guennewichtheimann safety protective equipment Germany guennewichthe model guennewichtheimann price

guennewichtheimann safety protective equipment acid and alkali resistant workwear is primarily used in the production, transfer, and handling of acids and other chemicals, cleaning and repair of chemical containers such as tanks, and disposal of chemical waste and hazardous substances. Personnel who are in prolonged contact with strong acids and other chemicals can effectively isolate harmful substances like strong acids and solvents from skin contact by wearing appropriate acid-resistant workwear. The "Standard for Equipment of Labor Protective Supplies (Trial)" issued by the State Economic and Trade Commission in 2007 stipulates that electroplaters, lead powder makers, picklers, electrolyzers, solution preparers, and chemical operators are typical jobs requiring the issuance of acid-resistant suits; workers in these roles should be equipped with acid-resistant workwear of different types and grades. Furthermore, for chemical enterprises, although chemical raw materials generally operate in closed pipelines and reaction tanks, appropriate acid-resistant suits should still be provided to personnel with a higher likelihood or frequency of contact with chemicals (such as feeding workers and maintenance staff). This ensures maximum protection of operator safety in case of leaks due to equipment or pipeline failures or operational errors.

guennewichtheimann safety protective equipment functions and applications

Acid and alkali resistant workwear is an essential part of protective clothing, along with fire-resistant chemical suits and heat-insulating protective clothing. It is worn by workers at sites with hazardous or corrosive chemicals to protect themselves from damage by chemical hazards or corrosive materials. To understand the function of acid and alkali resistant workwear, we start with the workers who wear it. Simply put, the function of acid and alkali resistant workwear is corrosion resistance and acid/alkali resistance. Acid and alkali resistant fabrics are mainly used to prevent harm to the human body from chemical agents such as acids and alkalis, prolonging the time it takes for acid liquid to penetrate from the garment surface to the skin, preventing acid liquid from adhering to the garment surface, ensuring minimal change in strength after acid erosion, and enabling the garment to withstand strong acid pressure. It is also essential equipment for maintaining the health of workers in the chemical industry. For non-breathable acid-resistant workwear, ventilation holes for sweat discharge and temperature regulation should be located under the armpits, on the back, and inside the hips to prevent external foreign objects or acid liquid from entering. Minimize unnecessary decorations such as straps and loops to avoid accumulation of acid liquid in seams or interference with work.

Acid and alkali resistant workwear fabric is mainly used to prevent harm to the human body from chemical agents such as acids and alkalis, prolonging the time it takes for acid liquid to penetrate from the garment surface to the skin, preventing acid liquid from adhering to the garment surface, ensuring minimal change in strength after acid erosion, and enabling the garment to withstand strong acid pressure. Acid and alkali resistant cotton fabrics are generally divided into non-breathable and breathable types. Non-breathable acid and alkali resistant fabrics generally include rubber, nylon, plastic, and composite materials; although safe, they are uncomfortable to wear. Breathable acid and alkali resistant fabrics generally include cotton and cotton-synthetic fiber blends, such as CVC, polyester-cotton, and cotton-nylon. Acid and alkali resistant workwear fabrics generally need to have characteristics such as acid resistance, abrasion resistance, high breaking strength, and strong puncture resistance. Among these characteristics, the requirement for acid and alkali resistance is the highest. The acid and alkali resistance reaches 97.5%, which is higher than the national acid resistance standard of 97%, meeting the requirements for acid and alkali resistant workwear.

guennewichtheimann safety protective equipment precautions

Acid and alkali resistant workwear must not come into direct contact with flames or molten materials. Before use, carefully inspect the garment for damage; if damaged, it is strictly prohibited to use. When using acid and alkali resistant workwear, ensure the hood fits tightly with the mask facepiece, and fasten the neck strap and large white buttons on the chest to ensure airtightness at the neck and chest. The waist belt must be tightened to reduce the "bellows effect" during movement. After each use, wash with clean water or a 0.5–8% sodium carbonate aqueous solution depending on the degree of soiling, then rinse with clean water, place in a cool and ventilated area, dry, iron, and package. To ensure the effectiveness of acid and alkali protection, it is strongly recommended to keep soaking and washing times as short as possible and to iron after washing. When folding fully sealed chemical protective suits, lay the hood opening upward on the ground. Fold back the hood, neck strap, and both sleeves, then fold the suit vertically, aligning left and right sides, with the toes of both boots facing outward. Place gloves in the middle, roll the boots bottom-to-bottom into a roll, and place horizontally into the fully sealed chemical protective suit packaging bag. During storage, fully sealed chemical protective suits must not be exposed to heat or sunlight, and must not come into contact with active chemicals or various oils.
