The disclosure provides a method and a system for adjusting an irradiation angle of a lamp and a lamp with adjustable irradiation angle. The lamp includes a plurality of infrared receivers and a driving motor. The method comprises: receiving an infrared signal from a remote controller via the plurality of infrared receivers; determining an irradiation angle adjustment value of the lamp based on a plurality of infrared signal intensity values of the plurality of infrared receivers; adjusting an irradiation angle of the lamp via the driving motor based on the irradiation angle adjustment value. In the technical scheme provided by the example of the disclosure, when the irradiation angle of the lamp needs to be adjusted, the irradiation angle of the lamp is controlled only by operating the remote controller.

Disclosed in the present invention is a polyether polyol refining method, comprising (1) neutralising or diluting crude polyether polyol to obtain a mixed solution; (2) flowing the mixed solution through a hydrophilic medium to aggregate same into a first density phase liquid and a second density phase liquid, the first density phase liquid being an aqueous solution containing alkaline metal ions and/or alkaline earth metal ions, and the second density phase liquid being polyether polyol; and (3) allowing the first density phase liquid to settle and separating same from the second density phase liquid to obtain refined polyether polyol. In the present refining method, using the hydrophilic medium for one-step removal of the alkaline ions and water in the polyether polyol simplifies the treatment steps, increases treatment efficiency, and can prevent polyether polyol loss; the obtained polyether polyol has low alkaline ion content and little odour. Also disclosed in the present invention is a polyether polyol refining apparatus, comprising a mixing unit and a separating unit, and being capable of refining polyether polyol with low alkaline ion content and little odour.

A wake-up light includes a shade, a housing, a power driver, a controller, a light source, and a timer. The power driver, the light source, the controller, and the timer are installed in a space enclosed by the shade and the housing; the power driver is externally connected to an alternating current, and supplies power to the timer and the light source; the timer is configured for real-time timing; the controller is connected to the light source and the timer; the controller receives timing information of the timer; when a first time set by a user is reached, the controller sends a light-source light-up signal to the light source so that a light intensity of the light source is gradually increased; and when a second time set by the user is reached, the controller sends an impulsive light signal to the light source so that the light source uninterruptedly emits impulsive light.

Application of a Mannich base in a flame-retardant polyurethane material is provided. The Mannich base has a structure represented by a formula (I). In the Mannich base, flame-retardant groups, i.e., halogens are introduced at the second, fourth and sixth positions of a phenyl group, and flame-retardant elements, i.e., halogens and nitrogen are introduced into synthesized polyether polyol, giving the synthesized polyether polyol good flame retardance. The amount of active hydrogen in the Mannich base is small so that occurrence of side reactions during the synthesis of the polyether polyol is reduced, and the viscosity of the flame-retardant polyether polyol is lowered. Due to autocatalytic performance of tertiary amido in the flame-retardant polyether polyol, use of a catalyst can be reduced and even avoided during the synthesis. A preparation method of the Mannich base is also provided.

A flame-retardant polyether polyol is provided, including a Mannich base and an epoxide. The epoxide is selected from ethylene oxide, propylene oxide and butylene oxide. The Mannich base has a structure represented by a formula (I). In the Mannich base, flame-retardant groups, i.e., halogens are introduced at the second, fourth and sixth positions of a phenyl group, and flame-retardant elements, i.e., halogens and nitrogen are introduced into synthesized polyether polyol. The amount of active hydrogen in the Mannich base is small so that side reactions during synthesis of the polyether polyol are reduced, and the viscosity of the polyether polyol is lowered. A flame-retardant polyurethane material is also provided, synthesized from raw materials comprising the above-mentioned flame-retardant polyether polyol and an isocyanate. Due to autocatalytic performance of tertiary amido in the flame-retardant polyether polyol, use of a catalyst can be reduced and even avoided during the synthesis.
