I-Sericite iyiminerali ye-silicate enesakhiwo esihle njengesikali.Inezinhlayiya ezinhle kanye ne-hydration elula.Kuncane ukushintshwa kwe-cation esakhiweni.Inani le-K+ eligcwaliswe ku-interlayer lincane kunele-muscovite, ngakho okuqukethwe kwe-potassium ekwakhiweni kwamakhemikhali kungaphansi kancane kune-muscovite.Kodwa okuqukethwe kwamanzi kuphakeme kunaleyo ye-muscovite, ngakho abanye abantu bayibiza ngokuthi i-polysilicon, i-potassium-poor, i-mica yobumba enothile ngamanzi.
Ukusetshenziswa kwe-sericite emkhakheni wezingubo
I-Superfine sericite powder iwuhlobo olusha lokugcwalisa okusebenzayo, olusetshenziswa kabanzi emkhakheni wamapende nezingubo.Ngenxa yokuthi impushana ye-sericite inomumo wesilinganiso esihle, i-crystal surface ebushelelezi, isilinganiso esikhulu sobubanzi-kuya-kugqinsi, ubumhlophe obuphezulu, izakhiwo zamakhemikhali ezizinzile, isisindo esilula, ukushelela, ukufakwa kwe-insulation kanye nokumelana nemisebe, isetshenziswa kabanzi kumapende ahlukahlukene ebanga eliphezulu, ukugqwala- ubufakazi, ubufakazi bomlilo kanye nama-anti-corrosion coatings.i-pigment filler enhle.Ngenxa yesakhiwo esinezingqimba se-sericite, ifilimu kapende ingagcinwa isikhathi eside ngaphandle kokubuna ngemva kokuba izinhlayiya zodayi zingena ezingxenyeni ze-lattice ze-sericite.
Imvelo yamakhemikhali ye-sericite ifana naleyo yezigcwalisi zokugqoka zendabuko ezifana ne-talc, i-kaolin, i-wollastonite, njll., futhi zombili zingamaminerali silicate, kodwa isakhiwo sawo esiyingqayizivele kanye nezakhiwo ezikhethekile zikwenza kuthinte izakhiwo ezifanele ze-coatings kuzicelo, isibonelo, ku Inomphumela wokuthuthukisa indiza kupende.Ukusebenzisa i-superfine sericite powder ukufaka esikhundleni sezigcwalisi zendabuko ezingaphili ekwenziweni kwe-coating kungathuthukisa kakhulu amandla efilimu enamathelayo nokunamathela phakathi kwefilimu enamathelayo ne-substrate, kuthuthukise ubuqotho, ukumelana nesimo sezulu, ukumelana ne-asidi ne-alkali kwento enamathelayo, futhi kuthuthukise ukucwenga kwefilimu. ubushelelezi befilimu yepende.Ifakwe embotsheni yangaphandle yodonga, ingathuthukisa ukumelana kwayo nokushisa, i-anti-fouling, i-anti-radiation nezinye izakhiwo.
Impushana ye-sericite egaywe ngokumanzi ingase yengezwe kopende bezinga eliphezulu ukuze kuthathelwe indawo impushana ye-zinc, impushana ye-aluminium, impushana ye-titanium, njll. Impushana ye-sericite egayiwe emanzi isetshenziswe kakhulu kupende ojwayelekile wamafutha we-linseed, ubisi lwe-butadiene, i-propylene, i-polyvinyl acetate.Ubisi olunamafutha nobisi lwe-acrylic namanye amapende odonga angaphakathi, kanye nemoto, isithuthuthu, upende wemikhumbi, njll.
Ngemva kokwengeza i-superfine sericite powder esakhiweni sensimbi esingangenwa umlilo, izakhiwo zayo ezihlobene ziba ngcono kakhulu.Ukwengeza i-sericite powder eshintshwe i-ejenti yokuhlanganisa i-titanate, umkhawulo wokumelana nokushisa we-coatingproof coating ukhuphuka ngo-25 ℃, ukumelana kwamanzi Umkhawulo ukhuphuka kusuka ku-28h kuya ku-47h, futhi amandla esibopho anyuswa kusuka ku-0.45MPa kuya ku-1.44MPa.
Ukwengeza inani elifanele le-superfine sericite powder ekuguquleni ukugqwala kungathuthukisa ukumelana nokushisa, ukumelana nesimo sezulu, ukumelana namanzi, ukumelana nokugqwala kanye nezakhiwo eziphelele zemishini yefilimu yokunameka.
Ngemuva kokwengeza i-ultra-fine sericite powder kuma-anti-corrosion coatings, ukuqina kobuso, ukuguquguquka, ukunamathela kanye nokumelana nomthelela wefilimu yokugqoka kuyathuthukiswa;Ngesikhathi esifanayo, ingakwazi ukufaka esikhundleni noma ukufaka esikhundleni se-titanium dioxide ekwakhiweni kwe-coating ukuze kuncishiswe izindleko ngaphandle kokuphazamisa ukusebenza kwe-coating.
