Pehea ka hopena o ka wela i ka hoʻoheheʻe uila o ka lole PTFE kiʻekiʻe

Hoʻohana nui ʻia ka lole wela PTFE ma ke ʻano he insulation uila i ka uea harnessing, nā papa transformer, nā wili kaʻa, a me nā kaapuni kiʻekiʻe. Akā, hoʻololi ka mahana - mai ke anu anuanu a i ka wela loa - hoʻololi i kāna ʻano insulating. Hiki iā ʻoe ke hilinaʻi i ka lole PTFE ma 200 ° C? He aha ka hana ma luna o 260°C?

He nuanced ka pane. Hāʻawi ka molecular structure o PTFE iā ia i ka insulation koʻikoʻi ma waena o ka hapa nui o kāna hana hana, akā ʻoi aku ka nui o 260 ° C e hoʻoulu i ka hoʻohaʻahaʻa ʻole. A ʻoiai e hoʻomaikaʻi ana nā mahana anu i nā waiwai uila, hana lākou i ka haʻalulu.

Ua hoʻāʻo ʻo Aokai PTFE i nā waiwai insulation ma waena o nā wela wela. Hoʻokaʻawale kēia ʻatikala i ka hana i ʻekolu mau pae: ka hana maʻamau (-180 ° C a 260 ° C), ke kiʻekiʻe kiʻekiʻe (> 260 ° C), a me ka mahana haʻahaʻa (<0 ° C), me ka ʻikepili koʻikoʻi e pili ana i ka resistivity, ka ikaika dielectric, a me nā hopena kūpono.

Ka Hana Hana Maʻamau: -180 ° C a hiki i 260 ° C - Hoʻopili Paʻa Loa

I loko o kēia ākea, mālama ka lole wela kiʻekiʻe o PTFE i ka hoʻokaʻawale uila a paʻa - kahi pōmaikaʻi nui e kākoʻo ana i kāna noi ʻoihana ākea.

1. Volume & Surface Resistivity

Mechanism: E hāʻule haʻahaʻa ka pale ʻana me ka piʻi ʻana o ka mahana no ka mea ʻoi aku ka nui o ka mahana e hoʻoikaika i ka neʻe wela o nā kaulahao molekala PTFE a hoʻolalelale i ka neʻe ʻana o nā mea lawe haumia. Eia nō naʻe, ʻoiai ma 200°C, ʻoi aku ka PTFE ma mua o ka hapa nui o nā plastics ʻenekinia ma ka lumi wela.

E hoʻomaopopo i ke kūʻē ʻana o ka ʻili: ʻoi aku ka maʻalahi o ka pale ʻana i ka ʻili. ʻO ka PTFE kokoke i ka non-hygroscopic; e hoʻoheheʻe ʻia ka makū o ka ʻili i nā mahana kiʻekiʻe, e hāʻawi ana i ka hoʻopuʻi ʻana i ka ʻili paʻa ma mua o nā kūlana lumi haʻahaʻa kiʻekiʻe.

2. Ka ikaika dielectric

• E emi ana ke piʻi ka mahana. ʻOi aku ka maʻalahi o ka neʻe ʻana o ka molecular molecular i ka pōʻino o ke kahua uila.

• Mai ka lumi wela a hiki i 200°C, hāʻule ka ikaika dielectric pōkole ma kahi o 20%-40%.

• Eia nō naʻe, ʻo ka lole makamae ma kahi o 0.1 mm mānoanoa ke kūpaʻa mau i kekahi mau kilovolts (a i ʻole ʻumi kilovolts no nā māka mānoanoa) ma 200°C – paʻa ka mana insulation paʻa.

3. Dielectric Constant & Dissipation Factor - Ka liʻiliʻi liʻiliʻi

No ke aha kēia mea nui: ʻO ka ʻōnaehana molekula like ʻole o ka PTFE a me ka polarization ultra-haʻahaʻa e hōʻoiaʻiʻo i ka hoʻouna ʻana i ka hōʻailona paʻa a me ka hana wela haʻahaʻa ma lalo o ka lawelawe kiʻekiʻe a me ka wela wela. Hāʻawi kēia i ka PTFE ma ke ʻano he mea insulating kiʻekiʻe kiʻekiʻe no ka RF a me nā noi microwave.

ʻO Aokai PTFE lole wela kiʻekiʻe e hōʻike ʻia e nā mea kūʻai aku no ka hoʻololi ʻana o ka transformer kiʻekiʻe ma muli o kona kūpaʻa Dk (2.05±0.05) a me ultra-low tanδ (0.0002-0.0005) ma waena o ka -50 ° C a 200 ° C. Hāʻawi mākou i nā hōʻike hoʻāʻo waiwai dielectric ma ke noi.

Kiʻekiʻe Kiʻekiʻe Kiʻekiʻe-Menahana: Ma luna o 260°C – Hoʻohaʻahaʻa ʻole ʻia

Ke ʻoi aku ka nui o ka wela o ka lawelawe ʻana i ka PTFE no ka manawa lōʻihi e hoʻoneʻe ʻia ke kino a me ke kemika - ʻaʻole hiki ke hoʻohuli ʻia ka waiwai.

ʻŌlelo aʻo koʻikoʻi: ʻOiai ke kūpaʻa nei ka lole fiberglass kumu i ka 550-750°C ma mua o ka palupalu, ʻo ka fiberglass i uhi ʻole ʻia e komo koke i ka makū ma hope o ka pau ʻole o ka uhi ʻana o ka PTFE a ʻaʻole hiki ke lawelawe kūʻokoʻa no ka insulation kiʻekiʻe.

Kaulana Haʻahaʻa Haʻahaʻa: Ma lalo o 0 ° C - Hoʻomaikaʻi ʻia ka uila akā ʻo ka mīkini ʻokiʻoki

ʻO ke kī nui: ʻOiai ka hoʻonui ʻia ʻana o ka insulation uila ma nā haʻahaʻa haʻahaʻa, lilo ka ʻili PTFE i palupalu. No nā noi cryogenic (e laʻa, nā laina nitrogen wai, superconducting magnets), e hōʻoia ʻaʻole e hoʻokau ʻia ka lole i ka piko ʻoi a i ʻole ke koʻikoʻi mechanical ma lalo o -79°C. I ka wā i haki ʻia, nalowale ka pono insulation me ka nānā ʻole i nā waiwai uila.

Hōʻuluʻulu manaʻo - Noho i loko o 260 ° C no ka Insulation Pono

I ka hōʻuluʻulu ʻana , i loko o ka mahana hana hoʻomau i ʻōlelo ʻia (≤260 ° C), ke kau nei ka mahana i ka hopena maikaʻi ʻole ma ka PTFE kiʻekiʻe-mehana ka lole uila insulation. Noho ka leo resistivity ma luna o 10⊃1;⊃3; Ω·cm ma 200°C; noho mau ka dielectric ma 2.0-2.1; kumu hoʻoheheʻe ma lalo o 0.001. Hoʻolilo kēia i ka PTFE kekahi o nā mea paʻa paʻa i ka wela wela i loaʻa - ʻoi aku ka waiwai no nā noi alapine kiʻekiʻe kahi e pohō nui ai nā polymers ʻē aʻe.

I ka wā i wela nui ai ma mua o 260°C, hoʻomaka ka hāʻule ʻana o ka insulation mai ka palupalu ʻana o ka mīkini a me ka deformation, a hiki i ka hoʻololi ʻana i ka pau ʻana o ka uila. Ma luna o 400°C, hana ka carbonization i nā ala conductive mau. Ma lalo o 0°C, ho'omaika'i ka waiwai uila, akā hiki i ka ha'iha'i mechanical ke pohō i ka uhi.

Pono ka PTFE kiʻekiʻe-mehana lole me ka hōʻoiaʻiʻo insulation waiwai no kou wela pae? Hoʻolako ʻo Aokai PTFE i ka ʻikepili hoʻāʻo dielectric piha mai -70 ° C a i 260 ° C. E hoʻokaʻaʻike mai iā mākou me kāu mau koi wela, ka volta, a me ka alapine.

Hāʻawi ʻia ka ʻikepili ʻenehana i luna e Jiangsu Aokai New Materials Technology Co., Ltd.

Inā makemake ʻoe i nā kikoʻī ʻenehana hou aʻe, nā hoʻonā noi, a me ka hana maʻamau o nā huahana piha piha e like me ka PTFE kiʻekiʻe-mehana lole, PTFE adhesive tape, PTFE mesh conveyor kāʻei, seamless fusing machine belt, ʻaoʻao hoʻokahi ʻaoʻao i uhi ʻia i ka lole PTFE a me ke kiʻekiʻe-mehana kūpaʻa conveyor & fiberglass lole , e ʻoluʻolu e kelepona mai iā mākou:

• Mr. Guo: +86 18944819998

• Mr. Liu: +86 13705266308

Hoʻopili mākou i ka ʻoihana a me ka kūpaʻa e hoʻopuka i nā hoʻonā ʻenehana hoʻokahi a me ke kākoʻo noʻonoʻo ma hope o ke kūʻai aku.
