Sericite

Sericite ke diminerale tsa silicate tse nang le sebopeho se setle se kang sekala.E na le likaroloana tse ntle le hydration e bonolo.Ho na le phetoho e fokolang ea cation mohahong.Palo ea K + e tlatsitsoeng ka har'a interlayer e ka tlase ho ea muscovite, kahoo potassium e ka har'a metsoako ea lik'hemik'hale e tlaase hanyenyane ho feta ea muscovite.Empa metsi a na le metsi a mangata ho feta a muscovite, kahoo batho ba bang ba e bitsa polysilicon, potassium-e futsanehileng, mica ea letsopa e nang le metsi.

Kopo ea sericite tšimong ea ho roala

Superfine sericite phofo ke mofuta o mocha oa li-filler tse sebetsang, tse sebelisoang haholo lefapheng la lipente le liphahlo.Hobane phofo ea sericite e na le sebopeho se setle sa sekala, bokaholimo ba kristale bo boreleli, karo-karolelano e kholo ea bophara ho isa ho botenya, bosoeu bo phahameng, thepa ea lik'hemik'hale e tsitsitseng, boima bo bobebe, boreleli, ho kenella le ho hanyetsa mahlaseli, e sebelisoa haholo lipenteng tse fapaneng tsa boemo bo holimo, mafome- bopaki, masela a sa cheng le a thibelang kutu.e ntle ea pigment filler.Ka lebaka la sebopeho se entsoeng ka sericite, filimi ea pente e ka bolokoa nako e telele ntle le ho fela ka mor'a hore likaroloana tsa dae li kene ka har'a li-lattice tsa sericite.

Sebopeho sa lik'hemik'hale tsa sericite se tšoana le sa li-filler tsa setso tse kang talc, kaolin, wollastonite, joalo-joalo, 'me ka bobeli ke tsa liminerale tsa silicate, empa sebopeho sa eona se ikhethang le thepa e khethehileng li etsa hore li ame thepa e amehang ea li-coatings ka likopo. mohlala, ho E na le phello ea ntlafatso ea sefofane penteng.Ho sebelisa superfine sericite phofo ho nka sebaka sa li-filler tsa setso ka har'a litlolo tsa ho roala ho ka ntlafatsa haholo matla a filimi ea ho roala le ho khomarela pakeng tsa filimi ea ho roala le substrate, ho ntlafatsa botšepehi, ho hanyetsa boemo ba leholimo, ho hanyetsa acid le alkali ea ho roala, le ho ntlafatsa pente filimi boreleli.E sebelisoa ho marako a ka ntle a lerako, e ka ntlafatsa ho hanyetsa mocheso, ho thibela litšila, ho thibela mahlaseli a mahlaseli le lintho tse ling.

Sericite phofo e kolobisitsoeng ka metsi e ka eketsoa lipenteng tsa boemo bo holimo ho nkela phofshoana ea zinki sebaka, phofo ea aluminium, phofo ea titanium, joalo-joalo. Phofo ea sericite e kolobisitsoeng ka metsi e 'nile ea sebelisoa haholo penteng e tloaelehileng ea linseed civil pente, lebese la butadiene, propylene, polyvinyl acetate.Lebese la mafura le lebese la acrylic le lipente tse ling tsa ka hare tsa lebota, hammoho le koloi, sethuthuthu, pente ea likepe, joalo-joalo.

Kamora ho eketsa phofshoana ea sericite ea superfine ho tšepe ea tšepe e sa keneleng mollo, thepa ea eona e amanang le eona e ntlafatsoa haholo.Ho eketsa phofo ea sericite e fetotsoeng ke titanate coupling agent, moeli oa ho hanyetsa mocheso oa ho roala mollo o eketseha ka 25 ℃, ho hanyetsa metsi Moeli o eketseha ho tloha 28h ho ea ho 47h, 'me matla a tlamahano a eketseha ho tloha 0.45MPa ho ea 1.44MPa.

Ho kenyelletsa phofo ea superfine sericite ho mafome a phetolo ea mafome ho ka matlafatsa ho hanyetsa mocheso, ho hanyetsa boemo ba leholimo, ho hanyetsa metsi, ho hanyetsa kutu le thepa e feletseng ea mochine oa filimi ea ho roala.

Ka mor'a ho eketsa phofo ea sericite ea ultra-fine ho li-anti-corrosion coatings, ho thatafala ha holim'a metsi, ho feto-fetoha ha maemo, ho khomarela le ho hanyetsa phello ea filimi ea ho roala ho ntlafatsoa;Ka nako e ts'oanang, e ka nka sebaka sa titanium dioxide kapa ka karolo e itseng ka mokhoa oa ho roala ho fokotsa litšenyehelo ntle le ho ama ts'ebetso ea ho roala.
