PVDF Zhejiang Fu Norlin chemicals | Qingyuan PVDF | East Exhibition plastic

Shanghai 3F PVDF can be molded, injection, extrusion, coating methods such as forming. 1. Preheat the first molded PVDF powder filling people die in 165 ℃, at 190 ~ 205 ℃ and 14MPa compression molding, dwell time is about 5min, then the mold is cooled to about 90 ℃, you can remove the finished product . Touch with molded should use hard chrome steel or high nickel stainless steel. 2, injection molding material injection molding Jane temperature should be controlled within a range of 230 ~ 280 ℃, mold temperature 80 ~ 140 ℃, complex shape and thickness of 5 mm less than the thin-walled products, chess temperature may also be raised. An injection pressure of 100? 150MPa, the molding cycle 40 ~ 60s. Shanghai Sanai molding shrinkage rich PVDF products is very low, typically only 0.03%. 3, can be an ordinary extruder, extrusion molding PVDF, choose an aspect ratio of 16 to 20, and a compression ratio of 2, and so on pitch screw. Screw and barrel should be used special heat resistant corrosion resistant alloy, chrome-plated stainless steel mold material available. Extrusion barrel temperature control in 220? 260 ℃ PVDF Zhejiang Fu Norlin chemicals, die temperature of 230- 275 ℃. It can be extruded plate, bar, tube, film and other products. Products for the thin-walled products can be cooled with water, 6 mm or more thick-walled products, it should be placed in the oven to cool slowly. 4, salivation salivation cast molding cast molding is mainly used to produce films. In dimethylacetamide, PVDF Shanghai 3F formulated into a plate of 20% solids solution was cast on aluminum foil, the 204? After 316 ℃ melt, quenched with water can be obtained 0.051 ~ 0.076 mm thick, strong Toughness film. With a solid content of 45% dispersion flow cast molding, film strength and toughness can be obtained by 0.10-0.15 mm thick. Also PVDF Zhejiang Juhua, this dispersion can be spray forming. The current development status of domestic and global PVDF PVDF main production enterprises Arkema chemical company, Solvay, Belgium, the United States 3M, American Osment company and Atofina, Japan Kureha and Daikin, 2005 production capacity of about 43,000 tons, the output of about 33,000 tons, of which France Alto chemical production capacity will reach 12,000 tons / year. The current global PVDF in the petrochemical field and steady growth in demand for architectural coatings, and flexible tubing regard for lithium batteries and semiconductor industry will rapidly increase, annual demand growth rate of over 20%.
