Description
Technical field
The utility model relates to a kind of plastic water pipe, is specifically related to a kind of novel plastic hot-water line.
Background technique
Plastic tube is compared with pipelines such as traditional cast iron tube, Coating Steel Pipe, cement pipe, there is energy-saving material-saving, environmental protection, high-strength light, corrosion-resistant, inner wall smooth non-scaling, construction and the advantage such as maintenance is easy, long service life, be widely used in building industry, municipal administration, industry and the agriculture fields such as building water supply and drainage, town and country plumbing, gas, electric power and cable sheath, industrial fluids conveying, agricultural irrigation.Plastic pipe is an important branch in the numerous constituent elements of chemical building material, from using the difference classification of chemical materials, plastic pipe can be divided into polyethylene (PE) pipe, PVC＝polyvinyl chloride (PVC) pipe, polypropylene (PP) pipe, ABS pipe, polybutylene (PB) pipe etc.
Water pipe divides metal tube, composite pipe and plastic tube.Metal tube is mainly divided into copper tube and stainless steel waterpipe, and metal tube has safety, health, the various features such as durable, be the optimal water pipe of house ornamentation frock, but its price comparison is expensive.Composite pipe Typical Representative has aluminium-plastic pipe, but due to its problem of expanding with heat and contract with cold, is eliminated gradually.Plastic tube, due to safety, many reasons such as nontoxic, easy for installation, cheap, becomes the most frequently used water pipe of house ornamentation.Water pipe property indices is all tighter, is particularly used in above Drinking Water, needs pipeline to have nontoxic radiationless, can not contain the harmful matters such as heavy metal, and corrosion resistant ability will be got well, and the requirement such as will grow working life.
The moisture of water pipe supply is hot water and cold water and normal-temperature water etc., for hot-water line, just must its resistance to heat of body will get well, and also has heat insulating ability, antibiotic property well simultaneously.But simultaneously plastic tube all has the oxygen of oozing, and along with the rising of temperature, the oxygen feature of oozing of plastic tube is outstanding all the more.Especially for heat supply water pipe, this will cause the oxygen content in the hot water in pipeline to increase along with the rising of temperature.When hot water temperature is during higher than 40 ℃, oxygen infiltration amount can be greater than 0.1mg/ (L.day), now the metal device in water system is produced to serious corrosion.Therefore, the oxygen barrier of tubing is also needed to pay attention to some extent.
In numerous plastic tubes, because PP is nontoxic, tasteless, can in the boiling water of 100 ℃, soak indeformable, do not damage, common acid, alkali organic solvent work hardly to it, and its thermal conductivity is lower, therefore, are relatively applicable to hot-water line.But PP also has the oxygen of oozing, simultaneously self there is no self cleaning capacity, long-term use can become water pollution once again thing gathering with bacterial growth ground, serious threat health.
Therefore, in order to meet the demand in market, for socioeconomic development, also, in order to protect the healthy of people self, be necessary, develop a kind of resistant to elevated temperatures novel plastic hot-water line with self cleaning capacity (antibiotic cleaning ability) and oxygen resistance.
