Wood plastic composite template material mixing from PVC and waste recycling materials and wood fibers and plant fibers, add help to help Double screw extrusion machine, high temperature heatingSqueeze out and suppress the molding to make plates. Adopting extruded molding process methods, it focuses on ensuring that wood powder and fillers are filled with high filling system with high liquidity and permeability, prompting plastic melts to fully bond the wood powder and fillers to achieve common compounding Mechanical performance and other aspects of use performance eventually produce higher -performance templates at a lower cost. The inward foaming or CELUKA, that is, the foaming method. The products produced by this process method are hard, smooth, and have good mechanical performance. Main raw materials: PVCSG-5, SG-7; fiber: wood powder, plant fiber, straw powder, plant shell, etc. Generally speaking The larger the diameter, the lower the water content, the lower the better (not less than 0.3%); the additive: coupling agent, lubricant, light stabilizer, antibacterial agent, water absorption, etc.
Select the average polymerization PVC polymerization P \u003d 1000, the modified auxiliary SG-5, and the aggregation is increased to 1300 (about 70 K value), which can supplement the insufficient viscosity; consider recycling the brittleness of the plastic The content is 35%\u0026#8764; 40%), and the dosage is 1/3 of the CACO3, so that
Non Woven Spundbond Machine
will reduce the concentration of the filler and control the amount of the two in the reasonable amount. The main performance returns to the performance of the state of the new product. Puppet nitrogen di metamimam (AC) foam, ZNO pigment, plasticizer: DBP, \u0026 nbsp; DOP, stabilizer: zinc acid zinc, calcium calcium, coupling agent: KH-550 (KH-550 ) Compatible agent: methyl methampite (MMA) and acrylic (BA). Antioxidants: peroxidine-2-ethyl nicotyl (TBPEH), flame retardants: SB2O3; fillers: calcium carbonate, wood powder, other additives, etc.
Main production equipment: ① The same direction of dual screw extrusion machine. Model SJ-150, screw speed: nmax \u003d 14-22R/min, host current: 50 \u0026#8764; 80A, screw speed: 12r/min; extrusion: 204g/min; long diameter ratio (L/d) is the long diameter ratio (L/d) is the long diameter ratio (L/d) is the long diameter ratio (L/d) is the long diameter ratio (L/d) is the long diameter (L/d) is the aspect 30: 1; Schedule speed adjustment: plasticization ability: 90kg/h or more; motor power: 45kW. ② High -speed mixed machine, temperature of 90 ° C, speed 1000r/min. \u0026 nbsp; ③ grinding machine, pinching machine, traction machine, cutting machine. ④ Electronic balance.
Process parameter control: (1) Process temperature: The temperature is divided into five segments, the fuselage: the supply section is 175-186 ° C, the compressed section is 180-186 ° C, the measurement section is 185-190 ° C; 190-200 ° C, connector: 175-185 ° C. (2) Squeeze speed: When the speed is 12R/min, it can get better mixed quality and surface quality, and squeeze out smoothly, smooth product, dense internal structure, and good strength.(3) Traction speed: The traction speed must be matched with the extrusion speed. Under normal production, the traction speed should be 3-5%faster than the extrusion speed. The speed of the host screw is 15-20r/min.(4) Other controls such as head pressure, mold temperature and other controls. On February 1, 2014, JG/T418- 2013 \”Plastic Template\” industry standards were officially implemented, promoting the healthy development of the plastic membrane industry.The new PVC wooden plastic template can be reused. It is environmentally friendly, easy to maintain, and easy to build, and can be recycled and regenerated. It can reduce the damage of plastic to the environment.\u0026 nbsp;
