Introduction to Jiangsu PTFE High-Temperature Fabric Manufacturers: He aha nā hopena i loaʻa i ka Gamma-Ray Irradiation i ke ʻano a me nā waiwai o PTFE?

Nā hoʻololi i ka hoʻolālā kemika: ʻokiʻoki i ke kaulahao nui a me ka oxidation

1. ʻO ka ʻokiʻoki ʻana i ke kaulahao nui a me ka emi ʻana o ke kaumaha o ka molekole

Na nā kukui Gamma e uhaki pono i nā kaulahao nui CC a me nā kaulahao ʻaoʻao CF o PTFE. ʻO kāna hua kemika radiation (G-value) hiki i ka 3.0-3.5. Hiki ke ʻoki ʻia ke kaulahao nui ma nā haʻahaʻa haʻahaʻa loa, e alakaʻi ana i kahi hāʻule nui o ke kaumaha molekala. Mea hana o ʻO ka lole wela kiʻekiʻe PTFE ma Jiangsu e noʻonoʻo i kēia ke kumu kumu o ka hōʻino ʻana o ka hana.

2. Nā Hana Hoʻopalekana Kūʻokoʻa a me ka Oxidation

Ma lalo o nā kūlana oxygen ʻole, nā radical manuahi i hana ʻia e ke kaulahao scission e hana hou a i ʻole disproportionation e hana i nā perfluoroalkanes pōkole. I loko o kahi kaiapuni aerobic, hui koke nā radical manuahi me ka oxygen e hana i nā radical peroxy, e hoʻoulu ai i nā hopena kaulahao e uhaʻi hou ai i nā kaulahao molekala a hoʻokomo i nā hui hope e like me acyl fluorides a me nā waikawa carboxylic. I ka ʻike ʻana i ka makū, hoʻoheheʻe ʻia nā acyl fluoride i loko o nā ʻakika carboxylic a hoʻokuʻu i ka hydrogen fluoride (HF), e hoʻohaʻahaʻa loa i ka mea.

Nā Hoʻololi i ka Hoʻolālā Moku'āina Condensed: Crystallinity and Morphology

1. Piʻi mua ka Crystallinity a laila hāʻule

Ma nā haʻahaʻa haʻahaʻa (maʻamau ma lalo o 50 kGy), hoʻopuka ka ʻoki kaulahao nui i nā ʻāpana kaulahao pōkole me ka hoʻoikaika ʻana i ka neʻe ʻana, e hoʻonohonoho maʻalahi i ke ʻano i kauoha ʻia a hoʻonui ʻia ka crystallinity. Ke piʻi aʻe ka nui o ka radiation, nui nā hemahema a me nā huahana hoʻohaʻahaʻa e hoʻopau i nā hale aniani, a emi iho ka crystallinity.

2. Ka luku ʻia ʻana o ka Lamellar Crystal Structure

E like me ka nānā ʻana e nā mea hana PTFE lole wela kiʻekiʻe ma Jiangsu: Hōʻike nā hopena WAXS/SAXS e hoʻohaʻahaʻa ka irradiation i nā kristal lamellar lōʻihi o PTFE i loko o nā crystallites liʻiliʻi. Nalo ka hale kauoha lōʻihi, hele pū ʻia me nā lamellae aniani ʻoi aku ka lahilahi a me nā hemahema i hoʻonui ʻia.

Nā Hoʻololi Waiwai Macroscopic: Hoʻopau piha

1. Nā Pono Mechanical

Hoʻomaka ka emi ʻana o ka elongation i ka wā hoʻomaha ma ka 0.1 kGy wale nō i ka lewa, a nalowale ma luna o 90% ma kahi o 1 kGy. Nalo loa ka mea i ka paʻakikī a lilo i ʻoʻoleʻa a palupalu. Hiki ke piʻi iki ka ikaika tensile i ka pae mua ma muli o ka piʻi ʻana o ka crystallinity, a ma hope o ka emi wikiwiki ʻana; piʻi ka elastic modulus, ʻoiai ke kūʻē ʻana i ka ʻaʻahu a me ke kū ʻana i ka luhi.

2. Na waiwai wela

ʻO nā lamellae aniani i hoʻoheheʻe ʻia a me nā hemahema o ke kūkulu ʻana e hoʻemi mālie i ka helu heheʻe mai 327 °C a i lalo o 310 °C, me ka emi ʻana o ka mahana crystallization. ʻO nā pūʻulu hope paʻa ʻole ma nā kaulahao polymer e hoʻohaʻahaʻa loa i ka wela o ka hoʻoheheʻe wela mua a hoʻopilikia i ka paʻa wela.

3. Na Waiwai Uila a me ke Ana

ʻO nā pūʻulu polar (e laʻa, nā pūʻulu carbonyl) i hoʻokomo ʻia e ka hoʻohaʻahaʻa ʻana e hoʻonui iki i ka pau ʻana o ka dielectric mau a me ka nalowale dielectric. Hoʻololi ka ʻili o ka mea mai ke keʻokeʻo a i ka hina a ʻeleʻele hope loa, i hele pū ʻia me ka nalowale nui o ka ʻōlinolino a me ka embrittlement.

Nā mea hoʻoikaika nui

1. Kaiapuni Iradiation

ʻOi aku ka koʻikoʻi o ka pōʻino o ka ea ma mua o ka lewa a i ʻole ka lewa. Hoʻokomo ʻo Oxygen i nā hopena kaulahao self-oxidation ma hope o ka ʻoki ʻana i ke kaulahao, hoʻonui i ka maikaʻi o ka hoʻohaʻahaʻa ʻana a me ka hana ʻana i nā pūʻulu hopena pōʻino. ʻO kēia ka palena mua e kaupalena ana i nā noi PTFE ma lalo o ka hoʻolaha ʻana i ka radiation.

2. Ka huina nui a me ka helu helu

Hoʻoholo ʻia ka nui o ka pōʻino holoʻokoʻa. Ma lalo o nā kūlana aerobic, ʻoi aku ka maikaʻi o ka hopena haʻahaʻa haʻahaʻa ma mua o ka nui o ka nui o ka irradiation. Loaʻa ka manawa kūpono o ka oxygen e hoʻomau i ka hoʻoheheʻe ʻana i loko o ka mea i loko, e hana ana i nā papa hoʻohaʻahaʻa oxidative hohonu a ʻoi aku ka maikaʻi a me ka hōʻino maikaʻi ʻana, e wikiwiki ana i ka nalowale o nā waiwai mechanical. No laila, manaʻo nā mea hana o ka PTFE kiʻekiʻe-mehana lole ma Jiangsu i ka PTFE maʻamau ʻaʻole kūpono i nā kaiapuni radiation.

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

Inā makemake ʻoe e aʻo i nā kikoʻī kikoʻī hou aku, nā hiʻohiʻona noiʻi a me nā hoʻonā i hoʻoponopono ʻia no kā mākou huahana piha, me ka PTFE kiʻekiʻe-mehana lole, PTFE kiʻekiʻe-mehana adhesive tape, PTFE mesh conveyor kāʻei, seamless fusing mīkini kāʻei, hoʻokahi ʻaoʻao PTFE lole, kiʻekiʻe wela kūʻokoʻa conveyor kāʻei a me ka wela kiʻekiʻe, e ʻoluʻolu e kelepona iā mākou ma o ka fiberglass.
