PIR vs Rock Weal: Chitsogozo cha Sandwich Panel

Gulu la masangwejiMayankho amagwira ntchito yofunika kwambiri m'malo osungira zinthu zozizira, mafakitale opangira zitsulo, ndi malo osungiramo zinthu, komwe magwiridwe antchito a insulation ndi chitetezo cha moto zimakhudza mwachindunji ndalama zamagetsi ndi ntchito yanthawi yayitali. Kusankha zinthu zoyenera sikophweka. Makontrakitala ndi opanga mapulogalamu a EPC ayenera kulinganiza kutsatira malamulo a moto, kugwiritsa ntchito bwino kutentha, komanso bajeti ya polojekiti. Pakati pa zosankha zambiri, PIR ndi ubweya wa miyala zimakhalabe zipangizo zotetezera kutentha zomwe zimagwiritsidwa ntchito kwambiri pakupanga zamakono.

Chilichonse chili ndi mphamvu ndi zofooka zomveka bwino. Kusankha koyenera kumadalira mtundu wa polojekiti, zofunikira pakuwunika moto, komanso momwe zinthu zilili. M'malo mofunsa kuti ndi iti yabwino, opanga zisankho ayenera kuyang'ana kwambiri pa yankho lomwe likugwirizana ndi polojekitiyo.

Njira Yogwirira Ntchito ndi Kutsatira Malamulo a Chitetezo cha Moto

Chitetezo cha moto nthawi zambiri chimakhala chinthu choyamba pa ntchito zazikulu. Ubweya wa miyala umapereka ntchito yabwino kwambiri m'derali. Monga chinthu chosapangidwa ndi zinthu zachilengedwe, umapeza gulu la A1 losayaka pansi pa miyezo monga EN 13501. Siwotentha kapena kutulutsa utsi woopsa pakakhala moto. Izi zimapangitsa kuti ukhale woyenera malo owopsa monga malo osungiramo zinthu zozizira, nyumba zopangira mankhwala, ndi mafakitale akuluakulu. M'madera monga Russia ndi Northern Europe, makina otsekera m'nyumba zosungiramo zinthu kapena mafakitale nthawi zambiri amagwiritsa ntchito mapanelo a sandwich a ubweya wa miyala chifukwa amatha kupereka chitetezo komanso kuteteza moto.

PIR, monga chinthu choteteza kutentha kwachilengedwe, imapereka kukana moto pang'ono poyerekeza ndi ubweya wa miyala. Nthawi zambiri imakwaniritsa magulu a B-s1, d0 kapena ofanana, kutengera kapangidwe kake ndi kapangidwe ka makina. Pakakhala moto, imatha kuwola ndikutulutsa utsi. Pachifukwa ichi, mapanelo oteteza kutentha kwa PIR nthawi zambiri amafunikira njira zina zotetezera moto. Izi zimaphatikizapo zotchingira moto, zokutira zoteteza, kapena makina opopera kuti akwaniritse zomwe polojekiti ikutsatira.

Mu ntchito yeniyeni ya uinjiniya, njira zosakanikirana zimakhala zofala. Omanga nthawi zambiri amaphatikiza mapanelo a PIR ndi zotchingira moto za ubweya wa miyala kuti agwirizane ndi kuteteza kutentha ndi chitetezo cha moto. Njira imeneyi imapangitsa kuti kutsata malamulo kutsatidwe komanso kuti mphamvu zizigwira ntchito bwino. Njira zomveka bwino zopangira moto ndi kuphatikiza bwino makina ndizofunikira kuti zivomerezedwe komanso kuti inshuwalansi ikwaniritse zofunikira.

Kugwira Ntchito Mwachangu ndi Zochitika Zogwiritsira Ntchito

Kugwira ntchito kwa kutentha ndi chinthu china chofunikira kwambiri pakusankha ma panel a masangweji. PIR imapereka mphamvu yotsika ya kutentha, nthawi zambiri pafupifupi 0.022–0.024 W/(m·K). Izi zimathandiza kuti makulidwe a panel akhale ochepa kwambiri pa cholinga chomwecho chotetezera kutentha. Zimathandiza kuchepetsa kugwiritsa ntchito zinthu ndikuwonjezera malo amkati, zomwe ndizofunikira m'malo ozizira komanso m'nyumba zosungiramo zinthu zotentha.

Mapanelo a ubweya wa miyala amasonyeza kutentha kwakukulu, nthawi zambiri pakati pa 0.036–0.040 W/(m·K). Izi zikutanthauza kuti makoma okhuthala amafunika kuti afike pamlingo womwewo wa kutchinjiriza. Komabe, ubweya wa miyala umagwira ntchito bwino kutentha kwambiri ndipo umasunga miyeso yokhazikika pakapita nthawi. Umaperekanso kutchinjiriza kwabwino kwa mawu komanso kukana madera ovuta a mafakitale.

Kugwira ntchito kwa chinyezi kuyeneranso kuganiziridwa. PIR ili ndi kapangidwe ka maselo otsekedwa komwe kamalimbana ndi kulowa kwa chinyezi. Ubweya wa miyala umafuna kutseka koyenera ndi zotchinga za nthunzi kuti upitirize kugwira ntchito bwino m'malo onyowa. Chifukwa chake, kapangidwe ka polojekiti kayenera kukhala ndi dongosolo lonse la zomangamanga m'malo mongoyang'ana pa zipangizo zokha.

Ndondomeko ya akatswiri yogwiritsira ntchito sandwich panel siidalira chinthu chimodzi. Imaphatikiza chitetezo cha moto, zolinga za kutentha, ndi zoletsa za polojekiti kukhala yankho limodzi. Pogwiritsa ntchito ma panel otetezedwa kapena makina ophatikizika a ma panel m'njira yokonzedwa bwino, makontrakitala amatha kukwaniritsa zonse ziwiri kutsatira malamulo ndi kuchita bwino. Njira imeneyi imachepetsa chiopsezo, imawongolera mtengo, komanso imathandizira kupambana kwa polojekiti kwa nthawi yayitali.
