I-perlite eyandisiweyo yeyona ilula kuzo zonke iiminerali ezidityanisiweyo ezifanelekileyo kwikhonkrithi. Ikhonkrithi egqumayo nekhaphukhaphu, e-perlite-aggregate isetyenziselwa iinkqubo ezahlukeneyo zokwakha kunye neemveliso zoshishino—kuquka iidekhi zophahla, ii-linings zetshimini, imifanekiso eqingqiweyo, amatye okuhombisa, ii-tile mortars, iinkuni zomlilo zegesi, iinkqubo zomgangatho kunye nokuzaliswa, iitanki zokugcina amafutha, iitanki zokukhusela kunye neziseko zedama lokubhukuda, kunye nokwandisa isandi kunye nokumelana nomlilo kwiindonga, imigangatho kunye nentsimbi yesakhiwo.
I-Perlite Ikhonkrithi
Xa isetyenziswa njengesixhobo esiphambili kwikhonkrithi, i-perlite ekhulisiweyo inika iingenelo ezininzi ezibalulekileyo kwizicelo zokwakha kunye nokuveliswa kwangaphambili. Nangona ikhonkrithi ye-perlite ekhaphukhaphu ingaqhelekanga ukusetyenziswa kwizakhiwo okanye ekuthwaleni umthwalo, kwezinye iinkqubo inika uphuculo kuxinzelelo lomthwalo, ukunciphisa ingxolo, ukumelana nobushushu, kunye nomlinganiselo womlilo.
Ngokubanzi, ikhonkrithi ye-perlite ingahlulwahlulwa ibe ziindidi ezimbini—eyi-Ultralight kunye neyi-Lightweight. Ikhonkrithi ye-perlite ekhanyayo inobunzima obungaphantsi kwe-50 lbs/ft3 (800 kg/m3) kwaye isetyenziselwa ikakhulu iidekhi zophahla, iibhedi zokutyala eziphakamileyo, iindonga zekhethini, kunye nokusetyenziswa kobushushu obuhlala buhleli njengeetanki zokugcina igesi yendalo emanzi (LNG). Ikhonkrithi ye-perlite ekhanyayo inobunzima obuphakathi kwe-50 ukuya kwi-110 lb/ft3 (800 – 1800 kg/m3), ibandakanya isanti ye-microsilica, kwaye inika amandla aphezulu okuxinzelela kunye nokugoba, okwenza ukuba ifaneleke ukugqitywa komgangatho kunye nokuzalisa. Kuzo zombini ezi ntlobo, ukusetyenziswa kwearhente yokungenisa umoya kuphucula ukusebenza kakuhle, kubonelela ngolawulo loxinano, kwaye kugcina ixabiso lobushushu.
IPerlite kwiWell Cements
Amandla ePerlite okusingatha ubushushu abonelela ngezinto ezikhaphukhaphu ezisebenzayo nezilula ezingalahlekanga kangako ngenxa yokukwazi kwayo ukuvala iindawo ezingenanto kunye nokuvalela amaqhekeza. Ezinye iingenelo ziquka isivuno esikhulu xa ixinene kancinci, iimpawu zokukhusela, iimpawu zokulahleka kolwelo oluhle, kunye noxinzelelo oluphantsi lwe-hydrostatic kwiindawo ezingqongileyo.
Ikhonkrithi yokukhusela iPerlite kwiidekhi zophahla
Iinkqubo zokugquma eziqinileyo ziyinkimbinkimbi kwaye kunzima ukuzifakela kwaye zinokulahlekelwa yi-30% yamaxabiso azo okugquma ashicilelweyo ngenxa yokuncipha kwemveliso, ukushukuma kobushushu, kunye nokubopha ubushushu phezu kwedekhi yentsimbi ngokusebenzisa izibophelelo zoomatshini. Akukho ngxaki ezinjalo ngeedekhi zophahla zekhonkrithi zeperlite. Iidekhi zophahla zekhonkrithi zePerlite azinamthungo, zibonelela ngesiseko esigudileyo, esilinganayo se-monolithic see-membranes zophahla ezinamathele ngqo. Ikhonkrithi yePerlite ingabekwa phezu kwedekhi yentsimbi egobileyo, ikhonkrithi ebekwe kwangaphambili okanye ethululiweyo, okanye naphezu kwezinto zokugquma ezikhoyo eziqinileyo.
Ikhonkrithi yePerlite sisiseko esifanelekileyo kwiinkqubo zokufulela ezakhiweyo nezine-ply enye. Inokumelana okuphezulu komoya nomlilo, kwaye, ngokongezwa kwe-polystyrene insulation efakwe kwikhonkrithi yePerlite, amaxabiso aphezulu okumelana nobushushu afezekiswa ngokoqoqosho. Isiphumo: idekhi yophahla eqinileyo kakhulu eya kukhusela kwaye imelane nomlilo ubomi bonke besakhiwo. Ukuphinda ufulele ngumbandela wokutshintsha i-membrane.
Iifomyula zomxube wekhonkrithi yePerlite zinokuyilwa ngobuninzi obuphakathi kwe-20 ukuya kwi-50 lbs/ft3, oko kuthetha ukuba inkqubo yedekhi yophahla lwekhonkrithi yePerlite enereyithingi ye-R-30 inokuba ngaphantsi kwe-8 lbs. nge-square foot.
Ezinye izinto ekufuneka ziqwalaselwe: iinkqubo zophahla lwekhonkrithi yeperlite zithambekele ngokulula ukuze zitsalwe amanzi; umlinganiselo womlilo oqala kwiyure e-1 ukuya kweye-3 unokwenzeka; ikhonkrithi yeperlite ekhaphukhaphu ingapompelwa, igalelwe, okanye iplastwe endaweni yayo; ikhonkrithi yeperlite ecociweyo ingabethelwa, isarwe, kwaye isetyenziswe ngezixhobo eziqhelekileyo.
Uvavanyo kunye nokuVunywa. Iinkqubo zokukhusela uphahla lwekhonkrithi yePerlite zivavanyiwe kwaye zavunywa ukuze ziqwalaselwe umoya nomlilo yi-Underwriters Laboratories, iFactory Mutual, kunye nezinye iziphathamandla zekhowudi. Iidekhi zophahla lwekhonkrithi yePerlite ezinebhodi yokukhusela i-polystyrene ziyahlangabezana nemigangatho yokumelana nomoya ye-UL Class 90 kunye ne-FM 1-90.
Iimveliso zelitye lokuhombisa ezenziweyo
Eyona nzuzo ibalaseleyo yokusebenzisa i-expanded perlite aggregate kwiimveliso ze-veneer ezenziwe ngamatye nezitena kukugcina ubunzima—ubunzima obungaphezulu kwesinye kwisithathu kunoyilo oluqhelekileyo lomxube. Oko kugcina ubunzima kuneenzuzo ezicacileyo: ulwakhiwo olungenabugocigoci benkxaso (ezifana nee-ledges kunye ne-footings) ze-veneer, kunye nokonga iindleko ekuphatheni nasekuthumeleni.
Iimpawu zokukhusela nokumelana nomlilo zekhonkrithi yePerlite nazo zongeza ixabiso kwiimveliso zamatye akhuliswe kakuhle, zinegalelo ngqo kwi-equation yokudlulisa ubushushu yesakhiwo.
Ngokubanzi, uyilo oluxutyiweyo lweemveliso zamatye ezikhuliswe nge-perlite luqala kwi-1:4 (binder:perlite) ukuya kwi-1:20 ngokomthamo.
Iziseko zeTanki yokugcina kunye neDama lokudada ezigqumayo
Iipropati zokukhusela ezikumgangatho ophezulu zekhonkrithi yePerlite ziyabaluleka xa zisetyenziswa ukwenza isiseko seetanki zokugcina ezingadluliseli ubushushu kunye namachibi okudada evinyl asemhlabeni. Ngokukodwa kumachibi okudada asemhlabeni, ukulahleka kobushushu emhlabeni kuncitshiswa kakhulu, ngaloo ndlela kubonelela ngobushushu obuhambelanayo phakathi kwamanzi echibini kunye nokunciphisa umthwalo kwizixhobo zokufudumeza. Ukusebenza kakuhle kwesiseko sechibi sekhonkrithi yePerlite kubonelela ngesiseko esiqinileyo nesingenamthungo see-liner zechibi zevinyl—kwaye isitshixo sobomi be-liner.
Umlinganiselo woyilo lomxube oqhelekileyo ususela kwi-1:5 (i-binder:perlite) ukuya kwi-1:8, kunye nomlinganiselo ophezulu we-perlite obonelela ngokumelana nobushushu obuphezulu. Ubuncinane ubukhulu besiseko obuziisentimitha ezimbini (5cm) buyimfuneko ukuze kufezekiswe amandla kunye neenzuzo zokukhusela.
