Upfu hweMica imineral isiri yesimbi ine zvikamu zvakawanda, kunyanya SiO2, ine huwandu hunowanzoita 49% uye huwandu hweAl2O3 hunosvika 30%. Upfu hweMica hune kusimba kwakanaka uye hune hunyoro. Ichinhu chakanakisa chinowedzera chine hunhu hwakadai sekuputira, kuramba kupisa kwakanyanya, kuramba acid nealkali, kuramba ngura, uye kunamira kwakasimba. Inoshandiswa zvakanyanya mumaindasitiri akadai semidziyo yemagetsi, maerekitironi ekuwelda, rabha, mapurasitiki, kugadzira mapepa, pendi, machira, pigments, ceramics, cosmetics, zvinhu zvitsva zvekuvaka, nezvimwewo, zvine mashandisirwo akafara zvikuru. Nekufambira mberi kwesainzi netekinoroji, vanhu vakavhura nzvimbo itsva dzekushandisa. Upfu hweMica ichimiro che silica chakaiswa muzvikamu zviviri zve silica tetrahedra chakaiswa muchikamu chimwe chealuminium oxide octahedra, ichigadzira chikamu che silica chakabatanidzwa. Chakatsemuka zvachose, chinokwanisa kupatsanurwa kuita mapepa matete zvakanyanya, nehukobvu hunosvika 1 μ Pasi pe m (mupfungwa, chinogona kuchekwa kusvika 0.001) μ m), chine chiyero chikuru chedhayamita neukobvu; Fomura yemakemikari yekristaro yeupfu hwemica ndeiyi: K0.5-1 (Al, Fe, Mg) 2 (SiAl) 4O10 (OH) 2 ▪ NH2O, kuumbwa kwemakemikari kwakajairika: SiO2: 43.13-49.04%, Al2O3: 27.93-37.44%, K2O+Na2O: 9-11%, H2O: 4.13-6.12%.

Upfu hweMica hunowanikwa mumakristaro emonoclinic, ari muchimiro chemakwara uye ane silky luster (muscovite ine girazi luster). Mabhuroko acho akachena igrey, purple rose, chena, nezvimwewo, ane dhayamita kusvika pakukora kwe>80, giravhiti chaiyo ye2.6-2.7, kuomarara kwe2-3, kusimba kwakanyanya, kuchinjika, kuramba kupfeka zvakanaka uye kuramba kupfeka; Kudzivirira kupisa kunodzivirira kupisa, kwakaoma kunyungudika mu acid-base solutions, uye kugadzikana kwemakemikari. Data rekuyedza: elastic modulus 1505-2134MPa, kuramba kupisa 500-600 ℃, thermal conductivity 0.419-0.670W. (mK), kudzivirira magetsi 200kv/mm, kuramba mwaranzi 5 × 1014 thermal neutron/cm irradiance.

Pamusoro pezvo, kuumbwa kwemakemikari, chimiro, uye chimiro cheupfu hwemica zvakafanana nekaolin, uye ine zvimwe zvinhu zvakaita sezvicherwa zvevhu, zvakaita sekupararira zvakanaka uye kusungirirwa mumvura uye zvinonyungudutsa zvakasikwa, ruvara ruchena, zvidimbu zvitete, uye kunamira. Nokudaro, upfu hwemica hune zvinhu zvakawanda zvakaita sezvicherwa zvemica nevhu.

Kuziva upfu hwemica kuri nyore kwazvo. Zvichibva pane zvakaitika, kazhinji kune nzira dzinotevera dzekutarisa chete:

1、 Kuchena kwehupfu hwemica hakuna kukwira, kunenge 75. Ndinowanzo bvunzwa nevatengi, vachiti kuchena kwehupfu hwemica kuri pa90. Mumamiriro ezvinhu akajairwa, kuchena kwehupfu hwemica kazhinji hakusi kwakakwira, kunongosvika 75 chete. Kana ikasanganiswa nezvimwe zvinozadza zvakaita secalcium carbonate, talc powder, nezvimwewo, kuchena kwayo kuchavandudzwa zvakanyanya.

2、 Upfu hweMica hune chimiro chakapfava. Tora beaker, wedzera 100ml yemvura yakachena, wobva wasanganisa negirazi rod kuti uone kuti kunyungudika kweupfu hwemica kwakanaka kwazvo; Zvimwe zvinozadza zvinosanganisira upfu hwakapfava, upfu hwetalc, calcium carbonate nezvimwe zvigadzirwa, asi kushanda kwavo kwekunyungudika hakuna kunaka seupfu hwemica.

3、 Isa chidimbu chidiki paruoko rwako, icho chine simba diki remapere. Upfu hweMica, kunyanya upfu hwesericite, hune simba diki remapere uye hunoshandiswa zvakanyanya mumaindasitiri akadai sezvizoro, machira, mapurasitiki, rabha, nezvimwewo. Kana upfu hwemica hwakatengwa husina simba kana kuti husina simba diki remapere, unofanira kungwarira panguva ino.

Mashandisirwo makuru ehupfu hwemica muzvipfeko.

Kushandiswa kwehupfu hwemica muzvipfeko kunonyanya kuratidzwa muzvinhu zvinotevera:

1. Mhedzisiro yekudzivirira: Zvizadza zvakaita sepepa zvinoumba hurongwa hwakakosha hwakafanana mukati mefirimu rependi, uye kupinda kwemvura nezvimwe zvinhu zvinoparadza mufirimu rependi kunovharwa zvakasimba. Kana upfu hwe sericite hwemhando yepamusoro hukashandiswa (chiyero chedhayamita kusvika pakukora kwechip kanenge ka50, zviri nani kanopfuura ka70), nguva yekupinda kwemvura nezvimwe zvinhu zvinoparadza kuburikidza nefirimu rependi inowanzowedzerwa katatu. Nekuda kwekuti zvizadza zve sericite powder zvakachipa zvikuru pane maresini akakosha, zvine kukosha kwakanyanya kwehunyanzvi uye kwehupfumi. Kushandiswa kweupfu hwe sericite hwemhando yepamusoro inzira yakakosha yekuvandudza mhando uye mashandiro ezvizadza zvekudzivirira ngura uye zvizadza zvekunze zvemadziro. Munguva yekuputira, zvizadza zve sericite zvinosangana nekumanikidzwa kwepamusoro pefirimu rependi risati rasimba, zvichigadzira otomatiki chimiro chakafanana uye zvakare pamusoro pefirimu rependi. Kurongeka uku kwechikamu nechikamu, nekutarisa kwaro kwakatarisana nekwakanangana nezvinhu zvinoparadza zvinopinda mufirimu rependi, kune mhedzisiro inoshanda kwazvo yekudzivirira.
2. Kuvandudza hunhu hwependi nehwemakanika: Kushandisa sericite powder kunogona kuvandudza hunhu hwependi nehwemakanika. Chinokosha ndechekuona hunhu hwependi, kureva chiyero chedhayamita nehukobvu hwependi yakaita sejira uye chiyero chehurefu nehurefu hwependi yefiller ine fibrous. Granular filler, sejecha nematombo ari mukongiri, inoita basa rekusimbisa simbi.
3. Kuvandudza kuramba kwependi: Kuoma kweresin pachayo kushoma, uye simba rezvizadza zvakawanda harisiwo rakakwira (senge talc powder). Kusiyana neizvi, sericite chimwe chezvinhu zviri mugranite, ine kuoma kukuru uye simba remuchina. Nokudaro, kuwedzera sericite powder se filler mu coating kunogona kuvandudza zvakanyanya kuramba kwayo kupfeka. Zvizhinji zve coating zvemotokari, road coating, mechanical anti-corrosion coating, uye madziro coating zvinoshandisa sericite powder.
4. Kushanda kwekudzivirira: Sericite ine simba rakawanda uye ndiyo inonyanya kushandiswa mukudzivirira kupisa. Inogadzira complex ine organic silicon resin kana organic silicon boron resin uye inoishandura kuita ceramic ine simba rakanaka remakanika uye inoshanda zvakanaka mukudzivirira kupisa kana ikasangana nekupisa kwakanyanya. Nokudaro, waya netambo dzakagadzirwa nerudzi urwu rwekudzivirira kupisa dzinoramba dzichichengetedza simba radzo rekutanga kunyangwe mushure mekupiswa nemoto. Zvakakosha zvikuru kumigodhi, matunnel, zvivakwa zvakakosha, nzvimbo dzakakosha, nezvimwewo.
5. Chinodzivisa moto: Upfu hweSericite chinhu chinokosha chinozadza moto. Kana chikasanganiswa nezvinhu zvinodzivirira moto zve organic halogen, zvinodzivirira moto uye zvinodzivirira moto zvinogona kugadzirwa.
6. Kudzivirira UV ne infrared: Sericite ine simba rakanaka pakudzivirira kubva ku ultraviolet ne infrared mwaranzi. Saka kuwedzera upfu hwe sericite hwakanyorova pa coatings dzekunze kunogona kuwedzera zvakanyanya kudzivirira UV kwependi uye kunonoka kukwegura kwayo. Kushanda kwayo kwe infrared shielding kunoshandiswa kugadzira insulation uye insulation zvinhu (zvakaita se coatings).
7. Mwaranzi inopisa uye machira anodziya zvakanyanya: Sericite ine kugona kwakanaka kwemwaranzi ye infrared, senge kana yakabatana ne iron oxide, iyo inogona kugadzira mhedzisiro yakanaka yemwaranzi inopisa.
8. Kudzivirira ruzha uye kubatwa neshock absorption effect: Sericite inogona kushandura zvakanyanya moduli yezvinhu, ichigadzira kana kuchinja viscoelasticity yazvo. Rudzi urwu rwezvinhu runonyatsotora simba re vibration, runoderedza simba re vibration waves nema sound waves. Pamusoro pezvo, kudzokororwa kwe vibration waves nema sound waves pakati pe mica chips kunoderedzawo simba razvo. Sericite powder inoshandiswawo kugadzira soundproofing, soundproofing, uye shock absorption coatings.
