　　There are many steps in makeup, and the makeup tools used in different steps are different. For example, when painting eye shadow, eye shadow brush will be used, and when concealing, concealer brush will be used. So, can the eye shadow brush be used as a concealer? Concealer brush is harder than eye shadow brush, and the brush head is smaller. Concealer is generally paste, but eye shadow brush is not suitable. Let’s learn more about the difference between concealer brush and eye shadow brush.It is strictly required by such a standard, makeup brush set Only with today’s development scale, can we have the proud momentum to crush our competitors. https://lsmakeupbrush.com

　　First, can the eye shadow brush be used as a concealer brush?

　　The eye shadow brush can’t act as a concealer. The concealer brush is to dip a proper amount of cosmetics, that is, concealer liquid foundation, etc., and then smudge the edge of the concealer, remember to use it a few times. The material of eye shadow brush is not suitable for concealer.

　　Eyeshadow brushes can be roughly divided into five types according to the size of the brush head. Generally speaking, the color brushed by the big brush head is relatively light, which is suitable for a large area of eye socket, and the middle brush head is used to brush the middle color. People with deep double eyelids can get eye shadow on the wide side of the brush. Eyeshadow brush with pencil brush head is generally a necessary tool to draw a gradual feeling at the end of the eye. Small flat brush with long hair is mainly used to enhance the effect of key colors.

　　Second, the difference between concealer brush and eye shadow brush

　　1. In terms of softness and hardness, concealer brushes are generally hard, while eye shadow brushes are softer; In terms of brush head area, concealer brush head is smaller, and eye shadow brush head is bigger; In terms of usage, if you choose a concealer brush, you should adopt a point painting method, and if you choose an eye shadow brush, you should adopt a horizontal painting method.

　　2, concealer brush is mainly used to cover a small area of the face, emphasizing accuracy, so the concealer brush is hard, which is more convenient to apply. The eye shadow brush is used to apply eye shadow, which needs to be applied repeatedly on the eyelids. If the brush head is too hard, it will hurt delicate skin, so the bristles of the eye shadow brush are particularly soft.

　　3. When you need to retouch your makeup, you can dip a small amount of liquid foundation and concealer with a concealer brush and gently apply it to acne marks and other parts. In order to make the concealer and the base makeup blend together better, you can gently wipe the border with a cotton swab, so that the concealer can smudge better and blur the dividing line.

　　4. The brush head of the eye shadow brush is generally larger than the concealer brush, but there are many kinds of eye shadow brushes, and each eye shadow brush is used to apply different parts. Eyeshadow brushes with large area and flat shape are generally used as a base, which can ensure that the edges and corners are taken care of. You can dip it in white or beige, and then apply it across the entire eyelid. A small flat eye shadow brush is generally used to highlight the main color, and is usually used to smear the middle of the eyelid. Eyeshadow brushes with small area and sharp shape are generally used to repair or outline.

　　5. Concealer brush and eye shadow brush have their own strengths. If you want to create a perfect makeup, it is best to buy them together. And whether it is a concealer brush or an eye shadow brush, remember to clean it in time after use, so as to ensure that you still have a clean beauty brush next time.

Adult progressive lenses can greatly meet the needs of presbyopic people to see both near and far with one pair of glasses.

　　However, progressive glasses have high requirements for fitting, and how to accurately and quickly measure the key fitting parameters – channel and ADD, has troubled many colleagues in optical shops. At this year’s Shanghai exhibition, a very practical tool was discovered that can quickly and accurately measure the progressive channel.

　　What is a progressive channel?

　　Simply put, the channel is the transition length of the progressive lens from far to near. Proper channel selection is one of the key factors in whether the progressive lens is comfortable and convenient to wear.

　　Note: The channel length of progressive lenses of different brands is different, so please ask clearly when ordering! Example: The channel length of Zeiss progressive lenses is the vertical distance from the fitting cross to the starting part of the near area.

　　When the distance diopter and ADD are determined, the longer the channel length, the smoother the change from near diopter to distance diopter. However, when selecting a long channel, the downward rotation ability of the eye should be considered. Insufficient downward rotation force can easily cause unclear near vision.

　　Tools Recommendation | Rapid Calculation of Progressive Channel

　　How to accurately measure the length of the progressive channel? Measure the position of the pupil on the support piece when using it for distance and near respectively, and then measure the vertical distance between the two.

　　Is it better to have a multi-core cable or a single-core cable? The difference between single-core cables and multi-core cables. Power cables are generally divided into single-core, double-core and three-core cables. Among them, single-core cables refer to cables with only one conductor in one insulation layer, while double-core cables refer to cables with two conductors in one insulation layer. In fact, both have their advantages and disadvantages. For example, when the line of a single-core cable is long, when the control circuit with a large current is used or when it is laid in water, in order to prevent or reduce the middle connector, or when single-core cables have better comprehensive safety engineering than multi-core cables, single-core cables can be used.To get brand praise, shielded twisted pair cable It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://www.linkcablecn.com

　　Is it better to have a multi-core cable or a single-core cable?

　　1. From the current point of view, the current passing through a multi-core cable with the same cross-sectional area is relatively larger than that of a single-core cable, and the load is large.

　　2. From the perspective of power loss, the two ends of the single-core cableare directly grounded, and the metal shielding layer of the cable may also generate circulating current that can reach the current carrying capacity of the cable, which wastes power and forms loss. Multi-core cables are generally three-core cables, because during the operation of the cable, the sum of the currents flowing through the three cores is zero, and there is basically no induced voltage at both ends of the cable metal shielding layer.

　　3. From the perspective of cost, among the wires of the same cross-sectional area, the cost of single-core cables is cheaper than that of multi-core cables, and multi-core cables are slightly more expensive.

　　4. From the perspective of installation, single-core cables appear harder when passing through pipes, while multi-core cables are softer and easier to wire.

　　2-core cables: When the neutral line of 1kv and below power supplies is directly grounded, the number of cable cores of the single-phase control circuit should be 2-core cables when the maintenance line and the neutral point share the same conductor. For control circuits that can be powered by DC, 2-core cables should be used.

　　3-core cable: When the neutral line of 1kv and below power supply is directly grounded, the number of cable cores of the single-phase power control circuit is: When the protection line and neutral point are separate, it is advisable to use a 3-core cable.

　　4-core cable: 1kv and below 4-core cable (3+1 cable), in which the fourth core is used as a grounding protection, and also carries the unbalanced current and short-circuit capacity of the power supply system. (To learn more about cable technology, please click here, a lot of dry goods are waiting for you) Its size is determined by the unbalanced current and short-circuit capacity, but generally cannot be less than 1/2 of the phase line.

　　5-core cable: 1kv and below three-phase four-wire distribution room system, some electrical equipment distribution lines with higher safety requirements, and some communication centers and automation equipment that must ensure power safety and anti-interference grounding, it is advisable to use 5 copper core cable TN-C distribution room system, so that the protection line (PE line) and neutral point (PN line) are independent, and the cable core section is generally 3 large and 2 small or 4 large and 1 small or 5 large.

　　Multicore Flexible Cable supplier.jpg

　　The difference between 4-core cable and 3+1 core cable: 1kv and below three-phase four-wire distribution room system, when the protection line and neutral point share the same conductor, 4-core cable should be used, and the method of 3-core cable plus single-core cable to form a circuit cannot be used, or even the method of directly using the metal sheath or armored cable layer of 3-core cable as the neutral point. Otherwise, when the 3-phase current is unbalanced, it is equivalent to the operation of a single-core cable, which is easy to cause DC interference.
