A process for producing quick-frozen Chinese yam includes soaking in disinfectant liquid to kill bacteria, peeling, cutting into blocks, soaking in color protecting liquid for maintaining color, soaking in disinfectant liquid to kill bacteria again, milling into particles, filling in plastic bag, quick freezing and further freezing. The present invention has the advantages of keeping its original color, no change in its surface color and gloss, as well as bactericidal effect superior to heat sterilization. Total count of bacteria colonies per 1 g sample is less than 1000, and total count of Coliform bacteria per 100 g sample is less than 3.

The invention discloses an environmentally friendly and easily decomposable vegetable oil-based lubricating oil and a production process thereof, belonging to the field of lubricating oil. The lubricating oil of the present invention adopts vegetable oil as the base oil, and the mass ratio of the base oil and the additive is 7:3, wherein the base oil includes high oleic sunflower oil and castor oil, and the quality of the high oleic sunflower oil and castor oil is The ratio is 6:4. Among them, high oleic sunflower oil, with an oleic acid content of up to 90%, has extremely high antioxidant properties, while castor oil has an ideal viscosity. The two are used in a ratio. As an ideal vegetable oil, no special processing is required. Advantageous characteristics of conventional mineral oils as base oils. In addition, through the auxiliary modification of additives, no special processing is required, and it can be put into use after simple proportioning and high-temperature smelting. The production cost is low and it is easy to popularize.

The invention relates to a method for producing regenerative heavy denier profiled polyester staple fibres. The method comprises the following main procedures: selecting high-quality regenerative polyester bottle chips and spinning the bottle chips to form fibres with profiled sections through drying, melting spinning, cooling, drawing and setting. The method has the following main characteristics: A) after being dried, the moisture contents of the regenerative polyester bottle chips are below 80PPM; B) the melting temperature is controlled between 270 DEG C and 285 DEG C and the spin beam temperature is controlled between 275 DEG C and 278 DEG C; and C) a mist and recirculating air dual-purpose cooling device is adopted for cooling, the mist spray speed is 3.8-4.0m / s and the water temperature is not more than 30 DEG C. The method has the following positive effects: by adopting the cooling method and device combining mist spray cooling and recirculating air cooling for the fibres which are extruded, melted and spouted, the good setting property of the profiled sections of the fibres is ensured and the problem that the sections of the fibres tend to be round due to surface tension existing when the polymer melt is extruded from the spinneret orifice is solved, so that the fibres have multidimensional reflecting effects as the diamond shaped mirrors.

The invention relates to a tearing device, in particular to a wearable medical adhesive tape tearing device. Technical problem: To provide a wearable medical tape tearing device that is easy to operate and not easy to reduce the adhesiveness of the tape. The technical solution is: a wearable medical tape tearing device, including a cylindrical box, a cover, a first bearing seat, a rotating shaft, a second bearing seat, a rotating rod, etc.; the top of the cylindrical box is provided with a cover, and the cover is connected with The cylindrical box is matched, and a first bearing seat is embedded in the middle of the bottom of the cylindrical box. The first bearing seat is connected with a rotating shaft, and a cavity is opened on the rotating shaft. Through the function of the first bearing seat, the present invention can allow the rotating shaft to rotate with the tape, so that the medical staff can pull out the tape better, and the tape can be torn off by the toothed blade, which is easy to operate and does not reduce the stickiness of the tape; The adhesive tape can be pressed by the pressing mechanism to prevent the adhesive tape from rotating when the toothed blade is tearing off the adhesive tape, so that the toothed blade can better tear off the adhesive tape.

The invention discloses a varnish for releasing negative ions and a preparation method thereof. The varnish for releasing negative ions is mainly composed of negative ion powder mixed with LED varnish, and the negative ion powder is 35-45 parts , 95-105 parts of LED varnish; the preparation method includes the following steps: S1: prepare anion powder and LED varnish; S2: heat the LED varnish prepared in step S1 in a water bath; S3: heat the LED varnish produced in step S1; The prepared negative ion powder is added to the LED varnish in S2 and stirred, and the negative ion powder is fully mixed with the LED varnish to obtain a varnish with negative ion powder. The varnish coated on the surface of the object can radiate air The air is ionized to release negative oxygen ions, remove the formaldehyde in the room, purify the indoor air, reduce the content of formaldehyde in the air, and at the same time provide negative oxygen ions for the room to create a healthy environment for people.
