HDPE Pipe Has Obvious Advantages

2018-11-15

HDPE Pipe má vynikající chemickou stabilitu, odolnost proti stárnutí a odolnost proti praskání v životním prostředí. Dvouvrstvý měch z HDPE z něj je ohebná trubka.

Strong ability to resist foreign pressure

Vnější stěna je prstencová vlnitá struktura, která výrazně zvyšuje tuhost prstence trubky, čímž se zvyšuje odolnost trubky vůči zatížení půdy. V tomto provedení má HDPE Pipe oproti jiným trubkám zřejmé výhody.

Low project cost

Za stejných podmínek zatížení, HDPE dvouvrstvé vlnité trubky potřebují pouze tenkou stěnu může splňovat požadavky

Proto, ve srovnání se stejnými vlastnostmi materiálu z pevné stěny trubky, může ušetřit asi polovinu surovin, takže HDPE potrubí je také nižší náklady, což je další prominentní rys potrubí.

Konstrukční pohodlí

Vzhledem k tomu, HDPE dvojité stěny vlnité trubky lehké, manipulace a připojení jsou velmi pohodlné, takže konstrukce rychlá, snadná údržba, v těsném harmonogramu a špatné stavební podmínky, výhody jeho více zřejmé.

dlouhotrvající

Při nepřítomnosti slunečního svitu UV, životnost trubek HDPE až 50 let.

High density polyethylene, the English name for the "High Density Polyethylene", referred to as "HDPE". HDPE is a high degree of crystallinity, non-polar 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 non-hygroscopic and has good water vapor resistance and can be used for packaging applications. HDPE has good electrical properties, especially dielectric dielectric strength, making it very suitable for wire and cable. Medium to high molecular weight grade has excellent impact resistance, at room temperature even in the -40F low temperature are so.

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 polymer is not hygroscopic and has good water vapor 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 potrubí je tradiční ocelové trubky, PVC pitné vody náhradní výrobky.

HDPE pipe must bear a certain pressure, usually to use a large molecular weight, mechanical properties of better PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficulty in connection, and is not suitable as a material for water supply pressure pipes. However, due to its higher health indicators, LDPE, especially LLDPE resin has become a common material for the production of drinking water pipes. LDPE, LLDPE resin melt viscosity is small, good mobility, easy processing, and thus its melt index selection range is also wide, usually MI between 0.3-3g / 10min.
