Ifu ya Mika ni minerval idafite ubutare irimo ibice byinshi, cyane cyane SiO2, hamwe nibirimo muri rusange hafi 49% naho Al2O3 ikaba igera kuri 30%.Ifu ya Mika ifite elastique nziza no gukomera.Ninyongera nziza cyane hamwe nibiranga nko gukingirwa, kurwanya ubushyuhe bwinshi, aside irwanya alkali, kurwanya ruswa, hamwe no gufatira hamwe.Ikoreshwa cyane mu nganda nk'ibikoresho by'amashanyarazi, gusudira electrode, reberi, plastike, gukora impapuro, irangi, impuzu, pigment, ububumbyi, amavuta yo kwisiga, ibikoresho bishya byubaka, nibindi, hamwe nibisabwa cyane.Hamwe niterambere ryiterambere rya siyanse nikoranabuhanga, abantu bafunguye byinshi bishya byo gukoresha.Ifu ya Mica nuburyo bwa silikatike igizwe nuburyo bubiri bwa silika tetrahedra sandwiched hamwe nigice kimwe cya oxyde ya aluminium octahedra, ikora silika igizwe.Yuzuye neza, ishoboye kwigabanyamo amashuka yoroheje cyane, hamwe nubugari bwa 1 μ Munsi ya m (mubyukuri, irashobora gucibwa kugeza 0.001) μ m), hamwe na diameter nini nuburinganire;Imiti yimiti ya kirisita ya mika ni: K0.5-1 (Al, Fe, Mg) 2 (SiAl) 4O10 (OH) 2 ▪ NH2O, imiti rusange: SiO2: 43.13-49.04%, Al2O3: 27.93-37.44% , K2O + Na2O: 9-11%, H2O: 4.13-6.12%.

Ifu ya Mika ni iya kristu ya monoclinike, iri mu munzani kandi ifite urumuri rwinshi (muscovite ifite ikirahure).Ibice bisukuye ni imvi, roza yumutuku, umweru, nibindi, hamwe na diametre nuburinganire bwa> 80, uburemere bwihariye bwa 2.6-2.7, ubukana bwa 2-3, ubworoherane bukabije, guhinduka, kwihanganira kwambara no kwihanganira kwambara ;Kwirinda ubushyuhe, biragoye gushonga mubisubizo bya acide, kandi bihamye.Amakuru yikizamini: modulus ya elastike 1505-2134MPa, kurwanya ubushyuhe 500-600 ℃, ubushyuhe bwumuriro 0.419-0.670W..

Byongeye kandi, imiterere yimiti, imiterere, nimiterere yifu ya mika bisa nibya kaolin, kandi ifite kandi ibintu bimwe na bimwe biranga amabuye y'agaciro y'ibumba, nko gutatanya neza no guhagarikwa mu bitangazamakuru byo mu mazi hamwe n'umuti ukomoka ku binyabuzima, ibara ryera, ibice byiza, no gukomera.Kubwibyo, ifu ya mika ifite ibintu byinshi biranga mika nubutare bwibumba.

Kumenyekanisha ifu ya mika biroroshye cyane.Ukurikije ubunararibonye, ​​muri rusange hari uburyo bukurikira bwo kwifashisha gusa:

1 、 Umweru w'ifu ya mika ntabwo uri hejuru, hafi 75. Nkunze kwakira ibibazo kubakiriya, nkavuga ko umweru w'ifu ya mika uri hafi 90. Mubihe bisanzwe, umweru w'ifu ya mika muri rusange ntabwo ari mwinshi, gusa ni 75. Niba ikozwe hamwe nibindi byuzuza nka calcium karubone, ifu ya talc, nibindi, umweru uzatera imbere cyane.

2 powder Ifu ya Mika ifite imiterere idahwitse.Fata inzoga, ongeramo 100ml y'amazi meza, hanyuma ushyire hamwe n'inkoni y'ibirahure kugirango urebe ko guhagarika ifu ya mika ari byiza cyane;Ibindi byuzuza birimo ifu ibonerana, ifu ya talc, karubone ya calcium nibindi bicuruzwa, ariko imikorere yabyo yo guhagarika ntabwo ari nziza nkifu ya mika.

3 amount Koresha umubare muto wacyo ku kuboko kwawe, bifite ingaruka nkeya.Ifu ya Mika, cyane cyane ifu ya sericite, igira ingaruka nziza ya pearlescent kandi ikoreshwa cyane munganda nka cosmetike, kote, plastike, reberi, nibindi. Niba ifu ya mika yaguzwe ifite ingaruka mbi cyangwa idafite isaro, hagomba kwitonderwa muriki gihe.

Ibyingenzi byingenzi byifu ya mika mubitambaro.

Gukoresha ifu ya mika mubitambaro bigaragarira cyane cyane mubice bikurikira:

1. Ingaruka ya bariyeri: Urupapuro rumeze nk'urupapuro rugizwe na gahunda yibanze igereranijwe muri firime irangi, kandi kwinjira mumazi nibindi bintu byangirika muri firime irangi birahagaritswe cyane.Iyo ifu ya sericite yo mu rwego rwohejuru ikoreshwa (igipimo cya diameter nuburinganire bwa chip byibuze inshuro 50, byaba byiza inshuro zirenga 70), igihe cyo kwinjira mumazi nibindi bintu byangirika binyuze muri firime irangi byongerwa inshuro eshatu.Bitewe nuko serisite yuzuza ifu yuzuye ihendutse cyane kuruta ibisigazwa bidasanzwe, bifite agaciro gakomeye mubuhanga nubukungu.Gukoresha ifu ya sericite yujuje ubuziranenge nuburyo bwingenzi bwo kuzamura ireme n’imikorere yimyenda irwanya ruswa hamwe n’urukuta rwo hanze.Mugihe cyo gutwikira, chipic sericite ziterwa nubutaka mbere yuko firime irangi ikomera, ihita ikora imiterere ihwanye kandi ndetse no hejuru ya firime irangi.Uru rupapuro ukurikije gahunda, hamwe nicyerekezo cyarwo neza neza nicyerekezo aho ibintu byangirika byinjira muri firime irangi, bifite ingaruka nziza cyane.
2. Kunoza imiterere yumubiri nubukanishi bwa firime irangi: Gukoresha ifu ya sericite irashobora kunoza urukurikirane rwimiterere yumubiri nubukanishi bwa firime irangi.Urufunguzo ni morfologiya iranga uwuzuza, aribyo diameter nuburinganire bwikigereranyo cyurupapuro rumeze nkuburebure hamwe nuburebure na diameter igereranyo ya fibrous yuzuza.Uzuza granular, nkumucanga namabuye muri beto, bigira uruhare runini mugushimangira ibyuma.
3. Kunoza imyambarire ya firime yo gusiga irangi: Ubukomere bwa resin ubwabwo ni buke, kandi imbaraga zuzuza nazo ntizihagije (nka poro ya talc).Ibinyuranye na byo, serisite ni kimwe mu bigize granite, hamwe n'ubukomezi bukomeye n'imbaraga za mashini.Kubwibyo, kongeramo ifu ya sericite nkuwuzuza muri coating irashobora kunoza cyane imyambarire yayo.Imyenda myinshi yimodoka, ibara ryumuhanda, imashini irwanya ruswa, hamwe ninkuta zikoresha ifu ya sericite.
4. Imikorere yo gukumira: Sericite ifite imbaraga zo kurwanya cyane kandi ubwayo ni ibikoresho byiza cyane.Ikora urwego rugizwe na silicon organic resin cyangwa organic silicon boron resin ikayihindura mubintu bya ceramic hamwe nimbaraga nziza za mashini hamwe nibikorwa byokwirinda mugihe uhuye nubushyuhe bwinshi.Kubwibyo, insinga ninsinga bikozwe muri ubu bwoko bwibikoresho byo kubika ibintu biracyakomeza imiterere yabyo mbere na nyuma yo gutwikwa mumuriro.Ningirakamaro cyane kubirombe, tunel, inyubako zidasanzwe, ibikoresho bidasanzwe, nibindi.
5. Flame retardant: Ifu ya Sericite niyuzuza flame retardant yuzuza.Niba uhujwe na organic halogen flame retardants, flame retardant hamwe nudukingirizo twumuriro.
6. Kurwanya UV na infragre: Sericite ifite imikorere myiza mukurinda ultraviolet nimirasire yimirasire.Kwongeramo ifu ya sericite itose kumyenda yo hanze irashobora kunoza cyane kurwanya UV ya firime yamabara kandi bigatinda gusaza.Imikorere ya infragre ikingira ikoreshwa mugutegura ibikoresho byo kubika no kubika (nka coatings).
7. Imirasire yubushyuhe hamwe nubushyuhe bwo hejuru: Sericite ifite ubushobozi bwimirasire yimirasire myiza, nko gufatanya na oxyde de fer, ishobora gutera ingaruka nziza zumuriro.
8. Ijwi ryokwirinda amajwi hamwe ningaruka zo gukurura: Sericite irashobora guhindura cyane urukurikirane rwibintu bifatika byumubiri, gukora cyangwa guhindura viscoelasticité.Ubu bwoko bwibikoresho bikurura neza imbaraga zo kunyeganyega, bigabanya imbaraga zinyeganyega hamwe nijwi ryamajwi.Byongeye kandi, gusubiramo kenshi kwinyeganyeza hamwe nijwi ryijwi hagati ya mika chip nabyo bigabanya imbaraga zabo.Ifu ya sericite nayo ikoreshwa mugutegura amajwi, kutagira amajwi, hamwe no gukurura ibishishwa.
