] The test report should include the following: (1) (2) (3) (4) (5) The effective water area of ​​the sample; Geosynthetics vertical permeameter [Instructions]: 1. Place the sample in water containing humectant and soak for at least 12 hours until saturated and remove air bubbles. The humectant used 0.1% V/V sodium alkyl benzene sulfonate. 2. Remove the high pressure chamber (see Figure 12 between the instruments) and install the test piece (5) on the holder (6). The sample requirements: the sample should be clean, the surface is free of dirt, no visible dirt or creases, and must not be folded. It should be placed in a flat place and no load should be applied to it. Then install the high pressure chamber and tighten the high pressure cylinder nut in equilibrium. 3. Open the water valve (3) and (1) inject the clean water source into the high pressure water tank (2). Until the water level on both sides reaches a head difference of 50mm (11). Turn off the water supply. If the water heads on both sides of the sample are not balanced within 5 minutes, look for unclean air. Open (13) the exhaust valve to re-vent. And noted in the test report. 4, adjust the water flow, so that the head difference reaches 70mm ± 5mm, record this value. Accurate to 5, respectively, the maximum head difference of 0.8, 0.6, 0.4 and 0.2 times the head difference. Repeat the procedure in 2.3.4 above, starting with the highest flow rate and ending with the lowest flow rate, and record the corresponding amount of permeate and time. 6. Record the water temperature to the nearest 0.2 °C. 7. Calculate the results according to the corresponding standards of T1141-2006. After the vertical penetration test of the geosynthetic material is completed, the drain valve (4) is opened, and the water of each part is drained. Clean the surface of the instrument.
·Basic precautions
Do not put expensive oil into low-quality cartridges to avoid wastage. Most pre-filled oil cartridges have the so-called 510 thread. The oil cartridge screws onto a rechargeable battery. Some of these batteries have buttons and some heat up automatically when you pump the oil. Some batteries have multiple temperature settings and some heat up to a preset temperature; these features need to be known in advance.
·Cleaning notes
Use a suitable cleaning tool to clean them, such as activated charcoal or dried tea leaves in a used pipe to absorb the oil. It is important not to use alcohol or other boiling water to clean the pipe, and to wait until it has cooled down completely before cleaning. Otherwise, the hot stem will come into contact with the watery liquid and cause the mouthpiece tenon to loosen, thus shortening the life of the 510 cartridges.
This is what you should be aware of when using 510 cartridges. At the same time, when using 510 cartridges, there are still some vaping tips, for example, when using them, be careful not to suck too hard, will not produce smoke. When you inhale too hard, the smoke is sucked directly into your mouth and not atomized by the atomizer, so gently inhaling is more powerful and gives you a better vaping experience.
