1. Cov ntxhia muaj pes tsawg
Lub ntsiab tseem ceeb yog cov ntsiab lus ntawm C3A thiab C4af. Yog tias cov ntsiab lus ntawm cov feem no yog tsawg, qhov sib xws ntawm cov xis thiab dej reducer yuav zoo, ntawm c3A muaj cov muaj zog muaj zog ntawm qhov yoog tau. Qhov no feem ntau yog vim tias cov dej reducer thawj ADSORBS C3A thiab C4af. Tsis tas li ntawd, kev ntsuas dej ntawm C3A yog muaj zog tshaj li ntawm C4af, thiab nws nce nrog kev nce ntawm txoj kev ua kom xis mas. Yog tias muaj ntau C3A cov khoom siv muaj nyob hauv cov cement, nws yuav ncaj qha rau cov dej me me uas yaj hauv sulfate, ua rau muaj kev txo qis ntawm cov sulfate ions produced.
2. FINENT
Yog tias cov xis mas yog qhov zoo, nws thaj chaw nto yuav loj, thiab cov flocculation yuav dhau los ua qhov pom tseeb. Txhawm rau kom tsis txhob muaj flocculation qauv, qee qhov nyiaj ntawm dej reducer xav tau ntxiv rau nws. Txhawm rau kom tau txais cov nyhuv txaus, nws yog qhov tsim nyog yuav tsum nce kev siv dej reducer rau qee yam. Nyob rau hauv ib txwm muaj xwm txheej, yog tias cov xis mas yog thaj chaw ntawm Cement yog qhov muaj ntau, ua rau muaj kev ua kom muaj kev ua kom muaj cov tshuaj xis. Yog li ntawd, nyob rau hauv cov txheej txheem tiag tiag ntawm kev teeb tsa qhob nrog lub siab cov dej sib piv, cov dej-rau-cov roj thiab cov roj dej kom muaj zog.
3. Kev hloov pauv ntawm Maas hais
Tus Cuam Tshuam ntawm Caas Paus yog kev hloov pauv ntawm cov ntsiab lus tsawg dua 3 microns, uas muaj cov txiaj ntsig zoo tshaj plaws ntawm cov adsorption ntawm dej reducers. Cov ntsiab lus ntawm cov ntsiab lus tsawg dua 3 microns nyob rau hauv txoj kev ntseeg tau ntau heev nrog cov Caas txawv hloov, thiab feem ntau tau faib ntawm 8-18%. Tom qab siv qhib cov txheej txheem qhib zeb, qhov tshwj xeeb thaj tsam ntawm cov xis kawm tau zoo dua qub ntawm kev yoog raws li cov txiv neej thiab cov dej ntws.
4. Roundness ntawm Maas hais
Muaj ntau txoj hauv kev los txhim kho kev sib tw ntawm cov cement. Yav dhau los, Maas hais tias yog feem ntau hauv av kom tsis txhob sib tsoo cov npoo thiab cov ces kaum. Txawm li cas los xij, nyob rau hauv cov txheej txheem ua haujlwm tiag tiag, muaj ntau ntawm cov hmoov zoo hmoov yog nquag tshwm sim, uas muaj qhov cuam tshuam ncaj qha rau kev ua haujlwm ntawm cov cement. Txhawm rau kom ua tau zoo no cov teeb meem no, hloov hlau pob sib tsoo tuaj yeem siv tau ncaj qha, txo cov kev ua haujlwm poob qis, thiab txo qis kev sib tsoo lub sijhawm sib tsoo. Tom qab roundness ntawm Maas hais tau txhim kho, txawm tias cov nyhuv rau cov redouric dej tsis loj heev, nws tuaj yeem txhim kho cov tshuaj pleev thaum xub thawj ntawm cov cement. Qhov tshwm sim no yuav pom tseeb thaum tus nqi ntawm cov reducer siv yog me me. Tsis tas li ntawd, tom qab kev txhim kho cov kev sib tw ntawm Caas hais, lub fws ntawm cov cement muab tshuaj kuj tseem tuaj yeem txhim kho rau qee yam.
5. Cov Khoom Siv Sib xyaw
Hauv kev siv cov cement tam sim no hauv kuv lub tebchaws, lwm cov ntaub ntawv feem ntau sib xyaw ua ke. Cov khoom siv sib xyaw no suav nrog cov cua sov ua kom sov, cov hmoov av thiab cov hmoov tshauv, thiab cov hmoov av tshauv tuaj yeem hloov kho tau Tau txais. Yog tias volcanic tshauv thiab thee gangue yog siv los ua cov khoom siv sib xyaw, nws yog qhov nyuaj kom tau txais kev sib xyaw zoo. Txhawm rau kom tau txais cov nyhuv dej kom zoo dua, muaj roj ntau dua. Yog tias ya tshauv lossis zeolite muaj nyob rau hauv cov khoom siv sib xyaw, qhov ploj ntawm kev tiv thaiv yog feem ntau cuam tshuam nrog lub rooj volcanic tshauv. Qhov tsawg dua qhov poob ntawm ignition, yuav tsum muaj dej ntxiv, thiab ntau dua lub roob hluav taws av tshauv. Tom qab kev xyaum ntau, nws tau raug pov thawj, nws tau raug pov thawj tias qhov yoog tau ntawm cov khoom xyaw rau cov cement thiab dej txo rau cov txiv neej ua kom muaj zog dua li cov Hloov tus nqi nce. ② Yog tias ya tshauv yog siv ncaj qha los hloov cov tshuaj Maste, nws lub fluidity pib tuaj yeem txo qis tom qab hloov cov khoom hloov tau ntau dua 30%. ③ Yog tias zeolite tau siv ncaj qha los hloov cov cement, nws yog qhov yooj yim los ua kom muaj cov tshuaj pleev tsis txaus thaum pib. Nyob rau hauv ib txwm muaj xwm txheej, nrog kev nce ntawm slag hloov tus nqi, qhov dej ntws rov qab los ntawm cov cement muab tshuaj txhuam. Thaum ya tshauv nce, qhov txaus poob ntawm tus paste yuav nce rau qee yam. Thaum cov Zeolite hloov tus nqi tshaj li 15%, qhov kev txaus siab poob ntawm cov tshuaj txhuam yuav pom tseeb.
6. Cov nyhuv ntawm admixture ntawm fluidity ntawm cov cement muab tshuaj txhuam
Los ntawm kev ntxiv qee qhov kev ua feem ntawm Insyctures rau cov pab pawg ua kom zoo nkauj, thiab cov pab pawg hydrophilic yuav taw rau cov kev daws teeb meem, yog li ua kom muaj txiaj ntsig zoo kos duab adsorption. Vim tias cov txiaj ntsig adsorption cov txiaj ntsig ntawm admixture, qhov saum npoo ntawm cov cement hais yuav raug foob ntawm tib lub cim. Nyob rau hauv cov nyhuv ntawm kev them nqi rov qab ib leeg, cov xis kawm yuav tso tawm ntawm cov dej hauv qab ntawm cov dej ntawm lub cev dej rau ib qho . Piv nrog rau lwm tus kws lij choj, lub ntsiab tseem ceeb ntawm polyhydroxy acid admin yog tias lawv tuaj yeem tsim pawg nrog cov kev cuam tshuam sib txawv ntawm cov saw hlau loj. Feem ntau, hydroxy acid admixtures muaj kev cuam tshuam ntau dua rau cov fluidity ntawm xis mas. Nyob rau hauv cov txheej txheem npaj ntawm high-zog ua vaj tse, ntxiv qee yam kev faib ua feem ntawm polyhydroxy acid admixtures tuaj yeem ua tiav cov txiaj ntsig zoo dua. Txawm li cas los xij, hauv cov txheej txheem ntawm kev siv polyhydroxy acid admixtures, nws muaj cov kev xav tau zoo ntawm kev ua tau zoo ntawm xis mas cov khoom siv raw. Hauv kev siv tiag tiag, cov sib tov yog nquag mus rau viscosity thiab sticking rau hauv qab. Hauv kev siv tom qab ntawm lub tsev, nws tseem muaj feem xyuam rau dej SWPAGE THIAB Stratification. Tom qab kev ua kom pom tseeb, nws tseem raug rau roughness, cov kab xuab zeb, thiab cov qhov cua. Qhov no yog ncaj qha cuam tshuam nrog qhov tsis sib xws ntawm polyhydroxy acid admixtures nrog cov cement thiab cov ntxhia mmixtures. Polyhydroxy acid admixtures yog confixtures nrog qhov zoo tshaj plaws kev yoog raws li txoj kev hloov pauv ntawm txhua hom kev lees paub.
