Sodium metasilicate ndi mchere asidi silicic, ndi chilinganizo ake maselo akhoza kulembedwa ngati Na2SiO3 · nH2O. Sodium metasilicate ndi otsika maselo galasi anawakonzera ikukhudzana zimene wamba kuwira m'munsi ndi caustic koloko
ofanana: Sodium metasilicate pentahydrate
CAS palibe: 6834-92-0
maselo chilinganizo: Na2SiO3.5H2O
Maselo kulemera: M = 122,066
Maonekedwe: woyera galasi ufa
Sodium metasilicate pentahydrate kwambiri zamchere, ndi mphamvu amphamvu a kuyeretsa, buffering ndi olimbikitsa, zinthu zimene kuipitsidwa acidic, emulsifying mafuta ndi mafuta, deflocculating kuti zochita kupanga. Iwo akhoza m'malo STPP kuti ntchito kupanga detergents bwino ndipo dzimbiri remover chifukwa zitsulo, kuchepetsa kuwonongeka kwa malo, kuteteza dzimbiri kwa zitsulo (nthaka, zitsulo zotayidwa, etc.). Choncho, sodium metasilicate pentahydrate chimagwiritsidwa ntchito kupanga zosiyanasiyana detergents, ntchito ngati dzimbiri remover chifukwa zitsulo, akupera othandiza kwa ziwiya zadothi, deinking wothandizila mapepala, ankaudaya ndi kusindikiza wothandiza kwa kuchotsa mafuta makampani nsalu, ndipo ankagwiritsa ntchito ngati zopangira kwa flameproofing wothandizira, pulasitiki wothandizila kukonza madzi posungira wothandizira, etc. Ntchito wothandizila madzi kuchepetsa, sodium metasilicate pentahydrate amatha cigawo hydrones kwambiri kuti bwino chinyezi mayamwidwe zotsatira
