How to choose and buy leather care agent leather care agent why oil? - Music in Japan

Leather is soft, its root cause lies in leather making, the grease into the interior of the animal skins, forming oil film on the surface of the universal coverage within the skin fiber, in this way, the leather inside fiber friction between moving friction is equivalent to the oil molecules, so the leather is very soft, its principle and almost like a sponge.

but over time, the original into the inside of the leather grease under natural state and volatile slowly lost, or for other reasons make the oil film is destroyed, such as hydrolysis or high temperature environment under the influence of water, the oil film was damaged, oil volatilization losses. Therefore leather inside the oil film are destroyed or grease is lost, should be back to leather surface between internal fiber, high quality injection forming oil film of grease.





so leather care agent when the choose and buy, need to pay attention to what issues?

1, leather care agent must be fat

leather care agent containing oil, with the hand rub, a sense of oil, but not greasy, when the temperature of 450 ~ 750 degrees, with the help of the flammable, can burst into flames, so it can be burning method of inspection, namely the spray evenly on the toilet paper, a small amount of care agent in the mosquito-repellent incense on the shelf to ignite the toilet paper, burn to care agent, the nursing agent can burst into flames.

2, with a PH PH test

if leather care agent PH PH greater than 7, the alkaline condition, which penetrate into skin, damaged skin in the fiber on the surface of the original oil film, and wash away the skin grease, make the leather fibre interaction between the internal surface of the fiber bonding, friction, corrosion will leather fibre, thus leather harden, brittle, even cracking - - Alkaline substances harm the cause of the leather is here, use alkaline cleaner, clean the leather, penetrate into dermal internal alkaline substances, can damage the internal structure of genuine leather, especially the oil film on the surface of the fiber inside skin, make the leather hard, brittle, and even cracking. Therefore, in addition to the leather simulation oil leather cleaner, can't use nursing leather cleaner.

leather care agent qualified PH PH = 5 ~ 7, PH PH test paper stores in chemical teaching.


3, it is not easy to volatilize, no smell,

smell strong, prove that contains volatile components, mostly contain solvents. If the leather is not very dry, soon after the leather surface coated with care agent, also contain volatile solvent, nursing will enter the body through the respiratory system; When using leather, will enter the body via the pores of the human body, is not conducive to people's health. Also, the leather care agent containing volatile components, injection leather interior, due to its volatile will take away the original leather when injected into oil, make the leather become harder and more brittle.

aroma is generally & quot; Rib & quot; , the taste of most chemical products have bad smell, so to add incense.

4, with a suitable penetration and binding force

high quality leather care agent, can penetrate the leather equably inside the different parts of the fiber surface, and combined well with intradermal fiber, and the wax and the adhesion strength of the leather inside the fiber is poor, also because the candle burning low volatile, so the wax into the leather will soon be lost, because of its lost will take away the quantity of original oil at the same time, make the leather becomes harder and more brittle, and wax will jam MAO eye, thus pure wax leather is not suitable for nursing care.


5, water-based

leather care agent can be combined with water is the water, no water leather care agent general toxicity or low toxicity.

6, can be degraded, no pollution to the environment, accord with environmental protection requirement.
