Perlite yog pob zeb siliceous uas tshwm sim ntuj tsim uas siv rau kev rwb thaiv tsev thermal hauv cov tsev.

Kev tsim khoom
Tebchaws Meskas yog lub tebchaws tsim thiab siv perlite loj tshaj plaws hauv ntiaj teb. Lwm lub tebchaws uas tsim perlite suav nrog Tuam Tshoj, Tim Nkij teb chaws, Nyiv Pooj, Hungary, Armenia, Ltalis, Mexico, Philippines, thiab Qaib Cov Txwv. Tej zaum koj yuav paub nws ua cov pob zeb me me dawb siv rau hauv cov av cog qoob loo kom txhim kho kev ua pa thiab khaws cov dej noo.

Tom qab nws raug khawb, perlite raug cua sov rau kwv yees li 1,600° F (871° C), uas ua rau nws cov dej hauv pa thiab tsim cov npuas me me uas ua rau cov khoom siv lub cev tshwj xeeb ntawm cov pob zeb. Kev rwb thaiv tsev Perlite yog tsim tawm hauv daim ntawv granular nrog rau daim ntawv hmoov, tab sis qee cov chaw tsim khoom sib xyaw nws nrog gypsum lossis lwm yam khoom siv los hloov nws mus rau hauv lub rooj tsavxwm rwb thaiv tsev. Ntxiv rau nws siv ua lub rwb thaiv tsev hauv tsev, perlite yog siv rau kev rwb thaiv tsev ntawm cov khoom siv kub qis, xws li super-cold cia thiab cryogenic tanks, nrog rau hauv cov ntawv thov ua zaub mov.

Cov Khoom Siv Lub Cev thiab Kev Txheeb Xyuas

Cov khoom rwb thaiv tsev uas pom muaj nyob hauv tsev yuav ua los ntawm perlite yog tias nws muaj cov yam ntxwv hauv qab no:
nws cov xim dawb li daus mus rau xim greyish-dawb. Cov pob zeb nyoos yog los ntawm xim grey pob tshab mus rau xim dub ci, tab sis cov qauv nthuav dav uas pom hauv tsev yooj yim txheeb xyuas los ntawm nws cov xim dawb;
nws tsis hnyav heev. Cov perlite uas nthuav dav tuaj yeem tsim tau kom hnyav li 2 phaus ib cubic foot; thiab/lossis
nws cov noob qoob loo yuav txawv, tab sis feem ntau lawv tsis loj dua ¼-nti hauv txoj kab uas hla.

Perlite Kev Ua Haujlwm Ua Ib Lub Insulator

Perlite yog siv dav ua cov rwb thaiv tsev xoob, tshwj xeeb tshaj yog hauv kev tsim kho masonry, vim yog cov yam ntxwv hauv qab no uas ua rau nws xav tau:
tsis muaj tshuaj lom. Raws li Perlite Institute, "Tsis muaj qhov tshwm sim lossis cov ntaub ntawv qhia tias perlite muaj kev pheej hmoo rau kev noj qab haus huv." Lwm cov khoom rwb thaiv tsev, xws li asbestos, vermiculite (uas yuav muaj asbestos), thiab fiberglass muaj kev phom sij ntau dua;
tsis muaj tshuaj lom neeg nyob hauv, txhais tau tias nws yuav tsis ua rau cov kav dej, cov hluav taws xob lossis cov kav dej sib txuas lus xeb. Perlite muaj pH li ntawm 7, uas zoo ib yam li dej tshiab;
kev ywj pheej. Raws li cov khoom siv rwb thaiv tsev hauv kev tsim kho masonry, perlite tuaj yeem nchuav rau hauv cov qhov ntawm cov pob zeb ua vaj tse uas nws puv tag nrho cov qhov tawg, cov qhov tseem ceeb, cov chaw mortar thiab cov qhov pob ntseg. Cov mineral yuav ntws ncig txhua qhov roughness, tsis sib npaug lossis cov chaw teeb tsa. Nws txhawb nqa nws tus kheej qhov hnyav thiab yuav tsis sib haum lossis txuas; Perlite cement
qib hluav taws kub siab. Underwriters Laboratories tau pom tias phab ntsa pob zeb uas ntsuas tau ob teev, 8-nti (20.32-cm) tau zoo dua mus rau plaub teev thaum cov tub ntxhais raug ntim nrog silicone-treated perlite;
tiv taus kev lwj thiab kab tsuag;
kev txo suab nrov. Perlite loose-fill insulation muaj peev xwm sau tag nrho cov qhov khoob, cov kab mortar thiab cov qhov pob ntseg, yog li ua rau nws txo tau cov suab kis los ntawm huab cua los ntawm phab ntsa. Lub pob zeb masonry sib dua, 8-nti (20-cm) puv nrog perlite ua tiav qib kis suab ntawm 51, dhau HUD cov qauv kis suab;
tsis kam dej noo, ua rau nws muaj txiaj ntsig zoo rau kev siv rau hauv cov cheeb tsam uas raug dej lossis av noo, xws li hauv cov khoom sib xyaw ua ke hauv pem teb thiab cov khoom rwb thaiv tsev hauv qab pem teb; thiab
txhua yam ntuj tsim. Lub Tsev Haujlwm Saib Xyuas Zog ntawm Tebchaws Meskas txhawb nqa perlite ua cov khoom siv hauv tsev ntsuab.
Qee cov ntawv thov siv rau perlite ua cov khoom rwb thaiv tsev hauv cov tsev suav nrog:

nyob rau hauv cov core ntawm cov phab ntsa hollow-masonry unit;
nyob rau hauv cov qhov ntawm cov phab ntsa masonry;
nruab nrab ntawm cov phab ntsa masonry sab nraud thiab cov furning sab hauv;
rau kev rwb thaiv tsev hauv qab pem teb thiab kev ua kom cov plag tsev qub tiaj tus. Hauv daim ntawv thov no, perlite rwb thaiv tsev raug nchuav rau ntawm qhov chaw hauv pem teb qub, screed kom tob txaus, npog nrog corrugated cardboard lossis lightweight boards, thiab ib txheej ntawm cov ntawv roj;
hauv cov vuas vov tsev;
ua kev tiv thaiv hluav taws nyob ib puag ncig cov qhov cub, qhov rooj, chav thiab cov chaw nyab xeeb; thiab
rau kev ua kom lub ru tsev.
Cov kev txwv

Yog tias tus nqi R ntawm 2.7, perlite ua haujlwm tsis zoo dua lwm cov khoom rwb thaiv tsev, xws li fiberglass, rockwool thiab cellulose. Txawm li cas los xij, nws ua haujlwm zoo dua lwm cov khoom xws li vermiculite, cov khoom ntoo uas tsis muaj qhov seem, thiab straw.
Perlite tsis raug lees txais rau cov ntawv thov uas nws yuav raug ncaj qha rau qhov kub thiab txias tas mus li ntawm 200 ° F.
Tsis txhob siv perlite rau ntawm cov chaw sab nraud uas raug dej lossis dej noo ntau dhau. Yog tias xav tias yuav raug dej lossis dej noo ntau dhau, cov cement Portland cement yog qhov zoo.
Tsis pom zoo kom siv cov perlite plasters hla cov vaj huam sib luag cua sov vim lawv cov nqi rwb thaiv tsev.
Qhov kub siab tshaj plaws uas perlite tuaj yeem tiv taus yog 2,300º F (1,260º C).
Hauv kev xaus lus, perlite yog cov khoom siv ntuj tsim, muaj kev nyab xeeb uas siv los ua rwb thaiv tsev hauv cov tsev.
