Kukhazikika kwakukulu, Gasi wambiri, Dispersibility Wabwino, Katundu wamakina abwino kwambiri

Mapulogalamu

Kutentha kwapang'onopang'ono kwamitundu yotsika kwambiri yotulutsa thovu ndipamwamba kuposa 200 ° C, ndipo kupanga mpweya kumafika 220 ml/g (kutentha kokhazikika, kuthamanga kwa mumlengalenga).Zigawo zazikulu za mpweya wopangidwa ndi kuwonongeka ndi N2, CO2, ndipo zimatsagana ndi CO ndi NH3 pang'ono.The activator (foaming accelerator) amatha kusintha kutentha kwa kutentha pakati pa 150 ndi 200 ° C. Zomwe zimagwiritsidwa ntchito ndi nthaka, cerium oxide ndi mchere wake, stearic acid ndi mchere wake.The tinthu kukula kwa thovu wothandizila ndi yunifolomu, khola thobvu ntchito, kwambiri kubalalitsidwa ntchito, makamaka oyenera kupanga mankhwala pansi pa zinthu zosiyanasiyana kupanga ndondomeko.

Kupaka ndi kusunga

Mitundu yotulutsa thovu ili ndi kukhazikika kwabwino kwa kutentha kwa chipinda ndipo iyenera kusungidwa pamalo ozizira, owuma.Khalani kutali ndi mapaipi a nthunzi yotentha ndi magwero oyatsira ndipo pewani kuwala kwa dzuwa.
Kukhudzana mwachindunji ndi zidulo ndi maziko ndikoletsedwa.Ndikoyenera kuti madera ogwirira ntchito ndi osakanikirana azikhala ndi mpweya wabwino kuti asapumedwe ndi fumbi, kukhudzana kwambiri ndi khungu ndi kuyamwa.
Chidutswa chilichonse chamagulu otulutsa thovu chimadzaza mu 25KG, ndipo chimatha kudzazidwa m'bokosi lamabokosi malinga ndi zosowa zamakasitomala.
