1. How to open the blade with speed skating knife shoes

The just -bought Ice knife shoes need to be used to use it. The ice knife is not open because the blade is blunt, and it cannot be eaten on the ice.There are generally three blade methods of Ice knife shoes:

1. Mechanical grinding

Motorcycles are processed by professional machines.

2. Semi -mechanical grinding

Use sand wheels to grind the blade. Due to the large wear, it is only suitable for rough grinding, and then manually polished.

3. Manual grind

The cost is low and the effect is good. People who have high requirements for skating quality are manually grinding by themselves.Speed skating knife shoe handmade grinding is generally flat grinding: fix the ice shoes on the grinding shelf, bring gloves, and carefully check whether the two knives are on the same plane.You can use the large sand wheels back and forth a few times to see if the grinding marks are uniform.After confirmation, use the large sand wheel (30cm diameter) to make the "8" shape, until the burrs appear on both sides of the blade, and the rough grinding is completed.Then use coarse oil stones to continue making "8" fonts until the grinding traces are particularly small. After removing the knife surface and the burrs on both sides with fine oil stones, a pair of shoes is worn.Remove the ice shoes and clean the surface dust and residue.

Second, Ice knife and shoes are standard

[UV -proof glasses] How to identify the UV -proof function of Sunglasses, what is the coating

What is UV -proof glasses?

The light emitted in the sun is: visual light, infrared, ultraviolet rays, etc.The ultraviolet rays are seriously harmful to the Skin, eyes, etc. of the human body; the ultraviolet rays in the light released by the sunlight are divided into UVA, UVB, and UVC.It is the light of burning black Skin. Most corners of the eyes will absorb this UVB light, so it is necessary to block this light source.

Because UV glasses have the function of polarizing light, they can block all harmful light without affecting the visual light through, which can truly achieve the function of protecting the eyes.

How to identify the ultraviolet function of Sunglasses

Selecting Sunglasses depends on its lens quality, and pay special attention to the function of Sunglasses.So, how to identify whether Sunglasses have the function of anti -ultraviolet rays?In fact, it is not difficult. Put the Sunglasses on a 100 yuan RMB and use a purple light to identify it.

Experts said that the main role of Sunglasses is to prevent strong light and string light, especially ultraviolet irradiation, which protects eye health in summer and is not damaged.

Therefore, when purchasing, you must pay attention to whether there are "UV400" and "UV" logos on the lens and packaging. At the same time, the UV -proof test is also required.

Method 1. Look at the label of Sunglasses

There are Sunglasses with anti -ultraviolet function, generally there are several clear ways:

a) Mark the "UV400": This means that the lens's cut -off wavelength of ultraviolet is 400nm, that is, the maximum value of the maximum value of the spectrum transmission ratio of less than 400nm in the wavelength ()

b) Mark the "UV" and "UV prevention": This means that the lens's deadline for ultraviolet is 380nm, that is, the maximum value of the maximum value of the spectrum transmission ratio of less than 380nm below 380nm;

c) Mark "100%UV absorption": This means that the lens has 100%absorption function on ultraviolet rays, that is, its average transmission ratio in the ultraviolet interval is not more than 0.5%.

The Sunglasses that meet the above requirements are Sunglasses that truly have protection for ultraviolet rays.

Method 2. Use banknotes to verify

In the absence of instruments, ordinary people can also detect whether Sunglasses have the function of anti -ultraviolet rays.

Take a banknote, put the Sunglasses on the anti -counterfeit watermark, and use the banknote pen or the banknote inspection machine to take a look at the lens.If you can still see the watermark, it means that this pair of sun mirrors are not anti -ultraviolet. If you can't see it, it means that this pair of sun mirrors is anti -ultraviolet.

What is the coating of UV -proof glasses

The most effective and most commonly used method to avoid radiation light caused by damage to the eyes is to wear protective glasses.The so -called protective glasses are a filter that can change through light and spectrum.

This type of glasses is divided into two categories. One is absorption and one is a reflex. The former uses the most.

When the lens is manufactured, a part of the metal oxides are added to the general optical glass formula, such as iron, drilling, chromium, cricket, nickel, manganese, and some rare earth metal oxides such as harmony.

These metal oxides can make the glass selectively absorb the electromagnetic waves in a certain band of light, such as the oxide of the and iron can absorb ultraviolet rays in large quantities.Using this glass lens can reduce the amount of some wavelengths through the lens, reduce or prevent damage to the eye.

1. Absorption filter

Also known as Sunglasses.The transmission rate of visible light is about 20%, and the absorption of ultraviolet and infrared is better.There are many colors such as light green, light gray, and light tea, which are used to make sunshade and snow work protection glasses.

Among them, light gray lenses have minimized color recognition; light tea glasses make the blue sky look darker, which reduces the green light through it; the light green lens reduces red light through.

Second, reflective filter

The absorption filter is absorbed by the lens to some wavelength light to reduce the strong light in the eye, but because the lens absorbs certain light, it becomes heat and release, especially the infrared lines and other waves are longer.The light of light makes the eyes feel uncomfortable due to the accumulation of heat.

In actual work life, many situations are combined with absorption and reflective type, that is, a layer of high reflection membrane is placed on the color lens to make the filtering effect more, such as welding, chlorine -library welding, plasma cutting and other operators.You can use this method to solve it.
