Embodiment 1

[0022] Example 1, such as figure 1 Shown:

[0023] An improved clean production process for Tan sheepskin, comprising the following steps:

[0024] (1) Pre-treatment: Trim the burrs on the corners of the Tan sheepskin, remove the burrs on the corners of the Tan sheepskin, then scrape and degrease the flesh of the Tan sheepskin, soak in salt water for 2h-3h;

[0025] (2) Tissue fixation: Mix glutaraldehyde, glycerin, phenol and polyethylene glycol according to the concentration ratio of 25:53:20:2 under ultrasonic vibration at 35°C to 45°C to adjust the pH of the solution The value is 9.0-11.0, and the Tan sheepskin is soaked in the mixed solution for 12h-15h;

[0026] (3) Tanning treatment: Tan sheepskin is tanned with a drum, the temperature of the tanning treatment is 32-35°C, the time is 3.5-3.8h, the pH of the tanning treatment solution is 5.5-6.0, and the compound tanning agent in the tanning treatment solution is The amount of 10-20g / L is added; the leather tanning pr...

Abstract

The invention relates to the technical field of Tibet lamb skin clean production, in particular to an improved Tibet lamb skin clean production technology which comprises the following steps: (1) pretreatment; (2) tissue fixation; (3) tanning treatment; (4) bleaching treatment; (5)dying treatment; and (6) liquid waste treatment. According to the improved Tibet lamb skin clean production technology, the tanning working procedure and the liquid waste treatment working procedure can effectively ensure the production quality of the Tibet lamb skin and the utilizing efficiency of chromium; the tanning extract and chromium react to form chromate flavone type polymer precipitate to facilitate chromate filtration and cleaning to production liquid waste and recycling of the liquid waste, so that the cleaning efficiency and the recycling efficiency of the liquid waste are improved to realize a better cleaning environmental protection effect, resource waste is reduced, and higher popularization and application value is realized.

Description

technical field [0001] The invention relates to the technical field of clean production of Tan sheepskin, in particular to an improved clean production process of Tan sheepskin. Background technique [0002] Tan sheepskin is one of my country's traditional export native products. It is well-known at home and abroad for its strong leather board, light weight and warmth, smooth and beautiful fur, and curved wave pattern. It is a unique animal husbandry resource in Ningxia. [0003] However, the existing Tan sheepskin production process still has the following problems in the specific use process: on the one hand, because the chrome tanning method is mainly used in the Tan sheepskin tanning process, the chrome tanning waste liquid produced cannot be effectively treated and pollutes the environment; On the other hand, a large amount of waste liquid containing high-concentration dyes produced in the dyeing process cannot be effectively treated, pollutes the environment, and the u...
