Recently, the first batch of 500 tons of new pipe special material QHM22F was developed and produced by Sinopec Qilu Petrochemical. There is no production precedent for this product in China, which fills the gap in the market for similar pipe materials. At present, Qilu Petrochemical has a daily production capacity of 500 tons. QHM22F is a special material for high temperature resistant polyethylene pipe. It is widely used in construction geothermal heating, metal pipe and other fields. It has the advantages of good connection performance, long service life, good environmental flexibility, etc. The market prospect is promising, in the high-density polyethylene product industry. In general weak conditions, the profitability of such products continues to increase. Due to the high production technology and high safety risk of the product, there are 200,000 to 300,000 tons of domestic demand each year, all of which are met by imports. "Because of equipment, technology, and other reasons, we have a significant gap with foreign advanced companies in the production of such products," said Sun Haitao, Minister of Production Management of Qilu Petrochemical Plastics Factory. “The gap is the potential, and tapping the potential is the benefit.†said Li Anxi, assistant general manager of China Petrochemical Corporation and general manager of Qilu Petrochemicals. Qilu Petrochemical combines production practice and follows the management philosophy of “economic operation is the level†to fully promote the development of such products. The biggest problem they face is that there is no precedent for this special material production technology in China. Qilu Petrochemical held several seminars to carefully arrange new product developments, adopt risk prevention measures, and perform tests on the production staff of production workshops to ensure that the production process is completely secure. On March 31, new products were successfully produced. After testing, all performance indicators have reached the standards of similar foreign products. Experts believe that this special material, as a polyethylene high-tech product, will become another growth point for corporate profits. D03 Bottle Aroma Diffuser 200ML

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
