Lapaʻau ʻili o ka Polytetrafluoroethylene (PTFE)

Ma keʻano he mea hana kumu kumu o ka PTFE kiʻekiʻe-mehana lole, Jiangsu Aokai New Materials e hoʻolauna i ka mālama ʻana o ka polytetrafluoroethylene (PTFE).

Hōʻike ʻo PTFE i ke kūpaʻa kiʻekiʻe a me ka haʻahaʻa haʻahaʻa, ke kū ʻana o ka corrosion kemika, ka mea hoʻohui haʻahaʻa haʻahaʻa a me nā waiwai lubricating. Hoʻohana nui ʻia ia i nā mea uila, nā mīkini, nā mea hana kemika, aerospace, biomedicine a me nā māla ʻē aʻe, e loaʻa ana ka inoa o ka 'King of Plastics' . Eia nō naʻe, ma muli o kona inertness kemika a me ka ikehu haʻahaʻa haʻahaʻa, paʻakikī ʻo PTFE i ka hoʻopaʻa ʻana me nā mea ʻē aʻe, e kaupalena ana i kāna mau noi i kekahi ʻano. No ka hoʻomaikaʻi ʻana i ka pili ʻana ma waena o ka PTFE a me nā mea like ʻole, hoʻohana pinepine ʻia nā ʻano hana e hoʻonui ai i ka hana o ka PTFE. No nā huahana like ʻole, hoʻohana maʻamau ʻo Aokai New Materials i nā ʻano hoʻololi o ka ʻili PTFE.

1. Lapaau Kemimi pulu

ʻO ka lāʻau kemika sodium-naphthalene  kekahi o nā ala kūpono no ka hoʻololi ʻana o ka ʻili PTFE. Me ke kaʻina hana maʻalahi a me ke kumu kūʻai haʻahaʻa, ʻo ia ka mea i koho ʻia i ka hana hana ma Aokai New Materials 'PTFE factory.

Hoʻohana nui ʻia ka lāʻau sodium-naphthalene i kahi hopena etching e hana kemika me ka PTFE, e wehe ana i kekahi mau mea fluorine mai ka ʻili. Ke waiho nei kēia i kahi papa kalapona a hoʻokomo i nā pūʻulu polar e like me nā pūʻulu hydroxyl, nā pūʻulu carbonyl a me nā paʻa unsaturated. Hoʻonui kēia mau pūʻulu polar i ka ikehu ʻili o ka polymer, e hoʻemi i ke kihi pili a hoʻomaikaʻi i ka wettability, pēlā e hoʻohuli ai i ka PTFE mai ka non-bondable i mea paʻa.

2. Ka Hana Hoʻopaʻa Mechanochemical

Ke hoʻokau ʻia nā polymers i nā ikaika o waho (e laʻa, ʻokiʻoki, wili, friction, etc.), haki nā kaulahao macromolecular a hana i nā hopena kemika, me ka mechanodegradation, mechanochemical crosslinking, mechanochemical grafting, block copolymerization and stress-activated polymerization. ʻIke ʻia kēia mau mea he polymer mechanochemical reactions.

I ka hoʻopaʻa ʻana mechanochemical, ʻānai ʻia ka ʻili polymer i uhi ʻia. Ma o ka hana mechanochemical, hana ka polimer i ka mechanodegradation e hana i nā radical free macromolecular, a laila hana i nā mea paʻa covalent me nā molekole adhesive, e hana ana i kahi pilina paʻa ikaika a hoʻomaikaʻi nui i ka ikaika paʻa o ka hui.

3. Kiekie-Menahana hehee

ʻO ke kumu kumu o ka hoʻololi ʻana i nā ʻili PTFE ma o ka hoʻoheheʻe ʻana i ka wela kiʻekiʻe: ma nā wela kiʻekiʻe, ua hoʻololi ʻia ka morphology crystalline o ka ʻili PTFE, a ua hoʻokomo ʻia nā mea hoʻopaʻa maʻalahi e like me SiO₂ a me ka pauka Al. Ma hope o ka hoʻoluʻu ʻana, hana ʻia kahi papa i hoʻololi ʻia me nā mea paʻa paʻa ma ka ʻili PTFE. No ka mea, ua komo nā molekala o nā mea paʻa i loko o ka papa mole o ka PTFE, ʻo ka haʻihaʻi ʻana i ka paʻa e pono ai ka luku intermolecular, ka hopena i ka ikaika hoʻopaʻa kiʻekiʻe.

4. Keʻano o ka hoʻoheheʻe ʻana

Hoʻokomo ʻia ʻo PTFE i loko o nā monomers polymerizable reactive e like me styrene, fumaric acid, methacrylates a me nā mea ʻē aʻe, a laila hoʻomālamalama ʻia me Co-60 . Hoʻomaka kēia i ka polymerization graft kemika o nā monomers ma luna o ka ʻili PTFE, e hana ana i kahi papa polymer graft i maʻalahi e hoʻopaʻa. ʻO ka grafting hoʻi e hoʻopōʻino i ka ʻili, hoʻonui i ka wahi paʻa a hoʻonui i ka ikaika paʻa.

5. ʻenehana Lapaʻau Plasma

ʻO ka lapaʻau plasma kekahi o nā ʻenehana wikiwiki loa no ka hoʻololi ʻana o ka ʻili PTFE i nā makahiki i hala.

ʻO ke kumu o kēia ʻenehana ʻo ia ka waiho ʻana i ka laʻana i loko o kahi mea lapaʻau plasma i hoʻolaʻa ʻia, kahi i hoʻopaʻa ʻia ai ka ion bombardment a i ʻole implantation e wāwahi i nā paʻa molekala a i ʻole e hoʻolauna i nā pūʻulu hana ma ka ʻili polymer, e hoʻāla ana i ka ʻili e hoʻokō i ka hoʻololi. Hiki ke kinoea inert, kinoea hana kemika a i ʻole nā ​​mea metala. Hiki ke hoʻololi i ka ʻili o ka polymer i ka hoʻopā ʻana me nā kinoea inert.

Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Materials Technology Co., Ltd.

No nā kikoʻī kikoʻī, nā hiʻohiʻona noi a me nā hoʻonā maʻamau o kā mākou huahana piha - me ka PTFE kiʻekiʻe-mehana lole, PTFE kiʻekiʻe-mehana tape, PTFE kiʻekiʻe wela mesh kāʻei, seamless kāʻei no ka mīkini hoʻopaʻa ʻana, hoʻokahi ʻaoʻao PTFE lole, kiʻekiʻe-mehana pale conveyor kāʻei, kiʻekiʻe-mahana kūʻokoʻa - e ʻoluʻolu e hoʻopili iā mākou i ka lole fiber free a ʻoi aku ka maikaʻi.

Ke kākoʻo mau nei mākou i kahi manaʻo lawelawe o ka maikaʻi o ke kumu kūʻai, ka ʻoihana a me ka kūpaʻa, a ua hoʻolaʻa ʻia i ka hāʻawi ʻana iā ʻoe i nā hopena hoʻokahi a me ka lawelawe hoʻolohe!
