Introduction: Introduction of glass fiber yarn or single direct rovings shares by 2000 or 4000 bore hole bushing drawn directly from continuous fibers. The main application for winding, pultrusion process as for UP, VE, EP. Typical products: pultruded rod, window frames, ladders, pipes, communication cables, tanks, woven roving and chemical resistance of the grille. Direct roving or single-end continuous roving (Pultrusion Roving, Filament Winding Roving, Weaving Roving), made directly from a 2000 tip bushing or a 4000 tip bushing, is primarily used in filament winding and pultrusion processes in polyester, vinylester or epoxy resin systems . Typical products are pultruded rod, window frames, ladders, pipe, telecommunication cables, tanks, woven roving and chemical resistant grating Features:. Features uniform tension, into the band Good Even Tension, excellent tapability resin impregnated fast speed, compatibility Excellent. Fast and Complete Wet-out hairiness, excellent wear resistance No Fuzz, good abrasion resistance and mechanical properties the packaging: Packaging transit CSL produced by direct yarn, single yarn group polyethylene plastic-coated, and then into trays or cartons. Each tray can be stacked 64 or 48 yarn groups, each roll weight 17kg. Cardboard boxes piled higher than 5 layer tray piled high no more than two layers. Direct roving from Zhongtian Junda, is wrapped in plastic bags, then packed in individual cardboard box or pallet. There are 64 or 48 doffs could be placed on one pallet, 17kg weight of one doff. Cardboard box can not be stacked higher than 5 layers , and pallet not higher than 2 layers Note (Remark):. 1 pallet size (L * W * H) (cm) Pallet dimension (length * width * height) (cm):. 112 * 112 * (94/118) 2. Yarn group size (L * W * H) (cm) Doff dimension (diameter * height) (cm): 26 * 26 Storage: Storage Product should be placed dry, cool place. If not, do not open the packaging to prevent moisture, affect use. Unless otherwise specified, it is recommended to store products in a cool, dry area. The products must remain in packaging material until just prior to their use. If these conditions are respected, the product should not undergo significant changes when stored for extended periods of time.
