I-perlite eyandisiweyo yeyona ikhaphukhaphu kuzo zonke iiaggregates zeeminerali ezifanelekileyo kwikhonkrithi. I-concrete ye-insulative kunye ne-lightweight, i-perlite-aggregate concrete isetyenziselwa iinkqubo ezahlukeneyo zokwakha kunye neemveliso zoshishino-kubandakanywa iidekhi zephahla, i-chimney linings, i-stuary, ilitye lokuhombisa, i-tile mortars, i-gas fireplace logs, iinkqubo zomgangatho kunye nokuzaliswa, iitanki zokugcina i-fuel, itanki ye-insulating. kunye neziseko zamadama, kunye nokukhuthaza isandi kunye neepropati zokumelana nomlilo kwiindonga, imigangatho kunye nentsimbi yesakhiwo.
PerliteEkhonkrithi
Xa isetyenziswa njengeyona ndawo iphambili kwikhonkrithi, i-perlite eyandisiweyo ibonelela ngeenzuzo ezininzi eziphambili kulwakhiwo kunye nezicelo zokwenziwa kwangaphambili. Nangona ikhonkrithi ekhaphukhaphu yeperlite iqhele ukungalungeli ukusetyenziswa kolwakhiwo okanye ukuthwala umthwalo, kwezinye izicelo ibonelela ngophuculo kuxinzelelo lomthwalo, ukucutha ingxolo, ukuxhathisa kokufuduswa kobushushu, kunye nomgangatho womlilo.
Ngokuqhelekileyo, ikhonkrithi ye-perlite inokwahlulwa ibe ngamacandelo amabini-Ultralight kunye ne-Lightweight. Iconcrete yeUltralight perlite inoxinano olungaphantsi kwe50 lbs/ft3 (800 kg/m3) kwaye isetyenziswa ikakhulu kuphahla lwemigangatho, iibhedi zokutyala eziphakanyisiweyo, iindonga zamakhethini, kunye nezicelo zokugquma okusisigxina ezifana neitanki zokugcina igesi enyibilikisiweyo (LNG). Ikhonkrithi ekhanyayo yeperlite inoxinano ukusuka kwi-50 ukuya kwi-110 lb / ft3 (800 - 1800 kg / m3), ibandakanya isanti ye-microsilica, kwaye inika amandla aphezulu oxinzelelo kunye nokuguquguquka, okwenza umgangatho ofanelekileyo ugqibe kwaye uzalise. Kuzo zombini iintlobo, ukusetyenziswa kwe-agent-entraining agent iphucula ukusebenza, inikezela ukulawulwa koxinano, kwaye igcina ixabiso le-insulation.
Perlite kwi Well Cements
Isakhono sePerlite sokuphatha ubushushu sibonelela ngesiseko sesamente esikhaphukhaphu esisebenzayo esibonisa ilahleko encinci yemathiriyeli ngenxa yobuchule bayo bokuvala i-voids kunye nokutywinwa koqhekeko. Olunye uncedo lubandakanya isivuno esikhulu kuxinaniso olukhaphukhaphu, iimpawu zokugquma, iimpawu ezibalaseleyo zokuphulukana nolwelo, kunye noxinzelelo oluphantsi lwe-hydrostatic kulwakhiwo olujikelezileyo.
I-Perlite Insulating Concrete kwiDesika yophahla
Iinkqubo zokugquma eziqinileyo eziqhelekileyo zintsonkothile kwaye kunzima ukuzifakela kwaye zinokuphulukana nokuya kutsho kuma-30% exabiso lazo lokugquma elipapashiweyo ngenxa yokuncipha kwemveliso, ukukhukuliseka kwe-thermal, kunye nebhulorho eshushu phezu kwedesika yentsimbi ngokusebenzisa iziqhoboshi zoomatshini. Akukho miba enjalo kunye nophahla lwekhonkrithi ye-perlite. Iidekhi zophahla lwekhonkrithi yeperlite azinamthungo, zibonelela ngesiseko esigudileyo, esine-monolithic sokubambelela ngokuthe ngqo kophahla. Iconcrete yeperlite inokubekwa phezu kwentsimbi ehonjisiweyo efakwe igalvanized, iprecast okanye ikhonkrithi egalelwe endaweni, okanye nangaphezulu kwezixhobo zophahla ezivakalayo.
Ikhonkrithi yePerlite sisiseko esifanelekileyo sokwakhiwa kunye neenkqubo zophahla olulodwa. Inomoya ophezulu kunye nokumelana nomlilo, kwaye, kunye nokongezwa kwe-polystyrene insulation sandwiched kwi-concrete ye-perlite, amaxabiso aphezulu okumelana ne-thermal afezekiswa ngokwezoqoqosho. Isiphumo: idesika yophahla eyomelele ngokumangalisayo eya kuthi igqume kwaye imelane nomlilo ubomi besakhiwo bonke. Uphahla ngokutsha ngumcimbi kuphela wokutshintsha inwebu.
Ukuxutywa kwe-concrete ye-Perlite kungenziwa ngoxinaniso ukusuka kwi-20 ukuya kwi-50 lbs / ft3, oku kuthetha ukuba inkqubo yophahla lwekhonkrithi ye-perlite enomlinganiselo we-R-30 inokungena ngaphantsi kwe-8 lbs. ngonyawo ngalunye lwesikwere.
Ezinye izinto eziqwalaselwayo ekudlaleni: Iisistim zedekhi yophahla lwekhonkrithi eneperlite zithambeka lula ukuze zikhuphe amanzi; ukulinganiswa komlilo ukusuka kwi-1 ukuya kwiiyure ze-3 kunokwenzeka; Iconcrete yeperlite ekhaphukhaphu inokumpontshwa, igalelwe, okanye ityatyekwe endaweni; ikhonkrithi enyangisiweyo yeperlite inokubethelelwa, isarha, kwaye isetyenzwe ngezixhobo eziqhelekileyo.
Uvavanyo kunye nokuVunywa. Iinkqubo zokugquma uphahla lwekhonkrithi yeperlite ziye zavavanywa kwaye zamkelwa ukulinganisa umoya kunye nomlilo yi-Underwriters Laboratories, iFactory Mutual, kunye namanye amagunya ekhowudi. Iidekhi zophahla lwekhonkrithi yePerlite ezinebhodi yokugquma i-polystyrene ziyahlangabezana nemilinganiselo ye-UL Class 90 kunye ne-FM 1-90 yokumelana nomoya.
IiMveliso zamatye eziHonjisiweyo ezenziweyo
Inzuzo enkulu yokusebenzisa i-perlite aggregate eyandisiweyo kwimveliso yamatye kunye nezitena ezikhuliswe (ezenziwe) kunye nemveliso ye-veneer yezitena kukugcinwa kobunzima-ubuninzi besithathu kubunzima bokuyila komxube oqhelekileyo. Oko kugcinwa kobunzima kuneengenelo ezicacileyo: ulwakhiwo lwenkxaso olungaphantsi olungqongqo (njengamaleji kunye neenyawo) kwi-veneer, kunye nokugcinwa kweendleko ekuphatheni nasekuthumeleni.
Iipropati ze-Perlite zekhonkrithi ezikhuselayo kunye nokumelana nomlilo nazo zongeza ixabiso kwiimveliso zamatye ezikhulisiweyo, ezincedisa ngokuthe ngqo kwi-equation yokudlulisa ubushushu kwimvulophu yokwakha.
Ngokuqhelekileyo, idizayini yokuxuba yeemveliso zamatye ezisekelwe kwi-perlite zivela kwi-1: 4 (i-binder: perlite) ukuya kwi-1:20 ngevolumu.
I-Insulating Storage Tank kunye neziseko zePool
Iipropathi ezigqwesileyo zekonkrithi yeperlite ziyangena ngokwenene xa zisetyenziswa ukwenza isiseko samatanki okugcina axhathisa ubushushu kunye namachibi okuqubha e-vinyl angaphakathi. Ngokukodwa kumadama okuqubha asemhlabeni, ilahleko yobushushu emhlabeni iyancipha kakhulu, ngaloo ndlela ibonelela ngobushushu obungaguqukiyo bamanzi echibini kunye nokunciphisa umthwalo kwizixhobo zokufudumeza. Ukusebenza okugudileyo kwesiseko sepool yekhonkrithi ye-perlite kunika isiseko esiqinileyo, esingenamthungo se-vinyl pool liners-kunye nesitshixo sobomi obude beentambo.
Imilinganiselo yoyilo lomxube oqhelekileyo ukusuka kwi-1: 5 (i-binder: i-perlite) ukuya kwi-1: 8, kunye nemilinganiselo ephezulu ye-perlite enika ukuchasana kwe-thermal conductivity. Ubuncinci besiseko sobunzima bee-intshi ezimbini (5cm) buyimfuneko ukufezekisa amandla kunye neenzuzo ezikhuselayo.
