The reasons that affect the results of the ultraviolet weather resistance test chamber are:
1. Surface pollution: Dust and other surface pollutants will seriously change the absorption characteristics of the surface of the illuminated object. Unless otherwise specified, the sample should be clean during the test, but when evaluating the effect of surface contaminants, the relevant specifications should specify the necessary content of the sample surface treatment;
Second, the temperature in the box: the temperature during the irradiation stage or the shutdown period should be controlled by the prescribed test procedures (A, B or C), and the relevant specifications should specify the temperature to be reached during the irradiation stage according to the intended use of the equipment or component 40 degrees or +55 degrees;
3. Humidity in the box: under different humidity conditions, the photochemical degradation effects of various materials, coatings, plastics and other substances vary greatly, and their requirements on humidity conditions are different from each other, so the specific humidity conditions are clearly defined by the relevant regulations Regulations. For example, the prescribed test procedure B is executed in the first 4h of each cycle according to the humid and hot conditions (40 degrees, relative humidity 93%).
4. Airflow speed: The size of the airflow speed near the surface of the sample in the ultraviolet weather resistance test box not only affects the temperature rise of the sample, but also causes significant errors in the open thermoelectric stack that monitors the radiation intensity. Generally, the speed of 1m / s causes the temperature rise of the thermopile to decrease by more than 20%. It can be seen that while effectively controlling the temperature (or) conditions in the box, the airflow speed should be monitored, and the lowest speed should be used as much as possible. In addition, when adjusting the temperature in the box, high-speed airflow can be avoided by heating or cooling the box wall. In the natural environment, the probability of the occurrence of strong solar radiation and the special condition of zero wind speed is extremely small, so when it is necessary to assess the impact of different wind speeds on samples of equipment or components, the relevant specifications should specify specific requirements;
5. Ozone and other polluting gases: the ozone generated by the box under short-wave ultraviolet radiation of the light source can usually be discharged out of the test box through a radiation filter that corrects the spectral energy distribution, because ozone and other polluting gases will affect certain materials Unless otherwise specified in the relevant specifications, these harmful gases must be discharged out of the tank;
6. Bracket and its installation: The thermal characteristics and installation methods of various brackets will have a serious impact on the temperature rise of the test sample. Full consideration should be given to this so that its heat transfer performance represents the typical actual use. During the test, the samples are mostly installed on various elevated supports or cushions that specify the thermal characteristics. The detailed requirements for cushions and their installation methods and the placement of samples should be related to the regulations.
Every woman strives to look stylish and beautiful, regardless of the weather outside, the time of year or the dollar exchange rate.
Not everyone is ready to immediately go on the operating table, so let's figure out what effective methods of rejuvenation exist today.
For clarity, let's take drugs based on polylactic acid. For more than 20 years, this acid has been successfully used in medicine as a suture material for surgical threads and pins, and it has been very well studied. The main effect of the procedure is stimulation of the production of your own collagen, which replenishes the volume of soft tissue lost with age. The main value of Reborn polylactic acid is to provide the body with signals about various damages and further continuous formation of new collagen.
Over the course of several months, the drug biodegrades and is eliminated from the body, but in its place what remains is not emptiness, but collagen and elastin.
That is why the effect of Reborn PLLA injections lasts for up to two years or longer!
Reborn PLLA Dermal Filler offers an unassuming yet significant transformation. It's not about completely altering one's appearance but rather about accentuating and reviving what's already there.
