Kiʻekiʻe Mahana Kūʻē Graphite Corrugated Tape

1. Hoʻonohonoho ʻana i nā huahana kumu

Kiʻekiʻe Mahana Kūʻē Graphite Corrugated Tapeʻo iahana ʻia mai ka 99.9% kiʻekiʻe-maʻemaʻe i hoʻonui ʻia i ka graphite flake ma ke ʻano he pani,a ʻo iahui pū ʻia me ka mea hoʻopili -kiʻekiʻe ma muli o ka wela -pilikia (me ka palena wela loa o 1200 degere ). Hana ʻia ma o ka ʻikepili nui -kaʻina "multi-pass corrugated forming + gradient curing", hāʻawi ia i kahi "zero-leakage sealing + high-efficiency thermal conductivity" solution no 1000 degere -class extreme high-temperature ({12}}high temperature. reactors, hydrogen ikehu lako, aerospace parts). Hoʻoponopono ia i nā wahi ʻeha o nā lipine graphite kuʻuna (kūʻai wela ʻAʻole i like a i ʻole 600 degere) e loaʻa ana i ka carbonization wela kiʻekiʻe, a me nā sila metala e hiki ke hoʻonui i ka wela. Hoʻonoho ʻia ma waena o ka TOP 3 wikiwiki loa -huahana e ulu ana i ka 2025 kiʻekiʻe-makeke ʻenehana ʻenehana (25.8% ka nui o ka ulu makahiki, me ka ikehu hou hydrogen energy/petrochemical kiʻekiʻe-noi ka 71%; Kumu ʻikepili: Global High-Temperature White Paper Sealing Materials).

Ka -Ui Kūleʻa Kiʻekiʻe a me ka Paʻa Hana Hana: Ma hope o 2000 mau hola o 1000 degere ho'āʻo wela mau + 500 pōʻaiapuni o "-200 degere ~1000 degere " hoʻāʻo haʻalulu wela, ʻoi aku ka liʻiliʻi o ka hana sealing attenuation ma mua o 2.5% a i ʻole like me 2.5%, a ʻoi aku ka nui o ka conductivity thermal longitudinal ma mua a i like paha me 500 W/m · mau manawa kiʻekiʻe ma mua o 500 W/m·K manawa kiʻekiʻe kiʻekiʻe-ka wela graphite lipine (he 15% ka attenuation hana ma 600 degere ). ʻAʻole hiki ke hoʻoheheʻe ʻia a i ʻole ka carbonization i nā wela kiʻekiʻe, no laila kūpono ia no nā hiʻohiʻona koʻikoʻi e like me nā kapuahi kilikaki photovoltaic (1000 degere) a me nā kapuahi hauhā hydrogen (900 degere). Hoʻemi ʻia ka helu hemahema o nā mea kūʻai aku ma lalo o nā kūlana hana kiʻekiʻe e 89%.

Kiʻekiʻe -Hoʻopaʻa Sila ʻana ma lalo o nā Mahana Kiʻekiʻe Loa: ʻO ka "trapezoidal corrugated structure" (ke kiʻekiʻe corrugation: 0.8-3mm, customizable) e hōʻoia i ka hoʻopaʻa ʻana o ka nui o ka nui ma mua o a i ʻole like me 95% ma nā wela kiʻekiʻe. Ma hope o 1200 manawa o 1000 degere /15MPa kiʻekiʻe - hoʻāʻo hoʻopaʻa hoʻopaʻa ʻana, ʻoi aku ka liʻiliʻi o ka leakage ma mua o a i ʻole like me 5×10⁻⁷ Pa·m³/s, ʻoi loa aku ma mua o ka Chinese National Standard GB/T 4622.3-2021 no ka haʻahaʻa haʻahaʻa a i ʻole ka haʻahaʻa haʻahaʻa. 1×10⁻⁵ Pa·m³/s). ʻO ka helu kūpono o ka hoʻopaʻa ʻana i ka reactor wela kiʻekiʻe i ka ʻoihana petrochemical a hiki i 99.6%.

Kiʻekiʻe -Mahana Kūʻai Kūʻē a me nā Kemika Inertness: Ma hope o 1000 mau hola o ka hoʻāʻo ʻana i ka hoʻāʻo ʻana i ka waika concentrated 800 degere (98% H₂SO₄) / alkali ikaika (50% NaOH), ʻoi aku ka liʻiliʻi o ka nui o ka pohō ma mua o 1.2%, me ka ʻole o ka māhā a me ka pehu. ʻAʻohe hopena kemika i ka wā e pili ana me ka hoʻohaʻahaʻa kinoea e like me ka hydrogen a me carbon monoxide i nā wela kiʻekiʻe, e kūpono ai i nā mea hana ikehu hydrogen (e pale aku i ka hydrogen embrittlement) a me nā pipeline kiʻekiʻe -anahu kiʻekiʻe (kū kūʻē i ka corrosion tar). Hoʻonui ʻia kona ola lawelawe a ʻoi aku ma mua o 5 mau makahiki, ke hoʻohālikelike ʻia me nā sila metala (ʻo ia ka -kiʻekiʻe o ka pōʻaiapili pōʻino ʻino o 3 mahina).

Kiʻekiʻe -Mechanical Pono a me ka hana: Mai ka 0.5{3}}8mm ka mānoanoa (hiki ke hoʻololi ʻia), a mālama ʻo ia i 180 degere pelupi me ka haki ʻole i ka 800 degere (ka lumi -malili hiki ke hoʻololi i ka wela ma mua a i ʻole like me 200 mau pōʻai piko me ka ʻole o nā māwae). Ma o ka hoʻāʻo ʻana i ka ʻoki ʻana i ka laser CNC, ʻoi aku ka liʻiliʻi o ka ʻaoʻao ma hope o ka ʻoki ʻana i nā ʻāpana like ʻole (ka laulā kiʻekiʻe o 1200mm) ʻoi aku ka liʻiliʻi ma mua o 0.08mm. He kūpono ia me ka 98% o ka -mea wela kiʻekiʻe e hoʻopaʻa ai i nā ʻili (e laʻa, nā flanges reactor irregular, hydrogen storage tank interfaces), a he 60% ʻoi aku ka maikaʻi o ka hoʻokomo ʻana ma mua o ko nā kinoea hoʻopaʻa hoʻopaʻa wela wela.
