Zvidhinha zveSilica Mullite: Mhinduro Yekupedzisira Yekushandisa Maindasitiri Anopisa Nekupisa Kwakanyanya

Munyika yemaindasitiri anodziya zvakanyanya, kusarudzwa kwezvinhu zvinoramba kugadzirwa kunoratidza zvakananga kushanda zvakanaka, kuchengetedzeka, uye kudzora mitengo.Zvidhinha zveSilica Mullite(inozivikanwawo seSilica-Mullite Refractory Bricks) yave chinhu chinochinja-chinja, nekuda kwekugadzikana kwayo kwakanyanya pakupisa, simba rayo guru, uye kuramba kwayo ngura zvakanaka. Kunyangwe uri kushandisa simende yekubikira, girazi, kana boiler yeindasitiri, zvidhinha izvi zvinopa mashandiro asina kuenzana kuti mabasa ako arambe achishanda zvakanaka.​

1. Nei Zvidhinha zveSilica Mullite Zvichionekwa: Zvakanakira Zvikuru​

Tisati tatanga kushandisa mashandisirwo azvo, ngatitaurei nezvezvinhu zvikuru zvinoita kuti Silica Mullite Bricks ive yakakosha munzvimbo dzinopisa zvakanyanya:
Kuramba Kupisa Kwepamusoro:Nekuwedzera kwekushisa kwakaderera, vanogona kutsungirira kuchinja kwekushisa nekukurumidza (kubva pakupisa kwakanyanya kusvika pakutonhora) vasina kutsemuka—zvakakosha pakuita zvinhu zvine kutenderera kwekupisa kakawanda.​

Kusimba Kwakanyanya:Dzinochengetedza chimiro chadzo pakupisa kusvika 1750°C (3182°F), zvichiita kuti dzive dzakakodzera maindasitiri ane kupisa kwakanyanya kunogara kwenguva refu.

Simba Rakanaka Remuchina:Kunyangwe kana paine zvinhu zvakawanda zvinorema uye kushushikana nekupisa, zvinoramba kuchinja, zvichideredza kudiwa kwekuchinjwa nguva nenguva uye kusava nekushanda.

Kuramba Kuora & Kukukurwa Kwevhu:Dzinomira zvakasimba kune zvinhu zvine simba zvakaita semarara akanyungudutswa, alkalis, uye magasi ane acidic—anowanikwa mukugadzirwa kwesimende, simbi, uye magirazi.

Kufambisa Kwekupisa Kwakaderera:Inobatsira kuchengetedza kupisa mumaovheni kana mumaovheni, ichivandudza mashandiro esimba uye ichideredza mitengo yemafuta.

2. Mashandisirwo Akakosha: Kwainoshandiswa Zvidhinha zveSilica Mullite Excel​

Zvidhinha zveSilica Mullite zvinogona kushandiswa zvakasiyana-siyana uye zvakagadzirirwa kusangana nezvinodiwa zvakasiyana zvemaindasitiri akasiyana-siyana anodziya zvakanyanya. Heano mashandisirwo azvo anonyanya kushanda:

2.1 Indasitiri yeSimende: Nzvimbo dzeMagetsi eKupisa & Nzvimbo dzeCalcination​

Maitiro ekugadzira simende anoenderana nekupisa kwakanyanya kunogara kuripo—kunyanya mumaovheni anotenderera uye munzvimbo dzinoshandiswa calcium. Zvidhinha zveSilica Mullite ndizvo zvinonyanya kusarudzwa pano nekuti:

Dzinotsungirira kupisa kwakanyanya (1400–1600°C) uye kumanikidzwa kwemagetsi kubva mumakironi anotenderera, uko zvimwe zvidhinha zvinowanzo pwanyika kana kupera nekukurumidza.

Kuramba kwavo kurwisa alkali (kubva ku clinker yesimende) kunodzivirira kuora kwezvidhinha, zvichiita kuti horni yacho irambe ichishandiswa uye kuderedza mari yekugadzirisa.

Nyaya Yekushandisa:Mafekitori makuru esimende pasi rose anoshandisa zvidhinha zveSilica Mullite munzvimbo inopisa uye munzvimbo yekuchinja kwemakiln anotenderera, zvichideredza nguva yekushanda ne30% paavhareji.

2.2 Indasitiri yeGirazi: Kuve nechokwadi chekugadzirwa kwakajeka uye kunogara kwenguva dzose​

Magirazi emoto anoshanda patembiricha inodarika 1600°C, magirazi akanyungudutswa nemagasi anoputika zvichikonzera njodzi huru pazvinhu zvinoramba zvichiramba. Zvidhinha zveSilica Mullite zvinogadzirisa matambudziko aya:

Dzinodzivirira ngura inobva mugirazi rakanyungudutswa uye boron oxides (inowanzo shandiswa mukugadzira magirazi), dzichidzivirira kusvibiswa kunokanganisa kunaka kwegirazi.

Kugadzikana kwavo pakupisa kunovimbisa kupararira kwekupisa kwakafanana, kudzivirira nzvimbo dzinopisa dzinokonzera zvikanganiso zvegirazi (semuenzaniso, mabhuru, ukobvu husina kuenzana).

Yakanakira: Magadzirirwo emvura, makamuri ekuchekerera, nenzvimbo dzekunyungudutsa dzegirazi rinoyangarara, girazi remumagaba, uye magirazi emhando yepamusoro.

2.3 Simbi & Simbi: Kutsungirira Simbi Yakanyungudutswa & Simbi Yakapwanyika​

Mukugadzira simbi, kunyanya mumagetsi emagetsi (EAFs) uye machira ekubikisa, Silica Mullite Bricks inodzivirira michina kubva kusimbi yakanyungudutswa, tsvina, uye magasi anodziya zvakanyanya:

Dzinoshivirira kukweshwa uye kukanganiswa kwesimbi yakanyungudutswa, zvichideredza kukurwa kwezvidhinha uye kuwedzera hupenyu hwejira rechoto.

Kuramba kwavo kusimbi oxide uye ngura yetsvina kunodzivirira kutadza kushanda zvakanaka kwejira remadziro izvo zvinokonzeresa kumisa kugadzirwa kunodhura.

Nzvimbo Yekushandisa: Kuisa madziro emativi eEAF, pasi pemachira ekubikisa, uye midziyo yekunatsiridza yekuwedzera.

2.4 Maboiler emumaindasitiri nemidziyo yekupisa: Kuchengetedza kupisa kwakavimbika​

Zvishandiso zvekupisa marara nemaboiler emaindasitiri (semuenzaniso, ekugadzira magetsi) zvinosangana nekupisa kwakanyanya uye magasi anoparadza eutsi. Silica Mullite Bricks inopa:

Kuchengetedza kupisa kuti bhaira rishande zvakanaka, kuderedza kushandiswa kwemafuta uye kuburitswa kwecarbon.

Kuramba magasi ane acidic (semuenzaniso, SO₂, HCl) kubva mukupiswa kwemarara, kudzivirira kuora kwezvidhinha uye kuona kuti zvinoshanda kwenguva refu.​

Maitiro Ekushandisa: Kuisa magirazi emoto webhoyira, makamuri ekupisa anobvisa simba, uye maoxidizer anodziya.

2.5 Mamwe Masangano Ane Tembiricha Yakanyanya​

Zvidhinha zveSilica Mullite zvinoshandiswawo mu:

Zvitofu zveCeramic:Pakushandisa mataira eceramic, zvinhu zvekuchenesa, uye zvinhu zveceramic zvemhando yepamusoro, uko kudzora tembiricha kwakakosha.

Nzvimbo dzekuchenesa mafuta:Muma "catalytic crackers" nevagadziri vezvinhu, vachidzivirira kupisa kwakanyanya uye ngura yehydrocarbon.

Marabhoritari & Zvoto Zvekutsvagisa:Kune zvidzidzo zvedzidzo nemabasa emaindasitiri, uko kugadzikana pakupisa kwakanyanya kusingakurukurwi.​
