How to distinguish the quality of the leather cleaner
There are many different brands of leather cleaner on the market, but which one is better? Let ’s teach you how to distinguish the quality of the leather cleaner. Let’ s learn it.
1. Use PH test strip test with pH test strip
The pH value of pH = 1 ~ 14, neutral = 7, acidity = 1 ~ 7, alkaline = 7 ~ 14, the smaller the pH value, the more acidic the pH value, the larger the pH value, and the more alkaline.
Although the correct neutral value of the pH value table is = 7, the range of the neutral range can actually be extended to: pH = 6.5 ~ 7.5.
Put the pH value test strip into the leather cleaner to be tested for one second and take it out. According to the reaction color, the pH value of the pH of the acid and alkali.The more red, the more acidic, the more blue and black are alkaline.
Human or animals are slightly biased towards ester, that is, the pH value of human or animals = 5 ~ 7.5, and the dishwasply that does not hurt the hand in the advertisement, the pH value of the pH = 5 ~ 7.5.The pH value is greater than 7.5, and it will hurt the leather. If it is greater than 9, please do not use it.Of course, dont use it less than 4.
The pH value is greater than 7.5 or less than 4, which not only hurts the leather, but also hurts hands.
Qualified leather cleaner, the pH value of pH = 5 ~ 7.5.
PH test paper is generally available in teaching chemical stores.
Second, smell the smell, see volatility
If the smell of the leather cleaner is strong, it proves that it is highly volatile. Generally, it contains solvents and pollutes air. It will enter the human body with breathing, which is not conducive to human health and harmful to the human body.
The strong fragrance is generally the golden house Tibetan, which is the way to cover the smell with fragrance.Most chemical products have a bad smell, so add incense to cover up.Of course, although the spray -type leather cleaner is very convenient to use, users will also passively absorb, which is not conducive to human health.
Third, see if it is water, or oily
The water can be soluble in water, not toxicity, or low toxicity, and is generally environmentally friendly.Emorticia is generally water. If the alkali is too strong, it will hurt the skin.Oilly leather cleaner, which uses a solvent scheme, is generally more toxic than water and is not environmentally friendly.However, the newly inventing products, such as the leather cleaner of the leather mold, do not use the solvent scheme, and will not be toxic, so it is not in this column.
Fourth, the leather cleaner cannot contain a rubber agent
If the leather cleaner adopts a friction agent scheme, its cleaning principle is to remove the physical method of dirt by rubbing, just like sweeping the floor. If you do not pay attention, or the technology is not good, it is easy to grind the surface of the leather leather.However, if the dirt is too serious, it is too special, and there is no way to remove it. As long as the method is appropriate, it is better to grind the dirt and use the friction agent scheme better than using an internal structure of alkaline corrosion leather.
5. Look at the cleaning effect
Spray the leather cleaner on the surface of the leather. If it is clean, it must be very clean. This is the result of the chemical reaction. It has a strong corrosion force. Clean the leather leather with such a leather cleaner will look very very very very very very very very very very very very very very very very very very very very very likeClean, but the cost is to harm the leather, and if you use such a cleaner more than three times in the same part, the surface of the leather appears different.
Moreover, the cleaner from the pores into the dermis will destroy the internal structure of the leather and shorten the life of the leather. It will also harm the skin of the human skin. The pH value of the pH is generally impossible to = 5 ~ 7.5.Good leather cleaner, its cleaning power is generally not very strong, the cleaning speed is relatively slow, but it can also completely clean the leather dirt.
6. Practical test: See if the leather is happy
Practice is the only criterion for testing truth. After the leather is in contact with the leather cleaner, it will be shiny or dry immediately, and the leather will not be hard, and it can clean the dermis dirt. It must be a good product. Otherwisegoods.For leather, this is the most important test standard.
7. It can be degraded and has no pollution to the environment and meets environmental protection requirements.
To sum up, good leather cleaner generally meets the following conditions: 1. PH value of pH = 5 ~ 7.5; 2. No smell, no volatile; 3. Water properties; 4. No rubbing agent; 5. Moderate cleaning power;6. After contacting the leather, immediately shine or dry, the leather will not be hard, and it will clean the cleaning power of the dermis dirt, which will not pollute the environment and meet environmental protection requirements.
Among them, three points first, second, and third -class will affect human health, so we must pay great attention -health is more important than anything; one, four, five, and sixth equal to four points, you can judge whether the leather cleaner isIt is harmful; five or six or two points are practical tests; at the seventh point, the impact on the human environment can be judged.
