Burning a burned rubber gloves

When washing dishes, many people are accustomed to wearing a pair of rubber gloves to protect their hands. Recently, there are many users of microblogging on the microblogging material that is not a natural rubber rubber gloves, long-term use will release carcinogens. Some media have suggested that it is natural to verify that the rubber gloves are natural. If the gloves are exposed to heavy smoke and produce a lot of particles after burning, they are inferior gloves that contain recycled waste. Can you tell if the rubber gloves are good or bad? Is this method reliable? The reporter conducted an experiment.

Experimental Materials

Randomly purchased A, B, C, and D rubber gloves, lighters, and scissors from farmers' markets and large supermarkets.

Purpose

Does burning a fire really identify good or bad rubber gloves.

Experimental procedure

1. After unpacking, use a pair of scissors to cut a small piece of rubber sample on each pair of rubber gloves, and line them up according to the order of price to ignite 4 pairs of rubber gloves.

The 2.7-yuan glove A was bought from the farmers' market. It burned quickly when it touched the fire, emitting black smoke, emitting a pungent odor, and burning residues falling down, finally forming a granular solid; 12 yuan gloves B The situation after ignition was the same as that of glove A: it burned quickly, smoke was emitted, and many particles remained; the branded rubber gloves C purchased from a large supermarket were still in the same condition as the two pairs of gloves before the fire; after lighting 20 yuan of gloves D, The reporter found that the most expensive pair of gloves burned very fast, and produced a large amount of black smoke during the burning process, and dropped black colloidal residues.

Experimental results

4 pairs of gloves regardless of the brand and price, the state of combustion is basically the same - - rapid combustion, smoke, heavy particulates.

â—Ž expert statement

Burning a burned rubber glove can not tell the difference between good and bad

"Pure rubber burns relatively evenly, and the smoke is not so big. If you add back materials or other things, the molecular weight will be smaller. When it is burned, it may evaporate before it burns out. The smoke is relatively large." Industry insiders said that from 4 In the case of secondary gloves burning, it should be added, but this does not mean that these gloves are inferior. The reporter learned that in the production of rubber products, the state allows and encourages the addition of safe and harmless materials, which is the recycling of energy.

It is understood that judging whether rubber gloves are safe and hygienic depends on “burning” which cannot be distinguished, but whether the recycled materials used for reproduction are non-toxic and harmless. “The rubber gloves used for energy regeneration are mainly produced with back-feed comminution technology, and it is very difficult to kill germs. If you use inferior medical materials such as medical waste gloves that carry viruses and bacteria, make rubber gloves and wear such gloves. The potential threat to the human body is enormous when washing dishes and cooking."
