HDPE resin no ka hana paipu
HDPE resin no ka hana paipu,
HDPE resin no na paipu, Papa paipu resin HDPE, Mea hoʻolako resin HDPE,
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.
Nā māka a me ka waiwai maʻamau
ʻO ka HDPE he crystallinity kiʻekiʻe, non-polar thermoplastic resin.ʻO ka hiʻohiʻona o ka HDPE mua he keʻokeʻo waiū, kahi pae o ka translucency ma ka ʻāpana lahilahi.He kūpaʻa maikaʻi ka PE i ka hapa nui o nā kemika home a me nā ʻoihana.Hiki i kekahi mau ʻano kemika ke hoʻopōʻino kemika, e like me nā mea hoʻoheheʻe ʻino (concentrated nitric acid), aromatic hydrocarbons (xylene) a me ka halogenated hydrocarbons (carbon tetrachloride).ʻAʻole hygroscopic ka polymer a loaʻa iā ia ke kūpaʻa mahu maikaʻi, hiki ke hoʻohana ʻia no nā kumu hoʻopili.He waiwai uila maikaʻi loa ka HDPE, ʻoi aku ka ikaika dielectric kiʻekiʻe o ka insulation, i kūpono loa ia no ka uea a me ke kaula.ʻOi aku ka maikaʻi o ke kūpaʻa ʻana o nā papa kaumaha molekala waena a me ke kiʻekiʻe ma ka lumi wela a hiki i nā mahana haʻahaʻa e like me -40F.
Nā mea e pono ai ka nānā ʻana i ka hoʻohana ʻana i ka paipu HDPE
1, ka waiho ʻana i waho o ka lewa, kahi e loaʻa ai ka lā o ka lā, pono ia e hana i nā hana hoʻomalu.
2. ʻO ka pipeline wai wai HDPE kanu ʻia, hiki ke hoʻokomo ʻia ka pipeline DN≤110 i ke kauwela, hoʻomoe iki i ka nahesa, DN≥110 pipeline ma muli o ke kūpaʻa ʻana o ka lepo, hiki ke pale i ke kaumaha wela, ʻaʻohe pono e mālama i ka lōʻihi o ka paipu;I ka hoʻoilo, ʻaʻohe pono e mālama i ka lōʻihi o ka paipu.
3, ka hoʻokomo ʻana o ka pipeline HDPE, inā liʻiliʻi ka wahi hana (e like me: pipeline well, ceiling construction, etc.), pono e hoʻohana i ka pilina fusion uila.
4. Ke hoʻohui ʻia ke kumu hoʻoheheʻe wela, ʻaʻole e kiʻekiʻe a lōʻihi paha ka wela wela, a e hoʻomalu ʻia ka mahana ma 210 ± 10 ℃, i ʻole e hoʻoheheʻe ʻia ka slurry hoʻoheheʻe ʻia i nā ʻāpana a hoʻemi i ka loko. anawaena o ka wai;Pono e maʻemaʻe ka paipu paipu a i ʻole ka hui paipu i ka wā e hoʻokomo ʻia ai ke kumu, i ʻole e haki ke kumu a kahe;I ka manawa like, pono e uku ʻia ka manaʻo e hoʻomalu i ka Angle a me ke kuhikuhi o nā paipu paipu e pale i ka hana hou.
5, hoʻoheheʻe wela ka pilina, pono ka volta ma waena o 200 ~ 220V, inā he kiʻekiʻe loa ka uila, e hoʻonui ka wela o ka pā wela, haʻahaʻa loa ka uila, a laila ʻaʻole hiki i ka mīkini butt ke hana maʻamau;Pono e hoʻopili ʻia ka ʻūhā i ka interface;inā ʻaʻole, ʻaʻole lawa ka ʻāpana kī, ʻaʻole lawa ka ikaika o ka hui kuʻi, a ʻaʻole pololei ka flange.Ke hoʻomaʻamaʻa ʻia ka pā wela, ʻaʻole i hoʻomaʻemaʻe ʻia ke kikowaena o ka paipu, a i ʻole nā mea haumia o ka pā wela e like me ka aila a me ka sediment, kahi e haki ai ka interface a leak.Pono e hoʻomalu maikaʻiʻia ka manawa hoʻomehana.ʻO ka manawa hoʻomehana pōkole a me ka lawa ʻole o ka manawa hoʻoheheʻe wela o ka paipu e liʻiliʻi loa ka hili ʻana.ʻO ka lōʻihi o ka manawa hoʻomehana ke kumu nui loa ka wili wili a hiki ke hana i ka wiliwili virtual.
