HDPE pā pālua corrugated paipu maka mea,
HDPE no ka hana ʻana i ka paipu corrugated pā pālua, ʻO ke ʻano o ka resin HDPE i hoʻohana ʻia no ka paipu corrugated pā pālua,

HDPE pā pālua corrugated paipu maka mea

1. Hoʻohui ʻia o nā mea maka: ʻO nā mea maka o ka PE pālua-wall bellows maʻamau i haku ʻia me ka polyethylene, nā mea haku i hoʻonui ʻia a me nā puaʻa.Inā pulu ka mea maka, i mea e hoʻomaikaʻi ai i ka hana pono, hiki ke hoʻohui ʻia ka defoamer kūpono.

2, nā koi hana o nā mea maka: pehea e hana ai i ke kumu kūʻai haʻahaʻa, nā bellows kiʻekiʻe kiʻekiʻe, e hilinaʻi nui ʻia i ke koho ʻana o nā mea maka a me ka collocation formula.

ʻO nā koi maʻamau no ka hana ʻana o ka polyethylene (PE) e pili ana i ka melt flow rate (MFR), oxidation induction time (OIT) a me ka density.Hōʻike ka nui o ka kahe kahe o ka hehee i ka nui o ke kaumaha molekala.ʻO ka mea maʻamau, ʻoi aku ka maikaʻi o ka hoʻoheheʻe ʻana o ka melt flow rate i ka hana ʻana a me ka hana ʻana, a hiki ke hoʻomaikaʻi i ka pono hana.Eia naʻe, ʻaʻole hiki ke nui loa, ʻoi aku ka nui o ka hopena i ka paʻakikī o ke apo.He kūpono ke koho ma waena o 0.8-1.5g/10min(190 ℃, 5kg).Hoʻoholo ka manawa induction oxidation i ka manawa o ka pōʻino oxidation.No nā bellows e koi ana i 50 mau makahiki o ka hoʻohana ʻana, ʻo ka kāohi ʻana i ka manawa induction o ka oxidation o nā mea maka ke kī e hōʻoia i ke ola lawelawe o 50 mau makahiki.Ua ʻōlelo maopopo ʻia ma GB / T19472.1-2004 ʻo ka manawa induction oxidation o ka mea maka o ka bellows he ≥20min (200 ℃).No ka polyethylene kiʻekiʻe a me ke kiʻekiʻe, hiki ke hoʻoponopono ʻia kona mau waiwai ma ka hoʻololi ʻana i ka density.No ka mea, ʻike mākou hiki i ka polyethylene haʻahaʻa haʻahaʻa ke hoʻolōʻihi i kona manawa hiki ʻole.

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.
