Summer is a good time for cold drinks, and many female friends are even more greedy for the cool summer season and eat without restraint. In fact, eating cold drinks in summer has many taboos. Eating unreasonably naturally affects our health. Summer heats and cools in hot summers 1, when eating Some people like to eat cold drinks when they eat, such as drinking a large amount of frozen fruit juice, and even prefer to use the cool white brewed rice that has just been taken out of the refrigerator to make them feel happy and relieve heat. Others like to eat just after eating. A big cup of ice cream. This is not the proper way to eat. Because the stomach is suddenly subjected to a large number of cold drinks, the “invasion†will cause it to suddenly contract, and the peristalsis will slow or even stop, and the digestive function of the gastrointestinal tract will also weaken or even stop. It is not until the stomach returns to normal temperature that the digestive function is possible. Go back to normal. This time will take at least 30 minutes. Over time, this will lead to disorders of the stomach and cause a variety of stomach diseases. What's more, eating cold drinks while eating, the sudden contraction of the stomach may cause the gastric mucosa to tear, cause stomach bleeding, or cause food and stomach acid to directly contact the stomach wall, causing different degrees of pain. Generally speaking, for those who have stomach problems, doctors will not forget to sip a cold drink. This is the reason, because cold drinks tend to aggravate their condition. In addition, cold-water rice is particularly undesirable because bubbling rice is not conducive to chewing, increasing the stomach burden, but also dilute the gastric juice, unfavorable to digestion. 2, after strenuous exercise Some people like to eat cold drinks right after strenuous exercise, even when they are sweating or sweating. It feels so happy, but it is actually a practice that is harmful to health. Because people are warm-blooded animals, body temperature is usually maintained at about 37 °C, but after exercise, it can rise to about 39 °C, then immediately eat cold drinks, will strongly stimulate the gastrointestinal tract, causing gastrointestinal smooth muscle spasm, sudden blood vessel contraction , causing gastrointestinal disorders, leading to indigestion. In addition, after strenuous exercise due to accelerated blood circulation, throat congestion, if suddenly stimulated by cold drinks, can cause throat disorders, causing sore throat, hoarseness and other symptoms. The correct approach is: After strenuous exercise, rest for half an hour, wait for body temperature to return to normal, and then slowly eat cold drinks, but you can not eat too much at once. 3, the elderly The elderly have weaker body immunity, especially the decline of digestive tract function, and the tolerance to cold drinks is greatly reduced. Excessive glutinous cold drinks may not only cause gastrointestinal digestive disorders, but may also induce more serious diseases. In particular, elderly people who are in poor physical condition are advised to fast their cold drinks. 4, infants and young children healthy diet The development of gastrointestinal tract in infants and young children is not yet sound, and it is extremely sensitive to the stimulation of cold drinks. Giving infants and young children to eat cold drinks can easily cause diarrhea, abdominal pain, sore throat, and cough. What's more, because infants and young children have thinner bowels than adults, the mesenteries that wrap around the surface of the bowel are relatively long and soft and do not hold the intestine firmly on the posterior abdominal wall. In addition, the digestive function of infants and young children is not yet complete. Cold drinks prone to intussusception, the consequences are very serious, the worst possible intestinal necrosis. Therefore, infants younger than 2 years old are advised not to eat any cold drinks. For children older than this age, parents are also advised not to allow them to eat too much cold drinks, especially for the timing and variety of children's cold drinks. Before parents buy cold drinks for their children, parents should carefully read the product ingredient list. It is best not to allow children to eat cold drinks that contain too many artificial additives such as pigments and flavors. 5. When there is doubt about health The high temperature in the summer, the bacteria prone to breed, the food is easily corrupted, and the use of milk, sugar, and other raw materials in some cold drinks creates favorable conditions for the breeding and reproduction of bacteria. Some people believe that cold drinks are mostly stored at subzero temperatures in freezers, and even at minus ten degrees, even if some bacteria may have been frozen to death, some harmful bacteria such as Salmonella typhi and S. pyogenes can be at -170°C. Survival, therefore, thinks that it is not correct to insure food hygiene for cold drinks when it is frozen. When you buy cold drinks, you should pay attention to observations. For beverages packed in bottles or Tetra Pak, if you find flatulence, bottle wall deformation, etc., absolutely do not eat; for ice cream, ice cream and other solid-state cold drinks, in addition to pay attention to the production date, we must observe the packaging, Do not buy or eat foods that are abnormal in shape, as this may be a product that has been melted and then frozen. It may even be a product that has repeatedly caused problems during the cold chain process. In addition, try to buy products from big manufacturers and big brands, because such products may enjoy higher protection relative to the organization of production raw materials, control of production processes, and cold chain transportation. In short, do not eat when you are concerned about the health conditions of cold drinks. 6, during menstruation or pregnancy Women's menstrual period too cold, easily lead to pelvic visceral vasoconstriction and spasm, resulting in dysmenorrhea and even prostration; pregnant women eat too cold, you may make uterine contraction worse, unfavorable to the fetus, and even cause miscarriage. Both menstrual women and pregnant women should be careful to drink cold. Although the summer cold drinks can cool down, but improper consumption will have an impact on the body, a reasonable diet, and a healthy summer time. Venlo structure is a popular one at present. This architecture uses horizontal girder as main bearer, forming a stable structure with columns. There is consolidation between horizontal girder and column, and hinge is used to connect column and foundation.

In Venlo greenhouse, foundation is made of reinforced concrete and the side wall is made of brick or reinforced concrete plate. The steel frame always use hot dip galvanized light steel. Roof beam adopts horizontal girder structure and using herringbone connection. The horizontal girder bears 2 or more roofs, which is made of aluminum alloy. This material is used as roof structure material and also glass inlay material. Other beams using gutter style to minimize the section. Delighting material of the roof and side wall using the hollow double-layer or multilayer PC board.
PC board is mainly made of PC/PET/PMMA/PP materials, it need sun screen coating to resist ultraviolet resist and ageing, and it is also required to be anti condensation and antidrug.
As a kind of light material, use PC board can greatly reduce the weight of greenhouse structure, and corresponding reduced the size of the steel frame, which saving the cost of steel.
