Kiʻekiʻe kiʻekiʻe Polyethylene Paipu Papa
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.
Palapala noi
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.
