Ka nānā 'ana i ka hana o nā mea maka no nā pallet plastik

Hana ʻia nā pallet plastik i kēia manawa me HDPE, a he ʻokoʻa nā ʻano o ka HDPE. ʻO nā hiʻohiʻona kūʻokoʻa o HDPE ka hui kūpono o nā ʻano kumu ʻehā: density, molecular weight, molecular weight distribution and additives. Hoʻohana ʻia nā catalysts e hana i nā polymers hana kūikawā. Hoʻohui ʻia kēia mau mea hoʻololi e hana i nā māka HDPE no nā kumu like ʻole, e loaʻa ai kahi kaulike i ka hana.

I ka hana maoli ʻana a me ka hana ʻana o nā pallet plastic, ʻo ka maikaʻi o kēia mau ʻano nui ka hopena i kekahi i kekahi. Ua ʻike mākou ʻo ka ethylene ka mea maka nui no ka polyethylene, a ʻo kekahi mau comonomers ʻē aʻe, e like me 1-butene, 1-hexene a i ʻole 1-octene, hoʻohana pinepine ʻia e hoʻomaikaʻi i nā waiwai polymer. No ka HDPE, ʻaʻole i ʻoi aku ka nui o ka ʻike o nā monomer liʻiliʻi ma luna o 1%-2%. ʻO ka hoʻohui ʻana o nā comonomers e hoʻemi iki i ka crystallinity o ka polymer. Hoʻololi pinepine ʻia kēia hoʻololi e ka density, a pili linearly i ka crystallinity.

ʻO ka ʻoiaʻiʻo, ʻo nā density like ʻole o HDPE e hana i nā ʻokoʻa koʻikoʻi i ka hana ʻana o nā pallet plastik i hana ʻia. ʻO ka nui o ka polyethylene medium-density (MDPE) mai ka 0.926 a i ka 0.940g/CC. Hoʻokaʻawale ʻia nā papa inoa ʻē aʻe i ka MDPE ma HDPE a i ʻole LLDPE. Loaʻa i nā Homopolymers ka mānoanoa kiʻekiʻe loa, ka ʻoʻoleʻa, ka impermeability maikaʻi a me ka helu heheʻe kiʻekiʻe.

ʻO ka maʻamau i ka hana ʻana i nā pallet plastik, pono pinepine kekahi mau mea hoʻohui e hōʻoia i ka hana pono. Pono nā hoʻohana kikoʻī i nā ʻano hoʻohui kūikawā, e like me ka hoʻohui ʻana o nā antioxidants e pale i ka polymer degradation i ka wā e hana ai a pale i ka oxidation o ka huahana i hoʻopau ʻia i ka wā hoʻohana. Hoʻohana ʻia nā mea hoʻohui antistatic i nā māka hōʻailona he nui e hōʻemi i ka hoʻopili ʻana o ka lepo a me ka lepo i nā ʻōmole a i ʻole ka pahu.

Eia kekahi, i mea e hōʻoiaʻiʻo ai i ka maikaʻi o nā pallet plastic, pono e uku nui ʻia i ka hoʻopili ʻana a me ka mālama ʻana i nā mea maka. ʻO ka maʻamau i ka wā e mālama ai i nā mea HDPE, pono e haʻalele i nā kumu ahi, insulated, a mālama ʻia ka hale kūʻai i maloʻo a maʻemaʻe. Ua papa loa ia ka hui pu ana i na mea haumia, a ua kapu loa i ka la a me ka ua. Eia kekahi, i ka wā o ka lawe ʻana, pono e mālama ʻia i loko o kahi kaʻa maʻemaʻe, maloʻo a uhi ʻia a i ʻole ka hale, ʻaʻole pono e ʻae ʻia nā mea ʻoi e like me nā kui.
