103 results about "APAO" patented technology

Amorphous Poly-alpha-olefins (APAO) are produced by (co-) polymerisation of α-olefins, e.g. propylene or 1-butene with Ziegler-Natta catalysts. The (co-)polymers have an amorphous structure which makes them useful for the production of hot melt adhesives.

Comprehensive integrated testing protocol for infant lung function

InactiveUS20090131811A1Highly repeatable robust measurementRespiratory organ evaluationSensorsNitrogen gasSlow vital capacity
A Comprehensive Integrated Testing Protocol (CITP) incorporates precise measurements of the dynamic and the static lung volumes and capacities at V30 for routine infant lung function testing. The static functional residual capacity (sFRC) in infants is measured after a short hyperventilation induces a post-hyperventilation apnea (PHA) that abolishes the infant's breathing strategies and creates a reliable volume landmark. A measurement of the sFRC is then obtained by inert gas washout; e.g., by measuring the volume of nitrogen expired after end-passive expiratory switching of the inspired gas from room air to 100% oxygen during the PHA. A true measurement of the total lung capacity (TLC) is obtained from the sum of (1) the passively exhaled gas volume from a Pao plateau of 30 cm H2O through a pneumotachometer (PNT) by integrating the flow signal to produce volume, which is the inspiratory capacity (IC), and (2) the sFRC. From intrasubject TLC and residual volume (RV), the difference is a reliable estimate of the slow vital capacity (SVC). Similar measurements may be obtained with a fastened squeeze jacket for comparison. Actual airway opening pressure (aPao) is measured during a 0.20 s airway occlusion after halting the inflating airflow and prior to activating the jacket inflation. An open mouth is maintained during forced expiration in order to generate an oronasal instead of a forced expiration.

Hot melt adhesive and preparation process thereof

The invention belongs to a hot melt adhesive and a preparation process thereof. The hot melt adhesive is composed of naphthenic oil, white oil, EVA (Ethyleno Vinyl Acetale), APAO (Amorphous Poly Alpha Olefin), wax, rosin modified resin, petroleum resin, an antioxidant and an anti-aging agent. The preparation process comprises the following steps: preparing materials at a formula ratio; checking to confirm that no foreign matter exists in a reaction kettle, and starting a switch to heat conductive oil; and putting the naphthenic oil, the white oil, the wax, the antioxidant, the anti-aging agent and the like, heating for 25-35 minutes, putting APAO, EVA and the like after the temperature is increased to 65-75 DEG C, introducing nitrogen in the reaction kettle, heating and stirring for 1-3 hours, putting the rosin modified resin and the petroleum resin after the materials are completely melted, and vacuumizing and stirring until a colloid is uniform and free from bubbles so as to obtain the adhesive. The hot melt adhesive is mainly applied to adhering the materials, such as paper, artworks and coated films; and the hot melt adhesive prepared by the invention is high in adhesive force, high in drying speed, low in energy consumption, good in thermal stability, aging resistant and acid and alkali resistant, and is applied to automatic flow line producing and packaging requirements.

Preparation method of high-temperature-resistant thermoplastic hot melt adhesive for furniture edge sealing

The invention provides a preparation method of a high-temperature-resistant thermoplastic hot melt adhesive for furniture edge sealing, and belongs to the field of hot melt adhesives for furniture edge sealing. The method prepares the high-temperature-resistant hot melt adhesive for furniture edge sealing by rationally designing a ratio of an ethylene-vinyl acetate copolymer (EVA) to an amorphousalpha-olefin copolymer (APAO) to resin to a filler to an antioxidant. The high-temperature-resistant hot melt adhesive for furniture edge sealing provided by the invention has the advantages of no drawing, higher initial adhesion, low odor and better bonding performance, and can meet the requirements for edge sealing of ordinary shaving boards, density boards and laminated wood boards; the hot melt adhesive for furniture edge sealing has better high-temperature resistance, and is suitable for storage and transportation of edge-sealing finished products under higher-temperature conditions (70-90 DEG C), while an ordinary EVA hot melt adhesive for edge sealing can only be used at 50-70 DEG C, so that the method solve the problem that the ordinary EVA hot melt adhesive for edge sealing cannotbe used under high-temperature conditions.
