[Source of raincoat] The historical raincoat of raincoat is due to a "mistake" of workers

The raincoat on rainy days, plus its strong wrapping silhouette, plays an important role in shaping the character image. Remember to have a Chekhov's "People Put in the Set" in High school. The character is lonely. Burchov, who is timid and fearful, is "abiding by the law", is that it always takes umbrellas, raings, and Raincoats in the sunny day. Essence

Although the raincoat made of rubber is not permeable, it is hard and crispy. It is neither beautiful nor comfortable to wear on the body. British metallurgist Parker decided to improve this kind of clothes. Use carbonide to do solvents, dissolve rubber, make waterproofing technology, and apply for patent rights, and sell it to a person named Charles, and the raincoat starts to produce a lot.

After entering the 20th century, with the emergence of plastic and various waterproof fabrics, the style and color of Raincoats are becoming more and more fashionable. It has no longer simply used as a functional jacket and has become a fashion item.

1. What is the difference between Beach towel and bath towel

beach towels and bath towels are a type of towels, and they look relatively similar, but they are still very different. The difference between beach towels and bath towels is mainly reflected in the following aspects:

1. Appearance

But look at the appearance, you can intuitively distinguish the beach towels and bath towels, because the color of the Beach towel will be more vivid and more patterns.It usually takes pictures, and the stylish and beautiful towels are better to take pictures; and bath towels are usually designed as light or dark single colors, which are matched with the bathroom style.

2. Size

The size of the Beach towel is slightly larger than the ordinary bath towel. Generally, there is probably one person in ordinary bath towels, and the Beach towel is paved on the beach to facilitate the user to take a day bath. Therefore, it will be designed to be larger.The head and feet are exposed to the sand.

3. Thickness

The thickness of the bath towels is very thick, because as a bath towel, its water absorption is very good, which is convenient to wipe the body out of the bathroom quickly after taking a shower; the thickness of the Beach towel is relatively thin.So good, but it is enough to make you dry your body quickly, and it is thinner and more convenient to carry.

4. Use

The bath towels we usually use are used for family shower. It feels soft and water absorption.However, when the towel was washed in seawater once or twice, it felt that there would be a odor and no longer softened.However, due to the particularity of the use of the Beach towel, these issues are considered in production. Even if they are repeatedly used in seawater, they will not have a smell and dry feeling.

2. Can the Beach towel be used as a bath towel?

Can.

The Beach towel is very large. It can be wrapped on the waist like a bath towel, put on the body, or used to wipe the body, but the Beach towel will be larger than the bath towel, which does not affect the use;It is impossible to use a Beach towel. On the one hand, the design of the bath towel itself is not used on the beach. On the other hand, the bath towels are not as durable as the Beach towel. Unless it is a special case, it is not recommended to replace the Beach towel with a bath towel.

What are the Diving equipment

1. Facial mirror

The diving mirrors on the market now are mainly divided into three types: silicone, rubber, and PVC; rubber and PVC materials generally have some odors. The rubber material has rarely appeared in the leisure market. Generally, a few diving mirrors are made of silicone materialsIt is non -toxic and tasteless. The price is slightly more expensive than PVC, but it is softer, more durable, and more comfortable to wear.

The appearance is mainly divided into dual lenses and single lenses. There are no differences in these two uses, and the field of vision is similar. The advantage of dual lenses can be equipped with close -up lenses; the selection is mainly based on whether it meets its face shape and personal preferences; there is another kind of one; there is also one is that there is one.Fullface mask; Full mask, the design of this type of mask makes the divers not have to include the respirator in the mouth and combine the communication interface, mainly to enable the diver to achieve underwater calls; mostly for engineering diving.

2. Breathing Tube

The material of the respiratory Tube is also mainly divided into silicone, PVC, which is better for silicone tubes; structures are divided into all-dry and non-dry type;It is welcomed by junior players to prevent water from entering; but from a practical perspective, it is still a traditional non -dry respiratory Tube with simple structure and smoother breathing.

Buying note: The choice of respiratory Tube must meet the principles of ergonomics and mechanical design. The diameter size and length must be appropriate to facilitate drainage, and the design of the water stop valve must be available to prevent seawater from pouring in.The part of the bite should be the best choice for bite comfort.

3. Cold -proof clothing

Cold -proof clothing, also known as diving suit.It is mainly divided into wet, semi -dry, all -dry, wet type divided into 3 mm, 5 mm, 7 mm and other thickness.Wearing semi -dry and full -drying potentials, you can keep your body not wet, and you can also wear warm clothes in the interior. The insulation effect is the best.The choice of diving coats is mainly determined according to the water temperature of the diving environment; tropical or temperate waters, 3 mm thick wetwear are the most commonly used; the lower the water temperature, the thicker the need to choose a divingSemi -dry or full -drying; all dry clothes can even achieve under ice diving.

Buying note: In order to achieve the effect of preventing the cold, the cold -proof clothing must be fitted, soft, easy to unload, and not easy to deform, and does not affect the ability of divers to move.Secondly, choose the tricks you like.

4. Frog shoes

The frog shoes are mainly packed with foot frog shoes, and the adjustable frog shoes; the set of foot can only be worn, light and easy to carry; suitable for snorkeling, or indoor, and diving on the board.The role is to enhance the driving force and maintain balance.Floating activities are generally selected. Many junior players can easily ignore the role of frog shoes.

In fact, diving in the wild, frog shoes are more important than respiratory Tube. Wearing frog shoes at least half a life jacket.

5, buoyancy regulating vest

The BC style is mainly divided into jackets, system, backup type; bribium type is mostly used for technical diving.There are many models of BC, and there are many details in different brand models. When choosing, you should according to the specific needs of your personal; there is also a pre -type BC that is no longer used for water diving.It is very popular in snorkeling activities.

Buying note: The buoyancy regulating vest should be different due to the weight of the personnel, so you need to choose a buoyancy regulating vest suitable for personal weight.

6. First -level regulator

A diving brand has a variety of types of regulators to choose from, which is suitable for different needs; taking scubapro regulator as an example, MK2 is suitable for most leisure diving and diving training; MK17 is a fully enclosed design, especially suitable for ice diving, polluting water sources, etc.Special environment diving; MK25 can be used for large -depth diving.

Buying note: The first -level regulator and the secondary regulator are a group of combinations. The difference is that the first -level regulator is connected to the gas cylinder, while the secondary tunnel is used in the part of the mouth.

7. Second -level regulator

The regulator (also known as the respiratory) is divided into single Tube and dual -Tube type. When choosing, you should cooperate with your mouth shape and snake Tube.When cleaning and cleaning up, it should be placed in an environment where dry and is not easy to contact with salt, and should be checked once at least two years.

The spare secondary regulator is the standard and training subject in leisure Diving equipment.But I personally think that there is basically no chance to use it.If you need to spare gas sources, a better choice is to equip an emergency gas cylinder.

8. Diving instrument

The diving instrument has a single pressure gauge, a two -connected table, and a three -meter table; the single pressure gauge can only display the pressure of the gas cylinder, so that the diver can know the gas of the gas cylinder at any time;The depth of the pressure and the diver is located; one more northern needle of the three -meter table, when the diver needs to master the direction; there is also a rare four -meter table, an additional thermometer.

9. gas cylinder

The gas cylinder is divided into steel cylinders and aluminum bottles.Leisure diving mainly uses imported 12 -liter aluminum bottles. The aluminum bottle is resistant to corrosion resistance and long life.There are some supporters of domestic 12 -liter steel bottles and aluminum bottles in the underwater operation market. The main features are cheap, but the cylinders are easy to rust, and some new steel bottles have odors.

Buying note: depends on the depth of water and the amount of gas needed by the individual, and cooperate with your body shape and physical strength to choose the appropriate gas cylinder.Therefore, too long or too large gas cylinders will affect the ability of activity; and choose to prepare a gas cylinder with air storage device as much as possible.

10. Dignation

Due to the large buoyancy of the submersible, we must configure the heavy -duty and buoyant, otherwise the diver cannot be dived.The weight blocks are basically lead materials, which are divided into naked lead and environmentally friendly plastic lead blocks. The lead itself is toxic. It is recommended to use more safer plastic lead blocks.

11. hook, fast unloading ring

As the name suggests, it is used to help quickly load and unload the items around you.It is mainly used for Hanging cameras, flashlights, and knocks on the BC's Hanging ring.

12, gloves

Hands immersed in water are easily injured, so gloves are used to prevent injuries to being cut by thorns or sharp rocks.Depending on the water temperature, different thin gloves are optional.

13. Diving boots

Diving boots are mainly prevented from slipping in the slippery rocks.It is more suitable in China to use the foundation bottom, and it is more suitable for boat dives to use rubber bottoming shoes; and be careful to closely consolidate with frog shoes.

14. Diving knife

It is used to cut off the remaining fish or fish network cables in the sea to avoid entangled divers.It is a guarantee of diving safety.Ordinary stainless steel dive knives cannot remain sharp in seawater and are easy to rust.A better knife is a titanium alloy diving knife, light weight, sharp, never rust, but the price is higher.

15. lighting in the water

It is used to spy the dark world in the sea. The greater flashlight and lighting Lights are particularly effective. It is a must -have for diving at night or dark fields.

16. record board in water

Instead of communicating in water, in addition to communicating with gestures, another pipeline is to record the board in the water and write it down as a two -way between staff.

17. Diving computer watch

Diving computers have gradually become standard accessories that have gradually become diving activities.It is mainly used to ensure that divers stay within the depth and time limit.record the diving process, etc.

How much is a Diving equipment?

If it is snorkeling: the face mirror breathing Tube is sufficient, and dozens of RMB to hundreds of dollars can choose.

Deep diving (water diving): diving mirror, respiratory Tube, foot scallion, first -class head, secondary head, buoyancy regulating vest, three -meter table, gas cylinder, Diving clothes, etc., are about 4,000 in domestic. If the brand, the priceIt will be higher.
