    Polyvinyl chloride, better known as PVC, is a very common thermoplastic material. It is known for its durability and excellent flame, chemical, and abrasion resistance. PVC exhibits good dimensional stability, and high resistance to weathering and impact, as well as good dielectric properties. Tensile strength is roughly 6,500 psi.   PVC thermoplastics are available in range of durometers, from soft and flexible to hard and rigid, which makes the material a good choice for a wide range of applications. All PVC types/grades exhibit excellent dimensional stability, making them ideal for injection molding.   Understanding PVC Processing in Plastic Injection Molding Polyvinyl Chloride or PVC is one of the most popular industrial thermoplastics chosen to create a variety of plastic products. These include pipes, medical tubes and containers, electrical cables, and construction vinyl siding. As this material is in great demand, manufacturers need to follow a systematic process when desig

  Belt support is also called waist belt, waist support, lumbar support, waist circumference. An introduction to the belt The waist protection belt is generally composed of a breathable waist protection net, high elastic elastic fabrics and reinforcing belts on the left and right sides, and a steel strip or resin strip on the back. Its main function is to protect the lumbar spine and relieve and relieve pain by restricting the movement of the waist. The fundamental reason is that the back steel strips and elastic bands limit the flexion movement of the lumbar spine, relieve the pressure in the lumbar intervertebral disc, and enable the injured intervertebral disc to get adequate rest. , to prevent the aggravation of the injured waist and create conditions for a better recovery. Second, how to choose the belt? 1. Choose a well-known brand with a good reputation If you want to buy products from well-known brands, especially those from professional protective gear companies, don ’ t try t

  1. In order to manufacture a high temperature water tank of the same volume, the weight of the FRP water tank is only 1/4 of the steel water tank and 1/15 of the reinforced concrete water tank, thereby reducing the weight of the water tank, reducing the load of the building structure and reducing the construction cost. 2. The FRP water tank has good waterproof and anti-corrosion properties. It does not leak like a reinforced concrete tank, nor does it require repair, painting and corrosion protection like a steel tank.   3. The  FRP water tank   can be molded and assembled on site. After the water tank is changed, the nozzle and drain pipe of the water tank can be completed. It does not need to increase the manufacturing cost of traditional water tanks, nor does it need to increase the anti-corrosion process of oil and gas such as steel water tanks.   4. FRP water tanks can withstand 8 earthquakes without damage, while steel water tanks and reinforced concrete water tanks cannot resi

    Tricalcium phosphate  is a supplement form of calcium phosphate and is used to treat or prevent calcium deficiency. Calcium is primarily important for healthy bones and teeth. Calcium is naturally found in foods like dairy, nuts and seeds, and dark, leafy vegetables. In addition to its use as a supplement, tricalcium phosphate is used as an anti-caking agent in powdered food items. It is also used as an additive in some processed foods to boost calcium content.   Is it safe? Tricalcium phosphate is a calcium salt found in many nutritional supplements. It is considered safe to use as a food additive and supplement, but there are some people in whom it has contraindications, and there can be interactions and side effects. Many people wonder about the safety of tricalcium phosphate, including side effects and whether it causes cancer. Some people take supplements containing tricalcium phosphate to supplement their daily calcium intake if they are not getting enough calcium from diet a

    1. What Do Pipe Threads Need Protection From? When connecting any section of pipe to another, thread engagement will determine the strength and seal quality of the string. The thread profile and pipe specification will determine the axial loading that a specific section can handle. To ensure every connection works optimally,  pipe thread protectors  can reduce the risk of a compromised thread profile. The types of elements that pipe threads need protection from include: • Corrosion and rust when exposed to the elements • Debris and moisture • Contaminants that could reduce the quality of the extracted fluids • Damages like scratches, dents, cracks, and dings Corrosion particularly presents a problem for operators, as it may not be easily visible before installation. Contaminants and moisture in the thread may increase the speed of oxidation, leading to a compromised thread profile. Any damaged thread will likely also accelerate the corrosive chemical reactions in the connection dur

  The EPS foam molding machine has the characteristics of complete functions and convenient parameter adjustment. Closed mold, feeding, foaming, mold, gas and automatic control, but also allows computer control to produce foam products with multiple heating methods Old machine molds that can be used in complete soil environments, in the case of no changes in plants, the The machine can be in good condition, so that the products meet the requirements of automatic vacuum forming machine. The foaming machine has compact structure, space saving, reliable performance, convenient maintenance, labor saving, steam quality saving, and raw material saving.

The foam molding machine adopts imported hydraulic system at the same time, and increases the clamping force to improve the speed of the mold, the molding cycle is short, the molding machine is automatic molding machine More energy-s

  The butterfly valve is a type of one fourth-turn rotary motion valve which is used as a throttling valve to control and regulate the flow through a system. Butterfly valve has its own set of advantages which include good control capabilities, quarter-turn, and openness for diminished plugging systems. Further, the capability of butterfly valves to work in areas with limited space and deliver a high coefficient of flow makes them an important part of industries today. However, since it is difficult to clean their internal parts, they are not recommended to be used in industries like medical and food processing applications where sterility is an important factor.     CONTROL METHODS OF BUTTERFLY VALVES Butterfly valves  function by controlling the flow of the liquid that passes through them depending on the method of control. A butterfly valve consists of a metal circular disk, also called vane. This disc pivots at a right angle to the axis of the direction of flow in the pipe. When th
