Technical Field

The invention relates to the field of material phase analysis, in particular to a novel XRD asbestos sample detection bearing platform.

Background

Asbestos has good insulating and heat-insulating properties and is widely applied to industries such as chemical industry, electrical equipment, ship manufacturing, building industry and the like. However, as the harm of asbestos gradually appears, asbestos causes the occurrence of asbestos lung, pleural mesothelioma and even cancer, asbestos is banned gradually on a global scale, and meanwhile, the demand for asbestos detection on materials is increased.

At present, according to asbestos detection practice and referring to relevant standards at home and abroad, a means of combining an XRD instrument and a PLM instrument is mainly adopted as a technical method for detecting asbestos in industrial products. In the quantitative detection process of asbestos, a treated sample needs to be filtered on glass fiber filter paper, and a background plate is lined to acquire phase information through XRD.

The existing asbestos filter sheet is easy to slip off in the installation process, the situations of incomplete installation, low installation power and the like occur, even the loss of asbestos content is caused, and the accuracy of an experimental result is influenced.

Disclosure of Invention

In order to solve the problems of improper installation and low installation power caused by easy slipping in the installation process of the existing asbestos filter disc, the invention provides a novel XRD asbestos sample detection bearing table which can be matched with an existing XRD rotary sample table for use to realize dynamic rotary analysis of a detection sample, and the technical purpose of the invention is realized by the following technical scheme:

the utility model provides a novel XRD asbestos sample test plummer, its structure includes the objective table base, supports reed, background board, lid thing piece, supports the reed and installs in the objective table base, and the background board sets up in supporting the reed upper end, and lid thing piece ballast is in the background board upper end, the lock between lid thing piece and the objective table base.

During the use, place the asbestos filter disc between background board and lid thing piece, will cover thing piece and objective table lock, support the reed and support the background board from the lower extreme for the asbestos filter disc is stably fixed on the background board, uses this plummer cooperation X-ray diffractometer's rotatory sample platform, and then realizes the rotatory analysis of the developments of testing sample.

Further, the support reed is the dish-shaped reed, and the upper end of dish-shaped reed forms the objective table, sets up the background board on the objective table, and dish-shaped reed atress is more even, and is more steady to the support of background board.

Furthermore, a carrying groove is formed in the carrying platform base, the supporting spring plate is installed in the carrying groove, the upper end of the carrying groove is opened, and the cover sheet is buckled at the opening of the carrying groove.

Furthermore, the opening of the object carrying groove is provided with a check ring, the check ring is evenly provided with a plurality of positioning clamping grooves, the edge of the object covering sheet is provided with a plurality of positioning clamping plates corresponding to the positioning clamping grooves, and the positioning clamping plates are clamped into the lower end of the check ring from the inner rotating part of the positioning clamping grooves.

Furthermore, the middle part of the object covering sheet is provided with an excitation hole for collecting phase information by irradiating X-rays on the background plate and the asbestos filter sheet.

Furthermore, the thickness of the positioning clamping plate is smaller than that of the cover object sheet, and the lower end face of the positioning clamping plate is flush with the lower end face of the cover object sheet.

Furthermore, a rotating groove is arranged on the outer side of the base of the object stage.

Compared with the prior art, the invention has the beneficial effects that the asbestos filter sheet is clamped from the upper end and the lower end through the supporting reed and the cover sheet respectively, so that the asbestos filter cotton is stably fixed on the background plate, the problem that the asbestos filter sheet slides off in the installation and use process is solved, the influence of the asbestos content loss on the test result is further reduced, and the accuracy of the test result is improved.
