tensile product
1.High molecular weight biodegradable poly(hexane-succinate) was synthesized by direct polycondensation from succinic acid and 1,6-hexanediol,the chemical structure was identified by FTIR and ~1H-NMR,the intrinsic viscosity was measured by Ubbelohde viscometer,the melting point was determined by DSC,and the tensile strength was 30.9MPa,the elongation at break was 869.5%,in the synthesis procedure high molecular weight of product(Mn=46503) was obtained with the yield of 95.5%.
2.The characteristics of structure and grain, yield strength - ultimate tensile strength (YS-UTS) ratio, and elongation of 2.0~12.7 mm steel Q345B strip produced by CSP process (71 mm cast slab) and conventional process (250 mm cast slab) have been analyzed by quantimet and statistic of product mechanical properties.
3.Using silicon dioxide, magnesia, aluminum hydroxide to react with sulfonic acids, color fixatives under standard proportioning, through curing and drawing into thread-like form, this product is made with mechanical twisting as per specific speed and number of strands after drying treatment, featruing a certain tensile strength.
4.The Company product characteristics : good withstand high temperatures, low temperature performance, longterm use in 80~+250 again : chief climate ageing nature of refractory Otherwise, the highoxygen index, nonabsorbent, chief radiation excellent, if longterm exposure in the atmosphere, surface and the performance of its fundamental unchanged; Kai Jun good performance, high voltage resistance; Excellent resistance to corrosive, Almost any solvents may show in strong acid aqua regia, light oxidation sodium strong base, strong agent five fluorinated uranium are not corrupted; good resistance to abrasion , static friction coefficient is the smallest plastic, since lubricant fine performance, the surface is not quite apparent; tensile strength good.
