I-Perlite iyidwala le-silice elivela ngokwemvelo elisetshenziselwa ukuvikela ukushisa ezakhiweni.

Ukukhiqizwa
I-United States ingumkhiqizi omkhulu kanye nomthengi we-perlite emhlabeni. Amanye amazwe ahamba phambili akhiqiza i-perlite afaka phakathi i-China, i-Greece, i-Japan, i-Hungary, i-Armenia, i-Italy, i-Mexico, i-Philippines kanye ne-Turkey. Ungase uyibone njengetshe elincane elimhlophe elisetshenziswa ekufakeni inhlabathi ukuze kuthuthukiswe umoya kanye nokugcinwa komswakama.

Ngemva kokumbiwa, i-perlite ishiswa cishe ku-1,600° F (871° C), okubangela ukuthi okuqukethwe kwamanzi ayo kuhwamuke futhi kudale amabhamuza amancane amaningi achaza izakhiwo zomzimba eziyingqayizivele zale minerali. Ukufakwa kwe-Perlite kukhiqizwa ngesimo se-granular kanye nesimo se-powder, kodwa abanye abakhiqizi bayihlanganisa ne-gypsum noma ezinye izinto ukuze bayiguqule ibe ibhodi lokufakwa kwe-insulator. Ngaphezu kokusetshenziswa kwayo njengesivikelo ezakhiweni, i-perlite isetshenziselwa ukufakwa kwe-insulator kwemishini esezingeni eliphansi lokushisa, njengendawo yokugcina ebanda kakhulu kanye namathangi e-cryogenic, kanye nasezinhlelweni zokucubungula ukudla.

Izakhiwo Ezibonakalayo Nokuhlonza

Ukufakwa komoya oshisayo okutholakala emakhaya kungenziwa nge-perlite uma kunezimfanelo ezilandelayo:
umbala walo omhlophe njengeqhwa kuya kompunga-omhlophe. Idwala elingacwengekile lisukela kokumpunga okukhanyayo okubonakalayo kuya kokumnyama okucwebezelayo, kodwa isimo esinwetshiwe esitholakala emakhaya sibonakala kalula ngombala walo omhlophe;
ilula. I-perlite enwetshiwe ingakhiqizwa ukuze ibe nesisindo esingamakhilogremu amabili nge-cubic foot; kanye/noma
Ubukhulu bayo bokusanhlamvu bungahluka, kodwa ngokuvamile abudluli ku-¼-intshi ububanzi.

Ukusebenza kwePerlite njenge-Insulator

I-Perlite isetshenziswa kabanzi njengokuvikela ukungcola okukhululekile, ikakhulukazi ekwakhiweni kobumba, ngenxa yezimfanelo ezilandelayo ezenza ifiseleke:
ubuthi obuphansi. Ngokusho kwe-Perlite Institute, “Akukho mphumela wokuhlolwa noma ulwazi olubonisa ukuthi i-perlite ibeka noma iyiphi ingozi empilweni.” Ezinye izinto zokuvikela, njenge-asbestos, i-vermiculite (engase iqukathe i-asbestos), kanye ne-fiberglass ziyingozi kakhulu;
ukungasebenzi kahle kwamakhemikhali, okusho ukuthi ngeke kugqwale amapayipi, imigudu kagesi noma yokuxhumana. I-Perlite ine-pH ecishe ibe ngu-7, efana namanzi ahlanzekile;
ukuguquguquka. Njengesivikelo esingenazihibe ekwakheni ubumba, i-perlite ingathululelwa ezimbotsheni zebhulokhi likakhonkolo lapho igcwalisa khona ngokuphelele yonke imifantu, ama-cores, izindawo zodaka kanye nemigodi yezindlebe. Iminerali izogeleza izungeze noma yikuphi ukugoba, ukungalingani noma ukufakwa okuveziwe. Isekela isisindo sayo futhi ngeke ihlale noma ivale; usimende we-perlite
izinga eliphezulu lomlilo. I-Underwriters Laboratories ithole ukuthi udonga lwebhulokhi yekhonkrithi olulinganiselwa emahoreni amabili, oluyi-8 intshi (20.32-cm) luthuthukiswa lube amahora amane lapho ama-cores egcwaliswe nge-perlite ephathwe nge-silicone;
ukumelana nokubola kanye nezinambuzane;
ukuncishiswa komsindo. Ukufakwa komoya okukhululekile kwe-Perlite kunekhono lokugcwalisa zonke izikhala, imigqa ye-mortar kanye nezimbobo zezindlebe, okwenza kube lula ukunciphisa ukudluliswa komsindo emoyeni ngezindonga. Ibhulokhi elincane, elingamasentimitha angu-8 (20-cm) eligcwele i-perlite lifinyelela isigaba sokudlulisa umsindo esingu-51, sidlula amazinga okudlulisa umsindo we-HUD;
ukumelana nomswakama, okwenza kube wusizo ukusetshenziswa ezindaweni ezivezwe emanzini noma umswakama, njengasezintweni zokulinganisa phansi kanye nokuvikela ngaphansi kwephansi; kanye
konke kungokwemvelo. UMnyango Wezamandla wase-US ukhuthaza i-perlite njengezinto zokwakha eziluhlaza.
Ezinye izinhlelo zokusebenza ezivamile ze-perlite njengesivikelo sokuvikela ezakhiweni zifaka:

emaphethelweni ezindonga zeyunithi ezingenalutho;
ezimbotsheni eziphakathi kwezindonga zokhuni;
phakathi kwezindonga zokhuni zangaphandle kanye noboya bangaphakathi;
ukuze kufakwe uthango ngaphansi kwephansi kanye nokulinganisa phansi okudala. Kulesi sicelo, uthango lwe-perlite luthelwa ebusweni bephansi bokuqala, luhlikihlwe lujule ngendlela efanele, lumbozwe ngekhadibhodi eligoqiwe noma amabhodi alula, kanye nesendlalelo sephepha lamafutha;
kumathayili ophahleni;
njengokuvikela umlilo eduze kwamashimela, iminyango, amakamelo kanye nama-safe; kanye
uphahla oluphansi.
Ukulinganiselwa

Ngenani elingu-R elingu-2.7, i-perlite isebenza kancane kunezinye izivikeli, njenge-fiberglass, uboya be-rockwool kanye ne-cellulose. Nokho, isebenza kangcono kunezinye, njenge-vermiculite, imikhiqizo yokhuni ekhululekile, kanye notshani.
I-Perlite ayamukeleki ekusetshenzisweni lapho izovezwa ngqo emazingeni okushisa aqhubekayo angu-200° F.
I-Perlite akufanele isetshenziswe ezindaweni zangaphandle ezivame ukuchayeka emanzini noma emswakama. Lapho kulindeleke ukuthintana namanzi noma umswakama omningi, kunconywa i-plaster yesamente yasePortland.
Ama-plaster e-Perlite awanconywa ngaphezu kwamaphaneli okushisa akhanya kakhulu ngenxa yamanani awo okuvikela.
Izinga lokushisa eliphakeme kakhulu elingamelana ne-perlite lingu-2,300º F (1,260º C).
Ngamafuphi, i-perlite iyiminerali yemvelo nephephile esetshenziswa njengokuvikela izakhiwo.
