High Purity Silicon Carbide Hmoov

 

Silicon hmoov yog cov khoom lag luam thaum lub sij hawm smelting ntawm ferrosilicon alloy los yog muaj silicon. Nws yog tau los ntawm oxidizing lub silicon chav tso tawm los ntawm lub flue thiab txias khaws plua plav. Silica hmoov muaj qhov ua tau zoo tshaj plaws ntawm tag nrho cov khoom sib xyaw, thiab kuj tseem kim tshaj plaws. Feem ntau tsuas yog siv nyob rau hauv high-strength, high-durability pob zeb.

Silicon (hlau) hmoov

 

Silica hmoov yog nkag rau hauv ob daim ntawv, uas yog thawj silicon hmoov thiab densified silicon hmoov.

1. Raw silicon hmoov, uas yog, cov khoom sib sau ncaj qha los ntawm cov khoom siv plua plav, muaj qhov ntim xoob li ntawm 150-200kg / m3. Raw silicon hmoov feem ntau yog thauj hauv hnab. Vim nws qhov ceev me me, kev thauj mus los ntev yog qhov tsawg, yog li siv Feem ntau cov neeg siv cov txheej txheem los ntawm cov hnab ntim ncaj qha thiab ncuav cov hmoov silica rau hauv cov pob zeb sib tov. Qhov chaw ua haujlwm yog plua plav thiab kev ua haujlwm tsis zoo.

 

2. Densified silicon hmoov. Txhawm rau daws qhov teeb meem uas cov hmoov silicon nyoos tsis haum rau kev thauj mus los ntev thiab muaj kev ua haujlwm tsawg, "micro-silicon density technology" tau tsim los txhim kho qhov xoob thiab ntom ntawm silicon hmoov. Cov tshuab no ua rau cov hmoov silicon qub yob thiab sib sau ua ke rau hauv cov khoom me me hauv qab qhov kev txiav txim ntawm cov cua compressed, yog li ua kom lub ntim xoob ntawm silicon hmoov mus rau 500-700kg / m3, uas pab txhawb kev siv thiab densifies me me ntawm silicon hmoov. Cov particle cohesion ntawm cov aggregate tsis muaj zog, thiab nws yooj yim heev rau disperse thaum lub sij hawm sib tov txheej txheem nyob rau hauv lub pob zeb tov khoom. Yog li ntawd, cov hmoov silicon hmoov tuaj yeem muab tso rau hauv lub tov khoom tom qab kev sib sau ua ke los xyuas kom meej tias qhov ntom ntom micro-silica particle aggregates yog dispersed thiab zoo dispersed.

 

 

Silica fume yog ntxiv rau pob zeb ua kom cov pob zeb ntom ntom, ua kom nws lub zog, thiab txhim kho nws cov khoom tiv thaiv permeability thiab tiv thaiv hnav. Cov txheej txheem rau kev sib xyaw silica fume: Feem ntau muaj ob txoj hauv kev ntxiv silica fume rau hauv pob zeb: ib qho yog kev sib xyaw sab hauv, thiab lwm qhov yog kev sib xyaw sab nraud, ob qho tib si yog siv nrog cov tshuaj txo cov dej.

 

High quality Silicon hlau hmoov

 

Txoj kev sib xyaw sab hauv feem ntau siv silica fume los hloov cov cement, uas tuaj yeem muab faib ua ob hom: sib npaug kom muaj nuj nqis hloov thiab hloov ib feem sib npaug. Qhov sib npaug sib npaug txhais tau hais tias cov ntsiab lus silica fume hloov qhov sib npaug ntawm cov cement, thiab kev hloov ib nrab txhais tau hais tias 1kg ntawm silica fume hloov 1 mus rau 3kg ntawm cov cement. Raws li kev tshawb fawb Cov koob tshuaj dav dav yog 5% mus rau 30%, thiab cov dej-cement piv feem ntau tseem tsis hloov pauv: txoj kev sib xyaw sab nraud yog hais txog cov hmoov silica uas tau muab sib xyaw rau hauv pob zeb zoo li cov khoom sib xyaw, tsis tas yuav txo cov cement ntau npaum li cas, thiab qhov ntau npaum li cas. Feem ntau 5% mus rau 10%, feem ntau cov khoom siv ntawm cov pob zeb tau txais los ntawm kev sib xyaw sab nraud yog ntau dua, tab sis cov khoom siv cementitious hauv cov pob zeb tau nce ntxiv.

Silica fume qhob yog siv rau hauv kev txuag dej thiab cov dej siv hluav taws xob los txhim kho kev puas tsuaj ntawm qhov project. Cov khoom siv tshuaj tiv thaiv kab mob hauv tsev thiab txawv teb chaws feem ntau siv cov ntaub ntawv polymer xws li epoxy mortar. Txawm hais tias cov khoom siv no muaj kev puas tsuaj zoo, nws txoj kev nthuav dav coefficient Nws yog ob peb zaug loj dua li cov pob zeb zoo tib yam ntawm lub hauv paus. Nws tsis haum zoo rau qhov kub ntawm lub hauv paus pob zeb. Nws yog ib qho yooj yim rau tawg thiab poob rau hauv tej yam ntuj tso huab cua. Kev tsim kho yog complex, lom thiab kim, yog li nws tsis tuaj yeem txhawb nqa thiab siv rau hauv thaj chaw loj. Los ntawm kev siv silica fume qhob, qhov kev tiv thaiv yaig yog nce li ntawm 1 zaug, thiab kev yaig tsis kam ntawm 48m / s ntws tus nqi nce ntau dua 3 zaug.
