Problems solved by technology

However, the porosity is not as high as possible. Too many pores will increase the loss of the substrate and the finished board, which does not meet the actual needs.
[0004] In addition, after the production of the insulation board is completed, the flexural strength of the insulation board needs to be tested. Usually, the cut part of the whole insulation board is tested. Since the pores formed on the substrate are not uniform, each part of the whole insulation board There may be differences in the flexural strength of the insulation board, so only testing the part of the insulation board may affect the evaluation of the flexural strength of the insulation board; and after the flexural strength test is performed, the entire insulation board will be discarded, resulting in waste of materials , especially the waste of polystyrene foam particles

Embodiment 1

[0030] The method for detecting the performance of the insulation board comprises the following steps:

[0031] Step 1: Prepare as figure 1 The detection equipment shown, the detection equipment includes a frame, an air compressor, a cutting and pressing mechanism and a supporting crushing mechanism. The cutting and pressing mechanism includes a cylinder, a stepping motor, a connecting plate 1, a cutting knife 2 and a pressing block 3, and the cylinder It is vertically fixed and installed on the frame by bolts, and the air cylinder can be selected as Yadeke SC air cylinder; the stepping motor is vertically installed and welded with the output shaft of the air cylinder, the connecting plate 1 is welded with the output shaft of the stepping motor, and the stepping motor The optional model is ZX7H-57BYG007-01.

[0032] Such as figure 2 As shown, the cutting knife 2 is arranged crosswise on the lower surface of the connecting plate 1, and the cutting knife 2 and the connecting ...

Embodiment 2

[0041] On the basis of Example 1, as image 3 Each side of the broken block 5 shown is welded with a number of broken nails, and the broken nails on each side of the broken block 5 are randomly distributed. In addition, among the four side walls of the support frame 4, three of the side walls are welded to the bottom of the support frame 4, and the other side wall is connected to the adjacent side wall by hinge rotation, that is, the side wall is rotated and opened to facilitate The particles in the support frame 4 are swept out.

Embodiment 3

[0043] The difference from the second embodiment is that the bottom of the bayonet 6 is higher than the upper surface of the broken block 5, and also includes a cylinder, the upper and lower ends of the cylinder are open, and the marking line I is marked at the height of the cylinder at 25cm and 15cm respectively. and engraved line II, after the substrate is placed on the support frame 4, make the lower end of the cylinder contact with the upper surface of the substrate, and seal it with silicone sealant, fix the cylinder by hand and pour 2kg of tap water inward, pour Time 2 ~ 3s, record the water level drop time, from the beginning of the marking line Ⅰ to the end of the marking line Ⅱ; after data analysis, the best water flow penetration time is 7-9s, at this time the porosity of the EPS substrate is the best, and the comprehensive performance is the best .

Abstract

The invention relates to the field of strength detection, in particular to a method for detecting performance of an insulation board. The method comprises the following steps of: 1, preparing detection equipment comprising an air compressor, a negative pressure suction filter, a slitting knife and a pressing block; 2, detecting a pore permeation condition of a substrate; 3, making the slitting knife to be in contact with the upper surface of a heat preservation plate; 4, enabling the slitting knife to rotate to scrape the upper surface of the heat preservation plate to be flat; 5, making a pressing block to be in contact with the cut heat preservation board, and pressing the heat preservation board until the heat preservation board is broken; and 6, crushing the broken heat insulation board. When the method is adopted, the porosity of the substrate can be detected, the breaking strength of the heat preservation board can be quickly and accurately detected, and the heat preservation board can be conveniently recycled.

Description

technical field [0001] The invention relates to the field of strength detection, in particular to a method for detecting the performance of a thermal insulation board. Background technique [0002] Modified polystyrene board is a kind of low-density EPS (polystyrene) substrate (hereinafter referred to as substrate) and inorganic gelling material, which is uniformly infiltrated, cured and dried. It has thermal insulation and fire protection level A2. A new type of thermal insulation material; that is, a number of pores are formed on the EPS substrate, and the inorganic gelling material is infiltrated into the pores and then cured and dried to form a thermal insulation board. [0003] Among them, the porosity of the substrate directly determines the fireproof grade of the finished fireproof insulation board. If there are more inorganic gelling materials infiltrated, the fireproof grade can reach A2 grade, and if the infiltrated inorganic slurry is less, the fireproof grade can...
