The chemical industry is one of the basic industries of our national economy and, with the development of the times, has covered organic chemical raw materials, inorganic chemical raw materials, petroleum and products, chemical fibres, additives, chemicals for daily use, reagents, dyes, agricultural materials, inks, plastics and products, rubber and products, glass and products, alcohol, cement and other fields that are closely related to human life.
Every year, countless new people enter the industry, working day in and day out in chemical manufacturing and processing workshops.
Due to the nature of their work, workers in this industry are exposed to acids, alkalis and related chemical liquids, so factories equip their frontline staff with acid and alkali resistant safety shoes to ensure safety at work.
Acid and alkali resistant labor safety shoes are moulded and vulcanised and injection moulded with waterproof and acid and alkali resistant fabrics, with good acid and alkali resistance, and are suitable for protecting the feet from injury when they come into contact with acids and alkalis or when acid and alkali solutions are splashed on the feet.
Acid and alkali resistant labour protection shoes are a technological product, acid and alkali resistant labor protection shoes are suitable for workplaces where there is a certain concentration of acid and alkali, such as electroplaters, acid washers, electrolytic workers, liquid dispensers, chemical operators, etc.
Strong acids and alkalis are very corrosive, and their dehydrating and absorbent chemical properties can corrode skin tissue, and some emit irritating odours that can harm the eyes. Workers who often work in chemical plants, laboratories and other places where there is more contact with chemical materials are vulnerable to acid and alkali corrosion. It is highly recommended that purchasers of relevant factories purchase acid and alkali resistant labor protection shoes for their workers.
When purchasing, purchasers should choose regular channels and well-known brands, and purchase labor protection shoes with reliable quality and after-sales guarantee. The right choice will not only ensure the safety of workers, but will also reduce unnecessary problems and improve efficiency. At the same time, the purchaser should promptly test and verify the products purchased to ensure that the labour protection shoes sent to the workers are of a qualified standard.
There are many considerations for the maintenance of acid and alkali resistant footwear. Firstly, you should try to avoid contact with high temperature sharpeners that can damage the upper or sole of the shoe. Secondly, the acid and alkali liquid on the shoes should be rinsed with water after wearing and then dried to avoid long-term retention of the acid and alkali liquid on the upper and damage to the upper.
Guidelines for the use of acid and alkali resistant protective labor shoes include
1.Acid and alkali resistant labor protection shoes are suitable for general low concentration acid and alkali work scenarios, and can be exposed to acid and alkali rubber labor protection shoes with a concentration of less than 40%. If you are exposed to acid and alkali liquids with a concentration of more than 40% for a short period of time, you should rinse them off with clean water immediately after use to avoid shortening the use time.
2.Contact with high temperatures should be avoided to prevent sharp metal or sharp objects from piercing the upper or leakage from the sole.
3.Contact with strong oxidising acids such as nitric acid and chromic acid will cause brittleness, discolouration and early damage to the product due to strong oxidation. High concentrations of strong oxidising acids can even cause burn damage and affect the service life of safety shoes.
4.Latex industrial safety shoes are only suitable for weak acids, sulphuric acid, hydrochloric acid and various salts of low concentration, and should not be exposed to strong oxidising acids such as nitric acid.
5.General latex work labor protection shoes and agricultural labour protection shoes are only suitable for contacting general pollutants and cannot be used to contact acid and alkali work.
6.Prevent contact with petrol, motor oil, lubricants and various organic solvents when in use.
Acid and alkali resistant protective shoes are protective shoes with acid and alkali resistant properties for the protection of the feet against acid and alkali based chemicals. They are used in chemical (fertiliser), pharmaceutical (pesticide) and other industries where acids, alkalis and chemicals are involved. The damage caused by acids and bases to the human body is mainly in the form of skin burns, or stimulation of allergic reactions to the skin, causing folliculitis and systemic symptoms of poisoning.
Acid and alkali resistant rubber boots are protective footwear made from vulcanised rubber materials and can be divided into three types of boots: high boots, half boots and light boots. Acid and alkali resistant rubber boots have good acid and alkali resistance. Acid and alkali resistant plastic moulded boots are a kind of protective footwear made of PVC and other polymeric materials through moulding, which have good acid and alkali resistance.
Depending on the concentration of chemicals in the working environment, different materials are used for acid and alkali resistant protective footwear. If the concentration of chemicals in the working environment is low, the ground is dry and there is no obvious accumulation of liquid, acid and alkali resistant leather shoes can be used. If the working environment has a high concentration of chemicals and bases, the ground is wet or there is an obvious accumulation of liquid, you can choose acid and alkali resistant rubber boots or acid and alkali resistant plastic moulded boots. The key to the quality of acid and alkali resistant shoes is to use a waterproof leather upper with an acid and alkali resistant sole.
A good waterproof leather is both waterproof and breathable. Acid and alkali resistant leather shoes are generally made using gluing, injection and moulding processes, which have the advantage of a better waterproofing at the joint of the upper and sole. If the leather shoes are made with thread stitching, acid and alkali liquids can easily leak through the pinholes, so they should be reinforced by adding sticky strips around the thread stitching or sealing the pinholes with waterproof glue.
At present, acid and alkali resistant leather shoes mostly use glued rubber soles, which are cheaper and have better acid and alkali resistance. The disadvantage is that they are more bulky and less comfortable.
As for the injected leather shoes, the outsole is made of new polyurethane material, which has improved water resistance, better wear resistance and folding resistance, lightness and softness, and better comfort. The disadvantage is that they are less resistant to high temperatures and more expensive. Acid and alkali resistant leather shoes cannot be immersed in acid and alkali solutions for a longer period of time to prevent acid and alkali solutions from penetrating into the leather shoes and corroding the feet causing injury.
For acid and alkali resistant rubber boots and acid and alkali resistant plastic moulded boots, use tall boots, half boots and light boots depending on the degree of waterlogging in the environment. During use, avoid contact with high temperatures, sharp objects damaging the upper or sole of the boot causing leakage and affecting the protective function.
As plastic and rubber are easy to age and affect their service life, these products should be rinsed of acid and alkali liquids and dried with water after each wear, avoiding direct sunlight when drying.
When transporting and storing acid and alkali resistant shoes, avoid direct sunlight, rain and moisture, and do not put them together with acids, alkalis, oils and corrosive substances. Storage should be well ventilated and dry, and storage shelves should be more than 200mm from the ground and walls. Within 1 year from the date of production, the manufacturer should ensure that the rubber sole is not sprayed with sulphur. The shelf life of acid and alkali resistant plastic moulded boots (made of polyvinyl chloride) is 1 year.
It is easier for users to judge the quality of the appearance of acid and alkali resistant footwear, while the internal quality of the product should be checked by the factory inspection certificate, preferably by the inspection report issued by a third party inspection body recognised by the state government as the basis for judging the quality of the product.
