ʻO ka māhoe māhoe conical non-intermeshing

Hana ʻia kēia māhoe conical non-intermeshing 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).

ʻO Nanhaiya's non-intermeshing conical twin-screw extruders i non-interlocking flights. ʻO nā ʻokoʻa ma waena o nā wili a ma waena o ka wili a me ka pā barela he nui (maʻamau 0.5-2mm), a hiki ke hoʻoponopono ʻia kēia mau ʻokoʻa ma muli o nā hiʻohiʻona mea e pale aku ai i ka extrusion a me ka shearing e pili ana me nā wili intermeshing. Hoʻopili ʻia nā wili, me ka emi ʻana o nā anawaena mai ka hopena hānai a i ka hopena hoʻokuʻu. Kaʻa kaʻawale nā ​​ʻūlū ʻelua (me nā wikiwiki hiki ke hoʻololi ʻia). Hāʻawi mua ʻia nā mea ma ka friction a me ke axial thrust mai nā ʻōwili wili, ma mua o ka hana "paʻi" o nā mokulele intermeshing. Ke hilinaʻi nui nei i ke kahe kūlohelohe o ka mea i loko o ke kaila wili a me kahi liʻiliʻi o ka hui ʻana o ka convection, ʻaʻole maikaʻi ka dispersion uniformity o nā mea hoʻohui (e like me nā masterbatches a me nā mea hoʻopiha), no laila ʻaʻole kūpono ia no nā huahana e koi ana i ka hoʻohuihui kiʻekiʻe (e like me nā kiʻiʻoniʻoni a me nā kikoʻī kikoʻī).

Ua loaʻa iā Nanhaiya ka non-intermeshing conical twin screw barela he nui i ka R&D a me ka hoʻomaikaʻi ʻana a i kēia manawa 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 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.

Hiʻona a me ka noi

Non-intermeshing conical twin-screw extruders, ma muli o ka nele o ka intermeshing lele shear, ike loa emi mechanical shear ikaika i loko o ka wili ma mua intermeshing twin-screw extruders. Mālama maikaʻi kēia i ka hoʻohaʻahaʻa ʻana a i ʻole ka haki ʻana o ka fiber o nā mea shear-sensitive (e like me nā mea hoʻoheheʻe haʻahaʻa a me nā mea i hoʻoikaika ʻia i ka fiber).

Hoʻohana mua ʻia lākou e hana i nā huahana maʻamau me ka ʻole o nā mea hoʻohui paʻakikī, e like me nā paipu wai PVC maʻamau, kiʻi ʻoniʻoni ʻo PE, a me nā koʻokoʻo plastic maʻalahi, kahi e pono ʻole ai ka hui ʻana kiʻekiʻe e hoʻokō i nā koi maikaʻi. Hāʻawi ko lākou mau ʻauwaʻa hohonu hohonu a me ka hiki ke lawe kiʻekiʻe i kahi kahe hoʻoheheʻe paʻa kiʻekiʻe, e kūpono ana ia no nā noi e koi ana i ka hoʻopuka kiʻekiʻe akā ʻoi aku ka liʻiliʻi o ka hoʻohui ʻana i ka pololei, e like me nā paipu PVC nui-diameter (e laʻa, DN300 a i luna) a me nā pepa plastik mānoanoa.
