Characteristics：
Silica SOl is a kind of colloid which iS formed by nm—grade particles SiO，dispersed in water．With bigger specific
surface of Si02 colloid particles，silica sol is widely used in precision casting，papermaking，textile and paint industry
as inorganic adhesive．and is also used as catalyst and skidproof avent．
Traditional alkali/acid silica SOl have been used in precision casting．papermaking and paint industry for many
years．Silica S01 with special specifications iS needed recently with the improvement of world technology．In order
to meet this market，Oingdao Hai Yang Chemicals CO．，Ltd has developed a series of new silica SOl products．
Application
Use：
1．JX IS a kind of silica SOl of small sized particle diameter．Apart from characteristics of ordinary alkall silica
sol，JX has small sized particle diameter，big specific surface，SO it has the advantages of good smooth finish and
high precision in size，compared with ordinary alkali silica sol．It also has the special usage in storage battery
industry．
2．JA is a kind of silica sol with ammonium as its stable agent．For ordinary silica sol，the exist of Na+is a
disadvantage when at high temperature or with the exist of catalyst or when is used directly as catalyst．Thus JX
has its advantage without Na+，compared with ordinary silica s01．
3．ZA is a kind of neutral silica sol．Compared with ordinary alkali silica sol，ZA has no need to adjust PH
value to maintain its stability．So ZA is practical in coating，especially under high temperature in ceramics and
catalyst．
4．JK is a kind of silica sol of high drying speed．Compared with ordinary silica sol when used in precision
casting，JK has the advantage of shorter dry time，1/2—1/3 of the ordinary time．Furthermore，it has improved its
high temperature—resistant performance．
