Rubber, the more flexible it is, the better its toughness. It burns very well and can continue to burn after leaving the fire. The upper end of the flame is yellow and the lower end is blue. It will melt when burning, with liquid dripping and no black smoke coming out. At the same time, it emits the smell of acetic acid when burning
Advantages: Acid-resistant, not resistant to organic solvents, soluble in aromatic hydrocarbons and hydrocarbons, excellent electrical insulation, resistant to low temperatures, and maintains great toughness. Resistant to odor, fumigation and mold. When the content is low, it is soft and has good impact strength. When the content is high, it has rubber-like elasticity and greater transparency. Generally speaking, it feels good, has rubber elasticity, is low and soft, is resistant to folding, bending, stress cracking, and can withstand large load impacts.
Disadvantages: Easy to stick to the mold, susceptible to thermal decomposition, and poor thermal performance. The surface hardness is low and easy to scratch. Easy to print, printing performance is superior.
Used for extruded packaging films, agricultural films, stretch films, soft water pipes
Used for injection molded rubber elastic accessories, such as sealing rings, shock absorbers, disposable bottle caps, etc.
Used for Low-temperature modifier for other materials
The melting point of injection molding is ℃, and the decomposition temperature is ℃. When injection molding, the general use temperature is ℃. Because it is an olefin plastic, it does not absorb water, and does not need to be dried during production. However, for the sake of product quality, it can be dried at ℃ to discharge floating water. It has poor thermal stability and is easier to decompose. Therefore, when injection molding, do not stay in the screw for too long. When decomposing, a large amount of acetic acid smell will be released. It has static electricity and the surface easily attracts dust. The shrinkage rate and overflow value are...
1. Automotive interior sheet extruder production line process flow
Pressurized internal mixer & automatic stainless steel elevator & cone double forced feeder single screw extruder forming die three-roller calender Traction machine, cutting machine and conveyor
2. Unit characteristics
This unit is designed for sheet materials. Compared with the traditional production process, it reduces the number of starts and is truly low-input, low-noise, and low-energy. The screw is designed with special mixing function and high plasticizing capacity based on the concept of consumption, high efficiency, high return, less labor, stable quality and continuous production. The hanger-type die adopts a special double-throttle design to make the thickness adjustment of the sheet more accurate. Temperature control ℃ can well control the plasticizing process and the thickness and flatness of the sheet. The three-roller calender adopts horizontal, vertical or tilted type and can be lifted and lowered freely. The plate thickness control uses screw adjustment and two-way adjustment of the pressure wheel to control the plate thickness. The independently controlled roller temperature control system can well control the temperature of the pressing roller to ensure uniform thickness of the sheet. Slicing machine, plate length and quantity are accurate. Equipped with automatic meter counter to set product length.
3. Wide scope of application
This production line can produce shoe materials or other boards and sheets. The equipment has strong adaptability to the amount of calcium carbonate added (up to).
It can process, etc. at the same time.
Application fields: car ceilings, car trunk pads, car floor mats, etc.
The sheet machine is suitable for twin-screw extruders
The twin-screw extruder is equipped with a volumetric feeder lubrication system inside and outside Cooling circulation system, vacuum system, screen changing system, heating system, main control system, power system, auxiliary system
