High-speed Energy-saving HDPE Pipe Extrusion Line

ʻO kā mākou hui noiʻi hou loa a me ka hoʻomohala ʻana i ka laina hana kiʻekiʻe e mālama i ka ikehu, kūpono no ka extrusion paipu polyolefin kiʻekiʻe. ʻO 35% ka mālama ʻana i ka ikehu a me ka hoʻonui ʻana o 1x i ka pono hana. Hoʻolālā kūikawā ʻia ʻo 38-40 L/D screw structure a me ka pahu pahu hānai e hoʻomaikaʻi maikaʻi loa i ka extrusion hehee a me nā hopena plasticizing. ʻO nā pahu pahu kiʻekiʻe-torque kiʻekiʻe e hōʻoia i ka hana paʻa o nā mea hana. Hoʻohana ʻia nā ʻāpana extrusion a me nā lima lima i ke ʻano hoʻolālā kiʻekiʻe loa. ʻO ka PLC variable frequency control vacuum tank, servo-driven multi-track tractor, a me ka wikiwiki-kiʻekiʻe chip-less cutter ua hoʻolako ʻia me kahi ʻōnaehana hoʻokele mika. ʻOi aku ka pololei o ka paona extrusion paipu.

ʻO ka paipu HDPE he paipu plastik maʻalahi i hana ʻia me ka thermoplastic high-density polyethylene i hoʻohana nui ʻia no ka wai haʻahaʻa haʻahaʻa a me ka hoʻoili kinoea. I kēia mau manawa i hala iho nei, ua hoʻohana nui ʻia nā paipu HDPE no ka lawe ʻana i ka wai inu, nā ʻōpala pōʻino, nā kinoea like ʻole, slurry, wai ahi, wai ʻino, a me nā mea ʻē aʻe. ʻO nā paipu polyethylene he mōʻaukala lawelawe lōʻihi a kaulana no ke kinoea, ʻaila, mining, wai, a me nā ʻoihana ʻē aʻe. Ma muli o kona haʻahaʻa haʻahaʻa a me ke kiʻekiʻe o ka corrosion, ke ulu nui nei ka ʻoihana paipu HDPE. I ka makahiki 1953, ua ʻike ʻo Karl Ziegler lāua ʻo Erhard Holzkamp i ka polyethene kiʻekiʻe kiʻekiʻe (HDPE). Hiki i nā paipu HDPE ke hana maika'i ma kahi ākea ākea o -2200 F a +1800 F. Akā na'e,'a'ole i mana'o 'ia ka ho'ohana 'ana i nā Paipu HDPE ke 'oi aku ka mahana o ka wai ma mua o 1220 F (500 C).

Hana ʻia nā paipu HDPE e ka polymerization o ka ethylene, kahi huahana o ka aila. Hoʻohui ʻia nā mea hoʻohui like ʻole (stabilizers, fillers, plasticizers, softeners, lubricants, colorants, flame retardants, blowing agents, crosslinking agents, ultraviolet degradable additives, etc.) i hoʻohui ʻia e hana i ka paipu HDPE hope a me nā ʻāpana. Hana ʻia nā lōʻihi paipu HDPE ma ka hoʻomehana ʻana i ka resin HDPE. A laila e hoʻokuʻu ʻia ma o kahi make, kahi e hoʻoholo ai i ke anawaena o ka pipeline. Hoʻoholo ʻia ka mānoanoa o ka pā paipu e ka hui pū ʻana o ka nui make, ka wikiwiki o ka wili, a me ka wikiwiki o ka tractor haul-off. ʻO ka maʻamau, hoʻohui ʻia ʻo 3-5% kalapona ʻeleʻele i HDPE e hana ia i ka pale UV, kahi e hoʻohuli ai i nā paipu HDPE i ʻeleʻele. Loaʻa nā ʻano kala ʻē aʻe akā ʻaʻole i hoʻohana pinepine ʻia. ʻO ka paipu HDPE waihoʻoluʻu a ʻeleʻele paha he 90-95% mau mea ʻeleʻele, kahi e hāʻawi ʻia ai kahi kaha kala ma 5% o waho.
