Ke Kaʻina Hana Hana ʻana o ka Fluoropolymer Plastic a me kāna Hoʻohana ʻana ma nā Kaiapuni Koʻikoʻi
Pendahuluan
ʻO nā plastik Fluoropolymer kahi hui o nā hui polymer e loaʻa ana nā ʻātoma fluorine i loko o ko lākou ʻano. ʻO Fluorine kekahi o nā mea ikaika loa i ka papa periodic, e hāʻawi ana i nā fluoropolymers i kekahi mau waiwai kū hoʻokahi e kūpono ai lākou no nā noi ma nā ʻano ʻino. Ma kēia ʻatikala, e kūkākūkā mākou i ke kaʻina hana hana o nā plastik fluoropolymer a me kā lākou mau noi like ʻole i nā ʻano paʻakikī.
Kaʻina Hana Hana Palakiko Fluoropolymer
1. Koho Monomer
Hoʻomaka ke kaʻina hana o ka hana ʻana i nā fluoropolymers me ke koho ʻana i kahi monomer kūpono. He mau mole liʻiliʻi nā Monomers e hiki ke hui pū e hana i nā polymers. I ke ʻano o nā fluoropolymers, ʻo nā monomers i hoʻohana pinepine ʻia ʻo tetrafluoroethylene (TFE), vinylidene fluoride (VDF), a me chlorotrifluoroethylene (CTFE).
2. Hoʻohuihui
A laila hele mai ke kaʻina hana polymerization, kahi e hui pū ai nā monomers e hana i nā kaulahao polymer. Aia kekahi mau ʻano polymerization i hoʻohana pinepine ʻia:
– Emulsion Polymerization: Ma kēia ʻano hana, ua hui pū ʻia ka monomer, ka wai, ka surfactant, a me ka mea hoʻomaka polymerization i loko o kahi reactor pressurized. Hoʻopuka kēia kaʻina hana i nā ʻāpana polymer micron-sized i hoʻokuʻu ʻia i loko o ka wai, e hana ana i kahi emulsion.
– Polymerization Solution: Hoʻoheheʻe ʻia nā Monomers i loko o kahi solvent organik a laila polymerized me ka hoʻohana ʻana i kahi mea hoʻomaka radical manuahi. Hoʻohana pinepine ʻia kēia e hana i nā fluoropolymers viscosity kiʻekiʻe.
– Gaseous Polymerization (I loko o ke Kinoea): Pili kēia ʻenehana i ka hoʻohui ʻana i nā monomers i loko o ke kahua kinoea. Hoʻohana pinepine ʻia ia i ka hana ʻana o ka polytetrafluoroethylene (PTFE), kekahi o nā fluoropolymers kaulana loa.
3. Ka Hana ʻana a me ka Hoʻololi ʻana
Ma hope o ka polymerization, pono ka hana ʻana a me ka hoʻololi ʻana i ka polymer maka. Hiki i kēia hana ke komo i ka extrusion, molding, a me ka uhi ʻana. Hiki ke hoʻohui ʻia nā Fluoropolymers me nā mea hoʻohui ʻē aʻe e hoʻomaikaʻi i ko lākou mau waiwai mechanical a hoʻonui paha i ke kūpaʻa wela.
4. Hoʻouluulu ʻana
Pono kekahi mau fluoropolymers i kahi kaʻina hana vulcanization e hoʻonui i ko lākou ikaika a me ke kūpaʻa. Pili ka Vulcanization i kahi kaʻina hana kemika e hana i nā loulou kea ma waena o nā kaulahao polymer, e hoʻonui ana i ke kū'ē ʻana i nā mahana kiʻekiʻe a me nā kemika huhū.
5. Hoʻāʻo Kūlana
Ma hope o ka hana ʻana o ka fluoropolymer, ʻo ke kahua koʻikoʻi aʻe ka hoʻāʻo ʻana i ka maikaʻi. Hoʻokomo kēia hoʻāʻo ʻana i ka nānā ʻana i nā waiwai kino, mechanical, a me ke kemika o ka polymer e hōʻoia i ka hoʻokō ʻana me nā kikoʻī i makemake ʻia. Hana ʻia nā hoʻāʻo no ke kūʻē ʻana i nā kemika, nā mahana koʻikoʻi, a me nā mana o ke kaiapuni e loiloi i ka hana a ka fluoropolymer ma lalo o nā kūlana koʻikoʻi.
Nā Hoʻohana ʻana o nā Plastics Fluoropolymer ma nā Kaiapuni Koʻikoʻi
1. ʻOihana Kemika
I loko o ka ʻoihana kemika, he mea maʻamau nā wahi koʻikoʻi e like me ke kiʻekiʻe o ka mahana, nā kemika ʻino, a me nā kaomi kiʻekiʻe. Hoʻohana pinepine ʻia nā Fluoropolymers e like me ka PTFE (Teflon) e hana i nā sila, nā gasket, a me nā paipu e kūʻē i nā kemika huhū a me nā mahana kiʻekiʻe loa.
2. ʻOihana ʻAila a me ke Kinoea
I loko o ka ʻoihana aila a me ke kinoea, hoʻohana ʻia nā fluoropolymers i nā noi subsea a me ka wili ʻana ma muli o ko lākou kūpaʻa ʻana i ke kaomi nui a me ka pala. Hoʻohana ʻia nā Fluoropolymers i ka hana ʻana i nā uhi pale ma nā paipu a me nā lako wili e hōʻemi i ka friction a pale i ka hōʻino.
3. ʻOihana Uila
Hoʻohana pinepine ʻia nā Fluoropolymers e like me FEP (fluorinated ethylene propylene) a me PFA (perfluoroalkoxy) ma ke ʻano he insulators i nā mea uila. ʻO kēia ma muli o ko lākou kūpaʻa wela kiʻekiʻe, nā waiwai dielectric maikaʻi, a me ke kūpaʻa kemika. I ka ʻoihana semiconductor, hana pinepine nā mea hana i nā mahana kiʻekiʻe a koi i nā mea paʻa a paʻa.
4. ʻOihana Lewa a me ka Pale Kaua
I nā noi aerospace a me ka pale kaua, pinepine nā kūlana o ke kaiapuni i ʻoi loa, me nā mahana haʻahaʻa loa o ka lewa waho a me ka ʻike ʻia ʻana i ka radiation. Hoʻohana ʻia nā Fluoropolymers i ka hana ʻana i nā kaula, nā ʻūpā, a me nā ʻōnaehana uhi pale e hōʻoia i ka hana hilinaʻi ma lalo o nā kūlana koʻikoʻi.
5. ʻOihana Aerospace
Hoʻohana pū ka ʻoihana aerospace i nā fluoropolymers no nā noi e pili ana i nā ʻokoʻa mahana nui a me ka ʻike ʻana i nā wahie jet a me nā lubricants. Hoʻohana ʻia nā Fluoropolymers i nā uhi pale ma nā ʻāpana mīkini a me nā ʻōnaehana wahie.
6. ʻOihana Lapaʻau
I ke ao lapaʻau, he mea koʻikoʻi ka sterility a me ke kū'ē'ē kemika. Hoʻokō nā Fluoropolymers i kēia mau kūlana a hoʻohana ʻia i ka hana ʻana i nā mea lapaʻau e pono e hana ma lalo o nā kūlana sterile a me ka launa pū ʻana me nā wai o ke kino. No ka laʻana, hoʻohana ʻia ka PTFE i nā catheters a me nā mea hana ʻokiʻoki.
7. ʻOihana Kaʻa
Ma ka ʻāpana kaʻa, hoʻohana ʻia nā fluoropolymers i nā ʻōnaehana wahie a me nā ʻōnaehana hoʻoluʻu, a me nā sila a me nā gaskets i kū i nā kemika like ʻole a me nā mahana koʻikoʻi. Kōkua kēia i ka mālama ʻana i ka hana kaʻa ma lalo o nā kūlana hana like ʻole.
8. ʻOihana Ikehu
Me ka ulu ʻana o ka pono no nā kumu ikehu ʻē aʻe a hoʻomau, ke loaʻa nei nā fluoropolymers i nā noi i ka hana mana o ka lā a me ka thermal. ʻO ko lākou kūpaʻa ʻana i nā mahana kiʻekiʻe a me ka radiation UV e lilo ia i mea kūpono no ka hoʻohana ʻana i nā ʻāpana ʻōnaehana hana mana kūpono a paʻa.
9. ʻOihana Meaʻai a me Mea Inu
I ka ʻoihana meaʻai a me ka mea inu, hoʻohana ʻia nā fluoropolymers i nā lako e pili pono ana me ka meaʻai a me nā mea inu. Hoʻomaopopo lākou ʻaʻole e komo nā mea haumia, me ke kūʻē ʻana i nā kemika hiki ke hoʻohana ʻia i ke kaʻina hana hoʻomaʻemaʻe.
Ka hopena
He mau mea hana nā Fluoropolymers me nā ʻano kūikawā, ʻoi aku hoʻi ma ke ʻano o ke kūʻē ʻana i nā kūlana koʻikoʻi e like me ke kiʻekiʻe o nā mahana, nā kemika huhū, a me nā wahi ʻino. ʻO ke kaʻina hana hana paʻakikī, mai ke koho ʻana o ka monomer a hiki i ka hoʻāʻo ʻana i ka huahana hope loa, e hōʻoiaʻiʻo ana i ke kūpono o nā fluoropolymers no ka hoʻohana ʻana i nā noi koʻikoʻi.
Ke nānā nei i nā noi mai ka ʻoihana kemika a i ka aerospace, a mai nā mea uila a i nā mea lapaʻau, ua maopopo he kuleana koʻikoʻi ko nā fluoropolymers e pāʻani ai ma nā ʻano ʻāpana like ʻole. ʻO ka hana hou mau i ka hana ʻana a me ka hana ʻana o nā fluoropolymers e hāʻawi iā mākou i nā mea hana akamai loa, e hiki ai iā mākou ke hoʻoponopono i nā pilikia nui aʻe i nā wahi koʻikoʻi.
