ʻO nā resini kūikawā polyethylene (HDPE) kiʻekiʻe no ka paipu ʻāwili ʻia māhoe paia
High density polyethylene (HDPE) resins kūikawā no twin-wall corrugated pipe,
HDPE resin no ka paipu, ʻO ka resin HDPE no ka paipu ʻāwili ʻia māhoe paia,
ʻO ka polyethylene kiʻekiʻe (HDPE) resin kūikawā no ka paipu ʻāwili ʻia māhoe pā me ke anawaena nui.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.
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.ʻAʻole loa e pāpā ʻia ka lawe ʻana me nā mea ʻawaʻawa, corrosive a me ke ahi.

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.
