Mica powder is a non-metallic mineral ine zvinhu zvakawanda, kunyanya SiO2, ine zvinyorwa zvinowanzopoteredza 49% uye Al2O3 zvinyorwa zvakakomberedza 30%.Mica poda ine elasticity yakanaka uye kuoma.Iyo yakanakisa yekuwedzera ine hunhu hwakaita senge insulation, yakakwirira tembiricha kuramba, acid uye alkali resistance, corrosion resistance, uye kunamatira kwakasimba.Inoshandiswa zvakanyanya mumaindasitiri akadai semidziyo yemagetsi, welding electrode, rabha, mapurasitiki, kugadzira mapepa, pendi, machira, pigment, ceramics, cosmetics, zvinhu zvitsva zvekuvaka, nezvimwe, zvine maapplication akanyanya.Nekuenderera mberi kwekusimudzira kwesainzi uye tekinoroji, vanhu vakavhura mamwe minda mitsva yekushandisa.Mica powder chimiro che silicate chine mativi maviri e silica tetrahedra akaiswa sandwich neimwe layer yealuminum oxide octahedra, achigadzira mubatanidzwa silica layer.Yakatsemurwa zvachose, inokwanisa kupatsanurwa kuita mapepa akaonda zvakanyanya, nehupamhi hunosvika 1 μ Pazasi m (inoretically, inogona kutemwa kusvika 0.001) μ m) , ine dhayamita yakakura kusvika kune ukobvu ratio;Mushonga wemakemikari wemica powder crystal ndeye: K0.5-1 (Al, Fe, Mg) 2 (SiAl) 4O10 (OH) 2 ▪ NH2O, general chemical composition: SiO2: 43.13-49.04%, Al2O3: 27.93-37.44% , K2O+Na2O: 9-11%, H2O: 4.13-6.12%.
Mica poda ndeyemonoclinic makristasi, ayo ari muchimiro chezviyero uye ane silky luster (muscovite ine girazi rinopenya).Iwo mabhuroko akachena igrey, yepepuru rose, chena, nezvimwewo, ine dhayamita kusvika kugobvu reshiyo ye> 80, yakananga giravhiti ye2.6-2.7, kuomarara kwe2-3, kusimba kwepamusoro, kuchinjika, kupfeka kwakanaka uye kuramba kupfeka. ;Insulation inodzivirira kupisa, yakaoma kunyungudika muacid-base solutions, uye kugadzikana kwemakemikari.Test data: elastic modulus 1505-2134MPa, kupisa kuramba 500-600 ℃, thermal conductivity 0.419-0.670W.(mK), magetsi ekudzivirira 200kv/mm, nemwaranzi kuramba 5 × 1014 thermal neutron/cm irradiance.
Pamusoro pezvo, kuumbwa kwekemikari, chimiro, uye chimiro chemica powder yakafanana neiyo kaolin, uye inewo humwe hunhu hwemaminerari evhu, sekupararira kwakanaka uye kumiswa mune aqueous media uye organic zvinonyungudutsa, ruvara ruchena, zvidimbu zvidimbu, uye kunamira.Naizvozvo, mica poda ine akawanda maitiro ezvose mica uye ivhu zvicherwa.
Kuzivikanwa kwe mica powder kuri nyore.Zvichienderana neruzivo, pane kazhinji nzira dzinotevera dzereferensi yako chete:
1, Kuchena kwe mica powder haisi yakakwirira, inenge 75. Ndinowanzogamuchira mibvunzo kubva kune vatengi, ichitaura kuti kuchena kwemica powder inenge yakapoteredza 90. Mumamiriro ezvinhu akajairika, kuchena kwehupfu hwemica kazhinji hakusi kukwirira, kungopoteredza 75 chete. Kana doped nemamwe mafirita akadai se calcium carbonate, talc poda, nezvimwewo, kuchena kuchavandudzwa zvakanyanya.
2, Mica poda ine chimiro chisina kujeka.Tora beaker, uwedzere 100ml yemvura yakachena, uye funganisa negirazi tsvimbo kuti uone kuti kumiswa kwe mica powder yakanaka kwazvo;Mamwe mafirita anosanganisira poda inoonekera, talc poda, calcium carbonate uye zvimwe zvigadzirwa, asi kumiswa kwavo kuita hakuna kunaka semica poda.
3. Isa chikamu chidiki paruoko rwako, icho chine pearlescent mhedzisiro.Mica powder, kunyanya sericite powder, ine imwe pearlescent effect uye inoshandiswa zvakanyanya mumaindasitiri akadai sezvizoro, machira, mapurasitiki, rabha, nezvimwewo.
Iko kushandiswa kukuru kwe mica poda mumachira.
Kushandiswa kwe mica poda mumachira kunonyanya kuratidzwa mune zvinotevera zvinhu:
1. Barrier effect: Mashizha-akaita semafirita anoumba a basic parallel oriented gadziriro mukati mefirimu repende, uye kupinda kwemvura nezvimwe zvinhu zvinoparadza mufirimu repende zvinovharirwa zvakasimba.Kana yemhando yepamusoro sericite poda inoshandiswa (iyo dhayamita kusvika kuhukobvu reshiyo yechip kanenge ka50, zvichida kanopfuura ka70), nguva yekupinda kwemvura uye zvimwe zvinhu zvinoparadza kuburikidza nefirimu repende inowanzowedzerwa katatu.Nekuda kwekuti sericite poda mafirita akachipa zvakanyanya pane akakosha resin, iwo ane yakanyanya hunyanzvi uye yehupfumi kukosha.Kushandiswa kwepamusoro-soro sericite powder inzira inokosha yekuvandudza hutano uye kushanda kwekudzivirira-kupisa uye kunze kwemadziro emadziro.Munguva yekuputira, sericite machipisi anoiswa pasi pekunetsana kwependi firimu repende risati raoma, otomatiki richigadzira chimiro chakafanana kune chimwe uye zvakare nepamusoro pefirimu repende.Iyi layer by layer, ine yakanangana chaizvo nekwairi kunopinda zvinhu zvinoodza mukati mufirimu repende, ine inoshanda zvakanyanya barriers effect.
2. Kuvandudza hutano hwepanyama uye hwemagetsi efirimu yepende: Kushandisa sericite powder kunogona kuvandudza mutsara wehutano hwemuviri uye michina yefirimu yepende.Kiyi ndiyo morphological maitiro ekuzadza, kureva dhayamita kusvika kune ukobvu reshiyo yeshizha-senge yekuzadza uye kureba kusvika kudhayamita reshiyo yefibrous filler.Iyo granular filler, sejecha nedombo mukongiri, inoita basa rekusimbisa mukusimbisa simbi dzesimbi.
3. Kuvandudza kupikisa kupfeka kwefirimu yepende: Kuoma kweresin pachayo kunogumira, uye simba rezvizadza zvakawanda hazvinawo kukwirira (zvakadai se talc powder).Pane zvinopesana, sericite chimwe chezvikamu zvegranite, nehupamhi hwekuoma uye simba remagetsi.Naizvozvo, kuwedzera sericite poda senge yekuzadza mukati mejasi inogona kuvandudza zvakanyanya kusakara kwayo.Mazhinji mabhachi emota, machira emumugwagwa, machira anodzivirira kukora, uye mapendekete emadziro anoshandisa sericite upfu.
4. Insulation performance: Sericite ine yakanyanya kupikisa uye ndiyo pachayo yakanyanya kunaka yekuvharisa zvinhu.Iyo inoumba yakaoma ine organic silicon resin kana organic silicon boron resin uye inoishandura kuita yeceramic zvinhu zvine simba remagetsi uye kushanda kwekudzivirira kana uchisangana nekupisa kwakanyanya.Naizvozvo, waya uye tambo dzakagadzirwa nemhando iyi yekudzivirira zvinhu zvinoramba zvichichengetedza mamiriro ekutanga ekudzivirira kunyangwe mushure mekupiswa mumoto.Izvo zvakakosha kune migodhi, tunnel, zvivakwa zvakakosha, zvivakwa zvakakosha, nezvimwe.
5. Flame retardant: Sericite powder chinhu chinokosha chinopisa moto.Kana yakasanganiswa neorganic halogen flame retardants, inodzoreredza murazvo uye machira asingapindi moto anogona kugadzirwa.
6. UV uye infrared resistance: Sericite ine basa rakanakisa mukudzivirira kurwisa ultraviolet uye infrared mwaranzi.Saka kuwedzera yakanyorova sericite poda kumachira ekunze kunogona kuvandudza zvakanyanya kupikisa kweUV kwefirimu repende uye kunonoka kuchembera.Yayo infrared shielding performance inoshandiswa kugadzirira kusungirira uye kuvharisa zvinhu (senge machira).
7. Thermal mwaranzi uye yakakwirira-tembiricha coatings: Sericite ine yakanaka infrared mwaranzi kugona, akadai musanganiswa nesimbi oxide, izvo zvinogona kugadzira zvakanakisa kupisa nemwaranzi migumisiro.
8. Inzwi rekudzivirira uye kuvhunduka kunobata mhedzisiro: Sericite inogona kushandura zvakanyanya nhevedzano yemuviri moduli yezvinhu, kugadzira kana kushandura viscoelasticity yavo.Rudzi urwu rwezvinhu zvinonyatsotora simba rekuzunguza, rinonetesa masaisai ekudengenyeka uye masaisai eruzha.Uye zvakare, iyo inodzokororwa kuratidzwa kwemafungu ekudengenyeka uye masaisai eruzha pakati pemica chips zvakare inonetesa simba ravo.Sericite poda inoshandiswawo kugadzira machira anodzivirira ruzha, anodzivirira ruzha, uye anonwisa machira.
