Studies on Rubber (Hevea brasiliensis) Trees Exist Plant Type after Planting and Available Tapping Tree of Rubber Plantation in China
Existing plant types of rubber tree after planting and available tapping tree were investigated, and there were about 28 rubber plantations with different tapping years of 8 varieties “CATAS7-33-97”, “CATAS8-79”, “CATAS7-20-59”, “PR107”, “RRIM600”, “GT1”, “INA873”, “93-114” in South China. The results showed that there were six kinds of existing plant types of rubber tree after planting of rubb...
متن کاملSand – rubber mixtures ( large rubber chips )
Mixtures of small rigid sand particles Ds and large soft rubber particles Dr are prepared at different volume fractions and tested to investigate their small-strain and zero-lateral strain responses (Dr /Ds & 10). Both data sets are simultaneously gathered in an oedometer cell instrumented with bender elements. Data are analyzed in the context of mixture theory and with the aid of numerical sim...
متن کاملHyperelastic Material Models of Rubber and Rubber-like Materials
ABSTRACT The variety of applications of rubber-like materials in different industrial areas is enormous. In the automotive industry rubber is utilized in tires, as engine and door seals, whereas in aerospace industry rubber rings are used in fuel systems. In other engineering fields, rubbers have been used in conveyor belts, meteorological balloons and vibration isolation bearings or shock and ...
متن کاملRubber production in guayule: determination of rubber producing potential.
Optimum conditions for the rapid, efficient, nondestructive determination of rubber producing potential in guayule (Parthenium argentatum) were established. The rubber producing potential may be defined as the ability of the plant material to synthesize rubber from a precursor under specified conditions. To achieve this, stem slices taken from the first 5 centimeters of branches were incubated ...
متن کاملInfluence of Rubber Size on Properties of Crumb Rubber Mortars
Studies on the properties and applications of rubber cement-based materials are well documented. The sizes of rubbers used in these materials varied. However, information about the effects of rubber size on the properties of rubber cement-based materials, especially pore structure, mechanical strengths, and drying shrinkage properties, remains limited. Three groups of rubber with major particle...
