The invention discloses a high-barrier composite film which comprises a film body, wherein the film body is formed by sequentially compounding an LDPE (Low-Density Polyethylene) outer layer, a PVDC (Polyvinyl Dichloride) middle layer and an LDPE inner layer. The high-barrier composite film is produced by the following steps of: respectively adding LDPE, PVDC and LDPE resin particles into three extruder hoppers of a composite film blow molding unit in the proportion of 36 percent:28 percent:36 percent; heating to a melting state by an extruder melting section; collecting into an upper die head, a middle die head and a lower die head of a composite die head for compounding; and blow-molding, cooling for moulding, drawing and carrying out corona treatment to obtain a finished film product with the thickness of 0.09-0.18mm. The invention has the advantages that three materials are compounded into a three-layer film by three extruders of the composite film blow molding unit, the materials with ...

Thermoplastic oil delivery pipeline system

Номер: CN0101994485A
Автор: Zhang Chunjian
Принадлежит:

The invention discloses a thermoplastic oil delivery pipeline system, which comprises a thermoplastic delivery pipeline, a submersible pump cable and a stainless steel wire rope. The submersible pump cable and the stainless steel wire rope are respectively arranged on an outer wall of the thermoplastic delivery pipeline through an integrated layer; and the submersible pump cable and the stainless steel wire rope are mutually parallel to an axis of the thermoplastic delivery pipeline. The defects of higher friction even mutual winding among the delivery pipeline, the submersible pump cable and the stainless steel wire rope are overcome, the construction difficulty and workload are reduced, a phenomenon that the submersible pump cable is easy to snap is effectively reduced in the process of singly using the thermoplastic delivery pipeline, the submersible pump cable and the stainless steel wire rope, and the service life of the delivery pipeline system is prolonged.

Принадлежит:

The invention discloses a low-temperature reinforced nylon composite tube used for an automobile, comprising a lining tube, a braid layer and an outer protective layer. The braid layer is coated at the periphery of the lining tube; the outer protective layer is coated at the periphery of the braid layer; and the weight ratio of the lining tube, the braid layer and the outer protective layer is 48.5:0.5:51. The product has the characteristics of excellent low temperature resistance and heat resistance, pressure resistance, high mechanical strength, strong flame retardance and wear resistance, low cost and the like. The low-temperature reinforced nylon composite tube used for the automobile is made of special nylon composite material with low-temperature resistance and high pressure resistance by advanced continuous dynamic vacuum shaping technique. The modification of material improves the water absorption of the nylon composite tube, improves the size stability of the product and low-temperature ...
