Abstract
The utility model relates to the technical field of gas pipelines, in particular to a double-layer PE gas pipe with a termite-proof protection layer. The double-layer PE gas pipe comprises a gas pipeline, which is of a double-layer structure formed by a conveying inner layer serving as a conveying pipe and an anticorrosion outer layer resistant to termite corrosion, wherein the anticorrosion outer layer can be stripped from the conveying inner layer under the action of an external force. A certain adhering force is generated between the conveying inner layer and the anticorrosion outer layer, so that the two layers can be tightly adhered to each other without slipping or separating from each other, and meanwhile during installing, the anticorrosion outer layer at necessary parts can be stripped without damaging the conveying pipe of the inner layer, so that compared with a single-layer PE gas pipe, the double-layer PE gas pipe has the advantages of termite resistance, scratching resistance, safety and convenience in connection and the like, and the safety and reliability of the installation and use of the gas pipeline can be effectively improved.
Description
Technical field
The utility model relates to technology of gas pipeline field, more specifically, relates to a kind of double-deck PE fuel tube with termite-proof protective layer.
Background technique
PE fuel tube has that long service life, chemical resistance are strong, simple and reliable, the aspect advantage such as tightness good, good toughness, energy efficient, pipeline overall cost are low of constructing, on combustion gas is carried, obtain more and more a large amount of application, some areas are the first-selection using PE pipeline as town gas pipe.
But, the difficulties that PE fuel tube also exists some to solve when widely applying.As everyone knows, gas pipeline requires very high to Safety performance, yet because PE material hardness is lower, can be made by the erosion of termite moth that pipeline is damaged even to be gnawed through, thereby causes gas leakage; Due to characteristic easily scratch of surface in the process of transportation and laying of PE pipeline material itself, also bring hidden trouble to the safe handling of PE pipeline on the other hand.In addition, PE pipeline, when adopting electric smelting to connect, need be processed pipe surface, and process bothers relatively.
Model utility content
The technical problems to be solved in the utility model be for the deficiencies in the prior art, provide a kind of can be termite-proof, the double-deck PE fuel tube of scratch resistant, connection safe ready.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A double-deck PE fuel tube with termite-proof protective layer, comprises gas pipeline, and by carrying, internal layer and corrosion protection are outer forms double layer construction to described gas pipeline, and described corrosion protection skin can be peeled off mutually with carrying internal layer under the effect of external force.Carrying between internal layer and corrosion protection skin can close adhesion and can not slide or separated, can the corrosion protection skin of desired area be peeled off by external force when mounted simultaneously and does not damage conveying internal layer.
Further preferred scheme, in the above-mentioned double-deck PE fuel tube with termite-proof protective layer, the peeling strength between described conveying internal layer and corrosion protection skin is between 4.1-5N/mm.
Preferred scheme further, in the above-mentioned double-deck PE fuel tube with termite-proof protective layer, the peeling strength between described conveying internal layer and corrosion protection skin is 4.5N/mm.
Preferred scheme further, in the above-mentioned double-deck PE fuel tube with termite-proof protective layer, described conveying internal layer is made by one or more materials of PE80, PE100, PE100-RC.
Preferred scheme further, in the above-mentioned double-deck PE fuel tube with termite-proof protective layer, the outer field thickness of described corrosion protection is between 4.5-5.5mm.Preferably, Thickness is 5 mm.
Preferred scheme further, in the above-mentioned double-deck PE fuel tube with termite-proof protective layer, the outer composite bed for matrix resin interpolation modified additive of described corrosion protection.
Compared with prior art, the beneficial effect of technical solutions of the utility model is:
The gas pipeline that the utlity model has the double-deck PE fuel tube of termite-proof protective layer adopts double layer construction; by termite-proof and strippable corrosion protection is outer, form with conveying internal layer; compare with individual layer PE fuel tube and there is termite-proof, scratch resistant, be connected the advantages such as safe ready, can effectively improve the safety reliability that gas pipeline is installed and used.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the utility model embodiment gas pipeline.
In figure, carry internal layer 1, corrosion protection skin 2.
Embodiment
Below in conjunction with accompanying drawing, describing embodiment of the present utility model in detail, is exemplary below by the embodiment who is described with reference to the drawings, and only for explaining the utility model, and can not be interpreted as restriction of the present utility model.For better explanation embodiment, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing some known configurations and explanation thereof may to omit be understandable.
In Fig. 1; the utility model discloses a kind of double-deck PE fuel tube with termite-proof protective layer; comprise gas pipeline; this gas pipeline forms double layer construction by the corrosion protection outer 2 of the conveying internal layer 1 as delivery pipe and the erosion of termite-proof moth, and corrosion protection skin 2 can be peeled off mutually with carrying internal layer 1 under the effect of external force.Carry between internal layer 1 and corrosion protection skin 2 and have certain adhesive force owing to having, can guarantee can close adhesion between two-layer and can not slide or separated, can the corrosion protection skin 2 of desired area be peeled off by external force when mounted simultaneously and does not damage the delivery pipe of carrying internal layer 1.Carry internal layer 1 to be made by one or more materials of PE80, PE100, PE100-RC.And corrosion protection outer 2 is the composite bed of matrix resin interpolation modified additive.
Concrete, the peeling strength between conveying internal layer 1 and corrosion protection skin 2 is between 4.1-5N/mm.Better effects, normally peeling strength is 4.5N/mm.The thickness of corrosion protection skin 2 is between 4.5-5.5mm.Preferably, Thickness is 5 mm to effect.
In addition, the base resin in corrosion protection skin 2 is one or more in homo-polypropylene (PP-H), atactic copolymerized polypropene (PP-R), block copolymerization polypropylene (PP-B), PVC＝polyvinyl chloride (PVC-U), chlorinated polynvinyl chloride (CPVC) (PVC-C), polyethylene, polybutylene (PB), ABS.Modified additive contains one or more in nucleator, adhesive force modifier, light stabilizer, PVC auxiliary agent and look mother.Modified additive accounts for 5 ~ 40% of the outer 2 material gross weights of corrosion protection, and it comprises following component, by the percentage of the outer 2 material gross weights of corrosion protection:
Nucleator 0 ~ 10%, adhesive force modifier 0 ~ 10%, light stabilizer 0 ~ 5%, PVC auxiliary agent 0 ~ 40%, look mother 0.5 ~ 5%.
