摘要： The invention pertains to a ballistic-resistant moulded article comprising a compressed stack of sheets comprising high molecular weight polyethylene tapes, the direction of the polyethylene tapes within the compressed stack being not unidirectionally, wherein at least part of the tapes have a width of at least 2 mm and a thickness to width ratio of at least 10:1 and a density of at most 99% of the theoretical tape density. The moulded article is based on tapes which have a density below the theoretical density of the tapes. The use of low-density tapes is believed to contribute to the ballistic performance of the panel.

摘要： The invention pertains to a method for dosing a powder into a kneader, whereby the powder is fed via a feeder-mechanism into a feeding hole of the kneader, whereby powder falls from an additional feeding device of the feeder-mechanism into one of at least 4 segments of a rotary valve of the feeder-mechanism or reverse.

摘要： A ballistic resistant article is presented comprising a plurality of fibrous layers, each of said layers comprising a network of fibers, wherein the fibers have a strength of at least 800 mN/tex (1100 MPa) according to ASTM D 7269-07 and a matrix material, wherein the matrix material comprises a mixture comprising: at least one styrene butadiene random copolymer resin, and at least one tackifier. Compared with an article of the same construction but with a matrix material without a tackifier the article according to the invention comprises a higher adhesion between the fibrous layers both in the unaged and aged state and a lower water pick up after water soak. The article additionally comprising a plate of metal or ceramic exhibits minimal or even no delamination of the fibrous layers after ballistic attack. In contrast an article of the same construction but with a matrix material without the styrene butadiene random copolymer resin exhibits (very strong) interior delamination of the fibrous layers and the article of the same construction with the styrene butadiene random copolymer resin, but without the tackifier as the matrix material exhibits light delamination.

摘要： The invention pertains to a method of increasing the sulfuric acid concentration of a first aqueous sulfuric acid solution with a sulfuric acid concentration of 82-89% to a concentrated sulfuric acid solution with a sulfuric acid concentration of at least 90%, comprising the steps of evaporating water from the first aqueous sulfuric acid solution in an evaporator vessel to the concentrated sulfuric acid solution, pumping around a mixture of the first aqueous sulfuric acid solution, part of the concentrated sulfuric acid solution, a second aqueous sulfuric acid solution, and hydrogen peroxide through an enameled piping system comprising the evaporator vessel and one or more heaters and pumps, which piping system is operating at a temperature of at least 180°C, characterized in that the sulfuric acid concentration of the second aqueous sulfuric acid solution is at least 90%.

摘要： The invention pertains to a method for spinning and washing aramid fiber and for recovering sulfuric acid, using a spinning unit and a sulfuric acid recovery unit, comprising the steps: a) spinning an aramid polymer from a sulfuric acid spin dope to a yarn and coagulating the yarn in a coagulation bath having an inlet for water or diluted sulfuric acid and an outlet for sulfuric acid enriched water; b) washing the yarn with water to obtain washed yarn and washing water containing 0.5-20 wt.% sulfuric acid; c) recycling the sulfuric acid enriched water and optionally the washing water to the sulfuric acid recovery unit; d) increasing the sulfuric acid content of the recycled sulfuric acid enriched water, and optionally the washing water, by evaporation to obtain 20 to 98% sulfuric acid and water; e) mixing the 20 to 98% sulfuric acid with oleum to obtain 98-105% sulfuric acid; f) recycling the 98-105% sulfuric acid to the spinning unit for use as sulfuric acid spin dope.

摘要： Process for producing a plurality of high strength, high modulus aromatic polyamide filaments comprising the steps of - extruding an acid solution containing at least 15 % by weight of an aromatic polyamide through linearly arranged orifices in a spinneret thus providing a warp of filaments - passing the warp of filaments through a layer of non-coagulating fluid into a coagulation bath and subsequently - passing the warp through a spin tube, the spin tube having an elongated cross section with at least two opposite sides being parallel to the filament warp with the length of these sides being at least as long as the width of the filament warp - jetting additional coagulating liquid at a constant flow rate about the filaments in a downward direction at an angle between 15° and 75° with respect to the filaments, - the jetted coagulating liquid moving downward with the warp of filaments through the spin tube at a velocity of about 50% to 100% of the velocity of the filaments, the coagulating liquid being jetted through a jet channel from either one side of the spin tube which is parallel to the filament warp, the jet channel having at least the same width as the filament warp
