings that account for not a small portion of the overall market sales. It is understood that although the bearing is a small accessory in the host, but it is like the heart of power tools, the role can be described as pivotal. The performance of the host product is good or bad, and the quality of the bearing occupies an extremely important place. For this reason, with the improvement of product quality, the demand for branded bearing products becomes more obvious. As the majority of users have more explicit requirements on the reliability and stability of bearings, as well as the promotion of enterprise management concepts and development concepts in each host industry, and pay attention to nurturing their own brand names and brands, the market demands tend to be more outstanding bearing brands and excellent bearing companies. .
With the development of the market, users are increasingly demanding the accuracy, performance, life, and variety of bearing products. They are not satisfied with the requirements of general-purpose bearings and are turning to products with high accuracy, low noise, and long life. demand. "Although the development of the bearing industry has grown, but compared with the world's leading industrial bearing industry, there is still a large gap between the industry, its main performance is the low proportion of high-precision, high-tech content and high value-added bearing products. Reflected in the market That is, our demand for high-quality bearings must be met by imports.†Mr. Li, the bearing salesman of Jindu Market, talked about the lack of bearing industry.
Nowadays, many bearing enterprises have improved the technical level, reliability, and stability of the bearing industry through a series of independent innovation reforms, and in the future sales process, the important main supporting market will still control these In the hands of enterprises, under the influence of foreign trade slowing domestic demand, some of the power tool bearing market will shift to domestic companies, and imported bearings will decline.
It can be said that this year is a year in which the development opportunities and pressures of the bearing industry coexist. Looking at the domestic market, the increase in uncertainties in the economic operation last year has brought new challenges to the bearing industry and also brought new opportunities. China will continue to increase its investment in infrastructure. Bearing-related industries such as steel, automobiles, and home appliances will also face new opportunities for development. At the same time, with the improvement of living standards, the development of the automotive industry will also drive the development of automotive bearings. In the future, the demand for bearings will grow steadily, and the bearing industry will usher in a period of sustained development. Hardware City, many bearing sellers should firmly grasp the current opportunities, relying on the hardware city of this platform's strong radiation, with more complete varieties, better quality, more competitive prices to seize the domestic and foreign markets, and further improve the quality of bearings Market share.

Use the aroma diffuser well to prevent diseases
Since winter, both heating in the north and air conditioning in the South will make the indoor air very dry. Due to the decline of physical function, the elderly have higher requirements for the indoor environment, especially the elderly friends with respiratory diseases are very sensitive to humidity. In this regard, Li Hong, deputy chief physician of the Department of Otolaryngology of the Fourth Affiliated Hospital of China Medical University, suggested that the elderly might as well put an aroma diffuser in the room to humidify the indoor air.
Humidity refers to the content of water vapor in a certain volume of air. The humidity of the elderly's room is generally 30% ~ 50%. In cold areas, because the indoor heating is too hot, the air will be too dry, dehydrating the elderly's nasopharynx, trachea and bronchial mucosa, reducing elasticity, mucus secretion and ciliary movement. At this time, the dust bacteria inhaled into the air cannot be removed as quickly as usual, which is easy to induce and aggravate respiratory diseases. Dry air will also dehydrate skin epidermal cells and reduce sebaceous gland secretion, resulting in rough, wrinkled and even cracking of skin.
Although too dry air will bring many health hazards, if the indoor humidity is too high, more than 50%, it will also cause discomfort. Especially in winter, humidity will accelerate heat conduction, make the air cold and depressing. There are many old people in this environment will feel chest tightness, out of breath, and even induce heart disease. It can be seen that too dry or too wet air is not conducive to health. Different from the temperature, the discomfort of humidity cannot be solved by increasing or decreasing clothes, and manual adjustment must be adopted. The hygrometer can help the elderly to monitor the humidity at home. If the humidity is lower than 30%, it can be solved by putting a wet cloth on the heating, putting a basin of water on the ground, or using an air humidifier; If the indoor humidity is higher than 50%, it is recommended to turn off the humidifier or use dehumidification equipment, such as air conditioner or dehumidifier. Li Hong reminded that the humidifying rod in the humidifier must be cleaned regularly, otherwise it is easy to breed bacteria and fungi. The immunity of the elderly is generally decreased. If they are infected with fungi and suffer from fungal pneumonia, the follow-up treatment will be very troublesome.
The hygrometer can not only test humidity, but also display temperature. According to the national standard basic specification for service quality of elderly care institutions, the heating temperature of the elderly's residence in winter shall not be lower than 18 ℃ and not higher than 28 ℃. Generally speaking, 23 ℃ ~ 26 ℃ is the most comfortable temperature. For the elderly, if the indoor and outdoor temperature difference is too large, it may cause violent vasodilation and contraction, lead to obstacles in cerebral blood circulation, and then induce stroke. Therefore, it is best for the elderly to maintain a temperature difference of 5 ℃ ~ 10 ℃ between the living room and the outdoor in winter.
It should also be reminded that the elderly room should be regularly ventilated. Air flow can reduce the breeding of bacteria, prevent moisture return and prevent colds. It is recommended to ventilate 2 ~ 3 times a day for no less than 30 minutes each time. Direct convection wind shall be avoided during ventilation. Some old people rely on air purifiers. However, the general purifiers on the market can only remove dust, oil fume and peculiar smell, and the more high-grade ones can kill bacteria and viruses. Moreover, the use of Air Purifier in closed space for a long time may cause secondary pollution, so it is not necessary to use it when the air improves, and natural ventilation is the best choice. The filter element of the air purifier shall also be replaced regularly, otherwise it will not play a purification role.
Experts suggest that in a dry environment, aroma diffuser can be used to alleviate air drying, moisturize the skin and solve the problem of drying
