Technical field
The utility model is a kind of special equipment of producing the 3 D stereo grid screen with certain altitude that high molecular polymer forms through thermoplastic or mold pressing, is specifically related to a kind of special stretcher of plastics GSZ.
Background technology
GSZ is by polyethylene, polypropylene or high density polymer, the net material with square or rectangle of stretched formation, and difference of draw direction can be two kinds of simple tension and biaxial tensiones when making by it.It is punching on the sheet material of making through extruding, implements orientation stretching then under heating condition.The simple tension grid only stretches along the sheet material length direction and makes, and the biaxial tension grid then is to continue the grid of simple tension is made in the direction stretching vertical with its length again.Because the plastics GSZ macromolecule of polymer in the mill can rearrange orientation with heating extension process, has strengthened the connecting forces between strand, has reached the purpose that improves its intensity.Its percentage elongation has only 10%~15% of former sheet material.If in GSZ, add anti-aging materials such as carbon black, can make it have endurance quality such as acidproof, alkaline-resisting, corrosion-resistant and anti-aging preferably.
Two-way GSZ be with high molecular polymer by extruding, become after plate, the punch process more vertically, cross directional stretch forms.This material all has very big hot strength on vertical and horizontal, this structure equally also can provide the desirable locking system of bearing and spreading of a more efficiently power in soil, is adapted to the ground of the permanent carrying of large tracts of land.Unidirectional GSZ is to be pressed into thin plate again towards regular hole pattern by high molecular polymer through extruding, and longitudinal stretching forms then.Make macromolecule become the direct line sexual state netted globality structure of oblong that also formation is evenly distributed, node strength is high in this process, have quite high hot strength and stretch modulus.
At present, the stretching-machine that is used for unidirectional plastics GSZ stretching sheet material is five-roller stretcher, this equipment is the stretching that comes existing GSZ by five-roller stretcher speed difference each other to the stretching of sheet material, this stretching form stretches for the single-point single-line type, by intensity and the draw ratio of GSZ itself, mainly there is following shortcoming in the stretching of this form to the degree that stretches entirely:
1., because stretching sheet material is the single-point single-line type, stress was concentrated when sheet material stretched, and caused sheet material that internal stress is arranged, and caused sheet material stretching uneven thickness.
