Dab tsi yog hydrated precipitated silica ua los ntawm?
Hydrated Precipitated Silica yog ib daim ntawv ntawm amorphous silica uas yog tsim los ntawm nag lossis daus ntawm silica compound los ntawm kev daws teeb meem raws li kev hloov kho tshuaj thiab dej. Cov khoom pib rau hydrated precipitated silica ntau lawm feem ntau yog sodium silicate tov, uas yog reacted nrog ib tug acid kom yield ib precipitated silica. Lub resulting silica yog ces ntxuav thiab qhuav kom tshem tawm tej impurities thiab dej ntau dhau, thiab tom qab ntawd raug mus rau kev ua ntxiv los hloov nws cov chemistry nto.
Cov qauv tshuaj ntawm hydrated precipitated silica nws txawv nyob ntawm qhov kev hloov kho tshwj xeeb uas siv, tab sis nws feem ntau muaj ib lub network ntawm siloxane thiab silanol pawg. Lub amorphous xwm ntawm hydrated precipitated silica txhais tau hais tias nws tsis muaj ib tug zoo-txhais siv lead ua qauv, tab sis es tsis txhob muaj ib tug ntom, irregular packing ntawm silicon thiab oxygen atoms.
Hydrated precipitated silica yog siv nyob rau hauv ntau yam kev lag luam daim ntaub ntawv, nrog rau raws li ib tug reinforcing muab tub lim nyob rau hauv roj hmab thiab yas khoom, raws li ib tug anti-caking tus neeg saib xyuas nyob rau hauv cov zaub mov thiab tshuaj, thiab raws li ib tug thickening neeg sawv cev nyob rau hauv cov khoom siv tu tus kheej. Nws cov khoom sib xyaw ua ke tshwj xeeb, suav nrog thaj chaw siab, porosity, thiab nto reactivity, ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv.
