Abstract
The continuous process treatment agent contacted bulk density is about 10 pounds per foot or less3A method of processing a material includes contacting the material with a treatment agent while the material is being transferred from a storage tank to a container in a compacted state. The contacted material may be heated, if desired.
Description
The present invention relates to handle loose density (bulk density) continuously and be equal to or less than 10 pounds/foot with treatment agent
3The method of material.More particularly, the present invention relates to a kind of method, this method comprises: when material was changing in the container under dense state, loose density was approximately equal to or less than 10 pounds/foot
3Material contact with treatment agent; And if necessary, in container to heating with the contacted material of treatment agent.
For the physicals of the composition that improves rubber, coating, tackiness agent, paint and sealing agent and so on, use loose density to be approximately equal to or less than 10 pounds/foot usually
3Material as filler or toughener.The example of these materials has fumigation method silicon-dioxide (fumed silicas), precipitated silica (precipitated silicas), fumigation method aluminum oxide (fumedaluminas), carbon black and aerogel, but is not limited to these materials.
For material is more suitable in specific purposes, usually needs to handle looseness density and be approximately equal to or less than 10 pounds/foot
3Material so that improve their performance.Common known treatment agent comprises liquid, steam, atomized liquid, particulate solid or the like, but is not limited thereto.Usually handle loose density with treatment agent and be approximately equal to or less than 10 pounds/foot
3Material the time, weight ratio is that 1-5 part material is to 1 part of treatment agent.
For example in many application, need to use hydrophobic nature filler or toughener.Therefore, if loose density is approximately equal to or less than 10 pounds/foot
3Material normally hydrophilic, then must handle material, make it become hydrophobic nature.Just as previously discussed, general loose density is approximately equal to or less than 10 pounds/foot
3Hydrophilic materials all handle with treatment agent, make it become the hydrophobic nature material.The example of these treatment agents has silicone oil, silane oil, dimethicone oils and hydrogen fluoride steam, but is not limited to this material.
Usually the loose density of 1-5 part (weight) is approximately equal to or less than 10 pounds/foot
3Material handle with the treatment agent of 1 part (weight).For example, in an embodiment with silane oil treatment fumigation method silicon-dioxide of the present invention, the fumigation method silicon-dioxide of 2-5 part (weight) is handled with the silane oil of 1 part (weight).
Just as previously discussed, loose density is approximately equal to or less than 10 pounds/foot
3An example of material is a fumigation method silicon-dioxide.This material is also referred to as pyrogenic silicon-dioxide, and it is a kind of filler of knowing or toughener, is generally used for improving the physicals of following composition, and these compositions comprise silicon rubber, coating, tackiness agent and sealing agent.Fumigation method silicon-dioxide is gone up substantially by the silica dioxide granule of segmentation and is formed, and its loose density is approximately equal to or less than 5 pounds/foot usually
3Surface-area is usually at 50-400 rice
2Between/the gram.
Loose density is approximately equal to or less than 10 pounds/foot
3Another example of material be precipitated silica.Precipitated silica also is filler or the toughener of knowing, and is generally used for improving the physicals of composition, and these compositions comprise: silicon rubber, coating, tackiness agent and density agent.Precipitated silica is made up of the silica dioxide granule of segmentation basically, and generally its loose density is approximately equal to or less than 10 pounds/foot
3In some applications, need to use the fumigation method silicon-dioxide of hydrophobic nature.Usually handling hydrophilic fumigation method silicon-dioxide with a kind of treatment agent makes hydrophilic fumigation method silicon-dioxide become hydrophobic nature.People's such as Ettlinger United States Patent (USP) 4 for example, 307, No. 023 a kind of treatment process is disclosed, be to use such as the so organic salicide processes fumigation method silicon-dioxide of silicone oil to make this silicon-dioxide become hydrophobic nature, the United States Patent (USP) 4 of Calvin, a kind of method that makes it to become the silicon-dioxide of hydrophobic nature with hydrogen fluoride steam treatment fumigation method silicon-dioxide is also disclosed for 054, No. 689.In order to accelerate the reaction between fumigation method silicon-dioxide and the treatment agent, may need heating.
Usually the processing to fumigation method silicon-dioxide is to carry out with interrupter method in container, and filling fumigation method silicon-dioxide makes fumigation method silicon-dioxide contact with treatment agent then in the container.United States Patent (USP) 4,307 discloses this kind method No. 023.Can use the mechanically mixing device that fumigation method silicon-dioxide is mixed with treatment agent.In the treating processes, container also can heat.The United States Patent (USP) of Razzano also discloses similar method 4,780, No. 108, and this method is: at first the low bulk material is put into mixing vessel, then treatment agent is sprayed on the material, stir material simultaneously intensely.Though at United States Patent (USP) 4,054, in No. 689 disclosed methods, treatment agent can join in the container prior to fumigation method silicon-dioxide, still interrupter method of this patent disclosure.
Existing the contact with material in container with treatment agent handled loose density and is approximately equal to or less than 10 pounds/foot
3The method of material has a lot of shortcomings.At first these methods are discontinuous.In order to keep loose density to be approximately equal to or less than 10 ppfs
3Material and the needed ratio of treatment agent, must in container, add the material and the treatment agent of fixed amount.Finished product must be removed from container fully then, and clean container.Add new loose density in batches again and be approximately equal to or less than 10 pounds/foot
3Material and treatment agent restart treating processes.
Another shortcoming of general method therefor is to add the treatment agent device to container and usually occur stopping up.For example, the usually conduct agent is that injection device or other aperture by pipe end adds in the container.These injection devices or aperture can be approximately equal to or less than 10 pounds/foot by loose density
3Material stop up, therefore usually need to clean.
In addition, because common known method all is interrupter method, thereby treatment agent is easy to balling-up in container, perhaps is accumulated on the injection device or the place, aperture.Therefore, injection device or aperture and container must clean up, to remove the treatment agent of balling-up and accumulation.
And for example fruit container heating, the treatment agent of balling-up is easy to catch fire in container with the treatment agent that is accumulated in nozzle or opening part.If excessive treatment agent fails thoroughly to dispose from container, also can cause the danger of catching fire.
Material is contacted with treatment agent handle loose density in container and be approximately equal to or less than 10 pounds/foot
3Another problem of material is to guarantee that whole materials all contact with treatment agent.Just as previously discussed, usually use the mechanically mixing device, try hard to make loose density to be approximately equal to or less than 10 pounds/foot
3Whole materials contact with treatment agent up hill and dale.Owing to the density issue of material, loose density is approximately equal to or less than 10 pounds/foot
3Material be difficult to shift and stir with mechanism.Therefore, the material near the treatment agent feed point will be easy to contact with too much treatment agent.On the contrary, will be easy to contact with very few treatment agent away from the material of treatment agent feed point, be the quality that " excessive contact " or the material of not contact finally all will reduce finished product.
Therefore, purpose of the present invention overcomes exactly and handles loose density with treatment agent and be approximately equal to or less than 10 pounds/foot
3The shortcoming of the currently known methods of material.
Another object of the present invention provides a kind ofly to be handled loose density with treatment agent and is approximately equal to or less than 10 pounds/foot
3The continuation method of material.
A further object of the present invention provides a kind ofly to be handled loose density with treatment agent and is approximately equal to or less than 10 pounds/foot
3The method of material, this kind method can reduce the danger of catching fire significantly.Another object of the present invention provides a kind ofly to be handled loose density with treatment agent and is approximately equal to or less than 10 pounds/foot
3The method of material, in this method, material evenly and fully contacts with treatment agent.
The present invention also has a purpose to provide a kind ofly to handle loose density with treatment agent and be approximately equal to or less than 10 pounds/foot
3The method of material, this kind method need not frequent clean equipment.
To in the explanation that the present invention did, other purposes of the present invention and advantage will be conspicuous below.
