Traditionally, people call the corrosion test salt water test machine, salt water sprayer, corrosion aging or salt spray test chamber.
Typical salt spray test chamber> Corrosion test method: put the sample into a stable, saturated relative humidity (RH) environment, and for a certain period of time, such as 999H, use 5% NaCI solution as the condensed salt spray , Its temperature is 35 ~ 40s ℃;
Another method is called 100% relative humidity method. It is made with water that does not contain salt or any other chemical substances, and is often regarded as a humidity test method.
In the early days, the purpose of the salt spray test chamber was to verify the longevity of corrosion, by arranging various degrees of corrosion, or simply classifying the test as a pass or fail test. However, in reality, no one really puts the product in the environmental conditions of 20% brine, 35 ~ 40s ℃, 100% RH. Although there are still many laboratories still adopting this method, its problem is that There is no way to judge the relevance of product service life or end use.
Our general description of the spray system of the salt spray test chamber are: tower spray device plus no crystallizing nozzle. The following description will be refined to give you a more in-depth and detailed understanding of the spray system of the salt spray test chamber:
Salt spray test chamber spray device: spray using tower sprayer (tower height adjustable), guided salt spray, fine mist particles, natural settling; nozzle without salt crystallization, adjustable settling spray gas treatment: spray gas for two-stage stabilization Pressure regulation, pre-heat oil pollution filtration and gas humidification at the same time;
Atomization treatment: Atomized brine storage is built-in hidden and large storage capacity, brine is equipped with preheating function; quartz brine filter element is equipped before the brine is atomized to avoid nozzle impurities clogging the terminal test;
Pressure control: through intake pressure regulating valve, spray pressure regulating valve, pressure gauge; air pressure is 1Kg / cm2 divided into two stages: one stage is roughly adjusted 2Kg / cm2, using imported air filter, with drainage function, two stages For precise adjustment of 1Kg / cm2, 1/4 pressure gauge, display precision and accuracy, pressure value: front inlet pressure: 0.3-0.6mp, rear spray pressure: 0.07-0.17mpa; Attachment 1: salt spray test box Purchasing requirements: Exhaust pressure: ≥8 kg volume flow: ≥0.12m3 / min. Attachment 2: The LRHS series salt spray test chamber has an automatic defogging device. The gas generated by the air compressor enters the working room to disperse the excess mist. The gas is discharged through the exhaust hole on the back of the box to make the box cover Without fog and condensed water, the corrosion status in the working room can be clearly observed.

Lip gloss was invented by Max Factor in 1930. He wants to develop a lip product that can make the lips of the film bright and shiny. Inspired by movie actresses, women began to follow this makeup trend, leading to the popularity of lip gloss.
The earliest commercially available lip gloss was Max Factor's X-Rated4, which was launched in 1932. The original formula was sold until 2003.
Similar to Lipstick, lip gloss is a mixture of waxes, oils, esters and pigments.
The difference between lip gloss and lipstick products is the bright, transparent, or translucent cover layer. Generally, the ratio of oil component/wax component is relatively high, and the pigment content is relatively low (0~5%).
Lip gloss comes in many forms and used in different ways. It can be packed in a small cylinder and applied with a round or inclined applicator stick or built-in Lip Brush; it can also be packed in a soft squeezable plastic tube, which can be passed through the nozzle or with your fingertips or Apply with lip brush.
The basic lip gloss will only add gloss to the lips without discoloration. Color lip gloss adds color and gloss. Shiny lip gloss has a bright undertone, with or without color.
