Description
Technical field
The utility model is related to water pipe technology fields, specifically, being a kind of graphite modified aluminium-plastic pipe.
Background technology
Aluminium-plastic pipe (English name：Aluminum Plastic Tube) it is that a kind of indulged by centre welds aluminum pipe, inside and outside strata second
Alkene plastics and between layers utilize hot melt adhesive coextru-lamination made of novel pipeline.Polyethylene is a kind of nontoxic, free from extraneous odour
Plastics, there is good impact resistance, corrosion-resistant, anti-weather performance.The vertical weldering aluminium alloy of middle layer makes pipe have the resistance to of metal
Compressive Strength, impact resistance ability make pipe is flexible not rebound, and aluminum plastic composite pipe possesses the firm pressure resistance of metal tube and plastic tube is antiacid
The corrosion resistant two major features of alkali are the models of tubing of new generation.Aluminium-plastic pipe (aluminum plastic composite pipe) is on the market more popular one
Kind tubing, since its light, durable and easy for construction and aluminium-plastic pipe (aluminum plastic composite pipe) flexible is more suitable in house ornamentation
Middle use.
Aluminium-plastic pipe ectonexine is polythene material, and cleaning is nontoxic, smoothly.It can be used 50 years or more.Intermediate aluminium layer can
100% isolation gas infiltration, and make pipe while having the advantages that metal and plastic pipe, and eliminate respective disadvantage.
The advantage of aluminium-plastic pipe can mainly be summarized as following three aspects：
One, sanitation performance outstanding：Aluminium-plastic pipe ectonexine is Special polyethylene material, and cleaning is nontoxic.Most importantly
The middle layer of aluminium-plastic pipe is aluminium, it can not only be every light, and being capable of blocking oxygen.It is well known that the environment of the raw microorganism of evil
It is aerobic to must have light.The intermediate aluminium layer of aluminium-plastic pipe has just prevented the growth of microorganism and algae, this be full-plastic tube institute not
Can and.Full-plastic tube not only adds a large amount of antioxidant to prevent material degradation, antioxidant extraction from entering what pipeline was detained in itself
In water, it is be easy to cause water pollution, and because do not cause every the material of photoresist oxygen, the easily raw microorganism of evil in full-plastic tube
The secondary pollution of water quality
Two high and low temperature resistances are excellent：95 degree of temperature (50 years, IMPa), 110 degree of maximum operation (service) temperature, and aluminium is used for a long time
It is small to mould pipe coefficient of thermal expansion.It is suitable with the coefficient of thermal expansion of aluminium, only 1/6th of full-plastic tube.When by temperature change, become
Shape amount is smaller, and aluminium-plastic pipe is flexible coil pipe, and pipeline itself can digest certain deflection, will not cause the heat of pipe-line system
Bulging deformation.And the high and low temperature resistance of full-plastic tube is relatively poor.It is only 70 degree of (50 years, IMPa) highests that temperature, which is used for a long time, in PPR
95 degree of temperature in use.PPR pipe linear expansion coefficient is larger simultaneously, when being changed by external water temperature (hot and cold water), there is larger former deformation
Amount, since PPR pipe is rigid straight pipe, itself cannot digest deflection, therefore easily cause system flexural deformation even leak.
Three, service life is long：PE plastics used in aluminum plastic composite pipe, molecular chain structure (- CH2-CH2-) are in plastics
Relatively stable, and since aluminium-plastic pipe centre aluminium layer is isolated by ectonexine, outer layer plastic allows to be added and is enough to resist light, oxygen aging
Stabilizer without influence contact water internal layer wholesomeness, to reinforce its anti-aging property.
