I-Perlite lilitye le-siliceous elenzeka ngokwendalo elisetyenziselwa ukufudumala kwezakhiwo.

Imveliso
I-United States yeyona mveliso inkulu kwihlabathi kwaye ithengisa i-perlite. Amanye amazwe aphambili avelisa i-perlite aquka iTshayina, iGrisi, iJapan, iHungary, iArmenia, i-Itali, iMexico, iiPhilippines kunye neTurkey. Usenokuyibona njengeengqalutye ezincinci ezimhlophe ezisetyenziswa ekufakeni umhlaba kwiimbiza ukuphucula umoya kunye nokugcinwa komswakama.

Emva kokuba imbiwe, i-perlite ifudunyezwa ukuya kuthi ga kwi-1,600° F (871° C), nto leyo ebangela ukuba amanzi ayo anyibilike aze adale amaqamza amancinci amaninzi achaza iimpawu zomzimba ezikhethekileyo zeminerali. Ukufakwa kwe-Perlite kwi-insulation kwenziwa ngendlela ye-granular kunye ne-powder, kodwa abanye abavelisi bayidibanisa ne-gypsum okanye ezinye izinto ukuze bayiguqule ibe yibhodi yokukhusela. Ukongeza ekusetyenzisweni kwayo njenge-insulator kwizakhiwo, i-perlite isetyenziselwa ukukhupha izixhobo ezishushu kakhulu, ezifana neendawo zokugcina ezibandayo kakhulu kunye neetanki ze-cryogenic, kunye nokusetyenziswa kokutya.

Iimpawu kunye nokuchongwa

Izinto zokukhusela ezifumaneka emakhaya zingenziwa nge-perlite ukuba zineempawu ezilandelayo:
umbala walo omhlophe njengekhephu ukuya kutsho kumhlophe ongwevu. Ilitye eliluhlaza liqala kumbala ongwevu okhanyayo ukuya kumnyama ocwebezelayo, kodwa uhlobo olwandisiweyo olufumaneka emakhaya lubonakala lula ngombala walo omhlophe;
ilula. I-perlite ekhulisiweyo ingenziwa ukuze ibe nobunzima obuziikhilogram ezimbini nge-cubic foot; kunye/okanye
ubungakanani bayo beenkozo bunokwahluka, kodwa ngokubanzi azikho ngaphezu kwe-¼-intshi ububanzi.

Ukusebenza kwePerlite njenge-Insulator

I-Perlite isetyenziswa kakhulu njenge-free-fill insulation, ingakumbi kulwakhiwo lwe-masonry, ngenxa yeempawu ezilandelayo ezenza ukuba ibe nomtsalane:
ityhefu ephantsi. Ngokutsho kwePerlite Institute, “Akukho ziphumo zovavanyo okanye ulwazi olubonisa ukuba iperlite ibeka nayiphi na ingozi empilweni.” Ezinye izinto zokukhusela, ezifana ne-asbestos, i-vermiculite (enokuba ne-asbestos), kunye ne-fiberglass ziyingozi ngakumbi;
ukungangeni kweekhemikhali, oko kuthetha ukuba akuyi kutshabalalisa imibhobho, imibhobho yombane okanye yonxibelelwano. I-Perlite ine-pH emalunga ne-7, efana namanzi acocekileyo;
ukuguquguquka. Njengesigqubuthelo esingenazimbobo kulwakhiwo lwezakhiwo zobumba, i-perlite ingagalelwa kwimingxuma yebhloko yekhonkrithi apho izalisa khona yonke imingxunya, ii-cores, iindawo zesamente kunye nemingxunya yeendlebe. Iminerali iya kuhambahamba kuyo nayiphi na imingxunya, ukungalingani okanye ukufakelwa okubonakalayo. Ixhasa ubunzima bayo kwaye ayiyi kuzinza okanye ivalwe; I-Perlite samente
izinga eliphezulu lomlilo. Ii-Underwriters Laboratories zifumanise ukuba udonga lwebhloko yekhonkrithi olunezinga leeyure ezimbini, oluziisentimitha ezi-8 (20.32-cm) luphuculwa lube ziiyure ezine xa ii-cores zizaliswe yi-perlite ephathwe nge-silicone;
ayiboli kwaye ayixhathisi iintsholongwane;
ukuncitshiswa kwesandi. I-Perlite loose-fill insulation inako ukuzalisa zonke iindawo ezingenanto, imigca ye-mortar kunye nemingxunya yeendlebe, ngaloo ndlela ivumela ukunciphisa ukudluliselwa kwesandi emoyeni kwiindonga. Ibhloko yokwakhiwa kwesandi ekhaphukhaphu, eyi-8-intshi (20-cm) ezaliswe yi-perlite ifikelela kudidi lokudluliselwa kwesandi lwama-51, idlula imigangatho yokudluliselwa kwesandi ye-HUD;
ayinyamezeli ukufuma, nto leyo eyenza ukuba ibe luncedo ekusetyenzisweni kwiindawo ezichatshazelwe ngamanzi okanye ukufuma, njengakwiikhompawundi zokulinganisa umgangatho kunye nokufakelwa kobushushu phantsi komgangatho; kunye
zonke zendalo. ISebe lezaMandla laseMelika likhuthaza i-perlite njengezinto zokwakha eziluhlaza.
Ezinye zezicelo eziqhelekileyo ze-perlite njenge-insulator kwizakhiwo ziquka:

kwiindonga zeeyunithi ezingenanto;
kwimingxunya ephakathi kweendonga zodonga;
phakathi kweendonga zangaphandle zokwakhiwa kwezakhiwo kunye noboya bangaphakathi;
ukufakelwa kwe-insulation phantsi komgangatho kunye nokulinganisa imigangatho emidala. Kule ndlela yokusebenza, ukufakelwa kwe-perlite kugalelwa kumphezulu womgangatho wokuqala, kukrwelwe kubunzulu obufanelekileyo, kugutyungelwe ngekhadibhodi ebotshelelweyo okanye iibhodi ezikhaphukhaphu, kunye nomaleko wephepha leoyile;
kwiithayile zophahla;
njengokuthintela umlilo ojikeleze iitshimini, iingcango, amagumbi kunye neesefu; kunye
ukuze kufakwe iidekhi eluphahleni.
Imida

Ngexabiso le-R eliyi-2.7, i-perlite ayisebenzi kakuhle kwezinye izithinteli-moya, ezifana ne-fiberglass, i-rockwool kunye ne-cellulose. Nangona kunjalo, idlula ezinye ezifana ne-vermiculite, iimveliso zomthi ezikhululekileyo, kunye nomququ.
I-Perlite ayivumelekanga xa isetyenziswa apho iya kuvezwa ngqo kumaqondo obushushu aqhubekayo angama-200° F.
I-Perlite akufuneki isetyenziswe kwiindawo zangaphandle ezihlala zichatshazelwa ngamanzi okanye ukufuma. Apho kulindeleke ukuba kudibane namanzi amaninzi okanye ukufuma, kuyacetyiswa ukuba iplasta yesamente yasePortland iphalethiswe.
Iiplasta zePerlite azikhuthazwa ngaphezu kweepaneli zokufudumeza ezikhazimlayo ngenxa yexabiso lazo lokukhusela.
Ubushushu obuphezulu obunokumelana ne-perlite yi-2,300º F (1,260º C).
Ngamafutshane, i-perlite yiminerali yendalo yonke, ekhuselekileyo esetyenziswa njenge-insulation kwizakhiwo.
