Nantong Bao Jian: do you need a protective suit in your working environment?

1n the modern industrial environment, workers often encounter flame, high temperature, molten metal, corrosive chemicals, low temperature, machining and some special hazards. For these hazards, special protective clothing is needed to protect the whole body. Protective clothing, also known as work clothes, is divided into special work clothes and general work clothes. 1t is made of cotton cloth or chemical fiber fabric, suitable for general workplaces without special requirements. According to the needs of the working environment, special work clothes include dust-proof and anti-virus clothes, anti chemical pollution clothes, anti heat and fire-resistant clothes, anti radiation clothes, anti-static clothes, etc< 1. Dust proof and gas proof clothes are all full body protective work clothes< The dust-proof clothing is suitable for dust operation. 1t is generally composed of hood or headband from head to shoulder, upper and lower garments, and the cuffs, trouser cuffs and hem are tightened. 1t is made of breathable fabric with dense texture and smooth surface2. There are two types of anti-virus clothing: airtight and breathable. Airtight type is a kind of air supply type protective clothing, which is made of impermeable materials and consists of headgear and clothes connected up and down. The overall structure is airtight. Clean air is sent in from the top of the head and discharged from the exhaust valves set at the cuffs, trousers and other parts. A certain positive pressure is maintained in the clothing to form a comfortable microclimate for the wearer. 1t is suitable for places with serious pollution hazards it is made of special breathable fabrics such as breathable anti-virus clothing fiber activated carbon. The cuffs and trouser cuffs are tightly tied, which can prevent the harm of certain poisonous gas and smoke. 1t is suitable for wearing in places with less pollution2. Anti chemical pollution clothing anti chemical pollution clothing includes anti acid and alkali clothing, anti oil clothing and so on. There are many kinds, materials and uses of anti chemical pollution clothing 1. Rubber acid and alkali resistant clothing Rubber acid and alkali resistant clothing is made of rubber cloth with rubber content more than 60% and stabilizer added in refining, and the material is airtight. The styles include work clothes, suspenders, reverse dressing, aprons, sleeves, etc. 1t is suitable for strong acid and alkali corrosion; Prevent acid and alkali splashing operation2. The plastic work clothes are made of PVC film and airtight. The styles include work clothes, reverse dressing, apron, etc. 1t is suitable for the operation of mild acid-base corrosion, water resistance, oil resistance and low concentration poison resistance, and is not resistant to high temperature and solvent< 3. Acid proof silk work clothes are made of chemically treated tussah silk and chemical fiber fabrics, and the materials are breathable. The styles include work clothes, coats, etc. 1t is suitable for the operation of anti acid mist corrosion, good acid resistance and air permeability, and has a certain ability of anti alkali and anti oil< 4. Synthetic fiber work clothes synthetic fiber work clothes are made of synthetic fiber fabrics such as polyester, polypropylene and chloro fiber, and they are also made of work clothes and coats. 1t is suitable for low concentration of acid and alkali corrosion, poor permeability< 1t is made of raw wool, which has good air permeability. 1t is suitable for preventing the corrosion of low concentration acid solution and acid mist. 1t has the ability of adsorption and penetration of acid solution, and has the function of heat insulation and cold resistance 6. Oil proof work clothes they are made of vulcanized synthetic rubber, polyurethane cloth and fluorine-containing resin fiber, which can prevent oil and water. Synthetic rubber oil resistant clothing can resist organic solvents, polyurethane oil resistant clothing can also resist organic deep agent, styles include work clothes, trousers and aprons, sleeves and so on< 3. Heat proof and fireproof work clothes are suitable for high temperature, high heat and strong radiant heat workplace. The materials for making heat-resistant work clothes should have the properties of high heat efficiency, low thermal conductivity, flame retardancy and high surface reflectance. 1t is made of canvas, asbestos and aluminum film white canvas is made of cotton canvas and hemp canvas woven from natural plant fiber, which has the characteristics of heat insulation, splashing sparks, easy falling of molten matter, wear resistance, high breaking strength and good air permeability asbestos heat protective clothing is made of asbestos cloth containing a small amount of cotton fiber, which has a strong shielding efficiency against radiant heat, but asbestos is harmful to human body, so it should be careful not to inhale it into the body when using. Asbestos shin guards and aprons are commonly used by workers working in molten metal the aluminum film cloth heat protective clothing is made of aluminized fiber or aluminized fiber on the base cloth, which is suitable for smelting furnace repair, fire rescue and other extremely high temperature operations. The aluminum film is silvery white with high reflectivity. The lining has the function of heat insulation, aging resistance and fire resistance, but the air permeability is poor< 4. Other special work clothes 1. Cold proof clothing cold proof clothing has good heat preservation, small thermal conductivity and high heat absorption efficiency on the outer surface. 1t is generally filled with natural plant, animal fur, down or chemical fiber. Ordinary cotton and leather cold suits have good thermal insulation performance, while chemical fiber cold suits are light in weight, which are also popular among outdoor workers2. Waterproof clothing the waterproof clothing has a raincoat with adhesive tape, which is cut with waterproof adhesive tape and bonded with neoprene adhesive. 1t is divided into single and double-sided adhesive tape, including raincoat, poncho, etc. Suitable for operation in rainy days with spraying water; The water jacket is suitable for sewers, culverts, aquatic fishing and other wading operations; The aquatic clothing is resistant to seawater and sunlight, and is suitable for fishing, aquaculture and processing< 3. Radiation protective clothing radiation protective clothing can be divided into radiation protective clothing and microwave protective clothing (1) radiation protective clothing should be used for personnel exposed to radiation to prevent the hazards caused by external radiation and radioactive dust pollution. According to the nature and dose of radiation, there are the following types: 1. white cloth protective clothing, made of bleached fine cloth, is the basic protective clothing for entering the radioactive operation area, which has the characteristics of low radioactive permeability, less absorption, air permeability, pollution and easy cleaning
