JM30 kutchinjiriza firebrick amapangidwa kuchokera mkulu chiyero refractory dongo ndi pang'onopang'ono kuwonjezeka zotayidwa aluminium okusayidi ndipo mosamala amakhuta ndi organic kudzazidwa, amene amayaka pa ntchito kupanga, kuchititsa homogeneous, ankalamulira porous dongosolo. Kuti tikwaniritse kulekerera kofunikira, makoma onse asanu ndi limodzi a njerwa iliyonse amakonzedwa mwamakina.

Njerwa yamoto ya JM30 imagwiritsidwa ntchito kwambiri ngati gawo loyamba lazitsulo zokanira kapena ngati zotchingira kumbuyo kwa zigawo zina zonse zokanira mu ng'anjo, zowotcha, ngalande zamoto, zipinda zoyenga ndi ng'anjo zotenthetsera, zowonjezera, zopangira gasi ndi ma conduits, ng'anjo zomwe zimapangidwira, ng'anjo zochepetsera nkhawa, zipinda zochitira riyakitala ndi zida zofananira zomwe zimatentha kwambiri m'mafakitale.
Fakitale ya RS refractory ndi katswiri wogulitsa njerwa za JM30 zomwe zidakhazikitsidwa koyambirira kwa zaka za m'ma 90s zaka makumi awiri. Fakitale ya RS refractory yakhazikika mu njerwa yamoto ya JM30 kwa zaka zopitilira 20. ngati mukufuna zina za JM30 insulation firebricks, kapena muli ndi mafunso pa JM30 insulation refractory block zokhudzana ndi zizindikiro zakuthupi ndi mankhwala, chonde titumizireni kwaulere.
