Expanded perlite yog lub lightest ntawm tag nrho cov ntxhia aggregates haum rau pob zeb. Rwb thaiv tsev thiab lub teeb yuag, perlite-aggregate qhob yog siv rau ntau yam kev tsim kho thiab cov khoom lag luam - suav nrog lub ru tsev decks, chimney linings, statuary, zoo nkauj pob zeb, pobzeb mortars, roj qhov cub cav, hauv pem teb systems thiab sau, roj cia tank, insulating tank thiab pas dej ua ke hauv paus, thiab txhawm rau txhawb lub suab thiab hluav taws-tiv taus hauv cov phab ntsa, pem teb thiab cov qauv hlau.
PerlitePob zeb
Thaum siv los ua qhov sib xyaw ua ke hauv pob zeb, nthuav dav perlite muab ntau qhov zoo rau kev tsim kho thiab kev tsim khoom siv precast. Txawm hais tias lub teeb yuag perlite pob zeb tsis yog feem ntau haum rau cov qauv siv los yog cov khoom siv thauj khoom, hauv lwm daim ntawv thov nws muab kev txhim kho hauv kev ntxhov siab, txo suab nrov, kev hloov pauv thermal, thiab kev ntsuas hluav taws.
Feem ntau hais lus, perlite pob zeb tuaj yeem muab faib ua ob pawg - Ultralight thiab Lightweight. Ultralight perlite pob zeb muaj qhov ntom ntom tsawg dua 50 lbs / ft3 (800 kg / m3) thiab feem ntau yog siv rau lub ru tsev decks, tsa cov txaj cog, kab hlau rhuav phab ntsa, thiab daim ntawv thov rwb thaiv tsev ruaj khov xws li liquefied natural gas (LNG) cia tso tsheb hlau luam. Lub teeb yuag perlite pob zeb muaj qhov ntom ntom ntawm 50 txog 110 lb / ft3 (800 - 1800 kg / m3), suav nrog microsilica xuab zeb, thiab muaj zog compressive thiab flexural zog, ua rau nws tsim nyog hauv pem teb tiav thiab sau. Nyob rau hauv ob qho tib si, kev siv cov cua-entraining tus neeg saib xyuas txhim kho kev ua haujlwm, muab kev ceev ceev, thiab khaws cov nqi rwb thaiv tsev.
Perlite hauv Well Cements
Perlite lub peev xwm los tuav cov cua sov muab cov khoom siv sib xyaw ua ke zoo uas ua rau pom cov khoom poob qis vim nws lub peev xwm los txuas cov voids thiab foob pob tawg. Lwm qhov zoo muaj xws li cov txiaj ntsig loj dua ntawm qhov sib zog sib zog, qhov zoo ntawm insulating zoo, cov yam ntxwv zoo ntawm cov dej tsis zoo, thiab txo qis hydrostatic siab ntawm ib puag ncig tsim.
Perlite Insulating Concrete rau ru tsev Decks
Cov txheej txheem rwb thaiv tsev tsis zoo yog qhov nyuaj thiab nyuaj rau nruab thiab tuaj yeem poob txog 30% ntawm lawv cov ntaub ntawv pov thawj vim yog cov khoom shrinkage, thermal drift, thiab thermal bridging hla steel lawj los ntawm cov neeg kho tshuab fasteners. Tsis muaj teeb meem zoo li no nrog perlite pob zeb ru tsev decks. Perlite pob zeb ru tsev decks yog seamless, muab ib tug du, txawm monolithic puag rau ncaj-adhered vov tsev daim nyias nyias. Perlite pob zeb tuaj yeem muab tso rau ntawm qhov chaw galvanized steel decking, precast lossis poured-in-qhov chaw ua vaj tse, los yog txawm tshaj suab nrov vov tsev cov ntaub ntawv.
Perlite pob zeb yog lub hauv paus zoo tshaj plaws rau kev tsim thiab ib-ply vov tsev. Nws muaj zog cua thiab hluav taws kub, thiab, nrog rau ntxiv ntawm polystyrene rwb thaiv tsev sandwiched nyob rau hauv lub perlite pob zeb, siab thermal kuj tseem ceeb yog economically tiav. Qhov tshwm sim: lub ru tsev zoo kawg nkaus uas yuav thaiv thiab tiv thaiv hluav taws rau lub neej ntawm lub tsev. Re-ru tsev tsuas yog ib qho teeb meem ntawm kev hloov daim nyias nyias.
Perlite qhob mix formulations tuaj yeem tsim nrog qhov ntom ntawm 20 mus rau 50 lbs / ft3, lub ntsiab lus perlite pob zeb ru tsev lawj nrog R-30 kev ntsuas tuaj yeem nyob hauv qab 8 lbs. ib square feet.
Lwm qhov kev txiav txim siab hauv kev ua si: perlite pob zeb ru tsev lawj systems tau yooj yim sloped rau cov kua dej; qhov hluav taws kub ntawm 1 mus rau 3 teev yog ua tau; Lub teeb yuag perlite pob zeb tuaj yeem siv tau, nchuav, lossis plastered rau hauv qhov chaw; kho perlite pob zeb tuaj yeem raug ntsia, sawn, thiab ua haujlwm nrog cov cuab yeej raug.
Kev sim thiab kev pom zoo. Perlite pob zeb ru tsev lawj rwb thaiv tsev tshuab tau raug sim thiab pom zoo rau kev ntsuas cua thiab hluav taws los ntawm Underwriters Laboratories, Hoobkas Mutual, thiab lwm yam cai tswj hwm. Perlite pob zeb ru tsev decks nrog polystyrene rwb thaiv tsev board ua tau raws li cov qauv rau UL Class 90 thiab FM 1-90 cua tsis kam.
Tsim cov khoom siv pob zeb zoo nkauj
Qhov zoo tshaj plaws ntawm kev siv cov perlite nthuav dav sib sau ua ke hauv kab lis kev cai (tsim) pob zeb thiab cib veneer cov khoom yog qhov hnyav txuag - ntau npaum li ib feem peb ntawm qhov hnyav tshaj li cov qauv sib xyaw. Qhov kev txuag hnyav ntawd muaj qhov zoo meej: cov qauv kev txhawb nqa tsis tshua muaj zog (xws li ledges thiab footings) rau lub veneer, thiab kev txuag nqi hauv kev tuav thiab xa khoom.
Perlite qhob cov khoom siv hluav taws xob thiab hluav taws kub-resistant kuj ntxiv tus nqi rau cov khoom siv pob zeb, pab ncaj qha mus rau qhov sib npaug ntawm cov khoom siv hluav taws xob ntawm lub tsev.
Feem ntau hais lus, sib tov tsim rau perlite aggregate-raws li kab lis kev cai pob zeb khoom sib txawv ntawm 1: 4 (binder: perlite) mus rau 1: 20 los ntawm ntim.
Insulating Cia Tank thiab Pas Dej Bass
Perlite qhob cov khoom zoo tshaj plaws insulative tiag tiag tuaj rau hauv kev ua si thaum siv los ua lub hauv paus rau cov khoom siv hluav taws xob hloov hluav taws xob-resistant cia tso tsheb hlau luam thiab hauv av vinyl pas dej ua ke. Rau cov pas dej da dej hauv av tshwj xeeb, kev poob cua sov hauv av tau txo qis, yog li muab lub pas dej zoo sib xws-dej kub thiab txo cov khoom siv cua sov. Kev ua haujlwm du ntawm lub pas dej perlite pob zeb muab lub hauv paus ruaj khov, seamless foundation rau vinyl pas dej ua ke - thiab tus yuam sij rau lub neej ntev ntawm cov ntaub.
Cov qauv sib xyaw tsim qauv sib txawv ntawm 1: 5 (binder: perlite) mus rau 1: 8, nrog rau qhov sib piv ntau dua ntawm perlite muab cov thermal conductivity ntau dua. Qhov tsawg kawg nkaus lub hauv paus tuab ntawm ob nti (5cm) yog qhov tsim nyog kom ua tiav lub zog thiab cov txiaj ntsig insulative.
