  • Patent number: 9969851
    Abstract: In a method for controlling shrinkage of a composite, a dried hydrophobically modified cellulose-based fiber is exposed to a slow acting resin system having a first curing time. An excess amount of the slow acting resin system is removed to separate out the pre-wetted hydrophobically modified cellulose-based fiber. The pre-wetted hydrophobically modified cellulose-based fiber is mixed with a fast acting resin system to form a mixture. The fast acting resin system has a second curing time that is less than the first curing time. The mixture is molded at a predetermined temperature. The fast acting resin system is cured prior to the slow acting resin system, and the slow acting resin system flows into free space within the curing fast acting resin system prior to the slow acting resin system being cured.

  • Publication number: 20170045398
    Abstract: The present invention discloses a method for measuring an actual temperature of a flame by using all information of a radiation spectrum and a measurement system thereof. The method includes: conducting more theoretical data processing by using energy level structure correction, wherein all information of the radiation spectrum can be used; and by way of a keyboard input manner or a data transmission input manner, acquiring an energy level structure correction parameter, and finally acquiring a more accurate actual temperature value of a measured flame. The method effectively overcomes a defect that the true temperature of the flame can be obtained by only conducting radiance correction through data processing with great calculations when adpted multi-spectral temperature measurement method.
