Sericite

Sericite ni minerval silicike ifite igipimo cyiza-gisa nuburyo.Ifite ibice byiza kandi byoroshye.Hano haribintu bike byasimbuwe muburyo.Ingano ya K + yuzuye muri interlayer ntabwo iri munsi ya muscovite, bityo potasiyumu yibigize imiti iri munsi gato ugereranije na muscovite.Ariko amazi arimo arenze ayo muscovite, kuburyo abantu bamwe babyita polysilicon, potasiyumu-ikennye, mika ikungahaye kubumba.

Gukoresha sericite murwego rwo gutwikira

Ifu ya superfine sericite ni ubwoko bushya bwuzuza imikorere, bukoreshwa cyane mubijyanye no gusiga amarangi.Kuberako ifu ya sericite ifite ubunini bwiza, hejuru ya kirisiti yoroheje, igipimo kinini cya diametre-yubugari, umweru mwinshi, imiterere ihamye ya chimique, uburemere bworoshye, ubworoherane, insulasiyo hamwe n’imishwarara y’imirasire, ikoreshwa cyane mu marangi atandukanye yo mu rwego rwo hejuru, ingese- gihamya, irinda umuriro hamwe na anti-ruswa.kuzuza pigment nziza.Bitewe nuburyo bwa serisite, firime yo gusiga irangi irashobora kubikwa igihe kirekire idacogora nyuma yuko ibice by'irangi byinjiye mubice bya sericite.

Imiterere yimiti ya sericite isa niy'ibisanzwe byuzuzanya nka talc, kaolin, wollastonite, nibindi, kandi byombi ni amabuye y'agaciro ya silikate, ariko imiterere yihariye n'imiterere yihariye bituma bigira ingaruka kumiterere yimyenda ikoreshwa mubisabwa, kuko urugero, muri Ifite ingaruka zo kongera indege mumarangi.Gukoresha ifu ya sericite ya superfine kugirango isimbuze ibisanzwe byuzuza ibinyabuzima muburyo bwo gutwikira ibintu bishobora kongera imbaraga za firime ya coating hamwe no gufatana hagati ya firime yo gutwikira hamwe na substrate, kunoza ubunyangamugayo, kurwanya ikirere, aside na alkali birwanya igifuniko, kandi bitezimbere irangi rya firime.Bikoreshejwe hejuru yurukuta rwinyuma, birashobora kunoza ubushyuhe bwarwo, kurwanya ububi, kurwanya imirasire nibindi bintu.

Ifu ya sericite isukuye irashobora kongerwamo amarangi yo murwego rwohejuru kugirango isimbuze ifu ya zinc, ifu ya aluminium, ifu ya titanium, nibindi. Ifu ya sericite yashegeshwe yakoreshejwe cyane mumavuta asanzwe yamavuta ya rubanda, ariko amata ya butadiene, propylene, acetate ya polyvinyl.Amata y'ibinure n'amata ya acrylic hamwe nandi marangi yo kurukuta imbere, hamwe nimodoka, ipikipiki, irangi ryubwato, nibindi.

Nyuma yo kongeramo ifu ya supericine ya sericite muburyo bwibyuma byubaka umuriro, ibintu bifitanye isano biratera imbere cyane.Wongeyeho ifu ya sericite yahinduwe na agent ya titanate, igipimo cyo kurwanya ubushyuhe bwo gutwika umuriro cyiyongereyeho 25 ℃, kurwanya amazi Umupaka wiyongereye kuva kuri 28h ukagera kuri 47h, kandi imbaraga zububiko zongerewe kuva 0.45MPa zikagera kuri 1.44MPa.

Ongeramo ingano ikwiye yifu ya sericite ya pisitori kumashanyarazi ihindura ingese irashobora kongera ubushyuhe, guhangana nikirere, kurwanya amazi, kurwanya ruswa hamwe nubukanishi bwuzuye bwa firime.

Nyuma yo kongeramo ifu ya ultra-nziza ya sericite kuri anti-ruswa, gukomera hejuru, guhinduka, gufatira hamwe no kurwanya ingaruka za firime ya coating;Muri icyo gihe, irashobora gusimbuza cyangwa gusimbuza igice cya dioxyde ya titanium muburyo bwo gutwikira kugirango igabanye ibiciro bitagize ingaruka kumikorere.
