When performing work related to pollutionof any kind, it is necessary to use protective means, for example, mittens combined (in case you want to protect your hands). You can use them both at home and in various industries.
There are several types of mittens; All of themare made of different fabrics and materials (natural or artificial), designed to work in specific conditions. Advantage of gloves and mittens is practicality, ease in wearing, freedom of movement, durability. In addition to protection from pollution, they protect against injuries during construction, loading, unloading, agricultural and other work.
This is one of the types of protective equipment forhands of man. This model of equipment is made of cotton and canvas cloth. A special, wear-resistant patch on the palm is made of canvas material. It is through the combination of two materials in one product that these mittens are called combined.
To date, there are five types of combined mittens. They are designed for different areas of activity:
The consumer is presented with four sizes of combined mittens: 0, 1, 2, 3.
According to GOST 12.4.010-75 combined mittens are produced using special materials and threads, depending on where they will be used in the future.
So, the products are designed to protect against:
To make the base of such mittensis used a hardened two-sided strips. Also here you can use a severe linen dvunitok, two-strings, half-linen or flax-cap, as well as a two-flute lnolavsan.
In addition, in the manufacture of mittens are usedsemi-linen canvas, material with lavsan fiber of stern diagonal weave, as well as vinyl-skirting-T and elasto-leather (for the manufacture of linings). Here, it is permissible to use a cloth with a mixed "Horizon" cotton-lined cloth with impregnation of a combined type.
For the production of mittens designed forwork in hot shops, materials such as overcoat and flaxen canvas, treated with refractory impregnation and asbestos fabrics (for the base and lining) are used. The lining of the rear part of the product is made of heat-reflecting elasto leather.
The materials described above are used here. The number of refractory impregnation may vary, depending on the operating conditions.
In the manufacture of mittens of this type,linen raincoats and tents smoothly painted with impregnation, semi-linen canvas, treated with waterproof impregnation, as well as rubberized fabrics (for linings and bases).
For protection against concentrated acidsthe manufacturer must use special materials designed for the manufacture of acid-proof equipment, wool woolen acid-proof materials with polypropylene, polyester acid-repellent fabrics.
For the production of mittens designed forprotection against acid of small and medium concentration, materials for working clothes with polypropylene and lavsan, as well as acid-resistant cloth ШХВ-30 are used. Harsh cloth is used only for the manufacture of those products that will later be processed with latex.
Below is a photo of combined mittens.
Here should be used: canvas half-linen, treated with waterproof impregnations, stern cloth, and also a two-linen flax and half-linen.
In the manufacture of mittens designed forprotection against oil products, fabrics with lavsan fiber, half-linen canvas with water impregnation, viscose polyester materials with oil repellency, water repellent vinyl silk "Storm", as well as oil-and-oil resistant elasto leather.
As for the accessories, in the manufacture of equipment for the hands use:
In the manufacture of heat-shielding products,special fenil and sewing threads. These threads, as well as reinforced, are used in the production of products designed to protect against petroleum products. But the reinforced raw materials are not used in heat-protective, alkali-protective and acid-protective models.
Now you have read the description of combined gloves according to GOST 12.4.010-75, which was introduced by the State Committee of Standards of the Council of Ministers of the USSR on January 1, 1976.
