Silica la shiiday ee Hydrophilic
Hordhac Badeecada
Silica la shiiday, ama silica pyrogenic, oo ah silica colloidal silicon dioxide, waa budo cad oo aan dabiici ahayn oo aan qaab lahayn oo leh bedka dusha sare ee gaarka ah, cabbirka walxaha aasaasiga ah ee nano-scale iyo uruurinta kooxaha silanol ee dusha sare ee sare (oo ka mid ah alaabada silica). Sifooyinka silica la shiiday waxaa si kiimiko ah wax looga beddeli karaa iyadoo la falgalo kooxahan silanol.
Silica qiiqa leh ee ganacsiga laga heli karo waxaa loo qaybin karaa laba kooxood: silica qiiqa leh ee hydrophilic iyo silica qiiqa leh ee hydrophobic. Waxaa si weyn loogu isticmaalaa warshado badan sida caagga silikoon, rinjiga iyo balaastikada.
Astaamaha ugu Muhiimsan
1, kala firdhis wanaagsan, ka hortagga quusitaanka iyo nuugista wanaagsan.
2, Cinjirka silikoon: xoojin sare, iska caabin sare oo jeexjeexan, iska caabin wanaagsan oo xoqid ah, hufnaan wanaagsan.
3, rinjiga: ka hortagga jabka, ka hortagga degitaanka, hagaajinta xasilloonida midabka, hagaajinta kala firdhinta midabka, hagaajinta dhegdhegga filimka, ka hortagga daxalka, biyaha celinaya, ka hortagga xumbo, ka caawinta socodka, kor u qaadida xakamaynta rheological.
4, Waxaa lagu dabaqi karaa lakab kasta oo rinji ah (dhejin, dahaar, khad) si loo hagaajiyo xasilloonida midabka, loo hagaajiyo kala firdhinta midabka, loo hagaajiyo isku-xidhka filimka, la-dagaallanka daxalka, la-biyo-celin, la-dagaallanka xumbo-ka-hortagga, gaar ahaan xoojinta caagga silikoon, wakiilka dhejiska thixotropic, wakiilka ka-hortagga degitaanka ee nidaamka midabaynta.
5, nidaamka dareeraha ah wuxuu heli karaa dhumuc, xakamaynta rheology, joojinta, ka hortagga hoos u dhaca iyo doorar kale.
6, Nidaamka adag wuxuu hagaajin karaa kor u qaadista, u adkaysta xirashada iyo wixii la mid ah.
7, Nidaamka budada wuxuu hagaajin karaa socodka xorta ah wuxuuna ka hortagi karaa isku-darka iyo saameynta kale. Waxa kale oo loo isticmaali karaa buuxin firfircoon oo sare leh oo loogu talagalay caagga dabiiciga ah iyo kan macmal ah, daawada iyo qurxinta.
