What if I accidentally ate aluminum foil

  Recyclable aluminum foil rolls take up a great share in our kitchens and hospitals. We use them to wrap foods for cooking and package pills for safe keeping. Owing to the high frequency of which we get in contact with them, there are times when we accidentally ate aluminum foil and get panic, worrying about all kinds of imaginable results, all of which negative. In fact, don’t worry about this situation. Human body does not absorb aluminium foil paper. The swallowed aluminum foil can be discharged into the intestine with the peristalsis of the intestine, and then discharged from the body through the intestine.

  What if I accidentally ate aluminum foil?

  1. Eat scrambled eggs with leeks appropriately to promote discharge.

  2. Eat some vegetables to promote bowel movements and excrete.

  3. Eat more vegetables and fruits, drink more warm water, this will help swallowed aluminium foil expelled from the body as soon as possible

  4. Eat more crude fiber foods, mainly light semi-liquid food.

  5. Eat small meals frequently.

  6. Go to see the doctor in case of serious uncomfortable feelings.

  Q&A about eating aluminum foil

  1. Will swallowed aluminum foil scratch the gastrointestinal mucosa?

  The surface of the human digestive tract is mucous membranes, secreting mucus, and the surface is smooth. Unless the hard objects may cause incarceration, it will be wrapped in food through the peristalsis of the stomach or intestine, and after eating it can be discharged into the peristalsis The intestine, which is excreted through the intestine, will not cause great harm. It is generally not a problem to eat aluminum foil in medicine packaging, because it is relatively soft, and the scratches may be relatively small. But it takes about 3-5 days to discharge.

  2. Will the foil stick to the stomach wall? Will it cause cancer?

  It will not stick to the stomach wall, and it will not cause cancer.

  3. Why can the aluminium foil be discharged rather than absorbed?

  Because the intestinal tract and stomach are in a high-acid and high-alkaline environment,and human body does not take this kind of material as a nutrient substance, so they will definitely soften and can be discharged. Don’t worry.

  4. Do I need to go to the hospital for treatment?

  No treatment is needed if the amount of eaten aluminium foil piece is not large. Although harmful, it has little effect. It is recommended to observe for a short period of time. If gastrointestinal discomfort occurs, you should go to the hospital for inspection.

Aluminium foil strip for air conditioner fin strip

  Aluminium foil strip is used as air conditioner aluminium fin strip because of its advantages such as low density, good thermal conductivity, easy processing, tasteless, environmental protection and low price. The heat exchanger of air conditioning also develops to ultra-thin and high strength. In the 1980s, the thickness of the heat exchanger sheet was 0.15-0.2ram, but today it is only 0.09-0.15mm. Classification is as below.

  1. Uncoated aluminum foil strip

  Uncoated aluminum foil refers to the rolled and annealed aluminum foil without any form of surface treatment. Ten years ago in China and 15 years ago in foreign countries, all the aluminum foils used for air conditioning heat exchanger were uncoated. About 50% of the heat exchanger used in developed countries are still uncoated aluminum foil, while in China, the ratio is about 60%.

  2. Coated aluminium foil strip

  The so-called coated aluminum foil is to re treat the surface of uncoated aluminum foil, so that it has a special function. In Japan, Germany and other countries with rapid technological development, coated aluminum foil has been used for more than 15 years. In China, the time of using coated aluminum foil is less than 10 years. According to the characteristics of the coated aluminum foil surface, it can also be classified as follows:

  3. Corrosion resistant aluminium foil strip

  The surface of the corrosion-resistant aluminum foil product has a certain corrosion-resistant protective layer. The air conditioning heat exchange sheet made of the product can be applied to the worse areas, and can significantly improve the service life of the air conditioning. At the same time, due to the improvement of the corrosion resistance of the heat exchanger, the formation of corrosion powder on the surface is greatly reduced, thus improving the ventilation quality and purifying the air in the air conditioning room.

  4. Hydrophilic aluminum fin strip

  The surface of hydrophilic aluminum foil has strong hydrophilicity. The hydrophilicity is determined by the angle formed by water sticking to the surface of aluminum foil, as shown in Figure 1. The smaller the a angle is, the better the hydrophilicity is; otherwise, the worse the hydrophilicity is. Generally, angle a is less than 35. It belongs to hydrophilic property. Hydrophilic aluminum foil is generally used in evaporator of air conditioner. The main function of the utility model is to make the moisture in the hot air easily spread and flow down the sheet when it condenses on the heat exchange sheet into water drops. In this way, the ventilation effect of the heat exchanger can be avoided due to the “bridging” of the water drops between the heat exchange sheets, so as to improve the heat exchange rate of the air conditioner, and save electric energy under the condition of the same cooling capacity. Before, the general hydrophilic aluminum foil in the market has not only good hydrophilic surface, but also high corrosion resistance, which makes the performance of air conditioning more optimized.

  5. Hydrophobic aluminium foil strip

  Hydrophobic aluminum foil is also called water repellent aluminum foil. Its surface performance is opposite to hydrophilic aluminum foil. That is to say, when the condensate condenses to the surface of the aluminum foil, the contact angle with the 36 wide aluminum coil stock foil is relatively large, generally at 75. above. The larger the angle, the better the water repellency. The ultimate goal of using hydrophobic aluminum foil is the same as that of hydrophilic aluminum foil, that is, not to let the condensed water stay between the heat exchange sheets. The difference is that the hydrophobic aluminum foil can remove the condensation water between the heat exchanger sheets by increasing the contact angle between the condensation water and the heat exchanger sheets, so that the condensation water can form water drops which are easy to slide.

  6. Self lubricating aluminum foil fin strip

  In the process of processing and manufacturing, the air conditioner heat exchanger generally needs to add lubricating oil to its surface, then punch and flanging, and finally wash the lubricating oil with trichloroethylene. Because trichloroethylene is harmful to human body, in order to reduce this process, self-lubricating aluminum foil is produced accordingly. As the name implies, the self-lubricating aluminum foil does not need to be added with lubricating oil alone when it is processed, and the lubrication during the processing is undertaken by the pre-treatment film on the surface of the aluminum foil. Since no special lubricating oil is needed, the subsequent cleaning and drying process of trichloroethylene is also omitted.

  7. Mould proof aluminum air conditioner foil

  Mould proof aluminum foil is mainly used for indoor unit of air-conditioning. Its main function is to prevent the surface of heat exchanger from mildew due to long use or placement time, so as to significantly improve the ventilation quality of air-conditioning, prevent the generation of abnormal smell, and effectively improve the indoor environment of air-conditioning.

Packaging process for aluminium coil and foil roll products

  The packing box and packing method for aluminium coil and foil rolls shall be selected according to the product specification and size.

The height of the bottom bracket shall meet the requirements of forklift transportation. After aluminum coil foil products pass the inspection and are sealed with inspection stamp, a layer of strong neutral or weak acid material shall be wrapped outside, and the joint shall be sealed with a tape or label.

  The end face of the package is padded to protect the end face of the aluminum coil rolls. Add dry explosive, cover the material bag, plug the part of the two ends of the material bag beyond the aluminum record into the tube core, seal it with a suitable material head and put it into the packing box. After the product is packed, a layer of anti Lake paper or material cloth shall be covered on it. After the packing list is placed, it can be covered and sealed with steel belt. The steel belt shall be tied in a circle.

packed aluminum coil foil products

  Conventional packaging for aluminium foil or coil rolls: for aluminum roll with a thickness of more than 0.05mm and a hard state every day, it can be packed with a tripod, and its packaging shall meet the requirements of transportation. The well frame is made of wood, and the upper and lower parts are made of two battens respectively. The height of the lower battens shall meet the requirements of the next train operation. The upper battens shall be made of arc shape corresponding to the roll radial direction. The upper and lower battens shall be fixed with poles, and the length of the poles shall be lower than the surface of the upper battens to complete the aluminum burn.

  Firstly, a layer of strong neutral or weak acid material (generally high release) shall be placed on the outside of the aluminum foil rolls, and the packing list shall be placed, and the lap joint shall be firmly adhered with adhesive tape. A soft pad is placed on the end face to protect the end face of the aluminum foil roll.

  Secondly, add dry explosive, wrap the whole material roll with the whole plastic cloth, the outer layer of the lap joint should be expected to have the material cloth mouth downward and be firmly stuck with adhesive tape, and plug the redundant parts at both ends of the plastic cloth into the pipe core. Finally, the rainproof cardboard with the same size is used to wrap the entire aluminum coil and seal the two ends along the circumference direction, and the joints between the end face and the circumference and all the gaps are firmly bonded with adhesive tape. Put the wrapped aluminum foil on the derrick and fix it with steel belt along the circumference direction, which shall be tied firmly. Put a box plate on the end face of the packed aluminum foil roll. In addition to the load-bearing and packaging costs of boxes and trellis, the transportation mode and the transportation and handling capacity of users should also be considered. Generally, the packaging weight of each aluminum coil of our company is 2.6 tons.

  Export packaging method of aluminium coil suppliers: aluminum coil is a product with large export volume. The export packaging is usually in the form of plain well frame, the external part is fixed with steel belt, the external part of aluminum coil is provided with double-layer rainproof cloth, the internal part is moisture-proof, and the sealed packaging is adopted, which is suitable for sea transportation.
