Abstract: A system and method for preparing epoxy chloropropane is provided in that by coupling three stages of high gravity reactors, the product epoxy chloropropane and water vapor are distilled from a reaction system in form of an azeotrope by adopting a water vapor steam stripping method. Further, by combining the azeotrope with the multiples stages of high gravity reactors, the gas phase mass transfer and the liquid phase mass transfer of the azeotrope are improved aiming at the features of the azeotrope in the reaction system, thus making the overall conversion rate higher. In addition, by combining steam stripping and high gravity, dichloropropanol and alkali solution are rapidly mixed for mass transfer, and the product epoxy chloropropane is rapidly distilled from the reaction system in the form of the azeotrope, such that the reaction proceeds continuously towards the direction of producing epoxy chloropropane, thus significantly improving the conversion rate.

Abstract: Provided are a composite material and a preparation method therefor. The composite material comprises: a base layer; a first plant fibre fabric located on the upper surface of the base layer; optionally, a second plant fibre fabric located on the lower surface of the base layer; and resins present in each layer. The composite material has a decorative performance and an improved mechanical performance.

Abstract: The present disclosure provides a plant fiber textile, a laminate with the plant fiber textile and a fabricating method of the laminate. The plant fiber textile has a matrix resin and continuous plant fibers distributed within the matrix resin. The plant fibers are subjected to a surface modification pretreatment including a coupling treatment with a coupling agent and/or a fire retardation treatment with a fire retardant. The laminate has a stack structure including a layer of the plant fiber textile and at least one layer selected from a group consisting of following layers: glass fiber, aramid fiber or carbon fiber non-woven cloth or textile, preferably distributed within the matrix resin; polymer fiber non-woven cloth or textile, preferably distributed within the matrix resin; or polymer foam or rubber material.

Abstract: A tonneau cover system includes a cover assembly coupled to first and second side rails. The cover assembly includes a cover disposed over and coupled to a frame, a latch mechanism coupled to the frame and having a catch biased toward a latch position to secure the cover to the first side rail and retractable to an unlatch position to release the cover from the first side rail, a release device coupled to the frame and latch mechanism and actuatable to move the catch to the unlatch position, and an adjustment mechanism coupled to the latch mechanism. The adjustment mechanism has a first portion coupled to the catch and a second portion interacting with the first portion to adjust a vertical position of the catch relative to the frame transverse to a width-wise axis defined between the side rails, with the first and/or second portions forming a sloped profile.

Abstract: A tonneau cover system includes a plurality of panels coupled to first and second side rails. The panels include a first panel, a second panel, a third panel, and a spacer bar with the spacer bar fixed to the side rails. The first panel pivots relative to the spacer while the spacer remains fixed to the side rails. The third panel pivots relative to the second panel to permit the third panel to be located over the second panel while the spacer remains fixed to the side rails to define an intermediate folded position. The cover further includes a hinge assembly mounted between the second panel and the spacer to enable the second and third panels to pivot relative to the spacer as a unit from the intermediate position to a final position located at least over the spacer bar while the spacer bar remains fixed to the side rails.

Abstract: A tonneau cover system for covering a space. The system includes a frame having rails. A cover is disposed over the frame for covering the space. A block, a receiver, an anchor and a latch are all coupled to the frame. A mechanism is disposed between the block and the receiver and provides adjustment to the frame by moving the receiver, the anchor and the latch as a unit between an initial adjustment position and a final adjustment position. The mechanism also provides tension to the cover when the latch is engaging the frame.

Abstract: A tonneau cover system for a vehicle having a cargo box includes a striker which is adapted to be fixed to the cargo box along with a cover disposed over the cargo box when the cover is in a closed position. Moreover, the cover includes a latch mounted to the frame. The latch engages the striker when the cover is in the closed position. The cover further includes a link which extends from the latch along the frame and a handle coupled to the latch in order to move the latch into a released position which disengages the striker. Finally, the cover includes a coupler which is coupled to the handle. The coupler moves from a first position to a second position and responds to movement of the handle with the link moving relative to the frame in order to facilitate movement of the latch into the released position.

Abstract: A roll-up cover assembly includes a cover assembly comprising first and second side rails and front and rear bumpers, as well as a cover, wherein a lower portion of an inner side of the first side rail is provided with a slideway, an adjustment base, an adjustment screw, an adjustment knob, a receiver; the adjustment base is fixed inside the first side rail and can not be moved; the adjustment base is provided with the adjustment knob thereon, the adjustment screw passes through the adjustment base and the adjustment knob, and an end part of the adjustment screw is snap-fixed into a groove on the receiver; the receiver is a separated-type structure, wherein both of the upper and lower portions are fixed onto the slideway, and when the adjustment knob is turned, the adjustment screw produces a displacement and drives the receiver to slide within the slideway.
