It is said that Xiong Haizi's body, whether it's stains on the pool or the stove, dirty shoes, or even a crayon-painted wall, will instantly become brand-new.
Is such a magical thing a "gift from the sky"?
Of course not!
In the era of great navigation, a top chemical student named Liwood Barton invented a kind of melamine foam, which was composed of melamine-formaldehyde-sodium bisulfite polymer.
This thing can effectively clean the ship. Taking advantage of this business opportunity, he started a ship cleaning company in partnership with a rich man.
But then someone invented the hull paint, and the business of the ship cleaning company plummeted.
1958 liwu sold melamine foam to Procter & Gamble, yes, it is a daily chemical giant.
They packaged this thing as a household cleaning artifact and changed it to Mr. Cleaning (also known as Kline Wipe, which is now the magic wipe).
I have to say, this thing really shines for the second time! People who have used it all say that the decontamination ability is 100%!
All this is attributed to its three-dimensional mesh porous structure with openings, and the rigid structure on the surface will play the role of fine sandpaper when rubbing. Use friction to remove stains on the surface of objects, and foam gaps can absorb stains.
The melamine bubble not only won the hearts of housewives, but also played a role in more fields. It is still sold in Amazon until now, and it has been selling well for 60 years!
However, Amazon mainly classifies it as a household category, which is limited to cleaning walls, bathtubs and shoes. And it is not classified as tableware cleaning!
In China, many families use it to wash pots and pans.
A treasure's business promotion is kitchen cleaning, dishwashing artifacts and so on. And greet bowls, plates and chopsticks directly.
To this end, we sent seven magic brushes for testing and found that six models of formaldehyde exceeded the standard, which was very serious! The one with the highest formaldehyde content actually reached 365 1mg/kg, even after washing, the formaldehyde content is still not low!
What is this? ! I work hard in in addition to formaldehyde every day, and as a result, the formaldehyde in kitchen cleaning utensils is seriously exceeding the standard!
Some people may ask, is formaldehyde insoluble in water? Why can't it be washed off?
This kind of magic eraser, from the process and structure, determines that it will continue to produce formaldehyde, no matter how many times it is washed, it will have formaldehyde, so it is not recommended for everyone to use it!
We bought it and tested it. The magic eraser with formaldehyde content of 279 mg/kg still has 267 mg/kg after washing for 5 times, as shown in the figure. )
Wei dad suggested:
Choose a rag, just ordinary cotton gauze in the supermarket.
In addition, do not scrub the non-stick pan and the non-stick pan liner of the rice cooker with scouring pad. Scouring pad contains emery, which is very sharp.
We reported the whole testing process to the relevant government departments, and Zhejiang Institute of Product Quality and Safety Testing issued the "Risk Announcement of Magic Eraser Defects" in June 2065438+2008.
I still hope to do something for the world with my own voice. Silence is very simple, there is nothing to bear, just sorry for yourself. Someone has to do this stupid thing. If I don't see anyone for a while, I will do it.
I hope this popular science can help you, and I hope you can share it to remind more people.
