Ma keʻano he mea hanaʻoihana o PTFE adhesive tape a me nā huahana insulation pili, Jiangsu Aokai New Materials Technology Co., Ltd. kaʻana like i ka ʻike nui. ʻOiai ua waiwai ʻia ka lipine kiʻekiʻe o ka PTFE no kāna mau waiwai dielectric maikaʻi loa a me ke kūpaʻa wela, ʻo nā kūlana hana kiʻekiʻe kiʻekiʻe a me nā kūlana hana kiʻekiʻe e hoʻolauna i nā pilikia he nui.
ʻO ka hoʻomaopopo ʻana i kēia mau pilikia - me ka ʻelemakule wela kiʻekiʻe, ka haki ʻana o ka uila, ka nalowale o ke alapine kiʻekiʻe, a me nā mea kūlohelohe - pono no ka hoʻolālā ʻana o ka ʻōnaehana hilinaʻi.
Pilikia Ikaika Uila
Kiʻekiʻe-Voltage Breakdown: PTFE tapes i kaupalena dielectric breakdown kū'ē. No ka laʻana, hiki i kahi lipine me ka 0.11mm ka mānoanoa holoʻokoʻa ke loaʻa ka puʻupuʻu haʻihaʻi ma kahi o 6.1kV. ʻAʻole lawa ka mānoanoa a i ʻole nā haumia o loko (pinholes, contaminants) hiki ke hana maʻalahi i ka haʻihaʻi kiʻekiʻe-voltage a me ka hiki ʻole o ka insulation.
Hoʻokuʻu hapa (Corona Discharge): Ma nā kaiapuni kiʻekiʻe-volt, nā mea haumia o ka ʻili (ka lepo, nā ʻaila ʻaila) a me nā ʻāpana ea liʻiliʻi o loko e hana i nā wahi koʻikoʻi o ke kahua uila, e hoʻoulu ai i ka hoʻokuʻu ʻana i ka corona. ʻO ka hoʻokuʻu mau ʻana no ka wā lōʻihi e hoʻopau mālie i ka papa insulating, e alakaʻi ana i ka hāʻule ʻole.
Hoʻohaʻahaʻa ʻia ka Insulation mai nā kumu kūlohelohe:
Humidity: Ke ʻoi aku ka haʻahaʻa haʻahaʻa ma mua o 85%, hiki ke hāʻule nui ka resistivity o ka ʻili o ka PTFE - mai 10⊃1;⁷Ω a i kahi 10⊃1;⊃2;Ω - a hiki ke hoʻemi ʻia ka uila haʻihaʻi e 30% a 50%.
Nā mea hoʻohaumia: ʻO ka lepo a i ʻole ka paʻakai paʻakai ma ka ʻili lipine e hana i nā alahaka conductive, e hana ana i nā ala leakage o kēia manawa.
I nā mea uila uila kiʻekiʻe, ʻaʻole i paʻa ka ikaika dielectric o nā lipine PTFE akā hilinaʻi nui i nā kūlana noi. No nā māka pale corona, hoʻokomo pinepine nā mea hana i nā mea hoʻopihapiha inorganic e like me ka mica a i ʻole nā ʻāpana ceramic i loko o ka matrix PTFE. Hoʻokumu kēia mau mea hoʻopihapiha i nā micro-interfaces he nui e hoʻopuehu i ka manaʻo o ka uku a hoʻopaʻa i ka hana hoʻokuʻu hapa. Ke koho ʻana i ka lipine PTFE no nā motika inverter kiʻekiʻe (e laʻa, 6kV a 10kV papa), pono ia e hoʻohana i ka tape PTFE kūpaʻa i ka corona me ka mānoanoa o ka liʻiliʻi o 0.18mm a hōʻoia i ka hoʻokuʻu ʻana i ka puʻupuʻu inception (PDIV) ma lalo o nā mahana hana maoli, ʻoiai ke emi nei ka PDIV ma 20-30% C ma ke ana wela o ka lumi.
ʻO nā pilikia paʻa wela
ʻO ka ʻelemakule kiʻekiʻe: Hiki i nā lipine PTFE ke hana paʻa i ka mahana mau o 260 ° C. Eia naʻe, ke piʻi ka mahana ma mua o 250°C (ʻoi loa ma kahi o 300°C), hoʻomaka nā kaulahao molekala e decompose. Hoʻemi nui kēia decomposition i ka ikaika dielectric a hana i nā pōʻino insulation.
Thermal-Oxygen Synergistic Effect: ʻO ka hui pū ʻana o ka wela kiʻekiʻe a me ka oxygen e hoʻolalelale i ka ʻelemakule. Ma lalo o nā kūlana wela a me ka haʻahaʻa, hiki ke hoʻonui ʻia ka pōʻino i ka hana ʻana o ka volta e 30% a 50% ke hoʻohālikelike ʻia me ka wela maloʻo wale nō.
Ke hoʻohana ʻia ka lipine PTFE i loko o nā mea hoʻololi i hoʻopaʻa ʻia a i ʻole nā wili transformer kahi i kaupalena ʻia ai ka hāʻawi ʻana o ka oxygen, ʻokoʻa ka ʻano o ka ʻelemakule wela mai nā kūlana ākea. Hōʻike nā haʻawina ʻo ka PTFE ka thermal decomposition rate i loko o ka nitrogen ma kahi o hoʻokahi hapaʻumi o kēlā i ka ea ma ka mahana like. ʻO ia hoʻi, no nā ʻāpana kiʻekiʻe-voltage i hoʻopaʻa ʻia me ka hermetically, hiki i ka tape PTFE ke hoʻokō i ke ola lawelawe ʻoi aku ka lōʻihi ma nā mahana ma luna o 260°C. Eia nō naʻe, i ka wā e hoʻomaka ai ka palaho, ʻo nā huahana e like me ka carbonyl fluoride a me ka perfluoroisobutylene he mea ʻawaʻawa loa a ʻino i nā mea pili metala. No laila, he mea koʻikoʻi e hōʻoia i ka noho ʻana o ka mahana noi ma lalo o ka paepae decomposition - ua ʻōlelo ʻia kahi palena palekana o 30-50 ° C no ka insulation high-voltage koʻikoʻi.
Nā Kūlana Kūlana Kiʻekiʻe
ʻO ka hōʻailona hōʻailona a me ka distortion: ʻO ka dielectric mau (Dk) o ka PTFE maʻamau mai 2.0 a 2.6. Hiki i nā huahana me ka hoʻokaʻawale nui ʻana ma Dk ke hoʻoulu i ka attenuation a me ka distortion o nā hōʻailona kiʻekiʻe i ka wā o ka lawe ʻana - he pilikia koʻikoʻi no nā noi RF a me ka microwave.
Heat Generation Effect: PTFE he haʻahaʻa loa dielectric loss tangent (tan δ), ma lalo o 0.0025. Eia nō naʻe, inā kiʻekiʻe loa ka mea pohō (ma muli o nā haumia a i ʻole ka hana kūpono ʻole), e hana ʻia ka wela nui ma lalo o kahi māla uila kiʻekiʻe. ʻO kēia hopena hoʻomehana ponoʻī e hoʻolalelale i ka ʻelemakule waiwai a hiki ke alakaʻi i ka holo wela.
Mechanical & Environmental Aptability Riskes
Poino Mechanical Stress: ʻO ka hoʻomau ʻana a me ka hoʻopaʻapaʻa i ka wā o ka hoʻokomo ʻana a i ʻole ka hana ʻana ke kumu i nā micro-cracks a me ka abrasion i loko o ka mea, e hōʻino ai i ka hana insulation holoʻokoʻa. Pono e pale ʻia nā piko ʻoi a i ʻole nā kihi.
ʻO ke kino a me ka hoʻoheheʻe ʻana: ʻO nā mea hoʻoheheʻe ikaika e like me nā metala alkali i hoʻoheheʻe ʻia a me nā hydrocarbons chlorinated, a me ka hoʻoheheʻe ʻana i ka ikehu kiʻekiʻe (ma luna o 10⁴ Gy), e hoʻopau i ke ʻano molekala o PTFE a e hōʻemi loa i kona ikaika dielectric.
ʻAʻole Paʻa: Hiki ke hoʻopalupalu a nalo ka hoʻopaʻa ʻana ma lalo o ka mahana wela ke koho ʻole ʻia (e laʻa me ka acrylic-based adhesives, e hoʻoneʻe ai i ka lipine, wehe ʻia, a kolo paha - pilikia loa i nā noi kūlou a haʻalulu paha.
ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa: ʻO ka hapa nui o nā lipine PTFE e nalowale i ka maʻalahi a lilo i mea palupalu ke hāʻule ka mahana ma lalo o -70 ° C. ʻOiai kakaʻikahi i nā noi uila, pili kēia i nā mea hana waho a i ʻole aerospace i ʻike ʻia i ke anuanu.
Ka hopena - ʻO ke koho ʻana i ka Risk-Aware e hōʻoia i ka hilinaʻi
ʻO ka hoʻohana ʻana i ka lipine adhesive PTFE i nā noi kiʻekiʻe-volt a me nā alapine kiʻekiʻe e pono e noʻonoʻo pono i nā kumu pilikia. Ma ka hoʻomaopopo ʻana i nā palena o ka ikaika uila, ke ʻano o ka wela wela, nā waiwai dielectric kiʻekiʻe, a me ka ʻike ʻana i ke kaiapuni, hiki i nā ʻenekini ke koho i ka papa lipine kūpono - a i ʻole ke noi ʻana i nā hoʻonā maʻamau - e pale i ka hāʻule ʻole.
E like me ka PTFE kiʻekiʻe-mehana lipine mea hilinaʻi , Aokai hāʻawi i nā huahana i hoʻopili ʻia no ke koi ʻana i nā noi insulation uila ma waena o ka lole i uhi ʻia ʻo PTFE, ke kāʻei conveyor PTFE, ke kāʻei mesh PTFE, ke kiʻi ʻoniʻoni PTFE, a me ka tape fiberglass PTFE..
Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Materials Technology Co., Ltd.
No nā palena ʻenehana kikoʻī, nā hoʻonā noi, a me nā lawelawe maʻamau no kā mākou huahana holoʻokoʻa me ka PTFE kiʻekiʻe wela lole, PTFE kiʻekiʻe wela tape, PTFE kiʻekiʻe wela mesh kāʻei, seamless fusing mīkini kāʻei, hoʻokahi ʻaoʻao PTFE lole, kiʻekiʻe wela kūpaʻa conveyor kāʻei a me ka wela-pale fiberglass lole , e ʻoluʻolu e kelepona mai iā mākou me ka manuahi:
Hoʻopili mākou i ka manaʻo ʻoihana ʻoihana o ka ʻoihana a me ka kūpaʻa, a ua hoʻolaʻa ʻia i ka hāʻawi ʻana i nā hoʻonā pono hoʻokahi a me nā lawelawe noʻonoʻo no nā mea kūʻai aku a pau.
