I-Perliteiyidwala le-siliceous elenzeka ngokwemvelo elisetshenziselwa ukwahlukanisa okushisayo ezakhiweni.

Ukukhiqiza
I-United States ingumkhiqizi nomthengi omkhulu we-perlite emhlabeni. Amanye amazwe ahamba phambili akhiqiza i-perlite ahlanganisa iChina, Greece, Japan, Hungary, Armenia, Italy, Mexico, Philippines, kanye neTurkey. Ungase ukubone njengamatshe amancanyana amhlophe asetshenziswa ekubumbeni inhlabathi ukuze kuthuthukiswe ukungena komoya kanye nokugcina umswakama.

Ngemva kokumbiwa, i-perlite ishisisa ifike ku-1,600° F (871° C), okubangela ukuthi amanzi ayo ahwamuke futhi adale inqwaba yamabhamuza amancane abangela izici eziyingqayizivele zemvelo zale mineral. Ukufakwa kwe-Perlite kukhiqizwa ngendlela ye-granular kanye nefomu lempushana, kodwa abanye abakhiqizi bahlanganisa ne-gypsum noma ezinye izinto zokuyiguqula ibe ibhodi lokuvikela. Ngaphezu kokusetshenziswa kwayo njenge-insulator ezakhiweni, i-perlite isetshenziselwa ukufakwa kwemishini yokushisa ephansi, njengesitoreji esibanda kakhulu kanye namathangi e-cryogenic, kanye nezinhlelo zokusebenza zokucubungula ukudla.

Izakhiwo Zomzimba kanye Nokuhlonza

I-insulation etholakala ezindlini ingenziwa nge-perlite uma inalezi zimfanelo ezilandelayo:
okumhlophe qhwa kuya kokumpunga-mhlophe ngombala. Itshe elingahluziwe lisukela kokumpunga okukhanyayo kuya kokumnyama okucwebezelayo, kodwa uhlobo olunwetshiwe olutholakala ezindlini lubonakala kalula ngombala walo omhlophe;
ilula. I-perlite enwetshiwe ingakhiqizwa ibe nesisindo esingamakhilogremu angu-2 nge-cubic foot ngayinye; kanye/noma
osayizi bayo bokusanhlamvu bangase bahluke, kodwa ngokuvamile abakhudlwana kuno-¼-intshi ngobubanzi.

Ukusebenza kwePerlite njenge-Insulator

I-Perlite isetshenziswa kabanzi njenge-loose-fill insulation, ikakhulukazi ekwakhiweni kwamatshe, ngenxa yezimfanelo ezilandelayo ezenza ifiseleke:
ubuthi obuphansi. Ngokusho kwe-Perlite Institute, "Awukho umphumela wokuhlolwa noma ulwazi olubonisa ukuthi i-perlite ibeka noma iyiphi ingozi yezempilo." Amanye ama-insulators, njenge-asbestos, i-vermiculite (engase ibe ne-asbestos), ne-fiberglass ayingozi kakhulu;
ukungabi namandla kwamakhemikhali, okusho ukuthi ngeke kugqwese amapayipi, amapayipi kagesi noma okuxhumana. I-Perlite ine-pH ezungeze u-7, efana namanzi ahlanzekile;
ukuphenduleka. Njengesivikelo sokugcwalisa okuxekethile ekwakhiweni kwamatshe, i-perlite ingathululelwa emigodini yebhulokhi likakhonkolo lapho igcwalisa ngokuphelele yonke imifantu, ama-cores, izindawo zodaka kanye nezimbobo zezindlebe. I-mineral izogeleza eduze kwanoma yibuphi ubulukhuni, ukungalingani noma ukufakwa obala. Isekela isisindo sayo futhi ngeke ixazulule noma ibhuloho; usimende wePerlite
izinga eliphezulu lomlilo. I-Underwriters Laboratories ithole ukuthi udonga lwebhulokhi lukakhonkolo olulinganiswe amahora amabili, olulinganiswe ngamasentimitha angu-8 (20.32-cm) luthuthukiswa lube amahora amane lapho ama-cores egcwele i-perlite ephekwe nge-silicone;
ukubola kanye nokumelana nezilokazane;
ukuncishiswa komsindo. I-Perlite loose-fill insulation inamandla okugcwalisa wonke ama-void, imigqa yodaka kanye nezimbobo zezindlebe, ngaleyo ndlela ikwazi ukunciphisa ukudluliswa komsindo ophuma emoyeni ngokusebenzisa izindonga. I-Lightweight, 8-intshi (20-cm) ibhulokhi lamatshe eligcwele i-perlite ifinyelela isigaba sokudlulisa umsindo esingu-51, esidlula izindinganiso zokudlulisa umsindo ze-HUD;
ukumelana nomswakama, okwenza kube usizo ekusetshenzisweni ezindaweni ezichayeke emanzini noma ezimanzi, njengezinhlanganisela zokulinganisa phansi kanye nokufakwa ngaphansi kwaphansi; futhi
konke okungokwemvelo. UMnyango Wezamandla wase-US ukhuthaza i-perlite njengento yokwakha eluhlaza.
Ezinye izinhlelo zokusebenza ezijwayelekile ze-perlite njenge-insulator ezakhiweni zifaka:

ezingxenyeni zezindonga zeyunithi ye-hollow-masonry;
emigodini ephakathi kwezindonga zamatshe;
phakathi kwezindonga zamatshe zangaphandle kanye noboya bangaphakathi;
ukuze kufakwe i-under-floor insulation kanye nokulinganisa kwamaphansi amadala. Kulolu hlelo lokusebenza, ukufakwa kwe-perlite kuthululelwa endaweni yokuqala yaphansi, i-screeded ekujuleni okufanele, embozwe ngekhadibhodi likathayela noma amabhodi angasindi, kanye nongqimba lwephepha lamafutha;
ku-ceiling tile;
njengokuvikela umlilo nxazonke koshimula, iminyango, amagumbi nezisefo; futhi
yokuhlobisa uphahla.
Ukulinganiselwa

Ngevelu engu-R engu-2.7, i-perlite yenza ngaphansi kwezinye izivikeli, njenge-fiberglass, i-rockwool ne-cellulose. Idlula ezinye, nokho, njenge-vermiculite, imikhiqizo yokhuni engagcwali kahle, notshani.
I-Perlite ayamukelekile ezinhlelweni zokusebenza lapho izovezwa khona ngokuqondile emazingeni okushisa aqhubekayo angu-200° F.
I-Perlite akufanele isetshenziswe ezindaweni zangaphandle ezivame ukuchayeka emanzini noma kumswakama. Lapho ukuthintana namanzi amaningi noma umswakama kulindeleke, i-Portland usimende plaster iyanconywa.
Ama-perlite plasters awanconywa phezu kwamaphaneli okushisa akhazimulayo ngenxa yamanani awo okuvikela.
Izinga lokushisa eliphezulu elingamelana ne-perlite ngu-2,300º F (1,260º C).
Kafushane, i-perlite iyimaminerali engokwemvelo, ephephile esetshenziswa njenge-insulation ezakhiweni.
