Perlitelilitye le-siliceous elenzeka ngokwendalo elisetyenziselwa ukugquma ubushushu kwizakhiwo.

Imveliso
I-United States ngowona mvelisi mkhulu wehlabathi kunye nomthengi weperlite. Amanye amazwe aphambili avelisa i-perlite aquka iChina, iGrisi, iJapan, iHungary, iArmenia, iItali, iMexico, iiPhilippines, neTurkey. Usenokuyiqonda njengengqalutye emhlophe esetyenziswa ekugaleni umhlaba ukuze kungene umoya nokugcina ukufuma.

Emva kokuba yombiwe, i-perlite ifudunyezwa malunga ne-1,600 ° F (871 ° C), nto leyo ibangela ukuba amanzi ayo abe ngumphunga kwaye enze amaqamza amancinci abangela iimpawu ezizodwa zeminerali. I-Perlite insulation iveliswa kwifomu yegranular kunye nefom ye powder, kodwa abanye abavelisi badibanisa ne-gypsum okanye ezinye izinto zokuyijika zibe yibhodi yokukhusela. Ukongeza ekusebenziseni kwayo njenge-insulator kwizakhiwo, i-perlite isetyenziselwa ukufakwa kwezixhobo zokushisa okuphantsi, ezifana nokugcinwa okubanda kakhulu kunye neetanki ze-cryogenic, kunye nezicelo zokulungisa ukutya.

IiPropati zoMzimba kunye nokuchongwa

I-Insulation efumaneka kumakhaya inokwenziwa nge-perlite ukuba inezi mpawu zilandelayo:
ikhephu elimhlophe ukuya kungwevu-mhlophe ngombala. Uluhlu lwamatye akrwada ukusuka kukukhanya okungwevu okucacileyo ukuya kumnyama omenyezelayo, kodwa uhlobo olwandisiweyo olufumaneka ezindlini luchongwa lula ngombala walo omhlophe;
ilula. I-perlite eyandisiweyo inokuveliswa ukuba inobunzima obuncinane njenge-2 pounds nge-cubic foot; kunye/okanye
ubungakanani beenkozo zayo zinokwahluka, kodwa ngokubanzi azikho nkulu kune ¼-intshi ngobubanzi.

Ukusebenza kwePerlite njenge-Insulator

I-Perlite isetyenziswa ngokubanzi njenge-insulation-fill-loose-fill, ngakumbi kulwakhiwo lwama-masonry, ngenxa yezi mpawu zilandelayo ezenza ukuba inqweneleke:
ubuthi obuphantsi. Ngokutsho kwePerlite Institute, "Akukho ziphumo zovavanyo okanye ulwazi olubonisa ukuba i-perlite ibeka nayiphi na ingozi kwimpilo." Ezinye ii-insulators, ezifana ne-asbestos, i-vermiculite (enokuthi iqulethe i-asbestos), kunye ne-fiberglass ziyingozi kakhulu;
ukungazinzi kweekhemikhali, okuthetha ukuba ayizukonakalisa imibhobho, imibhobho yombane okanye yonxibelelwano. I-Perlite ine-pH ejikeleze i-7, efana namanzi ahlambulukileyo;
ukuthobela. Njenge-insulator ekhululekileyo ekwakhiweni kwe-masonry, i-perlite inokugalelwa kwimingxuma yebhloko yekhonkrithi apho igcwalisa ngokupheleleyo yonke imingxuma, ii-cores, iindawo zodaka kunye nemingxuma yeendlebe. Iminerali iya kuhamba malunga nabuphi na uburhabaxa, ukungalingani okanye ufakelo oluvezwayo. Ixhasa ubunzima bayo kwaye ayiyi kuhlala okanye ibhulorho;Isamente yePerlite
izinga eliphezulu lomlilo. I-Underwriters Laboratories ifumene ukuba udonga lwebhloko ye-concrete ye-8-intshi (20.32 cm) luphuculwe kwiiyure ezine xa iinqununu zizaliswe nge-silicone-treated perlite;
ukubola- kunye nokumelana nezinambuzane;
ukunciphisa isandi. I-Perlite i-loose-fill insulation inamandla okuzalisa zonke i-voids, imigca yodaka kunye nemingxuma yeendlebe, ngaloo ndlela ivumela ukunciphisa ukuhanjiswa kwesandi esiphuma emoyeni ngeendonga. I-Lightweight, i-8-intshi (i-20-cm) ibhloko ye-masonry ezaliswe nge-perlite ifezekisa iklasi yokudlulisa isandi se-51, idlula imigangatho yokudlulisa isandi se-HUD;
ukumelana nokufuma, okwenza kube luncedo ekusetyenzisweni kwiindawo ezivuleleke kumanzi okanye kumanzi, njengakwikhompawundi zomgangatho womgangatho kunye nokugqunyelelwa ngaphantsi komgangatho; kwaye
zonke zendalo. ISebe lezaMandla lase-US lixhasa i-perlite njengesixhobo sokwakha esiluhlaza.
Ezinye izicelo eziqhelekileyo ze-perlite njenge-insulator kwizakhiwo ziquka:

kwiindonga zeendonga zeyunithi ye-hollow-masonry;
kwimingxuma phakathi kweendonga zamatye;
phakathi kweendonga zangaphandle kunye ne-furring yangaphakathi;
ukwenzela ukugquma phantsi komgangatho kunye nokulinganisa imigangatho emidala. Kule sicelo, i-perlite insulation igalelwa kumgangatho wokuqala womgangatho, i-screeded ukuya kubunzulu obufanelekileyo, ehlanganiswe ngekhadibhodi edibeneyo okanye iibhodi ezilula, kunye noluhlu lwephepha leoli;
kwiithayile zesilingi;
njengokuthintela umlilo kwitshimini, iingcango, amagumbi kunye neesefu; kwaye
yokuhombisa uphahla.
Ukulinganiselwa

Ngexabiso le-R le-2.7, i-perlite ingaphantsi kwe-insulators, njenge-fiberglass, i-rockwool kunye ne-cellulose. Iyazigqwesa ezinye, nangona kunjalo, ezifana nevermiculite, iimveliso zokhuni ezikhululekileyo, kunye neendiza.
IPerlite ayamkelekanga kwizicelo apho iya kuboniswa ngokuthe ngqo kumaqondo obushushu aqhubekayo angama-200° F.
I-Perlite ayifanele isetyenziswe kwiindawo zangaphandle ezihlala zibonakaliswe kumanzi okanye ukufuma. Apho ukudibana namanzi amaninzi okanye ukufuma kulindeleke, udaka lwesamente ePortland luyacetyiswa.
I-Perlite plasters ayikhuthazwa phezu kweepaneli zokufudumeza ezikhanyayo ngenxa yexabiso labo lokukhusela.
Obona bushushu buphezulu obunokumelana neperlite yi-2,300º F (1,260º C).
Isishwankathelo, i-perlite yinto yonke-yendalo, iminerali ekhuselekileyo esetyenziswa njenge-insulation kwizakhiwo.
