Perliteyog ib qho tshwm sim siliceous pob zeb siv rau thermal rwb thaiv tsev hauv tsev.

Ntau lawm
Tebchaws Asmeskas yog lub ntiaj teb cov neeg tsim khoom loj tshaj plaws thiab cov neeg siv khoom ntawm perlite. Lwm lub tebchaws uas tsim cov perlite suav nrog Tuam Tshoj, Tim Nkij teb chaws, Nyiv, Hungary, Armenia, Ltalis, Mexico, Philippines, thiab Qaib Cov Txwv. Koj tuaj yeem paub tias nws yog cov pob zeb me me uas siv hauv cov av potting los txhim kho aeration thiab noo noo khaws cia.

Tom qab nws tau mined, perlite yog rhuab mus rau kwv yees li 1,600 ° F (871 ° C), uas ua rau nws cov ntsiab lus dej vaporize thiab tsim myriad me npuas npuas uas suav nrog cov ntxhia hauv lub cev tshwj xeeb. Perlite rwb thaiv tsev yog tsim nyob rau hauv ib daim ntawv granular raws li ib tug hmoov daim ntawv, tab sis ib co manufacturers muab nws nrog gypsum los yog lwm yam ntaub ntawv los tig nws mus rau hauv ib tug insulating board. Ntxiv rau nws siv los ua ib qho insulator hauv cov tsev, perlite yog siv rau rwb thaiv tsev ntawm cov khoom siv kub qis, xws li super-txias cia thiab cryogenic tso tsheb hlau luam, nrog rau hauv cov ntawv thov zaub mov.

Lub cev muaj zog thiab kev txheeb xyuas

Rwb thaiv tsev nyob hauv tsev tuaj yeem ua los ntawm perlite yog tias nws muaj cov hauv qab no zoo:
nws cov daus dawb mus rau greyish-dawb nyob rau hauv cov xim. Cov pob zeb crude xws li pob tshab lub teeb grey mus rau glossy dub, tab sis daim ntawv nthuav dav pom hauv tsev tau yooj yim txheeb xyuas los ntawm nws cov xim dawb;
nws yog lub teeb. Kev nthuav dav perlite tuaj yeem tsim los hnyav li 2 phaus ib cubic taw; thiab/los yog
nws qhov ntau thiab tsawg yuav txawv, tab sis lawv feem ntau tsis loj dua ¼-inch inch.

Perlite's Performance li Insulator

Perlite yog dav siv raws li xoob-sau rwb thaiv tsev, tshwj xeeb tshaj yog nyob rau hauv masonry tsim, vim hais tias ntawm cov nram qab no zoo uas ua rau nws ntshaw:
tsawg toxicity. Raws li lub koom haum Perlite, "Tsis muaj qhov kuaj pom lossis cov ntaub ntawv qhia tias perlite ua rau muaj kev phom sij rau kev noj qab haus huv." Lwm cov insulators, xws li asbestos, vermiculite (uas yuav muaj asbestos), thiab fiberglass muaj kev phom sij ntau dua;
tshuaj inertness, txhais tau tias nws yuav tsis corrode piping, hluav taws xob los yog kev sib txuas lus conduits. Perlite muaj pH ntawm ib ncig ntawm 7, uas zoo ib yam li cov dej tshiab;
kev ua tau zoo. Raws li ib tug xoob-fill insulator nyob rau hauv masonry kev tsim kho, perlite yuav tsum tau nchuav rau hauv cov kab noj hniav ntawm cov pob zeb thaiv qhov twg nws tag nrho cov crevices, cores, mortar cheeb tsam thiab pob ntseg qhov. Cov pob zeb hauv av yuav ntws los ntawm ib qho roughness, unevenness lossis raug teeb tsa. Nws txhawb nws tus kheej qhov hnyav thiab yuav tsis nyob los yog choj; Perlite cement
hluav taws kub ntsuas. Underwriters Laboratories tau pom tias qhov ntsuas ob-teev, 8-nti (20.32-cm) pob zeb thaiv phab ntsa tau txhim kho mus rau plaub teev thaum cores tau ntim nrog silicone-kho perlite;
lwj - thiab vermin-resistant;
suab attenuation. Perlite xoob-sau rwb thaiv tsev muaj peev xwm sau tag nrho cov voids, mortar kab thiab pob ntseg qhov, yog li ua kom nws txo cov suab nrov ntawm cov phab ntsa. Lub teeb yuag, 8-nti (20-cm) masonry thaiv uas muaj perlite ua tiav lub suab kis tau tus mob ntawm 51, tshaj HUD suab kis tus qauv;
noo noo-resistant, ua kom muaj txiaj ntsig zoo rau kev siv hauv thaj chaw raug dej los yog dampness, xws li hauv pem teb leveling tebchaw thiab hauv pem teb rwb thaiv tsev; thiab
txhua yam ntuj tsim. Tsoomfwv Meskas Lub Tsev Haujlwm Saib Xyuas Kev Ruaj Ntseg tau tawm tswv yim perlite ua cov khoom siv ntsuab.
Qee cov ntawv thov rau perlite ua ib qho insulator hauv cov tsev suav nrog:

nyob rau hauv lub cores ntawm hollow-masonry unit phab ntsa;
nyob rau hauv kab noj hniav ntawm masonry phab ntsa;
nruab nrab ntawm sab nrauv masonry phab ntsa thiab sab hauv furring;
rau hauv pem teb rwb thaiv tsev thiab leveling ntawm qub pem teb. Nyob rau hauv daim ntawv thov no, perlite rwb thaiv tsev yog poured rau hauv pem teb thawj nto, screeded rau qhov tob kom zoo, them nrog corrugated cardboard los yog lub teeb boards, thiab ib tug txheej ntawm daim ntawv roj;
hauv qab nthab vuas;
raws li fireproofing nyob ib ncig ntawm lub chimneys, qhov rooj, chav tsev thiab kev nyab xeeb; thiab
rau lub ru tsev decking.
Kev txwv

Nrog rau R-tus nqi ntawm 2.7, perlite under-ua lwm yam insulators, xws li fiberglass, rockwool thiab cellulose. Nws ua tau zoo dua lwm tus, txawm li cas los xij, xws li vermiculite, cov khoom siv ntoo xoob, thiab straw.
Perlite tsis siv tau rau cov ntawv thov uas nws yuav raug ncaj qha mus rau qhov kub thiab txias ntawm 200 ° F.
Perlite yuav tsum tsis txhob siv rau ntawm qhov chaw sab nrauv uas tsis tu ncua raug dej lossis dej noo. Yog xav tau kev sib cuag nrog dej ntau dhau los yog noo noo, Portland cement plaster yog pom zoo.
Perlite plasters tsis pom zoo tshaj cov cua kub cua sov vim tias lawv cov nqi insulating.
Qhov kub siab tshaj plaws uas perlite tuaj yeem tiv taus yog 2,300º F (1,260º C).
Hauv cov ntsiab lus, perlite yog txhua yam-natural, muaj kev nyab xeeb ntxhia uas siv los ua rwb thaiv tsev hauv tsev.
