What are the polyethylene film sleeves?
0.4 thick polyethylene plastic film isolating layer, Beijing fixed no specific item, is paved with a layer of plastic cloth, can supplement the quota, labor costs by 0.5 yuan / square meters, according to the actual price included in the cost of materials.1.2 thick polyethylene geomembrane fixed: Materials 15 yuan / square meter, artificial 4 yuan / square meter.
Specification for polyethylene tape: its thickness * width * length, in fact, determines what thickness of adhesive tape to use.For example: in order to strengthen the level level of corrosion, corrosion thickness of 1.0mm; corrosion level reinforced, corrosion thickness of 1.4mm;According to the lapping mode with internal and external anticorrosive adhesive tape, tape thickness determination.
According to the construction mode of adhesive tape winding, determine the width of anticorrosive adhesive tape. Manual winding, do not use too wide tape, the construction of workers when the intensity is not easy to control, it is best not to exceed 150mm width; manual mechanical entanglementWinding (part of the simple mechanical and human coordination) visual conditions, but the maximum width should be 230mm; mechanical winding can be appropriate to relax the width of tape, but it is best not to exceed 300mm.Polyethylene film is a commonly used plastic film, because of its non-toxic, so a lot of food used for making packaging bags. Notice the difference between PVC and polyvinyl chloride (PVC). The simple way is to make the polyethylene film for ignition, and the non flammable is PVC film.A separation layer between a polyethylene film, a barrier layer, an intervening coil, and concrete or other protective layer. It is also considered a separate protective layer.
