Ob peb xyoos dhau los, kev tsim kho kev tsim kho tau muaj kev sib raug zoo heev thiab kev loj hlob. Qhov no tau tsim nyog rau kev txhim kho ntawm cov tshiab admixtures thiab ntxiv. Cov tshuaj ntxiv thiab cov tshuaj ntsuab rau cov pob zeb ua yog cov tshuaj lom neeg ntxiv rau hauv cov pob zeb ua kom nws lub cev nqaij daim tawv thiab tshuaj lom neeg. Cov khoom siv no sawv cev rau cov khoom sib txawv ntawm cov khoom lag luam sib txawv ntawm cov khoom siv tshuaj sib txawv.
Lub ntsiab sib txawv ntawm ADMIXTATURATE THIAB NTXIV yog cov theem ntawm cov tshuaj uas cov tshuaj yeeb tau ntxiv rau hauv av lossis xis mas. Cov ntxiv ntxiv nyob rau hauv cov cement tsim cov txheej txheem, thaum ntxiv rau ntawm Insixtures yog ua tiav thaum ua pob zeb ua vaj tse sib xyaw.
Dab tsi ntxiv yog ntxiv?
Cov ntxiv ntxiv rau cov cement thaum tsim khoom los txhim kho nws cov khoom. Feem ntau, cov ntaub ntawv nyoos nrog hauv CEMAS siv thiab xws li alumina, txiv qaub, hlau oxide, thiab silica. Tom qab sib tov, cov ntaub ntawv yog rhuab mus txog 1500 ℃ kom cia cov cement kom ua tiav nws cov tshuaj kawg kawg.
Inshixtures muaj dab tsi?
Admixtures rau cov pob zeb ua tau tuaj yeem yog ob hom, organic thiab inorganic sib xyaw. Multifunctional admixtures yog cov uas hloov kho ntau dua ib lub cev lossis tshuaj lom neeg ntawm cov qhob sib xyaw. Muaj ntau cov lus ntawm admixtures ntau yam muaj rau kev kho sib txawv ntawm cov pob zeb. Admixtures tuaj yeem faib rau hauv:
Dej ntws tawm admixtures
Cov no yog cov sib xyaw ua haujlwm ua cov yas ua haujlwm, uas txo cov dej hauv cov dej ntawm cov pob zeb ua kom sib xyaw kom ntau li ntau tau 5% tsis muaj kev hloov pauv nws li. Dej txo cov lus admixtures feem ntau yog polycyclic derivatives lossis phosphicates. Thaum ntxiv, cov assixtures nce ntxiv lub zog compressive ntawm lub pob zeb ua ke los ntawm ua nws ntau yas. Qhov no hom ntawm admixture yog feem ntau siv nrog pem teb thiab txoj kev pob zeb ua.
Muaj ntau cov dej muaj ntau
Cov no yog superplasticizers, feem ntau polymer qhob admixtures uas txo cov ntsiab lus dej los ntawm ntau li 40%. Nrog cov asmixtures no, lub porosity ntawm cov sib tov yog txo qis, yog li kev txhim kho nws lub zog thiab lub zog. Cov kws lij choj zoo no feem ntau siv rau kev sib cav tus kheej thiab txau ua pob zeb ua kom tawg.
Ua kom muaj kev qhuas
Cov qhob feem ntau yuav siv sijhawm los hloov ntawm cov yas rau lub xeev tawv. Polyethylene glycols, chlorides, nitrates, nitrates, thiab cov tshuaj fluoride feem ntau yog siv los ua cov kev hloov kho no. Cov tshuaj no tuaj yeem muab ntxiv rau cov pob zeb ua kom luv luv kom luv luv lub sijhawm nws yuav siv mus rau Bond thiab teeb tsa.
Cua-entraining admixtures
Cov kws tshaj lij no yog siv los ua cua tshuab ua pob zeb ua ke. Lawv pab tau kev sib txuam ntawm huab cua npuas rau hauv cov qhob sib tov sib xyaw xws li hloov cov khov-thaws los ntawm kev hloov ntawm cov cement.
Rov qab ua
Tsis zoo li kev ua kom nrawm rau cov neeg zoo siab uas tau ua kom luv luv thiab kev teeb tsa, rov ua kom zoo siab txhawb nqa lub sijhawm ua pob zeb ua kom tiav. Xws li ScixTures tsis hloov cov dej-Masen piv tab sis siv cov hlau oxides thiab cov suab thaj kom lub cev tab conditionically.
Qhob additives thiab admixtures yog tam sim no yog qhov zoo tshaj plaws ua cov qeb ntawm kev siv tshuaj. Ntawm JuaFU Chemtech, peb ua haujlwm nrog cov tuam txhab adminthture kom ntseeg tau tias peb cov neeg tau txais cov khoom lag luam zoo tshaj rau lawv cov haujlwm tsim kho. Txuas mus saib peb lub vev xaib mus saib thiab yuav cov kev ua tau zoo tshaj plaws thiab ntseeg vaj tse Additally thiab qhob admixtures thoob plaws. (HAIV NEEG
