GX-195A high-temperature acid corrosion inhibitor uses high molecular weight, high boiling point organic polymer as raw material, does not contain N and other elements that interfere with the activity of the catalyst, and delays the corrosion of metals through two effects. On the one hand, the corrosion inhibitor forms an adsorption protective film on the surface of the metal material, which can effectively prevent naphthenic acid from coming into contact with the metal surface and reduce corrosion. On the other hand, some corrosion inhibitors directly interact with naphthenic acid to form naphthenic acid, which can establish adsorption equilibrium on the metal surface and isolate organic acids such as naphthenic acid from the metal surface to achieve the purpose of protecting the material.

First, you have to understand that your salary is ** than **? Most college students will say that of course they are the boss.
So where does the boss's money come from? Do you print it yourself? This is obviously a negative answer, the boss's money is the profit of the business.
Your salary** is based on the value you strive to create for the business. You have created a profit of 10,000 yuan for the boss, and you ask him for 2,000, maybe he will give it to you generously, if you only create a value of 1,000 yuan, how much do you think the boss will give you.
