Hiki ke hana a hana ʻia ka PE ma nā ʻano like ʻole.Ke hoʻohana nei i ka ethylene ma ke ʻano he kumu nui, propylene, 1-butene a me hexene ma ke ʻano he copolymers, ma lalo o ka hana a nā catalysts, me ka hoʻohana ʻana i ka slurry polymerization a i ʻole ke kaʻina polymerization kinoea, ka polymer i loaʻa ma ka flash evaporation, kaʻawale, ka maloʻo a me ka granulation e loaʻa ai nā ʻāpana like o ka huahana pau.Hoʻopili kēia i nā kaʻina e like me ka extrusion sheet, extrusion film, pipe or profile extrusion, blow molding, injection molding, a me ka roll molding.
Extrusion: ʻO ka papa i hoʻohana ʻia no ka hana extrusion ma ke ʻano he melt index ma lalo o 1, ʻo MWD ka laulā waena.Loaʻa ka MI haʻahaʻa i ka wā e hana ai i ka ikaika hoʻoheheʻe kūpono.ʻOi aku ka maikaʻi o nā māka MWD ākea no nā extrusions no ka mea ʻoi aku ka kiʻekiʻe o ka hana ʻana, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa wehe ʻana, a me ka haʻahaʻa haʻahaʻa haʻahaʻa.
Loaʻa i ka PE nā noi extrusion he nui e like me nā uea, nā kaula, nā hoses, nā paipu a me nā profiles.Hoʻopili ʻia nā noi paipu mai nā paipu melemele liʻiliʻi no ke kinoea maoli a i nā paipu ʻeleʻele ʻeleʻele mānoanoa 48 iniha ke anawaena no nā paipu ʻoihana a me ke aupuni.Ke ulu wikiwiki nei nā paipu pā ākea nui ma ke ʻano he mau mea ʻē aʻe i nā ʻauwai ʻino a me nā mea ʻaʻa ʻē aʻe.
1.Sheet a me Thermoforming: ʻO ka uhi ʻana o ka thermoforming o nā mea hoʻoluʻu ʻano picnic nui i hana ʻia me PE no ka paʻakikī, ke kaumaha māmā a me ka lōʻihi.ʻO nā ʻāpana ʻē aʻe a me nā huahana thermoforming e pili ana i nā fenders, nā lining tank, nā papa a me nā kiaʻi kīʻaha, nā pahu hoʻouna a me nā pahu.Ma muli o ka paʻakikī o ka MDPE, kūpaʻa i ka corrosion kemika a me ka impermeable, ʻo ka nui a me ka wikiwiki o ka nui o nā palapala noi he mulch a i ʻole ka wai lalo ʻo Muri.
2.Blow molding: ʻOi aku ma mua o hoʻokahi hapakolu o HDPE i kūʻai ʻia ma ʻAmelika Hui Pū ʻIa no nā noi hoʻoheheʻe ʻana.ʻO kēia mau mea mai nā omole i loaʻa ka bleach, ka aila kaʻa, ka mea hoʻomaʻemaʻe, ka waiū a me ka wai hoʻoheheʻe ʻia i nā pahu hau nui, nā pahu wahie kaʻa a me nā pahu inika.Loaʻa i nā māka hoʻoheheʻe ʻana i nā kikoʻī hana e like me ka ikaika heheʻe, ES-CR a me ka paʻakikī e like me nā mea i hoʻohana ʻia no ka palapala a me nā noi thermoforming, no laila hiki ke hoʻohana ʻia nā māka like.
Hoʻohana mau ʻia ka hoʻoheheʻe ʻia ʻana no ka hana ʻana i nā ipu liʻiliʻi (emi ma lalo o 16 auneke) no ka hoʻopili ʻana i nā lāʻau lapaʻau, shampoos, a me nā mea hoʻonaninani.ʻO kahi pōmaikaʻi o kēia kaʻina hana ʻo ia ka hana ʻana o nā ʻōmole e ka wehe ʻana i ka bottleneck maʻalahi, e hoʻopau ana i ka pono o nā ʻanuʻu ma hope o ka hoʻopau ʻana i pili maʻamau me nā kaʻina hana puhi.ʻOiai hoʻohana ʻia kekahi mau māka MWD haiki no ka hoʻomaikaʻi ʻana i ka hoʻopau ʻana i ka ʻili, hoʻohana mau ʻia nā māka MWD waena a ākea.
3. Injection molding: He nui nā noi ʻana o HDPE, mai nā kīʻaha inu ʻeleʻele hiki ke hoʻohana hou ʻia i nā kini 5-gsl e hoʻopau i ka hapalima o ka HDPE i hana ʻia ma ka home.Loaʻa i nā māka injection kahi helu hehee o 5 a 10 a hāʻawi i nā māka kahe haʻahaʻa no ka paʻakikī a me nā māka kahe kiʻekiʻe no ka machinability.Hoʻohana ʻia nā mea e pono ai i kēlā me kēia lā a me ka ʻai ʻana i ka pā aniani;ʻO nā kini meaʻai paʻakikī a me nā kini pena;Ke kū'ē kiʻekiʻe i nā noi hoʻoheheʻe kaiapuni e like me nā pahu wahie mīkini liʻiliʻi a me nā kini ʻōpala 90 galani.
4.Rolling: ʻO nā mea e hoʻohana ana i kēia kaʻina hana maʻamau e ʻoki ʻia i loko o nā mea pauka hiki ke hoʻoheheʻe a kahe i ka pōʻai wela.Hoʻohana ʻia nā ʻano ʻelua o ka PE no ka ʻōwili ʻana: ke kumu nui a me ka hoʻopili kea.Loaʻa i ka MDPE/HDPE ka mānoanoa maʻamau i ka 0.935 a i ka 0.945 g/CC me kahi MWD haiki, e loaʻa ana i kahi huahana hopena kiʻekiʻe me ka liʻiliʻi liʻiliʻi a me ka helu helu hehee o 3-8.ʻAʻole kūpono nā māka MI kiʻekiʻe no ka mea ʻaʻole i loaʻa iā lākou ke kūʻē i ka hopena a me ke kūpaʻa ʻana i ke koʻikoʻi kaiapuni e pono ai no nā huahana i hoʻoheheʻe ʻia.
Hoʻohana pono nā noi ʻōwili hana kiʻekiʻe i kāna mau waiwai kūʻokoʻa o nā māka i hoʻohui ʻia me ke kemika.Holo maikaʻi kēia mau māka i ka ʻāpana mua o ka pōʻaiapuni molding a laila hoʻopili ʻia e hoʻomohala i ko lākou ʻoi aku ka maikaʻi o ke koʻikoʻi kaiapuni.ʻAʻahu a kūʻē i ka wā.He kūpono loa ka polyethylene crosslinked no nā ipu nui, mai 500 galani pahu i hoʻohana ʻia no ka lawe ʻana i nā ʻano kemika a hiki i 20,000 galani pahu mālama mahiʻai.
5.Kiʻiʻoniʻoni: Hoʻohana maʻamau ka hana kiʻiʻoniʻoni PE i ka hana kiʻiʻoniʻoni maʻamau a i ʻole ke ʻano hana extrusion pālahalaha.ʻO ka hapa nui o ka PE no nā kiʻiʻoniʻoni lahilahi a hiki ke hoʻohana ʻia me Universal Low density PE (LDPE) a i ʻole linear Low Density PE (LLDPE).Hoʻohana mau ʻia nā māka kiʻiʻoniʻoni HDPE kahi e pono ai nā waiwai tensile maikaʻi a me ka impermeability maikaʻi loa.No ka laʻana, hoʻohana mau ʻia nā kiʻiʻoniʻoni HDPE i nā ʻeke kūʻai, ʻeke meaʻai a me nā ʻeke meaʻai.
