Nā pōmaikaʻi o ka ea
Maʻalahi e hana, maʻalahi e hana (maʻalahi e hoʻohālikelike)
ʻOiai ʻoi aku ka paʻakikī o ka geometry o ka huahana, ke hiki ke hoʻokuʻu ʻia mai ka punahelu, maʻalahi ka hana ʻana. No laila, ʻoi aku ka maikaʻi o kāna pono ma mua o ka hana metala, ʻoi aku nā huahana hoʻoheheʻe. Ma hope o ke kaʻina hana, hiki ke hana i kahi huahana hoʻopau paʻakikī loa.
Hiki ke kala manuahi e like me nā pono, a i ʻole i hana ʻia i nā huahana aniani moakaka
Hiki ke hoʻohana i nā Plastics e hana i nā huahana kala, aniani a nani, a hiki ke kala ʻia i ka makemake, kahi e hoʻonui ai i kā lākou waiwai kūʻai a hāʻawi i ka poʻe i kahi manaʻo ʻulaʻula.
Hiki ke hana i nā huahana māmā a me ka ikaika nui
Hoʻohālikelike ʻia me nā huahana metala a me ka pālolo, he māmā kona kaumaha, ʻoi aku ka maikaʻi o nā mīkini, a me ka ikaika kikoʻī kiʻekiʻe aʻe (ka lakio o ka ikaika i ka nui), no laila hiki ke hana ʻia i nā huahana māmā a kiʻekiʻe ikaika. ʻOi aku ma hope o ka hoʻopihapiha ʻana i ka fiber aniani, hiki ke hoʻomaikaʻi ʻia kona ikaika.
Hoʻohui, no ka mea, māmā nā plastik i ke kaupaona a hiki ke mālama i ka ikehu, e māmā ana kā lākou huahana.
ʻAʻohe pala a popopo
Kūleʻa ka Plastics i ka hoʻowahāwahā ʻia e nā kemika like ʻole a ʻaʻole e pala a popopo hoʻi e like me ka maʻalahi. ʻAʻohe pono e hopohopo e pili ana i ka luku ʻia ʻana o ka waikawa, alkali, paʻakai, ʻaila, lāʻau lapaʻau, wai a me ka pala i ka hoʻohana ʻana ia.
ʻAʻole maʻalahi e hoʻolilo i ka wela, hana hoʻowalewale maikaʻi
Ma muli o ka wela kikoʻī nui a me ka haʻahaʻa conductivity wela o ka ea, ʻaʻole maʻalahi ia e hoʻolilo i ka wela, no laila maikaʻi ka mālama ʻana i ka wela a me ka hopena hoʻoluʻu wela.
Hiki iā ia ke hana i nā ʻāpana conductive a me nā huahana insulate
ʻO ka pīpī ponoʻī kahi mea hoʻopili maikaʻi loa. I kēia manawa, hiki ke ʻōlelo ʻia ʻaʻohe huahana uila i hoʻohana ʻole i ka palaka. Eia nō naʻe, inā hoʻopiha ʻia ka ea i ka pauka metala a i ʻole nā ʻōpala no ka hoʻoheheʻe ʻana, hiki ke hana ʻia i huahana me ka hoʻoliʻiliʻi uila maikaʻi.
ʻO ke kūpikipiki maikaʻi loa a me ka hana hoʻohaʻahaʻa leo, lawe maikaʻi kukui maikaʻi
Loaʻa i nā Plastics i ka lūlū maikaʻi a me nā waiwai hōʻemi walaʻau; hiki ke hoʻohana i nā plastics aniani moakaka (e like me PMMA, PS, PC, a me nā mea ʻē aʻe) e hana i nā huahana uila aniani (e like me nā aniani, nā hōʻailona, nā papa uhi, a pēlā aku.).
Kālā hana haʻahaʻa
ʻOiai ʻaʻohe kumu kūʻai o nā mea pono ponoʻī, no ka mea maʻalahi ka hana ʻana o ka plastic a haʻahaʻa iki ke kumukūʻai, hiki ke hoʻemi ʻia ke kumukūʻai huahana.
Nā mea maikaʻi ʻole o ka plastic
Kūlana wela maikaʻi ʻole a maʻalahi hoʻi e wela
ʻO kēia ka hōʻino nui loa o nā lula. Ke hoʻohālikelike ʻia me nā huahana metala a me nā aniani, ʻoi aku ka haʻahaʻa o kona kūpaʻa wela. ʻOi aku ke kiʻekiʻe o ka mahana, e deform ia, a maʻalahi hoʻi e wela. Ke puhi, hiki i ka hapa nui o nā lula ke hoʻoulu i ka nui o ka wela, ka uahi a me nā kinoea ʻawahia; ʻoiai no nā kēpau thermosetting, e puhi ʻo ia a peel ke ʻoi aku ia ma mua o 200 kekelē Celsius.
Ke hoʻololi nei ka mahana, e loli nui nā waiwai
Hele ia me ka ʻōlelo ʻole o ke ana wela kiʻekiʻe, ʻoiai inā hālāwai ia me ka mahana haʻahaʻa, e loli nui nā ʻano like ʻole.
Ka ikaika mīkini haʻahaʻa
Ke hoʻohālikelike ʻia me ka nui o ka metala, ʻoi aku ka haʻahaʻa o ka ikaika mechanical, no nā huahana lahilahi, maopopo leʻa kēia ʻokoʻa.
Maʻa mau i ka popopo e nā mea hoʻoheheʻe a me nā kemika kūikawā
'Lelo maʻamau, ʻoi aku ka maʻalahi o ka palaka i ka hoʻowahā ʻana o ka kemika, akā ʻo kekahi mau mea pālolo (e like me: PC, ABS, PS, a me nā mea ʻē aʻe) he waiwai maikaʻi ʻole loa i kēia mea; i mau, kūpaʻa thermosetting resins i ka popopo.
Kūlana maikaʻi ʻole a me ka ʻelemakule maʻalahi
He ikaika paha ia, ʻili a i ʻole transparency, ʻaʻole paʻa, a kolo ma lalo o ka ukana. Hoʻohui, makaʻu nā plastics āpau i nā kukuna ultraviolet a me ka lā, a e ʻelemakule ma lalo o ka hana o ke kukui, oxygen, wela, wai a me ka lewa.
Hoʻopilikia i ka hōʻino, lepo a me ka lepo
ʻO ka paakiki o nā plastics he haʻahaʻa a maʻalahi ia e hōʻino ʻia; i ka hoʻohui, no ka mea he insulator ia, uku ʻia ia electrostatically, no laila maʻalahi ka hoʻowahāwahā ʻia me ka lepo.
ʻO ke kūpaʻa dimensional maikaʻi ʻole
Ke hoʻohālikelike ʻia me ka metala, he kiʻekiʻe shrinkage o ka plastic, no laila paʻakikī e hōʻoia i ka pololei dimensional. I ke kumu o ka pulu, lawe i ka pulu a i ʻole hoʻololi i ke ana wela i ka manawa o ka hoʻohana, maʻalahi ka nui i ka manawa.
