Mene ne bulo mai rufin zafi mai nauyi kuma menene amfanin sa?

Menene bulo mai rufin zafi mai nauyi? Kamar yadda sunan ke nunawa, ana amfani da bulogi masu haske tare da aikin rufewa na thermal don adana zafi da kuma hana zafi, adana makamashi da rage sharar makamashin zafi.

1. tubalin yumbu mara nauyi

Wannan samfurin samfuri ne mai ɗaukar nauyi mara nauyi, tare da abun ciki na AL2O3 na 30% -46%, wanda bulo ne mai hana zafi. Babban kayan albarkatun ƙasa sune lãka mai yumbu ko yumbu mai haske da yumbu da yumbu da aka samar ta hanyar ƙonewa. Ana hada albarkatun da ruwa don yin laka ko laka, wanda ake fitar da shi ko jefar da shi kuma a bushe a cikin yanayi mai oxidizing a 1250°C-1350°C.

2. Bulogin alumina masu nauyi masu nauyi

Har ila yau, an san shi da bulo mai rufi na alumina, abu ne mai sauƙi mai sauƙi tare da abun ciki na alumina fiye da 48%, wanda ya ƙunshi mullite da gilashi ko corundum. Girman girma shine 0.4 ~ 1.359/cm3. A porosity ne 66% ~ 73%, da kuma matsawa ƙarfi ne 1 ~ 8MPa. Kyakkyawan juriya na girgiza thermal;

Tubalin alumina masu nauyi masu nauyi gabaɗaya suna amfani da babban alumina bauxite clinker, ƙara ɗan ƙaramin yumbu, sannan a yi amfani da hanyar iska ko hanyar kumfa don jefawa a cikin nau’in slurry bayan an kasa ƙasa, sannan a kunna wuta a 1300 ~ 1500℃. Ana iya amfani da alumina na masana’antu wani lokaci don maye gurbin ɓangaren bauxite clinker.

Ya dace da rufin ciki da rufin rufin zafi na kiln, da kuma sassan da ba su da lalata da kuma zubar da kayan da aka narkar da su da karfi mai zafi. Lokacin da ake hulɗa kai tsaye tare da harshen wuta, zafin fuskar fuskar kada ya wuce 1350 ° C.

3. Mullite tubalin, wanda kuma aka sani da mullite tubalin mara nauyi ko mullite thermal insulation tubalin, ana yin su da babban alumina bauxite clinker a matsayin babban kayan danye, ta hanyar yin amfani da kumfa ko hanyoyin sinadarai don samar da tsari mai laushi, kuma sinadaran suna gauraye da ruwa. bulo ne mai hana zafi da aka yi da yumbu ko laka, wanda ake fitar da shi ana harba shi da zafi mai zafi.

Matsakaicin girman bulo mai haske na mullite shine 230 * 114 * 65mm, yawanci yawancin yawa shine 0.6-1.2g / cm3, kuma zafin amfani shine digiri 1300-1550. Za a iya daidaita siffar da girman bisa ga bukatun abokin ciniki. Dangane da zafin jiki na aiki, JM-23, JM-26, JM-28 za a iya kasu kashi uku. Samfurin na iya tuntuɓar harshen wuta kai tsaye, kuma yana da halaye na juriya na zafin jiki, nauyi mai sauƙi, ƙarancin zafin jiki, da gagarumin tasirin ceton kuzari.
