Kuwonjezera perlite ndiye wopepuka kwambiri pamagulu onse amchere oyenera konkriti. Konkire ya perlite-aggregate imagwiritsidwa ntchito pomanga ndi mafakitale osiyanasiyana - kuphatikizapo denga, zitsulo zotchinga, miyala yokongoletsera, miyala ya matailosi, zipika zamoto wa gasi, pansi ndi zodzaza, matanki osungira mafuta, thanki yotetezera. ndi zoyambira zamadziwe, komanso kukulitsa mphamvu zomveka komanso zosagwira moto m'makoma, pansi ndi zitsulo zamapangidwe.
PerliteKonkire
Mukagwiritsidwa ntchito ngati gawo loyamba mu konkriti, perlite yokulitsidwa imapereka maubwino angapo pakumanga ndi kupanga precast. Ngakhale konkriti yopepuka ya perlite nthawi zambiri siyenera kugwiritsidwa ntchito pamapangidwe kapena kunyamula katundu, muzinthu zina imapereka kusintha kwa kupsinjika kwa katundu, kuchepetsa phokoso, kukana kusuntha kwamafuta, komanso kuvotera moto.
Nthawi zambiri, konkire ya perlite imatha kugawidwa m'magulu awiri - Ultralight ndi Lightweight. Ultralight perlite konkire imakhala ndi kachulukidwe kochepera 50 lbs/ft3 (800 kg/m3) ndipo imagwiritsidwa ntchito makamaka pamadenga apadenga, mabedi odzala okwera, makoma otchinga, ndi zida zotsekera kosatha monga matanki osungiramo gasi wachilengedwe (LNG). Konkire yopepuka ya perlite imakhala ndi kachulukidwe kuchokera ku 50 mpaka 110 lb/ft3 (800 - 1800 kg/m3), imaphatikizapo mchenga wa microsilica, ndipo imapereka mphamvu yopondereza komanso yopindika, kupangitsa kuti ikhale yoyenera kumaliza ndikudzaza. M'mitundu yonse iwiri, kugwiritsa ntchito chopangira mpweya kumapangitsa kuti ntchito ziziyenda bwino, imathandizira kachulukidwe, ndikusunga mtengo wotsekereza.
Perlite mu Well Cement
Kutha kwa Perlite kunyamula kutentha kumapereka simenti yopepuka yopepuka yomwe imawonetsa kutayika pang'ono kwazinthu chifukwa chakutha kwake kutsekereza voids ndikumata zothyoka. Ubwino wina ndi monga zokolola zazikulu pa kachulukidwe kopepuka, mikhalidwe yotsekereza, mawonekedwe abwino kwambiri otaya madzimadzi, komanso kutsika kwamphamvu kwa hydrostatic pamapangidwe ozungulira.
Perlite Insulating Concrete kwa Decks Padenga
Makina otchinjiriza okhazikika ndi ovuta komanso ovuta kuyika ndipo amatha kutaya mpaka 30% yamitengo yawo yotchinjiriza yomwe yasindikizidwa chifukwa cha kuchepa kwazinthu, kutsika kwamafuta, komanso kumangirira mlatho pamwamba pazitsulo zachitsulo kudzera pazitsulo zamakina. Palibe zovuta zotere ndi denga la konkriti la perlite. Denga la konkriti la perlite ndi lopanda msoko, lomwe limapereka maziko osalala, ngakhale a monolithic azitsulo zomata molunjika. Konkire ya perlite imatha kuyikidwa pamwamba pazitsulo zotsekera, zoyikapo kapena zothiramo konkire, kapenanso pazida zofolera zomwe zilipo.
Perlite konkire ndi maziko abwino opangira makina omangira komanso opangira denga limodzi. Ili ndi mphepo yapamwamba komanso kukana moto, ndipo, ndi kuwonjezera kwa polystyrene insulation sandwiched mu perlite konkire, mkulu matenthedwe kukana makhalidwe chuma apindula. Zotsatira zake: denga lolimba modabwitsa lomwe lingatseke ndi kukana moto kwa moyo wonse wanyumbayo. Kumanganso denga ndi nkhani yongosintha nembanembayo.
Zosakaniza za konkriti za perlite zitha kupangidwa ndi kachulukidwe kuchokera pa 20 mpaka 50 lbs/ft3, kutanthauza kuti denga la konkire la perlite lomwe lili ndi R-30 lingalowe pansi pa 8 lbs. pa phazi lalikulu.
Mfundo zina zomwe zikuseweredwa: denga la konkire la perlite limatsetsereka mosavuta kuti lichotse madzi; mavoti amoto kuyambira maola 1 mpaka 3 ndizotheka; konkire yopepuka ya perlite imatha kuponyedwa, kutsanuliridwa, kapena kupakidwa m'malo mwake; konkire wochiritsidwa perlite akhoza kukhomeredwa, kuchekedwa, ndi ntchito ndi zipangizo wamba.
Kuyesedwa ndi Kuvomereza. Makina otchinjiriza padenga la konkire ya Perlite adayesedwa ndikuvomerezedwa kuti azitha kuwongolera mphepo ndi moto ndi Underwriters Laboratories, Factory Mutual, ndi maulamuliro ena. Denga la konkriti la perlite lokhala ndi bolodi lotsekera la polystyrene limakwaniritsa zofunikira za UL Class 90 ndi FM 1-90 kukana mphepo.
Zopangidwa Zokongoletsera Mwala
Ubwino waukulu wogwiritsa ntchito miyala ya perlite yowonjezera (yopangidwa) ndi miyala yamatabwa ndi njerwa ndikuchepetsa kulemera kwake - molingana ndi gawo limodzi mwa magawo atatu a kulemera kwake kuposa momwe amasakaniza. Kuchepetsa kulemera kumeneko kuli ndi ubwino woonekeratu: dongosolo lothandizira losakhazikika (monga ma ledge ndi zopondapo) za veneer, ndi kupulumutsa ndalama poyendetsa ndi kutumiza.
Perlite konkriti zoteteza komanso zosagwira moto zimawonjezeranso phindu pazamwala wotukuka, zomwe zimathandizira mwachindunji kutengera kutentha kwa envelopu yomanga.
Nthawi zambiri, sakanizani mapangidwe a miyala ya perlite yokhazikika kuyambira 1:4 (binder: perlite) mpaka 1:20 ndi voliyumu.
Tanki Yosungirako Insulating ndi Maziko Oyimbira
Perlite konkriti yapamwamba kwambiri imayamba kugwira ntchito ikagwiritsidwa ntchito popanga maziko a matanki osungira osagwira kutentha komanso maiwe osambira a vinyl. Kwa maiwe osambira apansi, kutentha kwa pansi kumachepa kwambiri, motero kumapangitsa kuti madzi azitentha kwambiri komanso kuchepetsa katundu pazida zotenthetsera. Kuthekera kosalala kwa dziwe la konkriti la perlite kumapereka maziko olimba, opanda msoko a vinyl pool liners - komanso chinsinsi cha moyo wautali wa zomangira.
Kuphatikizika kosakanikirana kofananira kumayambira 1: 5 (binder: perlite) mpaka 1: 8, ndi kuchuluka kwa perlite komwe kumapereka kukana kwamafuta ambiri. Kukula kocheperako kwa mainchesi awiri (5cm) ndikofunikira kuti mukwaniritse mphamvu ndi zopindulitsa.
