Pōmaikaʻi

Ke koho ʻana i nā mea insulation a me nā mea refractory me ka hana maikaʻi loa

• ʻO ka mica tape i hōʻeha ʻia e ka lālani keleawe o ke alakaʻi busway e like me JB/T5019~20 "nā huahana mica insulation uila" a me JB/T6488-1~3 "mika tape" maʻamau.Loaʻa i ka mica tape ka maʻalahi a me ke kūpaʻa wela kiʻekiʻe a me nā waiwai dielectric maikaʻi a me nā waiwai mechanical ma lalo o ke kūlana maʻamau: ka ikaika kulou ≥180MPa;ikaika dielectric ≥35kV / mm;ka hoʻopaʻa ʻana o ka leo >1010Ω-m.Ke piʻi ka mahana i 600 ℃, loaʻa i ka mica tape ke kiʻekiʻe o ka insulation performance insulation resistance >10MΩmm2.
• Wahi a ka palena pale ahi ʻokoʻa o ke ala kaʻa refractory, ʻokoʻa nā ana i lawe ʻia e ka papa insulation wela.Inā pono ke holo kaʻa kaʻa no ka manawa lōʻihi me ka uila, ua hoʻokaʻawale pololei ʻia ka papa insulation wela me ka ea i ʻole e hoʻopilikia i ka hoʻokuʻu ʻana o ka wela i ka wā e hana ai ke ala kaʻa, a i ka wā ʻaʻole i hoʻoikaika mau ʻia ke ala kaʻa no ka hoʻohana ʻana i ka mana pilikia. ʻO ka mea wale nō, ʻoi aku ka kiʻekiʻe o kona palena pale wela a pono e hoʻopiha ʻia ka ʻaoʻao insulation wela me ka hulu silica, ʻo ka mea huluhulu silica i koho ʻia no kēia kaʻaahi refractory conforms me GB3003 "common aluminosilicate refractory fiber mot", kona AL2O3 + SiO2 maʻiʻo hiki i 96% , ʻo 1050 ℃ ka mahana hoʻohana mau, ^ hiki i ka mahana hoʻohana kiʻekiʻe i 1250 ℃.
• Ke hoʻomaka ke ahi i loko o 3 ~ 5 mau minuke, hoʻomaka ka uhi a hoʻonui, e hana ana i kahi papa insulation wela, a piʻi wikiwiki ka conductivity thermal, e hoʻemi pono i ka hoʻoili wela.ʻO nā mea kikoʻī hana āpau o ka uhi ʻana i hoʻohana ʻia i kēia kaʻaahi refractory e like me ka pae aupuni GB14907-94.
• I mea e hoʻokō ai i nā koi refractory, ua hana ʻia ka poloka hoʻokaʻawale ʻana a me ka poloka hoʻokaʻawale hui ʻana i nā mea seramika kūpaʻa kiʻekiʻe, nona ka ʻike Al2O3 ʻoi aku ma mua o 95% a loaʻa iā ia nā mea dielectric a me nā ʻano mechanical ma lalo o nā kūlana maʻamau: ikaika dielectric. ≥13kV/mm ka nui resistivity>20MΩ-cm ikaika flexural ≥250MPa.ʻOi aku ka maikaʻi o ka ceramic i ke kūpaʻa wela, a ʻo ke ana ʻana i ka pale insulation he> 10MΩ ke piʻi ka mahana i 900 ° C.Ma muli o ka paʻa maikaʻi o ka ceramic, ʻaʻohe pilikia kahiko o ka mea insulation, no laila e hoʻolōʻihi i ke ola lawelawe o ke ala kaʻa.
• Nā huahana pili kaiapuni: Inā he ahi, ʻaʻohe kinoea ʻawaʻawa e hoʻokuʻu ʻia mai ke ala kaʻa, ʻaʻole hoʻi i hoʻokumu ʻia ka lua ahi, ʻo ia ka hanauna hou o nā huahana uila pili kaiapuni.
• Uea maʻalahi: Ua hoʻonohonoho pono ʻia ke kikowaena busway plug, a maʻalahi ke huki ʻana i ka lālā o kēia manawa.Hiki ke hoʻokomo ʻia kēlā me kēia pākuʻi i loko o nā pahu plug mana like ʻole, a ua hana pū ʻia ke kiaʻi pahu pahu pahu me nā mea seramika kūpaʻa kiʻekiʻe e hōʻoia i ka hiki ke huki ʻia ka mana i ke ahi.
• NHCCX series refractory busway ua holo maikaʻi i ke ʻano hōʻike o National Electric Control Equipment Quality Supervision, Inspection and Testing Center a me ka refractory test o National Chemical Building Material Testing Center, a me kāna hana uila, hana mechanical a me ka hana refractory aia ma ka home ^ pae e like me ka hookolokolo ana.
