I-perlite enwetshiwe iyona elula kunazo zonke izinhlanganisela zamaminerali ezifanele ukhonkolo. Ikhonkolo evikela ukushisa futhi elula, ehlanganisa i-perlite isetshenziselwa izinqubo ezahlukahlukene zokwakha kanye nemikhiqizo yezimboni—kufaka phakathi amadekhi ophahleni, izingqimba zeshimini, izithombe, amatshe okuhlobisa, izimbotshana zamathayela, izingodo zomlilo zegesi, izinhlelo zaphansi kanye nokugcwalisa, amathangi okugcina uphethiloli, izisekelo zamathangi okuvikela ukushisa kanye namachibi okubhukuda, kanye nokukhulisa izimfanelo zomsindo kanye nokumelana nomlilo ezindongeni, phansi kanye nensimbi yesakhiwo.
I-Perlite Ukhonkolo
Uma isetshenziswa njenge-aggregate eyinhloko kukhonkolo, i-perlite enwetshiwe inikeza izinzuzo eziningana ezibalulekile ekusetshenzisweni kokwakhiwa kanye nokwakhiwa kwangaphambilini. Nakuba ikhonkolo ye-perlite elula ingavamile ukufanela ukusetshenziswa kwesakhiwo noma ukuthwala umthwalo, kwezinye izinhlelo zokusebenza inikeza ukuthuthukiswa kokucindezeleka komthwalo, ukunciphisa umsindo, ukumelana nokudluliselwa kokushisa, kanye nesilinganiso somlilo.
Ngokuvamile, ukhonkolo we-perlite ungahlukaniswa ngezigaba ezimbili—okhanyayo kakhulu nolula. Ukhonkolo we-perlite okhanyayo kakhulu unobuningi obungaphansi kwama-50 lbs/ft3 (800 kg/m3) futhi usetshenziselwa kakhulu amadekhi ophahleni, imibhede yokutshala ephakanyisiwe, izindonga zamakhethini, kanye nezicelo zokushisa unomphela njengamathangi okugcina igesi yemvelo encibilikisiwe (LNG). Ukhonkolo we-perlite okhanyayo unobuningi obuphakathi kwama-50 kuya ku-110 lb/ft3 (800 - 1800 kg/m3), uhlanganisa isihlabathi se-microsilica, futhi unikeza amandla aphezulu okucindezela nokuguquguquka, okwenza kube sezingeni elifanele lokuqeda phansi nokugcwalisa. Kuzo zombili izinhlobo, ukusetshenziswa kwe-ejenti yokufaka umoya kuthuthukisa ukusebenza kahle, kunikeza ukulawulwa kokuqina, futhi kugcina inani lokushisa.
I-Perlite ku-Well Cement
Ikhono le-Perlite lokusingatha ukushisa linikeza izinto zokwakha ukhonkolo ezilula eziphumelelayo ezingalahlekelwa kakhulu ngenxa yekhono lazo lokuvala izikhala nokuvala ama-fracture. Ezinye izinzuzo zifaka phakathi isivuno esikhulu ngobuningi obulula, izimfanelo zokuvikela, izici ezinhle kakhulu zokulahlekelwa uketshezi, kanye nengcindezi ephansi ye-hydrostatic ezimweni ezizungezile.
Ikhonkrithi Yokufaka Ukushisa E-Perlite Yama-Roof Decks
Izinhlelo zokuvikela ezivamile eziqinile ziyinkimbinkimbi futhi kunzima ukuzifaka futhi zingalahlekelwa yi-30% yamanani azo okuvikela ashicilelwe ngenxa yokuncipha komkhiqizo, ukukhukhuleka kokushisa, kanye nokubopha ukushisa phezu kwedekhi yensimbi ngokusebenzisa izinamathiselo zemishini. Azikho izinkinga ezinjalo ngamadekhi ophahla lwekhonkrithi e-perlite. Amadekhi ophahla lwekhonkrithi e-Perlite awanamthungo, ahlinzeka ngesisekelo esibushelelezi, esilinganayo se-monolithic se-membranes yophahla enamathele ngqo. Ikhonkrithi ye-Perlite ingafakwa phezu kwedekhi yensimbi ehlanganisiwe, ikhonkrithi ehlanganisiwe noma ethelwe endaweni, noma ngisho nangaphezu kwezinto zokuphahla ezikhona ezizwakalayo.
Ikhonkrithi ye-Perlite iyisisekelo esifanele sezinhlelo zokufulela ezakhiwe kanye nezine-ply eyodwa. Inamandla okumelana nomoya nomlilo, futhi, ngokufakwa kwe-polystyrene insulation ehlanganiswe kukhonkrithi ye-perlite, amazinga aphezulu okumelana nokushisa afinyelelwa ngokomnotho. Umphumela: idekhi yophahla eqinile ngendlela emangalisayo ezovikela futhi imelane nomlilo impilo yonke yesakhiwo. Ukuphinda ufulele kuyindaba nje yokushintsha i-membrane.
Izinhlobo zengxube yekhonkrithi ye-Perlite zingaklanywa ngobuningi obusukela ku-20 kuya ku-50 lbs/ft3, okusho ukuthi uhlelo lwedekhi lophahla lwekhonkrithi ye-perlite olunesilinganiso se-R-30 lungafika ngaphansi kwama-8 lbs. ngefidi lesikwele.
Ezinye izinto okufanele uzicabangele: izinhlelo zophahla lwekhonkrithi ye-perlite zithambekele kalula ukuze zikhiphe amanzi; kungenzeka ukuthi kusetshenziswe izilinganiso zomlilo kusukela ehoreni eli-1 kuya kwele-3; ikhonkrithi ye-perlite elula ingapompiwa, ithululwe, noma iplastwe endaweni yayo; ikhonkrithi ye-perlite elungisiwe ingabethelwa, isahwe, futhi isetshenzwe ngamathuluzi ajwayelekile.
Ukuhlolwa Nokuvunyelwa. Izinhlelo zokuvikela uphahla lwekhonkrithi ye-Perlite zihlolwe futhi zavunyelwa ukuthola izilinganiso zomoya nomlilo yi-Underwriters Laboratories, i-Factory Mutual, kanye nezinye iziphathimandla zekhodi. Ama-deck ophahla lwekhonkrithi ye-Perlite anebhodi lokuvikela i-polystyrene ahlangabezana nezindinganiso zokumelana nomoya ze-UL Class 90 kanye ne-FM 1-90.
Imikhiqizo Yamatshe Okuhlobisa Eyenziwe
Inzuzo enkulu yokusebenzisa i-perlite aggregate enwetshiwe emikhiqizweni eyenziwe ngamatshe nezitini ukonga isisindo—isisindo esifinyelela kwesithathu kunemiklamo evamile yokuxuba. Lokho konga isisindo kunezinzuzo ezicacile: isakhiwo sokusekela esingenaso ukuqina (njengezinsika kanye nezinyawo) ze-veneer, kanye nokonga izindleko ekuphatheni nasekuthumeleni.
Izakhiwo zekhonkrithi ye-Perlite ezivikela ukushisa kanye nokumelana nomlilo nazo zengeza inani emikhiqizweni yamatshe akhuliswe kahle, zinegalelo ngqo ekulinganisweni kokudlulisa ukushisa kwesakhiwo.
Ngokuvamile, imiklamo exubile yemikhiqizo yamatshe akhuliswe nge-perlite isukela ku-1:4 (i-binder: i-perlite) kuya ku-1:20 ngevolumu.
Izisekelo Zethangi Lokugcina Izinto Ezivikela Ukushisa kanye Nechibi Lokubhukuda
Izakhiwo zokuvikela umswakama zekhonkrithi ye-Perlite ziyasebenza ngempela uma zisetshenziswa ukwakha isisekelo samatangi okugcina angadlulisi ukushisa kanye namachibi okubhukuda e-vinyl angaphansi komhlaba. Ngokukhethekile emachibini okubhukuda angaphansi komhlaba, ukulahlekelwa ukushisa emhlabathini kuncishiswa kakhulu, ngaleyo ndlela kuhlinzeke ngokushisa okulinganayo kwamanzi echibini kanye nokunciphisa umthwalo emishinini yokushisa. Ukusebenza kahle kwesisekelo sekhonkrithi ye-perlite kunikeza isisekelo esiqinile nesingenamthungo sama-liner echibini le-vinyl—futhi kuyisihluthulelo sokuphila isikhathi eside kwama-liner.
Izilinganiso zokwakheka kwengxube ezijwayelekile zisukela ku-1:5 (i-binder:perlite) kuya ku-1:8, kanti izilinganiso eziphakeme ze-perlite zinikeza ukumelana okukhulu kokushisa. Ubukhulu obuncane besisekelo obungamasentimitha amabili (5cm) buyadingeka ukuze kufezwe amandla nezinzuzo zokuvimbela ukushisa.
