Dab tsi yog alkali-free kua accelerator?
Jan 07, 2025
BDS alkali-dawb kua accelerator yog ib hom accelerator haum rau kev siv cov pob zeb txau. Nws yog dawb ntawm alkali thiab aluminates, ua kom ceev ceev thiab hardening ntawm pob zeb. Cov khoom no txhim kho lub zog thaum ntxov, txo qis rov qab poob, thiab ua kom muaj adhesion siab. Nrog nws cov yam ntxwv tsis muaj plua plav, cov kua accelerator yog ib puag ncig tus phooj ywg, muab kev tiv thaiv corrosion zoo heev.
Yam khoom qauv
Hom Tsis-reactive: Txo qhov kev pheej hmoo ntawm alkali cov tshuaj tiv thaiv, txo lub zog poob ntawm cov pob zeb txau, txhim khu kev ruaj khov, thiab tuaj yeem siv rau cov haujlwm ntev.
Ceev ceev hom: Ceev ceev lub sij hawm teem caij ntawm cov pob zeb txau, kom ntseeg tau tias lub zog ua tau raws li lossis tshaj lub teb chaws cov qauv, ua kom yooj yim rau kev tsim kho.
Hom kev lag luam: Tsim los rau cov pob zeb txau nrog cov nqi rov qab qis dua 10%, txo cov khoom siv thiab cov nqi zog, muab kev lag luam zoo.
Environmentally Friendly: Thaum lub sij hawm txau, nws tsis muaj plua plav lossis cov pa phem, ua kom muaj kev noj qab haus huv ntawm cov neeg ua haujlwm thiab txo cov khoom pov tseg.
Technical Indicators
| Performance Index | Txuj | Kev Xeem |
|---|---|---|
| Cov ntsiab lus chloride ion (%) | Tsawg dua los yog sib npaug rau 0.1 | 0.02 |
| Cov ntsiab lus Alkali (%) | Tsawg dua los yog sib npaug li 5 | 2.35 |
| Slump Retention (min) | Ntau dua lossis sib npaug 7 | 7.5 |
| Compressive zog (1d) | Ntau dua lossis sib npaug rau 7.0 MPa | 8.6 |
| Compressive zog (28d) | Ntau dua lossis sib npaug li 10 MPa | 12.5 |
Khoom siv
- Cov khoom no yog cov kua sib xyaw nrog cov mis tsis muaj alkali. Nws yuav tsum tau muab sib xyaw rau hauv lub pob zeb sib xyaw ua ke ua ntej thov.
- Qhov ntau npaum li cas yuav tsum tau txiav txim siab raws li dej-rau-cement ratios, tshauv cov ntsiab lus, thiab lwm yam. Kev sib cuam tshuam ntawm lub cev thiab tshuaj lom neeg ua kom lub zog ua haujlwm tau zoo.
- Tau tshaj ntau yam ntaub ntawv thiab ua rau kom muaj zog thaum ntxov thiab mus sij hawm ntev durability ntawm sprayed qhob.
- Pab txhim kho cov kav ntev thiab lub cev ntawm cov pob zeb txau thaum tswj kev nyab xeeb ib puag ncig.
Cov cheeb tsam thov
- Underground Projects: Mining tunnels, txoj kev tunnels, dej tunnels, subway tej yaam num, thiab lwm yam kev tsim kho.
- Pob zeb thiab av Reinforcement: Pob zeb slopes, foundations, reservoirs, dams, embankments, thiab cov phab ntsa tuav dej.
- Kho tej yaam num: Kho kab teeb, piers, tunnels, reservoir, dikes, thiab lwm yam kev puas tsuaj los ntawm av qeeg, hluav taws kub, thiab kev puas tsuaj ntuj tsim. Haum rau kev txhim kho pob zeb thiab masonry.
- Tiv thaiv hluav taws: Fireproof coatings rau ntau yam qauv thiab sealing ntawm cov dej xau.
- Cov haujlwm ua haujlwm ntev: Txhim kho thiab txhim kho cov chimneys thiab lwm cov kav dej kub.
Teeb meem xav tau kev saib xyuas
- Cov khoom no yog weakly corrosive. Tsis txhob kov ncaj qha rau ntawm daim tawv nqaij lossis qhov muag. Yog tias muaj kev sib cuag, yaug tam sim nrog dej huv.
- Tsis txhob dilute cov kua accelerator nrog dej; siv raws li muab.
Packing thiab Cia
Lub alkali-dawb accelerator yog tsis muaj zog hygroscopic thiab yuav tsum tau muab kaw thaum lub sij hawm cia. Nws raug pom zoo kom khaws cia ntawm 5-35 degree rau lub sijhawm siab tshaj plaws ntawm rau lub hlis. Siv cov khoom tam sim tom qab qhib kom ntseeg tau tias kev ua haujlwm zoo.
