HDPE Pipe Has Obvious Advantages

2018-11-15

HDPE cev ima odlično kemijsko stabilnost, preprečuje staranje in odpornost proti razpokam v okolju. Dvostenski meh HDPE iz njega je prožna cev.

Močna sposobnost upiranja tujim pritiskom

The outer wall is an annular corrugated structure, which greatly increases the ring stiffness of the pipe, thus enhancing the resistance of the pipe to the soil load. In this performance, HDPE Pipe has obvious advantages compared with other pipe.

Nizki stroški projekta

Pod enakimi pogoji obremenitve valovita cev HDPE z dvojno steno potrebuje le tanko steno, ki lahko izpolni zahteve

The Therefore, compared with the same material specifications of the solid wall tube, can save about half of the raw materials, so HDPE Pipe is also lower cost, which is another prominent feature of the pipe.

Priročnost gradnje

As the HDPE double-wall corrugated tube light weight, handling and connection are very convenient, so the construction of fast, easy maintenance work, in the tight schedule and poor construction conditions, the advantages of its more obvious.

dolgotrajno

In the absence of sunshine UV conditions, HDPE Pipe life of up to 50 years.

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 je termoplastični poliolefin, pridobljen s kopolimerizacijo etilena. Čeprav je bil HDPE uveden leta 1956, vendar ta plastika še ni dosegla zrele ravni. To skupno gradivo tudi nenehno razvija svoje nove namene in trge. Termoplastična smola. Videz prvotnega HDPE je bil mlečno bel, v rahlem prerezu je bil do določene mere prosojen. PE ima odlično odpornost na večino značilnosti življenjskih in industrijskih kemikalij. Nekatere vrste kemikalij lahko povzročijo kemično korozijo, HDPE cevi, kot so jedki oksidanti (koncentrirana dušikova kislina), aromatski ogljikovodiki (ksilen) in halogenirani ogljikovodiki (ogljikov tetraklorid). Polimer ni higroskopen in ima dobro odpornost na vodno paro

PE lahko izdelamo s široko paleto različnih načinov obdelave. Vključno z ekstrudiranjem, kot je ekstrudiranje pločevine, ekstrudiranje filma, ekstrudiranje cevi ali profila, oblikovanje s pihanjem, brizganje in rotacijsko oblikovanje.

HDPE cev je tradicionalna jeklena cev, izdelki za nadomestitev cevi za pitno vodo iz PVC.

HDPE cev mora nositi določen tlak, običajno za uporabo z veliko molekulsko maso, mehanske lastnosti boljše PE smole, kot je HDPE smola. LDPE smola ima nizko natezno trdnost, slabo tlačno odpornost, slabo togost, slabo dimenzijsko stabilnost med oblikovanjem in težave pri povezovanju ter ni primerna kot material za tlačne cevi za oskrbo z vodo. Vendar pa je LDPE, zlasti LLDPE smola, zaradi svojih višjih zdravstvenih kazalcev postal pogost material za proizvodnjo cevi za pitno vodo. Viskoznost taline smole LDPE, LLDPE je majhna, dobra mobilnost, enostavna obdelava, zato je tudi njen izbor indeksa taline širok, običajno MI med 0,3-3g / 10min.
