With the development of the economy, more and more electronic and military products require the use of constant temperature and humidity boxes for high temperature, low temperature, constant damp heat, alternating heat and humidity environment simulation tests, some of which have the possibility of explosion in the test, such as Lithium batteries, etc., therefore require a constant temperature and humidity box with an explosion-proof function to accommodate a wider range of test samples. In order to achieve the explosion-proof function, it is necessary to make corresponding changes in terms of control, electrical and structural aspects. Explosion-proof must first consider the concentration of flammable gas in the tank during the simulation test. When an abnormality is found, the constant temperature and humidity chamber should take measures to reduce the concentration of flammable gas to avoid accidents such as burning and explosion; once an explosion occurs The strength structure and protective measures of the test box are particularly important. When properly protected, it can reduce economic property losses and avoid casualties.
An eye with brown eye liner under the bottom lashes.
Eye liner is commonly used in a daily make-up routine to define the eye or create the look of a wider or smaller eye. Eye liner can be used as a tool to create various looks as well as highlighting different features of the eyes. Eye liner can be placed in various parts of the eye to create different looks with a winged eye liner or tight lined at the waterline. Eye liner can be drawn above upper lashes or below lower lashes or both, even on the water lines of your eyes. Its primary purpose is to make the lashes look lush, but it also draws attention to the eye and can enhance or even change the eye's shape. Eye liner is available in a wide range of hues, from the common black, brown and grey to more adventurous shades such as bright primary colors, pastels, frosty silvers and golds, white and even glitter-flecked colors.
