Electronic device cooling, energy battery thar, aerospace leh field dang dangah te hman a ni nasa hle. Production process-ah hian precision step tam tak a awm a, chung zingah chuan raw material pretreatment, graphitization, calendering, leh post-processing te pawh a tel.
Raw Material Pretreatment .
Graphite paper hi a tlangpuiin natural flake graphite emaw synthetic graphite atanga siam a ni. A hmasain, raw material chu pulverization leh classification a tawk a, bulk graphite chu micron-sized fine powder-ah grinding a ni a, chu chuan a hnua processing step-ah uniformity a ti tha zawk a ni. Chumi hnuah chuan graphite thianghlimna 99% aia tam a nih theih nan silicate leh iron oxide te ang chi bawlhhlawh te chu flotation emaw chemical purification hmangin an paih chhuak thin. Graphite paper thianghlimna sang tak mamawhna atan chuan high-temperature acid washing emaw alkali fusion emaw hmangin tihthianghlim belh a ni.
Graphitization 1000 a ni.
Graphite powder pretreated hian a layered structure tihsan nan temperature sang takah graphitization a paltlang a. Hetiang kalphung hi a tlangpuiin graphitization furnace-ah (Acheson emaw induction furnace ang chi) 2800℃aia sangah a thleng a, amorphous carbon chu graphite structure crystalline sang takah a chantir thin. Graphitization hian material thermal leh electrical conductivity a ti tha mai bakah a mechanical strength a tichak bawk. Process thenkhatah chuan a hnu lama rolling performance tihchangtlun nan binder (phenolic resin emaw pitch ang chi) dah belh a ni a, mahse, residual impurities awm lohna turin temperature sang takah carbonization kimchang a ngai a ni.
Calendaring 1000 a ni.
Graphitized material chu crush leh screened a ni a, chutah chuan lubricant tlemte (molybdenum disulfide ang chi) nen an pawlh a, multi-stage calender hmangin an roll chhunzawm zel a ni. A tir lamah chuan roughing rolls hmangin a thickness a tlahniam a, chu chu target thickness (typically 0.05-2mm) thlengin zawi zawiin refinement a ni leh a. Calendering process chhung hian graphite layer leh smooth surface inkara tight bonding neih theih nan temperature (100-300℃vel) leh pressure te chu khauh taka control a ngai a ni. High-end graphite paper thenkhatah pawh density leh dimensional stability tihchangtlun belh turin cold rolling an tawk bawk.
Post-processing leh quality enfiahna .
A lo pian hnuah chuan graphite paper chu a tul angin a cut a, a trim a, a surface treatment (anti-oxidation coating ang chi) a nei bawk. A tawp berah chuan quality testing khauh tak a nei a, chu chu thickness tolerance, thermal conductivity (1500-2000 w/m·k thleng), tensile strength, leh purity analysis te a ni a, chu chuan product chu industry standard a tlin theih nan a pui a ni.
Graphite paper siam dan tur hian materials science leh precision manufacturing technology te a inzawm khawm a ni. Process optimize hian final performance a nghawng nghal a, chu chuan tunlai high-end manufacturing atana foundational material pawimawh tak a siam a ni.
