A socket having an overheating destructive limiting element includes a housing, a live wire conductive plate, a neutral wire conductive plate, at least one live wire terminal, at least one neutral wire terminal, and at least one limiting element. The live wire terminal includes a live wire contact portion in contact with the live wire conductive plate. The neutral wire terminal includes a neutral wire contact portion in contact with the neutral wire conductive plate. The limiting element is an insulating body, and is placed at contact parts of the live wire conductive plate and the live wire contact portion, and / or at contact parts of the neutral wire conductive plate and the neutral wire contact portion. When an operating temperature becomes excessively high, the limiting element becomes deformed and destructed to form a turn-off position.

The invention relates to a fucoidan extract method, in particular to a method for extracting fucoidan for brown seaweed, comprising the following steps: 1. desalting: adopting fresh brown seaweed or unfreezed frozen brown seaweed to soak in pure water to remove salt; 2. enzymolysis: adding enzyme in the desalted brown seaweed to perform enzymolysis at 40-60 DEG C for 1-3h; 3. abstraction: adding calcium chloride in enzymatic hydrolyzate obtained by enzymolysis, and heating the solution to 90-100 DEG C for 1-4h to obtain the fucoidan extract. The invention is characterized of simple operation, high application security, high extraction efficiency, high extraction purity and the like and the extraction process is applicable to factory mass production.

The invention relates to a method for realizing APK unified signature by using three-level certificate authentication, which adopts a three-level certificate chain including a CA certificate, a user equipment certificate, a user root certificate and a user working certificate to carry out CA authentication, the CA certificate is integrated into firmware, and the user equipment certificate is preset into equipment when the equipment leaves a factory. The POS terminal integrated with the scheme can download different user terminal certificates to support diversified application signature verification requirements of users, such as SM3WithSM2, SHA3-256WITHRSA and the like, manufacturers do not need to customize versions for clients due to the signature verification scheme, version managementis facilitated, and development cost is reduced.

The invention discloses a wear-resistant electrostatic-resistant flame-resistant ultrahigh molecular weight polyethylene composite material. The composite material is prepared by performing mixing on ultrahigh molecular weight polyethylene with a viscosity-average molecular weight of 3-3.5 million and an electronic-resistant material by an open mill to form a mixture, then adding a filling material, a novel bromine-based compounded fire retardant, and proper amount of flow modifier, coupling agent, compatibilizer and anti-oxidant, and processing by a double screw extruder, wherein ultrahigh molecular weight polyethylene accounts for 40-60 parts, the filling material accounts for 15-20 parts, the novel bromine-based compounded fire retardant accounts for 20-25 parts, the electronic-resistant material accounts for 5-15 parts, the flow modifier accounts for 5-8 parts, the coupling agent accounts for 0.2-0.5 part, the anti-oxidant accounts for 0.2-0.5 part, and the compatibilizer accounts for 0.2-0.5 part. The above raw materials are weighed according to the above ratio and are mixed by the open mill for forming the mixture, and the mixture and the raw materials weighed according to the above ratio are extruded by the double screw extruder for preparation of the composite material. The composite material is widely applicable to fields of mines, ships, coal and the like. The preparation technology provided by the invention is easy to control, high in production efficiency and stable in quality.

The invention discloses a building curtain wall safety nondestructive testing imaging method based on microwave imaging, and the method comprises the following steps: respectively imaging defective curtain walls and newly built curtain walls under different working conditions, extracting imaging features of various defects, and taking the imaging features as identification elements of the defects to establish a feature library; setting detection equipment and carrying equipment, and confirming an initial acquisition position; carrying out comprehensive scanning detection on a to-be-detected curtain wall to realize microwave imaging; identifying a microwave imaging result, comparing the microwave imaging result with data in the feature library, marking working conditions with the same features, determining defect types, and reminding a person in charge to further observe and confirm; and determining a defect position and combining a defect type, and recording the defect position, the defect type and a non-conformance condition according to the conformance condition of the drawing, the standard and the feature library. According to the method, comprehensive scanning detection is completed on the premise that the original structure of the curtain wall is not damaged, accidental factors caused by sampling inspection are avoided, detection is more accurate, and the detection effect is good.
