{"product_id":"etmecgchrp","title":"ECS-TM Gap-Control Hot Rolling Press (W200mm, 130°C) for Electrode Calendering, ETMECGCHRP","description":"\u003cp\u003eFor high-precision electrode calendering, transitioning from simple gap-control (setting the distance between rollers) to pressure-control is the key to achieving consistent energy density and ionic conductivity. In a pressure-controlled system, the machine uses hydraulic or servo-actuators to apply a specific, measurable force (typically in metric tons) regardless of slight variations in the initial coating thickness.\u003c\/p\u003e\n\u003cp\u003eWhen using a pressure-control press, your goal is to optimize the Packing Density (PD) = m\/(A*t). Where m is the mass of active material, A is the area, and t is the post-calendering thickness. (1) \u003cstrong\u003e10% Rule\u003c\/strong\u003e: For most lithium-ion cathodes (NMC\/LFP), aim for a thickness reduction of approximately 10–20% per pass. Attempting more can cause \"spring-back\" or delamination. (2) \u003cstrong\u003eThermal Softening\u003c\/strong\u003e: Calendering at 60-100 °C reduces the yield strength of the PVDF binder, allowing for higher density at lower pressures and reducing the risk of foil cracking. (3) \u003cstrong\u003eLinear Pressure\u003c\/strong\u003e: In production, pressure is often reported as N\/mm (force divided by the width of the electrode). Lab machines that report total \"Tons\" should be converted to linear pressure for academic reporting.\u003c\/p\u003e\n\u003ctable style=\"height: 201.2px;\" width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 35.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 35.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 35.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eETMECGCHRP (ETM-EC-GCHRP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC220V±10%, single phase, 50\/60Hz, 2000 W \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCold Roller\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eΦ96 x 200 mm (effective width for hot rolling: 180 mm)\u003c\/li\u003e\n\u003cli\u003eRoller is made of Cr12Mo1V1 and surface plated with Cr layer\u003c\/li\u003e\n\u003cli\u003eSurface Hardness: HRC62, surface coating thickness: ≥10mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003ePressure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMax. 2-3T (gap-control, pressure cannot be adjusted)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eRolling Temperature\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eMax. 130 \u003cspan\u003e°C\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Speed\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0-40 mm\/s, digital display, adjustable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eCalendering Gap\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0-3.0 mm, manually adjustable \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 17.9856%;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEach time the reduced thickness is 20%-25%.
