Silica gel sifooyinka walxaha, farsamada farsamaynta iyo codsiga
Qalabka jelka silica wuxuu leeyahay sifooyinka waxqabadka sare ee adsorption, xasilloonida kulaylka wanaagsan, xasiloonida kiimikada, xoogga farsamada sare iyo wixii la mid ah, waxaana si ballaaran loo isticmaalaa naqshadeynta alaabta. Maaddadana waxaa loo beddelay jel silica gaar ah si loo waafajiyo shuruudaha shaqeynta ee alaabada kala duwan, sida iftiinka, ion taban, midabaynta iyo sifooyinka kale.
Hordhac jel silica
Silica jel waa nooc ka mid ah walxaha adsorption aad u firfircoon, waxay ka tirsan tahay walaxda amorphous, taas oo ka kooban polysiloxane, saliid silikoon, silica madow (silica), wakiilka isku-xidhka iyo buuxinta, iwm, qaybta ugu muhiimsan waa silica. Aan ku milmin biyaha iyo wax kasta oo dareere ah, aan sun ahayn oo aan dhadhan lahayn, kiimiko ahaan deggan, marka lagu daro alkali xooggan, hydrofluoric acid kama falceliso walax kasta. Noocyada kala duwan ee jel silica waxay sameeyaan qaabab kala duwan oo micropore ah sababtoo ah hababka wax soo saarka ee kala duwan. Halabuurka kiimikada iyo qaab-dhismeedka jirka ee silica jel ayaa go'aaminaya in uu leeyahay sifooyin badan oo kale oo la mid ah kuwaas oo ay adag tahay in la beddelo: waxqabadka sare ee xayeysiinta, xasilloonida kulaylka wanaagsan, sifooyinka kiimikada deggan, iyo xoogga farsamada sare.
Kala soocida jel silica
Silikoon waxaa loo kala saari karaa iyadoo loo eegayo sifooyin kala duwan:
Sida laga soo xigtay halabuurka waxaa loo qaybin karaa: hal qayb iyo laba qaybood oo silica ah.
Sida laga soo xigtay heerkulka vulcanization waxaa loo qaybin karaa: vulcanization heerkulka sare iyo heerkulka qolka silikoon vulcanization.
Marka loo eego qaabka sheyga ayaa loo qaybin karaa: dareeraha iyo jel silica adag.
Marka loo eego falcelinta vulcanization-ka waxa loo qaybin karaa: Nooca falcelinta uumiga, nooca falcelinta ku darista platinum iyo nooca isku-darka peroxide.
Sida laga soo xigtay qaabka ugu weyn ee silsiladda waxaa loo qaybin karaa: jel silica saafi ah iyo jel silica wax laga beddelay.
Sida laga soo xigtay sifooyinka sheyga waxaa loo qaybin karaa: nooca iska caabinta heerkulka sare iyo hooseeya, nooca anti-static, saliid iyo caabbinta dareeraha, nooca korantada, nooca isbuunyada xumbo, nooca caabbinta jeexjeexyada xoogga sare, nooca ilaalinta dab-demiska, nooca qallafsanaanta hoose .
