Chidhinha chekudzivirira chakareruka chembavha dzegirazi chinogona kuiswa muzvikamu zvitanhatu zvinoenderana neayo akasiyana mbishi zvinhu. Anonyanya kushandiswa ndeakareruka silica zvidhinha uye diatomite zvidhinha. Zvidhinha zvehuremu zvekuisa zvidhinha zvine mabhenefiti ekuita kwakanaka kwekupisa kwemafuta, asi kuramba kwavo kumanikidza, kuramba kweslag, uye kupisa kwekushomeka kushomeka, saka havagone kubata zvakananga negirazi rakanyungudutswa kana murazvo.
1. Zvidhinha zvesilika zvakareruka. Yakareruka silica insulation zvidhinha chigadzirwa chinodzivirira chakagadzirwa kubva silica sechinhu chikuru mbishi, ine SiO2 yemukati isingasviki 91%. Huremu hwehuremu hwesilica insulation zvidhinha ndeye 0.9 ~ 1.1g/cm3, uye kupisa kwayo inongova hafu yeiyo yezvakajairwa silica zvidhinha. Iyo ine yakanaka yekupisa kuvhundutsa kuramba, uye kunyorova kwayo kunyorova pasi pemutoro kunogona kusvika 1600 ℃, iyo yakanyanya kukwirira kupfuura iyo yevhu yekuvharisa zvidhinha. Naizvozvo, iyo yakanyanya tembiricha yekushanda ye silica insulation zvidhinha inogona kusvika 1550 ℃. Iyo haina kuderera pakupisa kwakanyanya, uye kunyange ine kuwedzera kudiki. Chidhinha chesilika chechiedza chinowanzo gadzirwa nekristaro Quartzite seyakagadzirwa, uye zvinhu zvinopisa senge coke, anthracite, sawdust, nezvimwe zvinowedzerwa muzvigadzirwa zvekugadzira porous chimiro uye gasi foaming nzira inogonawo kushandiswa kugadzira porous chimiro.
2. Zvidhinha zve Diatomite: Zvichienzaniswa nezvimwe zvidhinha zvisingaremi zvekudzivirira, zvidhinha zve diatomite zvine yakaderera thermal conductivity. Kupisa kwayo kwekushanda kunosiyana nekuchena. Kupisa kwayo kwekushanda kunowanzo kuve pasi pe1100 ℃ nekuti kuderera kwechigadzirwa kwakakura pakupisa kwakanyanya. Izvo zvigadzirwa zve diatomite zvidhinha zvinoda kupiswa patembiricha yepamusoro, uye silicon dioxide inogona kushandurwa kuita quartz. Lime inogonawo kuwedzerwa sebinder uye mineralizer kukurudzira kutendeuka kwequartz panguva yekupisa, iyo inobatsira pakuvandudza kupisa kwechigadzirwa uye kuderedza shrinkage pakupisa kwakanyanya.
Nyaya inotevera ticharamba tichisuma classification yelightweight insulation brickkuvira kwegirazi. Ndapota ramba wakatarisa!
