Simende yeCalcium Alumina

Simende yeCalcium Alumina: Mumiriri Ane Simba weBonding kune Zvaunoda Muindasitiri

Kana zvasvika pazvinhu zvekusimbisa simende,Simende yeCalcium Alumina(CAC) inoonekwa sesarudzo yakavimbika uye inoshanda. Yakagadzirwa nemusanganiswa webauxite, limestone, uye calcined clinker ine calcium aluminate sechinhu chikuru, iyi hydraulic cementing material inopa simba rinoshamisa uye kushanduka-shanduka. Huremu hwayo hwealumina hunosvika 50% hunoipa hunhu hwakanaka hwekubatanidza, zvichiita kuti ive sarudzo inokosha mumaindasitiri akasiyana-siyana.

Sumo pfupi：

CAC, inozivikanwawo se aluminate simende, inowanikwa mumavara akasiyana, kubva payero nebrown kusvika kugrey. Kusiyana uku kwemavara kunoita kuti ive nyore kushandisa, sezvo ichigona kusanganiswa nezvinhu zvakasiyana-siyana uye pamusoro. Ungave uchishanda pakugadzira simbi, petrochemical, kana simende,Simende yeCalcium Aluminainoratidza kuti ndiyo nzira yakanakisisa yekubatanidza zvinhu.

Zvakanakira:

Chimwe chezvakanakira zvikuru zveCalcium Alumina Cement isimba rayo rinoshamisa. Muumbirwo wayo wakasiyana unovimbisa nzira yekukurumidza uye inoshanda yekupisa, zvichikugonesa kuwana mhedzisiro inogara kwenguva refu. Ungave uri kuvaka zvivakwa zvemaindasitiri kana kugadzirisa zvivakwa zviripo, hunhu hwakasimba hweCAC hunovimbisa kubatana kwenguva refu uye kwakavimbika.

Pamusoro pekusimba kwayo, CAC ine simba rekudzivirira kupisa kwakanyanya, zvichiita kuti ive yakakodzera kushandiswa mumaovheni nemaovheni. Kugona kwayo kutsungirira kupisa kwakanyanya kunoita kuti mapurojekiti ako ekuvaka kana kugadzirisa arambe aripo kunyangwe mumamiriro ezvinhu akaoma. Chinhu ichi chinobatsira zvikuru mumaindasitiri uko kugadzikana kwekupisa kwakakosha pakushanda zvakanaka uye kuchengetedzeka.

Uyezve, Calcium Alumina Cement inopa simba rekudzivirira makemikari zvakanyanya, zvichiita kuti ive sarudzo yakakodzera kune nzvimbo dzinosanganisira kusangana nezvinhu zvinoparadza kana zvinhu zvinokuvadza. Kuumbwa kwayo kwakasimba kunodzivirira kuora kunokonzerwa nekuita kwemakemikari, zvichiita kuti zvinhu zvako zvirambe zviripo kwenguva refu. Izvi zvinonyanya kukosha mumaindasitiri uko kuchengetedza kuvimbika kwezvishandiso nezvivakwa ndiko kwakakosha zvikuru.

Tichifunga nezvemakwikwi emaindasitiri, kushanda zvakanaka uye kubereka zvakakosha kuti zvinhu zvibudirire. Calcium Alumina Cement inopawo mukana panyaya iyi. Hunhu hwayo hwekukurumidzira uye kukura kwayo nesimba rekutanga kunoderedza nguva yekuvaka uye kunovandudza nguva yepurojekiti. Nekushandisa CAC, unogona kuchengetedza nguva nezvinhu zvakakosha uku uchivimbisa mhedzisiro yepamusoro.

Chinhu：

CalciumAlumina Cementsets inokurumidza. Simba re1d rinogona kusvika anopfuura 80% yesimba repamusoro, rinonyanya kushandiswa kumapurojekiti ekukurumidzira, akadai sekudzivirira nyika, migwagwa uye mapurojekiti ekugadzirisa akakosha.

Kupisa kweCalciumAlumina Cementing kwakakura uye kuburitsa kupisa kwacho kwakawanda. Kupisa kwemvura kunoburitswa mu1d i70% kusvika 80% yehuwandu hwese, zvekuti tembiricha yemukati mekongiri inokwira zvakanyanya, kunyangwe kana kuvaka kwacho kuri pa -10 ° C, CalciumAlumina Cement inogona kukurumidza kuomarara, uye inogona kushandiswa kumapurojekiti ekuvaka munguva yechando.

Mumamiriro ezvinhu akajairwa ekuomesa, CalciumAlumina Cement ine simba rekudzivirira ngura yesulfate nekuti haina tricalcium aluminate uye calcium hydroxide, uye ine density yakakura.

CalciumAlumina Cement ine simba rekudzivirira kupisa zvakanyanya. Zvakadai sekushandisa zvinhu zvinodzivirira kupisa (zvakaita sechromite, nezvimwewo) zvinogona kugadzirwa nekongiri inodzivirira kupisa ine tembiricha ye1300 ~ 1400℃.

Zvisinei, simba renguva refu nezvimwe zvinhu zveCalcium Alumina Cement zvine tsika yekudzikira, simba renguva refu rinodzikira neinenge 40% kusvika 50%, saka Calcium Alumina Cementi haina kukodzera zvivakwa nemapurojekiti anotakura mutoro kwenguva refu munzvimbo dzinopisa zvakanyanya uye dzine hunyoro hwakawanda, yakakodzera chete kumainjiniya ehondo ekukurumidzira (kuvaka migwagwa, mabhiriji), mabasa ekugadzirisa (kuvharira, nezvimwewo), mapurojekiti enguva pfupi, uye kugadzirira kongiri inodzivirira kupisa.

Pamusoro pezvo, kusanganiswa kweCalciumAlumina Cement nesimende yePortland kana lime hakungogumiri pakusimbisa, asiwo kunoita kuti simende ipwanyike uye iparare nekuda kwekuumbwa kwecalcium aluminate ine alkaline yakawanda. Saka, pamusoro pekusanganiswa nelime kana simende yePortland panguva yekuvaka, haifanirwe kushandiswa kana yakabatana nesimende yePortland isina kuoma.

Mukupedzisa, Calcium Alumina Cement inopa musanganiswa wesimba, kushanduka-shanduka, uye kusimba, zvichiita kuti ive sarudzo inodiwa kune zvinodiwa zvemaindasitiri ekubatanidza. Ungave uri kuita zvesimbi, petrochemicals, kana kugadzira simende, CAC inovimbisa mhedzisiro yakanaka. Hunhu hwayo hwekukurumidzira, simba rayo rekutanga, uye kuramba kupisa kwakanyanya uye makemikari zvinoita kuti ive chinhu chakakosha mune chero chirongwa. Sarudza Calcium Alumina Cement kuti uwane mhinduro dzekubatanidza dzine simba uye dzakavimbika dzinogara kwenguva refu.
