Gulu losinthidwa la phenolic insulation limapangidwa ndi thovu la phenolic.Zigawo zake zazikulu ndi phenol ndi formaldehyde.Phenolic thovu ndi mtundu watsopano wa zinthu zoletsa moto, zosagwira moto komanso zotsika utsi (pansi pamikhalidwe yochepa).Amapangidwa ndi utomoni wa phenolic wokhala ndi thovu, thovu lotsekeka la cell lopangidwa ndi machiritso ndi zina zowonjezera.Phenolic thovu ndi utomoni wa phenolic monga chopangira chachikulu, chowonjezera chochiritsa, chotulutsa thovu ndi zinthu zina zothandizira, pomwe utomoniwo umalumikizidwa ndi kulimba, wotulutsa thovu umatulutsa mpweya womwazika mmenemo ndikuchita thovu kupanga thovu.Zosinthidwa phenolic fireproof insulation board ili ndi zabwino zambiri:
(1) Ili ndi mawonekedwe otsekeka a cell, kutsika kwamafuta otsika, komanso magwiridwe antchito amatenthedwe ofanana ndi polyurethane, kuposa thovu la polystyrene;
(2) Pansi pa moto wachindunji, pamakhala mapangidwe a kaboni, osadontha, osapiringizika, komanso osasungunuka.Lawi lamoto likayaka, "chithovu cha graphite" chimapangidwa pamwamba, chomwe chimateteza bwino mawonekedwe a thovu mu wosanjikiza ndikukana kulowa kwa lawi.Nthawi imatha kufika 1 h;
(3) Kuchuluka kwa ntchito ndi kwakukulu, mpaka -200～200 ℃, ndipo angagwiritsidwe ntchito kwa nthawi yaitali pa 140～160 ℃;
(4) Mamolekyu a phenolic amangokhala ndi maatomu a carbon, haidrojeni, ndi mpweya.Zikawonongeka pa kutentha kwakukulu, palibe mpweya wina wapoizoni kupatulapo pang'ono CO. Kuchuluka kwa utsi ndi 5.0%;
(5) Kuphatikiza pa kukhala ndi dzimbiri ndi alkalis amphamvu, thovu la phenolic limatha kupirira pafupifupi ma asidi onse, ma organic acid, ndi zosungunulira.Yaitali kukhudzana ndi dzuwa, palibe zoonekeratu kukalamba chodabwitsa, poyerekeza ndi organic matenthedwe kutchinjiriza zipangizo, moyo wake utumiki ndi wautali;
(6) Lili ndi dongosolo labwino lotsekedwa, kutsekemera kwa madzi otsika, kulowerera kwamphamvu kwa nthunzi, ndipo palibe condensation panthawi yozizira;
(7) Kukula kwake kumakhala kokhazikika, kusintha kwa kusintha kumakhala kochepa, ndipo kusintha kwa kukula kumakhala kochepa kuposa 4% mkati mwa kutentha kwa ntchito.
Bolodi yotchinjirizidwa ya phenolic yotchinga moto yakhala njira yayikulu yogwiritsira ntchito ngati zotchingira kutentha komanso zomangira zotchingira moto.Amagwiritsidwa ntchito kwambiri pamakina akunja otchingira khoma: makina opaka pulasitala akunja kwa makoma akunja, kutsekereza khoma lagalasi, kutsekereza zokongoletsera, kutsekereza khoma lakunja ndi malamba otsekereza moto, ndi zina zambiri.
