ʻO nā uea, nā kaulahao, nā hose, nā paipu, a me nā ʻaoʻao he mau noi wale nō no ka PE. Loaʻa nā noi no nā paipu mai nā paipu ʻeleʻele me ka paia mānoanoa he 48-ʻīniha no nā paipu ʻoihana a me ke kūlanakauhale a hiki i nā paipu melemele liʻiliʻi no ke kinoea kūlohelohe. Ke hoʻonui koke nei ka hoʻohana ʻana i ka paipu paia hakahaka nui ma kahi o nā laina ʻauwai a me nā ʻauwai ʻino i hana ʻia me ka sima.
ʻO ka hoʻokumu ʻana i ka thermoform a me nā pepa
He nui nā mea hoʻoluʻu pikiniki nui e hoʻokomo i nā liners thermoformed i haku ʻia me PE, ka mea e hāʻawi ai i ka lōʻihi, ka māmā, a me ka paʻakikī. ʻO nā pale, nā liners tank, nā pale pan, nā pahu ukana, a me nā tanks he mau laʻana o nā pepa hou a me nā mea thermoformed. ʻO ka Mulch a i ʻole nā ​​​​lalo o ka loko, e hilinaʻi ana i ka paʻakikī o MDPE, ke kūpaʻa kemika, a me ka impermeability, ʻelua mau noi pepa koʻikoʻi a wikiwiki hoʻi.
Nā ʻōmole puhi
Ua kūʻai aku ʻo ʻAmelika Hui Pū ʻIa ma mua o hoʻokahi hapakolu o kānaHDPEno ka hoʻoheheʻe ʻana i ka puhi. Loaʻa lākou mai nā pahu hau liʻiliʻi, nā pahu hau nui, nā pahu wahie kaʻa, a me nā pahu wai a hiki i nā ʻōmole bleach, ka ʻaila kaʻa, ka detergent, ka waiū, a me ka wai mālie. Hiki ke hoʻohana ʻia nā ʻano like no nā noi pepa a me ka thermoforming ʻoiai ʻo ka ikaika hoʻoheheʻe, ES-CR, a me ka paʻakikī he mau māka ʻokoʻa o nā ʻano hoʻoheheʻe puhi.
hoʻokomo
Hana pinepine ʻia nā ipu liʻiliʻi (ʻaʻole iʻoi aku ma mua o 16oz) me ka hoʻohana ʻana i ka hoʻoheheʻe ʻana i ka ʻōpala no ka hoʻopili ʻana i nā shampoos, nā mea hoʻonani, a me nā lāʻau lapaʻau i kuhikuhi ʻia. ʻO kahi pōmaikaʻi o kēia ʻano hana, ʻo ia ka ʻoki ʻia ʻana o nā ʻōmole i hoʻopau ʻia, ʻaʻole like me nā kaʻina hana hoʻoheheʻe ʻana maʻamau e pono ai nā hana ma hope o ka hoʻopau ʻana. ʻOiai ua hoʻohana ʻia kekahi mau māka MWD haiki e hoʻomaikaʻi i ka polish ʻili, hoʻohana pinepine ʻia nā māka MWD waena a ākea.
hoʻoheheʻe ʻana i ka pahu
ʻO ka hapakolu o ka mea i hana ʻia ma ka ʻāinaHDPEHoʻohana ʻia i nā noi e kū ana mai nā kini 5-gsl a hiki i nā kīʻaha inu paia lahilahi hiki ke hoʻohana hou ʻia. Aia nā pae wai haʻahaʻa me ka paʻakikī a me nā pae wai kiʻekiʻe me ka machinability, a ʻo nā papa hoʻoheheʻe injection maʻamau he helu hoʻoheheʻe o 5 a 10. ʻO nā waiwai paia lahilahi a me nā ʻōpala meaʻai, nā kini meaʻai paʻakikī a lōʻihi ke ola, a me nā noi me ke kūpaʻa kūikawā i ka haki ʻana o ke kaiapuni, e like me nā kini ʻōpala 90-galani a me nā pahu wahie mīkini liʻiliʻi, kekahi o nā hoʻohana no kēia mea.
hoʻohuli ʻana i ka hoʻoheheʻe ʻana
Ke hana ʻia nā mea me ka hoʻohana ʻana i kēia ʻenehana, ua kuʻi pinepine ʻia lākou i loko o ka pauka a laila hoʻoheheʻe ʻia a kahe i loko o kahi pōʻaiapuni wela. Hoʻohana ʻo Rotomolding i nā papa PE crosslinkable a me nā kumu maʻamau. ʻO kāna helu hoʻoheheʻe maʻamau e holo mai 3 a 8, a ʻo kona density maʻamau no MDPE/HDPEʻO ka maʻamau ma waena o 0.935 a me 0.945g/CC me kahi MWD haiki, e hāʻawi ana i ka huahana i kahi hopena kiʻekiʻe a me ka warpage liʻiliʻi. ʻAʻole kūpono nā māka MI kiʻekiʻe no ka mea ʻaʻole lākou i loaʻa ka hopena i manaʻo ʻia o nā waiwai rotomolded a me ke kūpaʻa i ka haki ʻana o ke kaiapuni.
Hoʻohana nā noi no ka rotomoulding hana kiʻekiʻe i nā ʻano kūikawā o kāna mau māka crosslinkable kemika. Loaʻa i kēia mau māka ke kūpaʻa koʻikoʻi i ka māwae koʻikoʻi o ke kaiapuni a me ka paʻakikī i ka wā mua o ke kaʻina hana hoʻoheheʻe ke kahe maikaʻi lākou. kūpaʻa i ka wā a me ka abrasion. ʻO nā pahu nui mai nā pahu mālama mahiʻai 20,000-galani a i nā pahu mālama 500-galani i hoʻohana ʻia e lawe i nā kemika like ʻole he kūpono loa ia no ka PE cross-linkable.

ʻO ka hana ʻana i ka ʻili puhi maʻamau a i ʻole ka hana ʻana i ka extrusion pālahalaha e hoʻohana pinepine ʻia i ka hana ʻana i ka ʻili PE. Hoʻohana ʻia ka hapa nui o nā PE no nā ʻili; ʻo nā koho e komo pū me ka linear low density PE (LLDPE) a i ʻole ka general-purpose low density PE (LDPE). Ke koi ʻia ka stretchability nui a me nā ʻano pale maikaʻi loa, hoʻohana pinepine ʻia nā ʻano ʻili HDPE. No ka laʻana, hoʻohana pinepine ʻia ka ʻili HDPE i loko o nā ʻeke supermarket, nā ʻeke meaʻai, a me nā ʻeke huahana.
