The material prepared by the invention has excellent spray-free metal effect, good dust absorption and antibacterial properties, can effectively alleviate the flow mark problem of traditional spray-free metal effect materials, and is suitable for easy-to-breed bacteria and high dust adsorption It has a wide range of uses in the fields of automobiles, home appliances, and household goods.

The invention discloses a production process of a back piece of a backpack, relates to a backpack and aims to solve the problem of lack of breathability. The technical scheme of the production processof the back piece of the backpack is characterized by comprising steps as follows: S1, Dupont sorona fiber is carded in a thin net state through a roller carder and sent into a net paving machine onstandby, oyster fiber mixed hot-melt short fiber is carded in a thin net state by a roller carder, sent into the net paving machine and paved above sorona fiber, and a fiber net with 10-40 g / m<2> is prepared from the paved net and finally coiled to form a fiber net; S4, an inner-core blank is sent into a hot cutting press and is cut into a required appearance by a hot cutting die of the hot cutting press, and a filling inner core is prepared; and S5, the filling inner core is wrapped with fabric, and the back piece of the backpack can be made. By means of the production process of the back piece of the backpack, the breathability of the back piece of the backpack is effectively improved, so that the sweating capability is improved, and the hidden danger of breeding of bacteria is further reduced.

The invention discloses a breeding method of japonica photoperiod / thermo-sensitive genic male sterile lines. The method sequentially comprises the following steps of: single strain selection process, sterility identification process through linear light at a low temperature, fertility identification process through short light at a high temperature, core seed production process and breeder's stock and stock production process. In the sterility identification process through linear light at the low temperature, the daily sunlight time is more than 14.5 hours; the daily average temperature is 24 DEG C; and the day and night temperature amplitude is 20 to 28 DEG C. In the fertility identification process through short light at the high temperature, the daily sunlight time is less than 13 hours; the daily average temperature is 28 DEG C; and the day and night temperature amplitude is 25 to 30 DEG C. The core seed production process comprises a core rice stump preservative method in HannanProvince or a greenhouse core rice stump preservative method in middle and lower reaches of the Yangtze River, wherein the height of stump cutting in the breeding method is 20cm. The breeding method eliminates genetic drift phenomena in a japonica photoperiod / thermo-sensitive genic male sterile line breeding process and solves the problems of low yield, high risk and difficulty in operation in the japonica photoperiod / thermo-sensitive genic male sterile line breeding process.

The invention relates to artificial synthetic feed, in particular to artificial synthetic feed of chive maggot. The feed consists of mushroom powder taken as a main composition and yeast powder as an auxiliary material. The feed with the mixture ratio is used to feed the chive maggot; the survival rate, the pupation rate, the eclosion rate and the egg laying amount of a single female are quite close to the chive maggot fed by natural feed; and the average pupae weight of male and female is higher than the chive maggot fed by natural feed, thereby favorable condition for normal supply for the tested chive maggot.

The invention belongs to the technical field of metal processing. More specifically, the invention relates to a fully synthetic environment-friendly cutting fluid for aluminum alloy processing and a preparation method thereof. A fully synthetic environment-friendly cutting fluid for aluminum alloy processing, comprising the following components in parts by weight: 5-25 parts of ammonium carboxylate compound antirust agent, 5-30 parts of sulfonated castor oil, 2-2 parts of water-soluble lubricant 15 parts, 1-6 parts of monobasic acid, 0.5-2 parts of anti-mold and fungicide, 0.02-1 part of defoamer, 20-55 parts of water. The invention provides a kind of fully synthetic environment-friendly cutting fluid for aluminum alloy processing, which is compounded with sulfonated castor oil and water-soluble lubricant to provide high lubricating performance. As an oil-free cutting fluid product, it can replace low oil content under the same conditions In addition, the invention protects the aluminum alloy from discoloration through the compounding of ricinoleic acid, organic acid and special alcohol amine, and solves the high lubrication requirements in the process of aluminum alloy processing.

The invention relates to a heat exchanger, in particular a flat tube evaporator (1) for a vehicle air-conditioning unit, having at least one collecting tank (2) made of plate material, which is divided longitudinally into at least two chambers , while the tubes, especially the ends of the flat tubes, are inserted into the bottom of the collecting tank. Said collecting tank (2) has a tunnel-shaped collecting tank part (5), a substantially flat collecting tank part (4) forming the bottom of the collecting tank, and caps ( 6). At least one cover (6) is flat in the region of its outer edge and is positively positioned in the collecting tank.

The invention relates to the technical field of washing devices, and discloses a detergent release device which comprises an outer box, an inner box and liquid pumps. The inner box can be pushed intoouter box or can be pulled out of the outer box; the liquid pumps are used for pumping liquid in the inner box into the outer box, and shells of the liquid pumps and the inner box are of integral structures. The invention further discloses a washing machine. The washing machine comprises the detergent release device. The detergent release device and the washing machine have the advantages that theshells of the liquid pumps and the inner box are integrated with one another, accordingly, required assembling time can be saved, components can be reduced, and the material cost can be lowered; clean washing machine use procedures can be implemented, and accordingly mildew breeding risks can be reduced; the release precision can be improved, and accordingly washing procedures are safe and reliable.
