Wanem Em Seleksen Bilong Ol Rot Bilong Kotim?

I gat planti rot bilong kotim. Dip koting i inkludim dip koting, rol koting, blade koting, na waya-………………) rot bilong kotim, na ol narapela samting. Ol rot bilong kotim kwantiti koting i gat slaid koting, slot-die koting, ekstrusen koting, na keten koting, na ol narapela samting mipela i toktok pinis long sampela rot bilong kotim long ditel antap. Daunbilo mipela i kamapim ol narapela rot bilong kotim.

Dip koting em i wanpela rot bilong kotim web i save go insait na pulimapim i go aut long slari tenk, na ekses slari i ron i go bek insait long tenk, olsem i stap long piksa 5{{1}89. Dip koting i save dabol-sait koting, olsem na pulim daireksen bilong web i save stap stret long wara pes bilong lukim olsem tiknes bilong koting long tupela sait bilong web i wankain. Planti taim, tiknes bilong kot i dipen long viskositi, densiti, spit bilong lain, na pul-aut angul. Tiknes blong slari koting long web surface i kam tik moa taem slari viskositi mo spid blong kot i go antap. I tru, dip koting i stret tu blong mekem wok blong ol kompleks wokpis we oli kompleks, be taem we solvent volatilisasen reit i spid, bae i gat flow.

Blade koting em i wanpela rot bilong kotim we i yusim wanpela blade long daunim slari koting tiknes long koting rol o web i go long spesifik tiknes, olsem i stap long piksa 5{1}}90. Namel long ol, tiknes bilong kotim na hevi bilong kot bilong ea-}nafe koting i dipen long win-}naif presa na ea jet spit, na em i gutpela moa yet long kotim low-viskositi o namel-bes’s’s slari. Taem yu yusum ol slari we oli stanap long ol ogen solvent, oli mas lukaot gud blong blokem ol samting we oli save kam antap long ol samting we oli stap bosta long ol bigfala amaon blong ea mo solvent steam we i save bon.

Curtain coating em i wanpela rot bilong kotim we ol i save rausim slari long wanpela slot na i pundaun stret long web i ran i go long fom bilong wanpela wara keten. Em i bilong preset kwantiti koting rot, olsem i stap long piksa 5{{5}91. Bikos longwe namel long ekstrusen dai lip na web i bikpela na i no gat wanpela win babol long keten, em i gat ol gutpela gutpela samting long rausim ol bagarap olsem string na ol mak. Bikos long bikpela kinetik eneji bilong keten, em i helpim long stebilisim meniskus, olsem na bikpela spit bilong kot i ken kamap. Lain spit inap kamap moa long 100 m/min na ol i wok long adoptim moa yet long ol hai-presisen bateri koting solusen.

Wire-}wun rod koting em i wanpela rot bilong kotim we i yusim wanpela waia-wun mita stik long yunifom kot wara long wanpela sof web, olsem i stap long piksa 5-92. Ol i save wokim rop bilong waia{5}}}wun long rot bilong strongpela steinles stiel waia i gat strongpela win na i gat strongpela win long wanpela as stik. Ol i kolim tu stik bilong waya{8}}}. Taem waea we i tantanem i smol tumas, tiknes blong tiknes ia i save kasem insaed long sam maekron. Bikos low-viskositi wara i save ron isi isi long sua metal waya, em i gutpela long karamapim ol wara i no gat bikpela viskositi. Iusum ol spesel rop blong koting, viskositi blong koting i save hae lelebet, mo tiknes blong koting i save kasem 225 μm. Rod koting i save stap long 304 m/min.

Seleksen bilong rot bilong kot em i wanpela sistemik projek wantaim planti samting yu mas tingim. Ol dispela em ol bikpela samting ol i mas tingim taim ol i makim rot bilong kotim:

Planti rot bilong kotim i gutpela long kotim wanpela leit long wanpela taim, na narapela leit i save kot bihain long ol i draim pinis leit bipo. Sampela rot inap karamapim planti leit long wankain taim, olsem slaid koting, we inap kotim 9-pela leit long wankain taim long kala film koting. Het bilong keten koting em het bilong 'slide coarting' het, na 'coating layer' tu i save ron i go daun long arere, olsem na ol i ken mekim wok bilong kotim planti leit tu. Slot-die koting na ekstrusen koting i save mekim singel-lei koting, tasol ol i ken gat tupela o tripela ekstrusen slot tu bilong multileia koting we planti manmeri i laikim long litiam-on bateri manifakta.

Waya-}wal stik koting i gutpela long tin-lei koting; ekstrusen koting, rives rol koting, na keten koting i gutpela long tikpela koting, we inap kamap long 400–750 μm. Long tok ples, taim kot i liklik moa, hevi bilong kot i bikpela moa. I gud blong makem se tiknes we oli tokbaot long ples ia i wetwet tiknes, mo difrens bitwin drae koting mo wet koting i bigwan tumas.

Viskositi na viskoelastisiti em ol mak bilong bodi we i soim ol samting bilong rheological. Wanwan rot bilong kotim i gat sampela kain gutpela viskositi na shear reit. Slurry viskositi i bes blong jusum folem viskositi we oli mesarem long koting shear rate, from se viskositi i jenis wetem shear rate. Long litiam bateri slari fomulasen we ol lida litiam-on bateri materiel saplaia i givim, stretpela viskositi kontrol i kamap wanpela bikpela samting long proses stebiliti. Tasol, long preset kwantiti koting proses, shear reit we slari i save stap aninit long en i antap tumas, olsem na em i hat long winim dispela kain hai shear reit wantaim ol instramen bilong nau, olsem na viskositi estimesen i raf, na las tru ol eksperimen risal bai win. Nating se viskoelastisiti i impoten tumas, i had blong talem. Sampela viskoelastisiti i helpim long kamapim gutpela wok bilong sampela koting, tasol bikpela viskoelastisiti inap mekim na ol i no inap pulim ol samting i no stret.

Presisen slot-die koting, slaid koting, na keten koting i gat bikpela mak bilong koting, taim stretpela bilong ol narapela rot bilong kotim i dipen long ol samting bilong wara, rola jiometri, rotesen spit, na ol narapela samting. Olgeta rot bilong kot i gat bikpela mak bilong kot, we i dipen long straksa na operesen mod bilong divais bilong kotim. Tasol sapos yu mekim gutpela wok tru long stretim ol samting bilong kotim ol bateri elektrod, ol inap kisim ol gutpela samting bilong kotim yu.

Web i save no blong'0}}}long taem o i save go insaed. Long web we i save go insaed, ol pores oli save silim bifo oli kotem. I nid tu blong tingbaot raf fasin mo tensen we i stap antap long web. Pesen bilong slari i stap antap i mas i stap daunbilo long dispela bilong web.

Spid blong kot i rileit long prodaksen efisiens. Taem i posibol, moa spid blong kot i spid, i moa gud. Olgeta rot bilong kot i gat mak bilong spit, tasol sampela rot i gutpela moa long hai-speed koting. Curtain coating i nidim minimam flow rate blong mekem sua se keten i no tearem, so hae-}speed koting i no save kamaot taem leja i smol. Long slaid koting, taim leit bilong kot i liklik tru, leit bilong kot bai i no stap gut. Hae spid mo tik moa koting leja i help blong blokem fasin blong no stap strong long kot. Sem mak, web we i smut mo i no blong -}wan we i save stap oltaem, yu save kavremap long spid we i hae moa. Spid blong koting i rileit tu long longfala blong seksen blong draem. Longpela hap bilong draim, em i gutpela moa long apim mak bilong drai.

Ol rot bilong kot na ol mak bilong ol i stap long Tebol 5-6.

Ol rot bilong kotim ol litiam-on bateri elektrod pepa em ol rol koting na ekstrusen koting pastaim. Rives rol koting i nidim bikpela shear reit, i gutpela long slari wantaim viskositi i antap liklik, kisim tikpela koting film na gutpela koting kwaliti, na nau em i nambawan rot ol i save yusim moa long koting rot bilong litiam-on bateri. Ekstrusen koting i makim wanpela teknoloji i kamap gutpela tru long indastri. Wanpela presa i save kamap long slari long taim bilong koting, we ol i ken yusim long kotim bikpela viskositi slari.
