I-Mica powder iyiminerali engeyona eyensimbi equkethe izingxenye eziningi, ikakhulukazi i-SiO2, enokuqukethwe ngokuvamile okungaba ngu-49% kanye nokuqukethwe kwe-Al2O3 okungaba ngu-30%.I-Mica powder inokunwebeka okuhle nokuqina.Kuyisithasiselo esihle kakhulu esinezici ezinjengokugqumisa, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, ukumelana nokugqwala, nokunamathela okuqinile.Isetshenziswa kabanzi ezimbonini ezifana nezinto zikagesi, ama-electrode wokushisela, irabha, amapulasitiki, ukwenza amaphepha, upende, okokunamathela, okombala, izitsha zobumba, izimonyo, izinto zokwakha ezintsha, njll., ngezicelo ezibanzi kakhulu.Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, abantu baye bavula imikhakha emisha yokufaka izicelo.I-Mica powder iyisakhiwo se-silicate esinezingqimba esihlanganisa izingqimba ezimbili ze-silica tetrahedra ehlanganiswe nongqimba olulodwa lwe-aluminium oxide octahedra, okwenza ungqimba lwe-silica oyinhlanganisela.Iqhekeke ngokuphelele, ekwazi ukuhlukaniswa ibe amashidi amancane kakhulu, anobukhulu obufika ku-1 μ Ngezansi m (ngokweqile, inganqunywa ku-0.001) μ m) , ngesilinganiso esikhulu sobubanzi kuya kubukhulu;I-chemical formula ye-mica powder crystal ithi: K0.5-1 (Al, Fe, Mg) 2 (SiAl) 4O10 (OH) 2 ▪ I-NH2O, ukwakheka kwamakhemikhali okujwayelekile: SiO2: 43.13-49.04%, Al2O3: 27.93-37.44% , K2O+Na2O: 9-11%, H2O: 4.13-6.12%.

I-Mica powder ingeyamakristalu e-monoclinic, asesimweni sezikali futhi ane-silky luster (i-muscovite ine-glass luster).Amabhulokhi ahlanzekile ampunga, i-purple rose, emhlophe, njll., anesilinganiso sobukhulu kuya ku-80, amandla adonsela phansi angu-2.6-2.7, ubulukhuni obungu-2-3, ukunwebeka okuphezulu, ukuguquguquka, ukumelana nokugqokwa okuhle nokumelana nokugqoka. ;Ukufakwa kwe-acid ukumelana nokushisa, kunzima ukukuncibilika ezixazululweni ze-acid-base, futhi kuzinzile kumakhemikhali.Idatha yokuhlola: i-elastic modulus 1505-2134MPa, ukumelana nokushisa 500-600 ℃, conductivity ezishisayo 0.419-0.670W.(mK), ukufakwa kukagesi 200kv/mm, ukumelana nemisebe 5 × 1014 i-neutron eshisayo/cm irradiance.

Ngaphezu kwalokho, ukwakheka kwamakhemikhali, ukwakheka, kanye nesakhiwo se-mica powder kufana nalokhu kwe-kaolin, futhi ibuye ibe nezici ezithile zamaminerali obumba, njengokuhlakazeka okuhle nokumiswa emithonjeni ye-aqueous kanye nezinyibilikisi eziphilayo, umbala omhlophe, izinhlayiya ezinhle, nokunamathela.Ngakho-ke, i-mica powder inezici eziningi zazo zombili i-mica kanye namaminerali obumba.

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

I-1, Ubumhlophe be-mica powder abuphezulu, mayelana ne-75. Ngivame ukuthola imibuzo evela kumakhasimende, ethi ubumhlophe be-mica powder buzungeze i-90. Ngaphansi kwezimo ezijwayelekile, ubumhlophe be-mica powder ngokuvamile abukho phezulu, kuphela nxazonke ze-75. Uma i-doped namanye ama-fillers afana ne-calcium carbonate, i-talc powder, njll., ubumhlophe buzothuthukiswa kakhulu.

I-2, i-Mica powder inesakhiwo esingenalutho.Thatha ibhika, engeza u-100ml wamanzi ahlanzekile, bese ugoqa ngentonga yengilazi ukuze ubone ukuthi ukumiswa kwempuphu ye-mica kuhle kakhulu;Amanye ama-fillers afaka i-powder esobala, i-talc powder, i-calcium carbonate neminye imikhiqizo, kodwa ukusebenza kwabo kokumiswa akukuhle kakhulu njenge-mica powder.

3. Faka inani elincane laso esihlakaleni sakho, esinomphumela omncane we-pearlescent.I-Mica powder, ikakhulukazi i-sericite powder, inomphumela othile we-pearlescent futhi isetshenziswa kabanzi ezimbonini ezifana nezimonyo, okokugqoka, amapulasitiki, irabha, njll.

Izicelo eziyinhloko ze-mica powder kuma-coatings.

Ukusetshenziswa kwe-mica powder kuma-coatings kubonakala ikakhulukazi kulezi zici ezilandelayo:

1. Umthelela wokuvimbela: Izigcwalisi ezifana neshidi zakha ilungiselelo eliyisisekelo eliqondile elihambisanayo ngaphakathi kwefilimu kapende, futhi ukungena kwamanzi nezinye izinto ezigqwalayo kufilimu kapende kuvinjwe ngokuqinile.Uma kusetshenziswa impushana ye-sericite yekhwalithi ephezulu (isilinganiso sobubanzi nobukhulu be-chip okungenani izikhathi ezingu-50, okungcono izikhathi ezingaphezu kuka-70), isikhathi sokungena kwamanzi nezinye izinto ezigqwalayo ngefilimu kapende ngokuvamile sinwetshwa izikhathi ezintathu.Ngenxa yokuthi ama-sericite powder fillers ashibhile kakhulu kunama-resin akhethekile, anenani eliphakeme kakhulu lobuchwepheshe nezomnotho.Ukusetshenziswa kwekhwalithi ephezulu ye-sericite powder kuyindlela ebalulekile yokuthuthukisa ikhwalithi nokusebenza kwezingubo zokulwa nokubola kanye nezindonga zangaphandle zodonga.Phakathi nenqubo yokumboza, ama-sericite chips abhekana nokungezwani kwendawo ngaphambi kokuba ifilimu kapende iqiniswe, yenze ngokuzenzakalelayo isakhiwo esihambisana namanye kanye nangaphezulu kwefilimu kapende.Lolu hlelo lwesendlalelo ngongqimba, olunomumo walo oluqonde ngqo lapho izinto ezonakalisayo zingena khona efilimini kapende, lunomphumela osebenza kakhulu wokuvinjwa.
2. Ukuthuthukisa izici ezingokomzimba nemishini yefilimu kapende: Ukusetshenziswa kwe-sericite powder kungathuthukisa uchungechunge lwezakhiwo zomzimba nemishini yefilimu kapende.Isihluthulelo yizici ze-morphological of the filler, okuyisilinganiso sobubanzi nobukhulu bokugcwalisa okufana neshidi kanye nesilinganiso sobude nobubanzi bokugcwalisa okune-fibrous.Isigcwalisi esiyimbudumbudu, njengesihlabathi netshe kukhonkolo, sidlala indima yokuqinisa ekuqiniseni imigoqo yensimbi.
3. Ukuthuthukisa ukumelana nokugqoka kwefilimu yepende: Ukuqina kwe-resin ngokwayo kulinganiselwe, futhi amandla okugcwalisa amaningi nawo awaphakeme (njenge-talc powder).Ngokuphambene nalokho, i-sericite ingenye yezingxenye ze-granite, ezinobunzima obuphezulu namandla omshini.Ngakho-ke, ukwengeza i-sericite powder njenge-filler enamathela kungathuthukisa kakhulu ukumelana kwayo nokugqoka.Izingubo eziningi zezimoto, okomgwaqo, okokunqanda ukugqwala kwemishini, nezindonga zodonga zisebenzisa impushana ye-sericite.
4. Ukusebenza kwe-insulation: I-Sericite inokumelana okuphakeme kakhulu futhi yona ngokwayo iyinto enhle kakhulu yokuvikela.Yakha inkimbinkimbi ene-organic silicon resin noma i-organic silicon boron resin futhi iyiguqule ibe i-ceramic material enamandla okusebenza kahle nokusebenza kokushisa lapho ihlangabezana namazinga okushisa aphezulu.Ngakho-ke, izintambo namakhebuli enziwe ngalolu hlobo lwento efakwayo zisagcina isimo sazo sokuqala sokwahlukanisa ngisho nangemva kokushiswa ngomlilo.Kubaluleke kakhulu ezimayini, imigudu, izakhiwo ezikhethekile, izikhungo ezikhethekile, njll.
5. I-flame retardant: Impushana ye-Sericite iyisigcwali esibalulekile esibuyisela amalangabi.Uma kuhlanganiswa nama-organic halogen flame retardants, i-flame retardant ne-fire coatings ingalungiswa.
6. Ukumelana ne-UV kanye ne-infrared: I-Sericite isebenza kahle kakhulu ekuvikeleni imisebe ye-ultraviolet kanye ne-infrared.Ngakho-ke ukwengeza impushana ye-sericite emanzi enamathelayo kungathuthukisa kakhulu ukumelana ne-UV yefilimu kapende futhi kubambezele ukuguga kwayo.Ukusebenza kwayo kwe-infrared shielding kusetshenziselwa ukulungisa izinto zokufakelwa kanye nokufakwa (njenge-coatings).
7. Imisebe eshisayo kanye nezinga lokushisa eliphezulu: I-Sericite inekhono elihle lemisebe ye-infrared, njengokuhlanganiswa ne-iron oxide, engadala imiphumela emihle kakhulu yemisebe yokushisa.
8. Ukuvala umsindo nomphumela wokumunca ukushaqeka: I-Sericite ingashintsha ngokuphawulekayo uchungechunge lwemoduli ebonakalayo yezinto ezibonakalayo, yakhe noma iguqule i-viscoelasticity yayo.Lolu hlobo lwezinto lumunca kahle amandla okudlidliza, lwenze buthaka amaza okudlidliza namaza omsindo.Ngaphezu kwalokho, ukuboniswa okuphindaphindiwe kwamagagasi okudlidliza namaza omsindo phakathi kwama-mica chips nakho kwenza amandla awo abe buthaka.I-Sericite powder iphinde isetshenziselwe ukulungisa i-soundproofing, i-soundproofing, kanye nezingubo ezidonsa ukushaqeka.
