Mimwe michina yekutenderera kwemaindasitiri kwenguva yakareba mu900 ℃-1100 ℃ tembiricha yebasa, refractory zvinhu patembiricha iyi yakaoma kuwana ceramic sintering state, inokanganisa zvakanyanya mashandiro ezve refractory, sodium hexametaphosphate mune refractory castable, pfapfaidza mune inoshanda. kuita kwebhenefiti isimba rakagadzika rakanaka rekumanikidza uye kupfeka kuramba uye kupisa kutyisa kuramba, Chinhu chinobatsira kusimbisa inosunga chimiro che refractories, kubvumira powdery kana granular refractories kusunganidza pamwe chete kuratidza simba rakakwana.
Mune iyo yakareba inogadzira kutenderera michina, bhailer, semuenzaniso, nekuda kwekupisa kwechikamu che fluidization velocity, tembiricha yakakwira yechoto chebira refractory ine kukukurwa kwakasimba, kupfeka, kunyanya munzvimbo dzakaita senge boiler yekupisa kamuri uye separator dutu pasi pezviyo, kuyerera kwemhepo uye. Kusvuta kwepakati kupfeka uye kupisa kwekushisa, kunotungamira mukudonha kwe lining, kupera, kubvarura uye kudonha, Zvinokanganisa zvakanyanya kushanda kwakajairika uye kugadzirwa. zvemaboilers.
Naizvozvo, zvinodikanwa kugadzira mhando nyowani yebhainda ine yakanyanya tembiricha kuramba, kukukurwa kwevhu, kusagadzika kwekusapfeka uye kupisa kwekushomeka kwekushisa kuvandudza kushanda kwezvinhu zvinoramba.
Sodium hexametaphosphate ine zvakanakira mukushandiswa kwerefractory castable, spray filler, kuburikidza nekusarudzwa kweiyo kuumbwa reshiyo uye gadziriro yegadziriro parameters, binder ndeyekumiswa uye kuparadzira hurongwa ine kwaakarerekera pH kukosha, kwete chete kunamatira kwakasimba uye kusaora kune simbi. matrix, yakakwirira tembiricha kuramba uye isiri-inorganic binder application tembiricha yakafara. Sodium hexametaphosphate inoiswa hydrolyzed kuita sodium dihydrogen phosphate (NaH2PO4) kana ichishandiswa sebhainda mune refractory castable uye spray filler.
NaH2PO4 uye alkaline pasi simbi oxides, yakadai semagnesia, inogona kuita pane imwe tembiricha kuti iite Mg (H2PO4) 2 uye MgHPO4, iyo inogona kuderedzwa kuita magnesium phosphate [Mg (PO3) 2] N uye [Mg2 (P2O7)] N zvakateerana nekupisa pa500 ℃. Simba rekubatanidzwa rinowedzera kuvandudzwa. Iyo ine simba repamusoro pamusoro petembiricha yakakura (kusvika 800 ℃) isati yatangazve chikamu chemvura.
Sodium hexametaphosphate inonyanya kushandiswa sebhainda remagnesia uye magnesia chrome zvidhinha zvisina kupiswa, zvinokandwa uye zvekutanga kupfura zvinhu. Mukugadzirira kwekukandwa, kusungirirwa kwemushonga wayo wemvura unofanirwa kusarudzwa 25% ~ 30% yakakodzera, uye huwandu hwekuwedzera hunowanzo 8% ~ 18%. Pasi pemamiriro ekuvimbisa kushanda kwemusanganiswa, inofanira kushandiswa zvishoma sezvinobvira kuti ive nechokwadi chekushanda kwekushisa kwepamusoro kwezvinhu. Iyo coagulant inogona kunge iri aluminate simende kana zvimwe zvinhu zvine calcium.
Refractory zvinhu zvakakosha zvakakosha zvesimbi nesimbi, zvekuvaka, zvisiri-ferrous simbi, petrochemical, michina, magetsi emagetsi, kuchengetedza kwezvakatipoteredza uye mamwe maindasitiri ekupisa. Sodium hexametaphosphate binder zvakare chinhu chakakosha chakakosha zvinhu zvakasiyana-siyana zvepamusoro-tembiricha maindasitiri ekupisa uye zvishandiso.
