Hlau oxide pigment rau cement pob zeb xim ntaub yas khoom

Kev Piav Qhia Luv:

Cov xim hlau oxide yog cov xim inorganic uas siv dav hauv ntau yam lag luam vim lawv cov khoom zoo heev, xws li xim ceev ceev, tshuaj lom neeg ruaj khov, thiab tiv taus huab cua.

Hauv kev lag luam kev tsim kho, lawv feem ntau siv los pleev xim rau cov pob zeb ua vaj tse, cib, thiab pob zeb paving. Los ntawm kev ntxiv cov xim hlau oxide, cov ntaub ntawv tsim kho no tuaj yeem ua tiav ntau yam xim, los ntawm cov xim liab thiab xim av mus rau daj, ua kom zoo nkauj ntawm cov qauv. Hauv cov xim thiab cov txheej txheem, cov xim hlau oxide ua haujlwm ua cov xim tseem ceeb - muab cov khoom. Lawv tsis tsuas yog muab cov xim nplua nuj thiab ci ntsa iab xwb tab sis kuj txhim kho qhov ruaj khov thiab tiv taus UV ntawm cov txheej txheem, tiv thaiv cov nplaim los ntawm kev ploj thiab kev puas tsuaj.

Kev lag luam tsheb siv cov xim hlau oxide los ua kom cov xim tiav ntawm lub tsheb, ua kom cov xim pleev xim ntev thiab zoo nkauj. Hauv kev lag luam yas, cov xim no raug ntxiv rau cov khoom yas xim, tswj lawv cov xim txawm tias nyob rau hauv qhov xwm txheej hnyav. Tsis tas li ntawd, cov xim hlau oxide pom siv rau hauv kev tsim cov kua mem rau kev luam ntawv, cov tshuaj pleev ib ce rau kev pleev xim, thiab cov khoom siv kos duab xws li xim thiab pastels, ua tsaug rau lawv tsis muaj tshuaj lom thiab ruaj khov.

Cov Khoom Qhia Txog Khoom

Cov Cim Npe Khoom

Zeolite yog lub npe dav dav rau cov minerals zeolite, uas yog ib hom alkali lossis alkaline earth hlau aluminosilicate mineral nrog dej. Ntau tshaj 40 hom zeolite ntuj tau pom thoob plaws ntiaj teb, ntawm cov uas clinoptilolite, mordenite, rhombic zeolite, maozeolite, calcium cross zeolite, schistose, turbidite, pyroxene thiab analcite yog cov feem ntau. Clinoptilolite thiab mordenite tau siv dav. Zeolite minerals koom nrog ntau lub cev siv lead ua, feem ntau yog fibrous, hairy thiab columnar, thiab ob peb yog phaj lossis luv columnar.

Zeolites muaj cov khoom ntawm kev sib pauv ion, adsorption thiab kev sib cais, catalysis, stability, tshuaj reactivity, reversible dehydration, conductivity, thiab lwm yam. Zeolites feem ntau yog tsim nyob rau hauv fissures lossis amygdaloids ntawm volcanic pob zeb, coexisting nrog calcite, pith thiab quartz, thiab tseem nyob rau hauv pyroclastic sedimentary pob zeb thiab kub springs deposits.

Zeolite hmoov yog ib hom zeolite ntuj, uas yog xim ntsuab thiab dawb. Nws tuaj yeem tshem tawm 95% ntawm ammonia nitrogen hauv dej, ua kom dej huv thiab txo qhov dej ntws.

Daim Ntawv Thov
Cov Khoom Ntxiv:Los ntawm kev ntxiv 5.0% (150 mesh) clinoptilolite hmoov rau hauv cov ntses pub, qhov kev ciaj sia thiab kev loj hlob ntawm cov nyom carp tuaj yeem nce ntxiv los ntawm 14.0% thiab 10.8%.
Kev txhim kho:Nws tuaj yeem tshem tawm 95% ntawm ammonia nitrogen thiab ntxuav cov dej kom huv.
Tus Neeg Thauj Khoom:Zeolite muaj ntau yam kev mob yooj yim rau tus neeg nqa khoom thiab tus neeg ua kom cov khoom sib xyaw ua ntej. Lub pH nruab nrab ntawm zeolite yog nruab nrab ntawm 7-7.5, thiab nws cov dej tsuas yog 3.4-3.9%. Ntxiv mus, nws tsis yooj yim rau kev cuam tshuam los ntawm cov dej noo thiab tuaj yeem nqus cov dej hauv cov ntsev inorganic thiab cov khoom me me uas muaj cov dej siv lead ua ke, yog li txhim kho qhov fluidity ntawm pub.
Cov khoom sib xyaw ua ke:Zeolite hmoov muaj qee qhov ntawm cov silica nquag thiab silica trioxide, uas tuaj yeem cuam tshuam nrog cov khoom hydrated calcium hydroxide ntawm cement los tsim cov tshuaj cementitious.
