The electronic remote control lock head can be unlocked by an emergency key in emergency circumstances, and the trouble and loss of overall dismounting of the electronic lock are avoided; the concealment of an emergency key hole is good, and the safety is high.

The invention provides an additive composition used for a piglet feed. The additive composition comprises tannic acid, sanguinarine and an epimedium herb extract, wherein the mass ratio of the tannic acid, the sanguinarine and the epimedium herb extract is (750-1300):50:(300-800). The invention also provides a compound premix containing the additive composition and an antibiotic-free piglet feed containing the additive composition. The additive composition, and the compound premix prepared from the additive composition, and the antibiotic-free piglet feed prepared from the additive composition have a plurality of functions of improving intestinal microflora balance of piglets, raising immunity, and resisting diarrhea. No antibiotic is added, so that the feed has high safety and accords with an ideal amino acid mode. Coordination on the aspects of electrolyte balance and mineral balance is carried out, so that the feed can comprehensively meet nutrient and health demands of piglets, and price performance ratio is taken into account at the same time so as to greatly raise benefits of pig farms.

The invention discloses a modified dioscorea opposita thunb starch prepolymer and a degradable polyurethane foam material prepared from the prepolymer. A preparation method of the modified dioscorea opposita thunb prepolymer comprises the following steps: (1) putting polyisocyanate and polycaprolactone, the molar ratio of which is 2: 1, into a container, reacting at the temperature of 80+/-2 DEG C for 3-5 hours, and then degrassing under a negative pressure till bubbles do not exist, thus obtaining a polycaprolactone prepolymer; and (2) dissolving modified dioscorea opposita thunb starch and the polycaprolactone prepolymer in a dimethylsulfoxide solution at the temperature of 60-70 DEG C, then adding a catalyst NaCNBH3, reacting for 2-3 days under a stirring condition, after ending reaction, cooling obtained mixed liquid to a room temperature, then dropwise adding the mixed liquid to methyl alcohol under a stirring condition so as to form precipitates, filtering to obtain the precipitates, and drying under reduced pressure so as to obtain the modified dioscorea opposita thunb starch prepolymer.

The invention relates to a cultivation domestication technology of funguses, and belongs to the field of microorganism and microorganism application. A wild trametes orientalis Imaz domestication cultivation technology comprises the steps that wild trametes orientalis Imaz is collected from the wild, tissue and matrix separation, mycelium purification cultivation and domestication are conducted, and wood flour of banyans, bran, corn flour, saccharose, Ca(OH)2, MgSO4 and KH2PO4 are processed and mixed to form culture media according to the weight ratio of 100:20-25:6-8:6-8:0.6-0.8:1-2:0.2-0.4:0.3-0.6; in the hypha growing step, cultivation temperature, water content of the culture media, space humidity and pH values are controlled; illumination intensity and CO2 concentration in the environment are used for domestication and cultivation of the wild trametes orientalis Imaz. By means of the cultivation domestication technology, the cultivated trametes orientalis Imaz has good officinal and health-care value, can replace wild resources better, and has high development and popularization value.

The invention relates to a control circuit of powder feeder for hypersonic flame spraying, comprising a first potentiometer, a first speed control panel, a first voltmeter, a first power tube, a second potentiometer, a second voltmeter, a second motor, a second speed control panel, a second power tube, a first switch, a second switch, a first electromagnetic valve, a second electromagnetic valve, a transformer, a first motor and a power strip. The first motor and the second motor allows two feeding branches to be controlled; compared with the traditional single-channel feeding way, the feeding way using the two motors has the advantages that feeding efficiency is improved, the single device is used for two hypersonic flame spraying devices, the production cost is lowered, a replacement function is good, if one feeding branch has a control fault, the other feeding branch can be controlled instead, and smooth spraying is guaranteed.

The invention relates to a reusable waterborne polyurethane shielding material and a preparation method thereof. The preparation method of the material comprises the steps that: 1, any one or a combination of two or more of polypropylene oxide glycol, polypropylene oxide triol, polytetrahydrofuran ether diol and 3001 polyester polyol, and a plasticizer, are weighed and placed in a reactor filled with nitrogen, stirring the materials at the temperature of 75-95 DEG C and reacting for 15-30 minutes; (2) adding toluene diisocynate, an emulsifier and a curing agent into the reactor, adjusting thewater bath temperature to 80-95 DEG C, and stirring for 30-50 minutes; (3) adding polyethylene glycol monomethyl ether, continuously reacting for 1-2h, dropwise adding a cross-linking agent and a chain extender, adding deionized water to adjust the solid content to 40-60%, continuously reacting for 1-2h, and performing cooling; and (4) adding talcum powder into the raw materials obtained in the step S3, and performing uniform stirring to obtain the waterborne polyurethane shielding material. The material is waterborne polyurethane, can realize good bonding and shielding effects, and has the advantages of high viscosity, reusability, simplicity in operation, no pollution in after-treatment and the like.
