I nā makahiki i hala iho nei, ua hoʻomau ka hoʻohana ʻana o nā plastics i nā kaʻa. I kēia manawa, ua hōʻea ka hoʻohana ʻana o nā plastic automotive i Kelemānia, ʻAmelika Hui Pū ʻIa, Iapana a me nā ʻāina ʻē aʻe i ka 10% a 15%, a ʻo kekahi a hiki i ka 20%. Ma ka hoʻoholo ʻana mai nā mea i hoʻohana ʻia i nā kaʻa hou, inā he ʻāpana hoʻonaninani o waho, nā ʻāpana hoʻonaninani o loko, a i ʻole nā ​​​​mea hana a me nā ʻāpana hana, hiki ke ʻike ʻia ke aka o ka hana plastic ma nā wahi āpau. A me ka hoʻomaikaʻi mau ʻana o ka paʻakikī, ikaika, a me nā waiwai tensile, ua puka mālie nā puka aniani, nā puka, nā papa a me nā kaʻa pauka a pau, a ke wikiwiki nei ka hana o ka plasticization kaʻa.

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

1.He mea maʻalahi ka hoʻoheheʻe ʻana i ka plastik, maʻalahi loa ka hana ʻana i nā ʻāpana me nā ʻano paʻakikī. Eia kekahi laʻana, i ka wā e hanaʻia ai ka mea hana me nā papa kila, pono pinepine e hana mua a hoʻohālike i nā'āpana likeʻole, a laila e hōʻuluʻulu a weld iā lākou me nā mea hoʻohui, e koi ana i nā kaʻina hana he nui. Hiki ke hoʻoheheʻe ʻia ka hoʻohana ʻana i ka plastic i ka manawa hoʻokahi, pōkole ka manawa hana, a ua hōʻoia ʻia ka pololei.

2. ʻO ka pōmaikaʻi nui loa o ka hoʻohana ʻana i nā plastics no nā mea kaʻa kaʻa e hōʻemi i ke kaumaha o ke kino kaʻa. ʻO ka māmā ka pahuhopu i hahai ʻia e ka ʻoihana kaʻa, a hiki i nā plastics ke hōʻike i ko lākou mana ma kēia ʻano. ʻO ka mea maʻamau,ʻo ka'umekaumaha kiko'ī o ka plastic he 0.9 ~ 1.5, aʻaʻole eʻoi aku ka nui o ka'umekaumaha o ka fiber-reinforced composite ma mua o 2. Ma waena o nā mea metala,ʻo ka'umekaumaha kūikawā o ke kila A3 he 7.6, he 8.4 ke keleawe, a he 2.7 ka alumini. Hoʻolilo kēia i ka plastic i mea makemake no nā kaʻa māmā.

3. ʻO nā hiʻohiʻona elastic deformation o nā huahana plastik e hoʻopili i ka nui o ka ikehu collision, ʻoi aku ka nui o ka hopena buffering i nā hopena ikaika, a pale i nā kaʻa a me nā kaʻa. No laila, hoʻohana ʻia nā panela mea hana plastik a me nā huila hoʻokele i nā kaʻa hou e hoʻonui ai i ka hopena cushioning. ʻO ka mua a me ka hope a me nā ʻāpana ʻoki kino i hana ʻia 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 plastic ka hana o ka hoʻomoʻa ʻana a me ka attenuating vibration a me ka walaʻau, hiki ke hoʻomaikaʻi i ka ʻoluʻolu o ka holo.

4. hiki ke hana ʻia nā plastics i loko o nā plastics me nā waiwai e pono ai ma o ka hoʻohui ʻana i nā mea hoʻopihapiha like ʻole, nā plasticizers a me nā mea paʻakikī e like me ke ʻano o ka plastics, a hiki ke hoʻololi ʻia ka ikaika mechanical a me ka hana ʻana a me ka hoʻoheheʻe ʻana i nā waiwai e hoʻokō i nā koi o nā ʻāpana like ʻole ma ke kaʻa. . No ka laʻana, pono e loaʻa i ka bumper ka ikaika mechanical nui, ʻoiai ʻo ka cushion a me ke kua e hana ʻia me ka polyurethane foam palupalu.

5.He kūpaʻa koʻikoʻi ko ka plastic a ʻaʻole e ʻino inā pōʻino ma ka ʻāina. Eia nō naʻe, i ka wā e poino ai ka ʻili o ka pena a ʻaʻole i hana maikaʻi ʻia ka anti-corrosion i ka hana kila, ua maʻalahi ka ʻōpala a ʻino. ʻOi aku ka ʻoi aku o ka pale ʻana o ka palaka i nā waikawa, alkalis, a me nā paʻakai ma mua o nā pā kila. Inā hoʻohana ʻia nā plastics i uhi kino, kūpono loa ia no ka hoʻohana ʻana i nā wahi me ka nui o ka haumia.

ʻO ka ʻōlelo maʻamau, ua hoʻomohala ʻia nā plastic automotive mai nā ʻāpana hoʻonaninani maʻamau i nā ʻāpana kūkulu a me nā ʻāpana hana; Ke hoʻomohala nei nā mea palaki kaʻa kaʻa i ke ala o nā mea i hoʻohui ʻia a me nā alloy plastic me ka ikaika kiʻekiʻe, ka hopena maikaʻi aʻe, a me ke kahe kiʻekiʻe. He ala lōʻihi nō ka hele ʻana no ka hoʻolaha ʻana i nā kaʻa plastik i ka wā e hiki mai ana. ʻAʻole ia he pilikia palekana wale nō, akā nā pilikia e like me ka ʻelemakule a me ka hana hou ʻana. Pono kēia e hoʻomaikaʻi hou i ka ʻenehana.
