ʻO nā resina HDPE no ka paipu ʻāwili ʻia māhoe paia,
HDPE QHE16A, HDPE QHE16B,

Loaʻa i ka papa paipu HDPE ka mahele ākea a bimodal paha o ke kaumaha molekala.Loaʻa iā ia ke kūpaʻa creep ikaika a me ke kaulike maikaʻi o ka rigidity a me ka paʻakikī.He lōʻihi loa a he haʻahaʻa haʻahaʻa i ka wā e hana ʻia ai.ʻO nā paipu i hana ʻia me ka hoʻohana ʻana i kēia resin he ikaika maikaʻi, rigidity a me ka hopena hopena a me ka waiwai maikaʻi o SCG a me RCP.

Pono e mālama ʻia ka resin i loko o kahi waihona maloʻo a maloʻo a mamao i ke ahi a me ka lā pololei.ʻAʻole pono e hoʻahu ʻia ma ka lewa ākea.I ka wā o ka halihali ʻana, ʻaʻole pono e ʻike ʻia ka mea i ka lā ikaika a i ʻole ka ua a ʻaʻole pono e lawe pū ʻia me ke one, lepo, metala ʻōpala, lanahu a aniani paha.Kaʻahele pū me

ʻO nā mea ʻawaʻawa, ʻino a me nā mea hiki ke puhi ʻia ua pāpā loa ʻia.

Hiki ke hoʻohana ʻia ka pae paipu HDPE i ka hana ʻana i nā paipu kaomi, e like me nā paipu wai kaomi, nā paipu wahie a me nā paipu ʻoihana ʻē aʻe.Hiki ke hoʻohana ʻia no ka hana ʻana i nā paipu paʻa ʻole e like me nā paipu ʻāwili paʻa pālua, nā paipu hollow-wall, nā paipu silicon-core, nā paipu irrigation mahiʻai a me nā paipu hui aluminika.Eia kekahi, ma o ka reactive extrusion (silane cross-linking), hiki ke hoʻohana ʻia no ka hana ʻana i nā paipu polyethylene crosslinked (PEX) no ka hoʻolako ʻana i ka wai anuanu a me ka wai wela.

kiʻekiʻe kiʻekiʻe polyethylene (HDPE) resins kūikawā no ka māhoe-pā corrugated paipu me ka nui anawaena.Hōʻike nā hualoaʻa i nā resins kūikawā, i kapa ʻia ʻo QHE16A/B i kēlā me kēia, he modulus kulou ma luna o 1150 MPa, ikaika hoʻoheheʻe ma luna o 1.60 MPa a me ka manawa oxidation-induction ma kahi o 100 min.Loaʻa i nā papa ʻelua o nā resins ka hana maikaʻi a hoʻokō i nā koi no ka hana ʻana i ka paipu corrugated twin-wall i nā ʻoihana kūloko.
