itrogen Teflon screw profile itrogen Teflon screw profile Brief introduction Having superior release characteristics to the molded resin,plastic,silicone,all without sulfur plastic material.It is easy to demould within a limited draft angle,completely free use of release agent,to shorten the molding period 20%-25% can not generate scratches,dust is prevented due to electrostatic adsorption,also has strong resistance to acid and alkali corrosion function characteristics.Film thickness(HRC50--52),hardness of the coating thickness on the 0.01mm--0.015mm effect is better.immediately increase production efficiency after treatment,improve raw material reduced liquidity injection pressure and rate of fire.It is esp suitable for PVC,TPE,TPR,TPU,LCP,PU Ruanjiao die mold,insert,filling the mouth and other related department goods. Nitrogen teflon screw characteristics 1greatly reduce wear
2prolong the span life
3greatly reduce cost
4reduce the defective percentage The plastic,bakelite,silicone,pe foam,PVC,polypropylene with parting characteristics not sticky,easy demoulding,prevent the powder by electrostatic adsorption,abrasion resistance,no rust.
The reason of black spots in Plastic injection at present 1,long time heating.
2,the top of shoot material Friction overheating with Non-return.
3,the screw and barrel is enough straight. the introduction of screw and barrel After cooperation with Japan,Our company develops a new screw which has Multiple functions,such as wearresisting and corrosion resisting specific to extruder.there are many melt material in the market,but we ued the best corrosion resisting one with Japanese Surface treatment technologynitrogen Teflon and NPS to reaching The Desired Function of wear-resisting and corrosion resisting.The barrel material we use high speed fusion for production.the temperature of fusion is low,and engaging time is short,temperature control is accurate. wear resistance and corrosion resistant alloy melt in high strength steel pipe junction of the lining,form abrasion resistance and corrosion resistance with double alloy tube. NPS Coating The surface hardness of HV550 coating.
Alloy coating for chlorine gas and acid corrosion resistance performance of hydrochloric acid impregnated,solubility,than the electroless nickel coating is 5 times higher thanAcid resistance,but also excellent functional coating uniformity. Property:1.Excellent corrosion resistance,especially in chlorine glass and sea water.
2.The uniform skin film,complex shapes are uniform processing.
3.good for mould,screw and related department product processing machine which is high corrosive.
Corrosion resistance is(soaked in 50% of sulfuric acid in the water for 5 hours.And then the weight changes)
