Phosphate hnav-resistant cib

Phosphate-consolidated high-aluminium hnav-resistant cib kuj tseem hu ua phosphate hnav-resistant phosphate hnav-resistant cib. Phosphate hnav-tiv cov cib yog ib yam khoom siv tsis zoo, uas yog cov khoom zoo bauxite clinker lossis ntom phosphoric acid daws raws li cov khoom siv tseem ceeb, lossis txhuas phosphate binder, Tom qab raug nias thiab tsim los ntawm lub tshuab qhuav, nws tau kho cua sov. ntawm 400-600 ℃ los ua cov khoom sib txuas ua cov khoom siv hluav taws xob. Nws yog ua ke nrog cov cib. Txhawm rau kom zam kev nqaim loj thaum siv cov khoom ntawm qhov kub thiab txias, cov khoom xyaw feem ntau yuav tsum tau nthuav qhia cov khoom siv cua sov nthuav dav, xws li kyanite, sillimanite, pyrophyllite, thiab silicon carbide. Sintered nrog cov av alumina siab thiab cov khoom siv hauv tsev, ua haujlwm rau tev tawm yog qhov zoo dua, tab sis qhov kub ua kom sov qis dua thiab tiv taus xeb, yog li me me ntawm fused corundum, mullite, thiab lwm yam. Raws li phosphoric acid thiab phosphoric acid resistant cib, refractory cib ua los ntawm cov cib alumina zoo tib yam los ntawm cov thev naus laus zis tshwj xeeb thiab tshuaj lom neeg ntxiv tau txhim kho kev txhim kho kev puas tsuaj thiab thauj khoom kub, siab dua cib alumina siab, lub zog zoo, txias sai thiab ua kom sov sai, Tiv taus tshuaj xeb thiab puas. Nws qhov tsos zoo dua li qhov siab alumina cib hauv cov cement rotary kilns.

Kev kawm:

(1) Kev ntsuas kub ua haujlwm tau zoo yog qhov ua kom sov siab dua 1770 degrees, tuaj yeem tiv taus qhov kub thiab txias, thiab kev hloov pauv hauv qhov kub tsis muaj qhov cuam tshuam loj.

(2) Zoo heev thermal stability, tiv taus kom txias sai thiab cua sov sai, thiab tsis muaj delamination lossis tev tawm hauv qhov kub hloov pauv.

(3) Tshuaj tsis haum, tsis muaj tawg thiab tev tawm yuav tshwm sim hauv Co cua ntawm qhov kub ntawm 400-600 ° C.

(4) Zoo hnav tsis kam thiab siab ua kom muaj zog.

Phosphate cib tau raug lees paub tias yog cov txheej txheej zoo rau cov cib kilns thiab cov txiv qaub.

Muaj ob hom phosphate-bonded siab alumina cib: ib qho yog phosphate-bonded high-alumina cib (hu ua cib phosphate), thiab lwm qhov yog phosphate-bonded high-alumina cib (hu ua cib-resistant)

Phosphate cib siv cov tshuaj phosphoric acid nrog cov ntsiab lus ntawm 42.5% mus rau 50% raws li phau ntawv, thiab cov khoom sib xyaw yog bauxite clinker calcined ntawm qhov kub siab tshaj 1600 ° C hauv qhov cub tawg. Thaum siv cov cib, phosphoric acid ua haujlwm zoo nrog cov hmoov bauxite zoo hauv cov cib kom ua haujlwm nrog cov av nplaum, thiab thaum kawg tsim cov ntawv nplaum tshwj xeeb ntawm cristobalite aluminium orthophosphate. Hnav-resistant cib siv muaj phosphoric acid thiab muaj aluminium hydroxide los npaj aluminium phosphate tov ua cov ntawv nplaum. Nws cov hniav sib piv yog Al2O3: P2O5 = 1: 3.2. Kev sib sau ua ke yog siv tib yam li cov phosphate cib. Hauv cov txheej txheem siv cov cib, zoo li phosphate, ib phau ntawv raws li cristobalite-type aluminium orthophosphate tau tsim.

Phosphate cib yog qhov tsim nyog rau lub qhov ncauj qhov ncauj ntawm thaj chaw hloov chaw ntawm cov kiav txhab rotary thiab lwm qhov chaw uas cov cib tau yooj yim ntog tawm, thiab nws kuj yog qhov zoo rau thaj chaw tua hluav taws. Nws kuj tseem siv rau hauv cov khoom siv hluav taws xob, lub qhov cub tawg, cov khoom lag luam carbon rotary kilns, thiab lwm yam.

Cov khoom ua tau zoo: Nws muaj cov yam ntxwv ntawm kev sib zog ua kom muaj zog ntawm chav sov, zoo thermal poob siab ruaj khov, siab load softening kub, qhov tseeb, qhov ntim siab ntom ntom, thiab hnav tsis kam zoo.
