{"product_id":"ersecgccrp","title":"ECS-RS Gap-Control Cold Rolling Press (W=100-250mm) for Electrode Calendering, ERSECGCCRP","description":"\u003cp\u003eIn battery electrode fabrication and advanced membrane manufacturing, a Gap-Control Cold Rolling Press (also known as a fixed-gap calender) is a high-precision instrument designed to control the physical thickness of a processed sheet.\u003c\/p\u003e\n\u003cp\u003eA gap-control system establishes a completely rigid mechanical boundary condition. (1) \u003cstrong\u003eThe Displacement Lock\u003c\/strong\u003e: The distance between the rollers is adjusted via micro-threaded screws or fine wedges, typically featuring a resolution down to ±1um (or 0.001 mm). Once set, the vertical position of the roll bearings is mechanically locked. (2) \u003cstrong\u003eVariable Reaction Forces\u003c\/strong\u003e: As a dried electrode sheet or composite polymer membrane (like a Zirfon-type diaphragm or a dry-film PTFE matrix) passes through the nip, the machine applies whatever force is necessary to crush the material down to that precise gap width. If the incoming sheet has local thick spots or a high areal density, the local separating force spike can be massive.\u003c\/p\u003e\n\u003cp\u003eWhen evaluating a benchtop or pilot-scale gap-control cold press, look for these key structural features: (1) \u003cstrong\u003eRoller Hardness\u003c\/strong\u003e (≥ 60-65 HRC): The rollers must be machined from hardened tool steel (often chrome-plated or tungsten carbide coated). If the rollers are too soft, hard active ceramic particles can pit the mirror finish (Ra \u0026lt; 0.2um), leaving permanent defects on subsequent runs. (2) \u003cstrong\u003eDial\/Digital Micrometer Precision\u003c\/strong\u003e: High-end laboratory units feature independent dual digital micrometers. This allows researchers to deliberately introduce a micro-taper or perfectly balance the alignment to eliminate asymmetric \"bannaning\" or wrinkling of the metal current collector foil. (3) \u003cstrong\u003eGlovebox Adaptability\u003c\/strong\u003e: For processing moisture-sensitive materials—like solid-state sulfide electrolytes or sodium-ion battery polyanionic cathodes—ensure the motor housing, electrical lines, and adjustment knobs are compatible with a sealed Argon-filled glovebox environment.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"height: 580px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eERSECGCCRP (ERS-EC-GCCRP)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003ePower\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eAC110-220V±10%, single phase, 50\/60Hz, 200 W \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 106.4px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 106.4px;\"\u003e\u003cem\u003eRolling Roller\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 106.4px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eΦ96 x 100-250 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\u003cli\u003eSurface Flatness: 0.4 um\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eCalendering Speed\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\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 style=\"height: 47.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 47.6px;\"\u003e\u003cem\u003eCalendering Gap\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 47.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003e0-2.0 mm, manually adjust\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 81.6px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 81.6px;\"\u003e\u003cem\u003eRoll-to-Roll Integration (\u003cspan style=\"color: rgb(255, 42, 0);\"\u003eOptional\u003c\/span\u003e)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 81.6px;\"\u003e\n\u003cul\u003e\n\u003cli\u003eA roll-to-roll unit can be integrated with the cold rolling press for electrode roll calendering\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e          \u003cimg style=\"float: none;\" alt=\"\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/ERSECGCHRP_02_01_100x100.png?v=1782234277\"\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 106.4px;\"\u003e\n\u003ctd style=\"width: 17.9856%; height: 106.4px;\"\u003e\u003cem\u003eNote\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 81.6547%; height: 106.4px;\"\u003e\n\u003cdiv style=\"text-align: left;\"\u003e\n\u003cul\u003e\n\u003cli\u003eEach time the reduced thickness is 20%-25%.
