Zida zina zozungulira m'makampani zakhala zikugwira ntchito kutentha kwa 900 ° C kwa nthawi yayitali. Zomwe zimagonjetsedwa zimakhala zovuta kufika pamtunda wa ceramic sintering pa kutentha uku, zomwe zimakhudza kwambiri ntchito ya zipangizo zokana; Ubwino wasodium hexametaphosphate mu refractory castable and spray filling ndikuti ili ndi mphamvu yokhazikika komanso yabwino yopondereza komanso kukana kuvala komanso kukana kugwedezeka kwamafuta. Zimathandizira kulimbitsa zomangira zomangira zazinthu zokanira, ndipo zimatha kupanga zinthu zaufa kapena granular refractory kugwirizana kuti ziwonetse mphamvu zokwanira.

Pakukula kwanthawi yayitali kwa zida zozungulira, mwachitsanzo, chotenthetsera mwachitsanzo, chifukwa cha kuthamanga kwa tinthu toyaka, kutentha kwambiri kumakhala ndi kukokoloka kwamphamvu komanso kukhudzidwa pazida zokanira, makamaka chipinda choyatsira moto ndi cholekanitsa chimphepo. ndi mbali zina pansi pa kuvala ndi kutenthedwa kwa kutentha kwa tinthu tating'onoting'ono, kutuluka kwa mpweya ndi fumbi, zomwe zimapangitsa kukokoloka, kuvala, kupukuta ndi kugwa kwa akalowa a zipangizo zokana. Zimakhudza kwambiri ntchito yabwino komanso kupanga kwa boiler.

Chifukwa chake, ndikofunikira kupanga zomangira zatsopano zokhala ndi kutentha kwambiri, kukana kwa dzimbiri, kukana kuvala komanso kukana kugwedezeka kwamafuta kuti zithandizire kukonza magwiridwe antchito azinthu zotsutsa.

Sodium hexametaphosphate ali ndi ubwino mu refractory castable ndi kupopera kudzazidwa. Kupyolera mu kusankha zikuchokera chiŵerengero ndi kukonzekera ndondomeko magawo, ndi binder ndi ndale kuyimitsidwa kubalalitsidwa dongosolo, amene osati ali amphamvu adhesion ndipo palibe dzimbiri kwa masanjidwewo zitsulo, komanso ali osiyanasiyana kutentha ntchito kutentha kugonjetsedwa ndi zomanga binder.

Sodium hexametaphosphateimapangidwa ndi hydrolyzed kukhala sodium dihydrogen phosphate (NaH2PO4) ikagwiritsidwa ntchito ngati chomangira muzitsulo zopopera komanso zopopera. NaH2PO4 ndi zitsulo zamchere zamchere zamchere monga magnesia zimakonzedwa kuti zisakanizike, zimatha kuchitapo kanthu kutentha kwa chipinda kupanga Mg(H2PO4)2. Mg(H2PO4)2 posakhalitsa imauma kuti ipangike [Mg(PO3)2]n ndi [Mg2(P2O7)]n, zomwe zimawonjezera mphamvu ya zovutazo ndikupereka mphamvu zochulukirapo pakutentha kosiyanasiyana (mpaka 800°). C) pamaso pa kukhalapo kwa madzi gawo.

Zipangizo zotsutsa ndizofunikira kwambiri zachitsulo ndi chitsulo, zomangira, zitsulo zopanda chitsulo, petrochemical, makina, mphamvu yamagetsi, kuteteza chilengedwe ndi mafakitale ena otentha kwambiri. Sodium hempetaphosphate chomangira ndichinthu chofunikira kwambiri pamitundu yonse yamafuta otentha a mafakitale ndi zida.
