Full-automatic four-sample simultaneous-analysis water absorption capacity determination instrument for rock wool board and determination method thereof

Abstract

The invention discloses a full-automatic four-sample simultaneous-analysis water absorption capacity determination instrument for a rock wool board and a determination method thereof. The determination instrument comprises a mechanical working part and a control system, wherein the mechanical working part comprises a base and four stand columns which are vertically fixed on the base; four transverse beams are horizontally arranged at the top ends of the four stand columns and the bottom of each transverse beam is connected with an electronic balance; the bottom of each electronic balance is connected with a thickness adjustable sample fixing frame; each thickness adjustable sample fixing frame is internally provided with a rock wool test sample and a water groove is arranged below the four thickness adjustable sample fixing frames; an automatic hoisting platform is arranged between the water groove and the base; the control system comprises a central control module, and a movement control module and a data analysis module which are connected with the central control module respectively; the movement control module is connected with the automatic hoisting platform; the data analysis module and the central control module are connected with the four electronic balances. The full-automatic four-sample simultaneous-analysis water absorption capacity determination instrument is simple to operate, accurate in determination data and high in automation degree.

Description

technical field [0001] The invention belongs to the technical field of building material detection equipment, and in particular relates to a rock wool board water absorption measuring instrument and a measuring method thereof. Background technique [0002] In recent years, with the vigorous promotion of green buildings, energy-saving projects have played an increasingly important role in buildings. As an important part of energy-saving projects-the requirements for external wall insulation have also become higher and higher. Rock wool boards are used as a high-quality Building exterior wall insulation materials have the properties of heat preservation, heat insulation, fire prevention, sound insulation, no corrosion, no radioactivity, environmental protection, and energy saving, and have been widely used. [0003] Since the rock wool insulation board is a kind of fiber material, and it has been in the natural environment of wind, sun, and rain for a long time, once the rock ...

Problems solved by technology

[0003] Since the rock wool insulation board is a kind of fiber material, and it has been in the natural environment of wind, sun, and rain for a long time, once the rock wool board absorbs a certain amount of water, its thermal insulation performance will be greatly reduced. "Using Rock Wool Products" (GB / T25975—2015) has made strict regulations on the water absorption of rock wool insulation boards, and described the principle of the determination of the water absorption of rock wool boards in Appendix B, but due to The detection instruments are relatively simple, and the measurement methods are all manual operations, which makes the consistency of the measurement data poor

It is mainly reflected in the inaccuracy of the height of the soaking water surface, the temperature of the soaking water is not constant, and the difference between the soaking time and the draining time is large. Although the details of these operations do not affect the qualitative judgment of the material performance, the accuracy of the data will be affected by the quantitative judgment. Big discount
