Cov tshauv ya Ceramsite yog ua los ntawm cov tshauv ya ua cov khoom siv tseem ceeb (kwv yees li 85%), sib xyaw nrog cov txiv qaub (lossis calcium carbide slag), gypsum, admixtures, thiab lwm yam. Ib qho khoom sib xyaw ua los ntawm cov tshuaj hydraulic ntuj. Ceramsite muaj cov khoom zoo heev, xws li qhov ceev qis, lub tog raj kheej siab compressive zog, porosity siab, coefficient softening siab, zoo frost tsis kam, thiab zoo alkali-resistant aggregate reactivity. Tshwj xeeb tshaj yog vim qhov ceev qis ntawm ceramsite, qhov sab hauv porousness, cov duab sib xws thiab cov khoom sib xyaw, thiab qee lub zog thiab firmness, nws muaj qhov zoo ntawm qhov hnyav sib dua, corrosion tsis kam, frost tsis kam, av qeeg tsis kam thiab rwb thaiv tsev zoo (kev khaws cia kub, rwb thaiv tsev kub, rwb thaiv tsev suab, rwb thaiv tsev, thiab lwm yam). dej ntws) thiab lwm yam ntxwv ntau yam. Siv cov khoom zoo heev ntawm ceramsite, nws tuaj yeem siv dav hauv cov ntaub ntawv tsim kho, kev cog qoob loo, zaub mov thiab dej haus, cov ntaub ntawv rwb thaiv tsev refractory, kev lag luam tshuaj lom neeg, roj av thiab lwm yam. Thaum pib ntawm kev tsim khoom thiab kev tsim khoom ntawm ceramsite, nws tau siv dav hauv kev ua haujlwm ntawm cov ntaub ntawv tsim kho. Vim yog kev txhim kho thev naus laus zis tas mus li thiab tib neeg nkag siab tob txog cov khoom ntawm ceramsite, daim ntawv thov ntawm ceramsite twb dhau qhov kev siv ib txwm muaj ntawm cov ntaub ntawv tsim kho, thiab nws daim ntawv thov tau nthuav dav tas mus li. teb. Tam sim no daim ntawv thov ntawm ceramsite hauv cov ntaub ntawv tsim kho tau poob qis los ntawm 100% mus rau 80%, thiab daim ntawv thov hauv lwm yam tau suav txog 20%. Nrog rau kev txhim kho tas mus li ntawm kev siv tshiab ntawm ceramsite, nws qhov sib piv hauv lwm yam yuav maj mam nce ntxiv.
Cov khoom ntawm cov tshauv ya ceramsite
Qhov laj thawj uas ua rau cov tshauv ya ceramsite tau tsim kho sai thoob plaws ntiaj teb yog vim nws muaj ntau yam khoom zoo heev uas lwm cov ntaub ntawv tsis muaj. Cov khoom zoo no ua rau nws tsis tuaj yeem hloov pauv los ntawm lwm cov ntaub ntawv. Cov khoom zoo no muaj cov hauv qab no.
1. Qhov ceev tsawg thiab lub teeb yuag. Qhov ceev ntawm cov tshauv ceramsite nws tus kheej yog tsawg dua 1100kg / m3, feem ntau 300-900kg / m3. Qhov ceev ntawm cov pob zeb ua los ntawm cov tshauv ceramsite ua cov khoom sib sau ua ke yog 1100-1800kg / m3, thiab lub zog sib xws ntawm cov pob zeb yog 30.5-40.0Mpa. Qhov tshwj xeeb tshaj plaws ntawm ceramsite yog tias nws nyuaj rau sab nraud, thiab muaj ntau lub micropores sab hauv. Cov micropores no muab ceramsite nws cov khoom sib dua. Qhov ceev ntawm No. 200 tshauv ceramsite pob zeb yog li 1600kg / m3, thaum qhov ceev ntawm cov pob zeb ib txwm nrog tib lub npe yog siab txog 2600kg / m3, thiab qhov sib txawv ntawm ob yog 1000kg / m3.
2. Kev rwb thaiv tsev thiab kev rwb thaiv cua sov. Vim nws sab hauv uas muaj qhov porous, cov tshauv ya ceramsite muaj cov khoom rwb thaiv tsev zoo. Lub thermal conductivity ntawm cov pob zeb ua los ntawm nws feem ntau yog 0.3 txog 0.8 W/(m·k), uas yog 1 txog 2 zaug qis dua li ntawm cov pob zeb ib txwm muaj. Yog li ntawd, cov tsev ceramsite muaj ib puag ncig zoo thermal.
3. Kev tiv thaiv hluav taws zoo, ceramsite muaj kev tiv thaiv hluav taws zoo heev. Cov tshauv ya ceramsite pob zeb lossis cov tshauv ya ceramsite thaiv kev sib xyaw ua ke thermal rwb thaiv tsev, av qeeg tiv thaiv, tiv thaiv te, tiv thaiv hluav taws thiab lwm yam khoom, tshwj xeeb tshaj yog qhov tiv thaiv hluav taws yog ntau dua 4 npaug ntawm cov pob zeb ib txwm muaj. Rau tib lub sijhawm refractory, qhov tuab ntawm cov pob zeb ceramsite yog 20% thinner dua li ntawm cov pob zeb ib txwm muaj. Tsis tas li ntawd, cov tshauv ya ceramsite kuj tseem tuaj yeem npaj cov pob zeb refractory nrog refractoriness hauv qab 1200 ℃. Ntawm qhov kub siab ntawm 650 ° C, cov pob zeb ceramsite tuaj yeem tswj tau 85% ntawm lub zog ntawm chav tsev kub. Cov pob zeb ib txwm tuaj yeem tswj tau 35% txog 75% ntawm nws lub zog ntawm chav tsev kub.
4. Kev ua tau zoo ntawm av qeeg. Cov pob zeb ceramsite muaj kev ua tau zoo ntawm av qeeg vim nws qhov hnyav sib dua, cov qauv elastic qis thiab kev tiv taus deformation zoo.
5. Kev nqus dej tsawg, tiv taus te zoo thiab ruaj khov. Cov kua qaub, alkali corrosion thiab kev ua haujlwm tiv taus te ntawm cov ceramsite concrete zoo dua li cov ceramsite ib txwm muaj. Rau No. 250 fly ash ceramsite concrete, lub zog poob ntawm 15 lub voj voog khov-thaw tsis pub ntau tshaj 2%. Ceramsite concrete yog cov khoom siv hauv tsev zoo heev thiab yuav tsum tau txhawb nqa thiab siv.
