Blade coating ngu ai gaw, sumla 5-90 hta madun da ai hte maren, coatry roll (sh) web ntsa na slury coating hpe shayawm na matu, nhtu hpe lang ai ladat re. Dai ni hta, nbung n-gun-knife coating a coating n-gun hte coating n-gun gaw nbung-knife a n-gun hte nbung jet velocity hta madung nga ai, dai gaw grau nna n-gun n law ai-}viscosity- npu na hka- hpe madung tawn ai hka n-gun n-gun yawm ai lam ni a matu grau nna htuk manu ai. Organic solvent hpe madung tawn ai n-gun n-gun ni hpe lang ai shaloi, nbung law law hte wan hkru ai hka htung n-gun ni kaw na bawm kapaw ai kayau kaya ai lam ni hpe koi lu na matu sadi maja ra ai.
Coating hpe pat da ai
Curtain coat ngu ai gaw, slurry hpe slot kaw na shapraw nna, liquid curtain hku nna running web ntsa de hkrak hkrat wa ai coating ladat re. Dai gaw, shawng nnan e quantity coating ladat hta lawm ai, sumla 5{5}}91 hta madun da ai hte maren. Hpa majaw nga yang, extrusion die n-gup hte web lapran na tsan gang ai lam gaw kaba ai majaw, shingnip ntsa hta nbung n-gun n nga ai, shi gaw stringing hte scar ni zawn re ai n kaja ai lam ni hpe yeng seng kau ai hta grai kaja ai akyu ni nga ai. Dai shingnip a kinetic energy grau kaba ai majaw, meniscus hpe ngang grin hkra galaw ya ai majaw, grau tsaw ai coating speed hpe lu la mai ai. Line lawan ai lam gaw 100 m/min jan du lu nna, n-gun ja ai battery coating hparan ladat ni hta grau grau hkap la lu ai.
Wire-n htum ai rod coating
Wire-n htum ai rod coating gaw, sumla 5-92 hta madun da ai hte maren, n-gun n rawng ai web ntsa hta, n-gun rawng ai hka htung hpe langai sha zawn, shingkyit hpe lang nna, wire{1}} ai metering rod hpe lang ai. Dai wire{5}} ai n-gang hpe core rod grup yin hta n-gun ja ai stainless steel wire hte galaw da ai. Wire- ai n-gang hpe mung, coating rod (sh) tsi sarawun n-gang ngu nna mung shamying ma ai. Winding wire grai n-gun n rawng ai shaloi, coating thickness hkrak ai lam gaw micron nkau mi a kata de du lu ai. Hpa majaw nga yang, npu na-}viscosity liquid gaw hkala nba n-gun n-gun n-gun n-gun hpe loi loi hte lwi shangun ai majaw, n-gun n law ai ntsin ni hpe ka na matu htuk manu ai. Special coating rods ni hpe lang nna, coating viscosity gaw grai law ai, coating n-gun gaw 225 μm de du lu ai. Dai rod coating speed gaw 304 m/min hta sha madung tawn ai.
Coating ladat ni hpe lata ai
Coating ladat hpe lata ai gaw, myit yu ra ai lam law law nga ai hkrang masa masing langai rai nga ai. Coating ladat hpe lata ai shaloi myit yu ra ai madung lam ni gaw lawu na lam ni rai nga ai:
Coating layers ni a jahpan
Coating ladat law malawng gaw langai lang hta layer langai hpe coating galaw na matu htuk manu ai, kaga layer langai hpe gaw shawng na layer hpe hkyet kau ngut ai hpang ka-up da ai. Ladat nkau mi gaw, slide coating zawn re ai aten langai hta sha, layer law law hpe coat galaw lu ai, dai gaw, nsam film coating hta n yawm htum 9 hpe kalang ta ka-up lu ai. Curtain coating a coating baw gaw slide coating baw rai nna, coating layer mung jut kaw lwi hkrat wa ai majaw, multilayer coating hpe mung galaw mai ai. Slot-die coating hte extrusion coating gaw, single{5}}layer coating hpe galaw chye ai, raitim, lithium-ion battery galaw ai ni law law ra ai multilayer coating a matu, extrusion slot lahkawng masum hpe mung lu mai ai.
N-gun rawng ai lam
Wire-n htum ai rod coating gaw n-gun n rawng ai-layer hpe ka-up na matu htuk manu ai; extrusion coating, reverse roll coating, hte curtain coating ni gaw 400–750 μm du lu ai. General hku tsun ga nga yang, coating grau n-gun ja wa yang, coating yak hkak ai lam grau kaba wa na re. Ndai kaw tsun da ai galu kaba ai lam gaw, hka lim ai coating n-gun rawng ai lam rai nna, dry coating hte wet coating lapran na shai hkat ai lam gaw grai kaba ai hpe sadi ra ai.
Slurry n-gun rawng ai
Viscosity hte viscoelasticity gaw rheological atsam ni hpe madun dan ai hkum hkrang n-gun ni rai nga ai. Coating ladat langai hpra hta, htuk manu ai n-gun hte shear rate ni nga ai. Slurry viscosity hpe coating shear rate hta shadawn ai viscosity hte maren lata la mai ai, hpa majaw nga yang, n-gun n-gun gaw shear rate hte galai shai mat ai. Lithium battery slurry hpe woi awn ai lithium-ion ni hpe jaw ai ni jaw ai a matu, hkrak tup ai viscosity hpe hkang ai lam gaw, galaw sa wa ai lam hpe ngang grin hkra galaw na matu ahkyak ai lam langai byin wa sai. Raitim, preset quantity coating process hta, slurry hpe law malawng lang ai shear rate grai law ai majaw, ya na zawn re ai shear rate hpe lu la na matu yak hkak ai majaw, ya na zawn re ai shear rate hpe lu la na matu yak ai majaw, viscosity hpe sawn shapraw ai lam gaw grai n kaja ai, hpang jahtum e chyam dinglik ai lam a mahtai ni gaw lai mat wa na re. Viscoelasticity gaw grai ahkyak ai raitim, tau hkrau tsun na matu yak nga ai. Viscoelasticity nkau mi gaw, n-gup magap nkau mi hpe grau kaja hkra galaw ya lu ai, raitim, viscoelasticity grai law ai gaw, n-gun n rawng ai lam ni hpe n-gun n rawng hkra galaw ya lu ai.
Hkrang nsam hkrak hkrak ka da ai
Precision slot-die coating, slide coating, hte curtain coating ni gaw coating grau tsaw ai, kaga coating ladat ni a hkrak ai lam gaw fluid atsam, roller geometry, shinggrup ai lawan ai lam, hte kaga lam ni hta madung nga ai. Coating ladat shagu hta coating range kaba nga ai, dai gaw coating jak a hkrang hte bungli galaw ai ladat hta madung nga ai. Battery electrode coating arung arai ni hpe grai kaja hkra galaw ai hku nna sha, kaja ai coating mahtai ni hpe lu la mai ai.
Website masa
Web gaw non{0}}} permeable (sh) permeable rai mai ai. Permeable web a matu, pores ni hpe coating garai n galaw shi yang pat da mai ai. Web ntsa na n-gun n rawng ai hte ntsa lam n-gun hpe mung myit yu ra ai. Slurry a ntsa na tension gaw web hta grau npu de rai ra ai.
Hkrang nsam lawan ai
Coating speed gaw galaw shapraw ai atsam hte seng ai. Mai byin ai shaloi, coating speed grau lawan ai, grau kaja ai. Coating ladat yawng gaw coating speed shadawn sharam nga ai, raitim ladat nkau mi gaw high-speed coating hta grau kaja ai. Curtain coating gaw, n-gun n-gun n-htum mat hkra, n-gun n-gun n-rawng hkra, n-gup n-gu n-gun n-rawng hkra, n-gup n-gu n-gun n-rawng hkra, n-gup n-gu n-rawng hkra, n-gup n-gu n-rawng hkra, n-gup n-gu n-rawng hkra, n-gup magap n-pu n-rawng ai sha, n-gup n-gu n-rawng hkra galaw ra ai. Slide coating hta, coating layer grai n-gun n rawng ai shaloi, coating layer gaw n-gun n rawng na re. Lawan ai hte grau galu ai coating layer gaw coating n grin ai lam hpe koi lu na matu karum ya ai. Dai hte maren, n-gun ja ai hte n-gun n rawng ai web hpe grau lawan ai hku ka mai ai. Coating speed gaw katsi ai daw a galu kaba ai lam hte mung matut mahkai nga ai. Hka lim ai daw grau galu wa yang, hka lim ai lam hpe grau kaja hkra galaw na matu grau kaja ai.
