Recently, eight scientific and technological achievements declared by China Construction Western Construction Hunan Co., Ltd. have been granted national patents.
(1) a concrete underwater anti-dispersing agent and its preparation method and application
a scientific and technological achievement of Hunan Company, a concrete underwater anti-dispersing agent and its preparation method and application, was authorized by the State Intellectual Property Office. This achievement is based on the summary and refinement of the technical difficulties and innovations of a wharf bed repair project in Hainan undertaken by the company. The developed compound underwater dispersant is suitable for underwater repair projects with high requirements for construction timeliness, which can save the construction period and has good economic benefits.
(2) An architectural coating and its preparation method and application
a scientific and technological achievement of Hunan Company "An architectural coating and its preparation method and application" was authorized by the State Intellectual Property Office. The architectural coatings prepared by this achievement have the ability to adsorb and solidify carbon dioxide efficiently in the short term (within one year) and in the long term (within 50 years), and have the effects of anti-falling and anti-cracking.
(3) a kind of aggregate and its preparation method and application
a scientific and technological achievement of Hunan Company "a kind of aggregate and its preparation method and application" was authorized by the State Intellectual Property Office. The aggregate prepared by this achievement is used to prepare lightweight high-strength concrete, which has good performance advantages. When the concrete is prepared, the rehydration of the aggregate and the concrete paste form a good combination, which greatly improves the strength of the concrete.
(4) Test Method and Device
for Rheological Properties of a Cementitious Material a scientific and technological achievement of Hunan Company, Test Method and Device for Rheological Properties of a Cementitious Material, was granted an invention patent by the State Intellectual Property Office. The test method of this achievement is simple and time-consuming, and it can be used in laboratory, production ready-mix plant and construction site, and it has strong environmental adaptability and can be widely promoted.
(5) Device
for identification and removal of magnetic substances in aggregates a scientific and technological achievement of Hunan Company, "Device for identification and removal of magnetic substances in aggregates", was granted a utility model patent by the State Intellectual Property Office. By utilize that device, the aggregate can be fully identified, the magnetic substance in the aggregate can be effectively removed, and the risk that the quality of the concrete is influenced due to the fact that the magnetic substances exceed the standard is reduce.
(6) Concrete Sampling Device
a scientific and technological achievement of Hunan Company, Concrete Sampling Device, was granted a utility model patent by the State Intellectual Property Office. By using the concrete sampling device of the achievement, the uniformity of each component of the concrete can be improved, and the representativeness of the formed test block can be increased.
(7) Auxiliary Device
for Concrete Test Block Forming a scientific and technological achievement of Hunan Company, Auxiliary Device for Concrete Test Block Forming, was granted a utility model patent by the State Intellectual Property Office. The auxiliary device for forming the test block by using the result can accurately pour the concrete mixture into the test mold and reduce the risk that the concrete mixture is sprinkled on the ground.
(8) Concrete Test Block Demoulding Auxiliary Device
a scientific and technological achievement of Hunan Company, Concrete Test Block Demoulding Auxiliary Device, was granted a utility model patent by the State Intellectual Property Office. By utilizing the test block demoulding auxiliary device of the result, the whole concrete test block demoulding process is simple to operate, the test block is not required to be continuously lifted manually, and the test block is not required to be strongly shaken manually, so that the test block demoulding auxiliary device is more labor-saving, the working intensity is reduced, and the working efficiency is improved.
