Leather Chemical New Product Environmental Friendly Liming Agent Section Reduces Pollution

After many years of painstaking efforts, Xinxiang sainty calcium Industry Co., Ltd. in Henan province has tried to replace the tradition with a new product of anionic surfactants, high purity and high activity calcium hydroxide.

In the process of products, the ordinary lime leaching process has been generally successful.

The raw materials are slaughtered, peeled and slaughtered after being slaughtered, skinned and slaughtered. After being treated with antiseptic (salt / preservatives), they are pported to tanneries to start their manufacturing process.

Depilation and Liming (unhairingandliming): this stage is very important and a difficult process.

There is a very decisive factor in the process of dealing with the condition of the skin itself.

After the hair removal and soaking, the raw skins and grey skins are first added with sodium sulfide and liming auxiliaries, and a certain amount of hydrated lime is added to destroy the hair, so that the lime is evenly permeated and the skin is moderately expanded, so as to open the collagen fiber (Collagenfiber) of the skin and emulsify the natural animal fat of the raw skin to facilitate the subsequent tanning process.

After the hair removal and soaking, the skin is grey skin (grey skin). It must be split (split) and split into flour and coconut skin.

Instead of the traditional lime process, the special product of leather, which is used as a Liming Agent, has the characteristics of uniform expansion, strong permeability, fast speed, energy saving and environmental protection.

The dosage of lime is reduced by more than 2/3 compared with the traditional process, and the time of soaking is shortened by more than 1/3. It saves manpower, material and electricity and reduces production cost.

The improvement of this process is a revolution in the traditional leather leach process, which will surely create good economic and social benefits for leather making enterprises.
