The current disinfectant used in swimming pools is isocyanurate chloride which is a chlorinated derivative of isocyanuric acid. Hot Tub Test Strips,7 In 1 Test Strips,Test Hot Tub,Test For 16 In 1 Jilin Test Bio-Electron Co., Ltd , https://www.tst-check.com
The most prominent characteristic of isocyanurate chloride disinfectants is that the process of disinfection can produce hypochlorous acid stabilizer - cyanuric acid.
Cyanuric acid is hydrolyzed by chlorine binding to release hypochlorous acid, resulting in a long-lasting disinfectant effect.
The concentration of cyanuric acid plays a key role in the effectiveness of disinfectants.
However, because cyanuric acid is not easy to decompose and remove, it is easy to gather in water. When its concentration increases to a certain extent, it will combine with the residual chlorine in water and reduce the residual chlorine concentration, which will seriously inhibit the disinfection effect of hypochlorous acid.
When the concentration of cyanuric acid in water is too low, it cannot effectively stabilize chlorine, hypochlorous acid will quickly decompose and lose its disinfectant effect under light.
The air cleaner and pressure regulator PCV are easily overlooked when routinely servicing the vehicle. Moreover, it is often the case that when they become clogged and endanger the normal operation of the engine, they will be replaced and replaced. In order to avoid premature engine wear (abnormal) and to maintain the best working condition, the air filter and pressure regulator valve PCV regular inspection and replacement is crucial. We emphasize that preventive maintenance of air filters is not an exaggeration. The air cleaner filters out airborne dust, carbon and other debris before the air is mixed with the fuel, thus ensuring clean air intake. In fact, about 10,000 units of air are required to pass through the filter per unit volume of fuel burned. And then the tiny particles of dirt can lead to serious wear and tear of the engine related internal components. Normally, the manufacturer recommends that the replacement interval of the air filter be maintained at 48,000 km and that it be routinely checked every 24,000 km. The recommended replacement period for conservative maintenance is 24,000 km. The atmosphere contains three basic particulate pollutants of different densities, namely dust, debris and carbon particles. On open freeways, its dust content is lower than in rural and built-up areas. In areas with a high dust concentration, the air filter should be tested and replaced more frequently. In highways and areas with heavy traffic, carbon levels in the air are significantly higher because of the concentration of car emissions. In the daily replacement of oil, incidentally check the air filter after all, is a good way to get the best of both worlds. At this point, take the filter and carefully examine the inner depths of its folds. Occasionally, the exterior of the filter appears to be clean, but its interior is already so dirty that it must be replaced immediately. The PCV system introduces the mixture of blowby into the crankcase into the intake system and then the secondary combustion in the combustion chamber. Over time, oil, gasoline, and other condensate deposits inside the PCV valve into a sludge gel that clogs the PCV valve and increases the gas pressure inside the crankcase. This pressure build-up causes oil to leak from the seal or gasket, causing additional oil and engine leaks. In addition, increased pressure on the crankcase allows PCV vapor to pass through the air filter, which sticks to the oil and HC compound particles, which inevitably reduces its proper filtration accuracy. When the foreign matter sticking to the PCV can not be completely shut down, an inappropriate amount of air will be introduced into the combustion chamber, which in turn dilutes the air / fuel mixture, eventually leading to deterioration of the idle speed of the vehicle and flameout. The recommended replacement cycle for PCV valves provided by most manufacturers is 96,000 km. The conservative maintenance cycle is 48,000 km. In any event, be sure to check that the PCV valve is clogged and bonded while checking the air cleaner. The recommended replacement cycle for Ford PCV valves ranges from 9.6 to 160,000 km depending on the specific models. General Motors also offers the recommended replacement cycle for PCV valves based on different models, with a wide range of values. When you have doubts about the PCV valve change intervals for the vehicle being serviced, please consult the owner's manual or repair information in good time.
