Isamente eRefractory kunye nodaka

Inkcazelo emfutshane:

Udaka lwe-refractory, olukwabizwa ngokuba ludaka lomlilo okanye izinto ezidibeneyo (umgubo), ezisetyenziswa njengemveliso yokudibanisa imveliso yezitena, ngokwezinto eziphathekayo zinokwahlulwa zibe ngudongwe, i-aluminium ephezulu, i-silicon kunye ne-magnesium refractory mortar, njl. yenziwe nge-refractory clinker powder kunye nodongwe lweplastiki njenge-binder kunye ne-agent yeplastiki. Amandla ayo kwiqondo lokushisa eliphantsi, kwaye ukubunjwa kwe-ceramic bonding kwiqondo lokushisa eliphezulu kunamandla amakhulu.

Inkcazo

Udaka lweRefractory yimathiriyeli edityanisiweyo esetyenziselwa ukwakha iimveliso ezichasayo ezimile. Yenziwe ngomgubo ochasayo, amanzi okanye isibophelelo solwelo kunye nemixube (efana ne-dispersant plasticizer, stabilizer okanye i-agent yokugcina amanzi). I-slurry efana ne-paste (okanye i-suspension engqingqwa) equlethe i-concentration ephezulu yamasuntswana aqinileyo, eneempawu zolwelo lwe-Bingham. Ubungakanani obuqinileyo / obumanzi bumalunga (70 ~ 75) / (30 ~ 25) kunye nomlinganiselo oqinileyo / we-liquid volume uhluka kunye nobunzima obuthile bepowder refractory, malunga (35 ~ 50) / (65 ~ 50). Ngokuqhelekileyo, isetyenziswe nge-spatula.

Ukuhlelwa

Udaka lwe-refractory, olukwabizwa ngokuba ludaka lomlilo okanye izinto ezidibeneyo (umgubo), ezisetyenziswa njengezinto zokubopha imveliso ye-refractory brickwork, ngokwezinto eziphathekayo zinokwahlulwa zibe ngudongwe, i-aluminium ephezulu, i-silicon kunye ne-magnesium refractory mortar, njl.

Ibizwa ngokuba yi-refractory mortar eqhelekileyo eyenziwe ngomgubo we-refractory clinker kunye nodongwe lweplastiki njenge-binder kunye ne-agent yeplastiki. Amandla ayo kwiqondo lokushisa elisezantsi, kwaye ukubunjwa kwe-ceramic bonding kwiqondo lokushisa eliphezulu kunamandla amakhulu.

Ngehydraulic, ukuqina komoya okanye izinto eziqinisa i-thermo njenge-binder, ebizwa ngokuba yi-chemical binding refractory mortar, njengoko kungaphantsi kokubunjwa kobushushu obubophezelayo be-ceramic phambi kokuveliswa kokusabela kweekhemikhali ezithile kunye nokuqina.

Iimbonakalo

Iimpawu zodaka lweRefractory: iplastiki elungileyo, ukwakhiwa okufanelekileyo; amandla ebhondi ephezulu, ukuxhathisa okuqinileyo kwe-corrosion; ukuchasa okuphezulu, ukuya kuthi ga kwi-1650℃±50℃; ukuchasana kakuhle nokuhlasela kwe-slag; ipropathi elungileyo yokuchitha amanzi.

Isicelo

Udaka lwe-refractory lusetyenziswa kakhulu kwi-oven ye-coke, i-oven yeglasi, isitovu esiqhumayo, isitovu esitshisayo, isinyithi, imveliso yezixhobo zokwakha, oomatshini, i-petrochemical, iglasi, ibhoyila, amandla ombane, intsimbi kunye nentsimbi, isamente kunye nezinye iziko loshishino.
