Chekutanga, musimboti wekusanganisa
Nekukurunga mapanga nefuremu inotenderera kuti itenderedzane, kusimudzirwa kwemuchina kunogadzirwa uye kunochengetwa, uye kutamiswa kwehuwandu pakati pezvikamu zvemvura neyakasimba kunowedzerwa. Kukurunga kwemvura yakasimba kunowanzo kamurwa kuita zvikamu zvinotevera: (1) kusungirirwa kwezvikamu zvakasimba; (2) kusimudzirwa kwezvikamu zvakagadzikana; (3) kupinda kwezvikamu zvakasungirirwa mumvura; (4) kushandiswa pakati pezvikamu uye pakati pezvikamu nemapaddles Simba rinoita kuti zvikamu zvezvikamu zvipararire kana kudzora saizi yezvikamu; (5) kutamiswa kwehuwandu pakati pemvura neyakasimba.
Chechipiri, mhedzisiro inomutsa
Maitiro ekubatanidza zvinhu zvakasiyana-siyana zviri mu slurry anosanganisa zvinhu zvakasiyana-siyana zviri mu slurry pamwe chete muchiyero chakajairika kuti agadzire slurry kuti zvive nyore kufukidza zvakafanana uye kuve nechokwadi chekuti zvidimbu zvematanda zvinogara zvakanaka. Zvinhu izvi zvinowanzova nemaitiro mashanu, anoti: kugadzirira, kusanganisa, kunyorovesa, kupararira uye kupwanya zvinhu zvakagadziriswa.
Chechitatu, maparamita ekutsvedza
1, kusimba:
Kuramba kwemvura kuyerera kunotsanangurwa sehuwandu hwekumanikidzwa kwekucheka hunodiwa pa 25 px 2 plane kana mvura yacho ichiyerera nechiyero che25 px/s, chinonzi kinematic viscosity, muPa.s.
Kusviba kwemvura (viscosity) imhando yemvura. Kana mvura ichiyerera mupombi, pane mamiriro matatu ekuyerera kwemvura (laminar flow), kuyerera kwekuchinja kwemvura (transitional flow), uye kuyerera kwemvura (turbulent flow). Aya mamiriro matatu ekuyerera kwemvura aripowo mumidziyo yekukurunga, uye chimwe chezvinhu zvikuru zvinosarudza mamiriro aya ndiko kusviba kwemvura.
Munguva yekukurunga, zvinowanzoonekwa kuti viscosity iri pasi pe5 Pa.s mvura ine viscosity yakaderera, senge: mvura, mafuta e castor, shuga, jamu, huchi, mafuta ekuzora, emulsion ine viscosity yakaderera, nezvimwewo; 5-50 Pas mvura ine viscosity iri pakati nepakati Semuenzaniso: inki, mushonga wemazino, nezvimwewo; 50-500 Pas mvura ine viscosity yakawanda, senge chewing gum, plastisol, solid fuel, nezvimwewo; anopfuura 500 Pas mvura ine viscosity yakawanda senge: musanganiswa werabha, plastic melts, organic Silicon nezvimwewo.

Hukuru hwehukuru hwezvikamu zve50% nehukuru hwezvikamu zviri muslurry
3, zviri mukati zvakasimba:
Chikamu chechinhu chakasimba chiri mumatope, chiyero chedzidziso chezvakasimba chiri pasi pezvakasimba zviri mukutumira.
Chechina, chiyero chemigumisiro yakasanganiswa
Nzira yekuona kufanana kwekusanganisa nekusanganisa sisitimu yekumisikidza yakasimba-mvura:
1, kuyerwa kwakananga
1) Nzira yekusviba: kutora sampuro kubva munzvimbo dzakasiyana dzesystem, kuyera viscosity yeslurry uchishandisa viscometer; kana kutsauka kudiki, kusanganisa kwacho kwakafanana;
2) Nzira yezvikamu:
A, kutora sampuro kubva munzvimbo dzakasiyana dzesystem, uchishandisa chikwenya chehukuru hwezvimedu kuti uone hukuru hwezvimedu zveslurry; kana hukuru hwezvimedu huri pedyo nehukuru hweupfu hwezvinhu zvakabikwa, kusanganisa kwakafanana;
B, kutora sampuli kubva munzvimbo dzakasiyana dzesystem, uchishandisa laser diffraction particle size tester kuti uone saizi yeparticle yeslurry; kana kugoverwa kweparticle size kwakajairika, zvidimbu zvikuru zvidiki, kusanganiswa kwacho kwakafanana;
3) Nzira chaiyo yekukwevera pasi: kutora sampuro kubva munzvimbo dzakasiyana dzesystem, kuyera huwandu hweslurry, kutsauka kudiki, kusanganisa kwakafanana.
2. Kuyera zvisina kunanga
1) Nzira yekubvisa zvinhu zvakaoma (macroscopic): Kutora sampuro kubva munzvimbo dzakasiyana dzesystem, mushure mekupisa kwakakodzera uye nguva yekubika, kuyera huremu hwechikamu chakasimba, kutsauka kudiki, kusanganisa kwakafanana;
2) SEM/EPMA (microscopic): sampuli kubva munzvimbo dzakasiyana dzesystem, isa pasita, omesa, uye tarisa zvidimbu kana zvinhu zviri mufirimu mushure mekuomesa slurry neSEM (electron microscope) / EPMA (electron probe) Kugoverwa; (zvigadziko zvesystem zvinowanzova zvinhu zvinokonzeresa)

Maitiro ekugadzira nekuputira cathode:
7. Hunhu hwekusviba kwetsvina
1. Kukombama kwe slurry viscosity nenguva yekukurunga
Sezvo nguva yekukurunga ichiwedzerwa, viscosity yeslurry inowanzova kukosha kwakasimba pasina kuchinja (zvinogona kutaurwa kuti slurry yakapararira zvakaenzana).
2. Kukombama kwe slurry viscosity nekupisa
Kana tembiricha yakakwira, viscosity yeslurry yakaderera, uye viscosity yacho inova yakasimba kana yasvika patembiricha yakati.
3. Kukombama kwehuwandu hwakasimba hwetangi rekutamisa mvura nekufamba kwenguva
Mushure mekunge slurry yakurungwa, inoiswa papombi kutangi rekutamisa kuti ifukidzwe neCoater. Tangi rekutamisa rinokurungwa kuti ritenderere: 25Hz (740RPM), revolution: 35Hz (35RPM) kuona kuti parameters dzeslurry dzakagadzikana uye hadzizochinje, kusanganisira pulp. Tembiricha yezvinhu, viscosity uye solid content kuona kuti slurry coating yakafanana.
4, viscosity ye slurry ine nguva yakakombama
