Dawb Silica Gel

Lus piav qhia luv luv:

Silica gel desiccant yog cov khoom siv adsorption muaj zog heev, uas feem ntau yog npaj los ntawm kev ua haujlwm ntawm sodium silicate nrog sulfuric acid, kev laus, kua qaub npuas thiab cov txheej txheem tom qab kho. Silica gel yog cov tshuaj amorphous, thiab nws cov tshuaj formula yog mSiO2. nH 2 o. Nws yog insoluble nyob rau hauv dej thiab tej yam hnyav, uas tsis yog-tshuaj lom thiab tasteless, nrog rau cov tshuaj ruaj khov, thiab tsis hnov ​​​​mob nrog ib yam khoom tshwj tsis yog lub hauv paus muaj zog thiab hydrofluoric acid. Cov tshuaj lom neeg muaj pes tsawg leeg thiab cov qauv ntawm lub cev ntawm silica gel txiav txim siab tias nws muaj cov yam ntxwv uas ntau lwm yam khoom zoo sib xws yog qhov nyuaj los hloov. Silica gel desiccant muaj kev ua haujlwm siab adsorption, zoo thermal stability, ruaj khov khoom, siab mechanical zog, thiab lwm yam
