Double sided scrim tape is made of high strength glass fiber yarn for strengthening the back material, coated with strong adhesion pressure sensitive adhesive on both sides; The double-sided scrim tape has high tension strength, strong viscosity, high wear resistance and moisture resistance. There is a thin layer of high temperature resistant glass fiber mesh cloth in the middle of the adhesive layer (glass fiber in a very wide range of temperature to maintain dimensional stability very little deformation) can provide vertical and horizontal two-way stable size without deformation. Adhesive materials range is very wide, including rubber, PP/PE, PBT/PET, ABS, PMMA, general plastics, metals, inorganic glass and so on. The adhesive can be maintained in a wide temperature range (temperature range depends on the nature of the adhesive material and the weight of the load). Features of Double Sided Scrim Tape Use high duty fiber glass(PES/PVS) mesh cloth as backing Both sides coated with aggressive pressure sensitive adhesive Protected by gold glassine paper release liner Backing material has very good tensile strength Extremely high adhesion strength Can be removed with no glue residue & no de-lamination Excellent resistance to abrasion, moisture, high temperature Can easily conform to many irregular surfaces Double Sided Scrim Tape vs Paper Tape Double Sided Scrim Tape (or Double Sided Fiberglass Tape) Composition: Double-sided scrim tape typically consists of a strong fiberglass mesh (also known as scrim) embedded between two layers of adhesive. This construction provides excellent strength and durability. Double-coated scrim tape is commonly used in construction and building projects for applications such as mounting, bonding, and sealing. The fiberglass mesh provides reinforcement, making it suitable for heavy-duty applications where strength and stability are crucial. Key Features of the Double-sided Scrim Glass Tape: Strong adhesion on both sides. High tensile strength due to the fiberglass mesh. Resistant to tearing and stretching. Suitable for indoor and outdoor use. Paper Tape Composition: Paper tape is typically made of paper or a paper-like material with an adhesive coating on one side. It lacks the reinforcement provided by fiberglass mesh. Paper tape is commonly used in painting and drywall applications for tasks such as masking, taping joints, and covering gaps. It is designed to be easily torn by hand and is often used in situations where flexibility and conformability are more important than sheer strength. Key Features: Easy to tear by hand. Flexible and conformable to irregular surfaces. Suitable for indoor applications where strength requirements are moderate.

The auto sensor kitchen faucet works according to the principle of infrared reflection. An infrared emitting tube is installed near the bottom of the faucet, and the projection area of the emitting tube is just below the water outlet of the faucet. When people put hand under the water outlet of the sensor kitchen tap, the infrared receiving tube will be covered, and the microcomputer inside the faucet will receive the signal and send the water boiling command to the solenoid valve to release the water. When the hand leaves the bottom of the sensor kitchen faucet, the solenoid valve will receive a signal to close the valve, and the faucet will stop releasing water. Under normal circumstances, the waterproof time of the touch sensor kitchen faucet will not exceed 30 seconds, and the water flow is also controlled by auto flow sensor tap, which can greatly save water energy. Likegro's touch sensor kitchen taps are widely used in shopping malls, office buildings, rest stations and other areas with high quality, cost-effective prices, and perfect after-sales service, providing people with a lot of convenience. How Do Automatic Sensors Faucet Work? The automatic sensor water tap refers to the principle of infrared reflection. When the human hand is placed in the infrared region of the faucet, the infrared emitted by the infrared transmitting tube is reflected to the infrared receiving tube due to the blocking of the human hand, and the signal is sent through the microcomputer processing in the integrated circuit. For the pulse solenoid valve, the solenoid valve opens the valve core according to the specified command after receiving the signal to control the water from the faucetï¼?when the human hand leaves the infrared sensing range, the solenoid valve does not receive the signal, and the solenoid valve core is reset by the internal spring. Control the water from the faucet. Do Automatic Sensor Faucet Need Electricity? Induction faucets use AC or DC power supply and use infrared induction. In the induction area, the water will come in, and the water will be stopped when you leave the induction area. The machine is controlled by a microcomputer, and the optimal induction distance is determined according to the shape of the basin. No manual adjustment is required. Alkaline dry batteries (6V, 3V, 4.5V) are used for DC power supply. Likegro, as an excellent bathroom hardware manufacturers, offers a wide range of gold toilet seat hinges for you to choose from.

±-BBO (±-BaB2O4) is a negative uniaxial crystal which has large birefringence over a broad transparent range of 190nm to 3500nm. ±-BBO is an excellent crystal especially in UV and high power applications. The physical, chemical, thermal, and optical properties of alpha-BBO crystal are similar to those of Beta-BBO. However, there is no second order nonlinear effect in alpha-BBO crystal due to the centrosymmetry in its crystal structure and thus it has no use for second order nonlinear optical processes. Instead, alpha BBO is widely used for fabrication of polarizers, polarizing beam displacers, phase retarders, birefringent plates, and time delay compensators especially those for UV and high power lasers. Applications of ±-BBO Crystals High power Beam displacers for isolators. High power Polarizer Time delay compensators Advantages of ±-BBO Crystals High UV transmittance Large birefringence High damage threshold Here at OST Photonics, we value integrity, accountability, and punctuality. Our vision is to be the most professional and reliable supplier of crystal products in the world.

How to choose the LCD splicing screen and LED splicing display screen? When we are doing big display project, often LCD splicing screen and LED splicing display is the most two technologies, they two market share accounted for almost 80% of the whole industry, such as outdoor advertising screen, mall advertising screen, monitoring command screen, meeting screen can see their shadow. So what are the differences between them? How should we choose it? 1. The display technology is different The LCD splicing screen adopts the LCD display technology composed of LED back luminous, which is composed of the LCD layer backlight plate, etc., like our commonly used TV, computer display, mobile phone screen and so on are this kind of luminous technology. The difference is that the panel of LCD splicing screen has been industrial processing, which is relatively more durable and can meet the requirements of continuous boot. The LED screen uses light light beads composed of three primary color chips, consisting of individual lamp beads forming a unit board of different sizes to display the image.
