Adhesion Effect
Iko kunamatira kweCMC mune slurry kunokonzerwa nekuumbwa kweiyo yakasimba network chimiro kuburikidza nehydrogen bond uye van der Waals masimba pakati pemacromolecules.Kana mvura ikapinda muCMC block, mapoka e hydrophilic ane mvura shoma anokwezva anozvimba, nepo mamwe ma hydrophilic anoparadzana pakarepo mushure mekuzvimba.Iwo inhomogeneous hydrophilic mapoka muCMC kugadzirwa anokonzera kusawirirana kwakapararira particle size yemamicelles.Kuzvimba kweHydration kunoitika mukati memicelles, kuumba jira remvura rakasungwa kunze.Muchikamu chekutanga chekuparara, micelles yakasununguka mu colloid.The van der Waals force zvishoma nezvishoma inounza micelles pamwe chete, uye yakasungwa yemvura layer inoumba network network nekuda kweasymmetry yehukuru uye chimiro.Iyo fibrous CMC network chimiro ine yakakura vhoriyamu, yakasimba adhesion, uye inoderedza glaze kukanganisa.
Levitation Effect
Pasina zvinowedzera, glaze slurry inogadzikana nekuda kwesimba rinokwevera pasi nekufamba kwenguva, uye kuwedzera imwe huwandu hwevhu hakuna kukwana kudzivirira izvi kuti zvisaitike.Nekudaro, kuwedzera kweimwe chiyero cheCMC kunogona kuumba network chimiro chinotsigira kusimba kwemamorekuru e glaze.Iwo CMC mamorekuru kana ion anotambanudzira mune glaze uye anotora nzvimbo, kudzivirira kusangana kwemamorekuru e glaze uye zvimedu, izvo zvinovandudza kugadzikana kweiyo slurry.Kunyanya, iyo CMC anions inopomerwa zvisina kunaka inodzinga zvimedu zvevhu zvisina kunaka, zvichiita kuti iwedzere kumiswa kwe glaze slurry.Izvi zvinoreva kuti CMC ine kumiswa kwakanaka mune glaze slurry.Iyo network chimiro chakaumbwa neCMC zvakare inobatsira kudzikisa glaze kukanganisa uye kuve nechokwadi chekupera kwepamusoro.Pakazere, CMC inoita basa rakakosha mukugadzikana uye kumiswa kwe glaze slurry, izvo zvakakosha kuti uwane zvinowirirana uye zvemhando yepamusoro mhedzisiro mukuita kweglazing.
Mibvunzo Yekufunga Kana Uchisarudza CMC
Kushandiswa kwakakodzera kweCMC mukugadzira glaze kunogona kuvandudza zvakanyanya kunaka kwechigadzirwa chekupedzisira.Kuti uve nechokwadi chemugumisiro wakanakisisa, pane pfungwa huru dzinoverengeka dzekutevera.Chekutanga, zvakakosha kuti utarise iyo CMC modhi yakatarwa usati watenga uye sarudza yakakodzera dhizaini yekugadzira.Kana uchiwedzera CMC kune glaze panguva yekugaya, inogona kubatsira kuvandudza kushanda kwekugaya.Kutarisisa kunofanirwa kubhadharwa kune mvura-ku-CMC chiyero kana uchidira mvura kuti uwane iyo yakanyanya mhedzisiro.
Iyo glaze slurry inofanirwa kutenderwa kuora kwezuva kana maviri kuti ive nechokwadi chekuti yakagadzikana zvakakwana uye CMC inogona kutamba zvakanakisa.Izvo zvakakoshawo kugadzirisa nemazvo huwandu hweCMC yakawedzerwa zvinoenderana nemwaka shanduko, ine yakanyanya kuwedzerwa muzhizha, zvishoma muchando, uye huwandu hwe0.05% kusvika 0.1% pakati.Kana iyo dosi yakasiiwa isina kuchinjwa muchando, inogona kukonzera runny glaze, kunonoka kuoma, uye kunamira kupenya.Sezvineiwo, kusakwana dosage kunozokonzeresa kune dense uye rough glaze pamusoro.
Muzhizha, tembiricha yakakwira inogona kukanganisa viscosity yeCMC nekuda kweiyo bhakitiriya pesvedzero.Naizvozvo, zvinodikanwa kuita anti-corrosion basa uye kuwedzera akakodzera ekuwedzera kuchengetedza CMC mhando.Pakupedzisira, kana uchishandisa glaze, zvinokurudzirwa kuisefa nesefa pamusoro pe100 mesh kudzivirira zvakasara zveCMC kubva pakukanganisa glaze pamusoro panguva yekupfura.Nekutevera aya madhiraivha, CMC inogona kushandiswa nemazvo mukugadzira glaze kuvandudza chigadzirwa.
