Yakakwira alumina kupfeka-inodzivirira
refractory castable

Inoshandiswa zvakanyanya mumhando dzakasiyana-siyana dzekupisa

High alumina kupfeka-resistant castable is amorphous refractory castable ine yakazara aluminiyamu yemukati inodarika 75%, iyo inoumbwa nealumina yakakura aggregate ine Al2O3 yemukati inodarika 75% se granular raw material, yakasanganiswa nehigh alumina poda uye zvinowedzera. .Mushure mekugadzwa kwekutanga kwealumina yakakwirira inokandwa, inochengetedzwa kusvika 28d muyero, uye simba rekumanikidza rinogona kusvika 40 ~ 60MPa.Iyo inoratidzirwa nekunonoka hydration kumhanya, simba rakakwirira uye yakakwirira moto kuramba mune inotevera nhanho.Yakakwira alumina inopfeka-inodzivirira castable ine hunhu hweanti permeability, corrosion resistance inokanganisa kuramba, kupfeka kuramba uye yakanaka mechanic properties Inoshandiswa zvakanyanya kumberi nekumashure maarch, pamusoro pechoto, madziro echoto chemuswe uye zvimwe zvikamu zveutility boilers uye mamwe makini ekupisa. .

Refractory zvinhu zvine zviratidzo zvakasiyana zvinogona kugadzirwa zvinoenderana nezvinodiwa. Fonera 400-188-3352 kuti uwane ruzivo

Kushandiswa kwechigadzirwa

Nyaya dzinoda kutarisirwa

● Waomesa kusanganisa kutanga, wozonyorova kusanganisa nemvura.Wedzera mvura yakakwana yekusanganiswa kwemvura panguva imwe chete.Usawedzera mvura paunoda.

● Nguva yekusanganiswa inoenderana nemamiriro ekusanganiswa uye haifaniri kunge yakaderera pane inodiwa nguva shoma yekusanganiswa.Chete mushure mekunge zvinhu zvese zvasanganiswa zvizere zvinogona kuita zvakajairwa kushandiswa.

● Kana pasina musanganisi kana mamiriro asingabvumirwi, apo kusanganiswa kwemaoko kunodiwa, nguva yekusanganiswa ichawedzerwa kuti ione kuti zvinhu zvakanyatsosanganiswa.

● Ndapota shandisai zvinhu zvakasanganiswa mukati memaminitsi makumi matatu.Mushure memaminitsi makumi matatu, kuita kwezvinhu zvinoshanduka uye hazvigone kushandiswa.Rasa zvasara.

Kushandiswa uye dosage

● Vhura pasuru, dururira zvinhu uye admixtures mumusanganisi, musanganiswa wakaoma uye simbisa kwemaminetsi 1-3 kuti uzvisanganise zvizere.

● Wedzera mvura yakakwana (inenge 10% yemvura yekunwa inokandwa) panguva imwe chete, usawedzera mvura paunoda, kusanganiswa kwemvura kwemaminitsi 3-5, uye sanganisa zvakakwana.

Aya mana anotevera makiyi ekubatanidza anofanirwa kutariswa mukushandiswa kwekukandwa kwerefractory, kureva kusanganisa, kudurura, kurapa uye kubika.

Chero dambudziko mune chero chinongedzo rinogona kutungamira mukuderedzwa kwechigadzirwa kana kutadza kushandisa.

Kusanganisa

Kusanganisa kunokamurwa kuita mechanical mixing uye manual kusanganisa.Parizvino, musanganiswa kana dhaka musanganiswa unoshandiswa muindasitiri kusanganisa zvinhu, uye kusanganisa kwemanyorero hakushandiswe Zvishandiso uye maturusi: kumanikidzwa kana dhaka musanganiswa, mabhaketi, zviyero, vibrators, mafoshoro emidziyo, trolleys, nezvimwe.

Kushandiswa kwemvura yekuvaka kunoenderana nekushandiswa kwemvura kunoratidzwa mune yemhando yekuongorora pepa rebatch yezvigadzirwa, uye inoitwa yakanyatso itwa zvinoenderana nemazinga kuti uwane kuyerwa kwakaringana.

Kusanganisa: Sanganisa omesa kutanga wozonyorova.Isa zvinhu zvakawanda mumusanganisi uye woomesa kwemaminetsi 1-3 mukurongeka kwebhegi hombe kutanga uye ipapo bhegi diki kuti riite zvakasanganiswa.Huremu hwekusanganiswa kwega kwega hunotarwa zvichienderana nemashini uye vhoriyamu yekuvaka;zvinoenderana nehuremu hwezvinhu, mvura inodiwa pakusanganiswa kwega kwega inoyerwa zvinoenderana neyakatsanangurwa mashandisirwo emvura, inowedzerwa kune iyo uniform yakasanganiswa yakaoma yakaoma, uye yakamutswa zvizere.Iyo nguva haisi pasi pe3min, kuitira kuti ive yakakodzera fluidity, uye ipapo zvinhu zvinogona kubudiswa nokuda kwekudira.

Kudira

Pamberi pekudururira zvinhu kuvakwa, zvinodikanwa kutarisa kana zvitsigiso zvakasungwa zvakasimba, uye zvipikiri zvinodzivirira kupisa zvinofanira kuiswa kune zvikamu zvinopfuura 500C.Pamusoro pechibatiso chinofanira kupendwa ne 0. 5-1mm gobvu pendi kana kuputirwa nepurasitiki tepi kuti buffer theexpansion simba pashure kupisa uye kubvisa marara muforoma.

Iyo ichangobva kusanganiswa castable inofanira kudirwa nekukurumidza, kazhinji mukati me20min.Dururira iyo yakasanganiswa yakakandwa mu mold, uye isa vibrator mu vibrator nenguva, uye vibrator inofanira kunge yakafanana.Kana iyo pamusoro peiyo castable yakanyungudika, mabhuru anoburitswa.Kana iyo nzvimbo yakanyungudutswa, tsvimbo inodedera inofambiswa, uye kumhanya kwekufamba kuri 1-2m/min.Pakavhomorwa shamhu inozunguzika, sipidhi inononoka.

Kusimba kusati kwapedzwa mushure mekudururwa, tembiricha yesaiti inofanira kuchengetedzwa pamusoro pe10C(10-30.C).Kana tembiricha yesaiti yakadzikira kupfuura 0'C, kudziya kunoenderana uye matanho ekuchengetedza kupisa anofanirwa kutorwa, zvikasadaro zvinokonzeresa kunonoka uye kutungamira mukuderera kwechigadzirwa.

Maintenance

Zvishandiso zvikuru zvinoshandiswa polyethylene firimu repurasitiki, masaga emasaga, etc. Ambient tembiricha zvinodiwa uye kutonga: Kupora tembiricha yemuviri wekukanda zviri nani pakati pe15-35C Kana tembiricha yakapfuura iyi tembiricha, matanho anowirirana ekupisa kana kutonhora anofanira kutorwa, zvikasadaro. kushanda kwechigadzirwa kuchaderedzwa.

Mushure mekunge iyo yakakandwa yakaomeswa, zvinodikanwa kuti uvhare pakarepo pamusoro pemuviri wekuvaka ne polyethylene epurasitiki firimu, uye woifukidza nesaga remashanga rakanyorova kudzivirira kubuda kwemvura uye kukurudzira simende activation Mushure mekuoma, zvinorambidzwa kurova uye vibrate mukati meimwe. zuva.Maererano nemamiriro ekuoma, inogona kuderedzwa mushure memaawa 24-30 ekuoma.

Mushure mekugadzirisa, inofanirwa kuchengetedzwa kwemazuva maviri sezvinodiwa, uye polyethylene firimu repurasitiki nemasaga akanyorova anofanirwa kuwedzerwa panguva yekuchengeta.Mushure memazuva matatu ekurapa, bvisa firimu repurasitiki uye bhegi remashanga.Bvumira muviri wakaoma kuti uome zvakasikwa mumhepo kwezuva rimwe chete usati wabika.

Kubika

Kubika ndiyo yekupedzisira kiyi chinongedzo mukushandiswa kwezvinokandwa.Sezvo muviri wekukanda wakanyanya kuoma, zvinorambidzwa zvachose kupisa nekukurumidza panguva yekubika, zvikasadaro zvinokonzeresa tsaona inoputika.
