Flake moisture content

Flake Moisture Content. Panels were made with Mondur MR in which the moisture content of the flakes was adjusted to 20 into the press. It is well known that panels cannot be made with phenolic resins at such a high moisture content, since steam pressure blows them apart upon opening of the press. Even to attain 10 moisture content into the press, raw material must be dried to... 

MOR after accelerated aging increases slightly in going from 10 to 20 flake moisture content. The dramatic improvement in thickness swell at the higher moisture content is unexplained. 

The data show the feasibility of making good quality flake-board with Mondur MR at flake moisture content levels as high as 20. ... 

To summarize the mixed hardwood flakeboard study, it can be said that good quality panels were made with Mondur MR at reduced press time, temperature and binder levels and increased flake moisture content vs. the commercial phenolic resin.

The purpose of this presentation has been to illustrate some advantages that are possible in the use of polymeric MDI as a binder for exterior grade wood composite panels. The data given have indicated the potential for savings in press time, press temperature, flake moisture content, resin level and panel density (as compared to conventional phenol-formaldehyde binders) in several types of such panels. 

Particle size, which relates to the surface area available for extraction is obviously one of the most important factors for extraction study. Coats and Wingard noticed that particle size was more influential when the seed grit was being extracted. When oilseed flakes were being extracted, the flake thickness would be a more important factor instead of size of the flakes. Moisture content in oilseed can affect the extraction results. " Optimum moisture content of cottonseed meats for extraction was first reported by Reuther et at to be from 9 to 10%. Work by Arnold and Patel indicated 7 to 10% to be the optimum moisture for cottonseed flakes and very little variation in extraction rate for soybean with moisture content between 8 and 12%. 

The strands move through large dmm dryers which reduce the moisture content to about 2 or 6%, the difference being whether Hquid or dry resin is to be used. Because a desired moisture level into the press is about 6—7% me, a Hquid resin adds water to the system and requires a lower flake moisture than a dry resin. 

Besides the main depolymerization reactions, side reactions should also be considered in the kinetic description of a PET recycling process. This is emphasized by the results obtained from a PET extrusion model [85] shown in Figures 2.19-2.23. The complete set of reactions summarized below in Table 2.10 have been used, but shear effects have not been taken into account. Chain degradation, accompanied by a significant reduction of intrinsic viscosity, occurs even within residence times of a few minutes. Carboxyl end groups, vinyl end groups and acetaldehyde are formed in amounts depending on residence time, temperature and initial moisture content of the PET flakes. 

It is obtained either as a liquor or as flake material of approximately 20% moisture content, and for use as an accelerating admixture is normally supplied as a 33-35% solution. 

This method is used for determining the moisture content of small grain or flake propints. Single,-double or triple base proplnts can be used. The principle of the method is measurement of the current required for electrolysis... 

In the application of the gaseous mode of addition, both of the procedures described above gave good results as shown by the examples given in Table II. Moisture content of the flakes was an important parameter since it controlled concentration of reactive species in the aqueous phase. 

Little previous work has focused directly on the impact of water content on the formation of pyrazines. Koehler and Odell (19) specifically chose a solvent system of lower water content for their stutfy Maga and Sizer (2Q) investigated the effects of initial moisture content and temperature of extrusion on the formation of pyrazines in potato flakes. 

Technical flaked sodium chlorite contains some impurities, including sodium carbonate, which reacts with chlorine and thereby reduces the efficiency of the reaction. The relative humidity and the moisture content of the sodium chlorite also affect the efficiency of the process. Since an aqueous solution is used as a metering fluid, considerable moisture will be present. For these reasons the method described here is considered to be only about 90% efficient, based on the metered chlorine.
