Kev siv cov vermiculite
Siv rau thermal rwb thaiv tsev
Expanded vermiculite muaj cov yam ntxwv ntawm kev ntxhib los mos, lub teeb yuag thiab siab melting point, thiab yog qhov zoo tshaj plaws rau cov ntaub ntawv rwb thaiv tsev kub (hauv qab 1000 ℃) thiab cov khoom siv hluav taws xob rwb thaiv tsev.Lub kaum tsib-centimeter-thick cement vermiculite board tau hlawv ntawm 1000 ℃ rau 4-5 teev, thiab qhov kub ntawm sab nraub qaum tsuas yog li 40 ℃.Lub xya-centimeter tuab vermiculite slab tau hlawv ntawm qhov kub ntawm 3000 ℃ rau tsib feeb los ntawm cov nplaim hluav taws kub-welded nplaim net.Sab pem hauv ntej yaj, thiab sab nraub qaum tseem tsis sov los ntawm tes.Yog li nws tshaj tag nrho cov ntaub ntawv rwb thaiv tsev.Xws li asbestos thiab diatomite khoom.
Vermiculite tuaj yeem siv los ua cov ntaub ntawv thermal rwb thaiv tsev hauv cov chaw kub kub, xws li thermal rwb thaiv tsev cib, thermal rwb thaiv tsev boards thiab thermal rwb thaiv tsev caps hauv kev lag luam smelting.Txhua yam khoom siv uas yuav tsum tau thermal rwb thaiv tsev tuaj yeem insulated nrog vermiculite hmoov, cement vermiculite khoom (vermiculite cib, vermiculite daim hlau, vermiculite kav, thiab lwm yam) los yog asphalt vermiculite khoom.Xws li cov phab ntsa, lub ru tsev, qhov chaw txias txias, boilers, chav kav dej, cov kav dej ua kua, cov kav dej, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom txaus ntshai, thiab lwm yam.
Siv rau suab rwb thaiv tsev txheej
Vermiculite nthuav dav vim qhov tsim ntawm cov huab cua zoo sib txawv, tsim cov khoom siv rwb thaiv tsev ntxeem tau, thaum zaus ntawm 2000C / S, vermiculite thickness 5 hli thaum lub suab nqus ntawm 63%, lub thickness ntawm vermiculite 6 hli thaum lub suab absorbing tus nqi ntawm 84. %, vermiculite Lub suab nqus yog 90% thaum lub pob zeb tuab yog 8 hli.
Rau cov chaw tiv thaiv hluav taws xob
Vermiculite tuaj yeem nqus tau hluav taws xob.Lub phaj vermiculite tau teeb tsa hauv chav kuaj tuaj yeem hloov cov phaj siab nqi siab kom nqus tau cov hluav taws xob tawg los ntawm 90%.Lub thickness ntawm vermiculite yog 65 hli, uas yog sib npaug rau 1 hli txhuas phaj.
Rau kev cog qoob loo
Vim hais tias vermiculite hmoov muaj dej zoo, huab cua permeability, adsorption, looseness, tsis hardening thiab lwm yam khoom, thiab nws yog sterile thiab non-toxic tom qab kub kub roasting, uas yog conducive rau rooting thiab kev loj hlob ntawm cov nroj tsuag.Nws tuaj yeem siv rau kev cog qoob loo, cog qoob loo thiab txiav cov paj thiab ntoo, zaub, txiv hmab txiv ntoo thiab txiv hmab txiv ntoo, nrog rau kev ua paj chiv thiab cov av zoo.
Manufacturing rau chemical coatings
Vermiculite muaj kev tiv thaiv corrosion rau acid, ntawm 5% los yog tsawg dua ntawm sulfuric acid, hydrochloric acid, acetic acid, 5% aqueous ammonia, sodium carbonate, anti-corrosive nyhuv.Vim nws lub teeb yuag, xoob, smoothness, loj txoj kab uas hla-rau-thickness piv, muaj zog adhesion, thiab kub tsis kam, nws kuj siv tau los ua ib tug muab tub lim nyob rau hauv kev tsim cov xim (cov xim tsis muaj hluav taws kub, cov xim pleev xim, cov xim tsis muaj dej. ) txhawm rau tiv thaiv cov xim Tiav thiab xa cov khoom ua haujlwm.
Rau cov khoom sib txhuam
Expanded vermiculite muaj cov ntawv zoo li thiab thermal rwb thaiv tsev, tuaj yeem siv rau cov ntaub ntawv sib txhuam thiab cov khoom siv braking, thiab muaj kev ua tau zoo, tsis muaj tshuaj lom thiab tsis muaj mob, thiab yog cov khoom siv tshiab rau ib puag ncig cov pa phem.
