What can I find from the pork nose?They invented the predecessor of the mask

Under the epidemic, masks have become a necessity for our daily out.

Today, the mask we use is very thin and the function is simplified, but to trace the history of the mask invention, the anti -virus mask can be described as a place.

Magical inspiration

The thick and heavy anti -virus mask during the World War I can be called one of the originators of the mask. At the time of the First World War, in order to fight for Belgium with the British and French forces, the Germans brutally put a lot of chemical gas to the battlefield.

At that time, the German army set up about 6,000 chlorine cylinders. After the cylinders were opened, a strong green smoke would emerge. Under the premise of ensuring the wind direction, the chlorine gas drifted to the coalition position with the wind. The coalition forces died about 50,000 soldiers, and wild animals in the surrounding blocks were also "tragically poisoned."

This is because chlorine is a toxic gas with irritating odor. It has high chemical activity and can react with a variety of chemicals and organic matter.

A small amount of chlorine gas can cause respiratory difficulties, cause chest tightness and respiratory syndrome. Entering blood in the blood can cause neurological dysfunction, destroy blood cells, and cause irreversible damage to the human body.

Just as the coalition forces were unable to do the German chemical weapons, some people found a magical phenomenon: the area where chlorine drifting passed, the wild boars survived miraculously.

Scientists have found that the wild boar's nose is 50 times more sensitive than dogs. When it encounters irritating gases, it will bury the nose into the soil and make the soil softened by arch, which plays a role in filtering and adsorbing poisonous gas.

Based on this, Russian chemist Jessky invented the earliest anti -virus mask for the battlefield according to the pig's mouth. From then on, the mask has the effect of anti -virus.

Prior to this, the invention of the mask was only to meet the breathability of miners, firefighters and underwater divers.

Early fire and diving masks

Before the anti -toxic mask has a "anti -virus" attribute, the mask has also experienced several innovative iterations. Its predecessor is the fire mask and diving mask.

At the end of the 17th century, Edmond Harley invented the world's first known diving helmet.

On one side of the small diving helmet on the top of the diver's head, there is a diving clock with oxygen in the diving clock to help the diver breathe under the water. There is a tube on the other side of the diving clock. This tube is responsible for transporting fresh air. This is the first -generation diving helmet.

In the 1960s, with the development of the industrial revolution, miners have long been in the dust environment in the dust. Prussian mining engineer Alexander Von Humboldt designed the world's "earliest dust mask".

Make masks with non -woven fabrics as the main material to help miners reduce inhalation of harmful dust.

But when it comes to the real invention, it is the first true mask that can be filtered out of the air in the first true sense of Lewis Haslet invented in 1849.

This mask is equipped with two row valves and uses wool filters to prevent dust. With this invention, Lewis has obtained a patent of "inhalation or lung protector" and is also the first patent in the history of American patents to purify air purification respirators.

In 1914, another US patent -a safe cover and a smoke protector was successfully applied by Latt Morgan.

Two years later, his anti -toxic mask provided effective rescue for 32 men trapped during an underground tunnel. Morgan promoted this situation nationwide, and finally made the safe cover invented by JP Morgan to the United States. Fire stations from various places.

Some historians believe that Morgan's invention is improved based on the anti -virus mask used by the US military during the First World War.

The perfect safety protection device allowed the exquisite model of JP Morgan's early anti -virus mask to win the gold award of the International Environmental Sanitation and Safety Expo.

At this point, Latt Morgan was officially considered the inventor of modern anti -virus masks.

Principles of anti -virus mask

Today, the anti -virus mask applied to special occasions can greatly increase the protection of the human body. Because modern anti -virus masks are mainly divided into filtration and isolation formulas. According to different categories, the protection principles of anti -toxic masks are different.

Filtering anti -virus masks depend on the original anti -virus charcoal. The structure of anti -virus carbon is more loose than activated carbon, can adsorb more gas, and some will also have a layer of filter paper. The working principle is nothing more than "absorption", which is mainly used for rescue site.

The isolation formal anti -virus mask is mainly to completely isolate the body to the outside world to prevent the invasion of the gas from all aspects.

Provide oxygen to the body through the internal to ensure that the body can still breathe freely in the closed space. This working principle anti -virus mask is more applied to the hypoxic high -altitude and underwater, or the sealing cabin.

Application scenario of anti -virus mask

Such an excellent anti -virus mask, the application scenarios in the daily life are also very rich. Some jobs with hidden safety hazards need to protect the protection of toxic masks at all times, especially the following industries:

Car decoration spraying field

After buying a car, modern people like to do some special color treatment for the car. Therefore, the car paint project is becoming more and more popular. Because the paint contains a lot of harmful substances and irritating gases, it is necessary to wear anti -toxic masks to ensure safety.Picture source www.dehsm.com

Farmers and farmers are engaged in agricultural production work

When cooking crops, in order to prevent insect pests, the relevant practitioners will spray pesticides to the dealer. These pesticides contain strong harmful substances. Whether it is falling on people or breathing into the lungs, it will cause harm to people's bodies. ThereforeProtection of masks.

Home decoration and other fields

During the decoration process, both paint and paint contain a large amount of formaldehyde. Working in such an environment for a long time will cause great damage to the human body. In addition to opening windows and ventilation, daily protection is essential. At this timeMask!
