Technical development of galvanized pin

Update: 2011-3-22
Along with the reciprocating screw, relative motion of each pin and a screw block for curve, when kneading screw gap generated when the axial pin by pin in the process of material exchange, a circle of rotary screw, screw spindle and the relative motion of the side cutting the material to produce screw and barrel in axial and the radial was cleared. This is a reciprocating mixing extruder thoroughly mixing, kneading and self-cleaning effect based. These pins as mixer a series of materials to achieve the redistribution of extrusion screw machine interrupt materials have a return, the process of material under continuous shear, orientation, cutting, folding, stretching. A part of the melt to recombine, part of the melt further segmentation in the groove of each L / D, to melt after four times of segmentation, therefore, why can the effective mixing of very short slenderness ratio and achieve the reciprocating melt extruder. And the inner surface of the machine barrel is swept through the thread, there is no dead end of the logistics, has a good self cleaning capacity, high transmission efficiency and stable and uniform material retention time and so on. Because it is relatively stable in the atmosphere, and the cost is low, so in the anti-corrosion of the fastener is widely used. The galvanizing process is the traditional electro galvanized, galvanized, zinc, and nearly 20 years to develop: mechanical plating, Dacromet coating technology. In a large number of zinc plating process, the anti-corrosion effect of the galvanized layer and the process itself is not contact, in the same service environment, the corrosion resistance of galvanized layer thickness determined by the. Therefore, we should choose the fastener surface galvanized processing, should be based on two principles: the thickness of the galvanized layer and economic. The thickness of the galvanized layer is determined mainly by the service environment, and the general indoor fastener is equal to the corrosion protection and decoration. At present, the zinc plating process is preferred. Outdoor fastener for relatively harsh service environment, galvanized with anticorrosive, hot-dip galvanized, zinc can choose and mechanical plating. It is mainly used for compound shaping extrusion of tire tread parts in tire production, and can also be used for other rubber products. According to the different parts of tire performance, can be made of different rubber material and formula of radial tire after the pin cold feed extruder with different specifications in the die extrusion composite of various specifications, bias tire, using a variety of tire composite extrusion, its performance is good, high quality standard. Because of the use of rubber material and formula of different raw materials, the cost is reduced, the production efficiency has been greatly improved.
