Perlite yokulirapo Ndiwo wopepuka kwambiri kuposa mitundu yonse ya mchere yoyenera konkire. Konkire yoteteza komanso yopepuka, ya perlite-aggregate imagwiritsidwa ntchito popanga zinthu zosiyanasiyana monga madenga, zipilala za chimney, ziboliboli, miyala yokongoletsera, matailosi, zipika za moto wa gasi, makina odzaza pansi ndi mafuta, matanki osungira mafuta, matanki oteteza kutentha ndi maziko a dziwe losambira, komanso kulimbitsa mphamvu ya mawu ndi kukana moto m'makoma, pansi ndi zitsulo zomangira.
Perlite Konkire
Ikagwiritsidwa ntchito ngati chophatikiza chachikulu mu konkriti, perlite yowonjezera imapereka maubwino angapo ofunikira pakupanga ndi kupanga zinthu zokonzedwa kale. Ngakhale konkriti yopepuka ya perlite nthawi zambiri siigwiritsidwa ntchito popanga kapena kunyamula katundu, m'magwiritsidwe ena imapereka kusintha kwa kupsinjika kwa katundu, kuchepetsa phokoso, kukana kutentha, komanso kuwunika moto.
Kawirikawiri, konkireti ya perlite ingagawidwe m'magulu awiri—yopepuka kwambiri ndi yopepuka. Konkireti ya perlite yopepuka kwambiri imakhala ndi kachulukidwe kochepera 800 kg/m3 ndipo imagwiritsidwa ntchito makamaka padenga, mabedi okwezeka, makoma a nsalu, ndi zinthu zotetezera kutentha monga matanki osungiramo gasi wachilengedwe (LNG). Konkireti ya perlite yopepuka imakhala ndi kachulukidwe kuyambira 50 mpaka 110 lb/ft3 (800 - 1800 kg/m3), imakhala ndi mchenga wa microsilica, ndipo imapereka mphamvu yolimba komanso yopindika, zomwe zimapangitsa kuti ikhale yoyenera kumaliza pansi ndi kudzaza. M'mitundu yonse iwiri, kugwiritsa ntchito chothandizira mpweya kumathandizira kugwira ntchito bwino, kumapereka malamulo okhwima, komanso kusunga kufunika kwa kutetezera kutentha.
Perlite mu Zitsime Zopangira Simenti
Kutha kwa Perlite kuthana ndi kutentha kumapereka simenti yopepuka yomwe imataya zinthu zochepa chifukwa cha kuthekera kwake kutseka malo osweka ndi kutseka ming'alu. Ubwino wina ndi monga kukolola kwakukulu pamlingo wopepuka, mphamvu zotetezera kutentha, makhalidwe abwino kwambiri otaya madzi, komanso kupsinjika kochepa kwa hydrostatic pa mapangidwe ozungulira.
Konkire Woteteza Perlite wa Ma Decks a Denga
Makina okhazikika otetezera kutentha ndi ovuta komanso ovuta kuyika ndipo amatha kutaya mpaka 30% ya mphamvu zawo zotetezera kutentha chifukwa cha kuchepa kwa zinthu, kusuntha kwa kutentha, komanso kulumikiza kutentha pamwamba pa denga lachitsulo kudzera mu zomangira zamakina. Palibe mavuto ngati amenewa ndi madenga a konkireti ya perlite. Madenga a konkireti ya perlite ndi opanda msoko, zomwe zimapangitsa kuti pakhale maziko osalala komanso ofanana a denga lolumikizidwa mwachindunji. Konkireti ya perlite ikhoza kuyikidwa pamwamba pa denga lachitsulo lopindika, konkire yokonzedwa kale kapena yothiridwa m'malo mwake, kapena ngakhale pa zipangizo zadenga zomwe zilipo kale.
Konkireti ya Perlite ndi maziko abwino kwambiri a denga lomangidwa ndi lopangidwa ndi ply imodzi. Ili ndi mphamvu yolimbana ndi mphepo ndi moto, ndipo, powonjezera polystyrene insulation yomwe ili mu konkireti ya perlite, mphamvu yolimba yolimbana ndi kutentha imatheka. Zotsatira zake: denga lolimba kwambiri lomwe lidzateteza komanso kukana moto kwa moyo wonse wa nyumbayo. Kukonzanso denga ndi nkhani yongosintha nembanemba.
Mapangidwe a konkireti ya perlite angapangidwe ndi makulidwe kuyambira 20 mpaka 50 lbs/ft3, zomwe zikutanthauza kuti dongosolo la konkireti ya perlite yokhala ndi R-30 likhoza kukhala pansi pa 8 lbs. pa sikweya mita.
Zinthu zina zofunika kuziganizira: makina osungira denga la konkireti ya perlite amatsetsereka mosavuta kuti madzi azituluka; mphamvu ya moto imatenga ola limodzi mpaka atatu; konkireti yopepuka ya perlite ikhoza kupopedwa, kutsanulidwa, kapena kupakidwa pulasitala; konkireti ya perlite yokonzedwa bwino ikhoza kukhomedwa, kudulidwa, ndikugwiritsidwa ntchito ndi zida wamba.
Kuyesa ndi Kuvomereza. Makina otetezera denga la konkriti ya Perlite ayesedwa ndikuvomerezedwa kuti agwiritsidwe ntchito pakuwunika mphepo ndi moto ndi Underwriters Laboratories, Factory Mutual, ndi mabungwe ena olamulira malamulo. Madenga a konkriti ya Perlite okhala ndi bolodi lotetezera polystyrene akukwaniritsa zofunikira za UL Class 90 ndi FM 1-90 yolimbana ndi mphepo.
Zopangidwa ndi Miyala Yokongoletsera
Ubwino waukulu wogwiritsa ntchito perlite aggregate yowonjezereka mu zinthu zopangidwa ndi miyala ndi njerwa zomwe zalimidwa (zopangidwa) ndi kusunga kulemera—kulemera kofanana ndi gawo limodzi mwa magawo atatu kuposa mapangidwe wamba osakanikirana. Kusunga kulemera kumeneko kuli ndi ubwino womveka bwino: kapangidwe kothandizira kochepa (monga makwerero ndi maziko) a veneer, komanso kusunga ndalama posamalira ndi kutumiza.
Mphamvu za konkireti ya perlite zoteteza kutentha komanso zosapsa ndi moto zimawonjezeranso phindu ku zinthu zopangidwa ndi miyala zomwe zimalimidwa, zomwe zimathandiza mwachindunji ku equation yotumiza kutentha kwa envelopu ya nyumbayo.
Kawirikawiri, mapangidwe osakaniza a zinthu zopangidwa ndi miyala zopangidwa ndi perlite aggregate amakhala kuyambira 1:4 (binder:perlite) mpaka 1:20 ndi voliyumu.
Malo Osungiramo Zinthu Zoteteza ndi Maziko a Dziwe Losambira
Mphamvu zabwino kwambiri za konkireti ya Perlite zotetezera kutentha zimagwira ntchito bwino kwambiri zikagwiritsidwa ntchito popanga maziko a matanki osungiramo zinthu osagwiritsa ntchito kutentha komanso maiwe osambira a vinyl omwe ali pansi. Makamaka maiwe osambira omwe ali pansi, kutaya kutentha m'nthaka kumachepa kwambiri, motero kumapangitsa kutentha kwa madzi a dziwe kukhala kofanana komanso kuchepetsa katundu pa zipangizo zotenthetsera. Kugwira ntchito bwino kwa maziko a dziwe la konkireti ya Perlite kumapereka maziko olimba komanso osasokonekera a ma liner a dziwe la vinyl—ndipo ndi chinsinsi cha moyo wautali wa ma liner.
Ma ratio a kapangidwe ka kusakaniza nthawi zambiri amakhala kuyambira 1:5 (binder:perlite) mpaka 1:8, ndipo ma ratio apamwamba a perlite amapereka kukana kutentha kwambiri. Kufunika kokhala ndi makulidwe osachepera a maziko a mainchesi awiri (5cm) kuti mupeze mphamvu ndi ubwino woteteza kutentha.
