HDPE Rør God Elasticitet, Høj Impact Resistance, Ikke-giftig

2018-11-15

HDPE tube

The reason is that the melt flow in the cylinder, the flow between the cylinder wall and the inner wall of the difference, when leaving the die, the whole melt and no resistance, the gap between the two becomes zero. It is the relative movement of the layers of the change, causing the mold at the melt flow of intense oscillation, leading to the occurrence of such phenomena!

Solution:

1, ekstra hjælpemidler: gerne organiske silicone tilsætningsstoffer (silicone plast additiver) eller Fu Fu polymer additiver (PPA).

2, kan den passende temperaturstigning også forbedre smelteflowet!

Squeeze HDPE pipe, and sometimes because of temperature, and sometimes because of the type of raw material problems and more or less patterns, but sometimes it is to increase the temperature, change the plastic model or how much. There have been tested on the membrane head of the air ring overhead, or that elevation.

3, vælg det sikrede HDPE rør først for at bestemme det relevante materiale. Tidligere var rørene til vandforsyning hovedsageligt støbejernsrør. Udenfor det store sandstøbegodsrør, indendørs brug af galvaniseret støbejernsrør, der kan opdeles i kold (elektrisk) galvaniseret og varmgalvaniseret to. Galvaniseret rør som vandrør, brugen af ​​nogle få år senere producerer røret en masse rust, udstrømningen af ​​gult vand, ikke kun forureningen af ​​sanitetsartikler, og blandet med ikke-glatte vægtelivsbakterier, rust forårsaget af høje niveauer af tungmetaller i vand, alvorlig skade på menneskers sundhed. Endnu vigtigere er udførelsen af ​​et sådant overlegen HDPE-rør, prisen er ikke dyr.

Drainage HDPE pipe is the traditional PVC, pig iron pipe drinking water pipe replacement products. Drainage pipe must be able to prohibit the inevitable pressure, usually choose the machine function is better, large molecular weight PE resin, such as HDPE resin, and LDPE resin pressure, tensile strength is low, poor steel, forming the proportion of poor stability when polished , And the connection problem, not suitable as a drainage pressure pipe material.

From the high temperature function, PE pipe with the temperature rise of its function to quickly reduce the use of temperature of ± 60 ° during which the general use of cold water for the main, mainly for the drainage pipe on the main road, which after the home Of the drainage pipe selection, will choose PPR pipe.

PE rør lys vægt, god elasticitet, høj slagfasthed, giftfri, billigere enhedspris, lav temperatur ydeevne er bedre, er nu kommunale byggeri, fast ejendom, fabrikker, vand conservancy byggeri og anden vandforsyning og dræning rørledning skal.

  HDPE is a thermoplastic polyolefin produced by copolymerization of ethylene. Although HDPE was introduced in 1956, but this plastic has not yet reached a mature level. This common material is also constantly developing its new uses and markets. The thermoplastic resin. The appearance of the original HDPE was milky white, in a slight cross-section was a certain degree of translucent. PE has excellent resistance to most of the characteristics of life and industrial chemicals. Certain types of chemicals can produce chemical corrosion, such as corrosive oxidants (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is not hygroscopic and has good resistance

PE can be manufactured with a wide range of different processing methods. Including extrusion such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and rotomoulding.

HDPE rør er det traditionelle stålrør, PVC drikkevandspip erstatningsprodukter.

The roughness coefficient of the HDPE pipe is between 0.009 and 0.01, which is much smaller than the roughness coefficient of the reinforced concrete pipe (0.013-0.014). It can be seen that compared with the reinforced concrete pipe with the same diameter, In the traffic will be greater. For the municipal drainage works, through the application of HDPE off, can effectively increase the amount of emissions, thereby reducing the construction of sewage pumping stations, reducing the cost of urban sewage treatment.

HDPE rør er et fleksibelt rør, der i sin grænseflade normalt bruges i en fleksibel forbindelse, har en god tætningsydelse og har en stærk evne til at tilpasse sig ujævne afviklingsrørledninger, er anti-lækage meget stærk. Sammenlignet med de rene betonrør, der anvendes i de traditionelle kommunale afløbsarbejder, er HDPE-røret fleksibelt på materialet og fundamentet, og det kan spille en effektiv underjordisk forurening på grund af dens gode forsegling og gode anti-lækage.


HDPE pipe and the traditional reinforced concrete pipe is different from the use of high-density polyethylene inert materials, so a variety of chemical have a strong corrosion resistance, so in high acid, high alkali or sewage discharge has a good effect The In the underground use, HDPE pipe can be used for more than 50 years, while the reinforced concrete pipe is susceptible to corrosion in the soil, usually in the service life of about 20 years. It can be seen, compared with the traditional reinforced concrete pipe, HDPE has a longer or useful life.
