ʻO kēia ke kaʻina hana o kahi ʻoihana hana pahu meaʻai, hiki iā ʻoe ke kuhikuhi e aʻo i ka ʻike pili orohoʻopaʻa ʻana.
Rotomolding he hana hou a holomua o ka hoʻoili ʻana i ka plastic, i hōʻike ʻia e:
1, kūpono no ka hana ʻananā huahana hollow nui, e like mepahu wai, pahu ʻaila, mea lealea nui, pā kaʻawale, etc.
2,He haʻahaʻa ke kumukūʻai hana, ʻoi aku ka nui o ke kumukūʻai mold he 1/3 wale nō o ka injection mold.ʻO kona hemahema, ʻo ia ke koi kiʻekiʻe no nā mea maka, a ʻoi aku ka maikaʻi o ka hoʻoponopono ʻana i ka huahana i hoʻohālikelike ʻia me ka hoʻoheheʻe injection.
ʻO kāna hana hana penei:
一、Ka hoʻomākaukau ʻana i nā mea maka
(一) Pono mea maka nolokomolding hana ʻana
ʻAʻole ma mua o 5.0g / 10min ka 1.melting index.
2.powder particles 30 ~ 60 mesh (poe poepoe hiki ole i ka nui o ka huelo a me ka prisms, flake particles).
3. maloʻo.
(二) Nā koi no nā mea makaka hana ʻana i nā plastics rolling
He paʻakikī ka LLDPE hoʻokahi kaula kaula e hōʻoia i nā koi kikoʻī o nā huahana (e like me nā pahu mālama kaua i hana ʻia e kā mākou hui), no laila, hoʻohana maʻamau nā mea composite (ʻike ʻia ʻo ka plastic modification), e like me nā mea 7042 a me UR644 me ka wai maikaʻi. aka, lawa ole ka ikaika.No laila i mea e hōʻoia ai i ka maikaʻi o nā huahana kikoʻī, 7042, 6090, 500S a i ʻole UR644, A760.Loaʻa ka ʻano kumu waiwai waiwai ma hope o nā ʻumi miliona o nā hoʻokolohua ʻepekema, hūnā ʻia, patent, ʻaʻole hiki i kekahi ke hoʻololi i ke ʻano me ka ʻole o ka hoʻāʻo ʻana.
Pono e hoʻohui ʻia kahi huahana kikoʻī e like me ka hana ʻana o ka huahana, kekahi haku, antioxidants, e like me ka hana ʻana o ke kala e hui pū me ka haku ʻōpala ʻōwili.Hoʻohana ʻia ka huahana ma waho no ka manawa lōʻihi, e hoʻohui ana i nā antioxidants, ka hana ʻana i nā mea pale ahi, nā anti-aging agents, promoters a pēlā aku.
(三) ke kaʻina hana ʻenehana kikoʻī
1. E like me ka hoʻonohonoho ʻana o ke alakaʻi, hoʻokomo ʻia nā ʻano mea maka a me nā accelerators i helu ʻia ma ke ʻano huahana i loko o ka mixer e nā limahana i hāʻawi ʻia, a ua hui pū ʻia ka mixer i ka hoʻomaka ʻana o ka hui.ʻO ka manawa hui ʻana he> 10 mau minuke (ua māhele ʻia ka mea hui i ka mixer maʻamau a me ka mixer kiʻekiʻe, a ua ʻōlelo ʻia e hoʻohana i ka mixer kiʻekiʻe inā ʻae ka waihona. nā mea maka, pono e hoʻohana me nā mea hana maʻamau kūpono.
2, extrusion granulation mīkini mea hoʻohana me ka lima disk kaʻa pulley, hiki i ka mīkini ke holo maʻalahi, ka mea ma hope o ka hui ʻana i loko o ka mīkini granulation, pihi kaʻa a pēlā aku.Ma hope o ka piʻi ʻana o ka ammeter kaʻa, e pani i ke pihi hoʻomehana a hoʻoponopono i ka mahana o ka wahi mehana.Ua kūʻai aku kaʻu hui i ka mīkini granulating i ʻehā mau wahi hoʻomehana, mai ka hopper i mua i ka huli: kēlā me kēia wahi, maʻamau 150 ℃.ʻO ka lua o ka ʻāpana he 180 ℃.Ma hope o ka pau ʻana o ke kolu o ka ʻāpana 180 ℃.He 190 ℃ ka ihu.
Ma hope o ka hoʻomaʻamaʻa ʻana o ka mea extruded e ka pahu wai, hoʻokomo ʻia i loko o ka granulator a pani ʻia ka mana o ka granulator.E huki ʻakomi ka mīkini pelleting i loko o ka ʻāpana mea no ka pelleting.Pono ka mea hana mīkini e nānā i ka hana o ka extruder, inā e ʻike ʻia e ʻoki i waho o ka puka extruder, pono e ʻoki koke i ke kumu uila a noho ma hope o ka pau ʻana o ka hana ʻana o ka mīkini mai ka make extruder ihu, e hoʻololi i ka mesh hou. (Mesh kahiko me ka ʻole o ka pōʻino ma hope o ke ahi, hiki nō ke hoʻomau i ka hoʻohana ʻana), wehe hou ʻia ka extrusion granulator, nā mea ʻilika maka i ka hui ma ke ʻano he mea hou.Ma hope o ka extrusion, pono e hoʻomaloʻo pono ʻia ka mea e like me ke kūlana maoli o ka mea ma mua o ka granulation.
ʻO ke kumu o kēia kaʻina hana e hoʻololi i nā mea maka.Nānā: Pono e hoʻoponopono ʻia ka mahana wela o nā mea maka e like me nā ʻano mea maka.
ʻO ka extruder granulator he pālua ʻelua a me nā helu hoʻokahi, ʻoki anuanu a me nā wahi wela, ke hoʻohana nei ka hui i ka granulator ʻoki anuanu.
3. ʻO ka wili ʻana i ka pauka he mea pono ia ma mua o ka ʻōwili ʻana i ka hana no ka mea ʻo ka mea i hoʻohana ʻia i ka hana ʻōwili ʻana he mea pauka, a ʻo ka mea maka i kūʻai ʻia e ka mākeke he mea granule.Ma hope o ka nānā ʻana o ka mea hana granulator ʻaʻohe mea ʻē i loko o ka mīkini, hoʻokomo ʻia ka mea granular ma hope o ka granulation i loko o ka hopper, hoʻomaka ka mīkini wili, a hoʻoponopono ʻia ka wikiwiki hānai no ka wili.Ma hope o ka wili ʻana, e hoʻomaloʻo ʻia nā mea maka e like me ke kūpono, a ʻaʻole ʻoi aku ka mahana o ka maloʻo ma mua o 30 ℃.
Ke nānā nei kēia kaʻina hana i ka maikaʻi o ka pauka wili, ka nui o ka 30 ~ 60 mesh, nā ʻāpana pōʻai, ʻaʻohe kihi, nā kihi, flake, trailing particles.
