Delicious crayfish to cool off the heat, but my hands are oily

Delicious crayfish to cool off the heat, but my hands are oily
.
It is currently the season of eating crayfish.
When eating crayfish, I don't know if you have noticed it.
Why do I eat crayfish with gloves, but the gloves are not broken, but my hands are still greasy
.
According to Chen Jian, a professor at the School of Chemistry and Chemical Engineering of Hunan University of Science and Technology, the gloves for eating crayfish are generally made of PE material, which is commonly known as polyethylene.
This is a kind of polymer material.
The molecular structure of PE material is a long chain.
It is very similar to the molecular structure of oil
.
In addition, in order to reduce environmental pollution, some of today's plastic products have been designed to be easily decomposed, so the plastic gloves look smooth, but there are also tiny holes, which is for the convenience of degradation
.
So, wearing gloves can't keep your hands clean, should you still use them directly in the future? No! Experts recommend wearing gloves
.
First of all, the oil is infiltrated in a small amount, and the effect is better than wearing no gloves.
More importantly, PE gloves can prevent bacteria from eating hands and nails
.
Zhao Jinyao, a researcher at the Hunan Provincial Institute of Quality Supervision and Inspection of Products, said that for PE gloves, the market supervision department will inspect the total migration amount, microorganisms, etc.
, but in terms of quality, there is no requirement for oil resistance
.
So how do you keep your hands from being so greasy when eating crayfish?
The following practices are for reference only:
The following practices are for reference only:First, change gloves frequently
.
Before the oil has had time to get into the gloves, quickly change to the next pair of gloves
.
But the disadvantage is that it costs gloves and is not environmentally friendly
.
First, change gloves frequently
.
The second is to wear several layers of gloves
.
According to the principle of oil penetration, if you do not want to change frequently, then wear several layers of gloves
.
The disadvantage is that the hands will be very hot, the oil has not yet entered the glove, the hand sweat has made the inner wall of your glove sticky, and it is not environmentally friendly
.
Third, wash your hands
.
Wash your hands while eating
.
The disadvantage is that it consumes too much water, and there is no pleasure in feasting
