Regarding "waterproof putty" and "waterproof putty", although there is only one word difference between the two, there is a lot of knowledge in the middle! Let's take a look at the article together!
It is true that "waterproof putty" has more gimmicks than "water-resistant putty": What is the use of "water-resistant putty", the wall is not soaked in water; "waterproof" is easy to understand, and it is easy to win the favor of the owner.
But did you know that this "waterproof putty" is a commercial trap at all, what is meant to mislead consumers, "waterproof putty" is a typical example!
Let me first talk about the correct term that is not easy to be used by profiteers, "water-resistant putty".
Where does the term "water-resistant putty" come from? Industry standards formulated from the country! "Building interior putty" (JG/T3049-1998) clearly stipulates which index of putty can be called "water-resistant putty" com" href="http://">coating online coatingol.
com .
So what are the characteristics of "water resistant putty" and why is it called "water resistant"? It should be said that "water resistance" is a name that combines the wisdom of experts and accurately expresses the characteristics of this putty.
The two major characteristics of "water-resistant putty"-"strongly sticky" and "extra long life" can all be reflected in the term "water-resistant".
The formula of "water-resistant putty" is completely different from ordinary putty.
Under normal circumstances, its bonding strength (a measure of whether it is strong or not) can reach 0.
Water vapor is everywhere, in the air, and also in the walls.
If putty is exposed to water, it will dissolve, how can it be strong when it sticks? How can the service life be extended?
What are the disadvantages of water-resistant putty? One is the high cost.
The second is that the water-resistant putty on the wall is not completely dry and there is alkali.
Come back, let's talk about the "waterproof putty" that started from the Mongols!
Many "experts" say that "waterproof putty" is "waterproof putty", the same-wrong! Wrong!
"Waterproof putty" is a term spread among the "people", and there is no written definition of what it is.
In the earliest days, "waterproof putty" referred to "imitation porcelain" (also called scraping porcelain, porcelain paste), and now many areas still say that "imitation porcelain" means "waterproof putty".
"Imitation porcelain" can indeed be "waterproof".
Many people think that "prevention" is a very good concept.
They don't know that "water can be drained but not blocked", but "prevention" is not enough, "prevention is impossible"! What should we do? Be "resistant"! "Water-resistant putty" does not block the entry and exit of water vapor.
