Acid and alkali chemical protective clothing testing instrument use precautions Zhongbang

Acid and alkali chemical protective clothing is used in special industries. Its anti-acid and alkali properties directly affect the safety of users. Therefore, the fabrics of acid-base chemical protective clothing must undergo rigorous testing before being used in the factory. This convenient issue, the Chinese National Standardization Committee released the latest GB24540-2009 "protective clothing, acid and alkali chemical protective clothing" standard, which is divided into three testing equipment according to the test items inside, ZF-631-1 acid and alkali resistance The tester, ZF-631-2 static acid pressure tester and ZF-631-3 acid permeation time tester also need to pay attention to the personal safety of operators when using these three devices. Here are some of the devices Operational notes:

Rejection of acid and alkali performance tester Note 1, when the instrument is not used for a long time, must carry out the residual solution emptying operation! After completing this step, it is best to use a cleaning agent to repeat the test and emptying steps to thoroughly clean the piping.

2. Do not open the door of the electrical box while the instrument is in operation.

3, acid and alkali have a certain degree of corrosion, test personnel should wear anti-acid / alkali gloves to avoid personal injury.

4, the instrument power supply should have a good grounding!

5. During the use of the instrument, there will be leakage of acid-alkali liquid inside the upper tank, which has been used for pouring out. It is necessary to open the door to handle the leaked liquid and clear the pipeline.

Static acid pressure tester Note 1, acid and alkali have a certain degree of corrosion, test personnel should wear anti-acid / alkali gloves, to avoid personal injury.

2. When the reagents are added, it is necessary to introduce the diversion tube slowly, and it is forbidden to pour it directly.

3. During the test, the glass door in the sample position must be closed.

4. If something unexpected happens during the test, please turn off the power of the instrument in time and clear it before using it again.

5. When the instrument is not used for a long time or when the reagent type is changed, the residual solution emptying operation must be performed! After completing this step, it is best to use a cleaning agent to repeat the test, emptying steps, and thoroughly clean the pipeline.

6, the instrument power supply should have a reliable grounding!

Note for Acid Permeation Time Tester 1. When taking reagent (test acid), be sure to wear anti-acid gloves and suck it with a pipette;

2. During the test, dropper drops (test acid) should be used;

3. After the test is completed, clean the test bench and the instrument surface in time to prevent corrosion.

4, the instrument must have a reliable grounding line.

Optical Prisms

A prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application,prism: In optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light.

Dispersive prism can be used to break light up into it's constituent spectral colors(the color of the rainbow).Furthermore, prisms can be used to reflect light or to split light into components with different polarizations.

Optical Prism include Right angle prism.Equilateral dispersing prism.Dove Prism.Corner Cube Reflectors.Beamsplitter, Powell prism, dove prism, wedge prism, penta prism etc.
