What are the advantages of inflatable water park equipment?

  Fu Litian is the hottest. This is the hottest time of the year. People with hot weather are prone to irritability, bad mood, poor appetite, and decreased physical health. I just want to find a cool and fun place, so what are the ways to easily pass this hot summer? An inflatable water park is a recent water park that is basically called an inflatable water park because the entire facility is made of PVC material and inflated. For example, in a traditional water park, an artificial swimming pool needs to be built. Inflatable water parks are simple and can be achieved using inflatable pools. An inflatable water park only needs one inflatable slide. Inflatable water amusement equipment has the incomparable advantages of traditional amusement equipment, and its flexible and changeable combination not only meets the investment of various scales of operators, but also meets the needs of consumers. The unique features make  small inflatable water amusement equipmen t popular among investors

Why INCOM RESOURCES Plant's Food Grade RPET can be trusted?

  What is Food Grade RPET: * PET is the packaging of choice for many of the world's food and beverages because it is hygienic, strong, lightweight, shatter-resistant, and preserves freshness. PET is a very inert material that resists attack by microorganisms and does not react with food, which is why it is widely preferred for packaging food, beverages and pharmaceuticals. The annual global demand for PET exceeds 20 million tons. * PET is one of the most recycled plastics in the world. With the emphasis on environmental protection and plastic recycling in many countries in recent years, the demand for Food Grade RPET is increasing. * The recycled PET bottles are crushed, cleaned, and then processed through a series of extrusion, solid phase viscosity enhancement and other processes to finally obtain the most stable and safest  Food Grade RPET .   Application of Food Grade RPET: * Food packaging: mineral water bottles, beverage bottles, food packaging boxes, food storage boxes, plat

The difference between hot dip galvanizing and cold galvanizing on the surface of Malleable Iron pipe fittings

    Malleable Iron pipe fittings , as important pipe fittings in water pipelines, are often in contact with water and air, so their corrosion resistance is very important. Malleable Iron pipe fittings are generally galvanized and rust-proof on the surface of the product. Galvanizing is divided into hot-dip galvanizing and cold galvanizing. So, how to distinguish between hot-dip galvanizing and cold galvanizing? From the appearance, due to the uniform cold galvanized layer, its surface is close to the billet, with a unique surface unevenness, and the billet has a smooth and bright appearance. Due to the phenomenon of electrical shielding, cold galvanized parts usually do not have a galvanized layer inside (except for special galvanizing processes). The zinc layer on the surface of the hot-dip galvanized pipe is thicker because the hot-dip galvanized layer is late and the fluidity of the zinc solution is poor. In addition, the surface of the hot-dip galvanized layer will oxidize to produ

How Proportional Valves Work and Their Types

图片
    Proportional valves in hydraulic systems are classified according to their main functions, and are divided into four categories: pressure control valves, flow control valves, directional control valves, and proportional composite control valves. Each type can be divided into two structural forms: direct control and pilot control. Direct control is used in small-flow and low-power systems, and pilot control is used in large-flow and high-power hydraulic systems to form an electro-hydraulic  proportional valve . ①  Proportional pressure valve: There are proportional relief valve, proportional pressure reducing valve, proportional sequence valve, which can continuously adjust the pressure. ②  Proportional directional valve: The input current determines the flow direction of the liquid flow, and the stroke of the spool is proportional to the input current. The directional valve is divided into two categories: with position sensor and without position sensor. ③  Proportional flow valve:

Self-drilling anchors solve construction difficulties

  With the rapid development of modern construction projects, the depth of foundation pits is gradually increasing and the rock layer is becoming more and more complicated, so the support becomes an essential part to ensure the safety of foundation pit projects. Many projects near the sea or near the water will encounter drifting sand layer, which has the characteristic of high fluidity and brings considerable difficulties to the support of various projects.    I. Difficulties in the construction of anchor rods in fluvial sand layer 1. Containing groundwater The sand grain size of the flowing sand layer is relatively uniform and the porosity is large, which is a kind of sandy soil layer in fluid state. It is characterized by loose structure, poor shear strength and high groundwater level. It generally appears in areas with more rivers and rich groundwater. In the foundation project, the flowing sand layer needs to pay attention to blocking sand to conduct water, and if it is not treate
