2) compressing: the skin blank level run through time delay delivery passes through in hydraulic press workbench plane, the descending compacting of top board, and the time is 17.25 seconds, and pressure is 10000kN;
3) running speed is recovered: the skin base suppressed is overrun in accumulator tank from flow and taken out of under the traction of flow restoration roller, recovers the production initial launch speed of 4 ms/min, enters subsequent processing.
The dynamic concora crush dish in two groups, described front and back respectively concora crush is by after last group of concora crush dish concora crush skin base slurry above skin base slurry, rear one group of concora crush dish concora crush skin base slurry again, imbricate 50-60mm during rear one group of concora crush dish concora crush and before and after the skin blank of last group of concora crush.
Present invention process flow process is simple, rationally, cost is low, compared with manufacturing regenerative leather, has following distinguishing feature with existing wet processing:
1. good product quality: the process of guarantor's slurry is carried out to skin blank, avoids active ingredient in skin blank with water loss; Flat-pressing dewatering peace is molded, makes fiber be in original polymeric species, improves the physical property of product.
2. energy-saving and environmental protection: owing to taking to protect slurry process and antivacuum water suction dehydration to skin blank, the chemical assistant in skin blank and fiber fully react, and not with water loss, the moisture of discharging in production is reusable, has saved water resource, has not produced pollution to environment.
3. applied range: the present invention both can utilize leather waste to produce corium fabric leather, also can utilize waste paper to produce footwear material inner bottom plating, can also mix rear production decorative panel or clad plate etc. by a certain percentage with leather waste and waste paper.
