1. How much is the size of the sky curtain Tent

"Size" is the first part to pay attention to when buying the sky -to -Tent. We recommend that you choose the size of the number of actual users.Because of the sky -to -tents on the outside of the Tent, most of them are used as dining places or leisure halls, and their internal tables and chairs must be placed, and the space it occupies is not small.In order to accommodate all personnel and move more comfortably in it or cool, it is necessary to choose a larger size.For example, if two people use, it is recommended that you choose the four -person account.

What kind of fabrication of UV clothing is better

sunlight includes different bands such as visible light, ultraviolet rays (UV), and infrared. Among them, the light of 100-400 nanometer wavelength is ultraviolet rays.UV spectrals are divided into three bands of UVA, UVB, and UVC. Among them, UVA and UVB have the greatest harm to the human body. In short, UVA takes you black and causes a large amount of melanin to settle in the epidermis layer.UVB can penetrate the epidermis, and long -term exposure will cause genetic factor DNA damage, leading to Skin cancer, which accounts for 6.1%of the sunlight.

Polyester fabric clothes have the best effects, which is related to the benzene ring in the structure of polyester fiber molecules. The role of clothes such as cotton, silk, nylon, and adhesive fabrics is poor.Polyester fabrics have a good absorption and reflection effect on ultraviolet rays. They have strong shielding. The passage of ultraviolet rays is less than 3 %, and the ultraviolet prevention rate is still more than 85 %.In addition, the deeper the color, the better the resistance of UV is better. Black, hidden blue, dark green is better than ultraviolet -resistant performance than light blue, light pink, light yellow.The darker the color of the fabric, the smaller the ultraviolet transmission rate.The closer the fabric of the clothes, the stronger the lighting ability, and the less UV rays.Outline prevention of weaving fabrics is better than knitted fabrics.

The working principle of sunscreen

The principle of sunscreen is to use ultraviolet absorbers in mixed fabrics to absorb high -energy ultraviolet rays to transform it to low energy and turn into low -energy thermal energy or electromagnetic waves with short wavelengths, thereby eliminating the harm of ultraviolet rays to human and fabrics.It also uses ultraviolet reflexes to increase the reflection and scattering effects of fabrics on ultraviolet rays to prevent the fabric through fabrics.It has the performance of heatstroke, heat insulation, and cool touch.

It should be noted that the national standards stipulate that UPF & LT; 30, UVA transmission rate & gt; 5%of fabrics cannot be called sunscreen products.Sun protection clothing fabrics include fabrics such as cotton, hemp, silk, hair, chemical fiber, etc. Some of the anti-ultraviolet fabrics compiled by better process have good absorption, conversion, reflection, and scattered ultraviolet rays in the 180-400Nm band.The fabric is non -toxic, no irritation to the Skin, and the human body does not have an allergic reaction, and does not affect the color of the fabric and the performance of hygroscopic vapor.Good anti-ultraviolet fabrics have a good absorption effect on ultraviolet rays of 100-400cm bands, especially UV-A and UV-B. After washing 50 times, the UV transposition is still lower than 1 %.The highest level.

2. What should I do if the swimming ear water is in water

Many people go swimming in summer, and often encounters ears into water. Because water has a certain tension, after entering the narrow outer ear canal, a barrier is formed and the outer ear canal is divided into two sections.The side pressure maintains the balance of the pressure on both sides of the water barrier, so that the water is not easy to flow out automatically.

Sometimes there is a large barrier in the outer ear canal, so it is easier to wrap the water around the ear canal around the after entering the ear canal.After water in the ear, the ears will be stuffy, the hearing decreases, dizziness, and is very uncomfortable, so people are often very urgent to discharge the water.Some people even use unclean clips, match sticks, small keys, etc., so that although the water barrier can be broken and the water flows out, it is also easy to damage the external ear canal and even the tympanic membrane, leading to ear disease.

Third, the water should be discharged in time after water in the ear. The most common method is:

1. Single -foot jumping method:

The ears are down, and the gravity of the water borrows the water to flow out of the ear canal down from the outer canal.

2. Method on the external ear canal:

You can continuously compress the ear screen with palms or pull the auricle with your fingers; or repeatedly do the mouth movement. Movement of the temporal mandibular joint can make the Skin of the outer ear canal continuously up, down, left and rightFlowing from external auditory canal.

3. Method of the outer ear canal:

Use a clean cotton swab gently into the external ear canal, and once you contact the water barrier, you can suck the water.

4. Side lying method:

After trying the above methods, lie down and lie on the side when you sleep at night, that is, the ears that enter the water, but do not block it, because the air pressure will affect the flow of the water after it is blocked.

Because the swimming pool or river water is not clean, the sewage causes the Skin and tympanic infection of the outer ear canal and the tympanic membrane after the ear, or it is not treated properly after the water inside the ear. Obstruct, tympanitis, purulent otitisitis.If the above symptoms occur after water in the ear, you should temporarily stop swimming and go to the Hospital for examination.

4. What should I do if I can't get water in the ear

When water just enters the ear canal, it may not be deep, so the easiest way is to drain the water with one leg.You should go ashore immediately. If you are in the right ear, your head is biased towards the right, the right leg is beating, the left side, and so on. In general, the beating can be drained several times.

If the water enters deeply, it cannot solve the problem in doing so. You can use oily ear drops, such as 2%phenol glycerin drops to ear ear, and once every 3-4 hours. Generally, you can change the unclean water to replace the water.Come out to avoid otitis media.In emergency situations, you can't get ear drops for a while, but most people will prepare eye drops when swimming. Most of the swimming places will also prepare eye drops. You can also use the ear canal with eye drops that do not fail and have no ototoxicity.But afterwards, you must use oily ear droplets to replace water as soon as possible!

Therefore, for those who swim in summer, in addition to preparing eye drops, 2%phenol glycerin drops should also be one of the essential drugs.

It is inevitable that the ears will enter the water when swimming. After taking a bath, the water of the swimming pool remaining in the ears has basically flowing on its own.However, sometimes due to more earwax, a small amount of sewage retention ear canal causes inflammation of the ear.In order to absorb the remaining water and sterilize and anti -inflammatory, you can drip 3-6 drops of medical alcohol into the ear canal after the bath, and stop for a while to let it flow out naturally.

5. How to prevent the ears from entering water

1. Do a good physical examination before swimming.When there is a cricket in the outer ear canal, it should be taken out, otherwise it will easily cause pain after soaking.People with otitis media, such as perforation of the tympanic membrane, and dirty water into the middle ear, can increase otitis media.Therefore, patients with otitis media must be swimming with the consent of the doctor.

2. Use dehydrated cotton with vasel oil during swimming tightly to the outer ear canal, which can play a protective effect.

3. After swimming, excrete the accumulated water in the external ear canal.When drainage, the head is tilted to the side of the water, and the head can be drained with the palm of the same side to drain the water.If itching in the ear, you can use 75%alcohol cotton to gently wipe the external ear canal to disable the hand digging.If you feel pain in your ears, you should go to the Hospital for treatment in time.

4. Pay attention to the posture and method of diving, and do not make the ears directly beaten by water, so as not to occur.

5. In case of water, use the above method to discharge the water.
