Anti-acid silk work is performed using chemically treated tussah silk and chemical fiber silk fabrics, making the material breathable. There are overalls, big coats, etc. It is suitable for operation against acid mist corrosion, good acid resistance and air permeability, and a certain ability to prevent alkali and oil.

4. Synthetic workwear

Synthetic fiber workwear is made of synthetic fiber fabrics such as polyester, polypropylene, and Kevlar, and there are overalls and styles. It is suitable for operation against low-concentration acid-alkali corrosion and poor penetration resistance.

5. Wool acid suit

The wool is acid-resisting and is made of raw wool. The material has good air permeability. It is suitable for preventing the corrosion of low concentration acid mist, has the ability to absorb and penetrate the acid, and has the effect of insulating and protecting the cold.

6. Anti-oil work clothes

Anti-oil work clothes are made of synthetic rubber which is made by vulcanization. It is made of polyurethane cloth and made of fluorine-containing resin fibers. It is both oil-repellent and waterproof. Synthetic rubber oil-proof clothing can be resistant to organic solvents, polyurethane oil-proof clothing can also prevent organic deep-agent, styles have overalls, bib pants and aprons, sleeves and so on.

Third, heat and fire protection work clothes

Heat-resistant work clothes are suitable for workplaces with high temperature, high heat and strong radiant heat. The heat-resistant work clothes must be made of materials that have high radiation heat resistance, low thermal conductivity, flame retardancy, and high surface reflectivity. It is made of canvas, asbestos, and aluminum foil.

The white canvas is made of cotton canvas and hemp canvas made from natural plant fibers. It has the characteristics of heat insulation, splashing of Mars and molten material, easy to drop, abrasion resistance, high tear strength, and good air permeability.

Asbestos heat-prevention taking asbestos cloth containing a small amount of cotton fiber, has a strong blocking efficiency for radiant heat, but asbestos is harmful to the human body, and care must be taken not to inhale the body during use. Workers working in molten metal often use asbestos leg guards and aprons.

Aluminum film heat protection clothing is made of aluminum or aluminized fiber on the base cloth. It is suitable for extremely high temperature operations such as smelting furnace repair and fire rescue. The aluminum film is silver-white and has a high reflectivity. The inner lining functions as a heat insulating layer and is resistant to aging and fire, but its air permeability is poor.

Fourth, other special work clothes

1. Winter clothes

Anti-cold clothing has a good thermal insulation, a small thermal conductivity, high external surface heat absorption efficiency, generally use natural plants, animal fur feathers or chemical fiber filler. Ordinary cotton, leather winter clothing insulation performance is good, and chemical fiber winter clothing light weight, but also popular among outdoor workers.

2. Waterproof clothing

Waterproof clothing with a cloth raincoat, cut with a waterproof adhesive tape, neoprene adhesive, single-sided double-sided adhesive, a raincoat, poncho and so on. It is suitable for spraying water and rainy days; watering garments are suitable for sewers, culverts, aquatic fishing and other wading operations; aquatic products are resistant to seawater and sunlight, suitable for aquatic fishing, aquaculture and other operations.

3. Radiation suit

Radiation suits are divided into radiation protection suits and anti-microwave suits.

(1) Radiation protection suits are used for personnel exposed to radioactivity to prevent the hazards of external radiation and radioactive dust particles. According to the nature and dose of radiation, there are the following types:

1 The white cloth is made of bleached cloth. It is a basic protective clothing that enters into the radioactive operation area. It has the characteristics of low radioactivity transmission, low suction, air permeability, and easy cleaning.

2 Non-woven protective clothing is disposable clothing that is suitable for use under low energy radiation.

3 Plastic protection Polyethylene or vinyl chloride film is welded by high frequency. It is an additional protective clothing covering the basic protective cover outside the basic protective clothing. It is resistant to a certain concentration of acid and alkali and oil, and is often used for maintenance or salvage. operation.

4 Lead-containing protection is made of lead-containing rubber or plastic and is suitable for personnel exposed to X and gamma rays.

(2) The principle of shielding and absorption of microwave protective clothing, made of metal cloth or metal plated cloth, etc., which attenuates or eliminates the electromagnetic quantity acting on the human body, can prevent the electromagnetic radiation of high-power radar and similar places from being harmful to the human body. Physiological effects.

4. Conductive protective clothing

Conductive protective clothing with anti-static clothing and equal pressure equalization service two.

(1) Anti-static clothing is used to generate static electricity, which can eliminate clothes and human body. One type is made of wire cloth, including copper wire, aluminum wire, etc. The function is to form a strong electric field around the conductive fiber when it comes in contact with the charged body, and the corona discharge occurs, so that the static electricity is neutralized and the conductive fiber becomes more Fine, anti-static effect is very good; the other with anti-static agent dipping fiber fabrics, such as polyester, polyester-cotton cloth and other systems.

(2) Equipotential pressure equalization clothing is made of wire, and it is an essential safety product for high-voltage operation. The current production of uniform pressure service is limited to the live work of 220kV or less. The surface resistivity of the pressure service suit is no more than 10Ω from head to toe, and surface oxidation and wire breakage are avoided during use.
