The conical twin-screw extruder is the main equipment for producing plastic profiles. When the profile is produced, the twin screw rotates outward in the barrel in different directions. The size of the screw gap not only affects the plasticizing effect of the material, but also affects the quality of the product, sometimes causing machine failure, and even leading to scrapping of heart parts such
Conical twin screw extruder The conical twin screw extruder is an efficient mixing and extrusion equipment. The machine has the characteristics of small shear rate, difficult decomposition of materials, uniform plasticization and mixing, stable quality, high output, wide application range and long service life. Chinese name conical twin-screw extruder is used to modify various plastics with stab
What are the types of polymer waterproof membrane 1. PE waterproof membrane: this kind of waterproof membrane has good insulation, mainly used in pools, river embankments, garbage dumps; 2. ECB waterproof membrane: ECB waterproof membrane is used in a wide range and has good toughness 1. Electrical insulation; 3. PVC waterproof coiled material: This is a non-crystalline substance with high stre
It is made of high polymer and some materials or polymer materials as the base material with additives and fillers. It is used in outdoor building walls or roofs and other places that need to be shielded from rain. It is a flexible building product that can be rolled. In the building Water engineering plays an important role in practice. It is widely used in the waterproofing of buildings above g
There are several waterproof membranes There are three main types of waterproof membranes, namely asphalt waterproof membranes, polymer modified asphalt waterproof membranes and synthetic polymer waterproof membranes. Each type of waterproof membrane is also classified into many categories, for example, asphalt waterproof membranes are divided into Tire roll material and tireless roll material,
Development and prospects of waterproof materials When it comes to the development prospects of the waterproof industry, one has to mention a derivative product in recent years-plugging agent, plugging mortar. Waterproofing and water leakage are relative. Most houses in the past did not pay much attention to waterproofing or just did some surface work that had their surface, so now a series o
my country's waterproof membrane market share has a good prospect of improvement Waterproof coiled material is mainly used in building walls, roofs, tunnels, highways, etc. This is a curlable flexible building material product that can resist external rainwater and underground seepage. With the improvement of various technologies in my country, the product quality of some enterprises has ap
Waterproof prospects and market analysis 1. Market prospects 1. Understanding of building waterproofing Building waterproofing is a measure taken from building materials and structures to prevent water from penetrating certain parts of the building. According to the different measures taken, the main application areas include roofing, basement, exterior walls and interiors of house cons
