An end stripper that strips a polymer coating from flexible screen frame material, the end stripper including a table having a tabletop and ground engaging legs, an induction coil coupled to an induction power supply, a clamping assembly located proximate the tabletop and sized to receive a first end portion of flexible screen frame material therein. The induction coil positioned and shiftable to receive the first end portion of the flexible screen frame material therein and operable to heat the first end portion by induction thus softening a polymer coating of the flexible screen frame material. A first stripping jaw strips the polymer coating from the first end portion.

The disclosure provides a flushing process for removing polymer fouling from a reactor including a gas distributor proximal to the bottom thereof and an internal condenser proximal to the top thereof, the method including, for a first flushing time period, injecting a flushing solvent into the reactor and withdrawing the flushing solvent from a reactor outlet proximal to the internal condenser to induce an upward movement of flushing solvent, the withdrawn flushing solvent containing a first polymer content. After the first flushing time period is complete, for a second flushing time period, the process includes injecting a flushing solvent into the reactor and withdrawing the flushing solvent from a reactor outlet proximal to the gas distributor to induce a downward movement of flushing solvent, the withdrawn flushing solvent containing a second polymer content.

The invention is a system for drying, recycling, and washing off residual resin from 3D-printed objects. Some aspects of the invention include a system for recycling solvents used to clean the 3D-printed objects in a washing chamber. The recycling system may include one or more solvent reservoirs that store a solvent for cleaning residual 3D-printing material off of 3D-printed objects, a wash chamber adapted to clean the 3D-printed objects, and a solvent recycling module. The solvent recycling module receives a saturated solvent from the one or more solvent reservoirs, evaporates or condenses the saturated solvent to remove residual 3D-printing material from the saturated solvent, and returns clean solvent to the one or more solvent reservoirs of the system.

The invention is generally a system for drying, recycling, and washing off residual resin from 3D-printed objects. Exemplary systems may include a system for drying off residual resin from 3D-printed objects. The system may include a wash reservoir including a chamber for housing the 3D printed object and containing a wash solvent or liquid solvent adapted to at least partially remove residual residue present in the 3D printer object. Air exchange vents provided between a splash guard or a lid of the wash reservoir may be adapted to act as an air intake or an air exhaust. An airflow module in fluid communication with the air vents and the chamber may be adapted to create a positive or negative air pressure inside the wash reservoir for redirecting airflow to the chamber housing the 3D printed object, and blowing air out or into the chamber to dry the 3D-printed object.

The invention is generally a system for drying, recycling, and washing off residual resin from three-dimensionally (3D) printed objects. Exemplary systems may include a system for washing off residual printing material from a surface of a 3D-printed. In an exemplary embodiment, a chamber is adapted to receive the 3D-printed object and a printing material disruption module is adapted to disrupt a composition of residual printing material on a surface of the 3D-printed object. Additionally, a washing force module may be adapted to apply a washing force field to the 3D-printed object and wash off the residual printing material.

A cleaning agent composition contains a main material for the cleaning agent composition; and an amine compound which does not include an amino group located at an end of a molecular chain but includes an amino group located at a position other than the end of the molecular chain.
