Cov txheej txheem ntawm kev siv cov hmoov micro-silica hauv Al magnesium txau ntxiv
1, tus nqi ntawm micro-silica hmoov
(1) Kev sib xyaw ua ke: nyob rau hauv qhov chaw ntawm tib cov dej ntxiv, 1 feem ntawm silica hmoov tuaj yeem hloov 3-5 qhov chaw ntawm cov cement (qhov hnyav) thiab khaws lub zog compressive ntawm txhuas magnesium tshuaj tsuag ntxiv tsis hloov los txhim kho lwm yam khoom ntawm aluminium magnesium spray ntxiv.
(2) Kev sib xyaw: cov cement tsis hloov pauv, thiab qhov sib ntxiv ntawm micro-silica hmoov ua kom muaj zog thiab lwm yam khoom ntawm Al-Mg tshuaj tsuag ntxiv. Muaj qee qhov poob qis thaum cov tshuaj txhuas-magnesium txau ntxiv yog tov nrog micro-silica hmoov. Qhov no yuav tsum tau muab sau tseg nyob rau hauv lub mix ratio. Microsilica hmoov yuav tsum tau ua ke nrog dej txo tus neeg sawv cev. Nws raug nquahu kom ntxiv cov tshauv ya thiab nplua slag txhawm rau txhim kho nws txoj haujlwm.
(3) Qhov hnyav piv nrog cov khoom siv gel: Thaum npaj aluminium magnesium txau ntxiv nrog micro-silica hmoov, qhov hnyav piv nrog cov khoom siv cementing feem ntau: kev ua haujlwm siab ua vaj tse yog 5-10%; Hydraulic qhob yog 5-10%; Shotcrete yog 5-10%; Pump pab yog 2-3%; Hnav-resistant industrial pem teb yog 6-8%; Polymer mortar, thermal rwb thaiv tsev mortar: 10-15%; Lub amorphous refractory castable yog 6-8%. Ua ntej siv, thov xaiv qhov tsim nyog thiab kev noj nyiaj txiag raws li qhov xav tau tiag tiag los ntawm kev sim.
2. Ntxiv txoj kev ntawm micro-silica hmoov
Micro-silica hmoov txhuas-magnesium tshuaj tsuag ntxiv yuav tsum tau ua los ntawm kev sim siv sib xyaw. Kev tsim kho kom nruj raws li qhov sib xyaw ua ke. Hauv kev sib xyaw ntawm micro-silica hmoov txhuas-magnesium tshuaj txau, micro-silica hmoov yuav tsum tau muab ntxiv rau hauv lub tov khoom tam sim tom qab noj tag nrho. Muaj ob hom txheej txheem rau kev koom nrog:
(1) Muab tso rau hauv qhov sib xyaw ua ke, tom qab ntawd muab tso rau hauv cov hmoov micro-silica, cov cement qhuav, thiab tom qab ntawd ntxiv dej thiab lwm yam khoom sib xyaw.
(2) Muab cov sib xyaw ntxhib +75% dej + micro-silica hmoov +50% hmoov sib xyaw, do rau 15-30 vib nas this, thiab tom qab ntawd muab tso rau hauv cement + admixture +50% fine aggregate +25% dej, do kom txog thaum sib tov. Lub sij hawm nplawm yog 20-25% lossis 50-60 vib nas this ntev tshaj li qhov zoo tib yam aluminium-magnesium spray ntxiv. Tsis txhob ntxiv silica hmoov rau cov tshuaj Al-Mg sib xyaw.
Raws li cov nyhuv ntawm micro-silica hmoov ntawm cov khoom ntawm Al-magnesium tshuaj tsuag ntxiv, nws tuaj yeem kwv yees tias cov tshuaj tsuag ntub dej ntxiv nrog cov ntsiab lus ntawm cov hmoov micro-silica qis yuav qhia tau zoo dua yaig tsis kam thiab spilling tsis kam, thiab yog li muaj kev pabcuam ntev dua. lub neej. Micro-silica hmoov yuav tsum tau ua nruj me ntsis raws li cov kev tsim kho tshwj xeeb ntawm cov pob zeb engineering, tab sis vim tias cov hmoov micro-silica yog lub teeb, nws yog nruj me ntsis txwv tsis pub pov cov ntaub ntawv ntawm qhov siab kom tiv thaiv micro-silica hmoov los ntawm ya. Anyang Jiashike Hlau Co., Ltd. ntau lawm thiab kev loj hlob zoo silica fume (micro silica hmoov), zus tau tej cov silica fume hais, kev ua tau zoo, dav siv, txais tos yuav tawm lus los yog hu rau kev sib tham.
