Sodium pentahydrate metasilicatewaa si xoog leh cawaaqib xumadoodu, isagoo awood xoog leh oo lagu nadiifiyo, naqdida iyo sareyso meletariga, hortago faddarayn acidic, baabaáysa baruurta iyo saliid, deflocculating inay ka imanba. Waxa bedeli kara STPP in loo isticmaalo soo saaridda ee saabuunta wax ku ool ah oo Faydi miridhku waayo, biraha, yareynta wasakhda deegaanka, ka hortagga daxalka for biraha (zinc, aluminium, iwm). Sidaa darteed, pentahydrate sodium metasilicate waxaa si balaadhan looga isticmaalo soo saaridda of noocyo kala duwan oo saabuun, loo isticmaalo sida Faydi miridhku waayo, biraha, shiidi qalabka dhoobada, wakiilka deinking waraaqaha, dyeing iyo kaabayaal daabacaadda saliidda warshadaha dharka ka saareen, oo sidoo kale loo isticmaalaa sida wax ceeriin for wakiilka flameproofing, wakiilka dayactirka caag ah, wakiilka haynta biyaha, iwm Waxaa loo adeegsaday in wakiilada biyaha yareeyo, pentahydrate sodium metasilicate waa ay awoodaan in ay dadka dhexgalaan hydrones dheeraad ah si ay u qoyaan si fiican saamayn nuugista
