Perlite nthuav dav yog cov pob zeb sib xyaw ua ke uas sib dua tshaj plaws uas tsim nyog rau cov pob zeb ua vaj tse. Cov pob zeb perlite uas muaj rwb thaiv tsev thiab sib dua yog siv rau ntau yam kev tsim kho thiab cov khoom lag luam - suav nrog cov ru tsev, cov ntaub thaiv qhov cub, cov duab puab, cov pob zeb dai kom zoo nkauj, cov vuas pobzeb, cov ntoo hluav taws roj, cov tshuab hauv pem teb thiab cov khoom sau, cov thoob roj cia, lub thoob rwb thaiv tsev thiab cov hauv paus pas dej ua ke, thiab los txhawb cov khoom siv suab thiab hluav taws hauv phab ntsa, pem teb thiab cov hlau ua vaj tse.
Perlite Pob zeb ua vaj tse
Thaum siv ua cov khoom sib xyaw ua ke hauv cov pob zeb ua vaj tse, cov perlite nthuav dav muab ntau qhov zoo tseem ceeb rau kev tsim kho thiab kev tsim khoom ua ntej. Txawm hais tias cov pob zeb perlite sib dua feem ntau tsis haum rau kev siv cov qauv lossis kev thauj khoom, hauv lwm daim ntawv thov nws muab kev txhim kho hauv kev ntxhov siab ntawm lub nra, txo suab nrov, tiv taus kev hloov pauv thermal, thiab qib hluav taws.
Feem ntau hais lus, cov perlite concrete muaj peev xwm muab faib ua ob pawg - Ultralight thiab Lightweight. Ultralight perlite concrete muaj qhov ceev tsawg dua 50 lbs/ft3 (800 kg/m3) thiab feem ntau yog siv rau cov ru tsev, cov txaj cog qoob loo, cov phab ntsa ntaub thaiv, thiab cov ntawv thov rwb thaiv tsev tas mus li xws li cov thoob dej cia roj liquefied natural gas (LNG). Cov perlite concrete sib dua muaj qhov ceev ntawm 50 txog 110 lb/ft3 (800 - 1800 kg/m3), suav nrog cov xuab zeb microsilica, thiab muaj lub zog compressive thiab flexural siab, ua rau nws tsim nyog rau kev ua tiav hauv pem teb thiab kev sau. Hauv ob hom, kev siv cov neeg sawv cev cua-entraining txhim kho kev ua haujlwm tau zoo, muab kev tswj hwm qhov ceev, thiab khaws cia tus nqi rwb thaiv tsev.
Perlite hauv cov cement zoo
Perlite lub peev xwm los tswj cua sov muab cov khoom siv cementing sib dua thiab tsis hnyav heev uas tsis tshua muaj kev poob khoom vim nws muaj peev xwm txuas cov qhov khoob thiab kaw cov pob tawg. Lwm yam zoo suav nrog cov qoob loo ntau dua ntawm qhov ceev sib dua, cov yam ntxwv rwb thaiv tsev, cov yam ntxwv poob dej zoo heev, thiab qhov siab hydrostatic qis dua ntawm cov qauv ib puag ncig.
Perlite Insulating Concrete rau Ru Tsev
Cov txheej txheem rwb thaiv tsev uas ruaj khov feem ntau nyuaj rau teeb tsa thiab tuaj yeem poob txog li 30% ntawm lawv cov nqi rwb thaiv tsev uas tau tshaj tawm vim yog cov khoom me me, kev hloov pauv ntawm cua sov, thiab kev sib txuas ntawm cua sov hla lub lawj hlau los ntawm cov khoom siv kho tshuab. Tsis muaj teeb meem zoo li no nrog cov ru tsev perlite. Cov ru tsev perlite yog cov khoom tsis muaj qhov sib txuas, muab lub hauv paus du, txawm tias monolithic rau cov ntaub ntawv ru tsev uas lo ncaj qha. Cov pob zeb perlite tuaj yeem muab tso rau saum cov hlau galvanized slotted, precast lossis poured-in-place concrete, lossis txawm tias hla cov ntaub ntawv ru tsev uas twb muaj lawm.
Cov pob zeb perlite yog lub hauv paus zoo tshaj plaws rau cov txheej txheem ru tsev uas tau tsim thiab ib txheej. Nws muaj kev tiv taus cua thiab hluav taws zoo dua, thiab, nrog rau kev ntxiv cov polystyrene rwb thaiv tsev uas tau muab tso rau hauv cov pob zeb perlite, cov nqi tiv taus cua sov siab tau ua tiav kev lag luam. Qhov tshwm sim: lub ru tsev ruaj khov heev uas yuav rwb thaiv tsev thiab tiv taus hluav taws rau lub neej ntawm lub tsev. Kev rov ua dua ru tsev tsuas yog ib qho teeb meem ntawm kev hloov daim nyias nyias.
Cov qauv sib xyaw ua ke ntawm perlite tuaj yeem tsim nrog qhov ceev ntawm 20 txog 50 lbs / ft3, txhais tau tias lub ru tsev perlite concrete nrog qhov ntsuas R-30 tuaj yeem muaj qis dua 8 lbs. ib square foot.
Lwm yam kev xav uas yuav tsum xav txog: cov txheej txheem perlite concrete ru tsev tau yooj yim rau kev ntws dej; qhov ntsuas hluav taws kub tau txij li 1 txog 3 teev; cov pob zeb perlite sib dua tuaj yeem raug twj, nchuav, lossis plastered rau hauv qhov chaw; cov pob zeb perlite kho tau tuaj yeem raug ntsia hlau, sawn, thiab ua haujlwm nrog cov cuab yeej ib txwm muaj.
Kev Xeem thiab Kev Pom Zoo. Cov txheej txheem rwb thaiv tsev perlite concrete ru tsev tau raug sim thiab pom zoo rau qhov ntsuas cua thiab hluav taws los ntawm Underwriters Laboratories, Factory Mutual, thiab lwm cov koom haum tswj hwm. Cov ru tsev perlite concrete nrog polystyrene rwb thaiv tsev ua tau raws li cov qauv rau UL Class 90 thiab FM 1-90 tiv taus cua.
Cov Khoom Siv Pob Zeb Kho Kom Zoo Nkauj Uas Tsim Tawm
Qhov zoo tshaj plaws ntawm kev siv cov perlite uas nthuav dav hauv cov pob zeb thiab cov khoom siv veneer uas tau cog qoob loo (tsim tawm) yog qhov hnyav uas txuag tau - ntau npaum li ib feem peb ntawm qhov hnyav dua li cov qauv sib xyaw ib txwm muaj. Qhov kev txuag qhov hnyav ntawd muaj cov txiaj ntsig meej meej: cov qauv txhawb nqa uas tsis nruj heev (xws li cov ntaiv thiab cov hauv paus) rau veneer, thiab txuag nqi hauv kev tuav thiab xa khoom.
Cov khoom siv perlite concrete uas tiv taus hluav taws thiab tiv taus cua sov kuj ntxiv tus nqi rau cov khoom siv pob zeb cog qoob loo, pab ncaj qha rau qhov sib npaug ntawm kev hloov pauv cua sov ntawm lub tsev.
Feem ntau hais lus, cov qauv sib xyaw rau cov khoom siv pob zeb perlite uas ua los ntawm cov pob zeb muaj txij li 1:4 (binder:perlite) txog 1:20 los ntawm qhov ntim.
Lub Taub Hau Khaws Khoom Thiab Cov Hauv Paus Pas Dej Ua Los Ntawm Cov Khoom Uas Rwb Thaiv Tsev
