PE Conical Twin Screw Barrel

Hana ʻia kēia pahu pahu māhoe conical PE mai ke kila 38CrMoAla. He mea koʻikoʻi ka waiwai maka i ka hana ʻana, a koho mākou i ke kila ikaika a paʻa i ka ʻaʻahu mai nā mea hana kila Kina kaulana i kū i nā kūlana aupuni (GB/T 3077).

Hana ʻia nā pahu pahu māhoe conical PE o Nanhaiya mai nā kila kila kila kiʻekiʻe, e like me 38CrMoAlA, e hāʻawi ana i ka ʻaʻahu maikaʻi loa a me ka pale ʻana i ka corrosion a me ka ikaika wela kiʻekiʻe. ʻO ka Nitriding a me nā kaʻina hana ʻē aʻe e hoʻonui i ka paʻakikī o ka ʻili a me ke kūpaʻa ʻana, e hoʻonui i ke ola lawelawe. Hoʻoikaika ka hoʻolālā pahu pahu māhoe conical i nā ʻano kahe paʻa. Ma ka hōʻoia ʻana i ka ʻai meaʻai a me ke kaomi i loko o ke kaʻina extrusion, kōkua kēia i ka hōʻemi ʻana i nā anomalies kahe e like me ka fluctuations a i ʻole ka pulsations, e hōʻemi ana i ka ʻaʻahu o nā mea hana a me ka hoʻonui ʻana i ke ola lawelawe a me ka barela.

Na Nanhaiya's PE conical twin screw barrels ua loaʻa i nā R&D he nui a me ka hoʻomaikaʻi ʻana a ua hoʻohui ʻia i kēia manawa i loko o nā laina hana hana like ʻole, e loaʻa ana ka hana kiʻekiʻe. Hāʻawi mākou i kahi palapala hōʻoia 1-2 makahiki, e pili ana i ka ratio hoʻohui mea kikoʻī. Hana ʻia nā barela o Nanhaiya i kahi kaʻina hana nitriding, me kahi ʻāpana 2mm mānoanoa o ka nickel-tungsten alloy spray-welded ma nā wahi i hoʻopaʻa ʻia. Hoʻonui kēia i ka paʻakikī o ka pahu mai HRC55-60 a ʻoi aku ma luna o HRC65, e hoʻonui ana i ka pale ʻana i ka lole e 2-4 mau manawa.

ʻĀpana (Hōʻike)

Hiʻona a me ka noi

ʻO ka PE conical twin screw extruders e hōʻike pinepine ana i kahi hoʻolālā kūʻē i ka hoʻololi ʻana (e huli ana nā wili ʻelua ma nā ʻaoʻao ʻē aʻe). Hoʻokumu kēia i kahi ʻāpana liʻiliʻi liʻiliʻi, e hoʻohua ana i nā pūʻali koa ikaika (e paipai ana i ka plasticization PE) ʻoiai e ʻae ana i nā lele lele e hoʻomaʻemaʻe kekahi i kekahi (e hōʻemi ana i ke koena mea a pale i ka hōʻino ʻana).

ʻO Nanhaiya's PE conical twin screw extruders e hōʻike ana i kahi ʻae liʻiliʻi ma waena o nā mokulele wili a me ka pā barela (maʻamau 0.1-0.3mm). Hoʻohui pū ʻia me ka ʻoki a me nā hopena extrusion i hoʻokumu ʻia e nā wili hoʻololi kūʻē, hoʻoheheʻe koke lākou i nā granules PE a hoʻopuehu like i nā mea hoʻohui (e like me nā antioxidants a me nā kala). Hāʻawi ka hoʻolālā screw i wahi no nā puka makani a me nā kānana hoʻoheheʻe, e ʻae iā lākou e hana me ka ʻōnaehana exhaust o ka barela e hoʻoneʻe i ka makū a me nā mea haʻahaʻa haʻahaʻa-molecular-weight mai ka hoʻoheheʻe ʻana o ka PE, e hōʻoiaʻiʻo ana i kahi huahana manuahi ʻole. Hiki ke hoʻohana ʻia nā kānana o nā nui pore e kānana i nā haumia a hoʻonui i ka maʻemaʻe o ka huahana.

Ua kūpono ka PE conical twin screw barrel me nā ʻano mea like ʻole PE: LDPE (polyethylene haʻahaʻa haʻahaʻa), HDPE (polyethylene kiʻekiʻe kiʻekiʻe), LLDPE (polyethylene low-density linear), a me nā ʻano PE ʻē aʻe. Ma ka hoʻoponopono ʻana i ka wikiwiki o ka wili a me nā ʻāpana groove, hiki iā ia ke hoʻokipa i nā mea maka PE me nā ʻōlelo kuhikuhi hehee like ʻole. Hiki ke hoʻohana ʻia no ka extrusion o nā paipu PE, profiles, a me nā kiʻiʻoniʻoni, a me ka pelletization PE a me ka hoʻololi ʻana (e like me ke aniani fiber reinforcement a me ka hoʻololi ʻana i ka lapalapa ahi). He kūpono loa ia no ka hana ʻana i nā pahu liʻiliʻi a me nā ʻano huahana PE.

Nā kikoʻī huahana

ʻO ka hoʻomaʻamaʻa kiʻekiʻe, ka mīkini pololei, a me nā kaʻina hana nitriding e hōʻoia i ka hana piha o nā mea nui.

Hoʻoikaika ʻia nā wahi palupalu o ka screw a me ka barela me kahi ʻāpana nickel-tungsten alloy, e loaʻa ana i kahi papa mānoanoa 2-3mm a hoʻomaikaʻi nui i ka pale ʻana i ka lole.
