Chii chiri lightweight thermal insulation brick uye kushandiswa kwayo chii?

Chii chinonzi lightweight thermal insulation brick? Sezvinoratidzwa nezita racho, zvidhinha zvakapfava zvine thermal insulation function zvinonyanya kushandiswa kuchengetedza kupisa uye kudzivirira kupisa, kuchengetedza simba uye kuderedza kupisa kwesimba tsvina.

1. Zvidhinha zvevhu zvishoma

Ichi chigadzirwa chigadzirwa chisina kuremerwa, chine AL2O3 ye30% -46%, inova chidhinha chekuchengetedza kupisa. Iyo huru yezvigadzirwa ivhu clinker kana light clay clinker uye ivhu repurasitiki rinogadzirwa nenzira inopfuta. Izvo zvigadzirwa zvinosanganiswa nemvura kuita dope repurasitiki kana dhaka, iro rinoburitswa kana kukandwa uye kuomeswa mumhepo ine oxidizing pa1250 ° C-1350 ° C.

2. Zvidhinha zvakakwirira zvealuminium

Iyo inozivikanwawo seyakakwira-alumina yekupisa yekuvharisa zvidhinha, ireru refractory zvinhu zvine alumina yemukati inodarika 48%, inonyanya kuumbwa mullite uye girazi kana corundum. Iyo yakawanda density ndeye 0.4 ~ 1.359 / cm3. Iyo porosity ndeye 66% ~ 73%, uye iyo yekumanikidza simba ndeye 1 ~ 8MPa. Good thermal shock resistance;

Zvidhinha zvisingaremi zvakakwirira-alumina zvinowanzoshandisa high-alumina bauxite clinker, wedzera ivhu shoma, uye ipapo shandisa nzira yemhepo kana furo nzira yekukanda muchimiro cheslurry mushure mekugadzirwa, uye moto pa1300 ~ 1500 ℃. Industrial alumina dzimwe nguva inogona kushandiswa kutsiva chikamu chebauxite clinker.

Inokodzera mucheka wemukati uye kupisa kwekushisa kwevheni, pamwe chete nezvikamu zvisina kusvibiswa uye zvakasvibiswa nezvinhu zvakasimba zvekushisa zvakanyungudutswa. Kana yakanangana nemurazvo, tembiricha yekubata kumeso haifanire kudarika 1350°C.

3. Zvidhinha zvemullite, zvinozivikanwawo sezvidhinha zvisingaremi mullite kana kuti mullite thermal insulation zvidhinha, zvinogadzirwa ne-high-alumina bauxite clinker sechinhu chikuru mbishi, uchishandisa furo kana nzira dzemakemikari kuti dzigadzire porous chimiro, uye zvigadzirwa zvinosanganiswa nemvura It. chidhinha chinodzivirira kupisa chakagadzirwa nevhu repurasitiki kana dhaka, iro rinobudiswa uye rinopisa pakupisa kukuru.

Saizi yakajairwa ye mullite poly light brick is 230 * 114 * 65mm, kazhinji kuwanda kwehuwandu ndeye 0.6-1.2g/cm3, uye tembiricha yekushandisa i1300-1550 madhigirii. Chimiro uye saizi inogona kugadzirwa zvinoenderana nezvinodiwa nevatengi. Maererano nekushanda kwekushisa, JM-23, JM-26, JM-28 inogona kugoverwa mumhando nhatu. Chigadzirwa chacho chinogona kubata murazvo wakananga, uye chine hunhu hwekupisa tembiricha kuramba, huremu huremu, yakaderera thermal conductivity, uye yakakosha kuchengetedza simba.
