Silicagel in beer

Properties:

Beersilica gelisa kind of micro-porestructureofamorphouspowder,apertureof8-16nm,chemicalformulamSiO2•nH2O,insoluble in waterandanysolvents,excepthydrofluoric acidandcaustic, but does notreactwithanyacid,alkali,salt,nontoxic,odorless,nonflammable,non-explosive,strongheat,coldstability, is harmlesstohuman body.Mainlyused in the beerindustry.

Function:

1.beersilica gelwithlargesurface areaand the manysuitablemicro-porousstructure,possiblyin a matter of minutes beer turbidity caused byproteinadsorption,removedbyfiltration,beer180-240-daystorageperiodmay beextended,preventcoldbeercloudy.

2.withoutaffectingbeerfoamandtaste.Silicagel in beerthephysico-chemical propertiesofbeerfoamandtastenothing,practiceproves that Silicagel in beeris the world's safeststabilizer of beer in the beerindustry.

3.improvedfiltrationeffect.Beersilica gelchemicallystable,solublewithoutbeer,theirsurface areaandaresignificantlybetter than those with micro-porousstructure of diatomite,is a verygoodfilterAIDS,auxiliarydiatomitefiltrationcanmakebeermorebrightandclear.

Bluesilica gel

Properties:

Blue silicone is divided into blue rubber indicates agent, and color silicone and blue rubber, appearance for blue or shallow blue glass-like particles, according to particles shape can is divided into spherical and block two species, has silicone adsorption moisture of role, and can with moisture volume of increased, itself color by blue variable purple, last into shallow red, both indicates environment of humidity, also intuitive displayed whether still has moisture role.

Uses:

1.mainlyusedinstruments,instrument,equipmentin the confinedconditionsofmoisture, such asrust.

2.usewithordinarysilica geldesiccant,indicatingdesiccantmoisturedegreesandrelative humidityof the environment.As the silica geldesiccant for package,widelyused in precision instruments,leather,clothing,food,medicinesandhousehold appliances.

SilicaSol

Properties:

SilicaSolis a colloidal solution,odorless,nontoxic, the molecularformulacan beexpressedasmSiO2nH2O.

1.due to colloidalparticles of fine(10-20nm),there is considerablesurface area,particleitselftransparent,does notaffect the coveringsthemselves.

2.lowviscosity,water canpenetratetheplacesareable to penetrate,somixingdispersionandpermeabilityandothermaterialsareverygood.

3.when the silicaSolevaporates,firmlyattached to thesurface of colloidalparticles,particles of Silicon is formedbetweenoxygen,is a verygoodadhesive.

Uses:

1.used as arefractorybinderwithstrongadhesion,hightemperature(1500-1600°c),and so on.

2.used in the paintindustry,canpaint a strong,andresistant to dirt and dust prevention,anti-aging,fire, and otherfunctions.

3.forthin-shellinvestmentcasting,castingshellstrength,highquality finish.Shapemodeling of goodqualitythanwaterglass,instead of ethylsilicatedesigncanreducecostsandimproveoperatingconditions.

4.has a highspecificsurface area of silicaSol,can beused in the manufacture of catalystsandcatalystcarriers.

5.for the paperindustry,asbefore the cellophane paperanti-adherent,photographicpaperprocessingagents,cementbagslipagent.

6.sizingagentsfortextileindustries,itandoilandspinnabilityofprocessedwool,rabbit hair,reducebreakageandpreventflyings,increaseyieldandincreaseeconomic benefits.

7.used as adispersant for silicon steel sheetprocessingagent,picture tubes,skidresistance and floorwax.
