A conical twin screw extruderHe ʻano o ka māhoe hoʻoheheʻe wiliwili ʻelua i hoʻonohonoho ʻia ma ke ʻano conical, e hoʻopaʻa ʻia i ka hopena hoʻokuʻu o ka extruder.Hāʻawi kēia hoʻolālā i ka hoʻohaʻahaʻa mālie ʻana i ka nui o ke kahawai screw, e hopena i ka hoʻonui ʻana i ke kaomi a me ka hoʻohui ʻia ʻana.ʻO ka conical twin screw extruder ka mea nui o ka barrel screw, gear transmission system, quantitative feeding, vacuum exhaust, heat, cooling and electrical control parts.
ʻO kahi conical twin screw extruder kūpono no ka hana ʻana i nā huahana PVC mai ka pauka hui ʻia.ʻO PVC kahi polymer thermoplastic i loaʻa i ka nui o nā noi i nā ʻoihana like ʻole, e like me ke kūkulu ʻana, ka pahu, ka uila, ka automotive, a me ka lāʻau lapaʻau.Eia naʻe, ʻaʻole kūpono ʻo PVC me nā polymers ʻē aʻe a me nā mea hoʻohui, a koi i nā ʻenehana hana kūikawā e hoʻokō i nā waiwai i makemake ʻia a me ka hana.Hiki i kahi conical twin screw extruder ke hāʻawi i ka hui ʻana, hoʻoheheʻe, devolatilization, a me ka homogenization o PVC a me kāna mau mea hoʻohui i kahi ʻano hoʻomau a maikaʻi.
ʻO kahi extruder māhoe māhoe conical kekahi mea hana kūikawā no ka extrusion pauka WPC.Kū ʻo WPC no ka lāʻau-plastic composite, ʻo ia ka mea e hui pū ai i nā lāʻau a i ʻole ka palaoa lāʻau me nā polymers thermoplastic, e like me PVC, PE, PP, a i ʻole PLA.Loaʻa iā WPC nā mea maikaʻi o ka lāʻau a me ka plastic, e like me ka ikaika kiʻekiʻe, ka lōʻihi, ka pale ʻana i ka wā, a me ka recyclability.Hiki i ka conical twin screw extruder ke hana i ka pauka WPC me ka puka kiʻekiʻe, ka holo paʻa, a me ke ola lawelawe lōʻihi.
Me nā ʻano like ʻole a me nā mea hana i lalo, hiki i ka conical twin screw extruder ke hana i nā huahana PVC a me WPC like ʻole, e like me nā paipu, nā kaupaku, nā kiʻi pukaaniani, ka pepa, ka decking, a me nā granules.Loaʻa i kēia mau huahana nā ʻano like ʻole, ka nui, a me nā hana, a hiki ke hoʻokō i nā pono like ʻole o nā mea kūʻai aku a me nā mākeke.
Ka wehewehena kaʻina hana
Hiki ke hoʻokaʻawale ʻia ke kaʻina hana o ka conical twin screw extrusion i ʻehā mau ʻanuʻu nui: hānai, hoʻoheheʻe, devolatilization, a hoʻohua.
Hanai
ʻO ka hana mua o ka extrusion twin screw conical ʻo ka hānai ʻana.I kēia kaʻina, ʻo nā mea maka, e like me ka PVC a i ʻole WPC pauka, a me nā mea hoʻohui ʻē aʻe, e like me nā stabilizers, lubricants, fillers, pigments, a me nā mea hoʻololi, ua hoʻopaʻa ʻia a hānai ʻia i loko o ka extruder e nā mea hānai ʻokoʻa, e like me nā screw augers, vibratory. nā pā, nā kāʻei paona, a me nā ʻumeke.ʻO ka helu hānai a me ka pololei nā mea nui e pili ana i ka maikaʻi a me ke kūlike o nā huahana hope.Hiki ke hoʻohui mua ʻia nā mea maka a hānai ʻia, a i ʻole kaʻawale a me ka sequentially metered i loko o ka extruder, ma muli o ka hoʻokumu ʻana a me nā waiwai i makemake ʻia o nā huahana.
Heheʻe
He hehee ka papa lua o ka extrusion twin screw conical.I kēia kaʻina, lawe ʻia nā mea maka, hoʻopaʻa ʻia, a hoʻomehana ʻia e nā wili wili a me nā mea hoʻomehana barela, a hoʻololi ʻia mai ka paʻa i ka wai.ʻO ke kaʻina hoʻoheheʻe e pili ana i ka hoʻokomo ʻana i ka ikehu wela a me ka mechanical, a ua hoʻohuli ʻia e ka wikiwiki o ka screw, ka hoʻonohonoho ʻana, ka wela o ka pahu, a me nā waiwai waiwai.He mea koʻikoʻi ke kaʻina hoʻoheheʻe no ka hoʻopuehu ʻana a me ka hāʻawi ʻana i nā mea hoʻohui i loko o ka polimer matrix, a me ka hoʻomaka ʻana o nā hopena kemika, e like me ka hoʻopili ʻana, grafting, a i ʻole degradation, e hiki mai ana i ka heheʻe.Pono e hoʻomalu pono ʻia ke kaʻina hoʻoheheʻe ʻana e pale aku i ka wela, ka ʻohi nui ʻana, a i ʻole ka hoʻoheheʻe ʻia ʻana o nā mea waiwai, i hiki ke hopena i ka maikaʻi o ka huahana a me ka hana.
Devolatilization
ʻO ke kolu o ka pae o ka conical twin screw extrusion he devolatilization.I kēia pae, ua hoʻoneʻe ʻia nā mea hoʻoheheʻe, e like me ka moisture, ea, monomers, solvents, a me nā huahana decomposition, mai ka hoʻoheheʻe ʻana ma o ka hoʻohana ʻana i ka vacuum ma nā puka makani ma ka pahu extruder.Pono ke kaʻina hana devolatilization no ka hoʻomaikaʻi ʻana i ka maikaʻi o ka huahana a me ke kūpaʻa, a me ka hōʻemi ʻana i ka hopena o ke kaiapuni a me nā pōʻino olakino o ke kaʻina extrusion.ʻO ke kaʻina hana devolatilization e pili ana i ka hoʻolālā screw, pae vacuum, melt viscosity, a me nā ʻano waiwai.Pono e hoʻoikaika ʻia ke kaʻina hana devolatilization e hoʻokō pono i ka wehe ʻana i nā volatiles me ka ʻole o ka hoʻoulu ʻana i ka huʻa, ka wai kahe, a i ʻole ka hoʻoheheʻe ʻana.
Hoʻohalahala
ʻO ka ʻehā a me ka pae hope o ka extrusion māhoe conical māhoe e hana ana.I kēia pae, hoʻoheheʻe ʻia ka heheʻe ma o ka make a i ʻole ka ʻōpala e hoʻoholo ai i ke ʻano a me ka nui o ka huahana.Hiki ke hoʻolālā ʻia ka die a i ʻole mold e hana i nā huahana like ʻole, e like me nā paipu, profiles, sheet, film, a i ʻole granules.Hoʻopili ʻia ke kaʻina hana e ka geometry die, ke kaomi make, ka mahana make, a me ka rheology hehee.Pono e hoʻoponopono ʻia ke kaʻina hana no ka loaʻa ʻana o nā extrudates like ʻole me ka ʻole o nā hemahema, e like me ka pehu make, ka haʻihaʻi hoʻoheheʻe, a i ʻole ke ʻano instability.Ma hope o ke kaʻina hana, hoʻomaʻalili ʻia nā extrudates, ʻoki ʻia, a hōʻiliʻili ʻia e nā mea hana o lalo, e like me nā calibrators, haul-offs, cutters, a me winders.
Ka hopena
ʻO kahi conical twin screw extruder he mea maʻalahi a kūpono hoʻi no ka hana ʻana i nā huahana PVC a me WPC mai ka pauka hui ʻia.Hiki iā ia ke hāʻawi i nā hana pono o ka hānai ʻana, ka hoʻoheheʻe ʻana, ka devolatilization, a me ka hoʻohua ʻana i ke ʻano hoʻomau a hoʻomalu ʻia.Hiki iā ia ke hana i nā huahana like ʻole me nā ʻano like ʻole, ka nui, a me nā hana, me ka hoʻohana ʻana i nā ʻano like ʻole a me nā mea hana i lalo.Loaʻa i kahi extruder māhoe conical māhoe o ka hui ʻana maikaʻi, ka hoʻopuka nui, ka holo paʻa, a me ke ola lawelawe lōʻihi, a hiki ke hoʻokō i nā pono like ʻole o nā mea kūʻai aku a me nā mākeke.
No ka ʻike hou aku a i ʻole nā nīnau, e ʻoluʻolukāhea iā mā˚ou:
