Hoʻohana nui ʻia nā mea polymer i kēia manawa i ka hana kiʻekiʻe, ka ʻike uila, ka lawe ʻana, ka mālama ʻana i ka ikehu, aerospace, ka pale aupuni a me nā ʻano ʻē aʻe he nui ma muli o ko lākou mau waiwai maikaʻi loa e like me ke kaumaha māmā, ka ikaika kiʻekiʻe, ke kūpaʻa wela a me ka pale ʻana i ka corrosion. ʻAʻole wale kēia e hāʻawi i kahi ākea ākea no ka ʻoihana mea polymer hou, akā hāʻawi pū i nā koi kiʻekiʻe no kāna hana maikaʻi, pae hilinaʻi a me ka hiki ke hōʻoia.
No laila, pehea e hoʻonui ai i ka hana o nā huahana polymer material e like me ke kumu o ka mālama ʻana i ka ikehu, ke kalapona haʻahaʻa a me ka hoʻomohala ʻana i ka ecological e hoʻonui nui ʻia. A he mea nui ka ʻelemakule e pili ana i ka hilinaʻi a me ka lōʻihi o nā mea polymer.
Ma hope aʻe, e nānā mākou i ke ʻano o ka ʻelemakule o nā mea polymer, nā ʻano ʻelemakule, nā mea e hoʻoulu ai i ka ʻelemakule, nā ala nui o ka anti-aging a me ka anti-aging o ʻelima plastics maʻamau.
A. ʻelemakule palaki
ʻO nā hiʻohiʻona a me ke kūlana kino o nā mea polymer ponoʻī a me kā lākou mau mea i waho e like me ka wela, ka māmā, ka oxygen thermal, ka ozone, ka wai, ka waikawa, ka alkali, ka bacteria a me nā enzymes i ke kaʻina o ka hoʻohana ʻana e hoʻolilo iā lākou i lalo o ka hoʻohaʻahaʻa a i ʻole ka nalowale i ka hana. o ka noi.
ʻAʻole wale kēia e hoʻopau wale i nā kumuwaiwai, a hiki paha ke kumu i nā pōʻino nui aʻe ma muli o kāna hana ʻole ʻana, akā ʻo ka decomposition o nā mea i hana ʻia e kona ʻelemakule hiki ke hoʻohaumia i ke kaiapuni.
ʻO ka ʻelemakule o nā mea polymer i ke kaʻina o ka hoʻohana ʻana i ʻoi aku ka nui o nā pōʻino nui a me nā poho hiki ʻole ke hoʻoponopono ʻia.
No laila, ua lilo ka anti-aging o nā mea polymer i pilikia e pono ai ka ʻoihana polymer e hoʻoponopono.
B. Nā ʻano o nā mea polymer kahiko
He ʻokoʻa nā hiʻohiʻona a me nā hiʻohiʻona ma muli o nā ʻano polymer like ʻole a me nā kūlana hoʻohana like ʻole. Ma ka laulā, hiki ke hoʻokaʻawale ʻia ka ʻelemakule o nā mea polymer i nā ʻano hoʻololi ʻehā.
01 Hoʻololi i ka helehelena
ʻO nā ʻōpala, nā kiko, nā laina kālā, nā māwae, ka hau hau, ka ʻulaʻula, ka paʻa, ka ʻāʻī ʻana, ka maka iʻa, ka mimino, ka mimi ʻana, ka ʻā, ka distortion optical a me ka hoʻololi ʻana o ka waihoʻoluʻu.
02 Hoʻololi i nā waiwai kino
Me ka solubility, ka pehu, nā waiwai rheological a me nā loli i ke kūpaʻa anuanu, ka pale wela, ka wai permeability, ka ea permeability a me nā waiwai ʻē aʻe.
03 Hoʻololi i nā waiwai mechanical
Hoʻololi i ka ikaika tensile, ikaika kulou, ikaika shear, ikaika hopena, elongation pili, hoʻomaha hoʻomaha a me nā waiwai ʻē aʻe.
04 Hoʻololi i nā waiwai uila
E like me ka pale ʻana o ka ʻili, ka nui o ke kūpaʻa, ka dielectric mau, ka ikaika haʻihaʻi uila a me nā loli ʻē aʻe.
C. Ke kālailai microscopic o ka wā kahiko o nā mea polymer
Hoʻokumu nā Polymers i nā ʻano molekole i ke alo o ka wela a i ʻole ka māmā, a ke kiʻekiʻe ka ikehu, ua haki nā kaulahao molekala e hana i nā radical manuahi, hiki ke hana i nā hopena kaulahao i loko o ka polymer a hoʻomau i ka hoʻomaka ʻana i ka hoʻohaʻahaʻa ʻana a hiki ke hoʻoulu i ka cross- pili ana.
Inā loaʻa ka oxygen a i ʻole ka ozone i loko o ke kaiapuni, ua hoʻoulu ʻia kekahi ʻano o nā hopena oxidation, e hana ana i nā hydroperoxides (ROOH) a me ka decomposing hou i nā hui carbonyl.
Inā loaʻa nā koena metala catalyst i loko o ka polymer, a i ʻole inā lawe ʻia nā iona metala e like me ke keleawe, ka hao, ka manganese a me ka cobalt i ka wā e hana ai a hoʻohana ʻia paha, e hoʻokē ʻia ka hopena degradation oxidative o ka polymer.
D. ʻO ke ala nui e hoʻomaikaʻi ai i ka hana anti-aging
I kēia manawa, ʻehā mau ala nui e hoʻomaikaʻi a hoʻomaikaʻi i ka hana anti-aging o nā mea polymer penei.
01 Ka pale kino (ka mānoanoa, pena, ka papa o waho, etc.)
ʻO ka ʻelemakule o nā mea polymer, ʻoi aku ka nui o ka photo-oxidative aging, e hoʻomaka ana mai ka ʻili o nā mea a i ʻole nā huahana, i hōʻike ʻia e like me ka discoloration, chalking, cracking, gloss reduced, etc., a laila hele mālie i ka loko. ʻOi aku ka maikaʻi o nā huahana lahilahi ma mua o nā huahana mānoanoa, no laila hiki ke hoʻonui ʻia ke ola lawelawe o nā huahana ma ka mānoanoa o nā huahana.
No nā huahana kūpono i ka wā kahiko, hiki ke hoʻopili ʻia kahi ʻāpana o ka uhi ʻana i ka wā ma luna o ka ʻili, a i ʻole e hoʻohui ʻia kahi papa o nā mea kū i ka wā ma ka ʻaoʻao o waho o nā huahana, i hiki ke hoʻopili ʻia kahi papa pale. ka ʻili o nā huahana e hoʻolohi i ke kaʻina hana kahiko.
02 Hoʻomaikaʻi i ka ʻenehana hana
Nui nā mea i loko o ka synthesis a i ʻole ka hoʻomākaukau ʻana, aia kekahi pilikia o ka ʻelemakule. No ka laʻana, ka mana o ka wela i ka wā polymerization, ka wela a me ka oxygen aging i ka wā o ka hoʻoili ʻana, a me nā mea ʻē aʻe.
Eia nō naʻe, hiki i kēia ala ke hōʻoiaʻiʻo i ka hana o ka mea ma ka hale hana, a hiki ke hoʻokō ʻia kēia ʻano mai ke kumu o ka hoʻomākaukau ʻana i nā mea, a ʻaʻole hiki ke hoʻopau i kona pilikia ʻelemakule i ka wā o ka hana hou ʻana a me ka hoʻohana ʻana.
03 Hoʻolālā hale a hoʻololi paha i nā mea
Nui nā mea macromolecule i nā hui kahiko i loko o ka molecular structure, no laila ma o ka hoʻolālā ʻana o ka molecular structure o ka mea, hoʻololi i nā pūʻulu ʻelemakule me nā pūʻulu ʻelemakule hiki pinepine ke pāʻani i kahi hopena maikaʻi.
04 Hoʻohui i nā mea hoʻohui anti-aging
I kēia manawa, ʻo ke ala kūpono a me ke ʻano maʻamau e hoʻomaikaʻi ai i ka pale ʻana o ka ʻelemakule o nā mea polymer ʻo ia ka hoʻohui ʻana i nā mea hoʻohui anti-aging, i hoʻohana nui ʻia no ka haʻahaʻa haʻahaʻa a ʻaʻole pono e hoʻololi i ke kaʻina hana e kū nei. ʻElua mau ala nui e hoʻohui i kēia mau mea hoʻohui anti-aging.
ʻO nā mea hoʻohui anti-aging (pauka a wai) a me ka resin a me nā mea maka'ē aʻe i hui ponoʻia a hui pūʻia ma hope o ka extrusion granulation a injection molding, a me nā mea'ē aʻe. mea kanu hoolei injection.
