Perlitendi mwala wopangidwa mwachilengedwe wa siliceous womwe umagwiritsidwa ntchito popaka kutentha m'nyumba.

Kupanga
United States ndiyomwe imapanga padziko lonse lapansi komanso imagula perlite. Mayiko ena otsogola omwe amapanga perlite ndi China, Greece, Japan, Hungary, Armenia, Italy, Mexico, Philippines, ndi Turkey. Mungazindikire kuti ndi timiyala ting'onoting'ono toyera tomwe timagwiritsidwa ntchito poumba dothi kuti mpweya ukhale wabwino komanso kuti chinyezi chisamale.

Ikakumbidwa, perlite imatenthedwa mpaka pafupifupi 1,600 ° F (871 ° C), zomwe zimapangitsa kuti madzi ake asungunuke ndikupanga tinthu ting'onoting'ono tambirimbiri tomwe timapangitsa kuti mcherewo ukhale wapadera. Kutsekemera kwa perlite kumapangidwa mu mawonekedwe a granular komanso mawonekedwe a ufa, koma opanga ena amaphatikiza ndi gypsum kapena zipangizo zina kuti asandutse bolodi lotetezera. Kuphatikiza pa ntchito yake ngati insulator m'nyumba, perlite imagwiritsidwa ntchito popangira zida zotsika kutentha, monga kusungirako kuzizira kwambiri ndi akasinja a cryogenic, komanso pokonza chakudya.

Katundu Wathupi ndi Chizindikiritso

Insulation yomwe imapezeka m'nyumba imatha kupangidwa ndi perlite ngati ili ndi izi:
mtundu wake wa chipale chofewa mpaka wotuwa-woyera. Mwala wosakhwima umachokera ku imvi yowoneka bwino mpaka yakuda konyezimira, koma mawonekedwe otambasulidwa omwe amapezeka m'nyumba amadziwika mosavuta ndi mtundu wake woyera;
ndi opepuka. Perlite yowonjezera ikhoza kupangidwa kuti ikhale yolemera makilogalamu 2 pa phazi la kiyubiki; ndi/kapena
makulidwe ake ambewu amatha kusiyanasiyana, koma nthawi zambiri sakhala okulirapo kuposa ¼-inchi m'mimba mwake.

Magwiridwe a Perlite ngati Insulator

Perlite imagwiritsidwa ntchito kwambiri ngati kusungunula-kudzaza, makamaka pomanga miyala, chifukwa cha izi zomwe zimapangitsa kuti zikhale zofunika:
otsika kawopsedwe. Malinga ndi Perlite Institute, "Palibe zotsatira zoyeserera kapena chidziwitso chomwe chikuwonetsa kuti perlite imakhala pachiwopsezo cha thanzi." Ma insulators ena, monga asbestosi, vermiculite (omwe angakhale ndi asibesitosi), ndi magalasi a fiberglass ndi owopsa kwambiri;
kusowa kwa mankhwala, kutanthauza kuti sikungawononge mapaipi, magetsi kapena njira zolumikizirana. Perlite ili ndi pH yozungulira 7, yomwe ili yofanana ndi madzi abwino;
kukhazikika. Monga insulator yotayirira muzomangamanga, perlite imatha kutsanuliridwa m'mabowo a konkire komwe imadzaza ming'alu yonse, ma cores, matope ndi mabowo a makutu. Mcherewu umayenda mozungulira movutikira, kusalingana kapena kuyika kowonekera. Imathandizira kulemera kwake ndipo sichikhazikika kapena mlatho; Perlite simenti
mkulu moto mlingo. Underwriters Laboratories apeza kuti khoma la konkriti la maola awiri, la 8-inch (20.32-cm) limapangidwa bwino mpaka maola anayi pamene ma cores amadzazidwa ndi silicone-treated perlite;
zowola ndi zoletsa zowola;
kuchepetsa phokoso. Perlite loose-fill insulation imatha kudzaza ma voids onse, mizere yamatope ndi mabowo a makutu, motero imathandiza kuchepetsa kufalikira kwa mawu owuluka ndi makoma. Chopepuka, 8-inch (20-cm) chipika chodzaza ndi perlite chimakwaniritsa kalasi yotulutsa mawu ya 51, yopitilira milingo ya HUD yotumizira mawu;
zosagonjetsedwa ndi chinyezi, zomwe zimapangitsa kuti zikhale zothandiza kugwiritsidwa ntchito m'madera omwe ali ndi madzi kapena chinyontho, monga momwe zimakhalira pansi ndi zotsekera pansi; ndi
zonse zachilengedwe. Dipatimenti ya Zamagetsi ku US imalimbikitsa perlite ngati zomangira zobiriwira.
Zina zomwe zimagwiritsidwa ntchito pa perlite ngati insulator m'nyumba ndi monga:

m'miyendo ya makoma a dzenje-masonry unit;
m'mapanga apakati pa makoma omanga;
pakati pa makoma akunja amiyala ndi ubweya wamkati;
kwa kutchinjiriza pansi ndi kusanjika kwa pansi zakale. Pogwiritsa ntchito izi, kutchinjiriza kwa perlite kumatsanuliridwa pamtunda woyambira, wopindika mpaka kuya koyenera, wokutidwa ndi makatoni kapena matabwa opepuka, ndi pepala lamafuta;
mu matailosi padenga;
monga zotchingira moto kuzungulira chimney, zitseko, zipinda ndi zotetezera; ndi
za kukongoletsa denga.
Zolepheretsa

Ndi mtengo wa R wa 2.7, perlite imagwira ntchito mopanda zotetezera zina, monga fiberglass, rockwool ndi cellulose. Zimaposa ena, komabe, monga vermiculite, matabwa otayirira, ndi udzu.
Perlite ndiyosavomerezeka kuti igwiritsidwe ntchito pomwe idzawonetsedwa mwachindunji ndi kutentha kosalekeza kwa 200 ° F.
Perlite sayenera kugwiritsidwa ntchito pamalo akunja omwe nthawi zonse amakhala ndi madzi kapena chinyezi. Kumene kukhudzana ndi madzi ochulukirapo kapena chinyezi kumayembekezeredwa, pulasitala ya simenti ya Portland ikulimbikitsidwa.
Mapulasitala a Perlite savomerezedwa pamwamba pa mapanelo owala otentha chifukwa cha zomwe amateteza.
Kutentha kwakukulu komwe perlite imatha kupirira ndi 2,300º F (1,260º C).
Mwachidule, perlite ndi mchere wachilengedwe, wotetezeka womwe umagwiritsidwa ntchito ngati kutchinjiriza m'nyumba.
