Patinosarudza chigadzirwa checeramic fiber, isu zvirokwazvo tichabvunza mugadziri weiyo huru yekuita data yechigadzirwa uye tinzwisise kukosha kwedhata yereferensi mukusarudzwa, asi pamwe mutengi haana kunyatso kujeka pamusoro pezvinoreva kukosha kana zvimwe zvitsva. vatengi havanzwisise zvinorehwa nedata, gara uchitibvunza nezve zvinoreva data.Nhasi 100 tarisa kuti iwe utsanangure zvigadzirwa zveceramic fiber zveiyi ruzivo rudiki, ndinovimba kukubatsira!
1 Musiyano uripo pakati pemafuta ekudzivirira zvinhu uye refractory zvinhu
Kazhinji kutaura, pasi pe1570 ℃ inonzi insulation material;Pamusoro pe1570 ℃ ndeye refractory zvinhu.Chinyakare refractory zvinhu zvinowanzo reva inorema firebrick, inokandwa, nezvimwewo, iyo vhoriyamu density inowanzo 1000-2000kg/m3.
Zvakanakira zveceramic fiber zviri pachena kwazvo, pasi pechiratidziro cheakanakisa kupisa kupisa kwekuita, asi zvakare ine yakanaka kupikisa moto, uye ndeyezvinhu zvakareruka, kuderedza mutoro wechoto, kuderedza zvakanyanya kuiswa kwechinyakare nekuda kwerutsigiro rweanorema. zvinhu zvinopedzwa nenhamba yakawanda yesimbi.
2 kupisa waya shrinkage
Index yekuongorora kupisa kwekudzivirira (sevhisi tembiricha) yeceramic fiber zvigadzirwa.International yakabatana zvinodiwa zveceramic fiber zvigadzirwa pasi peisina-mutoro kudziyisa kune imwe tembiricha, kuchengetedzwa kwekupisa kwemaawa makumi maviri nemana epamusoro tembiricha mutsetse shrinkage inoratidza kupisa kupisa kweceramic fiber.
Iyo tembiricha yekudziya yekudziya waya shrinkage kukosha ≤3% ndiyo inoenderera sevhisi tembiricha yeceramic fiber zvigadzirwa.Panguva iyi tembiricha, amorphous ceramic fibers inopenya uye inokura zvishoma nezvishoma, uye iyo fiber midziyo yakagadzikana uye yakanyungudika.
Heating waya shrinkage kukosha ≤4% bvunzo tembiricha nokuda zvedongo faibha zvigadzirwa kushandisa tembiricha.
3 Thermal conductivity
Thermal conductivity imhando yemidziyo yenyama yemidziyo, inova indekisi yekupisa yekupisa pfuma yeceramic fiber.
Zvinoenderana nechimiro checeramic fiber zvigadzirwa, vhoriyamu density, tembiricha, mhepo yevira, humidity nezvimwe zvinhu.
Ceramic fiber musanganiswa wefiber yakasimba uye mhepo ine porosity ye93%.Mhepo yakawanda ine yakaderera yekupisa conductivity inozadzwa mumapores, uye inoenderera ine network maitiro emamorekuru akasimba inoparadzwa, kuitira kuti iwane yakanakisa adiabatic performance.Uye iyo diki dhayamita yepore, pamwe negwaro rekuyerera kwekushisa nefaibha yakasimba yakakamurwa kuita yakavharwa mamiriro ehuwandu hwema pores, zviri nani kupisa kwekupisa kwekuita kweceramic fiber.
4. Kufurira kwemakemikari
Iyo kemikari yakagadzirwa inosarudza zvakananga kupikisa kwekupisa kwefiber:
(1) Al2O3, SiO2, ZrO2, Cr2O3 uye zvimwe zvinobudirira zvinoriumba ≥99%, yakakwirira tembiricha oxide content, zvakananga inosarudza kuita zvedongo fiber.
(2) Fe2O3, Na2O, K2O, MgO nezvimwe zvisina kuchena zvisingasviki 1%, ndezvetsvina inokuvadza, inotungamira zvakananga mukuipa kweceramic fiber performance.
