Lepa Hoʻopaʻa Graphite i hoʻopaʻa ʻia

1. Hoʻonohonoho ʻana i nā huahana kumu

Hana ʻia ʻo Corrugated Graphite Sealing Tape mai ka 99.5% kiʻekiʻe -purity flake graphite ma ke ʻano he substrate, i hui pū ʻia me ka wela-elastic adhesive (ʻoi loa ka pale wela o 800 degere), a hana ʻia ma o ka ʻikepili nui -optimized "precision corrugated forming"} ʻO kāna hana koʻikoʻi ka hāʻawi ʻana i kahi "sealing hilinaʻi + hoʻokomo maʻalahi + ola lōʻihi" no nā hiʻohiʻona ʻoihana maʻamau (pipe, valves, reactors) mai ka waena -haʻahaʻa a hiki i ka waena -kiʻekiʻe (-200 degere ~800 degere). Hoʻopuka ʻo ia i nā wahi ʻeha o ka hopena carcinogenic o nā gasket asbestos kuʻuna, ʻaʻole lawa ke kūpaʻa wela o nā gaskets rubber (prone i ka ʻelemakule ma nā mahana ＞250 degere), a me ka hiki ʻole o ka hoʻololi ʻana i nā gaskets graphite maʻamau. Hoʻonohonoho ʻia ma waena o nā huahana TOP 4 wikiwiki loa e ulu nei i ka mākeke mea hoʻopaʻa paʻa honua ma 2025 (19.3% ka nui o ka ulu ʻana o ka makahiki, me ka petrochemical / wai mālama / nā noi mīkini maʻamau no 76%; ʻIkepili: Global Industrial Sealing Materials Market Report 2025).

3. Core hiʻona

Hiki ke hoʻololi a me ke kūpaʻa hana: Ma hope o 1,800 hola o "-200 degere ~800 degere " ho'āʻo wela, ʻo ka hoʻemi ʻana o ka hana hoʻopaʻa ʻana ma lalo o a i ʻole like me 3.8% - palua o ka paʻa o nā lipine hoʻopaʻa graphite maʻamau (he 12% ka attenuation hana ma luna o 600 degere). ʻAʻohe palupalu a pohā paha ma nā wela haʻahaʻa (10 ʻāpana ma -200 degere me ka haki ʻole) a ʻaʻohe carbonization ma waena-wela kiʻekiʻe, kūpono ia no nā hiʻohiʻona e like me nā paipu ma nā ʻāpana ʻākau hauʻoli (-40 degere ), nā mea hana sterilization meaʻai (150 degere ), a me ka mahana wela rechemical (60 degere). Hoʻemi ʻia ka nui o ka hana ʻole ʻana o nā mea kūʻai aku ma lalo o 85%.

Kiʻekiʻe -Efficaling Sealing & Leakage: ʻO ka "arc-like corrugated structure" (ke kiʻekiʻe corrugation: 0.3-2.5mm, customizable) hoʻonui i ka ʻāpana pili o ka ʻili hoʻopaʻa ʻana ma 45%. Ma hope o 1,000 medium-high pressure sealing tests (kiʻekiʻe kiʻekiʻe o ke kaomi o 18MPa), ʻo ka leakage rate he emi ma mua a i ʻole like me 8×10⁻⁷ Pa·m³/s, ʻoi loa aku ma mua o ka Chinese National Standard GB/T 4622.3-2021 no ka leakage sealing maʻamau me (· Liʻiliʻi ma mua o ⁻1⁷. ʻO ka helu kūpono o ka hoʻopaʻa ʻana i ka flange no nā pipeline petrochemical a hiki i 99.4%.

Paʻa ʻino a me ka hoʻohālikelike ʻana i ke kino: Ma hope o 960 mau hola o ka ho'āʻo ʻana i ka hoʻāʻo ʻana (ʻākia-base solutions me ka pH 2-13, nā mea hoʻoheheʻe kūlohelohe e like me ka acetone/ethylene glycol), ʻoi aku ka liʻiliʻi o ka pohō nui ma mua o 1.8%, me ka ʻole o ka pehu a me ka delamination. He kūpono no ka hoʻopaʻa ʻana i ka chlorine -loaʻa nā pipeline wai ʻino i loko o ka ʻoihana mālama wai (ʻoi aku ka pale ʻana o ka chlorine) a me ka media acid-base nāwaliwali i ka ʻoihana kemika, ua hoʻonui ʻia kona ola lawelawe i 2-3 mau makahiki, ke hoʻohālikelike ʻia me nā gaskets (i loaʻa ka pōʻai kūʻē corrosion o 3 mahina).

Hiki ke hoʻololi kiʻekiʻe a me ka hana maʻalahi: Mai ka 0.2{1}}6mm ka mānoanoa (hiki ke ho'ohana 'ia), me ka ma'alahi o ka wela o ka lumi e hiki ai i 300 mau pō'ai piko me nā māwae. E mālama mau ana ia i kekahi elasticity ma 800 degere (compression rebound rate ʻoi aʻe ma mua a i ʻole like me 85%). Ma o ka hoʻāʻo ʻoki ʻana o CNC, ʻoi aku ka liʻiliʻi o ka palahalaha ma hope o ka ʻoki ʻana i nā nui like ʻole (ka laulā kiʻekiʻe o 1,500mm) a me nā ili hoʻopaʻa like ʻole (e laʻa, elliptical flanges) ʻoi aʻe ma mua o 0.1mm. He kūpono ia me ka ʻoi aku o 96% o nā wahi hoʻopaʻa ʻenehana maʻamau (flanges, valves, pumps), a ʻo ka hoʻonohonoho pono ʻana he 55% kiʻekiʻe ma mua o nā gaskets sealing kuʻuna.

 

 

4. Nā noi kumu

Kahua Petrochemical(35% proportion, the large application scenario): Corrugated Graphite Sealing Tape hoʻohana ʻia no ka sila ʻana i ka ʻaila maʻemaʻe e hoʻouna ana i nā pipili paipu (-20 degere ~80 degere) a me -mehana wela o nā ʻāpana hoʻoheheʻe catalytic (300 degere ~500 degere). Wahi a ka ʻikepili hoʻāʻo mai PetroChina Lanzhou Petrochemical, hiki iā ia ke hōʻemi i ka nui o ka leakage pipeline mai 6.1% a i 0.4%, a ʻoki i ke kumukūʻai hoʻopaʻa hoʻopaʻa hoʻopaʻa makahiki o hoʻokahi ʻāpana e 380,000 RMB. He kūpono no ka sulfur-containing medium pipelines (hydrogen sulfide corrosion resistance), kona hoʻopaʻa paʻa ʻana e hoʻokō i nā koi o ka hana mau.

Kahua Hana Wai(22% proportion): Hoʻohana ʻia e hoʻopaʻa ʻia no nā pamu centrifugal i nā mea kanu hoʻomaʻemaʻe wai (ka wela lumi, chlorine -wai wai ʻino) a me nā flanges pipeline i nā hana wai (-5 degere ~40 degere). Hoʻonui ʻia kona ola lawelawe i 2.5 mau makahiki, i hoʻohālikelike ʻia me nā gaskets rubber (prone to corrosion and aging by chlorine), a ua hoʻolōʻihi ʻia ka awelika o ka hoʻololi ʻana i nā mea hana wai mai 2 mahina a 18 mahina. Hoʻokō ia me GB/T 17219-1998 Safety Standard no ka lawe ʻana i ka wai inu a me nā lako hāʻawi, me ka ʻole o nā mea ʻino i hoʻokahe ʻia.

Kahua Mekini Nui(28% proportion): Hoʻohana ʻia no ka hoʻopaʻa ʻana i nā valves compressor (150 degere ~ 300 degere), paʻi ʻana i nā mea wili wili (kahi lumi lumi), a me nā bearings mīkini lole (50 degere ~ 120 degere). Hoʻoponopono ia i ka pilikia o nā gaskets kuʻuna i hiki ke ʻaʻahu a koi i nā pani pinepine no ka hoʻololi ʻana, e hōʻemi ana i ka nui o ka hemahema o nā lako mīkini maʻamau e 42%. ʻOi aku ka maikaʻi o ka hoʻopili ʻana ma mua o nā kinoea metala no nā ili hoʻopaʻa paʻa ʻole (e laʻa, -pili hoʻopāpā kiʻekiʻe kiʻekiʻe).

Meaʻai & Laʻau Laʻau(15% proportion): Hoʻohana ʻia no ka hoʻopaʻa ʻana i nā flanges o nā pahu sterilization meaʻai (121 degere, ka moku mahu) a me nā pipeline o nā lāʻau maloʻo maloʻo (-50 degere ~ 80 degere). Hoʻopili ia me ka FDA 21 CFR Māhele 177.2600 no nā mea pili meaʻai, me ka ʻala ʻole a i ʻole ka ua haumia i nā wela kiʻekiʻe, e hōʻoiaʻiʻo ana i ka maʻemaʻe a me ka palekana o ka meaʻai a me ka lāʻau lapaʻau. Wahi a nā ho'āʻo a Mengniu Dairy, ua hoʻokō nā hoʻokolohua neʻe a pau o nā gaskets i nā kūlana, e hoʻokō i nā koi o ka hana ʻana i ka meaʻai.

Nā huahana pale: ʻO ka lipine hoʻopaʻa ʻia ʻo Corrugated Graphite Sealing, nā mea hana ʻo China Corrugated Graphite Sealing Tape
