Most people know what foods need to be eaten in the spring to promote their own health. But do you know that there is something to eat in the spring that will cause you to have problems? Here are five kinds of fruits that can't be eaten in the spring. Don't let your greedy mouth cause the hidden danger of the body. Strawberry Chinese medicine believes that strawberries have the effect of detoxification, heat-clearing and heat-removing. In spring, people's liver and fire are often quite strong, and eating strawberries can play an inhibitory role. In addition, the best strawberries to eat after a meal, because it contains a lot of pectin and cellulose, can promote gastrointestinal motility, help digestion, improve constipation, prevent acne, colon cancer. Reasons for not eating more: In the middle, there are hollow, irregularly shaped and oversized strawberries. Except for a few high-yield varieties, the use of excessive hormones is generally used. After ripening agents or other hormone drugs were used in strawberry, the growth cycle became shorter and the color was brighter. However, the inherent fragrance of strawberry was diluted and the taste was lacking. sugar cane Most of the sugar cane in the spring are in autumn stocks, and after a winter of storage, they are highly susceptible to deterioration, and floc-like or fluffy white substances appear at the end of the cane. After cutting, there will be red filaments on the section. Some people did not carefully select the sugar cane, cut it and saw the red thread and thought it was a normal phenomenon, resulting in sugar cane poisoning after eating. pineapple Some people will experience nausea, vomiting, abdominal pain, diarrhea, tingling lips, itchy skin and other allergies after eating pineapple. This is because pineapple contains bismuth and bromelain. In order to prevent allergic reactions, pineapples must be soaked in dilute salt water for more than 10 minutes after the pineapple is chopped and destroyed after bromelain is eaten. banana In order to make the banana skin yellow and look good, some unscrupulous traders use excessive sulfur dioxide to ripen, but the flesh is still hard to eat, not sweet at all. Sulfur dioxide is harmful to the human body. The correct method is to heat and smoke. grape Some unscrupulous traders and fruit growers diluted the ripeners ethylene and water in proportion, and soaked no mature green grapes in the diluted solution. After a couple of days, the green grapes will become purple grapes.
Metal fiber sintered felt filter medium
Describe:
Metal fiber sintered felt (diameter to micron) is made of non-woven, superimposed and sintered at high temperature.
Characteristics
In stainless steel sintered felt, the pore gradient is formed by different pore size layers, which can control the filtration accuracy and the amount of dirt absorption of stainless steel sintered felt. It has the characteristics of three-dimensional mesh, porous structure, high porosity, large surface area, uniform distribution of pore size and so on. As a result of the above structure and characteristics, stainless steel sintered felt can effectively compensate for the weakness of metal NetEase plugging and vulnerability, and can make up for the fragility of powder filtration products and the shortage of small flow rate. It has the heat resistance of ordinary filter paper and filter cloth that can not be compared with each other. The stainless steel metal sintered felt is an ideal Filter Material with high temperature resistance, corrosion resistance and high precision
1. The pressure rises slowly, the replacement period is long
2. High porosity and good permeability, small pressure loss, large flow rate
3. Corrosion resistance, high temperature: acid, alkali, organic solvents, pharmaceuticals and other corrosion, can be used in the environment of 480 ℃ for a long time
4. Easy to process, molding, welding
5. According to the requirements of users, special production of enhanced, thickened, protective network and other specifications.
Applications:
Stainless steel sintered felt has excellent filtration performance and is an ideal high-temperature, corrosion-resistant and high-precision filter material. Widely used in polymer filtration, petrochemical, electronic high temperature gas dedusting, refining process filtration, viscose filtration, ultrafilter prefiltration, vacuum pump protection filter, filter membrane support, catalyst carrier, automotive airbag, Aircraft, ships and other fuel filtering, hydraulic system filtering.
