[Dome Tent] The roof Tent is practical? The roof Tent gives you a home on the roof

The roof Tent is still a fresh thing for many friends. Some people have heard of it but have never seen it. Some people may have never heard of it. What is the roof Tent?Xiaobian will explain to you the top Tent.

As the name suggests, the roof Tent is a Tent installed on the roof, what?Can I still have a Tent on the roof?Yes, you did not hear it wrong.

Can the roof to bear such a weight?Will it be crushed?

In principle, the roof is 4-5 times that of the car itself, which is the tonnage level. Generally, the roof Tent is about 50kg. In addition, the weight of a family of three is calculated according to 250 kg.In the case, the roof bearing is about 300 kilograms, and everyone does not need to worry about sleeping on the roof at all.

Will you fall when you sleep at night?

Generally, there are railings on both sides of the roof Tent. People who sleep too honestly will not happen from the roof. Of course, the sleepwalking is not counted!

Can only off -road vehicles be installed?Can other cars be installed?

Generally, as long as the area of the roof is larger than the area of the Tent base, it can be installed, such as off -road vehicles, SUVs, sedan cars, etc. The vehicles that cannot be installed are: small vehicles, soft roofs and unfoot vehicles.

Can I drive on a high road?

Here I want to remind everyone: Can't build it on the road, obviously super high, and will be stopped by the police uncle.When driving on the road, you can put away the Tent. Generally, the Tent that is put away will not be super high. If you can't put it directly, you need to remove it.

Regarding the performance of different tents and structures, the performance of the wind and rain, rain, and insulation is different.In addition, different roof tents have different installation methods, which need to be installed according to different products installation methods.

As self -driving tour continues to heat up, the roof Tent has become one of the optional equipment for tourists, and is gradually favored by people. So what are the specific advantages of the roof Tent?

1. The roof Tent replaces the expensive RV and avoids the troubles of not being able to order in the hotel.

2. Compared with the ground Tent, the roof Tent is placed on the roof. As long as the vehicle can reach, the Outdoor Tent can be camped, which is convenient and fast.

3. Compared with the humid environment of the ground Tent, place Outdoor tents on the roof, and with a soft sleeping pad, the comfort is better.

4. Avoid the snake bite that the ground Tent will encounter in the wild, the danger of beast attack.

5. The field of view on the roof is more open, watch the scenery, and take pictures, which is more comfortable.

[Reflective raincoat] What coating is good for reflective Raincoats?Why can reflective raincoat prevent rain and reflect

Reflective raincoat, as the name suggests, is a rainproof clothing that combines rainproof and reflective protection.So how can it be achieved by rain and reflective function?

First of all, from the fabric, the fabrics for raincoat include high dense fabrics and coating fabrics.High density cloth is usually woven from the thin chemical fiber yarn. The density is very high. In addition, the non -water absorption of the chemical fiber yarn itself has led to high -density.

The umbrellas we often use and some basic Raincoats are highly dense fabrics.Of course, this kind of non -water properties are limited to small and medium rainstorms for a period of time. For example, if it is a long rainy environment, umbrellas will still leak rain.

At this point, we need to use another fabric: coating fabric.

To be precise, coating fabrics are a kind of fabric for special process processing, with two layers or even more layers.It is to use solvents or water to put the need for coating gel grains (yesPUglue,A/Cglue,PVC, PEGlossom) Solubinates into drooling, and then in a certain way((Round net, scraper or roller) evenly applied to the fabric (with cotton, polyester, nylon and other substrates), and then fixed through the temperature in the oven to form a layer of uniformly covered with rubber on the surface of the fabric to achieve waterproof waterproof waterproof, Windproof, breathable and other functions.

This is actually simple, but operation is the key!That is, the use of solvents (current fabric fabrics generally use toluene or butanol) to use the coating gel grain (there isPUglue, A/Cglue, PVC, PEPlatform) and other dissolving into drooling (the ratio of the gelatin and the solution, viscosity, etc.) is evenly applied to the fabric (with cotton, polyester, nylon and other substrates) in a scraper, and then passed through the oven passed the ovenThe inner temperature is fixed, so that a layer of uniformly covered with glue on the surface of the fabric is to achieve waterproof, windproof, and vaporic functions!

The coating fabrics or fabrics are generally improved in terms of cracks. These coating fabrics are used in down jacket fabrics, skiing fabrics, work protection clothes fabrics, Outdoor sportswear fabrics, etc.

And if you want Raincoats to have rainproof and protection at the same time on rainy days, we need to add another thing on the basis of the original raincoat: reflective material, usually reflective bands and lattice bands, or reflector coatings.

1. Is the gliding umbrella movement the extreme exercise?

The gliding umbrella is a flying athlete's winged umbrella clothes. It uses air to take off a aerospace. Many friends think that the gliding umbrella is the extreme exercise, but it is not actually the case.

extreme sports combine the collective name of a combination of some difficult and challenging combined sports projects. The gliding umbrella is identified as an aviation sports project at the beginning of its birth, and it does not belong to the category of extreme sports.

However, not all gliding umbrellas do not belong to the extreme exercise, just like driving is not the extreme exercise, but cross -country and drift belong to the extreme sports. The gliding umbrella movement of high mountain gliding gameplay is extreme exercise.

2. Is the gliding umbrella dangerous?

Many friends are very resistant when they hear the gliding umbrella. They think that this sport is very dangerous, but in fact, the sliding umbrella also has different gameplay, and the danger of ordinary gameplay is not high.

The speed of the gliding umbrella is not relying on the wind, the slowest speed of about 23 kilometers per hour without the help of wind power, the slowest speed at the fastest speed of about 60 kilometers per hour, and the cruise speed of about 40 kilometers.The data can be imagined: it is slow, soft, quiet, and elegant floating in the air. There is no fast and exciting feeling. Under the correct control, the feeling of taking off and landing is as easy and simple as up and down stairs.In other words: gliding umbrellas are a floating game in the warm sun and flying in the gentle wind. It is dangerous.Small.

However, gliding umbrellas also have the gameplay, such as precise flights, off -road flight, racing flight, stunt flight, etc. This kind of gliding umbrella movement is highly dangerous. Generally, a small number of skilled enthusiasts will be carried out.

In addition, in the past, there were some "gliding umbrella danger" problems in the development of gliding umbrellas. Most of the reasons were the following categories: no gradual learning theory and flight technology, incorrect or surpassing actual horizontal ability to choose flying equipment, transformation, transformationOr self -made flight equipment; do not follow or ignore the weather conditions, do not follow the rules of flight safety; blindly confident, bold and carelessness and other incorrect attitude and flight concepts.In fact, mastering the correct flight method can face nature with awe and humility, and the gliding umbrella movement is still safer.

3. Is the death rate of gliding umbrellas high?

Just as you can choke up, any exercise has its own unsafe cause. Regarding the problem of gliding umbrella mortality, you need to learn about the sliding umbrella:

1. Leisure gameplay

Enjoy the fun of gliding in your spare time, choose the primary equipment, fly at the gliding umbrella base, the umbrella is slow, the control is general, and the safety factor is relatively high.Don't say death.

2. Competitive flight

Competitive flight requirements are very stubborn for factors such as technology, climate conditions, flight equipment, very few people play, and high danger. This is the extreme exercise. Most of the gliding umbrella mortality rate is contributed by this kind of gameplay.

In addition, it is important to note that some people will choose Wild Fei. This is relatively dangerous, and it is not recommended to fly.

1. What is table tennis shoes

table tennis shoes are a kind of shoes designed for table tennis players. Compared with ordinary sneakers, table tennis shoes have been specially optimized on the soles and upper design to ensure that table tennis players are more flexible, stable and comfortable on the court on the court.Performance.The soles of table tennis shoes are special rubber materials, which are more abrasion and non -slip. At the same time, the design of the upper is also closer to better grab the racket to help table tennis players better control the ball.

2. What are the functions of table tennis shoes

1. Provide stable support:table tennis requires frequent rapid movement and transformation directions, so the soles of table tennis shoes must beWith good grip and stability, it can effectively support the athlete's feet and avoid sprains and other accidents.

2, cushioning decompression:table tennis is generally carried out on hard ground. Frequent Running and jumping will bring greater feetThe impact force, good table tennis shoes must have good cushioning and decompression function, which can reduce the damage to both feet.

3. Peritating sweats:A large amount of sweat produced in exercise needs to be discharged in time, and good breathability table tennis shoes can be effectively reducedDonestion and bacterial breeding caused by sweat accumulation.

4. Light and comfortable:table tennis needs to move frequently and respond quickly, so table tennis shoes must be light and comfortable.It will not increase the burden on athletes and allow athletes to focus more on the competition.

3. Can table tennis shoes usually wear?

table tennis shoes have optimized the characteristics of table tennis in design and production to provide better foot support and stability.

From a functional perspective, the soles of table tennis shoes are softer and have good non -slip performance, which is very useful when playing table tennis.But if you want to wear in daily life, it may not seem appropriate because of the different occasions.For example, in formal business occasions or casual social activities, table tennis shoes may seem not enough or fashionable.

On the other hand, from the perspective of comfort, if you personally feel that the comfort of table tennis shoes is high, and you are willing to wear it, you can usually wear it.After all, the most important function of shoes is to protect the feet and provide comfort.

In general, table tennis shoes are not designed for daily wear. They can usually be worn, but they are not the best choices.

Solving fish seedlings bait good methods common fish fry opening bait

Directly increasing rotor worms in the pond is an effective way to solve the bait of fish seedlings, reduce production costs, and improve the survival rate of fish seedlings.

The rollerworm in the drainage and clear ponds rely on the dormant eggs in the bottom mud to re -germinate.According to determination, in the bottom mud of fish farming ponds, there are more than 10 million rotor eggs per cubic meter per cubic meter. They are "seeds" of wheelglin breeding the following year.The drainage can increase the heat of the dormant eggs in the bottom mud. The Qingtang can remove the enemy's enemy damage and replace the new water itself a benign stimulus.

Tests related to Organic fertilizer show that every 667 Square meters of ponds invest about 26 kg of cow dung or human feces urine to meet the food needs of wheel worms.

Soon after the control of the enemy's pond wheel worms, the water flea also started, because both used bacteria, crumbs and algae as the food, and the filtering ability of the water flea was stronger than that of the wheel worm.Worms are suppressed due to lack of food.Kill the flea with appropriate potions and retain the wheels.

When the new water is applied to the environmental conditions, the wheel worm breeds very quickly. It is 1-2 days after the peak, and hypoxia is prone to occur. Therefore, new water should be added.

In order to ensure the survival rate of fry, in the early stages of breeding, it is often necessary to provide palatable, rich, and nutritious open bait.At present, several commonly used bait in the cultivation of seedlings are egg yolk, soy milk, wheels, algae and aquatic micro -ecological preparations.

1. Egg yolk

Egg yolk is a commonly used fish -opening bait. In the production, the egg yolk can be filtered by 80 measuring silk to make the egg yolk particles smaller, so that it is evenly distributed in the water in the water, which can keep the suspended time around 1h.The amount of bait is within the appropriate range, and the egg yolk can be eaten by the fry better.However, it should be noted that this kind of bait is easily settled and lost, and the water quality is easily corrupted after entering the water, resulting in the slow growth of the fry and the low survival rate.

2. Soymilk

Soy milk is rich in protein and can meet the nutritional needs of fish fry, but soy milk has low nutritional value, is not easy to digest and absorbs, and it is easy to form suspension in water, affecting soluble oxygen, and easily fermented.Promote the rapid reproduction and growth of floats in water bodies, and indirectly provide bait for fish fry.

Three, wheel worms

The size of the wheel worm is 166 m* 230 m. It has good palatability, the highest crude protein content, and the crude fat content is second only to egg yolk, and contains unsaturated fatty acids necessary for a large amount of fish fry, with high nutritional value.The swimming speed is less than 0.02cm / s, and the distribution in the water layer is relatively uniform.Wheels can grow and reproduce in the seedling water body, which not only maintains the stability of its nutrients, but also contaminates the water quality of seedlings.In addition, the research of wheel worm cultivation methods is very rich, and the cultivation technology is relatively mature, which can ensure that the wheel worms have sufficient sources. Therefore, wheelglintes are effective ways to solve the bait of fish seedlings, reduce production costs, improve the survival rate of fish seedlings and quality.

Four, algae

Algae individuals are smaller than wheel worms, and are suitable for use in the early days of the fry opening.With the growth of the fry, the split mouth widen, and wheel worms have become its most suitable bait.The two can complement each other.

5. Aquatic micro -ecological preparation

Aquatic micro -ecological preparations are small, non -toxic side effects, non -pollution and residues, can effectively improve the ecological environment of the breeding, improve immune capacity, inhibit pathogenic microorganisms, and greatly increase the growth rate and survival rate of fish fry.For example, optical bacteria are a nutrient -rich and highly nutritious bacteria. The bacteria are rich in amino acids, folic acid, B vitamins, especially vitamin B12 and biotin content, and physiological activated substance q Q.The volume is 1/20 of the small ball algae. When the organs such as fishes, shrimp, shellfish and other digestive systems that are just hatched are not fully differentiated, optical bacteria can be sucked into the body through gills, so that the fishes have not been completely absorbed in the yolk sac that have not been completely absorbed completelyAt the same time, you can take the bait from the outside to make up for the lack of endogenous nutrition.
