Filler kaolin clay

Organofunctional silanes are used to promote polymer-to-filler bonding with clay or siHca fillers. Vinyl silanes are used in peroxide-cured wire insulation to promote stronger bonding with calcined clay fillers. Mercapto silanes are used to treat kaolin clay in sulfur-cured compounds. 

The filler is a clay incorporated into the catalyst to dilute its activity. Kaoline [A. 2(OH)2, Si205] is the most common clay used in the FCC catalyst. One FCC catalyst manufacturer uses kaoline clay as a skeleton to grow the zeolite in situ. 

This term is applied to a wide variety of materials known chemically as hydrated aluminium silicates, used as inorganic fillers. China clay (kaolin) shows a slight reinforcing effect treated clays show considerably greater reinforcement.

Layered clay silicates, generally from the intermediate-grained montmorillonite kaolin clay, are often used as filler in plastics and in the production of pottery and other ceramic items. These silicates consist of the silicate sheets held together mostly by the sodium cation with lesser amounts of other metal ions, such as iron, copper, nickel, etc. There are several approaches to open these silicate layers. 

Kaolin clays are naturally occuring sedimentary deposits composed largely of kaolinite mineral. Typical impurities in these deposits are iron oxides, titanifer-ous minerals, silica, feldspar, mica, sulfides and organic matter. The majority of kaolin clay produced in the world is used in the paper industry as coating and filler materials. This mineral also makes an excellent filler, carrier, opacifier and diluent in a variety of industrial products such as paints, plastics, cement, rubber, pharmaceuticals, etc.

Physical methods of separation are preferred to those using chemical reagents or organic solvents. These are the standard methods of separation of minerals. Iron oxides can be recovered magnetically.12 The iron oxide in kaolin clay is removed by high-intensity magnetic separation. The treated clay is used as a filler for paper. Ores can be separated by a variety of methods involving radiation. If the... 

There are basically only three types of platelet-type fillers which can be considered for use in thin barrier films. These are aluminum flake, mica and talc (Table II). Other types of platelets, such as glass, stainless steel or brass flakes and certain aluminum silicate minerals, such as kaolin clay, are either too large in particle size or have too low an aspect ratio to be useful. With these three... 

Apparently, none of WPC manufacturers adds calcium carbonate as a filler in then-products. LDl Composites, which use Biodac that consists of about 25% CaC03 and 25% of kaolin (clay), also did not use individual minerals as fillers. Nevertheless, there are many publications, mainly by suppliers of minerals and university researchers, describing benefits of calcium carbonate in WPCs.

A series of additional filler systems merit brief discussion, not because of their reinforcement qualities but because of their high consumption. These include kaolin clay (hydrous aluminum silicate), mica (potassium aluminum silicate), talc (magnesium silicate), limestone (calcium carbonate), and titanium dioxide. 

The identification of polymers by FTIR is often complicated by the presence of fillers. However for kaolin clay, an FTIR analysis should be able to identify the filler and predict its concentration using a standard curve. The resulting percentage is more reliable than a simple ash, which may change the chemical composition of the filler. 

The ashing of the samples at 500°C produced an unanticipated event. Kaolin clay holds water even when considered bone diy. This water was liberated Irom the clay when it was ashed. Aluminum silicate underwent a partial transformation to aluminum oxide and silicon oxide. Figure 4 is the FTIR spectrum of the ashed material. This raises a problem with simply doing percent filler by ashing when the filler is kaolin clay the results can be 12-20% low based on percent water and degree of conversion. Also, FTIR of the ashed material could be misinterpreted as silicates rather than aluminum silicate.
