Perlite ndi mwala wachilengedwe wa siliceous womwe umagwiritsidwa ntchito poteteza kutentha m'nyumba.

Kupanga
Dziko la United States ndi lomwe limapanga komanso kugwiritsa ntchito perlite kwambiri padziko lonse lapansi. Mayiko ena otsogola omwe amapanga perlite ndi China, Greece, Japan, Hungary, Armenia, Italy, Mexico, Philippines, ndi Turkey. Mutha kuzindikira kuti ndi miyala yaying'ono yoyera yomwe imagwiritsidwa ntchito popangira nthaka kuti iwonjezere mpweya komanso kusunga chinyezi.

Pambuyo poikumba, perlite imatenthedwa kufika pa 871°C (1,600°F), zomwe zimapangitsa kuti madzi ake asungunuke ndikupanga thovu laling'ono kwambiri lomwe limayimira mawonekedwe apadera a mcherewu. Kuteteza kwa perlite kumapangidwa mu mawonekedwe a granular komanso ngati ufa, koma opanga ena amaphatikiza ndi gypsum kapena zinthu zina kuti asinthe kukhala bolodi loteteza. Kuwonjezera pa kugwiritsidwa ntchito ngati chotetezera m'nyumba, perlite imagwiritsidwa ntchito poteteza zida zotentha kwambiri, monga malo osungiramo zinthu ozizira kwambiri ndi matanki a cryogenic, komanso pokonza chakudya.

Katundu ndi Kuzindikiritsa

Chotetezera kutentha chomwe chimapezeka m'nyumba chingapangidwe ndi perlite ngati chili ndi makhalidwe awa:
Mtundu wake ndi woyera ngati chipale chofewa mpaka woyera ngati imvi. Mwala wosaphika umayambira pa imvi yowala mpaka wakuda wonyezimira, koma mawonekedwe ofutukuka omwe amapezeka m'nyumba amadziwika mosavuta ndi mtundu wake woyera;
Ndi yopepuka. Perlite yokulirapo imatha kupangidwa kuti ikule mapaundi awiri pa kiyubiki futi; ndi/kapena
Kukula kwake kwa tinthu tating'onoting'ono tingasiyane, koma nthawi zambiri sikokulirapo kuposa ¼-inch m'mimba mwake.

Magwiridwe antchito a Perlite ngati chotetezera kutentha

Perlite imagwiritsidwa ntchito kwambiri ngati chotetezera kutentha, makamaka pomanga nyumba zamatabwa, chifukwa cha makhalidwe awa omwe amawapangitsa kukhala ofunikira:
poizoni wochepa. Malinga ndi Perlite Institute, “Palibe zotsatira za mayeso kapena chidziwitso chomwe chikusonyeza kuti perlite imayambitsa chiopsezo chilichonse pa thanzi.” Zotetezera zina, monga asbestos, vermiculite (yomwe ingakhale ndi asbestos), ndi fiberglass ndi zoopsa kwambiri;
Kusagwira ntchito kwa mankhwala, kutanthauza kuti sikuwononga mapaipi, njira zamagetsi kapena zolumikizirana. Perlite ili ndi pH ya pafupifupi 7, yomwe ndi yofanana ndi madzi abwino;
kusinthasintha. Monga chotetezera kutentha chomwe chimayikidwa mu zomangamanga za miyala, perlite imatha kutsanuliridwa m'mabowo a konkriti komwe imadzaza ming'alu yonse, madera a matope, ndi mabowo a makutu. Mcherewo umayendayenda mozungulira malo aliwonse ovuta, osafanana kapena malo owonekera. Umathandizira kulemera kwake ndipo sudzakhazikika kapena kutsekeka; simenti ya perlite
Kuchuluka kwa moto. Underwriters Laboratories yapeza kuti khoma la konkire lokhala ndi mainchesi 8 (20.32-cm) lomwe lili ndi mainchesi 20.32 limasinthidwa kukhala maola anayi pamene ma cores amadzazidwa ndi perlite yokonzedwa ndi silicone;
yolimba kuola ndi kupirira tizilombo toyambitsa matenda;
Kuchepetsa phokoso. Chotetezera kutentha cha perlite chimatha kudzaza malo onse opanda kanthu, mizere ya matope ndi mabowo a makutu, motero chimathandiza kuchepetsa kutumiza mawu kudzera m'mlengalenga kudzera m'makoma. Chipika chopepuka, cha mainchesi 8 (20-cm) chodzazidwa ndi perlite chimakwaniritsa kalasi yotumizira mawu ya 51, kupitirira miyezo yotumizira mawu ya HUD;
kupirira chinyezi, zomwe zimapangitsa kuti ikhale yothandiza kugwiritsidwa ntchito m'malo omwe madzi kapena chinyezi chilipo, monga m'malo osungira pansi ndi pansi; ndi
Zonse ndi zachilengedwe. Dipatimenti ya Zamagetsi ku US imalimbikitsa perlite ngati zinthu zomangira zobiriwira.
Ntchito zina zodziwika bwino za perlite ngati chotetezera kutentha m'nyumba ndi izi:

m'mizere ya makoma a unit oboola pakati;
m'mabowo pakati pa makoma a miyala;
pakati pa makoma akunja a miyala ndi ubweya wamkati;
poteteza pansi pa nthaka ndi kulinganiza pansi zakale. Pogwiritsira ntchito izi, kutetezera kwa perlite kumathiridwa pamwamba pa pansi poyambirira, kumakulungidwa bwino, kuphimbidwa ndi makatoni kapena matabwa opepuka, ndi pepala lamafuta;
mu matailosi a padenga;
monga zotetezera moto kuzungulira ma chimney, zitseko, zipinda ndi ma safes; ndi
zomangira denga.
Zoletsa

Ndi mtengo wa R wa 2.7, perlite imagwira ntchito mochepa kuposa ma insulators ena, monga fiberglass, rockwool ndi cellulose. Komabe, imaposa ena monga vermiculite, zinthu zamatabwa zotayirira, ndi udzu.
Perlite sivomerezeka kugwiritsidwa ntchito pamene idzawonekera mwachindunji kutentha kosalekeza kwa 200°F.
Perlite sayenera kugwiritsidwa ntchito pamalo akunja omwe nthawi zambiri amakhala ndi madzi kapena chinyezi. Ngati pakufunika kukhudzana ndi madzi kapena chinyezi chochuluka, pulasitala wa simenti wa Portland amalimbikitsidwa.
Ma plaster a perlite sakuvomerezeka kuposa ma radiant heating panels chifukwa cha mphamvu zawo zotetezera kutentha.
Kutentha kwakukulu komwe perlite ingapirire ndi 2,300º F (1,260º C).
Mwachidule, perlite ndi mchere wachilengedwe komanso wotetezeka womwe umagwiritsidwa ntchito ngati chotetezera kutentha m'nyumba.
