ʻEhā mau alakaʻi anti-aging e pono ai ʻoe e ʻike e pili ana i nā mīkini extrusion plastic

Hoʻohana nui ʻia nā mea Polymer i kēia manawa ma nā ʻano he nui e like me ka hana ʻana i nā mea kiʻekiʻe, ka ʻike uila, ka halihali, ka mālama ʻana i ka ikehu hale, ka aerospace, ka pale kaua aupuni a me ka ʻoihana koa ma muli o ko lākou mau waiwai maikaʻi loa e like me ke kaumaha māmā, ka ikaika kiʻekiʻe, ke kūpaʻa i ka mahana a me ke kūpaʻa i ka pala. ʻAʻole wale kēia e hāʻawi i kahi mākeke ākea no ka ʻoihana mea polymer hou, akā ke kau nei hoʻi i nā koi kiʻekiʻe aʻe ma kāna hana maikaʻi, ka pae hilinaʻi a me ka hiki ke hōʻoia.

No laila, pehea e hoʻonui ai i ka hana o nā huahana mea polymer e like me nā kumumanaʻo o ka mālama ikehu, ka haʻahaʻa kalapona a me ka hoʻomohala ʻana i ke kaiapuni e hopohopo nui nei. ʻO ka ʻelemakule kahi mea nui i ka hilinaʻi a me ke kūpaʻa o nā mea polymer.
A laila e nānā mākou i ke ʻano o ka polymer ageing, nā ʻano o ka ʻelemakule, nā kumu e hoʻokumu ai, nā ʻano nui o ka anti-aging a me ka anti-aging o nā ʻelima maʻamauKa lula ea Ke.

I. Ka ʻelemakule ʻana o ka plastik
ʻO nā ʻano hoʻonohonoho a me ke kūlana kino o nā mea polymer a me kā lākou mau mea o waho e like me ka wela, ka mālamalama, ka oxygen wela, ka ozone, ka wai, ka waikawa, ka alkali, ka bacteria a me nā enzymes i ke kaʻina hana e hoʻolilo iā lākou i mea hōʻemi a nalowale paha ka hana i ke kaʻina hana o ka noi.
ʻAʻole wale kēia e alakaʻi ai i ka hoʻonele ʻana i nā kumuwaiwai a me nā pōʻino nui aʻe ma muli o kā lākou hana ʻole ʻana, akā ʻo ka palaho ʻana o nā mea i hoʻokumu ʻia e ko lākou ʻelemakule ʻana e hiki ke hoʻohaumia i ke kaiapuni. ʻO ka ʻelemakule ʻana o nā mea polymer i ka wā e hoʻohana ʻia ai he hiki ke hana i nā pōʻino nui a me nā pōʻino hiki ʻole ke hoʻoponopono hou ʻia.
No laila, ua lilo ka anti-kahiko ʻana o nā mea polymer i mea e pono ai ka ʻoihana polymer e hoʻoponopono.

II. Nā ʻano o ka ʻelemakule polymer
Ma muli o nā ʻano like ʻole o nā polymers a me nā kūlana hoʻohana like ʻole, aia nā ʻano ʻelemakule like ʻole a me nā ʻano. Ma keʻano laulā, hiki ke hoʻokaʻawale ʻia ka ʻelemakule ʻana o nā mea polymer i nā ʻano loli ʻehā e hiki mai ana.

01 Nā loli i ke ʻano
Nā ʻili, nā kiko, ke kala kālā, nā māwae, ka hau ʻana, ka ʻōʻō ʻana o ka pepa kala, ka pipili ʻana, ka piʻo ʻana, nā maka iʻa, ka ʻūmiʻi ʻana, ka emi ʻana, ka wela ʻana, ka hoʻopilikia ʻana o ka maka a me nā loli i ke kala maka.

02 Nā loli i nā waiwai kino
Nā loli i ka solubility, ka pehu ʻana, nā waiwai rheological, ke kūpaʻa anu, ke kūpaʻa wela, ka permeability wai, ka permeability ea, a pēlā aku.

03 Nā loli i nā waiwai mechanical
Nā loli i ka ikaika tensile, ka ikaika kulou, ka ikaika shear, ka ikaika hopena, ka elongation pili, ka hoʻomaha ʻana o ke koʻikoʻi, a pēlā aku.

04 Nā loli i nā waiwai uila
E like me nā loli i ke kūpaʻa o ka ʻili, ke kūpaʻa leo, ka dielectric constant, ka ikaika o ka haki uila, a pēlā aku.

III. Ka nānā ʻana o ka microscopic o ka ʻelemakule ʻana o nā mea polymeric
Hoʻokumu nā polymers i nā molekala i hoʻonāukiuki ʻia ma lalo o ka hana a ka wela a i ʻole ka mālamalama. Ke lawa ka ikehu, 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 hoʻoulu ʻana i ka degradation, a hiki nō hoʻi ke hana i ka cross-linking.
Inā loaʻa ka oxygen a i ʻole ka ozone i ke kaiapuni, hoʻoulu ʻia kekahi mau hopena oxidation, e hana ana i nā hydroperoxides (ROOH) a me ka hoʻokaʻawale hou ʻana i nā hui carbonyl.
Inā he mau ion metala catalyst i koe i loko o ka polymer, a inā lawe ʻia mai nā ion 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 hoʻolalelale kēia i ka hoʻohaʻahaʻa oxidative o ka polymer.

IV. Nā ʻano hana nui e hoʻomaikaʻi ai i ka hana anti-kahiko

I kēia manawa, ʻo nā ʻano hana nui e hoʻomaikaʻi a hoʻoikaika i ka hana anti-kahiko o nā mea polymer nā ʻehā.

01 Palekana kino (mānoanoa, pena ʻana, hui papa waho, a pēlā aku)
ʻO ka ʻelemakule ʻana o nā mea polymer, ʻoiai ka ʻelemakule photo-oxidative, hoʻomaka mua mai ka ʻili o ka mea a i ʻole ka huahana, e hōʻike ana ma ke ʻano he discoloration, chalking, cracking, nalowale o ka gloss, a pēlā aku, a laila e hele mālie i loko. ʻOi aku ka maʻalahi o nā huahana lahilahi e hāʻule mua ma mua o nā huahana mānoanoa, no laila hiki ke hoʻolōʻihi ʻia ke ola o ka huahana ma ka hoʻomānoanoa ʻana i ka huahana.
No nā huahana i maʻalahi i ka ʻelemakule, hiki ke hoʻopili ʻia kahi uhi kū i ka wā ma luna o ka ʻili, a i ʻole hiki ke hoʻopili ʻia kahi mea kū i ka wā i ka papa waho o ka huahana, e hoʻopili ana i kahi papa pale i ka ʻili o ka huahana, a laila e hoʻopaneʻe ana i ke kaʻina hana ʻelemakule.

02 Hoʻomaikaʻi ʻia ka hana ʻana
He nui nā mea i pilikia i nā pilikia ʻelemakule i ka wā o ke kaʻina hana synthesis a i ʻole ka hoʻomākaukau ʻana. No ka laʻana, ka mana o ka wela i ka wā o ka polymerization, ka ʻelemakule thermal a me ka oxygen i ka wā o ka hana ʻana, a pēlā aku. A laila, e like me ia, hiki ke hoʻēmi ʻia ka mana o ka oxygen ma ka hoʻohui ʻana i nā mea deaerating a i ʻole nā ​​​​mea hoʻoneʻe i ka wā o ka polymerization a i ʻole ka hana ʻana.
Eia nō naʻe, hiki i kēia ʻano hana ke hōʻoiaʻiʻo i ka hana o ka mea ma ka hale hana wale nō, a hiki ke hoʻokō ʻia mai ke kumu o ka hoʻomākaukau ʻana o ka mea a ʻaʻole hiki ke hoʻoponopono i ka pilikia o kona ʻelemakule ʻana i ka wā o ka hana hou ʻana a me ka hoʻohana ʻana.

03 Hoʻolālā kūkulu a hoʻololi paha i nā mea
He nui nā mea polymer i loaʻa nā pūʻulu i loko o ko lākou ʻano molekala i maʻalahi i ka ʻelemakule, no laila ʻo ka hoʻolālā ʻana o ke ʻano molekala o ka mea e pani i nā pūʻulu maʻalahi i ka ʻelemakule me nā pūʻulu ʻaʻole i ʻelemakule hiki ke loaʻa pinepine kahi hopena maikaʻi.

04 Hoʻohui i nā mea hoʻohui anti-kahiko
I kēia manawa, ʻo kahi ala kūpono a maʻamau e hoʻomaikaʻi ai i ke kūpaʻa ʻana o nā mea polymer i ka wā ʻelemakule, ʻo ia ka hoʻohui ʻana i nā mea hoʻohui anti-kahiko, kahi i hoʻohana nui ʻia ma muli o ko lākou kumukūʻai haʻahaʻa a me ka ʻoiaʻiʻo ʻaʻole pono lākou i nā hoʻololi i nā kaʻina hana e kū nei. Hiki ke hoʻohui ʻia kēia mau mea hoʻohui anti-kahiko ma nā ʻano nui ʻelua.

Hoʻohui pololei ʻia ka mea hoʻohui anti-kahiko (pauka a wai paha) me ka resin a me nā mea maka ʻē aʻe a laila hoʻopuka ʻia a granulated a injected paha, a pēlā aku. He ala maʻalahi a maʻalahi hoʻi kēia o ka hoʻohui ʻana, kahi i hoʻohana nui ʻia e nā mea hana pelletizing a me nā injection molding.
