I-Mica powder iyiminerali engeyona eyensimbi equkethe izingxenye eziningi, ikakhulukazi i-SiO2, enokuqukethwe okuvame ukuba ngu-49% kanye nokuqukethwe kwe-Al2O3 okucishe kube ngu-30%. I-Mica powder inokuqina okuhle nokuqina. Iyisengezo esihle kakhulu esinezici ezifana nokushisa, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, ukumelana nokugqwala, kanye nokunamathela okuqinile. Isetshenziswa kabanzi ezimbonini ezifana nezinto zikagesi, ama-electrode okushisela, irabha, amapulasitiki, ukwenza iphepha, upende, izembozo, imibala, izinto zobumba, izimonyo, izinto zokwakha ezintsha, njll., ngezinhlelo zokusebenza ezibanzi kakhulu. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, abantu bavule amasimu amasha okusebenza. I-Mica powder iyisakhiwo se-silicate esinezingqimba ezimbili ze-silica tetrahedra ehlanganiswe nengqimba eyodwa ye-aluminium oxide octahedra, yakha ungqimba lwe-silica oluhlanganisiwe. Ihlukaniswe ngokuphelele, ekwazi ukuhlukana ibe amashidi amancane kakhulu, enobukhulu obufika ku-1 μ Ngaphansi kwe-m (ngokwethiyori, ingasikwa ibe ngu-0.001) μ m), enobubanzi obukhulu nobukhulu; Ifomula yamakhemikhali yekristalu yempuphu ye-mica ithi: K0.5-1 (Al, Fe, Mg) 2 (SiAl) 4O10 (OH) 2 ▪ NH2O, ukwakheka kwamakhemikhali okuvamile: SiO2: 43.13-49.04%, Al2O3: 27.93-37.44%, K2O+Na2O: 9-11%, H2O: 4.13-6.12%.

Impuphu ye-Mica ingeyamakristalu e-monoclinic, asesimweni sezikali futhi anokukhanya okusilika (i-muscovite inokukhanya kwengilazi). Amabhulokhi amsulwa ampunga, i-rose ensomi, emhlophe, njll., enesilinganiso sobubanzi nobukhulu obungu->80, amandla adonsela phansi athile angu-2.6-2.7, ubulukhuni obungu-2-3, ukuqina okuphezulu, ukuguquguquka, ukumelana okuhle nokuguguleka; Ukushisa okumelana nokushisa, okunzima ukuncibilika ezixazululweni zesisekelo se-acid, futhi okuzinzile ngamakhemikhali. Idatha yokuhlola: i-modulus elastic 1505-2134MPa, ukumelana nokushisa okungu-500-600 ℃, ukuqhuba ukushisa okungu-0.419-0.670W. (mK), ukushisa kagesi okungu-200kv/mm, ukumelana nemisebe engu-5 × 1014 thermal neutron/cm irradiance.

Ngaphezu kwalokho, ukwakheka kwamakhemikhali, isakhiwo, kanye nesakhiwo sempuphu ye-mica kufana nokwe-kaolin, futhi inezici ezithile zamaminerali obumba, njengokuhlakazeka okuhle kanye nokumiswa emanzini kanye nezinyibilikisi eziphilayo, umbala omhlophe, izinhlayiya ezincane, kanye nokunamathela. Ngakho-ke, impuphu ye-mica inezici eziningi zamaminerali e-mica kanye nobumba.

Ukuhlonza i-mica powder kulula kakhulu. Ngokusekelwe kokuhlangenwe nakho, ngokuvamile kunezindlela ezilandelayo zokubhekisela kuwe kuphela:

1、 Ubumhlophe bempuphu ye-mica abuphakeme, cishe ngama-75. Ngivame ukuthola imibuzo evela kumakhasimende, ethi ubumhlophe bempuphu ye-mica bucishe bube ngama-90. Ngaphansi kwezimo ezijwayelekile, ubumhlophe bempuphu ye-mica ngokuvamile abuphakeme, cishe ngama-75 kuphela. Uma ixutshwe nezinye izithasiselo ezifana ne-calcium carbonate, i-talc powder, njll., ubumhlophe buzothuthukiswa kakhulu.

2、 Impuphu ye-Mica inesakhiwo esiqhekekile. Thatha i-beaker, engeza u-100ml wamanzi ahlanzekile, bese uvuselela ngenduku yengilazi ukuze ubone ukuthi ukumiswa kwempuphu ye-mica kuhle kakhulu; Ezinye izigcwalisi zifaka impuphu ecacile, i-talc powder, i-calcium carbonate neminye imikhiqizo, kodwa ukusebenza kwayo kokumiswa akukuhle njengempuphu ye-mica.

3、 Faka inani elincane layo esihlakaleni sakho, elinomphumela omncane we-pearlescent. I-Mica powder, ikakhulukazi i-sericite powder, inomphumela othile we-pearlescent futhi isetshenziswa kabanzi ezimbonini ezifana nezimonyo, izembozo, amapulasitiki, irabha, njll. Uma i-mica powder ethengiwe inomphumela omubi noma ingenayo i-pearlescent, kufanele kunakwe ngalesi sikhathi.

Ukusetshenziswa okuyinhloko kwempuphu ye-mica ekumbozweni.

Ukusetshenziswa kwe-mica powder ezimbozweni kubonakala kakhulu kulezi zici ezilandelayo:

1. Umphumela Wokuvinjelwa: Ama-filler afana neshidi akha uhlelo oluyisisekelo oluhambisanayo ngaphakathi kwefilimu yopende, futhi ukungena kwamanzi nezinye izinto ezibolayo efilimini yopende kuvinjiwe kakhulu. Uma kusetshenziswa i-sericite powder esezingeni eliphezulu (isilinganiso sobubanzi nobukhulu be-chip okungenani izikhathi ezingama-50, okungcono izikhathi ezingaphezu kuka-70), isikhathi sokungena kwamanzi nezinye izinto ezibolayo ngefilimu yopende ngokuvamile sandiswa kathathu. Ngenxa yokuthi ama-sericite powder fillers ashibhile kakhulu kune-resins ekhethekile, anenani eliphezulu kakhulu lobuchwepheshe nezomnotho. Ukusetshenziswa kwe-sericite powder esezingeni eliphezulu kuyindlela ebalulekile yokuthuthukisa ikhwalithi kanye nokusebenza kwezingubo zokulwa nokugqwala kanye nezingubo zodonga zangaphandle. Ngesikhathi senqubo yokumboza, ama-sericite chips abhekana nokucindezeleka kobuso ngaphambi kokuba ifilimu yopende iqine, yakha ngokuzenzakalelayo isakhiwo esihambisanayo kanye nobuso befilimu yopende. Lolu lungiselelo lwesendlalelo ngesendlalelo, olunendlela yalo eqondile ngqo lapho izinto ezibolayo zingena khona efilimini yopende, lunomphumela wokuvimbela osebenza kahle kakhulu.
2. Ukuthuthukisa izakhiwo zomzimba nezemishini zefilimu yopende: Ukusetshenziswa kwempuphu ye-sericite kungathuthukisa uchungechunge lwezakhiwo zomzimba nezemishini zefilimu yopende. Isihluthulelo yizici zesimo sefilimu yokugcwalisa, okungukuthi isilinganiso sobubanzi nobukhulu befilimu efana neshidi kanye nesilinganiso sobude nobubanzi befilimu yokugcwalisa enemicu. I-granular filler, njengesihlabathi netshe kukhonkolo, idlala indima yokuqinisa ekuqiniseni imigoqo yensimbi.
3. Ukuthuthukisa ukumelana nokuguguleka kwefilimu yopende: Ubulukhuni be-resin ngokwayo bulinganiselwe, futhi amandla ezigcwalisi eziningi nawo awaphezulu (njenge-talc powder). Ngokuphambene nalokho, i-sericite ingenye yezingxenye ze-granite, enobulukhuni obuphezulu namandla omshini. Ngakho-ke, ukwengeza i-sericite powder njengesigcwalisi ephepheni kungathuthukisa kakhulu ukumelana kwayo nokuguguleka. Iningi lezigqoko zemoto, izigqoko zomgwaqo, izigqoko zokulwa nokugqwala komshini, kanye nezigqoko zodonga zisebenzisa i-sericite powder.
4. Ukusebenza kokuvikela: I-Sericite inokumelana okuphezulu kakhulu futhi ngokwayo iyinto yokuvikela enhle kakhulu. Yakha inhlanganisela nge-organic silicon resin noma i-organic silicon boron resin futhi iyiguqula ibe yinto yobumba enamandla amahle okusebenza kanye nokusebenza kokuvikela lapho ibhekene namazinga okushisa aphezulu. Ngakho-ke, izintambo nezintambo ezenziwe ngalolu hlobo lwezinto zokuvikela zisagcina isimo sazo sokuqala sokuvikela ngisho nangemva kokushiswa emlilweni. Kubaluleke kakhulu ezimayini, emihubheni, ezakhiweni ezikhethekile, ezindaweni ezikhethekile, njll.
5. Isivimbeli somlilo: Impuphu ye-Sericite iyisithako esibalulekile sokugcwalisa isivimbeli somlilo. Uma ihlanganiswe nezivimbeli zomlilo ze-halogen eziphilayo, kungalungiswa izimbozo ezivimbeli somlilo kanye nezimbozo ezingashi.
6. Ukumelana ne-UV kanye ne-infrared: I-Sericite isebenza kahle kakhulu ekuvikeleni emisebeni ye-ultraviolet kanye ne-infrared. Ngakho-ke ukwengeza i-sericite powder emanzi ezimbozweni zangaphandle kungathuthukisa kakhulu ukumelana kwe-UV kwefilimu yopende futhi kulibazise ukuguga kwayo. Ukusebenza kwayo kokuvikela kwe-infrared kusetshenziselwa ukulungiselela izinto zokuvikela kanye nokuvikela (njengezimbozo).
7. Imisebe yokushisa kanye nezingubo zokushisa okuphezulu: I-Sericite inekhono elihle lemisebe ye-infrared, njengokuhlanganiswa ne-iron oxide, okungadala imiphumela emihle kakhulu yemisebe yokushisa.
8. Ukuvimbela umsindo kanye nomphumela wokumunca ukushaqeka: I-Sericite ingashintsha kakhulu uchungechunge lwezimo ezibonakalayo zezinto, yakha noma ishintshe ukuqina kwazo. Lolu hlobo lwezinto lumunca kahle amandla okudlidliza, lwenza buthaka amagagasi okudlidliza kanye namagagasi omsindo. Ngaphezu kwalokho, ukubonakaliswa okuphindaphindiwe kwamagagasi okudlidliza kanye namagagasi omsindo phakathi kwama-mica chips nakho kwenza buthaka amandla awo. I-Sericite powder isetshenziselwa futhi ukulungiselela ukuvimbela umsindo, ukuvimbela umsindo, kanye nokugqoka okumunca ukushaqeka.
