{"product_id":"essdbehrpars","title":"ECS-SS Hot Rolling Press (W=100mm, 120℃) with Asynchronous Rolling Speed for Dry Battery Electrode (DBE), ESSDBEHRPARS","description":"\u003cp\u003eIn the fabrication of dry battery electrodes—where active materials, conductive agents, and PTFE binders are \"fibrillated\" without the use of NMP solvent—the Asynchronous Rolling Speed (ARS) press is a sophisticated tool. Unlike standard calendering where both rollers spin at the exact same velocity, ARS introduces a controlled speed differential between the top and bottom rollers. This creates mechanical shear at the nip, which is the secret to high-performance dry-film electrodes.\u003c\/p\u003e\n\u003cp\u003eDry electrode technology relies on the fibrillation of PTFE. When you apply both compression and shear, the PTFE particles stretch into a microscopic \"spider-web\" matrix that holds the active material together. (1)\u003cstrong\u003e Shear-Induced Fibrillation\u003c\/strong\u003e: By spinning one roller faster than the other (e.g., a ratio of 1.1:1 or 1.2:1), the material is \"smeared\" slightly as it is crushed. This maximizes the fibrillation of the binder, creating a stronger, more flexible dry film. (2) \u003cstrong\u003eSurface Smoothing\u003c\/strong\u003e: ARS can help eliminate \"orange peel\" textures on the surface of the dry electrode, leading to more uniform contact with the current collector. (3) \u003cstrong\u003eOrientation Control\u003c\/strong\u003e: The speed differential helps orient the polymer chains in the direction of the rolling, which can improve the mechanical tensile strength of the free-standing dry film.\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\u003eESSDBEHRPARS (ESS-DBE-HRPARS)\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, 1000 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\u003eHot Roller\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003eΦ95×115mm mm (effective hot rolling width: 100 mm)\u003c\/li\u003e\n\u003cli\u003eRoller is made of alloy stainless steel and surface plated with Cr layer\u003c\/li\u003e\n\u003cli\u003eSurface Hardness: HRC60～62, surface coating thickness: ≥10mm, Ra=0.4\u003c\/li\u003e\n\u003cli\u003eHeating temperature: Max:120℃ (independently controlled)\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\u003e0.05- 1 m\/min (step motor)\u003c\/li\u003e\n\u003cli\u003eTwo rolling speeds of upper and bottom rollers is independently controlled.\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\/Pressure\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0-0.5 mm, digital adjustable (0.001mm)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTwo pressurized modes: \u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e           For small pressure (20-80 kg), adjustable\u003c\/p\u003e\n\u003cp\u003e           For large pressure, gap-controlled, not adjustable (Max. 2T)\u003c\/p\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\u003cp\u003e \u003cstrong\u003eDry electrode fabrication processes: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli style=\"font-weight: bold;\"\u003e\u003cstrong\u003e(1) Powder Mixing\u003c\/strong\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe active material (eg: graphite, LFP, NMC) is mixed with conductive carbon at medium level speed, and then add the PTFE into the mixture and mix it at a low speed (Temperature=10-15℃).
