1. Is mountaineering shoe waterproof?

Answer: Professional mountaineering shoes are waterproof (here refers to professional mountain shoes, not mountaineering shoes worn in summer), waterproof is one of the basic functions of mountaineering shoes.

2. The waterproof principle of Outdoor hiking shoes

Waterproofing of mountaineering shoes can be achieved through two aspects, one is waterproof; the other is to prevent waterproof waterproof.

1. Principles of waterproof water

By spraying waterproofing agents on the hiking shoes, waterproof effect is achieved.In this way, you splash water on the upper. If you immerse it in this short time, the upper will be like a lotus leaf and will not be wet.At the same time, the effect of waterproof watering has a lot to do with the upper material. Pure Skin upper is best waterproof.

Disadvantages: Do not soak water for a long time. After the shoes are worn for a period of time, it is necessary to reintegrate the waterproofing effect and strengthen the waterproof effect, and it will affect the breathability of the shoes.

2. The principle of waterproof membrane waterproof

By adding a layer of waterproof and breathable film to the upper material, this is a porous film. Its pores are 10,000 times smaller than water droplets, and it is thousands of times larger than water vapor molecules. This is the effect of waterproof and breathable.In this way, even if the shoes are soaked in the water for a long time, it will not leak water, and it does not affect the sweat -breathable effect when climbing.Common waterproof materials are: GORE-TEX, Event, Sympa-TEX and so on.

3. The assistance relationship between waterproof and waterproof membrane

It cannot be simply split, whether it is better to spill water or waterproof membrane, because the two are complementary and cooperate intimately.If any semi -diaphragm is completely wet, it will completely lose its breathable effect. Another main function of the outer layer is to keep the semi -diaphragm and do not bubble water and prevent the dirt that is brought in with the water from blocking the semi -diaphragm.

waterproof Climbing shoes pay attention to

1. Do not wear mountaineering shoes as raindrops.Rainwash is completely isolated, and mountaineering shoes will be soaked in water for a long time, and there will be a rainbow absorption and losing waterproof effect.

2. The waterproofness and breathability of mountaineering shoes are inversely proportional.Therefore, we must not blindly pursue waterproofing, and you need to choose the function of Climbing shoes according to the Outdoor conditions.

3. Don't blindly pursue GORE-TEX waterproof shoes. Such waterproof materials shoes are expensive. If you are leisurely climbing and Hiking, ordinary waterproof materials are enough.

1. The breeding method of Dragon Steel iron

1. Soil

Dragon Face Tie likes to penetrate and has strong ventilated sandy loam soil.

2. Watering

When watering, irrigate from the upper part of the plant to keep the soil moist and increase the humidity of the air.Each spring and autumn are important periods. Watering once every 4 days, watering every 1 to 2 days in summer, and spraying water on the leaves to keep the humidity and reduce the temperature.

3. Fertilization

The amount of fertilization of the dragon beard should not be too large, usually fertilizing once every half a month.However, please be careful not to use too thick Fertilizer or Fertilizer.Sometimes because of too thick, the roots are burned.

3. The longer the main branch of the dragon beard, the higher and the higher, and it may be long. At this time, the top will be cut off. Do not worry about damage to it, hit a top, from the incision, you will be separated from the incision.With a few branches, it seems that the plant type is more vigorous and full.

Third, the breeding method of dragon beard iron

The breeding of the dragon iron is generally cuttings and trimming. It is carried out from April to August each year and can be carried out throughout the year.

1. Pile -type cuttings: Fold the leaves directly 1/2-2/3 of the leaves by hand, insert it directly into the clean river sand, and then water it to avoid strong light temporarily.

2. The whole plant is inserted: cut the leaves for short cutting, cutting in a clean river sand and then watering.After that, the air humidity remains at about 70%, and new plants will grow after 1 month.

[Inflatable life jacket] The scope of application principle of inflatable life jacket work inflatable life jacket

Origin -Who invented the "life -saving vest"

In 1944, the former President Bush, as a naval pilot, was shot down over the Pacific Ocean, but he succeeded in parachute and escaped. He was wearing an inflatable "life -saving vest".And the invention of life vestAndrew Totti has always been considered a hero.

However, today, who has invented the "life vest" for decades later, it has caused controversy.After investigation, there was no record of Totti invented in the patent record.A person named Peter Marcus registered the patent of life jacket in 1928, and his design was very similar to the World War II military life jacket.

Is there a patent record of Macus in the archives?

The life -saving vest is an inflatable vest life jacket worn by pilots when flying over the sea.As the inventor, Totti has been praised by people. Of course, the most grateful to him is the old Bush.

Until March this year, after the 89 -year -old Totti died, people still praised his invention as always in the prosecution, grateful for everything he did to save the life of the future president.

But then, the government's documents showed that Peter Marcus had obtained the patent right in 1928.That is, a few years ago when Tott began to design a life jacket, Marcus had begun to study and improve life jackets with the military.Marcus died in 1973.Macus's son and Alvin from Los Angeles provided several certification documents to the Associated Press.The document shows that on December 11, 1928, Marcus's "inflatable life utensils" obtained a patent with patent number 1694714.At that time, Totti was only about 11 years old.

Subsequently, the Associated Press reporter found in the military -related records of the National Archives that since 1930, the Naval military has begun to create a life jacket designed by Marcus.

Toti frankly accepted the praise and wrote the "Congress Records"

Tetty's will and mechanic Russell Hindley revealed that Totti said that when he was a teenager, he sold his life -designed life jacket to the US Army at the time.

"(He) has never said that he is the inventor. He has always called himself a partnership," Xinkeli told the Associated Press reporter that he worked with Totti for decades. ") Have contributed. But Peter Marcus is the inventor. "

Totti has hundreds of invention patent rights, including automatic chicken wiper and respiratory straws for surgery.Over the years, when others praised him invented a life -saving vest, Totti obviously had not denied it.

In 1995, the "ranked" magazine in the United States also wrote Totti.Last year, Republican Dennis Cato from California also praised him to save the life of the future president.Kadaza even wrote Totti's deeds into the Congress record.

The life jacket has continued to improve the reporter's investigation and the inventor failed

Prior to the release of Toti, Alvin said that he had never heard of Totti, let alone Totti selling the life jacket to the military."Selling $ 1500 is a joke at all," he said.According to him, his father, Macus, has obtained thousands of dollars of patent use fees from two authorized rubber companies.However, he also acknowledged that Totti may have improved some improvement in life jacket design.

In order to clarify the matter, the New York Times hired a professional patent lawyer Steven Liberman to inquire about the patent records, but no record of Totti inventing a life jacket was found.The life jacket designed by Marcus is the most similar to the life vest used by the military in the patent record.

In fact, before World War II, people have been constantly improving life jackets.A long time ago in Marcus's registration patent, some people have obtained similar patent rights.Therefore, the life jacket used by the military during World War II may also be from the hands of others.

The working principle of inflatable life jacket

1. Manual inflatable: Pull the pull rope on the inflatable device before or after falling or after falling or after falling or after the water, so that the tie rod is not less than 90 degrees, the thorns are pierced to pierce the gas cylinder film, the high -pressure CO2 gas is poured into the airbag, and the buoyant is generated after the gas swells.

2. Automatic inflation: After the water is dropped into the water, the life jacket is immersed in the water to soften the water sensitive element in the automatic device, loses blocking the needle, and the spring stretch pushes the piercing needle to pierce the gas cylinder sealing film CO2 gas to fill the airbag and generate buoyancy.

3. Blowing the mouth is a one -way valve type, and the one -way valve is automatically closed after blowing.

Scope of application of inflatable life jacket

Inflatable life jackets are widely applicable to the application of passenger ships, yachts, military, water police, water police, water anti -smuggling boats, water construction operations, maritime drilling platforms, flood relief, salvage flood control, pilot, hydrology, water conservancy and other fields.
