There are a large number of devices that guarantee safety in certain cases. However, even against this background, the review of NBT protective shields is very important. It is necessary to know the areas of application of these devices, the specifics of individual versions and the nuances of choice.
Peculiarities
Speaking about the NBT shields, it is worth pointing out that they allow you to protect the face and especially the eyes from various mechanical particles … Such products meet the most strict European Union standards . The main structural material is polycarbonate, which is resistant to mechanical stress.
It can be transparent or tinted. The attachment on the head (above the face) is very secure.
It is also worth considering the following:
- some versions use impact-resistant polycarbonate;
- face shield thickness - less than 1 mm;
- typical plate dimensions 34x22 cm.
Applications
The protective shield of the NBT series is intended for:
- for turning wood and metal blanks;
- for grinding scale and welded seams using electrified tools;
- for grinding semi-finished products and finished products;
- for other works that are accompanied by the appearance of flying debris, debris and shavings.
Such designs are used in many industries:
- automobile;
- petrochemistry;
- metallurgy;
- metalworking;
- construction and repair of buildings, structures;
- chemical;
- gas production.
Model overview

- permissible operating temperatures range from -40 to +80 degrees.
Face shield NBT-1 has a screen (mask) made of polycarbonate. Of course, they do not take any polycarbonate, but only flawlessly transparent and resistant to high temperatures. The headgear of the Standard format works very reliably. The device as a whole guarantees reliable protection against particles whose energy does not exceed 5.9 J.
Additionally, a visor is used, for the manufacture of which they take heat-resistant plastic.
The guard of the NBT-2 model is supplemented with a chin .2 mm transparent polycarbonate is mechanically resistant. Since the screen can be adjusted, it is placed in a comfortable working position. The headband of the shield is also adjusted. The shield is compatible with almost all work goggles and respirators.
Also worth noting:
- compliance with the first optical class;
- protection against solid particles with a kinetic energy of at least 15 J;
- working temperatures from -50 to +130 degrees;
- reliable protection against sparks and splashes, drops of non-aggressive liquids;
- approximate gross weight 0.5 kg.
Selection Tips
The purpose of the protective shield is of decisive importance here. Each industry has its own requirements and standards. So, for welders, the use of high-level light filters will be a mandatory requirement. It is advisable to check how well the headband of the visor is adjusted. Product weight is also very important - a balance must be struck between security and ergonomics.
It is very helpful to find out what optional accessories are.
The higher the level of protection, all other things being equal, the better. It is very good if the shield saves from :
- temperature rise;
- corrosive substances;
- rather large mechanical fragments.
