The designed drawing head is a cylindrical cylinder, a water filling hole and a clamping groove are formed in the upper part of the drawing head, a lower space of the cylinder is an ice forming cavity, the inner wall of the ice forming cavity is a positive sharp wave type coarsening surface, an opening at the lower end of the ice forming cavity is a direct-connection port or an inward-inclining shrinking port, and the contact area between the bottom of the ice forming cavity of the drawing head and a tested sample is not more than 1% of the bonding area between a molded ice pillar and the tested sample. According to the drawing head disclosed by the utility model, the design is novel, the inner wall of the ice forming cavity is the positive sharp wave type coarsening surface, so that the friction resistance and the holding force between the surface of the molded ice pillar in the ice forming cavity and the inner wall of the cavity of the drawing head in the ice forming cavity can be increased greatly, and in the drawing process, the condition that the tensile strength of the ice pillar is far higher than the bonding strength of the ice pillar and a base material is ensured, the accuracy of test data is ensured, and in order to evaluate the relative bonding strength of ice coating layers and the differences of the bonding strength of different base materials, a rapid and reliable elevation device is provided.
Description
Technical field
A kind of drawing head that is used to test the ice bonding strength of the utility model belongs to planar substrate surfaces ice bonding strength proving installation.
Background technology
Under physical environment, the icing phenomenon may take place in body structure surfaces such as power transmission and transformation line, signal iron tower, wind electricity blade, radar antenna and aircraft; Under extreme environment and condition, icing may cause serious accident.Therefore need conduct a research and estimate the formation of icing and solution thereof, wherein important content be a test ice and the bonding strength of matrix.The bonding strength test of icing in the laboratory is a kind of evaluation method efficiently; But up to the present also there be not a kind of special being used to test the drawing head of ice bonding strength; And when using conventional bonding strength test to ice the bonding strength test, need the drawing head of proving installation steadily be placed on moisture substrate surface with the drawing head, together place in the refrigerating chamber freezing icing; Reach the freezing temperature of regulation and after the time, take out and carry out pull-out test.Because the viscosity of water is little, mobile strong, defectives such as in the process of placing the drawing head, bonding plane occurs easily that water is lepthymenia, blocked up, inclination, bubble or breakage; The volumetric expansion of water in freezing process is prone to cause bonding bad; The little sample that causes of thermal capacity because of the metal drawing head perhaps occurs and be fetched into problems such as the rate of rise in temperature of icing the test process is too fast from refrigerating chamber, make test data dispersed big, test findings is inaccurate.Therefore the parameter of ice sheet during standard ice bonding strength is tested, the accuracy of raising test data becomes one of focus of paying close attention in the industry.
The utility model content
The purpose of the utility model provides a kind of drawing head that is used to test the ice bonding strength; With the normative testing condition; Accurately record the ice and the bonding strength of base material, relative bonding strength and difference thereof for the icing layer of estimating the different matrix material provide quick evaluating apparatus reliably.
The purpose of the utility model realizes through following technical scheme:
The utility model is used to test the drawing head of ice bonding strength, is a column type cylindrical shell, and water injection hole is arranged at top; Holding tank; The cylindrical shell lower space is to become to ice die cavity, and becoming ice die cavity inwall is sharp wave mode coarse surface, and becoming ice die cavity lower ending opening is straightthrough port or introversion reducing.
The utility model drawing innovative design; It becomes ice die cavity inwall is the coarse surface with sharp wave mode; Increased greatly become to become in the ice die cavity icicle surface area and with the frictional resistance and the hold of drawing head dummy cavity wall; Guarantee in drawing process icicle self tensile strength (cohesive strength) far above the bonding strength of icicle and base material, thereby guarantee the accuracy of test data; Simultaneously the contact area of drawing head and base material and ice are compared very for a short time with the bond area of base material, and its influence to the bonding strength test data is controlled in the test error scope, have plurality of advantages such as easy to use, data reappearance is good, accuracy height.
When using the test of this ice bonding strength to test with the drawing head; The drawing head is placed on substrate surface to be measured, and the peripheral outer that the drawing head contacts with base material is sealed to prevent oozing out of water, an amount of water of the inner can of drawing head with hydrophobic material; Together be placed in the refrigerating chamber; Reach the freezing temperature of regulation and after the time, take out and carry out pull-out test, the accuracy of test data is high; Relative bonding strength and difference thereof for the icing layer of estimating the different matrix material provide quick evaluating apparatus reliably.
