Abstract: An improved structure of paper cup, which comprising: a cup body and bottom; the cup body is designed with an annular side wall, and an outward folded arced cup edge is set on the ring edge at one end; the annular side wall is provided with an annular side wall mated with the annular side wall of the cup body far away from the cup edge to form holding space; the cup body and bottom form a holding space; particularly, an inflexed edge is formed at the annular side walls where the cup body is abutted with the cup bottom, thus reducing the height of the annular side wall for the mating of the cup body and bottom; when a large number of paper cups are stacked, the gap between cups could be reduced, thus increasing the storage amount and saving the storage and transportation cost.

Abstract: An improved composite cup structure, which comprising: an inner plastic cup and an outer paper cup; of which the composite cup is manufactured from paper and plastics by a ratio of 7:3; the rims of both inner plastic cup and outer paper cup are provided with outwards curled edges, in particular, the curled edge of the inner plastic cup is slightly larger than that of the outer paper cup, and a flat surface is formed on the top; besides, an extension sheet of any shape is formed on the curled edge towards the cup bottom; when the inner and outer cups are overlapped, the curled edge of the inner plastic cup could cover the curled edge of the outer paper cup, thus forming a heat-insulating, leak-proofing composite cup of excellent strength; the extension sheet contributes to the separation of inner and outer cups for classification and recycling.

Abstract: An insulation paper cup, which mainly comprises an inner cup, intermediate layer and external cardboard; the inner cup is provided with a bottom at one end and an opening at the other end, and the opening is fitted with a flange; the intermediate layer made of PLA foaming materials is arranged at periphery of the inner cup, while the external cardboard is adhered onto the intermediate layer and printed with letters or patterns; with this combined structure, the insulation paper cup features excellent heat/cold insulation and non-condensing effect; due to the characteristics of PLA such as: natural property, non-toxicity, recyclability and environmental friendliness, the product can be recycled without causing any disposal problems and any burden on the environment.

Abstract: A recycling and treatment method of mono silicon's cutting waste liquid, which includes the following steps: 1. treat the waste liquid with diluted hydrochloric acid, then stir into an easy-to-flow mixture; 2. heat up the mixture for solid-liquid separation, such that water and polyethylene glycol are evaporated, condensed and dehydrated to recover the polyethylene glycol, and obtain coarse solid mixture of silicon carbide and silicon; 3. obtain the secondary solid mixture of silicon carbide and silicon by secondary cleaning of the coarse solid mixture with water; 4. recycle silicon and silicon carbide by treatment with the mixed acid solution of HN03+HF. This method features simplicity, ease of operation, low cost and high recycling rate, with the overall yield of cutting waste liquid up to 26-46%; moreover, the quality of recycled products can reach or approach the standard indexes, so they can be directly used in solar battery production.

Abstract: A spray blended emulsifier comprises: a blending kettle, a feeding tank, a sprayer, a residuum pump, a thermal resistance probe, a tee valve and discharge tube; the charge pipe underneath said feeding tank is mounted on the upper cover of the blending kettle, and extended into the blending kettle. The sprayer contains a spraying channel and a guide plate; the spraying channel contains a nozzle inlet, a turbulent path, a blending chamber and a nozzle outlet connected in series; the nozzle inlet is of a funnel pattern. The spray blended emulsifier is structurally characterized by that, spraying channel and guide plate are mounted into the sprayer, a turbulent path is placed in the spraying channel, and the liquid flow has a Reynolds number larger than 3000.

Abstract: Insulating paper container including an inner paper cup and an outer paper cup. The inner cup includes a base and double bulge rings and the inner side of outer cup is coated evenly with chemical laminating agent and foaming agent. Space between the two bulge rings allows foaming when the inner cup is placed within the outer cup. The two bulge rings stabilize the structure of the outer cup hence to form a complete insulating paper container unit, and provide a foam insulating layer between the inner and outer cups by heat activating the chemical laminating agent and foaming agent. Therefore the present invention offers a safe and insulated insulating paper container.
