Ceramic fiber magumbeze zvinhu zvakakurumbira zvekudzivirira zvinozivikanwa kune zvakasarudzika zvekupisa zvivakwa. Iwo anoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, anosanganisira aerospace, kugadzirwa kwemagetsi, uye kugadzira, nekuda kwekugona kwavo kukuru. Chimwe chezvinhu zvakakosha izvo zvinoita kuti vabudirire ndechekudzikira kwavo kupisa conductivity.
Thermal conductivity chiyero chekugona kwechinhu kuitisa kupisa. Hwakafanana nehuwandu hwekupisa hunoyerera kuburikidza nechikamu chechikamu chechinhu muchikamu chenguva pane musiyano wetembiricha yeyuniti. Mumashoko akareruka, thermal conductivity inosarudza kuti chinhu chinogona kutamisa sei simba rekupisa.
Ceramic fiber magumbeze ane yakanyanya kuderera yekupisa conductivity, inova inodiwa hunhu insulating application. Iyo yakaderera yekupisa conductivity yemagumbeze aya inonyanya kuverengerwa kune yakasarudzika maumbirwo ekuumbwa kweceramic fibers.
Ceramic fibers inogadzirwa kubva musanganiswa wealumina uye silica zvinhu, izvo zvine hunhu hwakaderera hwekupisa conductivity. Idzi shinda dzakatetepa uye dzakareruka, dzine reshiyo huru, zvichireva kuti kureba kwadzo kwakakura kudarika dhayamita radzo. Ichi chimiro chinobvumira mhepo yakawanda uye voids mukati megumbeze, iyo inoshanda sezvipingamupinyi zvinopisa uye inodzivisa kuendeswa kwekupisa.
Iyo yekupisa conductivity yeceramic fiber gumbeze inogona kusiyana zvichienderana nemhando chaiyo uye kuumbwa kwegumbeze, pamwe nekuwanda kwayo. Kazhinji, kupisa kwemafuta emagumbeze eceramic fiber kubva ku0.035 kusvika 0.08 W/m.·K. Rudzi urwu runoratidza kuti magumbeze eceramic faibha ane hunhu hwakanakisa hwekuvharisa, sezvo aine yakaderera yekupisa yekupisa kana ichienzaniswa nezvimwe zvinojairika zvekudzivirira sefiberglass kana rock wool.
The low thermal conductivity yeceramic fiber magumbezeinopa mabhenefiti akati wandei mumaapplication. Chekutanga, inobatsira kuderedza kupisa kurasikirwa kana kuwana, kuve nechokwadi chekushanda kwesimba mumaindasitiri maitiro uye zvivakwa. Nekudzivirira kutamiswa kwekupisa, magumbeze eceramic fiber anobatsira kuchengetedza nzvimbo yakagadzikana uye inodzorwa inoderedza simba rinodiwa kupisa kana kutonhora nzvimbo.
Pamusoro pezvo, iyo yakaderera yekupisa conductivity yemagumbeze eceramic inobatsira mukupokana kwavo nekupisa kwakanyanya. Magumbeze aya anogona kumira tembiricha inosvika 2300°F (1260°C) vachichengetedza kuvimbika kwavo kwechimiro uye zvivakwa zvekudzivirira. Izvi zvinoita kuti zvive zvakanaka kune zvikumbiro zvinosanganisira nzvimbo dzekupisa zvakanyanya, senge mbiru dzechoto kana honi.
