Embodiment 1

[0016] 1. Open the outlet hand valve (1) of the slicing bin (13).

[0017] 2. Start the metering scale (2), open the slice inlet pneumatic slide valve (3), and the slices will fall into the mixer (4). When the metered slice volume is 1000Kg, close the slice inlet pneumatic slide valve (3).

[0018] 1. Manually add 4Kg of transparent softener (cadmium stearate) and 0.15Kg of dispersant (white oil) through feeding ports (5) and (6).

[0019] 2. After starting the mixer (7) for 12 minutes, stop stirring and open the electric valve (8) at the outlet of the mixer.

[0020] 3. Open the slice outlet pneumatic slide valve (9), send the evenly mixed slices to the packaging line (10), and pack them into 25Kg / bag.

[0021] 4. After packing, start the nitrogen inlet and outlet valves (11) and (12) to purge and replace the system.

Abstract

A process for preparing the modified nylon-6 chips (dedicated for fishing net) features that the nylon-6 chips are sufficiently mixed with transparent softening agent and disperser in dual-screw mixer to uniformly disperse the transparent softening agen on the surface of chips.

Description

technical field [0001] The invention relates to a production method of nylon 6 modified chips (special material for fishing nets). Background technique [0002] Nylon 6 monofilament used in the fishing net industry must have good transparency and softness in addition to certain mechanical properties such as tensile strength. Because the soft monofilament is easy to weave the net, the net knot is firm, and the mesh is not easy to deform; more importantly, the fishing net made of soft silk can make it difficult for the swimming fish entering the net to escape, which is conducive to improving the fishing rate. Fishing nets with good transparency are not easy to be found and escaped by fish and shrimp during the fishing process, which is also conducive to improving the fishing rate. At present, domestic manufacturers mainly rely on imported special materials for fishing nets from Japan, South Korea and other countries to produce high-quality nylon 6 fishing nets, which cost the...
