Ka hana ʻana o ka plastic
Plastic - ʻO ka huaʻōlelo mai ka Helene (plastikos), ʻo ia ka mea kūpono no ka hoʻoheheʻe ʻana, ʻo ia hoʻi, ka plasticity i ka hana hana, e ʻae iā lākou e hoʻolei ʻia.
Hana i nā ʻano like ʻole. Hiki ke kapa ʻia ka hana ʻana o ka plastic he masterpiece o ke kanaka i ka 20th century, ma hope o 100 mau makahiki o ka hoʻomohala ʻana, ua loaʻa ka plastic i nā wahi āpau Ua lilo ia i mea waiwai pono no ka ʻoihana civili hou.
Paxsing
ʻO "Paksin" ka mea mua i ʻike ʻia - e ulu ana i ka plastic. I ka makahiki 1850, ua noiʻi ʻo Parkes chemist English i nā ʻano hana collodion. He mea paakiki hiki ke pelu. A kapa ʻia ʻo ia ʻo 'Paksin'. ʻO ka hoʻohana ʻana iā Parkes "Paxine" i hana i nā mea āpau mai nā pulu a i nā pihi a i nā mea nani, a makemake nui nā kānaka.
celluloid
I ka makahiki 1860, ua hoʻomaikaʻi ʻo Hiatt i ke kaʻina hana o ka "Paksin" a kapa ʻia ʻo ia ʻo "Celluloid". "Ua hoʻohana mua ʻia ʻo Ceruloc i ka hana ʻana i nā pōpō biliard, akā i ka hoʻomau ʻana o ka mākeke plastik, ua hana ʻia ʻo "Ceruloc" i nā ʻano like ʻole.
Huahana. ʻO "Celluloid" he plastic i hana ʻia e ke kanaka, me nā hiʻohiʻona hiki ke ahi, no laila ua kaupalena ʻia kāna ʻano huahana.
ʻIke ʻia o ka polyethylene
I ka makahiki 1933, ua ʻike ʻo Reginald Gibson lāua ʻo Eric Fawcett o ICI e hiki ke hoʻolilo ʻia ka ethylene i polyethylene ma lalo o ke kaomi kiʻekiʻe. polyethylene(LDPE) a me ka polyethylene kiʻekiʻe (HDPE) ma nā ʻano ʻelua. I ka makahiki 1950, ua ʻike ka American Phillips Oil Company i ka chromium oxide ma ke ʻano he catalyst, hiki ke polymerized ka ethylene e hana i ka polyethylene kiʻekiʻe ma lalo o ke kaomi waena, a ua hoʻokō ʻia ka hana ʻoihana i ka makahiki 1957. a-Ua hoʻomākaukau ʻia ka māla poly (B) haʻahaʻa haʻahaʻa mai ka olefin ma ke ʻano hoʻonā. He mea maʻalahi ka PE, hiki ke hoʻopili ʻia a kū i ka ʻino kemika. Hoʻohana ʻia ʻo LDPE i ka hana ʻana i nā kiʻiʻoniʻoni a me nā mea hoʻopihapiha HDPE i hoʻohana nui ʻia e hana i nā ipu, nā paipu a me nā ʻāpana kaʻa.
Hoʻohana kā mākou hui i nā huahana polyethylene
ʻO Zhongshang huangpu guoyu plastic products factory ʻO ka ʻoihana nui o ka māhele ʻo ia ka ʻoihana plastik, akā i ke koho ʻana i nā mea e koho ai i ka polyethylene, ʻO ke kumu ʻo ia ka Polyethylene odorless, non-toxic, like me ka wax, he haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi loa (ka hoʻohana liʻiliʻi. Hiki i ka mahana ke hiki i -100 ~ -70 ° C), ke kūpaʻa kemika maikaʻi, ke kū'ē i ka nui o ka waikawa a me ka erosion alkali (ʻaʻole kū i ka waikawa me nā waiwai oxidation). ʻAʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau i ka lumi wela, ka haʻahaʻa wai haʻahaʻa, ka hoʻokaʻawale uila maikaʻi. ʻoi aku ke koʻikoʻi. Hoʻokuʻu ʻole ʻo Iapana i nā palena o ka honua i ka hoʻokuʻu ʻana i nā ʻōpala nuklea, kahi e hōʻino ai i ke kaiaola. ʻO ka mea hiki iā mākou ke hana i ka mea maikaʻi loa e pale i ke kaiapuni kahi e ola ai mākou
