Fly ash ceramsite yog dab tsi?

ya tshauvceramsite yog ua los ntawm cov tshauv ya raws li cov khoom siv tseem ceeb (kwv yees li 85%), sib xyaw nrog cov kua qaub (lossis calcium carbide slag), gypsum, admixtures, thiab lwm yam. Ib qho khoom siv sib xyaw ua ke ua los ntawm cov tshuaj tiv thaiv hydraulic.Ceramsite muaj cov khoom zoo heev, xws li lub tog raj kheej tsawg, siab ntso muag ua kom muaj zog, thiab zoo nkauj heev ntawm alkali-resistant conginal reactivity.Tshwj xeeb tshaj yog vim qhov tsis tshua muaj siab ntawm ceramsite, qhov porousness sab hauv, cov duab zoo ib yam thiab muaj pes tsawg leeg, thiab qee lub zog thiab ruaj khov, nws muaj qhov zoo ntawm lub teeb yuag, corrosion kuj, Frost tsis kam, av qeeg tsis kam thiab zoo rwb thaiv tsev (kub preservation, tshav kub. rwb thaiv tsev, suab rwb thaiv tsev, rwb thaiv tsev, thiab lwm yam).tide) thiab lwm yam multifunctional nta.Siv cov khoom zoo heev ntawm ceramsite, nws tuaj yeem siv dav hauv cov khoom siv hauv tsev, horticulture, zaub mov thiab dej haus, cov ntaub ntawv rwb thaiv tsev refractory, tshuaj lom neeg kev lag luam, roj av thiab lwm yam sectors.Thaum pib ntawm invention thiab zus tau tej cov ceramsite, nws yog tsuas yog siv nyob rau hauv lub teb ntawm lub tsev cov ntaub ntawv.Vim muaj kev txhim kho txuas ntxiv ntawm thev naus laus zis thiab tib neeg kev nkag siab tob txog cov khoom ntawm ceramsite, daim ntawv thov ntawm ceramsite twb dhau los ntawm cov khoom siv hauv tsev, thiab nws daim ntawv thov tau txuas ntxiv mus.teb.Tam sim no daim ntawv thov ntawm ceramsite hauv cov khoom siv hauv tsev tau nqis los ntawm 100% mus rau 80%, thiab daim ntawv thov hauv lwm yam tau suav txog 20%.Nrog kev txhim kho txuas ntxiv ntawm kev siv tshiab ntawm ceramsite, nws qhov kev faib ua feem hauv lwm yam yuav maj mam nce.

Cov khoom ntawm yoov tshauv ceramsite

Yog vim li cas ya tshauv ceramsite tau tsim sai heev thoob plaws lub ntiaj teb no yog tias nws muaj ntau yam zoo heev uas lwm yam ntaub ntawv tsis muaj.Cov cuab yeej zoo no ua rau nws hloov tsis tau los ntawm lwm cov ntaub ntawv.Cov khoom zoo heev no muaj cov nram qab no.
1. Tsawg ceev thiab lub teeb yuag.Qhov ceev ntawm ya tshauv ceramsite nws tus kheej yog tsawg dua 1100kg / m3, feem ntau 300-900kg / m3.Qhov ntom ntawm cov pob zeb ua nrog ya tshauv ceramsite raws li kev sib sau ua ke yog 1100-1800kg / m3, thiab qhov sib xyaw ua ke compressive zog yog 30.5-40.0Mpa.Qhov loj tshaj plaws ntawm ceramsite yog tias nws nyuaj rau sab nraud, thiab muaj ntau micropores sab hauv.Cov micropores no muab ceramsite nws lub teeb-hnyav zog.Qhov ntom ntawm No. 200 ya tshauv ceramsite pob zeb yog hais txog 1600kg / m3, thaum qhov ceev ntawm cov pob zeb zoo tib yam nrog tib daim ntawv lo yog siab li 2600kg / m3, thiab qhov sib txawv ntawm ob yog 1000kg / m3.
2. Rwb thaiv tsev thiab rwb thaiv tsev kub.Vim nws qhov ntxeem tau ntawm sab hauv, ya tshauv ceramsite muaj cov thermal rwb thaiv tsev zoo.Lub thermal conductivity ntawm pob zeb npaj nrog nws feem ntau yog 0.3 txog 0.8 W / (m·k), uas yog 1 mus rau 2 npaug qis dua li cov pob zeb zoo tib yam.Yog li ntawd, cov vaj tse ceramsite muaj qhov chaw zoo thermal.
3. Cov hluav taws kub zoo, ceramsite muaj hluav taws kub zoo heev.Ordinary ya tshauv ceramsite pob zeb los yog ya tshauv ceramsite thaiv integrates thermal rwb thaiv tsev, av qeeg tsis kam, Frost tsis kam, hluav taws kub thiab lwm yam khoom, tshwj xeeb tshaj yog cov hluav taws kub tiv taus ntau tshaj 4 npaug ntawm cov pob zeb zoo tib yam.Rau tib lub sijhawm refractory, lub thickness ntawm ceramsite pob zeb yog 20% ​​thinner dua li cov pob zeb zoo tib yam.Tsis tas li ntawd, ya tshauv ceramsite tseem tuaj yeem npaj cov pob zeb refractory nrog refractoriness hauv qab 1200 ℃.Ntawm qhov kub ntawm 650 ° C, cov pob zeb ua pob zeb tuaj yeem tuav tau 85% ntawm lub zog ntawm chav tsev kub.Ordinary qhob tsuas tuaj yeem tswj tau 35% mus rau 75% ntawm nws lub zog ntawm chav tsev kub.
4. Kev ua haujlwm zoo seismic.Ceramsite pob zeb muaj kev ua tau zoo seismic vim nws lub teeb yuag, tsis tshua muaj elastic modulus thiab zoo deformation kuj.
5. Tsis tshua muaj dej nqus, zoo Frost tsis kam thiab kav ntev.Cov kua qaub, alkali corrosion thiab Frost tsis kam ua haujlwm ntawm ceramsite pob zeb zoo dua li cov pob zeb zoo tib yam.Rau No. 250 ya tshauv ceramsite pob zeb, lub zog poob ntawm 15 lub voj voog khov-thaw tsis ntau tshaj 2%.Ceramsite pob zeb yog cov khoom siv hauv tsev zoo heev thiab yuav tsum tau txhawb nqa thiab siv.
