Hoʻokahi Screw ʻAno Māmā

Hana ʻia kēia ʻano wili hoʻokahi 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).

Māhele ʻia nā mea hoʻoheheʻe hoʻokahi o Nanhaiya tgradual-type i ʻekolu mau ʻāpana e pili ana i kā lākou hana. ʻO ka hohonu o nā ʻohe i kēlā me kēia ʻāpana e emi iho ana me ka ʻike ʻole ʻia o nā loli koke, e hana ana i kahi ʻano maʻalahi, "gradual".

He 20%-30% ka nui o ka lō'ihi o ka pauku hānai. ʻO ka ʻāpana koʻikoʻi, ʻo ka ʻāpana waena o ka wili, ʻo ia ka hapa nui loa (40% -50%) a ʻo ia ke kumu o ka hana lohi. Hoʻomaka ka hohonu o ka ʻohe i kona kiʻekiʻe loa ma ka ʻāpana hānai a me ka liʻiliʻi a me ka emi ʻana ma ka lōʻihi o ka wili, e hana ana i kahi "ʻāpana hoʻokūkū."

Hoʻohui hou ka ʻāpana homogenization a hoʻonāukiuki i ka heheʻe, e hōʻoia i ka wela hoʻoheheʻe a me ka viscosity. Hāʻawi ʻia ka mea i ke poʻo make ma ke kaomi paʻa a me ke kahe kahe, e hōʻoia ana i ka maikaʻi o ka huahana extruded.

Ua loaʻa i nā ʻano R&D he nui a me nā hoʻomaikaʻi hou ʻana o Nanhaiya a ua hoʻohui ʻia i loko o nā laina hana o nā mea 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 papa mānoanoa 0.8 ~ 2m o ka nickel-tungsten alloy spray-welded ma nā wahi i hoʻopaʻa ʻia. Hoʻonui kēia i ka paʻakikī o ka pahu ʻo HRC55 ~ 62, e hoʻonui ana i ka pale ʻana i ka lole e 2-3 mau manawa.

ʻĀpana ʻenehana

Hiʻona a me ka noi

ʻO Nanhaiya's gradual-type single screw extruder e hōʻike ana i kahi ʻano hana ʻekolu me nā māhele hana i wehewehe pono ʻia. Hiki ke hoʻololi pono ʻia nā ʻāpana kaʻina hana (ka wela, ka wikiwiki, a me ke kaomi hope) me ka maʻalahi o ka hana ma mua o nā wili kūikawā.

Ka Hoʻomalu Maʻalahi: ʻO ka hoʻonohonoho ʻana o ka mahana ʻekolu ma muli o ke kumu "gradient increase". ʻO ka ʻāpana hānai ka haʻahaʻa haʻahaʻa loa (pono wale nō e hoʻomaʻamaʻa i ka mea, e like me 50-80 ° C no ka hoʻoili ʻana i ka PE), hoʻonui mālie ka ʻāpana compression i ka mahana (e hiki i ka helu hoʻoheheʻe, e like me 160-180 ° C no PE), a hoʻopaʻa ʻia ka ʻāpana homogenization i ka helu heheʻe (e like me 180-200 ° C no PE). ʻAʻole koi ʻia nā hoʻololi wela kūloko paʻakikī.

Linear Correlation ma waena o ka Speed ​​a me Output: I loko o ka wikiwiki kūpono (maʻamau 30-150 rpm), piʻi ka hoʻopuka ma kahi laina laina me ka wikiwiki o ka screw, e hoʻopau ana i ka pono no ka hoʻololi pinepine ʻana i ka backpressure. ʻO kēia ka mea kūpono i nā mea hoʻohana hou a hoʻomaʻamaʻa i ka hoʻomau a paʻa i ka hana nui (e like me 24-hola hoʻomau mau o nā paipu a me nā kiʻiʻoniʻoni).

Ke koi haʻahaʻa haʻahaʻa puʻe: ʻO ka hohonu o ka wili i loko o ka ʻāpana homogenization mau a pāpaʻu, a ʻo kahi kaomi maʻamau o 3-8 bar e koi ʻia e hōʻoia i ka hoʻoheheʻe ʻana. ʻO ka nui o ke kaomi hope e hoʻonui i ka torque screw, hoʻonui i ka hoʻohana ʻana i ka ikehu, a me ka hoʻoheheʻe ʻana i ka wela, a kiʻekiʻe ke kaʻina hana "hoʻomanawanui".

ʻO ka mea hoʻoheheʻe wili hoʻokahi ʻano haʻahaʻa kūpono no ka hana ʻana i nā kiʻiʻoniʻoni PE (polyethylene) (e like me ka uhi ʻai meaʻai, nā ʻeke kūʻai hale kūʻai nui, a me nā ʻeke hoʻopuka hōʻike wai wai), PP (polypropylene) strapping tape, a me PVC (polyvinyl chloride) wela wela. Hiki iā ia ke hana i nā paipu wai PVC, nā paipu wai PPR, nā paipu kinoea PE, a me nā kiʻi kiʻi puka aniani. Hiki iā ia ke hana i nā kīʻaha plastik PE, nā bākeke plastik PP, ka pahu uwea PVC, a me nā pahu waiho ʻilika. Hiki iā ia ke pelletize PE a me PP i nā mea hana hou a hana i nā paipu PE i hoʻopiha ʻia me ka 10% calcium carbonate.

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 ka nickel-tungsten alloy layer, e loaʻa ana i kahi papa mānoanoa 0.8-2.0mm a hoʻomaikaʻi nui i ka pale ʻana i ka lole.
