Leather care agent selection method Leather goods company to buy leather care agent method large exposure Most people who use leather goods pay attention to the cleaning of leather goods. Sometimes they are entangled in not buying good care agents, and sometimes the beauty of the leather goods is destroyed by improper use of the care agent. Let us take a look at how to buy leather care agents? wallet manufacturers
1.
The leather care agent must be grease. A leather care agent containing oil and fat, when oiled by hand, has a feeling of oil, but is not greasy. When the temperature reaches between 450 and 750 degrees, it can be ignited and burned with the help of flammable materials, so it can be tested by combustion method. Spray a small amount of care agent evenly on the toilet paper, put it on the mosquito-repellent rack, ignite the toilet paper first, and burn it to the care agent, then the care agent can be burned.purse manufacturers
2.
Detect with pH value of pH. If the pH value of the leather care agent is greater than 7, it is alkaline, it penetrates into the skin, destroys the original oil film between the fibers on the inner surface of the skin, and washes off the oil inside the skin to make the inner surface of the fiber between the fibers The fibers stick to each other, the frictional force becomes larger, and the leather fibers are corroded, so the leather becomes hard, brittle, and even cracked. The reason why alkaline substances damage the dermis is here, that is, using an alkaline cleaner to clean the dermis and infiltrate. The alkaline matter inside the dermis destroys the internal structure of the dermis, especially the oil film on the surface of the intradermal fibers, making the dermis hard, brittle, and even cracked. Therefore, it is not possible to care for the dermis with a detergent in addition to the skin-improving oil dermatological cleaner. The pH value of the leather care agent is between 5 and 7. pH pH test strips are
3, not easy to volatilize, no smell. The odor is strong, and it is proved to contain volatile components, and most of them contain solvents. If the leather is not very dry, it will dry quickly after applying the care agent on the surface of the leather. It also means that it contains volatile solvents, which will enter the human body through the respiratory system during the treatment. When using the leather, it will enter the human body through the pores of the human body, which is not conducive to Human health. In addition, when the leather care agent containing the volatile component is injected into the inside of the dermis, the volatilization also removes the original fat injected during the tanning, making the leather harder and more brittle. The aroma is generally “Golden House,� and most of the chemical products have an unpleasant smell, so it is necessary to add a scent. available at general chemical teaching stores.www.wallet-manufacturers.com

It has suitable penetration and bonding force. The high-quality leather care agent can evenly penetrate into the fiber surface of various parts of the leather, and is well combined with the intradermal fibers. The bonding strength between the wax and the inner fibers of the dermis is poor, and the wax is low in ignition and is easily
volatilized. Therefore, the wax will soon be lost in the leather. Because it is lost, it will also take away the original grease in the leather, making the leather harder and more brittle, and the wax will block the eye, so the pure wax is not suitable. Used to care the dermis. 5, water. Leather care agents can be combined with water to be aqueous, and aqueous leather care agents are generally non-toxic or very toxic.

The treated leather has the following characteristics:
a, soft, treated leather, because the oil film between the skin surface of the skin is refurbished and repaired, the bond between the fibers in the skin is removed, so that the friction between the fibers on the surface of the fiber is approximately equal to the oil molecules. Friction, so the dermis is very soft; b, the leather has a moisturizing feeling; c, fullness; d. Waterproof, after leather care, the water on the surface of the obliquely placed leather will not stay, and the water will not easily penetrate into the leather; e, mechanical strength such as tensile strength, tear strength, grain cracking strength, etc. can be greatly increased, and can also increase the elongation of the dermis; f, does not close the dermis of the dermis, has little effect on the water vapor permeability, almost no effect. 7, can be degraded, no pollution to the environment, in line with environmental requirements. Leather care oil leather care agent – Mepi Wang leather care agent can meet the above requirements. But one-sided pursuit of surface glazing effect, the leather surface is like a wall, decorated like a mirror, not the care, but the decoration – this is closed ventilation pores, a bit like self-binding, is not conducive to human health .
