Embodiment 1
[0039] Present embodiment one follows the following procedures successively:
[0040] 1. Crush the raw materials
[0041] Use a pulverizer to crush the broken skins of the raw materials into skin corners of a certain size, usually below 5×5 mm, so as to facilitate the operation of process 2.
[0042] 2. Production
[0043] Pour the crushed fine fragments into a bucket-shaped container, and inject 1 times the water; stir through the mixer for 8 minutes to make the fine fragments absorb water, so as to increase the adhesion with the adhesive; then add the common adhesive epoxy resin, through Stir evenly to make the wet fine fragments and adhesive evenly attached; place a layer of nylon at the bottom of the wooden frame mold, pour the stirred fine fragments into the wooden frame mold and spread a layer of nylon on the fine fragments, and then press water Press on the machine for 8 minutes to form a regenerated leather sheet at one time; take out the wooden frame mold from the w...
Embodiment 2
[0053] The second embodiment is basically the same as the first embodiment above, the difference lies in the tablet making process. The concrete process of present embodiment two sheet-making operation is:
[0054] Pour the fine fragments into a bucket-shaped container and inject 2 times the water; stir for 10 minutes with a mixer to make the fine fragments absorb water to increase the adhesion to the adhesive; then add the common adhesive epoxy resin and stir evenly Make the wet fine fragments and adhesive adhere evenly; add the first layer of polyester to the bottom of the wooden frame mold, pour the stirred fine fragments into the wooden frame mold and spread them flat, and then lay the second layer of carbon fiber on the fine fragments, and then lay the second layer of carbon fiber on the second layer Pour the stirred fine fragments on the carbon fiber and pave them flat, then lay a third layer of polyester on top of the fine fragments, and then put the wooden frame mold o...
Embodiment 3
[0056] The third embodiment is basically the same as the first embodiment above, the difference lies in the tablet making process. The concrete process of present embodiment three film-making operations is:
[0057] Pour the crushed fine fragments into a bucket-shaped container, and inject 0.5 times the water; stir for 5 minutes through a mixer to make the fine fragments absorb water, so as to increase the adhesion with the adhesive; then add the commonly used adhesive epoxy resin, Stir evenly to make the wet fine fragments and the adhesive evenly attached; pour the stirred fine fragments into the wooden frame mold and pave them flat, lay a layer of soft metal mesh on the fine fragments, and then pour the stirred fine fragments into the soft metal mesh. The fragments are paved, and then the wooden frame mold is placed on the water press for 5 minutes for compaction to form a recycled leather sheet at one time; the wooden frame mold is taken out from the water press, and the shee...
