Vermiculite Board
Kev piav qhia
Vermiculite board yog tsim los ntawm kev nthuav dav vermiculite thiab ib qho koob tshuaj, uas yog ua los ntawm cua sov lossis txias siab. Tom qab cua sov kub txog 1200 ° C, nws tsis tsim cov pa roj uas ua rau tib neeg kev noj qab haus huv, thiab kev ua haujlwm combustion tau mus txog Class A. Nrog rau lawv cov thermal rwb thaiv tsev zoo heev, hluav taws kub tsis kam, lub teeb yuag, thiab cov khoom siv suab nrov, lawv tau siv dav hauv kev tsim kho, horticulture, kev ua liaj ua teb, thiab ntau yam kev lag luam. Txawm hais tias nws yog rau rwb thaiv tsev, tiv thaiv hluav taws, lossis kev daws teeb meem acoustic, vermiculite rwb thaiv tsev boards muaj kev ua tau zoo thiab pab txhawb rau kev siv hluav taws xob, kev nyab xeeb, thiab kev nplij siab hauv ntau hom kev siv.
Vermiculite board yog nyias-walled hollow structural khoom uas tsis muaj zog thiab tsawg melting point. Nws qhov hluav taws kub tsis kam thiab kev ua haujlwm kub siab yog qis dua li lwm cov khoom siv hluav taws xob zoo. Refractory board yog ua los ntawm ntau yam sib xyaw los yog sib sau ua ke thiab ib lossis ntau cov nplaum. Cov hmoov sib xyaw ua ke uas muaj cov tshuaj sib xyaw yuav tsum sib xyaw nrog ib lossis ntau cov kua dej thaum siv, thiab muaj zog fluidity.

Hluav taws kub Resistance:Vermiculite board yog cov hluav taws kub-resistant, ua rau lawv xaiv rau kev tiv thaiv hluav taws. Lawv muaj lub siab melting point thiab tsis emit cov pa phem thaum raug kub. Qhov no ua rau lawv tsim nyog siv rau hauv kev thaiv hluav taws, qhov rooj hluav taws, thiab lwm yam kev tsim hluav taws kub.
Lub teeb yuag thiab yooj yim rau kov:Vermiculite rwb thaiv tsev boards yog lub teeb yuag, ua rau lawv yooj yim los tuav thiab nruab. Lawv qhov hnyav hnyav txo qhov hnyav tag nrho ntawm cov qauv, ua rau lawv tsim nyog rau cov ntawv thov uas txwv qhov hnyav lossis kev xav txog kev thauj khoom yog qhov tseem ceeb.
Suab Absorption:Vermiculite boards muaj cov khoom siv suab nrov zoo, pab txo cov suab nrov kis tau tus mob thiab txhim kho kev ua haujlwm acoustic. Lawv feem ntau yog siv rau hauv lub tsev partitions, ceilings, thiab soundproof enclosures los tsim ib tug ntsiag to thiab xis nyob ib puag ncig.
Chemical Resistance:Vermiculite rwb thaiv tsev boards pom zoo tiv thaiv ntau yam tshuaj, nrog rau cov kua qaub, alkalis, thiab cov kuab tshuaj organic. Qhov no ua rau lawv tsim nyog siv rau hauv cov chaw ua tshuaj, cov chaw soj nstuam, thiab lwm qhov chaw uas muaj tshuaj tiv thaiv yog qhov tseem ceeb.

Khoom FAQ
Qhov txawv ntawm vermiculite cib thiab refractory cib yog ua los ntawm cov khoom sib txawv:
Qhov zoo ntawm vermiculite fireproof board yog raws li nram no:
1. Vermiculite board yog nplaim-retardant, tshav kub-insulating, suab-insulating thiab ib puag ncig tus phooj ywg, thiab nws cov cim ntau yam yog superior rau lwm cov fillers.
2. Vermiculite hluav taws kub boards yog lub teeb nyob rau hauv hnyav. Noj cov qhov rooj hluav taws ntawm tib qhov kev qhia tshwj xeeb thiab qib tiv thaiv hluav taws ua piv txwv, qhov hnyav ntawm vermiculite qhov rooj hluav taws tsuas yog ib nrab ntawm qhov hnyav ntawm nws cov khoom siv ib txwm siv. Lub teeb yuag ntawm lub qhov rooj hluav taws txhais tau hais tias lub nra ntawm lub pob khawm yog qhov tsawg, uas txo qhov kev puas tsuaj thaum siv, ua kom lub neej ntev ntawm lub qhov rooj hluav taws, thiab txuag cov nqi kho.
3. Vermiculite fire board Ntoo qhov rooj hluav taws ua los ntawm vermiculite fireproof board muaj ib tug smoother nto thiab tsis muaj blistering.
Qhov zoo ntawm refractory bricks:
1. Refractory bricks yog cov khoom siv refractory zoo heev. Ntawm ntau cov ntaub ntawv refractory, qhov zoo ntawm refractory cib tuaj yeem hais tias yog qhov zoo tshaj plaws. Refractory bricks tsis tau tsuas yog muaj cov khoom zoo refractory, tab sis kuj muaj kev hnav siab heev.
2. Zoo thermal conductivity Thermal conductivity yog lwm qhov zoo dua ntawm refractory cib. Nws thermal conductivity ceev yog ze ze rau lub pores ntawm refractory cib. Cov pores loj yuav ua kom sov sai dua, thiab cov pores me yuav ua kom sov sai dua. yuav qeeb.
3. Lub neej ua haujlwm ntev: Refractory bricks muaj lub neej ua haujlwm ntev. Hauv lwm lo lus, refractory bricks muaj kev cuam tshuam zoo heev.
4. Muaj zog corrosion kuj: Castables thiab refractory bricks muaj zog corrosion kuj thiab tsis yooj yim puas, uas txhais tau hais tias refractory bricks muaj zog slag kuj.
