Definitions
- This invention relates to a method of utilising silica soot from the quartz glass production. More specific, this invention is a method for utilising the pure silica soot, which is collected in the off-gas filter in the production of optical fibre raw material quartz glass cylinder ingots.
- the group of fine silica materials consists of micro-silica, precipitated silica and fumed silica.
- Micro-silica stems from the production of silicon metal in electric arc furnaces. It has a specific surface area of approx. 10-30 m 2 /g and is mainly applied in the concrete business.
- the precipitated silica is produced in a hydrometallurgical process, has a specific surface area in the range of 90-600 m 2 /g and is used as reinforcement filler to silicon rubber and plastic as well as filler in paper and paints.
- Fumed silica is produced in a pyrometallurgical process, has a specific surface area in the range of 100-800 m /g and is used as a pseudoplastic and thixotropic property agent in resins, as a rheological property agent in plastisols, to reduce the water absorption of printing ink, viscosity control and thixotropic agent in paints and coatings, as thickener and gelling agent in rechargeable batteries, in chemical-mechanical polishing, as a reinforcing filler in silicon elastomers, as reinforcing and rheological properties agent in joint sealant, in electrophotographic toners and developers as well as in cosmetics, pharmaceuticals and foods.
- Silica soot stems from the production of high purity fused quartz glass for e g the optical fibre industry.
- the first step of the quartz glass produced can be to produce silica soot in a flame hydrolysis process, in which silicon tetrachloride and various volatile reactants are introduced to an oxygen/hydrogen flame.
- the product of this process takes a physical form of fine particles and these are usually designated as silica "soot".
- this silica soot is heated to or slightly above its melting point.
- silica soot particles fuse with one another and create a quartz glass material without voids.
- some of the silica soot particles escape the sintering process trough the furnace off-gas system and must be collected in the off-gas cleansing filter.
- this silica soot, collected in the off-gas filter has mainly been considered as a waste material which has been pelletized and put on the municipal rubbish heap.
- This solution of the waste slurry problem is unfortunate, both from an economical and environmental point of view. Especially when considering that the silicon soot are leftovers from one of the commercially available purest raw material, and thus constitute a valuable material which is well suited to be applied as raw material in a number of industrial applications.
- the objective of this invention is to eliminate the waste disposal by utilising the silica soot as a raw material in other industrial applications.
- Another objective of this invention is to provide a method for using the silica soot as a substitute to fumed and precipitated silica.
- silica soot is a very pure X-ray amorphous silicon dioxide (SiO2) which is physiologically inert.
- silica soot may be utilised as a substitute for conventional fumed silica and/or precipitated silica as an active reinforcing filler and thixotropic agent in a variety of applications.
- Table 1 which compares a set of properties of a conventional fumed silica sold under the name acker HDK® H 15 and silica soot. Both materials have a bright white colour with light reflection above 94%.
- silica soot is a waste material which is very cheap compared to a highly purified raw material such as fumed silica or precipitated silica. And it is fairly obvious that the environment will also benefit when a waste materiel is given the opportunity of being utilised as a raw material in other industrial processes.
- the Silica Soot is a pyrogenic silica with a specific area (BET) of ca 50 m 2 /g.
- BET specific area
- TOTAL 100,00 110,00 Sealants with a total movement capacity of 25% are classified according to their modulus into two types:
- Type HM high modulus tensile modulus E 100 at 23 °C > 0,4 N/mm 2 at - 20 °C > 0,6 N/mm 2
- the tested transparent/opalescent silicone sealant fulfil the requirements of ISO 11600 for high modulus sealants with a total movement capacity of 25 % and is design as: Sealant ISO 11600 F - 25 HM Because of the lower specific area the amount of pyrogenic Silica Soot is about three times higher to have a non sag type sealant. Due to this effect it is possible to incorporate more silica into the sealant.
- the whitish colour of the pyrogenic Silica Soot is suitable for the production of transparent/translucent silicone sealants.
- Acrylic sealants with Silica Soot has been produced and tested according to ISO F/DIS 116600 : 2001 Building construction- Jointing products-Sealants- Classification and requirements in order to find out if the in acrylic sealants widely used pyrogenic silica Aerosil R 972 can be replaced by Silica Soot.
- the Silica Soot is a pyrogenic silica with a specific area (BET) of ca 50 m 2 /g.
- the pyrogenic Silica Soot with a specific surface area (BET) of 47.9 m 2 /g was used instead of a pyrogenic hydrophobic silica Aerosil R 972 with a BET surface area of 110 m 2 /g in a acrylic water-based sealant.
- Acrylic sealants with a total movement capacity of 12,5 % are classified according to their modulus into two types:
- the tested acrylic sealants correspond to a sealant with mainly elastomeric properties.
- the preconditioning was carried out according to method B of DIN EN 28 340.
- Test according to ISO F/DIS 11600:2001 The test of the adhesion and cohesion properties was carried out according to the test conditions described in the test procedures.
- the tested acrylic sealant fulfill the requirements of ISO F/DIS 11600:2001 for elastomeric sealants with a total movement capacity of 12,5 % and is design as: Sealant ISO 11600 F - 12,5 E
- Silicone rubber is often produced from dimethyl-dichlorine-silane, in a process where the chlorine ions are exchanged with oxygen through hydrolysis until the whole material is polymerised.
- a number of additives are added to the liquid material to provide it with the ideal rheological properties and also the necessary mechanical strength as well as a smooth surface.
- additives are among others; filler, plasticizer, adhesion promoter, crosslinker, and cure catalyst.
- Fumed silica e g the above mentioned Wacker HDK® H 15, is the most commonly used filler in silicone rubber. Normally approximately 8-10% fumed silica is added as filler material.
- the silicone rubber is somewhat heavier.
- the additional weight might reduce the price in the market.
- the loss of transparency will make silica soot useful only in coloured silicone sealer applications.
- sealants Another class of sealants is polysulphide rubber sealants, a two component sealant comprising a liquid polysulphide elastomer and a curing agent.
- Such sealants often contain calcium carbonate and have encountered problems with segregation. These problems can be solved by replacing the calcium carbonate filler with silica soot. This is a surprising effect since it is known that conventional fumed silica gives a too large viscosity of the sealant.
- Silica soot has been mixed with water to a slicker in the soot/water weight ratio 1 : 1. The mixture got stiff after a few hours. After nine months it is still set, showing no signs of segregation. A touch with e g a brush brings it back to the fluid state. Left to rest the mixture get stiff again. This indicates that silica soot is an excellent viscosity control and thixotropic agent.
- silica soot from the production quartz glass as a replacement of filler materials in other sealants, such as for instance acrylic sealants, butyl rubber sealants etc., and in other types of products such as for instance urethane prepolymers etc.
