Nūhou ʻOihana

I nā makahiki i hala iho nei, ua hoʻomau ka hoʻohana ʻana i nā plastik i nā kaʻa. I kēia manawa, ua hiki aku ka hoʻohana ʻana i nā plastik kaʻa ma Kelemania, ʻAmelika Hui Pū ʻIa, Iapana a me nā ʻāina ʻē aʻe i ka 10% a i ka 15%, a ua hiki aku kekahi ma mua o 20%. Ma muli o nā mea i hoʻohana ʻia i nā kaʻa hou, inā he mau ʻāpana hoʻonaninani o waho, nā ʻāpana hoʻonaninani o loko, a i ʻole nā ​​ʻāpana hana a me ke kūkulu ʻana, hiki ke ʻike ʻia ke aka o ka hana plastik ma nā wahi āpau. A me ka hoʻomaikaʻi mau ʻana o ka paʻakikī, ka ikaika, a me nā waiwai tensile o nā plastik ʻenekinia, ua ʻike mālie ʻia nā puka makani plastik, nā puka, nā mōlina a me nā kaʻa plastik āpau, a ke wikiwiki nei ke kaʻina hana o ka plasticization kaʻa.

He aha nā pōmaikaʻi o ka hoʻohana ʻana i ka plastic e like me nā mea hana kaʻa?

1.He maʻalahi ka hoʻoheheʻe ʻana i ka palakika, e maʻalahi ai ka hana ʻana i nā ʻāpana me nā ʻano paʻakikī. No ka laʻana, i ka wā e hana ʻia ai ka panela mea hana me nā papa kila, pono pinepine e hana mua a hoʻoponopono i nā ʻāpana like ʻole, a laila e hōʻuluʻulu a hoʻopaʻa paha iā lākou me nā mea hoʻohui, kahi e pono ai nā kaʻina hana he nui. Hiki ke hoʻoheheʻe ʻia ka hoʻohana ʻana i ka palakika i hoʻokahi manawa, pōkole ka manawa hana, a ua hōʻoia ʻia ka pololei.

2. ʻO ka pōmaikaʻi nui o ka hoʻohana ʻana i nā plastics no nā mea kaʻa, ʻo ia ka hoʻemi ʻana i ke kaumaha o ke kino o ke kaʻa. ʻO ka māmā ka pahuhopu i alualu ʻia e ka ʻoihana kaʻa, a hiki i nā plastics ke hōʻike i ko lākou mana ma kēia ʻano. Ma ke ʻano laulā, ʻo ke kaumaha kikoʻī o ka plastic he 0.9 ~ 1.5, a ʻo ke kaumaha kikoʻī o nā mea hui i hoʻoikaika ʻia i ka fiber ʻaʻole e ʻoi aku ma mua o 2. Ma waena o nā mea metala, ʻo ke kaumaha kikoʻī o ke kila A3 he 7.6, ʻo ke keleawe he 8.4, a ʻo ka alumini he 2.7. ʻO kēia ka mea e makemake ai nā plastics no nā kaʻa māmā.

3. ʻO nā ʻano hoʻololi elastic o nā huahana plastik e omo i ka nui o ka ikehu collision, loaʻa ka hopena buffering nui aʻe i nā hopena ikaika, a pale i nā kaʻa a me nā mea holo. No laila, hoʻohana ʻia nā panela mea hana plastik a me nā huila hoʻokele i nā kaʻa hou e hoʻonui i ka hopena cushioning. Hana ʻia nā bumpers mua a me hope a me nā ʻāpana trim kino i nā mea plastik e hōʻemi i ka hopena o nā mea ma waho o ke kaʻa i ke kani o ke kaʻa. Eia kekahi, loaʻa i ka plastik ka hana o ka omo ʻana a me ka hoʻēmi ʻana i ka haʻalulu a me ka walaʻau, hiki ke hoʻomaikaʻi i ka ʻoluʻolu o ka holo ʻana.

4. Hiki ke hana ʻia nā palakiko i loko o nā palakiko me nā waiwai e pono ai ma ka hoʻohui ʻana i nā mea hoʻopihapiha like ʻole, nā mea hoʻopili palakiko a me nā mea paʻakikī e like me ke ʻano o nā palakiko, a hiki ke hoʻololi ʻia ka ikaika mechanical a me nā waiwai hana a me ke kālai ʻana o nā mea e hoʻokō ai i nā koi o nā ʻāpana like ʻole ma ke kaʻa. No ka laʻana, pono ka bumper i ka ikaika mechanical nui, ʻoiai ʻo ka uluna a me ke kua e hana ʻia me ka huʻa polyurethane palupalu.

5.He kūpaʻa ikaika ko ka palakiko i ka ʻōpala a ʻaʻole ia e pala inā hōʻino ʻia ma kahi kokoke. Eia nō naʻe, i ka wā e hōʻino ʻia ai ka ʻili pena a ʻaʻole hana maikaʻi ʻia ka anti-corrosion i ka hana kila, he maʻalahi ke pala a me ka pala. ʻOi aku ka nui o ke kūpaʻa o nā palakiko i ka palakiko i nā waikawa, alkalis, a me nā paʻakai ma mua o nā papa kila. Inā hoʻohana ʻia nā palakiko ma ke ʻano he uhi kino, kūpono loa lākou no ka hoʻohana ʻana ma nā wahi me ka haumia nui.

Ma ke ʻano laulā, ua ulu aʻe nā plastik kaʻa mai nā ʻāpana hoʻonaninani maʻamau i nā ʻāpana kūkulu a me nā ʻāpana hana; ke ulu nei nā mea plastik kaʻa ma ke ala o nā mea i hui pū ʻia a me nā mea hoʻohui plastik me ka ikaika kiʻekiʻe, ka hopena maikaʻi aʻe, a me ke kahe kiʻekiʻe loa. He lōʻihi ke ala e hele ai no ka hoʻolaha ʻana i nā kaʻa plastik i ka wā e hiki mai ana. ʻAʻole ia he pilikia palekana wale nō, akā he mau pilikia e like me ka ʻelemakule a me ka hana hou ʻana. Pono e hoʻomaikaʻi hou ʻia kēia i ka ʻenehana.
