A solid type fatty polyamide resin synthesized by a polycondensation of mainly the dimerized fatty acid and the alkylenepolyamines. The major applications is in the rotogravure printing inks . (a). Good solubility into various conventional industrial solvents. (b). Superior adhesion onto many kind of substrates. (c). Good wetting( dispersion,)of the pigments and dyestuffs. (d). Good resistance to water, oil and chemicals.. (e). Fast release of the solvent from the printed film.. (f). Smooth and hard film surface with high gloss. (g). Smooth and hard film surface with high gloss, which is suitable for over-printings.
Automatic nut tapping machine, nut tapping machine, tapping machine Hnt is suitable for hexagon, square, flange and nylon nut. Hnt can reach longer tapping stroke requirement while tapping longer or harder nuts. The operation panel is easy to understand and each spindle can be operated independent. Right or left tapping can be selected, tap life setting and adjust the tapping distance all can set up on the operation panel. Programmable language controller (plc) is used in the machine to monitor and control all tapping actions which can carry some functions including each spindle output counter is independent, operating automatically or manually, adjustable tapping speed, tapping error alarm of each spindle and motor overload alarm. Examination by current meter can detect tapping abnormal, jammed nuts during feeding or empty tapping, which can avoid tools get damage. The replacement of tools is simple and saving time. Magnetic chip filter maintain tapping oil is clean away the chips. Hnt is designed for safety consideration and qualified by ce.
