The "sandwich method" used for glove box gloves usually refers to the use of multiple layers of gloves by the operator to improve experimental safety and protect the operator when operating the glove box. The specific steps of this method are as follows:
The first layer (skin contact): Firstly, the operator will wear a pair of gloves suitable for the operation task, which is usually a relatively soft, flexible, and thin pair of gloves to facilitate fine operations. This layer of gloves comes into direct contact with the skin, so it is necessary to ensure that they are comfortable enough and do not cause irritation to the skin.
Second layer (glove box gloves): After wearing the first layer of gloves, insert your hand into the glove box gloves, which are usually made of butyl rubber material and have certain protective functions, such as anti chemical penetration, high temperature resistance, or strong airtightness. This layer of gloves is an essential accessory during the experimental process.
Third layer (placed inside the glove box): Wear a durable pair of gloves on top of the gloves in the glove box. This layer of gloves is usually thicker than the first layer and can provide additional physical protection to prevent chemical splashing or mechanical damage to the second layer of gloves.
The "sandwich" usage method of glove box gloves can provide maximum protection for the gloves. When conducting experiments, the reaction vessel is often made of fragile glass material, and collisions during use may cause the glass to shatter, resulting in fragments. If appropriate protective measures are not taken, the gloves in the glove box are highly susceptible to damage, which can have a negative impact on the accuracy and progress of the experimental results.
In addition, when using glove box gloves, attention should also be paid to:
1: Operators should keep their nails short and smooth to reduce the risk of gloves being scratched.
2: Before entering the glove box, the operator should remove all hand accessories such as rings, watches, etc. to avoid scratching the gloves with these hard objects.
3: When conducting experimental operations, gloves should be avoided from coming into contact with sharp tools or fragments. When using, try to operate gently to avoid unnecessary pulling and friction, in order to reduce the risk of glove damage.
4: Select appropriate glove materials and sizes based on the specific needs of the experiment. During the operation, excessive stretching of the gloves should also be avoided, as this may lead to material fatigue and structural damage.
5: When gloves are not in use, an appropriate amount of talcum powder can be applied to their surface, which helps reduce friction, maintain the flexibility of the gloves, and extend their lifespan.
By following these precautions, the lifespan of glove box gloves can be effectively extended, ensuring the smooth progress of experiments.
