摘要:
A method of producing a surface modified low hysteresis carbon black (SMLHCB). The method includes treating a surface of a low hysteresis carbon black with from about 0.1 to about 50 wt % of a surface modifier to form the SMLHCB. The surface modifier includes an amino acid and at least one amine group.
摘要:
A surface modified and functionalized carbon black for use in a rubber compound suitable for tire tread compounds which can be described as a surface modified low hysteresis carbon black. The modified carbon black contains a chemical consisting of at least one amine group and at least one thiol group and/or di- and/or polysulfidic linkage. The surface modified low hysteresis carbon black in a representative rubber tire tread compound shows improved rolling resistance, improved wet traction, and improved or maintained abrasion resistance, being superior to compounds containing N234 carbon black or silica. The improved tire rolling resistance obtained by using a compound containing a surface modified low hysteresis carbon black is highly desirable for reduced CO2 emissions, reduced pollution, sustainability, and protection of the environment.
摘要:
Non-ASTM low hysteresis carbon blacks chemically treated, and surface coated with a compound comprising at least one amine group and at least one thiol group, and/or di- and/or polysulfidic linkage. When compared with a standard ASTM grade compound, the disclosed surface modified low hysteresis carbon black compound shows improved rolling resistance, wet traction, and DIN abrasion, comparable to silica compounds.
摘要:
A filling spout assembly for filling bags with air-fluidized particulate solids comprising an air evacuation tube concentrically and slideably mounted within the filling spout and passing through the bottom of the solids hopper; a circular valve mounted on the air evacuation tube to open and close the filling spout to the flow of solids. The preferred embodiment includes a sealing means, also mounted on the air evacuation tube, for sealing off the flow of air into the filling spout while the valve is in its forward position during the filling of the bag.
摘要:
Apparatus, for printing information on a paper bag, featuring a mechanism for raising a printing arm after a bag is printed, pivoting the arm in an arc to another position, and then actuating the arm toward an ink pad so that the printing plate contacts the pad. The cycles of operation are preferably sequentially timed with the operation of a device for stripping one bag at a time from a stack of bags.
摘要:
Relatively large particle-size, low structure carbon black is manufactured by applying primary heat in conventional fashion to a hydrocarbon oil feedstock and then applying secondary heat in the form of hot combustion gases introduced into the reactor downstream of the primary reaction zone. The flow of these secondary combustion gases is longitudinal with respect to the axis of the reactor and is introduced into the reactor in a plurality of streams directed in downstream flow in close proximity with the outer periphery of the secondary reaction zone. The reactor is of enlarged diameter just downstream of the point of introduction of the secondary combustion gases in order that the concentration and linear downstream velocity of the combustion products is essentially unaltered.
摘要:
A wire hanger particularly designed for hanging a bag filter is of substantially triangular configuration with two overlapping loops extending beyond the apex of the triangle. The overlapping loops define an eye by which the hanger is supported. Each loop is slideable on the other so that the hanger also functions as a tension spring.
