    "Rubber aging" is a general term for all the performance degradation preserved in the long-term use of rubber products, and it cannot be used to explain itself.

    "sticky" because the rubber undergoes an oxidation reaction in the presence of oxygen.

    The result is hydroxyl group, carboxyl group.

    Equipolar groups increase. These polar groups are the reason why things are sticky. In layman's terms, it is equivalent to becoming a self-adhesive.

    Finish. In addition, the term "rubber" now tends not to refer exclusively to natural rubber.

    Therefore, it can be said that not all rubber products are prone to stickiness. Natural rubber is easy to get sticky because it contains a lot of carbon-carbon double bonds, which are more prone to oxidation reactions.

    If it becomes sticky after contact with solvents, it is due to the dissolution of components in the rubber that are not involved in cross-linking. Rubber products are generally cross-linked, and the cross-linked part is the main part of the rubber, which only swells and does not dissolve under the action of solvents. If this is the case, it is often non-stick again after the solvent has dried.

    The surface of rubber products will become slimy after a long time because the oxidation reaction of rubber occurs in the presence of oxygen, and the result is an increase in polar groups such as hydroxyl and carboxyl groups. These polar groups are the reason why things are sticky.

    1. Nail washing and wiping.

    You can choose a cotton pad or a thick point of paper to pick up the nail wash, choose the rubber to melt and stick to the ground, wipe the range, and you can solve it.

    2. Vinegar washing.

    Apply vinegar to the top and then wipe it with paper, so that it is clean.

    3. Slippery powder.

    Apply a release agent or slip powder to relieve stickiness; Hypochlorous acid rinse table.

    4. Wind oil essence.

    You can rub the wind oil essence, and it will fall off after a while, try it.

    5. Alcohol. Dip the cloth in alcohol, wipe repeatedly, if the gum has hardened, first rub it warmly, soften the gum, and then alcohol can be removed.

    6. Foaming.

    Polysiloxane-polyalkoxy ether copolymer is called foaming, soluble silicone oil, which is first decomposed from chlorosilane into polysiloxane, and then condensed with polyether synthesis. Yellow or brown buttery viscous transparent liquid. Just wipe it down.

    There are two main reasons why erasers are sticky:

    1. Plasticizer.

    and other small molecule group analysis.

    2. The surface is oxidized or degraded by light.

    "sticky" because the rubber undergoes an oxidation reaction in the presence of oxygen.

    The result is hydroxyl group, carboxyl group.

    Equipolar groups increase. These polar groups are the reason why things are sticky. In layman's terms, it is equivalent to becoming a self-adhesive.

    Precautions for using erasers.

    If you make a mistake by using the eraser directly on the contaminated area, it will stain the paper. Children should also be taught to clean up the debris left behind by using erasers. Collect the eraser scraps and put them in the trash bin without getting the debris on the floor.

    The predecessor of the eraser was bread, and in the 16th century, when the pencil was born, there was no eraser, and people used the white part of the bread to erase the pencil notes.

    Nowadays, there are many types of erasers, with different colors and shapes, and some with different fragrances, which are deeply loved by children. However, the purpose of using an eraser is to wipe the typos clean, so when choosing an eraser, you should choose an eraser that is easy to use and saves time and effort.

    After many children enter the upper grades of primary school, they still erase their homework and books "beyond recognition" because of the use of erasers, and even erase the entire page "rotten". This seemingly small problem is actually related to the fact that parents do not correctly guide their children to use erasers in the early days.

    Use an eraser to erase a typo that needs to be corrected, but it must be cleaned up. It is better to choose the right eraser according to the type of pen.

    Summary. 1. How to clean up the sticky rubber surface.

    1. Nail polish remover. Take nail polish remover with a paper towel and wipe it in a small area. 2. Vinegar.

    Apply with vinegar and wipe with paper after drying. 3. Talc. Applying a release agent or talcum powder to the surface can reduce surface stickiness.

    4. Alcohol. Dip a cloth in a little alcohol and wipe it repeatedly. If the gum hardens, rub it with warm water to soften the gum and then use alcohol.

    What should I do if rubber products are sticky?

    1. How to clean up the sticky rubber surface 1. Nail polish remover. Take nail polish remover with a paper towel and wipe it in a small area. 2. Vinegar.

    Apply with vinegar and wipe with paper after drying. 3. Talc. Applying a release agent or talcum powder to the surface can reduce surface stickiness.

    4. Alcohol. Dip a cloth in a little alcohol and wipe it repeatedly. If the gum hardens, rub it with warm water to soften the gum and then use alcohol.

    1. Flame retardant will not catch fire at high temperature, and the floor will not burn after being immersed in gasoline. Cigarette butts that fall on the floor will not cause disaster. The floor will not be damaged, and alcohol can be used to clean e-liquid traces.

    2. Once the environmental protection product is produced, used or disposed of, it is non-toxic, tasteless, dust-free and volatile substances harmful to human health in the whole process. 3. Good elasticity, comfortable feet, comfortable flooring, and glasses and cups are not easy to break when they fall on them. Wear-resistant, non-slip, waterproof, moisture-proof, easy to clean, outdoor use is not afraid of rain, snow, and sun.

    In a humid environment, there will be no stagnant water underground. Cleaning is simple and convenient, and the dust is usually wiped clean with a clean water mop. Oil stains can be treated with a cloth or brush dipped in detergent, soap, etc., and then cleaned with a mop.

    4. Recyclable materials can be reused to effectively protect social resources. Rubber flooring is a comprehensive environmental protection material, non-toxic and harmless, no three wastes in the production process, no mold, no bacteria, no gas or harmful substances are released during use, there is good thermal insulation performance, it can be used indoors in winter, and it is cool in summer.

    I hope mine can help you and have a great day!

    The stickiness is due to the oxidation reaction of rubber in the presence of oxygen, and as a result, polar groups such as hydroxyl and carboxyl groups increase. These polar groups are the reason why things are sticky.

    Why do rubber products become as if they have melted after a long time, and the surface is sticky?

    Dear, it's a pleasure to serve you. <>

    The main reason for the melting of rubber products is the aging of rubber after being used for a long time or being placed for a long time; "Stickiness" is due to the oxidation reaction of rubber in the presence of oxygen, and as a result, polar groups such as hydroxyl and carboxyl groups increase. These polar groups are the reason why things are sticky. In layman's terms, it is equivalent to becoming a self-adhesive.
