Problems solved by technology

[0005] At present, the diatom mud market is mixed with good and bad, and the competition is very fierce, mainly manifested as unprofessional, unstable, and irregular
Some merchants even use other materials to counterfeit diatom mud, which has brought potential hidden dangers to the diatom mud industry
Although the national industry standard "Diatom Mud Decorative Wall Materials" has a method for the determination of diatom components, the operation of X-ray diffractometers, electron microscopes and other equipment used in this method is relatively complicated.

Abstract

The invention relates to the technical field of detection of decorative building materials, and more particularly to a method for observing diatom ooze by a polarizing microscope. The method comprisesthe following steps: 1) weighing 28 g to 32 g of commercially available diatom ooze and placing the diatom ooze into a mortar, and adding 4 ml to 6 ml of alcohol to mix and grind for 4 to 6 minutes;2) taking 14 g to 16 g of evenly ground diatom ooze in step 1) into a beaker, adding 140 ml to 160 ml of alcohol, and placing the beaker on a magnetic stirrer for stirring for 8 to 12 minutes; and 3)sucking, with a straw, 4 to 6 drops of the mixed liquid obtained in step 2) onto a slide, then covering the slide with a cover glass, and then observing the diatom ooze by the polarizing microscope. The method effectively improves the diatom ooze observing efficiency after pre-mixing treatment; and the method is simple in process, has quickness in detection and has high economic benefit.

Description

technical field [0001] The invention relates to the technical field of detection of building decoration and decoration materials, in particular to a method and application for observing diatom mud with a polarizing microscope. Background technique [0002] Diatom mud is a new functional interior wall decoration environmental protection material emerging in my country in recent years. It has many functions such as adjusting humidity, purifying air, fire retardant, sound absorption and noise reduction, thermal insulation, eye protection, wall self-cleaning, etc. . Diatom mud not only has multiple functions, but also can be made into textures of various colors, with rich shapes and complete styles. Therefore, diatom mud has developed rapidly after being introduced to China in just a few years, and has been favored and recognized by customers. [0003] Diatomaceous earth is derived from diatom minerals formed by marine algae plants over hundreds of millions of years. Its main co...
