What is wheel insect disease and how to prevent it

1. Wheel insect disease is caused by wheel insect disease Caused by a large number of parasitizing the skin or gills of the fish body, the microscopic fins can often see that the worm body is densely covered with the entire fin. The side of the wheel worm is a felt hat, and the reverse side is a round butterfly shape. When it moves, it is like a wheel turning, so it is called a wheel worm.

2. (2) Drug treatment. When this disease occurs in the fish pond, the whole pool is sprinkled with copper sulfate and ferrous sulfate combination (5:2) to make the pool water have a concentration of O.7 mg/l.

3. This disease is caused by careless operation during fishing and transportation, skin damage, and water mold parasitizing.Water fungus grows grayish-white filaments on the surface of the skin. When it is severe, the muscles rot and necrosis, resulting in tadpoles swimming abnormally, loss of appetite, and death from thinness. Prevention and control methods (1) Operate carefully to prevent tadpoles from being injured.

4. The prevention and control method is mainly prevention. First, clean the pond thoroughly with quicklime before stoiling. Second, spray 0.5 grams of copper sulfate and 0.2 grams of ferrous sulfate per cubic meter of water on the whole pool. Third, soak the sick fish in 1% to 2% salt water for 5 minutes. Fourth, soak the fish body with 4 to 5 mg/kg of copper sulfate solution, and pay attention to the washing time according to the water temperature.

Why don't cars install insect nets when they leave the factory? Insect nets

The reason why cars are not equipped with insect nets from the factory: Car insect nets can be installed or not. Different car owners have different driving needs. If they often drive at high speed or often drive in some places with more mosquitoes, they need to be installed.

Why don't you suggest that most car owners install it? Because the car insect net is a very delicate protective net, it will undoubtedly affect the cooling of the heat pipe radiator after installation, resulting in a reduction in the heat dissipation effect of the water tank.

Why don't you recommend most car owners to install it? Because the car insect net is a very fine protective net, it will definitely affect the air cooling of the radiator after installation, resulting in a decrease in the heat dissipation efficiency of the water tank.

It will affect the air cooling of the heat pipe radiator, resulting in a reduction in the heat dissipation effect of the storage tank. Xingtu Lanyue is a model released by Chery's high-end car brand Xingtu in 2021. Xingtu Lanyue does not install insect nets because the insect nets will affect the heat pipe radiator and reduce the heat dissipation effect of the water tank, thus affecting the normal operation of the engine.

The reason why luxury cars are not equipped with insect nets is that it affects the heat dissipation of the vehicle. Car insect nets are mainly used to isolate dust, mosquitoes or willow lint and other substances in the environment, but car owners often find a problem, that is, most luxury cars are not equipped with insect nets.

The insect net of the car can be installed or not. If you often drive at high speed or often drive in some places with more mosquitoes, it is also possible to install one. The insect net of the car is installed at the front of the car, which can prevent mosquito corpses on the surface of the condenser and heat sink at the front of the car.

What should I do if the front of the car is full of insect corpses after driving on the highway

In addition, it can also help clean up stains such as gum, which is relatively cost-effective. When encountering the front of the car is full of insect corpses , it needs to be dealt with as soon as possible, but it can't be washed away with water as soon as the car is turned off.

First of all, when we choose to park, we can try to wipe some residual insects on the car paint and glass with a wet towel after the vehicle is turned off and cools down for a period of time.Here, we can also choose to wipe with warm water, which may be more ideal.

Wipe the insects on the front and glass of the car with a wet cloth/wet wipes as soon as possible, and the flying insect corpses can basically be wiped off within a day.

Is it necessary to add insect nets to cars

Car insect nets can be installed or not. If you often drive on the highway or drive in some places with many mosquitoes, it's okay to install one. The car insect net is installed at the front of the car to prevent mosquito corpses from falling on the condenser and radiator at the front of the car.

The insect net of the car can be installed or not. If you often drive at high speed or often drive in some places with more mosquitoes, it is also possible to install one.The insect net of the car is installed at the front of the car, which can prevent mosquito corpses on the surface of the condenser and heat sink at the front of the car.

Some cars have not cleaned the dirt on the surface of the water tank and condenser for many years. It is recommended to clean up this kind of car. If you just bought a new car, you can install an insect net. After installing the insect-proof net, it is necessary to clean up the bugs on the insect-proof net regularly. When cleaning insect nets, you can blow with a high-pressure air gun or a high-pressure water gun.

Car insect nets are installed selectively. The insect net used in motor vehicles can effectively prevent mosquitoes from entering the water tank and prevent the water tank from being too dirty. The insect net can be installed in two positions: the front of the water tank. It's in front of the middle net of the vehicle.

The air intake filter of the car is installed by the driver himself, which has a certain function.The air intake insect net is also a water tank protective net. The installation method of the protective net is to first remove the front bumper of the vehicle, and then install the protective net between the air conditioner radiator and the air intake grille, and lock it with a wire harness.

What is the best hole in the car insect net

1, .635mm. The international standard of glass fiber insect-proof mesh cloth is 0.635 mm in aperture. Vents and ventilation windows directly connected to the outside world should be equipped with no less than 16 insect-proof screens.

2. Mesh size: 60 mesh insect-proof net has 60 mesh holes per inch, and the mesh size is about 0.25mm x 0.25mm. The 50-mesh insect-proof net has 50 mesh holes per inch, and the size of the mesh hole is about 0.28mm x 0.28mm.

3. "eye" is a customary term, which refers to the number of mesh holes per square inch. 30 mesh means that there are 30 holes. "Φ0.8" means that the diameter of the mesh hole is 0.8mm, which is close to 20 mesh, and "4*4" is a square hole of 4mm square.
