Embodiment 1

[0024] Such as Figure 1~4 Shown, a kind of multifunctional support experiment box of the present invention comprises box body, and box body is divided into upper box body 1, lower box body 2, and upper box body 1 comprises four side boards 3 and top board 4, top board 4 and four Any one of the side panels 3 is connected to the hinge 12, and the top panel 4 can rotate 360 ​​degrees around the hinge 12, and can also be fastened together with the side panels 3, and the adjacent side panels 3 are provided with buckles 13. They can be connected to each other to form a box structure. The opposite sides of the side plate 3 are respectively equipped with locks 5, and the opposite sides are respectively coated with an acid and alkali resistant coating 15 and a high temperature and refractory coating 16. A hinge 9 is installed between the lower box 2 and the upper box 1, and the hinge 9 includes a swivel seat 91 installed at the four corners of the lower box 2, and a hinge rod 92 is in...

Embodiment 2

[0029] Common acid-base solutions in high school chemistry experiments include sulfuric acid, hydrochloric acid, nitric acid, hypochlorous acid, acetic acid, sodium hydroxide, ammonia water and other reagents. When it is used, it can prevent acid and alkali reagents from corroding the desktop, causing blackening and cracking of the desktop. Acid-resistant and alkali-resistant coating is based on polyester paint, followed by spraying γ-Al 2 o 3 Composite coating, ɑ-Al 2 o 3 Formed by ceramic paint, it can be adapted to routine experiments in high school chemistry experiments.

[0030] The preparation steps of acid and alkali resistant coating are as follows:

[0031] 1) Under the action of vigorous magnetic stirring at 1000r / min, γ-Al 2 0 3 Mix the powder with 6% ammonia solution at a ratio of 1:3, then add nano-scale titanium dioxide powder, nano-scale silicon powder, γ-Al 2 0 3 The ratio of powder to nano-scale titanium dioxide powder and nano-scale silicon powder is ...

Abstract

The invention relates to the chemical experiment equipment technology field and particularly relates to a multifunctional support experiment case. The multifunctional support experiment case comprisesa cabinet body. The cabinet body is divided into an upper cabinet body and a lower cabinet body. The upper cabinet body comprises a top plate and four side plates. The top plate and the side plates are buckled together to form a cabinet structure. Lock catches are arranged on two opposite surfaces of the side plates. The two opposite surfaces of the side plates are coated with an acid-alkali resistance coating and a high-temperature-and-fire resistance coating. A hinge member is installed between the lower cabinet body and the upper cabinet body. Two cabinet doors which can be opened toward opposite directions are installed on the lower cabinet body. Object placement grooves are installed on the inner side walls of the cabinet doors. A hinging seat is installed on the outer side of the wall plate of the lower cabinet body. A support rod is hinged with the hinging seat. A hook is installed on the other end of the support rod. The hook cooperates with the lock catches. The multifunctional support experiment case can solve problems that current chemical experimental apparatus are diversified and are not easy to carry, can make people use a simple experiment operation platform under acondition that people can make experiments somewhere else other than on a lab operation table and people can choose table surfaces with different coatings to face upwards.

Description

technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a multifunctional support experiment box. Background technique [0002] Chemistry experiment is one of the compulsory courses for middle school students. The core of chemistry course is the chemical reaction of substances. At the same time, chemistry is also a natural science based on experiments. In the teaching process, many reactions or phenomena need to be verified through experiments to strengthen students' memory and understanding. Different experimental processes require different equipment and drugs. It is often necessary to complete multiple experiments in a short period of time, which requires a lot of medicines and equipment to be placed on the test bench. [0003] In some areas, the space resources are limited, the size of the space that meets the experimental requirements is limited, and the distribution is uneven. The medicines and equipment p...
