Fatigue resistance of steel fiber compared with ordinary concrete, the flexural and compressive fatigue properties of steel fiber reinforced concrete are greatly improved. For example, when the bending fatigue life is 106 times, the stress ratio of steel fiber reinforced concrete with 1.5% fiber content is 0.68, while that of ordinary concrete is only 0.51. When the stress ratio is 0.7, the bending fatigue life of steel fiber reinforced concrete exceeds 105 times, while that of ordinary concrete is only 850 times. Another example is: when the compressive fatigue life of steel fiber reinforced concrete with 2% fiber reaches 2*106 times, the specific force can reach 0.92, while the stress ratio of ordinary concrete is only 0.56. It can be seen that the use of steel fiber reinforced concrete can significantly improve its fatigue life in projects bearing fatigue loads such as pavement and pier. Star Smith is a professional steel fiber manufacturer that can offer a wide range of steel fibre types that meets different needs.

All in one integrated solar street light is composed of high efficient solar panel; detachable Philips Lumileds modules; soft lithium batteries and a smart controller. During the daily use, the charge controller will first turn off the integrated solar street lights towards dawn once the solar panel's voltage rises to 5v, which is accounted for a little sunlight in the morning. When there is enough sunshine during the day, the solar panel will work together with the smart controller to collect the solar energy. Commonly, in a 12v solar system, with the effect of insolation, the voltage of the solar panel will rise to around 18v so as to charge the 12v battery bank. Meanwhile, the solar charge controller of the all-in-one integrated solar street light will prevent overcharge to protect the batteries. When there is not enough sunlight towards dusk and solar panel voltage drops to a value under 5v, the LED solar integrated lamp will be turned on accordingly. “Time control mode” and“Motion sensor control mode” will be working during discharging at night(12H). Normally our engineer recommend you to use‘444’ or ‘66’ two kinds of diming. Relative to the price, the price of an integrated street light is often cheaper than a set of split lamp systems. SOKOYO is a professional solar lantern manufacturers, we provide solar street light integrated, 60w all in one solar street light, integrated solar street lamp with radar sensor, solar led street light all in one, all in one solar street light with camera, led solar integrated lamp, integrated street light and etc. Want to know more?please contact us.

The backward pumping kneading block plays a role of adjusting the fullness of the material and extending the residence time of the material in the barrel during the material mixing. Its blocking force is weaker than the reverse feed screw sleeve, but slightly stronger than the 90 ° kneading block. Which area should choose the backward pumping kneading block? How to use it with the reverse screw sleeve in the full length? How many reverse elements should be selected for the full length of the screw? All of these questions are testing the experience and skill of the modification engineer, which has a considerable impact on the quality of the modified special material or masterbatch. For example, in the case of nylon (PA66) flame retardant enhanced modification, the first kneading zone must be stringed by four kneading blocks (such as 30 ° + 45 ° + 45 ° ++ 45 ° L), and must be finished by 45 ° L blocks Stuffing, the whole machine can stably plasticize and stably extrude the PA66, a strong crystalline plastic.

PTH Hole in PCB / PTH PCB There are three common types of drilled holes in the printed circuit board: PCB through hole plating , blind via hole, and buried via hole. Therefore, PCBs are classified according to drilling methods and can be divided into plated through-hole PCB, blind via hole PCB, and Buried via hole PCB. PTH is the most common drilling method, and it is common in various types of PCBs. SPEEDAPCB has been focusing on the production of various PTH (plated through hole PCB-PTH PCB), buried via hole PCB and blind via hole PCB. HAVE A QUESTION OR REQUEST? Click below, we’ll be happy to assist. Drilling Method of Plated Through Hole PCB Plated Through Hole, the copper foil lines between conductive patterns in different layers of the circuit board are connected or connected with this type of hole, but the copper legs of the component lead or other reinforced materials cannot be inserted. The PCB is formed by the accumulation of many copper foil layers. The copper foil layers cannot communicate with each other because each layer of copper foil is covered with an insulating layer, so they need to rely on via for signal connection. The through hole of the circuit board must pass through the plug hole to meet the customer's needs. In changing the traditional aluminum sheet plugging process, the solder mask and plug hole on the circuit board surface are completed with a white net to make its production more stable and the quality more reliable , More perfect to use. The vias help the circuits to be connected to each other. With the rapid development of the electronics industry, higher requirements are also placed on the PCB manufacturing process and surface mount technology. The plugging process for vias came into being, and at the same time, it must meet the following requirements: 1. Only copper is required in the hole, solder plug can be plugged or not; 2. There must be tin-lead in the hole, with a certain thickness requirement (4um), to avoid solder mask ink entering the hole, causing tin beads to be hidden in the hole; 3. The through hole must have a solder resist ink plug hole, opaque, no tin rings and beads, and must be flat. Through-hole boards are common in all fields and are one of the most common PCBs. Generally, the mobile phone board or PDA board has a board that uses a combination of blind and buried holes. The buried hole can reduce the probability of signal interference, maintain the continuity of the transmission line's characteristic impedance, and save routing space. Circuit board design. This type of board requires high technical content and accurate accuracy, so relatively speaking, the requirements for factory equipment are much higher than ordinary multilayer boards, and the cost of such circuit boards will be much higher than ordinary Shelf should be high.
