Abstract

The invention discloses a production auxiliary device for testing the strength of a heat insulation plate and a testing method. The production auxiliary device comprises a conveying mechanism, a pressure sensor and a controller, the conveying mechanism is used for conveying sample heat insulation plates; the pressure sensor is used for collecting a pressure signal of the sample heat insulation plate in real time and transmitting the pressure signal to the controller; the controller is used for receiving pressure signals collected by the pressure sensor and electrically connected with a start-stop control unit of the conveying mechanism, and when the pressure signals received by the controller change, an instruction is sent out to close the conveying mechanism. According to the production auxiliary device, the fracture length of the sample heat insulation plate can be obtained, the self-weight-resistant strength of the sample can be obtained through calculation based on the obtained fracture length, and the self-weight-resistant strength of the sample can be obtained through calculation based on the obtained fracture length. And the maximum allowable length of the heat insulation plate in actual production is determined by combining the position difference of the production auxiliary device and the heat insulation plate generating the maximum bending moment in actual production, and then the relationship among the density, the maximum allowable length and the maximum strength is obtained.

Description

technical field [0001] The invention relates to the technical field of heat insulation board production, in particular to a production auxiliary device and a test method for testing the strength of the heat insulation board. Background technique [0002] The nano-insulation board is made of low thermal conductivity nano-powder as the main body, adding reinforcing fiber, infrared sunscreen agent and mixed dry powder molding. [0003] In mass production in the workshop, the strength of the prepared sheet needs to be greater than the strength required to overcome its own weight, and the sheet strength is low, which will cause problems such as cracking and breaking during mold removal and handling. The higher the molding density, the greater the strength, but the thermal insulation performance will be affected by it, so it is necessary to select the appropriate density molding. [0004] Therefore, if the relationship between the density, size and strength of the nano-insulation...
