  1.   How to stop leaks of high hydrostatic pressures with Boyu waterproof Acrylate Gels (Acrylic Gel)?   Water ingress Waterproof Resin Coating can escalate project costs and lead to many other problems. The use of injection systems based on dual and single component polyurethane and acrylate resins are cost-effective and provide a high success rate.   Appropriately engineered resin injection does not only seal leaks in the structure itself, but can transform loose sands to the consistency similar to sandstone and gravel to a solid conglomerate.   What are Acrylate Gels?   Acrylate Gels, also known as Acrylic Gels, are very flexible, super low viscosity — similar to water — hydrophilic gels designed for non-structural injections of cracks, joints, voids, and used for grid, curtain, bladder injection and as sealant in the injection tube system. works. Due to their extremely low viscosity and low surface tension, polyacrylate gels offer superior penetration properties. Acrylates are gel time adjustable to meet jogbsite conditions such as temperature and injection distance. Acrylic gels are used to waterproof leaks and create a compression seal due to their hydrophilic swelling behavior when in contact with water.   Acylate injection equipment can easily be cleaned with water.   Boyu waterproof provides a wide range of products to control water ingress into underground mining works, tunnels and many other commercial structures with leakage issues. We supply materials for waterproofing, consolidation, sealing, crack and joint repair, bonding and cavity filling.   Will I need more than One Product?   That depends on the jobsite. There is no single resin that will suit all conditions. The correct resin must be used to achieve the best results possible and to meet the requirements of the specification. Polyurethane and Acrylate injection systems offer a variety of solutions to problems found in geotechnical applications, in tunneling, waterproofing underground works and civil engineering in general.   How to Start Acrylate Injection Leak Sealing Injection Repairs   The principal steps to solve a problem are:   Diagnosis of the problem   Specification of injection methods   The correct choice of resin, pumps, packers and accessories   Training of installation personnel, a well trained and experienced team is paramount.

  2.   Relubricating the bearing grease is of great importance to ensure the longevity of your ball- and roller bearings. Bearing grease provides a smooth process with as little friction as possible. Bearing grease is also necessary to avoid direct contact between the rolling elements and their treads.   Contents   Regular grease lubrication   Tools and resources for your application   Application methods for bearing grease   What method works best for you?   Manual vs. automatic lubrication   Common mistakes and guidelines   Regular High Pressure Grease Fitting lubrication   Most applications require that you relubricate or replenish your bearing grease. Though the bearing grease stays put and barely leaks, old grease can dry out eventually and therefore be less effective. This is ecause the base oil spreads out over the moving parts of the bearing and the thickener vaporises through the heat.   How you replenish or renew your bearing grease depends on the application it is used for. Occasionally a machine has a built-in ‘replenishing mechanism’ which makes lubrication quick and easy.   Tools and resources for your application   If you wish to manually apply your bearing grease, there are certain tools available. These tools ensure that you work cleanly and can distribute the bearing grease precisely and evenly.

  3.   High Pressure Grease Fitting Basics   The packer and the drill holes must be of a quality that withstand the injection pressures without leaking or moving inside the crack. Caution: Even the best packer may break lose or pressure leak in some circumstances. Mechanical Packers are the recommended choice for pressure injection. They come in many sizes and designs to suit your job. Mechanical packers have a threaded shaft with a rubber base. Following insertion, tightening of the threaded shaft will compress the rubber inside the drill hole, resulting in a compression seal. Typical diameters of these packers can range from 1/4–3/4 inches with industry standards being 3/8–5/8 inches. In poured concrete substrates, the drill hole will act as a solid channel which will direct the resin to the crack which permits the usage of shorter length packers. In substrates which may exhibit voids such as block wall, stone and brick, recommends using longer packers which provide a definite grout delivery channel to the crack being sealed.   Mechanical Packers Installation   Mechanical packers are tightened to seal against the drill hole by expanding the rubber seal. You may pre-tighten the packer by hand to snugly seat the rubber all the way (approximately ¼”/5mm) inside the drill hole. Correct installation will prevent concrete from cracking around the outside of the drill hole. Depending on the packer design it is highly recommended to use a suitable ratchet/nut or wrench to tighten the packer. Electric drivers are also popular. Tighten packers securely to withstand injection pressures! But do not over tighten.   Hammer-In Ports   Hammer-In Ports are also commonly used. Seat the ports with a hammer at moderate force. An electric driver or hand tool and suitable socket are used to screw the zerk fitting into the port. In most applications, hammer-in ports do not achieve the same injection pressures as mechanical packers and should only be used where maximum injection pressures are not necessary.   Packer Connectors   Typically packers are equipped with a quick connect system which is either of a zerk type or button head / slide coupler type.   Type Connector   The zerk type is most common. The applicator has to push the coupler over the zerk fitting and hold it in line with the packer. To disconnect the applicator “breakes” the connection by pushing the connector sideways.   Button Head / Slide Coupler   The button head type offers the most secure connection. The operator slides the coupler on and off the packer which makes the connection very secure, tight and less prone to unexpected disconnection and leakage. When done correctly the applicator does not have to hold the coupler in place. This is a big advantage in over-head injection and where large volume of product has to be pumped through one packer.   Packers   supplies an industry leading selection of injection packers and ports for all situations and needs. Please contact a representative to recommend the right Brass Injection Packers for your job.   Flushing the Cracks Prior to Injection   It is recommended and very good practice to flush dry and not actively leaking cracks with water prior to injection. Flushing removes debris, indicates material flow, expected product penetration distance and provides moisture for the product to react with. If the crack is not accepting water, your hole may not be connected to the crack. In this case, drill from the opposite side of the crack and water test again. Flushing should be performed at lowest pressures possible to avoid damage to the concrete. Flushing is not always possible as the required equipment may not be available. In most cases, the injection will be successful without introducing extra water. Even if the product does not come in contact with water immediately, it will cure over time as natural moisture in concrete will stimulate a cure and hardening, possibly at a delayed pace.   Flushing Water Pump   For flushing, it is recommended to have a dedicated water injection pump on site. Never water test with the same pump from which polyurethane resin will be dispensed. Polyurethanes are water activated and even small traces of moisture can cause pump failure.
  4. Rough idling or slow starting are signs that the engine isn’t firing properly and that the injectors could have issues.   If your engine is running at lower-than-normal RPMs, you should have the injectors looked at. It’s a good indication that your engine isn’t getting the power it needs, which could be due to issues with the Polyurethane injection grouting system.   If you notice your fuel efficiency getting worse, that is a real sign that there are problems with the fuel injectors. When they are working as they should, your fuel efficiency should be near the top performance that you can expect. Fuel efficiency really suffers when there are problems with the injectors.   Another warning sign is the smell of fuel around your car. When the cylinders aren’t getting enough fuel due to a clogged or damaged injector, the computer will send more fuel, which can add to the leak or buildup in the problem area.   On top of having your injectors looked at and cleaned as advised by the manufacturer, there are steps you can take on a regular basis to help keep them functioning at their best. You can keep an eye on your fuel efficiency and engine performance so you see warning signs of bad injectors right away as mentioned here.   Another thing you can do is add fuel cleaner to your tank. You don’t need to do it every time you fill up, but doing it on a regular basis will help keep your fuel system clean. This will help prevent buildup of fuel impurities in the injectors and in the fuel system as a whole.   How to Choose Fuel Injectors That Will Last   When it comes to purchasing fuel injectors, there are a lot of options out there to choose from. Opting for high-quality injectors will help you get more from the injectors and from your car’s performance.   The answer to how long fuel injectors last depends on a number of factors like the care put into your vehicle. It also depends on the quality of fuel injectors you choose.

  5.  The Polyurethane injection grouting may be a cementitious, resinous, or a solution chemical mixture. The grout is intended to fill the space and generally provide strength to the structure or geomaterials, depending upon location and design.   The most common grout used is cementitious, designed to fill and support concrete slabs on grade, fill sink holes, faults in masonry structures, concrete grade beams, support industrial steel tank bottoms, fill annular space of fiberglass pile repair jackets, tunnels, concrete dams, outflow structures, RCP pipe, etc.   Pressure Grouting Considerations   It is essential to understand soils and surrounding structures in order to select the proper grout viscosity, type of grout, and void filling characteristics. This process is very specialized; often requiring engineering study and design as well as proper equipment and an experienced specialty contractor to perform the installation. Location and depth of injection ports must be in accordance with the structure and properties of the grout to ensure proper grout filling. Pressure relief port are needed to monitor grout flow and allow air to escape.   Vertical Structures vs. Horizontal Structures   In vertical structures the grout injection must begin at the lowest point moving upward. In horizontal structures, grout injection must begin at one end from port to port until you reach the opposite end of the structure. Plugging ports as you inject is essential to maintaining grout pressure and prevent unwanted, internal voids.   Pressure Injection Grouting Manufacturers   There are several manufacturers of pressure injection grouting equipment who supply many different types of equipment designed for specific conditions. It is critical to select the right equipment that is compatible with grout characteristics, and the right contractor with specific experience with different equipment and materials. The pressure injection grouting process must follow all ASTM and ACI sections for quality assurance, testing, and longevity.   Additional considerations for every application:   Determine the approximate size, location, access and structural requirements, surrounding conditions, presence of water or contaminates, soil samples and site temperatures.   Identify if Injection Packers or non-shrink properties are required.   Will the concrete element require structural repair, cleaning, and or additional joint relief before pressure injecting grout?
  6. Reliable process sample accuracy can be a challenge for even the most experienced fluid system engineers and analyzer technicians. Often, identifying the cause of inaccuracies can feel like something of a guessing game, and the more time an issue takes to diagnose, the longer your operation may be losing money on product that is not up to spec.   Want more accurate samples? Here is a quick list of do’s and don’ts for better sample accuracy in your plant:   Do check for High Pressure Grease Fitting system errors. Sometimes the reasons for process sampling inaccuracy are easy to identify. Regularly audit your sample system to eliminate simple mistakes—things like reversed check valves blocking your sample flow, or a fast loop flowing backwards.   Do maintain sample flow. Successful sampling depends on ensuring the process sample fluid remains at the right flow, pressure and temperature to bring the fluid into an appropriate condition for analysis. Controlling those three conditions might be enough to eliminate many of the problems plaguing process analyzers around the world. Generally, a faster flow is recommended to ensure good sample mixing, cleaner sample lines, and quicker response time.   Do identify sources of time delay. Time delay refers to the total amount of time it takes for a sample to travel from the tap in the main process line to the analyzer. Too long a delay can negatively influence sample accuracy. Symptoms of an issue can include measurements that do not appear to be tracking with your process, muted responses, laboratory disagreement, and poor control scheme performance.   There are a few areas that can influence time delay, including the length of the sample probe, the line length and diameter of sample transport lines, too high or too low pressure in those same lines, and beyond. Unsure where to start? Do take advantage of third-party resources to help you uncover potential time delay sources.   Do reduce gas volume upstream. Gasses may run through the main system at high pressures, and they can ruin a well-designed sampling system. Not only can they cause time delay, as noted above, rapid decompression in the event of a component failure can also pose a safety risk. Therefore, it is a best practice to reduce the pressure of gasses as soon as possible in order to minimize sample system volume on the upstream side of a regulator.   Don’t choose incompatible materials. Fluids leave molecules behind after they touch a surface, and if your process sample loses too many molecules due to adsorption, your sample can spoil. Engineers should take care to select the proper materials for filter elements, regulator diaphragms, tube walls, or gas cylinders that minimize adsorption to improve sample accuracy.   Additionally, materials that are mismatched to your sample fluid may cause failures like sample leakage or even a blockage within the sampling device. Be sure to use compatible elastomer seals to ensure an accurate sample analysis.   Don’t sample from stagnant lines. Sampling from an active and flowing process line is essential to obtain an accurate sample. Remember: The timeliness of your sample is also dependent on the time it takes the sample to flow from the process to the extraction point. The location of the sample point can be a critical aspect of a successful sampling system.   Don’t design dead legs into the sample transport line. “Dead legs,” or lines containing an unpurged volume, can negatively impact process sample accuracy. These lines allow molecules to be held up from earlier samples that can diffuse into your current sample, causing a slow analyzer response and the continuous contamination of your Surface Packers system.
