Materials (edit)
Knowing what gloves are made of is necessary for the correct selection of products appropriate to the operating conditions. The main materials used in the manufacture of hand protection are:
- cotton fibers used for the manufacture of materials of various weights and grades of knitting. They are hypoallergenic and have excellent air permeability;
- split, which is the lower part of sheets of leather cut through the thickness. Combines high temperature resistance, fire resistance with high strength;
- latex, which provides gloves with a snug fit and reliable protection for hands due to elasticity;
- neoprene with high resistance to humid environments;
- vinyl resistant to acids, alkalis, alcohol. With high tear resistance, the material is highly breathable;
- nitrile with high puncture resistance.
In the manufacture of gloves, materials are often combined to improve performance.
Chemical resistant gloves made from latex
Latex is a material based on natural rubber. To obtain a latex product, a saline solution containing positively charged metal particles (cations) is applied to the mold, after which it is immersed in latex. A chemical reaction takes place based on the interaction of cations and latex particles: the cations discharge the positively charged rubber particles, as a result of which the latter are deposited on the form as a thin film. The result is a tough and resilient polymer material.
Latex Glove Manufacturing
Modern acid-alkali-resistant gloves of both types have 2 layers. The upper one comes with the addition of an adsorbent - soot, and the inner one consists of highly purified latex, so the material reliably protects the hands and does not cause irritation on the skin.
9.3. Information provided by the manufacturer
Information should
accompany gloves and provided upon request. Information should
include:
a) name and full
manufacturer's address or
an official representative;
b) product marking in
in accordance with 9.1.2 b);
c) link to
the corresponding standard;
d) available sizes and, c
if necessary, information on;
e) in case
necessary, as indicated in 9.2.2, a pictogram indicating protective
properties, indicating the characteristics of harmful factors. Further should be
explanation of the performance characteristics of hand PPE
and references to relevant standards;
f) a list of substances
contained in a glove that can cause allergies;
g) instructions for
application;
i) care instructions
(washing or dry cleaning conditions) and storage;
j) type of packaging for
transportation and storage;
k) shelf life for
gloves and packaging with a significant decrease in protective properties as a result
storage.
Decoding of marking and technical characteristics
In accordance with the requirements of the standards, the following symbols are present on the palm of your hand:
- MI - means protection against abrasion;
- MA - such products provide vibration protection;
- MP - the product is protected from cuts and punctures.
Foreign models differ in different markings. In this case, the English letter denotes the protection class. There are such designations:
- A - speaks of abrasion resistance;
- B - indicates resistance to cuts;
- C - speaks of resistance to mechanical rupture;
- D - confirms puncture resistance.
A number is located near the letter, which indicates the level of operation. In addition to the listed characteristics, the quality of gloves depends on the following parameters:
- anatomical shape;
- the use of breathable environmentally friendly materials;
- elasticity;
- lack of seams;
- the presence of cuffs.
Applications
There are many areas of human activity that use harsh chemicals, and each of them uses protective gloves that are resistant to acids and alkalis. Let us name the industries in which such personal protective equipment is especially widely used.
KShchS gloves are used in the chemical industry, medicine, in the production and repair of cars.
Pharmaceuticals
During the development and manufacture of drugs, laboratory technicians are constantly exposed to chemicals, and some of them can harm unprotected skin.
Automotive industry
The process of working in this area assumes inevitable contact with oils, fats and some acids: for example, the electrolyte contains sulfuric acid, and therefore it is impossible to interact with such a substance without KSC 2 gloves.
Chemical industry
Chemical production and related areas are the main object, the needs of which are served by personal protective equipment. Every employee working in a harsh chemical environment must be fully equipped with overalls, and gloves are an integral part of a PPE kit.
Agricultural activities
The agricultural industry includes a whole range of works in which aggressive chemicals are involved in one way or another. For example:
- production of fertilizers for plants and their spraying;
- production and use of agents against insects, parasites and various diseases;
- the use of chemicals to control rodents that spoil crops and carry dangerous infections;
- disinfection of premises and equipment.
For the use of most tools, there are special devices - sprayers, pumps, etc., but when working with them, in any case, you must use personal protective equipment.
"Glove Factory" is the production and sale of work gloves made of latex, nitrile, split leather, nylon and cotton. If you want to buy gloves KShchS type 2 wholesale, leave a request on the website or by phone. We deliver orders across Chelyabinsk, the Urals and Kazakhstan.
Protective properties of work gloves. Notation. List.
Each protective property has a specific designation and is used for marking, in order to easily choose work gloves, it is enough to look at all the protective properties that correspond to a certain model and you will decide whether these gloves can fully protect your hands.
